BARBOSA, L.P. et al. Testicular morphometry of goats fed licury (Syagrus coronata) oil. Arq. Bras. Med. Vet. Zootec. [online]. 2012, vol.64, n.4, pp. 804-809. ISSN 0102-0935. http://dx.doi.org/10.1590/S0102-09352012000400003.
A trial was carried out to identify the best level of licury (Syagrus coronata) oil in the diet of goats. Nineteen ¾ Boer male goats at three months of age were kept in individual pens. These animals were submitted to 75 days of confinement. The rations were composed of corn and soybean meal, Tifton 85 chopped hay and levels of licury oil (dry matter base). The animals were arranged in four groups according to the addition of licury oil to the diet: 0.0 (no oil inclusion, n= 5); or addition of 1.5 (n= 5); 3.0 (n= 5); or 4.5% licury oil. The evaluations of mean body weight and testicular biometry were performed weekly. After confinement, animals were slaughtered and the weight of the left and right testicles, left and right epididymal weight; and gonadosomatic index were determined. The addition of licury oil up to 4.5% to the diet of prepuberal male goats has not change the testicular development based on its biometrical and morphometrical parameters. It is suggested that licury oil can be added up to 4.5% to the diet of male goats.
