GRANDE, P.A. et al. Carcass evaluation of Saanen kids fed oilseeds diets. Arq. Bras. Med. Vet. Zootec. [online]. 2011, vol.63, n.3, pp. 721-728. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352011000300025.
Sixteen non-castrated Saanen kids from 15.16±1.60kg to 30.61±0.33kg of body weight, allotted into completely randomized experimental design, were fed experimental diets (treatments) containing flaxseed, sunflower, or canola oilseeds, and a control diet based on oat hay, soybean meal, ground corn, and vitamin-mineral supplement. Hot and cold carcass weight, carcass and commercial cuts yields were not modified by treatments. Canola seed in diets resulted in greater weight loss by cooling and lower loin fat proportion. Loin bone proportion was higher for kids fed flaxseed or canola. The moisture, protein, lipid, and ash contents in the Longissimus dorsi were not affected by oilseeds inclusion. Flaxseed in the diet increased the omega-3 content in muscle. Cholesterol content and omega-6/omega-3 ratio were lower to the treatments with flaxseed, sunflower, and canola. Oilseeds in diets of Saanen kids did not alter the carcass quantitative traits, but improved the quality of meat, with less cholesterol and more omega-3 using flaxseed.
