Abstract

Three multiparoys lactating sannen dairy goats in midlactation with mean milk production and DIM pf 1.5 ±0.22 kg and
167±4 days were used to determine effects of the abomasal infusion wheat starch, wheat starch or cottonseed oil with casein
on performance of sannen dairy goats. Goats were fed ad libitum with basal diet include, 40% hay alfalfa and 60%
concentrate. Treatments were abomasal infusion of 1 wheat starch (100g/d), 2 wheat starch and casein (100 g/d and 50 g/d
respectively) and 3 cottonseed oil and casein (45 g/d and 50 g/d). Infusion of starch of cottonseed oil with casein increased
milk yield, percentage and yield lactose, NPN, and whey protein were not affected by treatments. Infusion of wheat starch
with casein decreased milk fat concentration. Intake of DM, OM, CP, NDF, ADF and EE in total tract were not different
among treatments. No effect on ruminal pH, rumen ammonia concentration and glucose, blood urea nitrogen and triglyceride
of plasma were absorved. In general, it is concluded using of casein with starch and oil in postruminal had positive effect on
milk yield and milk protein
