Supplementation of ammoniated wheat straw in wintering diets of gestating beef cows

Wheat Middling Versus Alfalfa Hay Supplements for Lactating Beef Cows Wintered on Ammoniated Wheat Straw

Protein supplementation of ammoniated wheat straw: effect on performance and forage utilization of beef cattle.

We studied the effects of supplement CP concentration on performance and forage use of cattle allowed ad libitum access to ammoniated wheat straw. During two consecutive winters, crossbred beef cows in late gestation (n = 87 in 1990-1991, n = 84 in 1991-1992) were used in a randomized complete block design with three pens per treatment. Cows were stratified by weight, body condition score (BCS)...

Protein Supplementation of Ammoniated Roughages. II. Wheat Straw Supplemented with Alfalfa, Blood Meal or Soybean Meal Fed to Wintering Steers

Two winter steer growth trials were conducted to investigate responses of steer calves to ammoniation of wheat straw, level of alfalfa haylage (50 or 66.7% of diet) and source of supplemental protein, soybean meal (SBM), blood meal (BM), or a blood meal-urea mixture (BM-U). In trial 1, the main effect of arnmoniation significantly increased average daily gain (ADG) from .15 t o .24 kgld, dry ma...

Magnesium for Gestating Beef Cows

T HREE experiments were conducted with eight gestating Angus cows to study the effects of feeding different magnesium levels at 145,200 and 255 days gestation. Each trial consisted of a S-day adjustment period and a 10-day experimental period. The average daily magnesium intake for the cows fed the basal ration was 3.4 grams. Supplemental magnesium was added at levels of 0, 4.1, 8.2 and 16.4 g ...

Supplementation of apple pomace with nonprotein nitrogen for gestating beef cows. IV. Pesticide accumulation in cows.

Samples of fresh apple pomace were collected from 14 loads of apple pomace as delivered from the processing plant in October 1968 and from stored apple pomace that had been obtained in October 1967 and fed during a feeding trial from mid-November 1967 through April 1968. All samples were analyzed for dicofol (kelthane), tetradifon (tedion), DDT, DDD and DDE. For the pesticide residues in fresh ...
