ABSTRACT

The main characteristics of the beef production chain are set out in order to identify the chain links that hamper its development. The Uruguayan experience is shown. The importance of the time devoted to the productive process as to biological particularities of the biological cycle of beef production and the multiplicity of products generated during the industrial stage are two of the traits that should be taken into account to design a strategy addressed to the development of this process. The application of production technologies that fasten cattle growth and fattening, as well as market differentiation to efficiently sell products (high- and low-quality meat cuts) and byproducts (hide, viscera, fat) are two alternatives that encourage beef production. The strategy implemented in Uruguay has permitted a significant reduction in slaughter age by including supplementation in enclosure feeding for cattle production systems. The development of a public policy based on obtainment of sanitary status, on total cattle traceability, and on an electronic information system in the beef industry has allowed gaining international confidence, reflected in entering the most demanding markets, besides fulfilling the domestic market intake.

Key words: cattle; industry; markets; case study

Beef production worldwide is about 72 million tons per year (FAO 2022), which implies an annual average beef intake of 9 kg per person for planet inhabitants. Although specific recommendations on the amount of red meat that should be periodically ingested vary according to country, most of them suggest a maximum intake of 500 g of red meat per week (EUFIC 2022), which is equivalent to an annual average intake of 26 kg of meat. This difference shows the important margin of action to reach beef intake as protein source in the world’s population and to, thus, have an adequate feeding according to such standards. This poses the challenge of analyzing red meat production to fulfill such goal. The discussion of an agroindustrial complex with a chain approach permits identifying critical points in the whole process from production to intake.

The aim of this study was to make a brief characterization of the red meat production chain to identify possible chain links in which there are improvement opportunities for better economic and social outcome. For such purposes, information about the Uruguayan experience will be used to exemplify some processes of change recorded in the red meat productive model that have had an important impact on this country from the economic and social point of view.

Particularities of the beef value chain. A food value chain (FVA) implies activities and processes developed sequentially in its numerous links having as goal to fulfill the consumer’s demand through productive, economic, financial, informative and analytic functions (Briz et al. 2009, cited by Briz et al. 2010). In beef production, the food chain comprises all the activities starting in the rural environment with cattle breeding and ending in the commercialization of the end product for the final consumer, whether for the domestic market or the foreign market via exports. In this process, different stages can be identified: like the primary production stage (rearing, growing, fattening), marketing with or without middlemen, transport, slaughter, industrial processing, and selling to domestic consumers or exports.

The beef chain has two traits that turn out to be of fundamental relevance for an analysis to identify chain links that could enhance its bio-economical efficiency and that differentiate it from other agri-food chains. These two traits are the importance of the time devoted to the whole productive process, and the multiplicity of products.

In regards to the former, the beef productive process is characterized by the long duration of the different chain links. Nine months of gestation, six months of lactation, one or two years invested in growing, three or four months in fattening, and a period of around two months for slaughter, storage, freezing or vacuum packing and marketing give the beef chain high interest cost for the capital invested in every chain link. Thus, reduction of time involved in each chain link constitutes a key element to make the whole process more efficient and, hence, improve business profitability. This does not happen in the chicken or pork productive chains, productions in which time is shorter in each stage. Acknowledging time as limiting factor in the beef productive chain poses the challenge of analyzing every chain link critically to identify opportunities and reduce invested time. Certainly, overcoming time limitations demands primarily from chain links corresponding to rearing, growing and fattening, and not that much from industrial and commercial stages.

Figure 1 represents graphically the importance of time in the beef productive chain and the different chain components in which action can be conducted to improve this aspect. In this figure, the approach is organized from conception to intake (Taylor 1994), which symbolizes the process that goes from fertilization, represented by numerous spermatozoids and an ovule, up to the final consumer, represented by a beef portion on a costumer’s dish. In the hourglass verticals (symbolizing time function as process limitation), the business structure may be observed in each component of the beef productive model, as well as the information flow needed to make it a more efficient and profitable process.

In respect to the second trait, the beef productive chain acquires a particular complexity because, unlike other processes where only one product is generated as the result of the productive process (for instance, fruit and vegetables), in the beef productive model, multiple products are generated: dozens of beef cuts from the hind or the shoulder blade, with or without bone, edible viscera, hide, bone, blood, and fat, among others. This poses an important challenge to apply the chain approach to the beef productive model since it is necessary to analyze carefully in which way each of the chain links affects each product obtained. For instance, beef production of quality implies, for the most demanding markets, a minimum ratio of intramuscular fat, mainly in the hind cuts. Due to the fat deposition pattern, according to the fattening time (loin-head and ventral-dorsal), overfattening is shown in some beef cuts of the shoulder blades with bone, which could be less desirable under these conditions for consumers. This compels to establish a relation among different chain links to organize a design of multiple markets for each type of slaughtered cattle, and to consider different destinations for meat cuts for different consumers. Unlike what it is said, in order to analyze the time limitation, the problematic associated with the multiplicity of products affects the industrial and commercial stages. Figure 2 shows schematically the particular logic of the beef productive chain in respect to other more conventional productive chains.

