The measurement of feed efficiency in the broiler industry is one of pri­ mary measurements used to monitor and evaluate broiler performance. It has a significant impact on the competitiveness in the marketplace as nearly 70% of the cost of raising a commercial broiler is feed. Although feed costs may shift up or down, it will always represent the highest input cost in commercial poultry produc...

A sheep digestion trial and two feedlot trials with cattle were conducted to study effects of an ionophore, salinomycin, on nutrient digestibility, ruminal metabolism and cattle performance. In trial 1, addition of salinomycin at 5.5, 11 or 22 ppm to 60% concentrate diets fed to ruminal-cannulated rams had no effect (P greater than .05) on apparent digestibility of dry matter (DM), organic matt...

Fats and oils, a.k.a. lipids, are a chemically diverse group of compounds with the highest energy density among all major macro nutrients. Lipids play an important role in commercial turkey diets both physically and physiologically. From a physical standpoint, lipids are associated with processes related to improvement of live weight gain and feed efficiencies in commercial turkeys. Breeder tur...

This study was conducted to evaluate the effects of the different levels of vermi (Eisenia fetida) meal on fermented ration in broiler chicken growth and profitability under two management systems. For this purpose, 120 day old broiler chickens (cobb vantress) were tested in a Completely Randomized Design with four (4) dietary treatments: first, the commercial feeds (control), second, 2% vermi ...

At the end of 1984 a collaborative survey was carried out to determine the prevalence of infection with human T cell lymphotropic virus type III/lymphadenopathy associated virus (HTLV-III/LAV) and HTLV-I among 584 recipients of various blood products in Britain at that time. In 204 cases yearly point prevalence figures for infection were also obtained for 1978 to 1983. In 1984, 215 of 315 patie...

As ruminants are able to digest fibre efficiently and assuming that competition for feed v. food use would intensify in the future, cereals and other field crops should primarily be destined to cover the dietary needs of humans and monogastric animals such as poultry and pigs. Farming systems with a reduced or absent concentrate supplementation, as postulated by organic agriculture associations...
