An effective method for genetic modification of chickens has yet to be developed. An efficient technology, enabling production of transgenic birds at high frequency and with reliable expression of transgenes, will have many applications, both in basic research and in biotechnology. We investigated the efficiency with which lentiviral vectors could transduce the chicken germ line and examined th...
The effects of four dosages of conjugated equine estrogens (Premarin) on atherogenesis and on plasma, liver and bile lipids were studied in cockerels maintained on a high-fat, high-cholesterol diet. A lowering effect, not dosedependent, occurred in plasma linoleic and linolenic acid. An augmentative effect, varying with dose, occurred in plasma phospholipids, plasma palmitic, stearic and oleic ...
Rice polishing is a by-product of rice milling. It is a good source of energy and an assortment of amino acids. The anti-nutritive factors associated with rice polishing reduce the availability of amino acids and other nutrients to poultry. Defatted rice polishing (DRP) was chemically treated with 0.4N HCl and 6% H2O2 solutions by soaking in ratio of 1:1.5. After the chemical treatments, one po...
A 10 wk trial was conducted to investigate the effect of using ground, sterilized eggshell as a calcium source in breeder male diets. Live performance, semen quality, gonadal and visceral organ characteristics, plasma calcium concentration and bone mineralization were evaluated. Forty-five Rhode Island Red cockerels aged 25 wk were caged individually in a conventional open-sided house. The bird...
