Sawdust in Purified Chick Rations

A Comparison of Certain Antibiotics in Several Chick Starter Rations

Immunogenicity and feasibility of purified chick embryo cell vaccine.

Two hundred seventy-one children reported at the WHO Collaborative Centre for Rabies Epidemiology for South-East Asia at National Institute of Communicable Diseases, Delhi, for advice and antirabies antibody assessment after post-exposure prophylaxis with purified chick embryo cell (PCEC) antirabies vaccine from January 1986 to October 1992. Vaccine was very well tolerated by these children and...

Ionophores 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...

Roughage 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...

Rice bran in swine rations

R i c e bran has received increased attention as a feedstuff for swine and as a source of oil for human consumption. Depending on milling conditions and hull contamination, bran from California rice contains 15 to 20 percent oil, 30 to 40 percent digestible carbohydrate, and 12 to 14 percent protein, although levels of up to 18 percent protein have been reported. Rice bran is also an excellent ...
