Abstract The use of modern chicken genotypes with high egg or meat performance results in the ethically unacceptable practice culling day-old male layer chicks because their inefficient fattening performance. Dual-purpose a balanced profile for both eggs and are one option to avoid this practice. In study, four crosses breed (White Rock New Hampshire) Bresse Gauloise were compared under conditi...

The aim of the present study was to investigate the relationships between temperament score and blood cortisol concentration, as well as energy metabolic parameters (glucose, triglyceride, non-esterified fatty acid and cholesterol) in Tsigai lambs during fattening. The temperament of lambs was assessed (scored) by a temperament score test, where the behaviour of animals was evaluated in a 5-sco...

The pharmacokinetics of trimethoprim-sulfamethoxazole were studied in 12 healthy adult subjects receiving trimethoprim at 20 mg/kg of body weight per day and sulfamethoxazole at 100 mg/kg/day, which is the conventional dose for treating Pneumocystis carinii pneumonia (PCP). Daily doses were evenly divided and orally administered every 6 h for 3 days. Trimethoprim, sulfamethoxazole, and N4-acety...

Forty-four merino lambs (6 to 8 wk old; BW 15.6 ± 0.21 kg) were used to study the effect of adding different proportions of sunflower soap stock (SS) to pelleted total mixed ration (TMR) for fattening lambs on feed intake, animal growth and dressing percentage, ruminal fluid characteristics, and blood acid-base parameters. Lambs were assigned to 1 of 4 experimental groups (11 lambs per group), ...

The present study explored whether the use of group medication with antibiotics in a Danish pig herd was reduced after vaccination of the pigs against proliferative enteropathy (PE) caused by Lawsonia intracellularis. 7900 pigs originating from a single commercial sow herd were vaccinated against L. intracellularis, whereas 7756 pigs were kept as non-vaccinated controls. The pigs were included ...

The article presents data on the effect of phytobiotic additive “Activo” at a dose 0.2 g/kg feed piglets live weight growing and finishing fattening periods. average daily gain consumption per 1 kg were determined during experiment. Among biochemical parameters it was level total proteins, protein fractions (albumin globulins), calcium inorganic phosphorus. morphological in blood both periods d...

Objective: By investigating the effects of feeding Enterococcus faecalis FK-23 preparation to Japanese Black cattle in the late fattening period, this paper discusses the increased value of beef and the feasibility. Method: 10 beef cattle were grouped into the Test Group and the Control Group, 5 beef cattle in the Test Group were fed E. faecalis FK-23 preparation at 8.0 g per day per head. The ...

This study was conducted to evaluate the effect of medicinal plant by-products (MPB) supplementation to a total mixed ration (TMR) on growth, carcass characteristics and economic efficacy in the late fattening period of Hanwoo steers. Twenty seven steers (body weight [BW], 573±57 kg) were assigned to 3 treatment groups so that each treatment based on BW contained 9 animals. All groups received ...

However, the amount of fat deposited prior to departure is variable depending on individual migration strategies. Despite their small size and high massspecific metabolic rates, migratory hummingbirds at isolated meadows can fatten up to 44% in...
