Effect of varying concentrate feeding levels on some traits in lactating goats.
9 lactating goats were divided into 3 groups based on their milk yield and were fed concentrate over 6 weeks at levels of 0, 0.7, and 1.4 kg/d. Increased concentrate feeding caused a significant increase of the blood glucose content and a significant decrease of the milk fat content. Milk yield, liveweight, and protein content of the milk as well as the blood ketones were not influenced significantly by concentrate feeding. The 1.4 kg/d variety did not yield any considerable increase of the milk performance and decreased the milk fat content. From the point of view of feed economy, practical feeding of milking goats with 0.7 kg/d concentrate is therefore recommended.
