Differences in producing performance and organoleptic meat characteristics among pig genotypes and/or types are widely known. These parameters also subjected to the animal’s development, feeding management. Detailed knowledge of effects production phase (PP), type (PT), dietary protein availability their interactions on nutrient digestibility, nitrogen balance metabolism is essential informatio...

Riparian habitat makes up a small fraction of the landscape but provides important stopover habitat for migratory birds. Hydroelectric dam operations cause fluctuations in water levels that can change the amount or quality of riparian habitat, which in turn might affect potential fattening rates of migrant birds. Here we used plasma metabolite analysis to estimate variation in fattening rate in...

On-farm practices like premature weaning and frequent regrouping induce stress to pigs. Early socialization or environmental enrichment in piglets reduce stress, as suggested previous studies. Little research with both effects commercial settings was found. The aim investigate the of preweaning on life-long performance 661 Danbred Two treatments were distinguished during suckling period: contro...

The growth-promoting effects of two dietary acidifiers based on formic acid were studied with 320 fattening pigs from ca 2 kg to ca 05 kg of body weight. The sorbate-coated formic acid contained formic acid and ammonium formate which were absorbed in diatomaceous earth and coated with potassium sorbate. The investigated liquid blend contained formic and lactic acids as the major components. The...

Antimicrobial resistance of Escherichia coli to modern beta-lactam antibiotics due to the production of extended-spectrum beta-lactamases (ESBL) and/or plasmid-mediated AmpC beta-lactamases (AmpC) represents an emerging and increasing resistance problem that dramatically limits therapeutic options in both human and veterinary medicine. The presence of ESBL/AmpC genes in commensal E. coli from f...

The main aim of the present work was to find out whether intensive fattening of pheasant poults can provide high-quality pheasant meat. The study is a pilot work in this area because until now pheasant rearing has only produced pheasants for the purpose of hunting. In this experiment three feeding mixtures were designed; nutritional and energetic composition of the mixtures complied with the re...

effect of two fattening systems were studied on feedlot performance and carcass characteristics of using of 66 fars native male kids in different ages. six kids were slaughtered at the first day of experiment and sixty kids were divided into two groups. the first group were kept in feedlot in individual pens and the second group grazed on rangeland, and after 3 months, were kept in feedlot in i...

To establish which factors influence performance and bird welfare during a fattening period and to identify those factors to be investigated during routine monitoring of farms by veterinary authorities, a questionnaire-based field study was conducted in districts of Lower Saxony, Germany, with the highest density of broiler chickens. Mortality and BW of farms with different stocking densities (...

To be able to analyze the relationship between the level of resistance and the use of antimicrobials, it is necessary to collect detailed data on antimicrobial usage. For this reason, data on antimicrobial use on 495 pig farms from entire Germany were collected and analyzed. In Germany, each application and dispensing of medicines to food-producing animals is documented in detail obligatorily b...
