Response of Shami goats and kids to variable levels of soyabean or sunflower oils in diets
Journal Title: Journal of Animal and Feed Sciences - Year 2011, Vol 20, Issue 4
Abstract
A study was conducted to determine the effect of feeding soyabean or sunflower oil to lactating Shami goats on milk production, composition and fatty acid profile. Goats (n=125), 2 to 4 years of age and 55 to 60 kg liveweight, were randomly assigned to 5 treatment groups (25 each) in a completely randomized design. Diets were: a control ration (C), control supplemented with 3% soyabean oil (3%SBO), control supplemented with 5%SBO, control supplemented with 3% sunflower oil (3%SFO), and a control supplemented with 5%SFO. Variables measured were milk production, milk composition, dry matter intake, body weight, weaning weight of kids, blood metabolites, and milk and blood fatty acid profiles. Daily milk production was reduced (P<0.05) in most treatments. Fat and protein yields were maximum (P<0.05) at 3%SBO while energy corrected milk was highest (P<0.05) for the 3%SBO. Feed intake was least (P<0.05) for the 3%SFO group and feed to milk ratio was highest (P<0.05) for the 3% SBO group. Values for the serum cholesterol were highest (P<0.05) for the SBO kids. Meanwhile, triglycerides were reduced (P<0.05) following oil treatment with the lowest (P<0.05) value in the serum of the 5%SBO kids. Total conjugated linoliec acid (CLA) content in milk was mostly increased (P<0.05) for oil treated goats. In the blood of kids, total CLA was maximum (P<0.05) for kids of the 5%SFO group. Results indicate that supplementing lactating goat diet with either oils did not improve milk production, milk composition, or growth rate and weaning weight of their kids, but improved their energy corrected milk and CLA content. However, only SBO increased cholesterol level in the blood in kids.
