14. Effects of Glutamine on Digestive Function and Redox Regulation in the Intestines of Broiler Chickens Challenged with Salmonella Enteritidis
ABSTRACT The aim was to investigate the effect of glutamine (Gln) on broilers challenged with Salmonella Enteritidis. 240 1-day-old birds were divided into four groups in a completely randomized design, each of which included 6 replicates with 10 birds per replicate. Group I served as the unchallenged, untreated control (CON). All birds in groups II (SCC) -

18. Effect of Exogenous Protease, Mannanase, and Xylanase Supplementation in Corn and High Protein Corn DDGS Based Diets on Growth Performance, Intestinal Morphology and Nutrient Digestibility in Broiler Chickens
ABSTRACT A study was conducted to evaluate the effects of exogenous enzymes supplementation in high protein (Hi-Pro) corn DDGS-based diets on broiler growth performance, intestinal health, and nutrient digestibility. A total of 200 one-day-old broiler chicks were randomly allocated to four dietary treatments with five replicates of 10 birds each. A basal die

19. Requirement of Digestible Methionine + Cystine to Molted Laying Hens
ABSTRACT The present study aimed to determine the ideal requirement of digestible methionine + cystine to molted laying hens. The experimental period lasted 105 days, divided into five periods of 21 days. 144 Hisex White laying hens with 84 weeks-of-age were used. The experimental design was completely randomized with treatments constituted for six levels of

20. Optimal Available Phosphorus Levels in Diets Containing Different Dicalcium Phosphate Particle Sizes for Japanese Quails
ABSTRACT This experiment was conducted to investigate the effects available phosphorus levels and dicalcium phosphate particle size on the live performance, and egg parameters and bone parameters of Japanese quails in lay. The experimental diets were based on corn and soybean meal and formulated to contain 2900 kcal metabolizable energy (ME)kg-1, 200 g kg-1

23. Comparison of the Dietary Supplementation of Lactobacillus plantarum, and Fermented and Non-Fermented Artemisia Annua on the Performance, Egg Quality, Serum Cholesterol, and Eggyolk-Oxidative Stability During Storage in Laying Hens
ABSTRACT Artemisia annua L. is a widely distributed medicinal plant and well-known for treating malaria due to the artemisinin content. We previously found enhanced antioxidant and antibacterial activities of Lactobacillus plantarum-fermented A. annua dried leaves in vitro. The present study compared the effects of the dietary supplementation of L. plantarum

24. Effect of Photoperiod on the Egg Production, Plasma Luteinizing Hormone, Follicle-Stimulating Hormone, Gonadal Hormones, and Mrna Levels of Lh and Fsh in the Hypothalamic-Pituitary-Gonadal Axis of Pigeons
ABSTRACT We investigated the egg production, changes in luteinizing hormone (LH), follicle-stimulating hormone (FSH), gonadal hormones, and their mRNA levels in the hypothalamic-pituitary-gonadal axis of White King pigeons submitted to different photoperiods. The treatments consisted of three photoperiods (8 h light (L):16 h dark (D), 12L:12D, and 16L:8D), w