Figure 2 Schematic representation of the particularity of the beef chain in respect to more conventional productive chains (relationship between production factors and amount of end products obtained) 

These two traits of the beef productive chain makes it particularly complex when analyzing ways of improvement, and it is precisely the chain approach the one that permits identifying the opportunities for strengthening each link in the chain. Table 1 provides these two peculiarities: the chain links where the peculiarity could be overcome and the ways to improve it.

Development of the beef productive chain: The Uruguayan case. Uruguay is eminently a cattle producer devoting 12 million hectares to cattle breeding for beef production, which represents 70 % of the total surface of the country. The stock consists of 11,800,000 head of cattle (INAC 2022a), showing an indicator of 3.4 animals/inhabitant. The raising of cattle is primarily pastoral, based on 80 % natural fields and 20 % sown pastures or improved natural fields (DIEA 2021). The raising is carried out by around 44,000 cattle farmers (DIEA 2021). The beef production complex of Uruguay has an annual production of 550,000 tons of beef, and around 70 % is exported and 30 % is devoted to the domestic market (INAC 2017). Even with this low ratio of the total production devoted to domestic consumption; Uruguay has a beef intake per inhabitant of 46 kg/year (INAC 2022b). Therefore, it is considered as one of the highest worldwide.

When considering the two limitations that affect the beef production chain, it is of interest to analyze ways of improvement that have been followed by this country to solve this problematic at the level of national resolution.

Time in primary beef production in Uruguay. Due to the biological impossibility of reducing gestation time, the real possibility of diminishing the length of the productive processes during the primary stage of the chain would be the reduction in the slaughtering age, which is attained mainly due to improvement in growing and fattening processes. This approach is the one followed in Uruguay. Figure 3 shows cattle slaughtering progress during the last 20 years at two ages of young cattle.

Figure 3 Progress in slaughtered cattle number in Uruguay at two ages of young cattle in the 2001-2021 period (Source: INAC 2022c

Although the amount of slaughtered cattle with temporary teeth is lower than the number of slaughtered cattle older than three years of age; in the historical series considered, there are records of a rate of almost 4,000 head of increment per year for younger cattle. If this trend is kept and continued as to slaughtering age in the last twenty years, this could have important implications in cattle stock composition, which could increase the number of cows reared and, thus, herd productivity in Uruguay. The outcome of this trend in oxen slaughtering may also be seen when the grouping of slaughtered cattle is performed annually by classifying steers into four categories: steers with temporary teeth, steers with two to four teeth, steers with six teeth, and steers with eight teeth. The results of this classification for 2002 and 2021 are shown in figure 4.

Figure 4 Classification of steers according to slaughtering age, years 2002 and 2021 (Source: Elaborated according to the web page of the Instituto Nacional de Carnes of Uruguay, INAC 2022c)  

The lower incidence on annual national slaughtering in total head of cattle as percent form in steers with eight teeth in the slaughtering of 2021, as compared to that of 2002, as well as the increase in the slaughtering of young cattle (steers with temporary teeth and steers with two to four teeth) marks a significant reduction in the average age of steers at slaughtering. Nevertheless, given this empirical evidence in regards to slaughtering age reduction, one could ask what sort of technology has been adopted by cattle farmers to attain these indices. Such question gains particular relevance when considering the high proportion of natural fields (of low productivity) in regards to the surface devoted to cattle grazing. The use of tools such as supplementation in grazing conditions and the strategic enclosure included in silvopastoral systems could account for this improvement in the individual performance during growing and fattening. In Uruguay, an important volume of information has been generated about the response to the use of supplements in growing and fattening in grazing conditions. Likewise, abundant information has been generated about the strategies of insertion of enclosure for growing and fattening cattle. Table 2 summarizes the information generated mostly in the Intensive Beef Production Unit (UPIC)1 of the Agronomy Faculty at the University of the Republic, as to technological alternatives, physical results, and technical coefficients that permit to assess the economic outcome.

