A system for automatic registration and individual recognition of feed pecking (activity and quantity) in groups of free running hens was tested. A PIT (Passive Integrated Transponder)-tag system was used to separate and register individuals when they were feeding. An electronic balance system placed under the feeder registered the amount eaten by each individual on a PC. A test with two differ...

The majority of Salmonella strains isolated in veterinary laboratories in Poland in 2001 originated from poultry (82%), swine (4%), and animal feeding stuffs (10%). Thirty-two serovars were observed among tested strains. Antimicrobial susceptibility testing revealed the recent trends in Salmonella resistance. The increase in the number of resistant strains was observed. Multiresistance occurred...

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...

Commonwealth contributions to the British diet 83 Thus, the supplies of bacon from Commonwealth sources are unlikely to increase as fast as supplies from home production, and supplies from European sources are already increasing. There is, however, one new possibility in the future, the production of pigs as part of the grain-sorghum scheme in Queensland. It is too soon as yet to estimate the p...

The nutritive value of manganese and its occurrence in animal and plant tissue has received considerable attention within the last few years. The literature relating to manganese in plant tissue has been reviewed by Lindow and Peterson (^)^, who reported analyses of 84 samples representing the principal classes of human foods. In a later paper by Skinner and Peterson {12), analyses of 54 feedin...
