In order to determine of physical characteristics of rice straw as an effective source of fiber in ruminants, alfalfa hay, four varieties of rice straw (Taroum Neda, Taroum Neamat, Taroum Sangi, and Asgari), and four rations that contained four varieties of rice straws were investigated. The chemical (dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), nonfiber carbohydrates (N...

TODOROV, N., M. SIMEONOV AND A. KIRILOV, 2013. Feeding early-weaned lambs with pelleted dry distillers’ grain with solubles (DDGS) plus whole grain, and two methods of supplying minerals and vitamins. Bulg. J. Agric. Sci., 19: 810-816 The aim of the experiment is to examine possibilities to feed early-weaned lambs with pelleted DDGS, whole maize grain and alfalfa hay when minerals and vitamins ...

Two hundred ninety-nine crossbred yearling steers (363 +/- 15 kg initial BW) were fed for an average of 114 d in a finishing study comparing 7 diets in which steam-flaked corn was used as the principal energy source. Forty-nine pens were used in this study with 7 BW blocks, 7 pens per treatment, and 5 to 7 steers per pen. A control diet with no distillers grains with solubles (DGS) was compared...

An experiment was conducted to determine the effects of Cu supplementation on performance, subcutaneous adipose tissue mRNA expression of acetyl CoA carboxylase (ACC), stearoyl CoA desaturase (SCD), uncoupling protein 2 (UCP2), and leptin in growing and finishing steers. Forty-eight purebred Angus steers were allotted to one of five treatments: 1) control (no supplemental Cu); 2) 10 mg Cu/kg DM...

Two trials were performed in order to evaluate the effects of spirulina platensis (SP) supplemented (0, 0.5, and 1.0% diet DM) high-energy on nutrient digestion growth-performance feedlot cattle. The dose each treatment was top dressed mixed directly with basal at time feeding. In Trial 1, six cannulated Holstein steers (281±2 kg) used a replicated 3×3 Latin square experiment. Supplemental SP d...

This study was conducted to determine in vitro crude protein degradation (IVDP) parameters and effective crude protein degradability (EPD) of various feeds using the modified in vitro gas production (GP) technique. Feed samples were alfalfa hay, soybean meal, soybean, rapeseed meal, sunflower meal and fish meal. Rumen fluid was collected before the morning feeding from four rumen fistulated lam...

Three levels of dietary sulfur (.17, .22, and pens (6 head/pen). Pens were 43 m with 22 m overhead .27%, DM basis) were evaluated in an 84-d growing trial shade. The trial was initiated July 24, 1996. Steers were involving 108 crossbred steer calves (215 kg). Calves were implanted with Synovex-S® (Fort Dodge Animal Health, Fort blocked by weight and randomly assigned within weight Dodge, IA) up...

Probiotics are commonly fed to dairy cattle to improve feed efficiency and increase milk yield. The objective of this study was to determine the effects of a probiotic, (Bovamine®; Nutrition Physiology Company, LLC. Guymon, OK) consisting of Lactobacillus acidophilus (LA) and Propionibacterium freudenreichii (PF), on the in vitro digestibility of starch and neutral detergent fiber (NDF). Starch...

The increasing cost of feed supplements necessitates evaluation of alternatives for ruminant livestock grazing poor quality warm-season grasses. This study determined how supplementing bahiagrass hay (Paspalum notatum Flügge cv. Pensacola) with soybean [Glycine max (L.) Merr.] meal or warm-season legume hays affected intake, digestibility, and N utilization by lambs. Dorper x Katadhin crossbred...

A feedlot growth-performance trial and a metabolism trial were conducted to evaluate the interaction of forage level (10 vs 20%) and monensin (0 vs 28 mg/kg, air-dry basis) on utilization of a steam-flaked corn-based finishing diet. There were no treatment interactions (P > .10) on feedlot cattle growth performance or site and extent of digestion of OM, ADF, N, and starch. Monensin supplementat...