Information in table 2 evidences that technological alternatives have been developed in Uruguay to improve individual performance in growing and fattening beef cattle efficiently as to the attainment of the productive objective, and they have been efficient, from the economic standpoint, in a wide scenario of prices for inputs and products. This scientific evidence has been assimilated by the beef chain, which has represented a very important modification in Uruguay. Besides information related to slaughtering age reduction, a fact that turns to be quite illustrative is the one referring to the percentage of slaughtered animals from pen feeding systems, which progressed from almost zero in the 90’s to 10 % in 2015 (Acosta, personal communication) and there is a prediction of getting up to 20 % at the close of 2022. The increasing demand of the markets for meat cuts from carcasses of more than 260 kg, and quality demands associated with pen fattening, as well as the availability of technological information on the use of enclosure based on feeds and local byproducts, suggest that this trend is going to be kept in future years.

Multiplicity of products generated in the chain and commercial engineering. The multiplicity of products generated by the beef chain provides a wide range that goes from thin beefsteak with high ratio of intramuscular fat (marbling) up to innards (rumen and reticulum). The strategy followed by different agents related to industrialization and marketing of the beef chain in Uruguay has been that of multiplying the options of final destination for products through the opening of international markets. Thus, beef products from Uruguay reach more than 100 countries, and represent the main exported good due to better prices and higher volumes of exports (INAC 2017). Therefore, increments are recorded above those for cellulose and soybean. In order to get to this situation, the Uruguayan beef chain has strengthened since 2002 because of a strategy of a public policy based on two key traits: (a) the goal of attaining certain sanitary status, according to the demands of the most demanding importing countries, and (b) the creation of a cattle information system, based on the traceability of all the cattle in the country, and an electronic information system for the beef industry with state-of-the-art technology.

In respect to the sanitary status, the beef chain from Uruguay dealt a blow in 2001 with the outbreak of aphtose fever in the country. After several years of total absence of this disease during the 90’s, the country was free of aphtose fever without vaccination. Consequently, in April 2001, Uruguay underwent the closing of the most important foreign markets with the corresponding economic and social consequences for the country. After some years, this situation was changed on the basis of a strategy of information transparency to the OIE (International Office of Epizootics) and the application of a strict sanitary control to fight against the spread of this disease, along with strategy of vaccination against aphtose fever, free and compulsory for all cattle farmers. As a consequence of this strategy of public policy, finally Uruguay attained the sanitary status of country free of aphtose fever with vaccination. Later, two other qualifications were added to this one. They were associated with the rank of country with negligible risk of bovine spongiform encephalopathy, and African horse sickness, free of classic swine fever, small ruminant plague, contagious bovine pleuropneumonia, and horse sickness (MGAP 2020); thereby permitting Uruguay to have access to markets with purchasing power, and positive consequences for the price of its main exportable item.

In regards to cattle traceability in Uruguay, since September 2006, it was stipulated that all cattle were identified with electronic and visual ear tags in order to guarantee their traceability. Uruguay is the only country in the world with all the cattle identified. This is a key element to put beef products in the foreign market since there is documented information available to make auditing easier for foreign countries, besides providing documented evidence for marketing with subjective trust arguments as to the origin and the possibility of creating more complex and sophisticated protocol systems. Besides, cattle farmers can have accurate and transparent data of every animal in the slaughtering process, and can plan the destination of the products according to the requirements of some markets in the productive and commercial plants, among many other benefits” (INAC 2016).

Along with cattle traceability, Uruguay has developed an electronic system of information of the whole industrial process in each refrigeration plant, based on setting control spots where information accumulated is recorded in black boxes, similar to those on planes. It is an electronic system to capture data from seven automatic weight recording spots during the process that goes from cattle incorporation to slaughtering houses up to their transformation into beef, and later sending to domestic or foreign markets. The seven spots are the following: (1) liveweight in the farm, (2) bleeding, (3) dressing, (4) post-dressing classification, (5) entrance to deboning, (6) deboning and packaging, and (7) delivery of beef cuts with bones and delivery of beef boxes (INAC 2022d). This volume of information is later centered in a unique database and is given to the cattle farmer and the industrial processer, thereby unifying the level of information for the different beef chain links. This system guarantees greater transparency in the whole process, and grants added value when products are placed in foreign markets. Figure 5 shows the destination of the beef exports from Uruguay in 2021.

Although China represents 59 % of the total volume, this market has great potential of compensation in respect to others, which generates an important commercial synergy. Access to the largest possible number of markets constitutes an efficient tool to solve the problematic of multiplicity of products in the beef chain, and avoids having unbalances in product demands. Hereafter, some examples are presented about the commercial logistics that allows a wide range of products.

