Limit-feeding corn as an alternative to hay for gestating beef cows.
Three experiments were conducted to determine the efficacy of limit-feeding corn-based diets as an alternative to hay for beef cows in gestation and early lactation. Seventy or 71 mature, pregnant Simmental crossbred cows (average weight = 589 +/- 10 kg) were used in each trial. Each of 29 or 30 cows was fed approximately 5 kg of whole shelled corn, 1.2 kg of a pelletted supplement, and 1 kg of...
متن کاملReducing Losses When Feeding Hay to Beef Cattle
show that hay costs between $0.02 and $0.07 per pound of dry matter; usually more than double the cost for the same amount of nutrients from pasture. Hay is expensive because (1) it requires a large investment in equipment, (2) it requires labor to make and feed, and (3) more than 50 percent of it is wasted by either poor storage methods or improper feeding practices, or both (Figure 1). This g...

متن کاملTiming of feeding orchestrates circadian post-feeding intake rhythms in once-daily fed dairy cows
The objective was to establish effects of feed presentation time and dietary forage to concentrate ratio on circadian postprandial rhythms of feed intake in lactating cows. Four multiparous and four primiparous Holstein cows were fed in a 4 × 4 Latin square design (with a 2 × 2 factorial arrangement of treatments) a higher (HC, forage to concentrate ratio = 38.5:61.5) or a lower (LC, forage to ...
متن کاملSource and feeding level of nitrogen on growth and carcass characteristics of beef steers fed grass as hay or silage.
Sixty medium-framed Hereford steers averaging 243 kg were used in an experiment including a growing period (28 wk) and a finishing period ending when the animals had approximately 4 to 10 mm of fat thickness (Canadian grade A1). Steers were assigned randomly to a 2 x 3 factorial arrangement of treatments for 28 wk (growing period). From the end of the growing period until slaughter, all steers ...
