Improvement of feed efficiency in dairy farming economically has a great importance. In this study, the genetic parameters of net energy efficiency and its relationships with milk yield, 3.2% fat corrected milk, body weight, gross income and income over feed costs were investigated, by the 2589 monthly records collected from the 723 lactating cows in the 3 herds. The different requirements of e...

An experiment was conducted in early lactating buffaloes for the period of 3 months in Jadakheria and Polisimal village of LimkhedaTaluka in Dahod district of Gujarat to assess the effect of supplementation of bypass fat on milk production, composition, body weight change and economic efficiency. Forty buffaloes in their 2nd and 3rd lactation were equally divided in completely randomized design...

The objective of this study was to estimate the relation of body condition score (BCS) near calving to the body condition change in early lactation, the reproductive performance, milk yield and culling rate in the first lactation Estonian Holstein dairy cows. Cows were divided into three groups based on their BCS at calving; thin, BCS ≤3.0 (n=29); moderate, BCS 3.25–3.5 (n= 48); and fat, BCS ≥3...

The aim of this study was to investigate the effect of diets containing roasted soybean (R), extruded soybean (E) or their combination (RE) on dairy cow performance and milk fatty acid (FA) profile. Nine multiparous lactating Holstein cows (680 ± 25 kg BW; 90 ± 10 DIM; means ± SD) were randomly assigned to a triple 3 × 3 Latin square design. Dry matter intake (DMI), apparent nutrient dige...

the objective fllowed in the present study was to evaluate the effects of different milkingfrequencies on milk production and on blood metabolites in holstein cows. sixty-six fresh holsteincows were allocated to two treatments namely: 4 (4x) vs. 6 times (6x) of daily milking, during the first3 months of lactation, and then switching on to a three times of daily milking until end of the lactatio...

We used 24 multiparous Holstein cows in 4 × 4 Latin square design to evaluate full-fat corn germ as a replacement for whole cottonseed and tallow in total mixed diets for lactating dairy cows. Experimental diets on a dry matter basis were: 1) control 3.5% fat; 2) whole cottonseed 5.1% fat; 3) tallow 5.1% fat; 4) full-fat corn germ 5.1% fat. Diets were fed as total mixed rations typical of that ...

Twenty-four lactating Holstein dairy cows were used in a completely randomized design to investigate the effect of soybean meal (SM) and xylose protected soybean meal (XSM) in combination with ground (GB) or steam flaked (FB) barley on dry matter intake, milk production, rumen fermentation and blood responses. The experimental period lasted for 30 days. The diets consisted of the provision of 1...
