the effect of daily oral administration of ephedrine (0, 1, 2, 4 or 8 mg kg-1 w0.75) on carcasscharacteristics of forty-four 2 yr old crossbred (mehraban x ghezel) fat-tailed ewes was studied. theewes were fed a fattening ration, and received ephedrine by using a drenching gun for either 50 or 70days. there was a significant interaction (p

It was assumed that the industry of beef cattle breeding being created in Krasnodar Territory would meet needs population beef. Due to fact there are not enough cattle, dairy bulls raised and fattened. Positive results obtained case when, along with an increase number fattened livestock animals, their intensive rearing feeding is introduced. In our studies, fattening Holstein Black-and-White bu...

We investigated patterns of seasonal variation in body weight in six populations of five resident species of temperate-zone woodpeckers: Acorn Woodpecker (Melanerpes formicivorus), Red-bellied Woodpecker (M. carolinus), Red-cockaded Woodpecker (Picoides borealis), Downy Woodpecker (P. pubescens), and Great Spotted Woodpecker (Dendrocopos major). After controlling for time of day and overall bod...

This paper discusses the outcomes of production experiment carried out on one poultry farms in Sverdlovsk Region and at departments Ural State Agricultural University. The was cross Ross-308 broiler chickens number 80 female male with an average live weight 43 g. During research, were housed different cages; continued throughout entire rearing period - 38 days. control group formed comparable f...

To determine the magnitude of the thermogenic response to a massive long-term overfeeding, an energy-balance study was carried out in nine lean, young Cameroonian men participating in a traditional fattening session: the Guru Walla. Food intake, body weight, body composition, activity, and metabolic rates were recorded during a 10-d baseline period and over the 61-65 d of fattening. Total energ...

This study explores administration of two piglet vaccines as compared to the mono- and adjuvant-application. A vaccine against the Porcine Circovirus Type 2 (PCV2) cap protein subunit and a vaccine with attenuated live culture against Lawsonia (L.) intracellularis were applied to piglets aged 23.5 days on average. 1'405 animals were divided randomly into four groups. One piglet group was immuni...

Two experiments were conducted to determine the nutrient composition, in vitro ruminal ammonia concentrations and pH of wet distillers grains (WDG, produced from tapioca 70% and rice 30%) and to evaluate dietary effects of fermented total mixed ration (TMR) using WDG on the performance, blood metabolites and carcass characteristics of Hanwoo steers from mid fattening to slaughter. In Exp. I, av...

Different possibilities to reduce the feed conversion ratio (FCR) both in fatteners and females are discussed. The dietary factor having the largest impact on the FCR in fatteners is the energy concentration. Within practical margins, an increase with 0.5 MJ DE/kg leads to a decrease of the FCR with 0.15-0.20 points. The fibrous rabbit diets can be made more energy dense by using fat or oil ric...
