BLANCO-BETANCOURT, Dairom et al. Effect of the bioproduct IHplus® on the productive and health indicators of pre-fattening pigs. Pastos y Forrajes [online]. 2017, vol.40, n.3, pp. 201-205. ISSN 2078-8452.
A study was conducted under production conditions in order to evaluate the effect of the bioproductIHplus® on the productive [(live weight increase, LW; mean daily gain, MDG; feed conversion, (FC) and health indicators (sick, recovered and dead piglets]; and epizootiological indicators: prevalence, IPV; negative incidence per recovery, NIR; mortality, (Mt) of pre-fattening pigs. A total of 480 animals were used, with average age of 26 days and average weight of 5,96 kg. Starter concentrate feed for piglets (of national origin) was used as feedstuff. The experimental period was 21 days. Four treatments were evaluated: a control and three doses of IHplus®: 40, 80 and 120 mL piglet-1 day-1, in a completely randomized design. The worst productive results were obtained with the control treatment (7,26 kg LW; 60,5 g day-1 MDG and 6,01 FC) and with the lowest probiotic dose (7,22 kg LW; 60,5 g day-1 MDG and 6,01 FC); while with the dose of 120 mL the best results were obtained (7,92 kg LW; 92,3 g day-1 MDG and 3,98 FC). The health indicators with 80 and 120 mL piglet-1 day-1 showed lower prevalence, and the highest dose exerted the best effect on them; these treatments reached a recovery rate of 100 %, with 0 % of mortality. It is concluded that the dose of 120 mL of IHplus® piglet-1 day-1 produced a higher effect than the other doses on the productive and health indicators of piglets, for which it is recommended as optimum application dose in the diets.
