Phenotypic and genetic relationships among feeding behavior traits, feed intake, and residual feed intake in steers fed grower and finisher diets.
Data from a 3-yr feeding trial of crossbred steers (n = 331) were used to examine the relationship between feeding behavior traits and feed efficiency in steers fed grower and finisher diets, successively. There were 2 feeding periods each year whereby the steers were fed a grower diet in the first feeding period (P1) and a finisher diet in the second feeding period (P2). Each feeding period la...
متن کاملExtended Grazing and Byproduct Diets in Beef Growing Finishing Systems
Sixty-three cross-bred lambs were randomly assigned to one of seven treatments according to a 2 × 3 + 1 factorial design (Table 1). There were two byproduct diets: one, a wet corn gluten feed which is a blend of 1/3 steep liquor/distiller solubles and 2/3 corn bran; and the second diet, where onehalf of the corn bran was replaced with wheat midds. Steep liquor/distiller solubles remained consta...
متن کاملEffects of timing and duration of test period and diet type on intake and feed efficiency of Charolais-sired cattle.
Objectives of this experiment were to: 1) determine appropriate test length, timing, and repeatability of DMI, ADG, and efficiency over different biological time points; 2) determine the efficacy of using decoupled performance and intake data to generate accurate feed efficiency measures; and 3) determine the relationship between forage-and grain-feed efficiency measures. Over 2 yr, Charolais c...
متن کاملStudies 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...
متن کاملGrowing 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...
