Energy levels for growing and finishing steers

Protein and selenium levels for growing and finishing beef cattle.

Two feedlot studies were conducted with 96 Hereford steers to assess the relationship be:ween selenium adequacy and protein requirements of growing and finishing cattle. The first study was a 98-day growing trial with feeder steers as they gained from 230 to 340 kilograms. Diets contained 55% corn silage (dry matter basis) with shelled corn and were supplemented with soybean meal and sodium sel...

Growing and finishing performance of steers when fed recycled poultry bedding during the growing period.

Sixty Angus-cross steers were used to compare the effects of recycled poultry bedding (RPB) stacking method and the inclusion of monensin in growing diets on performance. Steers were individually fed balanced, growing diets for a period of 84 d. The diets were control (CON), CON + monensin (CON+M), deep-stacked RPB (DS), DS+M, shallow-stacked RPB (SS), and SS+M. The CON diets contained corn, so...

Comparison of models for estimating methane emission factor for enteric fermentation of growing-finishing Hanwoo steers

The methodology provided by the Intergovernmental Panel on Climate Change (IPCC) guidelines is widely used for estimating enteric methane (CH4) production by cattle. No attempt other than the default values in the IPCC Tier 1 has been made for estimating CH4 emission from Hanwoo, a dominant beef species in Korea raised in a unique feeding system. The objective of this study was to compare model...

Studies on Feeding Wheat Middlings to Beef Heifers and Growing and Finishing Beef Steers

INTRODUCTION The type and amount of concentrate included in beef cattle diets can greatly influence production and profitability. Small grains are typically fed in these rations, but the inclusion of by-product feeds, such as wheat middlings (WM), in growing and finishing diets have recently been studied (Dalke et al., 1997; Blasi et al., 1998). Wheat middlings are the by-product of the wheat m...
