Protei"enbronne in die rantsoene van groeiende varke 1. 'n vergelyking tussen vismeel en verhitte volvet sojaboonmeel

Summary: protein sources in the diets of growing pigs.1. A comparison between fish meal and heated full-fat soyabean mealTwo trials, one with porkers and one with baconers were conducted to determine the influence of heated full-fat soyabean meal as protein source on their growth, feed utilization, carcass development and fat refraction-index values. The results indicated that it is possible to substitute fish meal as protein source, on a biological base, with soyabean meal in diets with equivalent protein and energy levels.Twee proewe, een met vleis- en een met spekvarke, is uitgevoer om die invloed van verhitte volvet sojaboonmeel as proteienbron op hul groei, voeromset, karkasontwikkeling en refraksie-indekswaardes van karkasvet te bestudeer. Die resultate in die studie verkry dui daarop dat verhitte volvet sojaboonmeel wel vismeel suksesvol as proteienbron op 'n biologiese basis, in rantsoene met ekwivalente proteien- en energiepeile kan vervang
