Protein quality of feeding-stuffs

Proceedings: Antibiotic resistance in coliforms from animal feeding stuffs.

D. H. M. JOYNSON AND C. H. L. HOWELLS (Public Health Laboratory, University Hospital of Wales, Cardiff) Samples of animal feeding stuffs were examined for the presence of Gram-negative, lactosefermenting organisms (hereafter called coliforms) and the antibiotic resistance of any strain isolated was determined. Coliforms were found in 13% of all the feeds examined and of these organisms 64-4% we...

Effect of urea foliar feeding on grain protein content and quality in two winter wheat cultivars

Tiamulin hydrogen fumarate--veterinary uses and HPLC method of determination in premixes and medicated feeding stuffs.

Approved antimicrobial substances were treated as feed additives and used also as growth promoters until 2006. Regulation No 1831/2003 of the European Parliament and of the Council of 22 September 2003 on additives for use in animal nutrition changed the situation and at the moment antibiotics in feeds, except coccidiostats and histomonostats, can be used only as medicated feedingstuff. Medicat...

The importance of protein quality in animal feeding

The importance of protein quality for practical rations becomes evident as soon as an attempt is made to economize and to establish for such rations the lowest level of protein that will give efficient production. Woodman & Evans (195 I) demonstrated this point with pigs fed on a simplified barley-fine-bran ration. Supplementation with fish meal at the rate of 4.2% protein gave efficient produc...
