Within genotypes, better chick quality induces better liveability and faster growth in broiler production. At this time, the bird must receive the right feed increments in order to successfully complete the growth phase. While layer houses require more complex egg collection systems, broiler breeder egg handling is done more simply. There are many variables that contribute to broiler breeder flock performance. Optimum control of body weight going into peak production means more flexibility and sufficient ‘in reserve’ to provide increased body weight towards the end of the production period.• Broiler breeder farms are advised to avoid bringing their flocks into production too early (23weeks or earlier) and to be extra careful about timing if the females are not properly prepared to start production. Dietary treatments This means precise body weight control during rearing has become even more important and is therefore subject to even more focus. broiler breeder production Oct 12, 2020 Posted By EL James Public Library TEXT ID c26599e4 Online PDF Ebook Epub Library broiler breeders is a challenging task feeding housing equipment lighting climate all components need to be optimally attuned to each other for successful hatching egg "Trace minerals are essential nutrients required in small daily amounts. The same may be true for male broiler breeders to sustain subsequent reproductive performance (de Reviers and Seigneurin, 1990). Copyright © 2020 Alain Charles Publishing Ltd.

Successful broiler breeder management Managing broiler breeders is a challenging task. Trace mineral supplementation is one way to help improve broiler breeder weight gain, feed conversion egg shell and chick quality, hatchability, overall immunity and other productivity measures. Typically recommended BW targets for broiler breeders (2.1 to 2.2 kg) appear to be optimal for egg production. flesh/ fat score of 3-4. With body weight on target at 15 weeks of age the curve can be safely followed. The first 10-12 weeks of the rearing period defines the birds’ frame uniformity while the following 12 to 20 weeks defines fleshing uniformity. After lighting the very small ovarian follicles start to increase in size and produce large amounts of estrogen hormone that influence the production of egg yolk precursors in the liver. Broiler breeder farms have automated egg gathering systems where the eggs gently roll from the nest box onto a conveyor belt to an egg gathering station. “These houses are the future of broiler breeder egg production in South Africa,” says their designer, Brett van den Broeck of Dorna Distributors in Westville. Besides the breeds normally favoured, Cornish Game, Plymouth Rock, New Hampshire, Langshans , Jersey Black Giant and Brahmas were included. Broiler hatching eggs are collected several times a day and only high quality ones are sent to the hatchery to be hatched into broiler chicks. • 17 - 20 weeks – a dual function period - preparation for lay and growth acceleration. Production persistency is maintained by taking the following management guidelines into consideration. Photo-stimulation timing plays a crucial role in flock development and future egg production. Breeding companies have been producing increasingly fast growing and more highly efficient broilers for a number of years and like the broiler birds their parents (the broiler breeders) have registered rapid change. Cobb says that production companies using a maximum of 14 hours of total light are rewarded with a general improvement in the livability of females as well as improved production persistency.• By avoiding over-stimulation with feed going into peak production to avoid excess body weight, says Cobb. Flock uniformity is a key ingredient in the recipe for highly productive flocks, says Cobb because uniform flocks can respond to changing feed allocations as a ‘unit’. The answer to this age-old question is more complicated than you might think! Flocks showing good egg production persistency are invariably those having a light program which does not over-stimulate the birds into production and one that gives a good balance between production and rest (Table 1). But where does the hatchery get the eggs needed to hatch a chick? Excess feeding and energy intake of breeders negatively affected egg production… If an egg is not fertilized, then, of course, it … Companies which develop and supply broiler breeders have to marry two requirements– selecting for maximum egg number produced by the parent as well as selecting for the all-important traits of the broiler bird which is still the main focus. Male and female chicks are usually reared separately until about 4-5 weeks of age. 2.2. Figure 5: Egg production for broiler breeders transferred from 6 hours ( ), 8 hours ( ) or 10 hours ( ) to 16 hours at 20 weeks or maintained on 16 hours throughout ( ). Hens need the energy from feed conversion to maintain their body weight, growth and egg production but too many nutrients allows the production of more body fat, more follicle development and excess muscle. Pullets should be reared in dark out-houses where the light regime can be manipulated and controlled. Birds were weighed and individually placed in galvanized steel cages (0.33 m wide × 0.46 m deep × 0.40 m height) in a broiler breeder house. egg size –However, the feed must still have the correct nutrient concentration or egg production may suffer •Using multiple breeder diets to reduce protein (aa’s) later in lay can be helpful •Important nutrients for control of late egg size may be; linoleic acid, protein and some specific amino acids (Methionine?) If egg production numbers or mating activity is low, it is likely that the number of chicks per hen housed will be less than desirable. A key measure of performance is the Feed conversion ratio (FCR), the ability to convert feed into edible product. The data suggest that broiler breeders reared on 8-h daylengths do not need more than a 14-h photoperiod in the laying period to optimize sexual development or egg production. Total feed reduction from peak egg production should be between 8-14 per cent depending on the time of the year, production persistency and body weight of the females. There is need to study in details the effects of different energy to protein ratio on egg size, production rate, hatchability and broiler efficiency particular between ages, 40-50 weeks, 50-60 weeks and 60-70 weeks. Broiler breeder farms have automated egg gathering systems where the eggs gently roll from