Forty-eight (32.8 ± 2.9 kg BW) were enrolled in current study. period has been divided into three stages; early (DIM less than 80 days), Mid 80-140 Late over 140 days). had decreased daily-MY at a rate 18.4% 31.9% mid late stages lactation, compared with stage, respectively (p = 0.001). Furthermore, lactose%...

Climate change is considered to be the primary cause of heat stress (HS) in broiler chickens. Owing unique properties extracted polyphenols, resveratrol-loaded liposomal nanoparticles (Resv-Lipo NPs) were first explored mitigate harmful effects HS. The dietary role Resv-Lipo NPs heat-stressed birds was investigated based on their growth performance, antioxidative potential, and expression shock proteins, sirtuins, antioxidant, immune, muscle-building related genes. A total 250 1-day-old Ross...

Abstract Background This study was conducted to estimate the impacts of using varied feeding regimens with or without protease supplementation on growth performance, apparent amino acid ileal digestibility (AID%), economic efficiency, intestinal histology, and blood biochemical parameters broiler chickens. Three hundred one-day-old chicks (Ross 308 broiler) were randomly allotted a 3 × 2 factorial design. The experimental design consisted three regimens; FR1: recommended protein SBM diet,...

Nutritional interventions with natural antioxidants can provide a pragmatic solution for modifying hens' performance and maintaining oxidative stability of eggs during storage. Quercetin is the most abundant flavonoids potent antioxidant immune stimulant activities. The concept incorporating quercetin, as immunostimulant, into effective nano-carriers (QNPs) has promoted their bioavailability thus, effectiveness first time were assessed on laying immunity, quality Four hundred 12-weeks-old...

The thermal environment is a major factor that can negatively affect milk production and health traits of dairy cows. objective this study was to assess the pure Holstein (HO), Brown Swiss (BS), first generation crossbred (BH) backcross (BC) cows under subtropical Egyptian conditions, in addition investigating impact temperature–humidity index (THI) on traits. Pure HO, BH BC had significantly higher 305-milk yield (MY) (9145, 8914 9021 kg, respectively), total-MY (10 694, 9845 10 118 than...

This study aimed to reconnoiter breed variations in productivity, traits of carcass, economic rate, and IGF-1 gene regulation for meat production among Pekin, Muscovy, Mulard ducks. A 10-week trial was conducted, using 120 ducklings (2-week old) that were divided into three groups based on breed. Each kept a separate group, four replicates 10 birds each. Muscovy ducks exhibited superior body weight, weight gain, feed conversion ratio, dressing breast percentage compared the other breeds...
