“…Rearing systems of broiler chickens are crucial to influence their welfare, health, and production efficiency especially under heat stress conditions. Heat stress has strong and immediate impacts on the welfare and performance of birds ( Alagawany et al., 2017 , El-Kholy et al., 2017 , El-Kholy et al., 2018 , Farghly et al., 2018a , Farghly et al., 2018b , Farghly et al., 2018c , Abd El-Hack et al., 2019a ), and these adverse effects are strongly influenced by interfering with different European broiler g and rearing systems. Floor constructions greatly contribute to heat gain or loss in summer and its effect is usually ignored.…”

The effects of different rearing systems ( RS ) including cage rearing systems ( CRS ), litter rearing systems ( LRS ), and perforated plastic slate rearing systems ( PSRS ) on the productive performance, carcass traits, blood hematological and biochemical parameters, and humoral immunity in broiler chickens exposed to heat stress were investigated. A total of 270 1-day-old Avian 48 chicks were randomly assigned to 3 groups equally, each was divided into 9 replicates (each of 10 birds) housed in studied RS. Results revealed that CRS had higher ( P < 0.001) body weight and weight gain at all experimental periods (except in the sixth wk for weight gain) followed by LRS. Birds housed in PSRS consumed lower ( P < 0.001) feed than those in CRS (during the fourth to sixth and overall periods) and LRS (during all experimental periods except the second one). Best values of feed conversion ratio and European broiler index were shown in CR birds. All carcass traits were not altered by different RS except the percentages of dressing, liver, breast, and left filet, which were elevated ( P < 0.05) in caged birds. Eosinophil, lymphocyte, basophil, and monocyte counts and phagocytic index and activity were reduced ( P < 0.05 or P < 0.01) in LRS. Humoral immune response against the Newcastle disease virus and avian influenza were not differed. Birds in LRS showed higher ( P < 0.05) serum cholesterol, uric acid, and lactate dehydrogenase as well as liver and muscle cholesterol contents. Lipid peroxidation was reduced ( P < 0.05) in the LRS and PSRS groups, whereas superoxide dismutase was elevated ( P < 0.05) in CRS and LRS. Thus, CRS and LRS were preferred for better growth performance and carcass traits of heat-stressed broilers, whereas CRS and PSRS were better in reducing tissue cholesterol under the conditions of our study.

“…Moreover, they do not need a high proportion of protein in their feed, in contrast to the other poultry species. Ducks live happily under a wide range of climatic conditions and they are free from common poultry diseases, such as leucosis, Marek's disease, infectious bronchitis and other respiratory troubles [1][2][3][4][5]. The duck, as a waterfowl, has a different physiology than the other poultry types, where their breast muscles have a higher red-fiber content than chickens [6], and so are considered as a red meat source.…”

The present study aimed to investigate the effect of different housing systems on Pekin ducks. A total of 300-day old Pekin ducklings were randomly divided into four experimental groups; the first housed in a closed house (CH), the second in closed house with open yard (HY), the third group in closed house with swimming pool (CHSP) and the fourth in a closed house with swimming pool and yard (HYSP). Results indicated that the HYSP and CHSP produced higher body weight comparing to the other groups. However, the HYSP gave the highest body weight followed by CHSP then HY and CH. The same trend was observed regarding weight gain and feed-conversion ratio (FCR). Moreover, HYSP, HY and CHSP showed higher dressing percentage, breast muscles and thighs and lower abdominal fat than the CH group. Serum protein was significantly higher in HYSP and HY than that of the closed house. While, lipids, cholesterol and triacylglycerol were significantly lower in groups housed in HY than that of CH. Meat cholesterol and triacylglycerol reduced in groups reared in HY. Housing ducklings in yards and using swimming pools significantly improved the general immunity (phagocytic index and activity and differential leucocytes count), and also improved the oxidative stress parameters. In conclusion, results confirmed that housing ducks in a house supplied with yard and swimming pool can improve its productivity, carcass traits, meat quality, blood lipid profile, immunity and antioxidative status.

“…Feed restriction is used to retard growth performance of fast growing birds, in particular, in alternative systems of production, which require long growth phases (Govaerts et al, 2000;Jahanpour et al, 2015;Nielsen, Litherland, & Noddegaard, 2003;Soltanmoradi et al, 2014). Nutritionists and researchers have reported that in broilers, physical feed restriction for a short time at an early age decreases abdominal fat, improved growth, and feed efficiency; furthermore, the performance of birds in restricted and unrestricted groups is similar at marketing age (Farghly, Abd El-Hack, Alagawany, Saadeldin, & Swelum, 2018a;Farghly Alagawany & Abd El-Hack, 2018b;Naji, Al-Ani, Manati, & Mukhlis, 2003). Other research shows no significant difference in the body gain in growing quails fed on a 10% feed restriction basis, and an ad libitum basis (Buragohain, 2013).…”

The objective of this study was to evaluate the effects of quantitative feed restriction, along with dietary supplementation with a probiotic blend (Protexin) as a natural growth promoter, on the performance, water consumption, mortality rate and carcass traits of meat‐type quails. A total of 250 1‐day unsexed quails were randomly allocated to five equal groups in a completely randomized design. The first group (A) fed a basal diet without any restriction (24 hr/day); the second group (B1) fed the basal diet for 20 hr/day; the third group (B2) fed the basal diet enriched with probiotic (0.1 g/kg diet) for 20 hr/day; the fourth group (C1) fed the basal diet for 16 hr/day; and the fifth group (C2) fed the basal diet enriched with probiotic (0.1 g/kg diet) for 16 hr/day. Birds were fed ad‐libitum from 0–14 days of age, and then the feed restriction regimes started from 14 till 28 days of age. Results showed that quails in the control‐group consumed more feed and water than the other treatment groups (p < .01), however their body weights did not differ (p > .05) compared with the other treated groups. The best feed conversion values were achieved in quails supplemented with probiotic blend (B2 and C2) in comparison with the other groups (p < .01). Feeding probiotic had a positive effect on bird health which reduced the mortality rate. Further, mortality rate was significantly reduced (p < .05) by feed restriction, with or without probiotic supplementation. No carcass parameters were significantly affected (p > .05) by treatments. Our results show that quail could be reared under a feed restriction system, for 4–8 hr daily, along with dietary supplementation of probiotic as growth promoter for better growth performance.
