This study evaluated the effects of intake of a mixed diet on chewing activity during eating and rumination and the relationship between the chewing activity and the particle size of the ruminated boli, ruminal digesta fractions and faeces in steers. Six ruminally cannulated steers received a mixed forage/concentrate diet (68:32, dry matter basis). The diet was offered twice daily at approximat...

Effects of Monensin on Dry Matter Intake, Milk Production and Healthy Transition Holstein Dairy Cows

The effect of varying dry matter availability on the conversion of dry matter resources to weight of calf at weaning was evaluated for nine breeds of cattle; Angus, Braunvieh, Charolais, Gelbvieh, Hereford, Limousin, Red Poll, Pinzgauer, and Simmental were recorded for 5 yr. Within each breed, four cows were assigned to each of four feeding levels of dry matter intake: 58, 76, 93, or 111 g of D...

four west african dwarf (wad) grower bucks averaging 6 kg in weight and aged between 5-6 months of age were used in a digestive trial to determine the intake and digestibility of raw or processed pigeon pea seed meal based diets. the diets designated rpbd, spbd, tpbd and bpbd were formulated from cassava peel, palm kernel cake, brewers dry grain, bone meal and common salt to contain 15% of raw,...

1Department of Animal Sciences, NDSU The objectives of this study were to determine the effects of forage inclusion level on growth performance, feeding behavior and carcass characteristics in finishing steers. These results indicate that a decrease in forage inclusion from 20 to 5 percent (dry-matter [DM] basis) in a finishing diet increases dry-matter intake (DMI), average daily gain (ADG) an...

I. Four sheep were given four diets containing proportions of rolled barley and soya-bean meal varied to provide 10.3, 13'3, 16.1 and 19.9 % crude protein in the dietary dry matter; the treatments were given according to a 4 x 4 Latin square design. The mean daily intake was 989 g dry matter. The apparent disappearance of protein, ash, ether extractives and carbohydrate before the abomasum, bet...

digestibility coefficient of whole cottonseed was determined by in vivo method and total collection feces. the whole cottonseed degradability was determined by nylon bag method. a number of 12 holstein bulls were used in a complete randomized design. the rations contained zero (control), seven, 14 and 21 percentages of whole cottonseed. during the experimental period, daily gain, dry matter int...

the present study was conducted to evaluate the effects of extruded linseed on milk production,dry matter intake and reproduction performance of 300 holstein lactating cows (35±15 days in milk;41±9/8 kg/day of milk production). cows were placed in a completely randomized design of 2treatments (concentrate containing 7 percent of extruded linseed vs. control), (150 cows pertreatment). cows were ...
