Meal Feeding and Broiler Performance
Poultry Science, 1986 Abstract Male broiler chickens were meal fed using 3.5 hr on:4.5 hr off, 3 cycles/24 hr and in combination with 2 hr on:2 hr off, 6 cycles/24 hr; comparison was made to ad libitum feeding, all with continuous light. Trials were conducted at optimum (21 C) grow-out temperature and at hot (22 to 33 C) grow-out temperatures.

Significance of chick quality score in broiler production
Animal, 2012 The quality of day old chicks is crucial for profitable broiler production, but a difficult trait to define. In research, both qualitative and quantitative measures are used with variable predictive value for subsequent performance. In hatchery practice,

Modeling the performance of broilers under heat stress
Poultry Science, 2021 A meta-analysis was developed to model performance depression in heat stress (HS), to analyze the influence of HS type (cyclic or constant), and to assess the correlation between dietary electrolyte balance (DEB) and HS in broilers. Two databases (Dat) with performance and temperature were constructed (initial phase - up to 21 d of age - 14 articles, 7,

Effect of Dietary Beta-Glucan on the Performance of Broilers and the Quality of Broiler Breast Meat [PDF]
Asian-Australasian Journal of Animal Sciences, 2016 A total of 400, one day-old commercial broiler chicks were divided into five diet groups (negative control, positive control group with 55 ppm Zn-bacitracin, 15 ppm β-glucan, 30 ppm β-glucan, and 60 ppm β-glucan) and fed for six weeks. Ten broilers were allotted to each of 40 floor pens.

The Effects of Santoquin on the Performance of Broilers
Poultry Science, 1960 Abstract THE use of antioxidants in broiler feeds, in an effort to improve xanthophyll utilization, has produced conflicting results. Wilgus (1954), Potter et al. (1956) and Fritz et al. (1957) reported that the addition of DPPD (diphenyl-p-phenylenediamine) to the feed resulted in an increased deposition of yellow pigment in the skin and shanks of ...

Effects of incubation temperature pattern on broiler performance
Poultry Science, 2020 During incubation, development of embryos is affected by eggshell temperature (EST). A constant EST of 37.8°C has been considered so far to result in most optimal embryo development. However, it can be hypothesized that a higher EST in week 2 in combination with a lower EST in week 3 stimulates embryo development and subsequent grow-out performance. In
