Italy is known for its tradition in goat farming and the Sarda autochthonous goat from Sardinia is one of the most important breeds of the Mediterranean Basin. The suckling kid from this breed is a traditional meat product and, despite the good acceptance by the consumer, it is not recognised with a protected geographical indication or designation of origin mark. In order to give a first cognitive insight into the main productive and quality characteristics of carcass and meat, a total of 40 kids (20 males and 20 females) milk fed by their dams and slaughtered at 42 days of age were studied. In vitam and post mortem performance traits were registered. These included the sectioning in commercial parts and their dissection into the different tissue components: muscle, separable fat and the bone + tendon. Chemical composition, fatty acid and cholesterol content were determined from the longissimus dorsi muscle. Student’s t test was applied to evaluate the differences between the sexes. In vivo parameters were similar between sexes, and differences between sexes were registered for height at withers, rump length and body length, with higher values in males. Males showed better carcass yields which were longer and with higher hip width. Carcasses, classified as first quality in both sexes, were characterized by a low content of adipose tissue and a good percentage of muscle, and showed the tissue composition similar between sexes, except for the lower content in muscle tissue of the leg from males. The low lipid deposit suggested the possibility to increase the age and weight at slaughter, in order to improve the commercial value of this product. The chemical composition of the longissimus dorsi muscle was similar between the sexes, while cholesterol content, oleic acid and MUFA (Monounsaturated Fatty Acids) were lower in males than females. In conclusion, meat had low cholesterol and lipids content, confirming that the Sarda suckling kid has an excellent nutritional value.

Abstract
Italy is known for its tradition in goat farming and the Sarda autochthonous goat from Sardinia is one of the most important breeds of the Mediterranean Basin. The suckling kid from this breed is a traditional meat product and, despite the good acceptance by the consumer, it is not recognised with a protected geographical indication or designation of origin mark. In order to give a first cognitive insight into the main productive and quality characteristics of carcass and meat, a total of 40 kids (20 males and 20 females) milk fed by their dams and slaughtered at 42 days of age were studied. In vitam and post mortem performance traits were registered. These included the sectioning in commercial parts and their dissection into the different tissue components: muscle, separable fat and the bone + tendon. Chemical composition, fatty acid and cholesterol content were determined from the longissimus dorsi muscle. Student’s t test was applied to evaluate the differences between the sexes. In vivo parameters were similar between sexes, and differences between sexes were registered for height at withers, rump length and body length, with higher values in males. Males showed better carcass yields which were longer and with higher hip width. Carcasses, classified as first quality in both sexes, were characterized by a low content of adipose tissue and a good percentage of muscle, and showed the tissue composition similar between sexes, except for the lower content in muscle tissue of the leg from males. The low lipid deposit suggested the possibility to increase the age and weight at slaughter, in order to improve the commercial value of this product. The chemical composition of the longissimus dorsi muscle was similar between the sexes, while cholesterol content, oleic acid and MUFA (Monounsaturated Fatty Acids) were lower in males than females. In conclusion, meat had low cholesterol and lipids content, confirming that the Sarda suckling kid has an excellent nutritional value.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
