High-fibre pelleted rations decrease water intake but do not improve physiological indexes of welfare in food-restricted female broiler breeders

Autor: P.M. Hocking

Publikováno v: British Poultry Science. 47:19-23

1. A 3x2 factorial experiment was conducted with three diets and two lines of broiler breeder females to evaluate the contribution of low-energy rations for improving the welfare of feed-restricted birds during rearing. Experimental diets were fed fr

Review of QTL mapping results in chickens

Autor: P.M. Hocking

Publikováno v: World's Poultry Science Journal. 61:215-226

A review of QTL for production, behaviour and disease resistance traits published to the end of 2004 is presented. QTL were located randomly over the genome and there was little commonality between different studies for similar traits. However, there

Effects of low dietary protein and different allocations of food during rearing and restricted feeding after peak rate of lay on egg production, fertility and hatchability in female broiler breeders

Autor: G W Robertson, P.M. Hocking, R Bernard

Publikováno v: British Poultry Science. 43:94-103

1. A 3x2x2 factorial experiment was conducted with boiler breeder females to determine the effects of body weight gain (three levels) and conventional or lower crude protein concentrations in the rations during rearing, and restricted or ad libitum f

Welfare assessment of broiler breeders that are food restricted after peak rate of lay

Autor: G.W. Robertson, Malcolm Mitchell, M H Maxwell, P.M. Hocking

Publikováno v: British Poultry Science. 43:5-15

1. Broiler breeder females were reared on one of three growth curves (ad libitum, conventional or modified restriction) and given rations containing a high or low concentration of crude protein. After the peak rate of lay they were fed ad libitum or

Ovarian follicular dynamics in selected and control (relaxed selection) male- and female-lines of broiler breeders fed ad libitum or on restricted allocations of food

Autor: Graeme Robertson, P.M. Hocking

Publikováno v: British Poultry Science. 41:229-234

1. The reproductive structures of 4 broiler breeder lines fed ad libitum or restricted were compared at 1st egg. The lines were contemporary male- and female-lines and their respective progenitor lines maintained without selection for 20 years. 2. Th

Background Broiler breeders fed ad libitum are characterised by multiple ovulation, which leads to poor shell quality and egg production. Multiple ovulation is controlled by food restriction in commercial flocks. However, the level of food restrictio

Is there a future for alternative production systems?

Autor: V. Sandilands, P.M. Hocking

The trend towards alternative systems of production for poultry meat and eggs in the developed economies is paralleled by moves to increase intensification in the developing world. Alongside these changes is the clearly identified imperative to feed

Beak and oral lesions in broiler breeding fowl

Autor: C.J. Randall, S.R.I. Duff, P.M. Hocking

Publikováno v: Avian Pathology. 19:451-466

Summary Beak, tongue and other oral lesions were observed in broiler breeding fowl reared under a regime of separate sex feeding. Seventy four per cent of the male birds examined at necropsy, at 60 weeks of age, had beak lesions. Severe beak lesions,

Sexual behaviour and fertility in broiler breeder domestic fowl

Autor: I.J.H. Duncan, P.M. Hocking, E. Seawright

Publikováno v: Applied Animal Behaviour Science. 26:201-213

An experiment was designed to investigate the reasons for the decrease in fertility which commonly occurs in broiler breeder domestic fowl in the later part of the laying year. Male broiler breeders were penned individually with 15 females and fed se
