FRANQUEZ, Pamela et al. Performance traits and indexes of the intake pattern of fattened pigs with fresh paste of whole avocado. Cuban J. Agric. Sci. [online]. 2017, vol.51, n.3, pp.329-336. ISSN 0864-0408.

A total of 16 Yorkshire x Landrace pigs, castrated males and females in a 1: 1 ratio, with an average of 67.0 kg of live weight, were randomly distributed in two treatments, which consisted of diets formulated to contain 0 and 21 % of fresh paste of waste avocado (Persea americana Mill.). The paste was made up of ripe whole fruits, and contained 14.3 % of crude fiber and 49.2 % of ether extract. There was a significant decrease (P = 0.001) in food intake and feed conversion in animals fed with avocado diet (2.34 kg DM/d and 2.75 kg DM/kg gain) with respect to those of the control diet (3.30 kg DM/d and 3.13 kg DM/kg gain). The performance traits were significantly correlated (P = 0.001) between each other. The animals intake less (58.3 %) of the food offered with paste with respect to the offer that did not contain it (74.4 %) (P = 0.143). The ingestion speed decreased from 50.1 to 31.5 g fresh / min (P = 0.027) and from 43.5 to 17.7 g DM/min (P = 0.001). It is suggested that 21 % of fresh paste of waste avocado in the diet influences positively on the feed conversion efficiency of finished pigs, but the weight gain decreases when the voluntary intake of food reduces.
