Eighty Angus and Angus x Simmental steer calves were used in a completely random design to determine the effect of rate of BW gain during the backgrounding period on subsequent feedlot performance, carcass characteristics, Warner-Bratzler shear force (WBSF), and sensory analysis. Animals were stratified by BW and allotted randomly to 1 of 10 pens (5 pens/treatment). Dietary treatments were form...

The objective of this study was to investigate the effects of tallow and choice white grease (CWG) fed at 0, 2, and 4% of the diet dry matter (DM) on rumen fermentation and performance of dairy cows when corn silage is the sole forage source. Fifteen midlactation Holstein cows were used in a replicated 5 x 5 Latin square design with 21-d periods. Treatments were 0% fat (control), 2% tallow, 2% ...

Predicting animal performance and relating it to improvements in corn silage quality whether from breeding or management is complex. In numerous studies, differences in fiber and digestibility translate into differences in animal performance. For example, researchers in Idaho have found that high quality corn silage (low fiber and high digestibility) produced $315 more beef per acre than low qu...

Three studies were conducted to evaluate the effects of dried distillers grains with solubles (DDGS) on feed intake in growing pigs. In all experiments, pigs were housed in 10.5 × 10.3 ft pens with four 1-hole feeders in each pen to allow pigs to choose from four dietary treatments. In Experiment 1, we evaluated the influence of DDGS drying method on palatability of DDGS. Diets were a control c...

Two trials were conducted to determine the NE value of ensiled wet corn gluten feed (WCGF) in corn silage finishing diets for beef cattle. In Trial 1, 96 Angus-crossbred yearling steers were fed corn silage-based diets containing 0, 20, 40, or 60% ensiled WCGF. Increased dietary WCGF resulted in improved DMI (linear, P less than .05), ADG (linear; P less than .05), and feed/gain (linear, P less...

The objectives of these experiments were to examine whether N retention and feedlot performance by steers administered estradiol 17-beta (E2) alone (metabolism study) or in combination with trenbolone acetate (TAB; feedlot study) could be enhanced by increasing dietary ruminal escape protein. For the metabolism study, 16 Angus steers (average weight = 308 +/- 5 kg) were used in a randomized blo...

This study aimed to investigate the effect of supplementation with a mixture molasses and condensed fermentation solubles (M-CMS) in different synchronization diets formulated forage sources an attempt improve efficiency by M-CMS. In first experiment, three levels M-CMS (N: 0%; L: 1.75%; H: 3.50%) were supplied or without corn silage evaluate on diet synchrony index (SI) 0.80. second containing...

Twelve lactating Holstein cows were utilized in a repeated switchback design to evaluate milk production and milk fat composition responses to wet corn distillers grains. Total mixed diets consisted of 31.4% corn silage, 18.4% alfalfa hay, and either 50.2% of a concentrate mix that contained mostly corn and soybean meal or 19.4% of a concentrate mix that contained mostly corn and 31.2% wet corn...

A combined deficiency of vitamin A and E was diagnosed in finisher cattle in a 12,000 head feedlot producing beef for the Japanese market. It was estimated that approximately 2,000 cattle were affected at any one time (i,eu cattle between 220 and 300 days in the feedlot).The diet was based on grain and corn silage and although each animal had been injected with l,000,000IU vitamin A and 1OOIU v...
