Untreated wheat straw (UWS) or ammoniated wheat straw without (AWS) or with (AWSP) a supplement of potato protein of a low rumen degradability was fed to three steers according to a 3 x 3 Latin square design. All rations were supplemented with sugar-beet pulp and minerals. Voluntary organic matter intake (OMI, g/kg0.75 per d) was 67.8, 76.0 and 80.1 for whole rations (51.1, 59.7 and 59.2 for st...

THREE experiments were conducted with broiler chicks to determine the minimum crude protein levels in diets of starters and finishers reared a tropical environment. The first two trials covered both starter finisher periods 12 weeks while third experiment only finishing period. calculated dietary used trial 14,16 18, 20, 22 24%; second trial, 22, 24 26% 14, 16, 18 20% on air dry basis. Results ...

The importance of protein quality for practical rations becomes evident as soon as an attempt is made to economize and to establish for such rations the lowest level of protein that will give efficient production. Woodman & Evans (195 I) demonstrated this point with pigs fed on a simplified barley-fine-bran ration. Supplementation with fish meal at the rate of 4.2% protein gave efficient produc...

Three broiler finishing rations with calculated metabolizable energy values (ME) of 3175, 3250, and 3325 kcal/kg and constant lysine and sulfur-bearing amino acid: energy ratios were evaluated at two environmental temperatures. Broiler chickens were reared from 3 to 7 weeks in either an 18.3 or 26.7 C temperature. At the 18.3 C temperature, 7-week body weights increased linearly 3.1% as energy ...

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...
