Feeding behavior changes of cattle during introduction of monensin with roughage or concentrate diets.
To assess the nature of the aversion frequently shown by cattle for feed containing Rumensin, cattle were prepared with rumen cannulas and adapted to either a 93% ground alfalfa hay diet (n=12) or an 85% concentrate diet (n=12) They were assigned to one of three treatments for 6 hr/day for 7 days: 1) Basal feed and continuous intraruminal injection of a total of 50 ml alcohol (Control); 2) 250 ...
متن کاملNet utilization of roughage and concentrate diets by sheep.
1. Two diets, an all-roughage diet and a high-concentrate diet, were fed at two levels, a low level of estimated 1-5 times maintenance energy requirement and a higher level of estimated two times maintenance energy requirement, to South African Mutton Merino castrated male sheep, aged 13 months and in fairly lean condition at the start of the 93 d experimental period. 2. Body composition and en...
متن کاملAd libitum vs. restricted fluid replacement on hydration and performance of military tasks.
INTRODUCTION The primary objective was to evaluate the effect of ad libitum vs. restricted fluid replacement protocol on hydration markers and performance in selected military tasks. The secondary objective was to determine if 300 ml x h(-1) could be considered a safe minimum fluid intake under the experimental conditions. METHODS Data were collected simulating a route march over 16 km. There...
متن کاملEnergy efficiency of growing ram lambs fed concentrate-based diets with different roughage sources.
Poor-quality roughages are widely used as fiber sources in concentrate-based diets for ruminants. Because roughage quality is associated with the efficiency of energy use in forage-based diets, the objective of this study was to determine whether differing the roughage source in concentrate-based diets could change the energy requirements of growing lambs. Eighty-four 1/2 Dorper × 1/2 Santa Inê...
متن کاملEffects of restricted and ad libitum intake of diets containing wheat middlings on site and extent of digestion in steers.
A 5 x 5 Latin square design was used to determine the effects of restricted and ad libitum intake of diets containing wheat middlings on the site and extent of digestion compared to ad libitum intake of a corn-based diet and ad libitum intake of chopped alfalfa hay. Five ruminally and duodenally cannulated Angus steers (519 +/- 41.5 kg BW) were used to compare five dietary treatments. The five ...