the nest box onto a conveyor belt to an egg gathering station. Sixty Cobb 500 broiler breeder hens, 22 weeks of age, were obtained from a local hatchery. Part of the extra nutrients utilised leads to excess fat which impacts negatively on egg production. For example, a flock at 30 weeks of age with an 84 per cent peak has a PI = 114 (30 + 84). Egg production will rise to a good peak but will invariably fall quickly after the parent birds reach 40 weeks of age. From 1985 to 2005, the broiler industry grew by 158%. The hatchery picks up the hatching eggs from the broiler breeder farm one or more times per week. Extensive data on broiler breeder production were generated. the performance potential in all areas of broiler and broiler breeder production. Birds should be weighed at least weekly after transfer to the production facility. Feed allocation is at its most critical when broiler breeders are coming into production. Between rearing and production the light intensity should increase a minimum of 10 times so there is a direct and determined influence on the hypothalamus and the pituitary gland. But the only good broiler breeder egg is a fertilized egg. Getting the correct amount of feed to the birds at the right time is one of the most important factors in the successful raising of broiler breeders. Broiler breeders must achieve the required weekly gain in body weight with good uniformity for fleshing. The broiler industry is the process by which broiler chickens are reared and prepared for meat consumption. It is useful and informative article for broiler breeders. Providing body weight profiles recommended by breeding companies are followed pullets will achieve the required skeletal development. As a general rule when peak production is achieved feed reduction can be implemented by 2 g per week for 2 weeks in a row and then with 1 g per week till 40 weeks of age. As an example, Donald Shaver (originally a breeder of egg-production breeds) began gathering breeding stock for a broiler program in 1950. • Ensuring there is a good sexual uniformity at 23 weeks of age to guarantee a good peak production and production persistency of over 80 per cent. During the rearing period, the light is reduced from 24 hours in 2-3 weeks to just 8 hours with light intensity raised from 3 lux to a maximum of 10 lux so that birds have a clear night and day pattern. The period from photo-stimulation to peak production is perhaps the most critical ‘window’ in broiler breeder management. the birds that produce eggs for hatching into broiler chicks), • fattening of broiler chicks • marketing and processing of finished broiler birds The broiler producer clearly requires birds that will achieve a high body weight, with good carcass quality, over the shortest possible period of time … The rearing phase can be divided into three distinct periods: • 0 - 6 weeks - the growth and development phase. The main goal of broiler breeder management is producing eggs. • 7 - 16 weeks – the control growth phase which brings birds to the optimum body weight. Welcome to the British Columbia Broiler Hatching Egg Commission. Photo courtesy of the Poultry Industry Council. The objective should be to maintain this PI of 114 for the whole production period of 40 weeks. Later on, the females and males will be moved into the breeding barn. The three main steps and stages in the whole broiler production process are: • rearing and managing broiler breeders (i.e. That’s where broiler breeder farms come in. While it is true that integrators are in the The bird’s liver assumes a paler colour due to increases in fat content to cope with and facilitate production of the egg yolk liquids. 28 (4) 2018 965 hatching performance of arbor acres broiler breeder strain at four production phases with three egg weights and storage Evonik, a specialty chemical group, has announced that it will manage all of its output of MetAMINO (DL-methionine) at three global hubs (America, Europe and Asia) to maximise economies of... Speciality chemicals company Evonik has stated that it sees a clear confirmation of reliability and security of methionine supply to the protein industry in China. As a general rule of thumb, for every 200 g more of body weight after peak egg production the bird needs 5 g more feed for maintenance. Cobb, the international producer of broiler breeders, has set out what they regard as the correct management and nutrition of the parent birds to ensure customers obtain maximum number of eggs from their broiler breeders. These results with Chinese Yellow breeders are consistent with the lack of significant effect of dietary Fe on egg production and egg mass of Cobb 500 broiler breeder hens (Abbasi et al., 2015). BROILER BREEDER • Production cycle 24-64 weeks • 24 weeks of age 5% production • 29 weeks of age peak (85%) - 183 Total Eggs - 175 Hatching Eggs - 150 chicks - 85 % standard hatchability • Pakistan - 164 (Max. Birds came into lay quicker with the higher light regime but showed poorer egg production post peak resulting in up to 10 less eggs. Lighting and feeding throughout the study followed Cobb-Vantress (2010a) recommendations. However, egg production in broiler breeder hens was reducing gradually overtime and thus their nutrient requirements for achieving maximum egg production should be gradually reduced. Also important is the underlying relationship between energy status and the ph… Sexual uniformity also includes fleshing and fat uniformity so females are in the best possible condition to continue good egg production. Body Weight should not increase more than 18% from start to peak production. broiler breeder production Sep 28, 2020 Posted By Irving Wallace Library TEXT ID a2658e49 Online PDF Ebook Epub Library published in 2000 it provides a look at all production segments involved in the production and processing of broilers 1 broiler breeders 2 hatchery a the hatchery is Hens need the energy from feed conversion to maintain their body weight, growth and egg production but too many nutrients allows the production of more body fat, more follicle development and excess muscle. Conventional fast growing broiler breeder lines with access to ad libitum feeding may consume energy up to 30 to 50 % in excess of the actual requirement for maintenance and optimum egg production (Lopez and Leeson, 1994). Over-supply of nutrients results in excess fat and excess follicle production which may lead to problems relating to SDS (Sudden Death Syndrome) and Haemorrhagic Liver Syndrome.
