Twenty-four Jonica kids, artificially reared, were used: ten kids (six male and four female) weaned at 45 days of age and 14 (eight male and six female) at 60 days. From the beginning of the trial (45 d of age) up to 70th day, all kids were given a commercial complete mixed feed for weaning that, in the following phase (70-170 d), was replaced by a commercial fattening ration. Kids weaned later at 60 days showed a better feed conversion, a higher final weight (P<0.05), a lower yield loss, better dressing percentage, better shaped carcasses and more tender (P<0.01), higher water content (P<0.05) and darker LD muscle. These results show the drawbacks of early weaning of kids.

Abstract
Twenty-four Jonica kids, artificially reared, were used: ten kids (six male and four female) weaned at 45 days of age and 14 (eight male and six female) at 60 days. From the beginning of the trial (45 d of age) up to 70th day, all kids were given a commercial complete mixed feed for weaning that, in the following phase (70-170 d), was replaced by a commercial fattening ration. Kids weaned later at 60 days showed a better feed conversion, a higher final weight (P<0.05), a lower yield loss, better dressing percentage, better shaped carcasses and more tender (P<0.01), higher water content (P<0.05) and darker LD muscle. These results show the drawbacks of early weaning of kids.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
