The rations were compounded in their country of origin ; half of each consignment was used at the home station and the other half shipped to the overseas station. 2.

متن کاملAssessing Nitrogen and Phosphorus in Excreta from Grower-finisher Pigs Fed Prevalent Rations in Vietnam*
Livestock production in Vietnam is, as in most Asian countries, increasing rapidly and changing into specialized highly intensified operations. The volume of animal excreta generated exceeds the capacity of the operation land base and cannot be utilized efficiently. As a consequence, there is a loss of plant nutrients from livestock farms that causes environmental pollution. This study carried ...
متن کاملBiological Value of Casein as a Supplement to the Proteins of Barley in Rations for Pigs
It has been shown at the California Agricultural Experiment Station by Thompson and Voorhies (7) ^ and by Hughes (2) that barley, when fed as the only source of protein, does not produce optimum growth in pigs. Protein-rich concentrates like fish meal and tankage or dairy byproducts when used as supplements to barley, produce more rapid growth. Such concentrates, however, contain other nutrient...
متن کاملIonophores in Dairy Rations
Introduction Ionophores have been used extensively in the beef industry in Canada since 1977. Until recently, there has been no label indication for use of ionophores in lactating dairy cattle. Ionophores are feed additives that alter rumen microbial populations through ion transfer across cell membranes. In Canada, the label warning prohibiting the use of Rumensin premix in lactating dairy ca...
متن کاملRoughage Levels in Feedlot Rations
vitro digestibility tended to be greater with ammoniation. In the second trial, very high levels of ammonia, urea or glucose were added. Levels of insoluble protein were much higher in this trial than the other. This reflects the high variability of corn silage. Recovery of nitrogen added as ammonia averaged 82 percent while all of the nitrogen added as urea was recovered. The amounts of insolu...
