1. TYPES OF FEEDS, CONCENTRATES AND ROUGHAGES Based on the nutrients they supply the nutrients in animal feeds can be classified into six groups, viz: 1. The term aflatoxins refers to a particular group of mycotoxins produced by some At the age of 16 wks, 10 males and 10 females were selected from each research group and slaughtered (30 birds were slaughtered altogether). through the animal’s body and absorbs the products of digestion. 0000014670 00000 n other types of feeds that are complemented to feeding of home made concentrates. 0000013872 00000 n The nature of the investments has been such that primary producers of broiler parent breeding stock and day-old chicks have also invested in animal feed pro-duction. Minerals can be divided into two types – Macro and Micro. Feed is supplied to the integrated poultry farming operations and the external feed market. 0000045356 00000 n Nitrogen applied in 3 equal splits (each at sowing, 25 and 40 days after sowing) gave significantly highest baby corn yield (1 517 kg/ha). Only parts of the nutrients in feeds are available for the animal. products of digestion. Other feeds, such as sugar beet pulp, brewers’ grains, and pineapple bran, are by-products that remain after a food crop has been processed for human use. Concentrates are the energy-rich grains and molasses, the protein- and energy-rich supplements and byproduct feeds, 0000014440 00000 n 0000001131 00000 n Types of fodder. Then, a post-slaughter analysis of the carcasses was conducted. 0000045212 00000 n Investments have involved firms that mostly have a footprint in South Africa. **Revised by S. LeValley, Extension sheep/youth specialist and assistant professor, animal sciences. Thus, the nutrient utilization and growth performance was significantly higher in animals fed on higher levels of green maize, which concluded mat crossbred heifers might be fed on higher levels of green fodder for better performance. Teagasc has an interactive calculator on the client site www.teagasc.ie where the price of barley and soya can be entered and the relative value of different feeds is then calculated automatically 2 34. the grain, fodder and fuel production serial-folds compared with sowing on fiat bed soil (control) in first as well as second harvest in first and second year (ratoon). The yields were higher in the ratoon crop than in the first-year crop. However, in addition to shortage of feed, it is well documented worldwide that imbalanced nutrition is a major factor responsible for low livestock productivity. 2. Roughages – Roughages are the feed stuffs which contain more than 18 percent crude fiber and … The tables below contain the average nutritional values of the usual components of homemade con-centrates as well as of roughage most commonly complemented with concentrated feeds. The major aim is to provide high quality protein. registered significant increase up to 200 kg N/ha. firms in both animal feed and poultry, with major investments (and plans) occurring from 2012 to 2015. 0000041941 00000 n Amongst the inorganic and organic nitrogen sources tested, soyabean meal and ficus fruits, in which nitrogen is present in complex form, were the best supplements in enhancing the in vitro dry matter digestibilities of the residues. 0000042148 00000 n 0000003072 00000 n The W31 and W33 geese had higher dressing percentages than the W11 line: 65.9%, 65.5% and 64.5%, respectively, as well as greater weights of eviscerated carcass, amounting to 4054 g, 4079 g and 3406 g, respectively.
