Broiler Management Basics

Broiler Management Basics
I have drawn up a list of 10 key management points for broiler chicken production. Although it could have 100 points, I believe that this list has universal application and covers the most important issues. The list includes; preparation, temperature, ventilation, air quality, lighting, stocking density, feeding, litter management, sex separate growing and uniformity. All these issues overlap and there is far too much to discuss all of these topics today, so I have chosen 5 principal subjects - preparation, ventilation, air quality, feeding, and uniformity. 0521jap

Cobb Genetic Programme
The Balanced Approach Breeder Broiler Processing I would like to turn now to our breeding programme and the philosophy of our approach to the genetic development of the Cobb 500. Our geneticists take a balanced approach to the development of the Cobb We do not put undue emphasis on any one characteristic, we apply pressure on all characteristics in order to try to maximise the economic return for all those involved in the production of chicken meat. In the case of the breeder; this means maximising the number of viable day old chicks, whilst continuing to improve shell quality, fertility, hatchability and liveability. In the case of the broiler grower; this means maximising liveweight gain, whilst continuing to improve feed conversion efficiency and liveability. In the case of the chicken processor; this means maximising meat yield, whilst continuing to improve conformation and meat quality. The selection criteria that we have adopted have been developed from a clear understanding of the way in which the market for chicken meat products has developed over the years. 0521jap

Average Annual Improvement
Cobb 500 Average Annual Improvement One extra chick/breeder 50 grams in broiler liveweight 0.02 in feed efficiency 0.3 per cent in breast meat yield 0.1 per cent improvement in liveability The genetic development of the Cobb 500 cannot, however, stand still. Our competitors have seen our success and will wish to emulate our product. The annual gain in genetic potential that we claim the Cobb 500 can achieve is 1 extra chick per breeder, 50g more broiler liveweight for age, 0.02 points improvement in broiler feed conversion , 0.3% more broiler breast meat yield, and 0.1% better broiler liveability. In addition, our balanced breeding programme has led to the development of a broiler chicken that can adapt to conditions anywhere in the World. In the UK alone, Cobb 500 broilers are grown in conventional houses to ages as young as 25 days and on free range to ages as advanced as days without any difficulty. Anywhere you go in the World you will find the same Cobb 500. The following slides show some of the results obtained by customers in the UK. 0521jap

Preparation Maintain biosecurity Clean the house properly
Kill all the vermin Proper disinfection Set up all the equipment Find out when the chicks will arrive Good preparation involves attention to the detail of all these aspects of management during the cleanout between flocks. It is important to: maintain biosecurity throughout the turn-round; clean the house properly; kill all the vermin; disinfect the structure and equipment properly; set up the equipment before the chicks arrive; find out when the chicks will arrive in good time. The most important of these points, in my opinion, are proper cleaning and disninfection; and to find out when the next flock of chickens will arrive - so that all the other tasks can be scheduled and completed properly. 0521jap

The story behind this picture illustrates many of the problems that can be the result of poor preparation. The house has not been properly cleaned, and was not disinfected at all. The equipment was not properly cleaned and was still not working properly when the picture was taken. The house was not warmed properly before the chicks arrived. As you can see, the birds are huddling under the brooders. No provision for ventilation has been made. All these problems arose because the birds arrived ‘unexpectedly’. The second picture, taken during my previous visit to Japan, shows excellent preparation prior to the arrival of the chicks. Preparation 0521jap

A large proportion of the problems that I see in chicken houses are the result of inappropriate ventilation. It is not my intention to discuss ventilation systems in detail, but I do want to make some comments regarding ventilation rate. The minimum ventilation rate must provide enough fresh air to ensure that the birds have sufficient oxygen for efficient respiration and that carbon dioxide, dust and noxious gasses are kept at tolerable levels. The minimum ventilation rate should be related to the birds’ metabolic rate, in terms of either their liveweight or feed consumption. The calculations that I use are given in this slide. These ventilation rates have been recently updated. These requirements need to be regularly reviewed and updated if necessary, to take account of the increasing genetic potential of the chickens. The maximum ventilation rate is required to control heat stress in hot conditions. There are many ways of calculating the maximum ventilation rate, but the method that I favour is based on the heat output of the birds and an assessment of the risk of heat stress. In UK conditions the climate is cool and temperate, so a moderate temperature lift is acceptable. In Japan a more stringent specification may be needed. The specification for tunnel ventilation requires a minimum airspeed of 2m/s at bird level for broiler chickens. 0521jap

