Spread of hatch and delayed feed access affect post hatch performance of female broiler chicks up to day 5.
It is not rare that newly hatched chicks remain without feed for about 24 to 48 h before they are placed on farms due to a series of logistic operations. Furthermore, the spread in hatching time can also mount up to 30 to 48 h for late v. early hatchers. In other words, the practice is a complex combination of spread of hatch and delayed feed access. The present study was aimed to investigate t...
متن کاملEnergetics, Mortality, and Body Mass Change of Breeder Chicks Subjected to Different Post-hatch Feed Dosages
Newly hatched leghorn breeder chicks (averaging 38.5 g body mass) housed in shipping containers were subjected to four limited feeding regimens for a three-day (3-d) period. The chicks were then raised for five days with adlibitum access to feed and nipple drinkers. For the 3-d treatment, the chicks received an average of 2.0, 2.5, 3.0, or 3.5 g starter feed (20.5% protein and 12,754 kJ/kg ME) ...
متن کاملInfluence of Different Dietary Levels of Energy and Protein on Reproductive and Post Hatch Growth Performance in Japanese Quails
The response of laying Japanese quails to dietary levels of energy and protein on performance, egg quality, hatchability, fertility and their effect on subsequent offspring live body weight was investigated. A total of 432 Japanese quails (13 weeks old) were divided into nine treatments. Each treatment comprised of four replicates of twelve birds (9 females and 3 males). Nine diets including th...
متن کاملPost-hatch heat warms adult beaks: irreversible physiological plasticity in Japanese quail.
Across taxa, the early rearing environment contributes to adult morphological and physiological variation. For example, in birds, environmental temperature plays a key role in shaping bill size and clinal trends across latitudinal/thermal gradients. Such patterns support the role of the bill as a thermal window and in thermal balance. It remains unknown whether bill size and thermal function ar...
متن کاملPerformance Analysis of Position-Domain Hatch Filter
Motivated both by the efficiency of the Hatch gain compared to the Kalman-type gain and the advantage of position-domain filtering compared to range-domain filtering, this paper proposes a position-domain Hatch filter for differential kinematic satellite-based positioning. A theoretically rigorous proof is provided to show that the Hatch gain generates a white residual sequence and is more effi...
