QUEIROGA, Rita de Cássia Ramos do Egypto et al. Production and chemical composition of the milk from crossbred Moxotó goats supplemented with licuri or castor oil. R. Bras. Zootec. [online]. 2010, vol.39, n.1, pp. 204-209. ISSN 1806-9290. http://dx.doi.org/10.1590/S1516-35982010000100027.
The effect was assessed of including licuri and castor oils in the diet on the production and chemical composition of milk from goats and the economic viability of the diets. Crossbred Moxotó goats in a 5 × 5 Latin square design were used with two replications consisting of five diets: a control treatment without supplementary oil (control), and the others with 3% or 5% licuri or castor oil. Milk production decreased with the inclusion of 5% licuri oil, but it did not influence the production of milk corrected to 4% fat. The addition of 3% castor oil reduced the fat content and total solids production compared to licuri oil, but it increased the lactose content. There was no significant difference in the protein content among treatments. The simple financial analyses showed that the control diet was more profitable, but supplementation with 3% licuri oil when compared to castor oil supplementation can be an alternative when the milk is for processing because of the higher fat content.
