This study was conducted to investigate the effects of different levels of zinc sulfate and chromium picolinate on the performance, immune response and meat quality of Japanese quails under heat stress condition. The birds (n = 540; 7-d-old) were randomly assigned to 9 treatment groups consisting of 3 replicates of 20 birds each in a 3 × 3 factorial arrangement of treatments [zinc (0, 40, 80 mg...

an experiment was conducted on 400 broilers to evaluate the effects of dietary supplementation ofantibiotic and probiotic on performance of birds under heat stress condition. the first group of chickens, thecontrol group, received a diet without any antibiotic and probiotic. the second group received diet with0.02% virginiamycin antibiotic; the two other groups were fed diets with 0.05% and 0.1...

This study investigated the effects of dietary supplementation with Bacillus amyloliquefaciens D1 (B. D1) on growth performance, serum anti-inflammatory cytokines, and intestinal microbiota composition diversity in bearded chickens. To investigate amyloliquefaciensa fermented soy milk, 7-day-old broilers were orally fed different doses milk for 35 days, unfermented group as Placebo group. found...

Two iolinid predatory mites were studied in the laboratory as potential biological control agents of tomato russet mite, Aculops lycopersici (Acari: Eriophyidae). The development, reproduction and predation capacity Pronematus ubiquitus Homeopronematus anconai Iolinidae) on A. investigated. Developmental time from egg to adult at 25 °C averaged 9.59, 9.31 9.52 days for P. lycopersici, Typha ang...

The objective of this study was to test the hypothesis that reducing dietary CP by 1.5% and supplementing crystalline AA (CAA) to meet the standardized ileal digestible (SID) AA requirements for growing and finishing pigs decreases air emissions of ammonia (NH), nitrous oxide (NO), and carbon dioxide (CO) compared with an industry standard diet, without reducing growth performance. Seventy-two ...