  1. Commercialization of shoulder blade and hind products from the same slaughter. The combination of markets specialized in shoulder blade cuts such as the Kosher market2 and markets specialized in hind cuts such as the Hilton quota, permits a complement of most part of the beef products at good prices in terms of carcass average.

  2. Commercialization of products in the international market of beef cuts without bones and beef cuts with bones, from the same slaughter. The possibility of placing high-quality beef cuts (Hilton quota3 or quota 4814), with beef cuts with bones together with certain amount of beef for the Chinese market, permits a better use of the carcass making more efficient the industrial process.

  3. Specialization of links of the beef chain in markets that demand products from cattle fed in pens and fed on pasture. The total traceability of the cattle guarantees importers to know the beef origin, as to the feeding system, with unequivocal positive consequences in terms of specialization of the productive process. The emergence of the quota 481 market that demands beef from pen-fed cattle, combined with the Hilton quota, which requests cattle fed exclusively on pasture, has played a dynamic function for the beef productive chain.

  4. The balance between beef cuts with bones primarily for the domestic market and beef cuts without bones for exports permits the industry and important complement to avoid unbalances in terms of carcass meat produced.

  5. The development, though still incipient, of markets demanding beef with high level of marbling5 from heavy carcasses (350 kg of carcass weight), has promoted a segment specialized in the production of cattle specifically for this product, with important implications in rearing, growing, fattening, industrial processing, and commercialization.

This national strategy, as public policy to strengthen the beef productive chain, has allowed, besides fulfilling the demand of the domestic market, the access to most demanding markets such as Europe, United States, Japan, Israel, and the Russian Federation, among others.

Final considerations

Global beef consumption is around 8 kilos per person per year, while WHO recommends an intake of 25 kg per person per year, which marks an important growth margin for this protein source, and an opportunity of growth for producing countries. The approach of agri-food chain permits analyzing critically all the links in the chain in order to identify the points that need to be strengthened. Nevertheless, the beef chain shows two particularities that hamper the analysis. The long periods from the biological standpoint, mainly in the primary production stage, compel to formulate technological alternatives that redirect production to remove this limitation. Likewise, the multiplicity of products obtained forces to analyze the logistics of marketing to compensate that produced by an animal and put it in different markets. The Uruguayan experience has been enriching because it has attained a technological adoption process on the part of the cattle farmers that has been reflected on labor age. At the same time, the development of a public policy based on the obtainment of a sanitary status, the total traceability of the cattle and an electronic information system in the meat industry have allowed to gain international confidence, reflected in the entrance to the most demanding markets, besides fulfilling the domestic market intake.

2Posteriormente, se hacen inspecciones, como el inflado de los pulmones para descartar adherencias pleuropulmo. Definition given to the prepared foods according to the feeding Judaic laws established in the Tora (Jew law book). In the case of the Kosher beef, should come from the slaughtered animals under religious supervision; the animal should not previously insensitive and should slit the throat with a special knife which sectioned the big vessels (carotid artery and jugular vein). Later, inspections are made, as the lung inflation to discard pleura- pulmonary adhesions. The approved carcass are rigorously identified (Robaina 2002).

3The Hilton quota is a customs quota of the European Union (UE), originated in the Tokyo Round of the GATT in the year 1980. It comprises high-quality meat cuts and started in 1,000 tons of weight of product granted to Uruguay, out of a total of 21,000. After a series of increments, at present, it corresponds to 6,300 tons, out of a total of 58,100. The customs tariff of the Hilton quota is 20 %. Beef exports to the EU not included in this quota, have a customs tariff of 12.8 % plus 1.764 at 3,041 Euros/ton of specific rights, according to the product (Robaina 2002).

4The 481 quota is a customs quota of the European Union, with 0% of rights of import for fresh meat of high quality, refrigerated or frozen. Meat should come from steers or heifers of less than 30 months of age, that in 100 days prior to slaughter have been fed rations defined as to minimum percentages of concentrates, metabolizable energy and dry matter in respect to liveweight (Robaina 2002).

5Indicator of the quality of the intramuscular fat that is assessed by visual inspection of the beefsteak. In general, a scale of six degrees is used. Marbling acts as double indicator, qualitative and quantitative. It is related to the amount of intramuscular fat and meat juiciness. Fat abundance is a meat quality indicator for certain markets. Nevertheless, it imposes limitations because marbling increment implies low ratio in lean meat percentage in cattle (Robaina 2002).