û ü Doing the Right Things... Ventilation Design and Management
This house will not allow the chickens to exhibit their commercial potential for agricultural performance. Controlling both the ventilation rate - especially at the minimum level - and the air distribution will be difficult. Houses like this can still be used to grow chickens, but their owners must recognise the limitation that they place on broiler performance. New houses should all look like this one. This house is controlled environment, featuring minimum ventilation control, tunnel ventilation and pad cooling. The temperature outside was 40degC, the temperature inside was 25degC.

Doing the Right Things... Minimum ventilation for air quality
The minimum ventilation system must be properly designed, so that it is capable of delivering the appropriate amount of air. This is one of the new pullet rearing houses, recently constructed by CVI in Arkansas. Proper use of the minimum ventilation system during the first few days after the chicks have been placed will help to ensure that the flock does not suffer ascites or other metabolic diseases. The minimum ventilation system must be switched on and working the day before the chicks arrive. Ventilation Design and Management 0521jap

Minimum Ventilation Rate (m3/s) for 10,000 Cobb 500 Broilers.
These are the minimum ventilation requirements of a flock of 10,000 Cobb 500 broiler chickens, based on their metabolic liveweight. In fan equivalents, 10,000 as-hatched birds will require one 610mm fan running at full speed for 20% of the time from day-old to day 7. From day 21 to day 28, however, that fan should run continuously, and; by the time the birds are 42 days of age they will require 1.5 fans running to satisfy their minimum ventilation requirements. 0521jap

Doing the Right Things... Maximum ventilation - to control heat load, e.g. tunnel system Proper design and management of the ventilation system to provide control over the heat load within the building and to limit the effects of heat stress in hot weather are worthwhile investments. The development of ventilation systems that allow the use of efficient, high volume fans, e.g., tunnel ventilation, make such investments very cost effective. This picture was taken on the same site as the previous one illustrating the minimum ventilation system. The fans are high volume units, supplied by Multi-fan. As in the case of minimum ventilation systems it is important to recognise the effect of genetic improvement on the ventilation requirements of the birds. Chickens that grow quickly produce more metabolic heat than those that grow slowly, and ventilation specifications need to take into account the developing requirements of the birds of tomorrow.

Air quality Oxygen >19.4% Carbon dioxide <0.3%
Carbon monoxide <10ppm Ammonia <10ppm Inspirable dust <3.4mg/m3 Minimum ventilation must be increased if these parameters are not met. The maintenance of good air quality is the purpose of the minimum ventilation system. This table shows the parameters that I use to describe good air quality. These are the tolerance limits of broiler chickens for; oxygen, carbon dioxide, carbon monoxide, ammonia, and inspirable dust. Exceeding these limits increases the risk, in particular, of damage to the birds’ respiratory system that may lead to ascites or other cardio-vascular disease. If these limits are exceeded the minimum ventilation rate must be increased. 0521jap

Feeding - delivery Raw materials Water Feeding space Feed form Timing
Controlled feeding The way in which feed is delivered to the birds is as important as its nutrient specification. Good quality feed can only be made from good quality raw materials. Water is essential to the health and productivity of broiler chickens. Neither feeding space nor feed form - mash, crumble or pellets - should limit the birds’ nutrient intake or the digestibility of the feed. Feeding during the night is a useful strategy to help in the control of heat stress. Controlled feeding is becoming a more common practice in situations where it is important to hit a specific target weight. I want to take water as an example of some of the principles outlined above. 0521jap
