SLUKWA, M.A.. Efecto del destete precoz y engorde a corral sobre la calidad de res en corderos. Rev. vet. [online]. 2014, vol.25, n.2, pp.135-139. ISSN 1669-6840.

The objective of the trial was to compare the carcass quality of unweaned lambs versus early weaned lambs fed with different diets. Sixty lambs Ideal crossbreed, 2 months-old, were randomly distributed in 3 groups of 20 animals each (10 males and 10 females). A control group (T) continued breastfeeding while remaining animals were submitted to early weaning and fed with isoenergetic and isoproteic diets, with proteinbased soybean expeller (S) or sunflower (G). At the time of traditional weaning (120 days of age), lambs from the three treatments were slaughtered to assess the quality of carcass and fat content. A completely randomized experimental design was used, being the animal the experimental unit. Subjective measures of the carcasses were compared by means of the Chi-square statistical analysis. The lambs of group S revealed greater rib depth and increase of carcass compactness, at similar levels to those of the group T. Such indicators were lower in the animals of group G.

Keywords : lamb; early weaning; soybean and sunflower diets; carcass quality.
