Carcass and non-carcass traits of single and twin lambs



Carcass and non-carcass traits of single and twin lambs



Arquivo Brasileiro de Medicina Veterinaria E Zootecnia 66(2): 602-608



An experiment was conducted to evaluate the carcass and non-carcass traits of single and twin lambs. Sixteen Texel x Ile de France crossbred, non-castrated male lambs were weaned at 56 days of age and slaughtered at 28kg of body weight. Immediately after the slaughter each body component was individually weighed, while carcasses were evaluated after a 24h period of refrigeration at 2 degrees C. Single lambs presented higher values of carcass weight and carcass dressing percentage. Moreover, the Longissimus muscle area was also greater for single lambs. On the other hand, as a proportion of empty body weight, rumen was greater for twin lambs, increasing their gastrointestinal content at slaughter. The results of this study indicated that at a same slaughter weight single lambs have better quality carcasses in comparison with those from twin lambs.
