Standardised ileal digestibilities (SID) of crude protein and amino acids (AA) originating from 24 different feed ingredients, including 11 feed ingredients produced from soybeans, seven by-products of starch processing, four whey products and two fish meals, were determined in piglets by means of the difference method. For the indispensable AA, the highest SID values were obtained in three out...

Forty two Malpura lambs (21 d old) were divided into three groups of 14 each consisting of 8 females and 6 males. Lambs were allowed to suckle their respective dams twice daily up to weaning (13 wks) and offered free choice concentrate and roughage in a cafeteria system. The lambs in control group were fed conventional concentrate mixture, in RBO group concentrate mixture fortified with 4% indu...

cyclical, and is historically dependent on factors affecting world supply and demand for wheat as a human foodstuff. Wheat generally becomes economically feasible to feed when the price per bushel is 108–115% that of corn, as a result of higher bushel weight and protein concentration. This generalized value is somewhat of a “moving target” as numerous factors affect the ability to utilize wheat...

This paper summarises six studies undertaken by the Sheep CRC to elucidate certain aspects of confinement feeding of sheep. A review of confinement feeding highlighted the variability of growth rate and feed conversion of sheep and revealed that little is known about the use of sorghum for feeding sheep. The review indicated that the main factors responsible for variation of growth rate and fee...

Considerable savings can be realized and performance can be improved by formulating poultry feeds based on the daily feed intake and nutrient needs of the chicken. Programmes have been developed for commercial layers, broiler breeders, and replacement pullets for commercial egg production. Programmes have also been suggested for broiler breeder replacements for this purpose. Suggestions have be...

Feed related costs are the main drivers of profitability of commercial poultry farms, and good nutrition is mainly responsible for the exceptional growth rate responses of current poultry species. So far, most research on the poultry feeding behaviour addresses the productivity indices and birds’ physiological responses, but few studies have considered the biomechanical characteristics involved...

Male Holstein calves (n = 120) purchased from local dairy farms were fed one of three calf milk replacers for 42 d. Experimental milk replacers were formulated to contain whey protein concentrate (WPC) as the primary protein source or WPC plus 5% spray-dried bovine plasma (SDBP) or spray-dried porcine plasma (SDPP). The SDPP was heated to remove heat-insoluble materials and provide products wit...
