The paper presents the results of full-scale and experimental studies for applying a new design damping energy flow with lateral water intake. In article, method increasing efficiency intake calculation have been improved. proposed version according to method, compiled several assumptions, demonstrated possibility using such well damper high operational reliability aimed at structures. Recommen...

Two experiments were conducted to determine the effects of restricted feeding on performance, carcass characteristics, and composition. In Trial 1, 36 individually penned steer calves (280 +/- 13 kg BW) were fed all-concentrate diets at intake levels of ad libitum and 90 and 80% of ad libitum. Trial 2 used 36 individually penned steer calves (298 +/- 14 kg BW) fed corn silage-based growing diet...

A high concentrate diet was fed at 1.2, 1.5, 1.8 and 2.1% of body weight to four Angus steers (258 kg) equipped with cannulas in the proximal duodenum and distal ileum. As level of feed intake increased, flow of N, nonammonia N, microbial N and feed N to the small intestine increased linearly (P less than .05). Bypass of feed N increased from 44 to 71% of fed N. At the highest intake level, rum...

On a life-cycle basis, beef animals are able to consume large amounts of low-cost, low-quality forages relative to higher-cost concentrates compared with pigs and chickens. However, of the 3, beef is still more expensive to produce on a cost–per–edible pound basis. Accordingly, there is need for genetic programs and management changes that will improve efficiency, sustainability, and profitabil...

Fourteen trials were conducted to evaluate the effects of feeding monensin at 33 ppm alone, tylosin at 11 ppm alone and the two feed additives in combination on the average daily gain, average daily feed intake, feed:gain ratio and the incidence of liver abscesses in feedlot cattle. Monensin reduced feed intake and improved feed efficiency (P less than .05), and had no effect on average daily g...

The efficiency of producing salable products in the pork industry is largely determined by costs associated with feed and by the amount and quality of lean meat produced. The objectives of this paper were 1) to explore heritability and genetic correlations for growth, feed efficiency, and real-time ultrasound traits using both pedigree and marker information and 2) to assess accuracy of genomic...

The influence of rumen microbial structure and functions on host physiology remains poorly understood. This study aimed to investigate the interaction between the ruminal microflora and the host by correlating bacterial diversity with fermentation measurements and feed efficiency traits, including dry matter intake, feed conversion ratio, average daily gain, and residual feed intake, using cult...

in order to compare the effects of different weaning strategies on feed intake, structural growth measurement and health, blood metabolites and economic efficiency of young dairy calves, twenty four female holstein calves were used. calves after birth were randomly assigned into one of three weaning strategy as follow: 1) weaning based on feed intake, 2) weaning based on weight gain (30 kg weig...
