Effects of feeding frequency on intake, ruminal fermentation, and feeding behavior in heifers fed high-concentrate diets.
Four ruminally fistulated Holstein heifers (BW = 385 +/- 6.2 kg) were used in a 4 x 4 Latin square experiment to determine the effect of feeding frequency on intake, water consumption, ruminal fermentation, and feeding and animal behavior. The treatments consisted of different feeding frequencies: a) once daily (T1); b) twice daily (T2); c) 3 times daily (T3); and d) 4 times daily (T4). Heifers...

15 صفحه اولEffect of Concentrate Feeding Level on Production of Holstein Cows Grazing Winter Annuals
A replicated randomized block trial was conducted to determine the response of Holstein cows rotationally grazing annual ryegrass-Crimson clover pasture to supplemental concentrate. Within each of 2 yr, 16 Holstein cows were assigned to one of four blocks by energy-corrected milk yield, days in milk, and parity. Treatments included one of four levels of concentrate based on the following grain ...
متن کاملEffects of dietary nonstructural carbohydrates and protein sources on feeding behavior of tethered heifers fed high-concentrate diets.
To describe the feeding behavior of growing heifers fed high-concentrate diets with different sources of protein and nonstructural carbohydrates, and to explain the ruminal fermentation pattern, 4 ruminally fistulated Holstein heifers (BW = 132.3 +/- 1.61 kg) were assigned to a 4 x 4 Latin square design with a 2 x 2 factorial arrangement of treatments. Two non-structural carbohydrate sources (b...
متن کاملEffects of feeding high-concentrate diets at restricted intakes on digestibility and nitrogen metabolism in growing lambs.
In Trial 1, 12 wether lambs (34.2 +/- .8 kg BW) were used to determine the effects of restricting intake of diets increasing in percentage of concentrate, to achieve isoenergetic intakes, on digestibility and N metabolism. The trial consisted of two 14-d periods, 9 d for adaptation and 5 d for total collection of urine and feces. Treatments were 22, 39, 61, and 92% concentrate diets fed at ad l...
