We conducted a lactation trial with a fresh forage diet in order to evaluate 1) the effects of monensin on nitrogen metabolism, and 2) the Cornell Net Carbohydrate and Protein System (CNCPS). Thirty Holstein cows in midlactation (eight fitted with ruminal fistulas) were gradually introduced to a fresh forage diet. A concentrate mix based on corn meal was fed before the a.m. and p.m. milking tim...

Rigorously standardized laboratory protocols are essential for meaningful comparison of data from multiple sites. Considering that interactions of minerals with organic matrices may vary depending on the material nature, there could be peculiar demands for each material with respect to digestion procedure. Acid digestion procedures were evaluated using different nitric to perchloric acid ratios...

This study aims to evaluate the effects of dietary concentrate: forage ratio (C:F) on development gastrointestinal tract in Tibetan lamb. A total 60 healthy two-month-old weaned black sheep (approximately 10.50 kg initial body weight) were assigned three treatments and fed C:F 70:30 (HC group), 50:50 (MC group) 30:70 (LC group). Using haematoxylin-eosin (HE) staining, morphological results show...

I. Sheep were given four Merent diets which contained two types of forage and two types of concentrate. The forage portion of the diet consisted of either hay or silage, while the low-oil concentrate had high levels of starch and in the high-oil concentrate this starch was replaced by an isoenergetic amount of soya-bean oil. 2. The effects of these diets on various factors in the blood was meas...

in this research, first eighty five percent of broad bean stover mixed with nine percent of wheat straw and six percent of sugar beet molasses ensiled and its digestibility determined by four mature weathers. in the next stage, broad bean stover silage (bbss) included in the ration of twenty male lambs with average body weight of 25.53±2.23 kg for 84 days in a completely randomized design. fora...

The effects of an increasing proportion of crushed linseed (CL) in combination with varying forage type (grass or corn silage) and forage to concentrate ratio (F:C), and their interactions on milk fatty acid (FA) profile of high-producing dairy cows was studied using a 3-factor Box-Behnken design. Sixteen Holstein and 20 Swedish Red cows were blocked according to breed, parity, and milk yield, ...
