Abstract

We studied the effect of soybean or flaxseed oil feeding in the diets of lactating Anglo-Nubian goats. A total of 20 goats (33.6 ± 0.6 kg) were divided into four treatments and fed a basal diet of berseem clover and concentrates (40:60 DM basis; control) or the control diet supplemented with either 20 mL/day of flaxseed oil or soybean oil or 10 mL of soybean oil plus 10 mL of flaxseed oil per day for 12 weeks (i.e., 22 to 23 g per kg of DM intake). Oil inclusion decreased ruminal pH (P < 0.05), and acetate but increased (P < 0.05) total volatile fatty acids and molar proportion of propionate and blood glucose (P < 0.01). In addition, increased milk yield and decreased milk-fat contents were evident (P < 0.05) with oil supplementation. Diets containing oil increased (P < 0.05) unsaturated fatty acids (FA), conjugated linoleic acid, and the athrogenicity index of milk fat but decreased saturated FA concentrations. It is concluded that soybean-oil or flaxseed-oil supplementation of goats at 20 mL/day increased feed utilization and milk production.
