Cobb Breeder Control Information: Body weight keep watch over, weighing & research

Editor’s word: This newsletter is an excerpt from the Cobb Breeder Control Information and extra articles will practice. The Information used to be designed to focus on crucial elements which might be perhaps to persuade flock efficiency. The control suggestions mentioned have been advanced particularly for Cobb merchandise. The suggestions are supposed as a reference and complement in your personal flock control abilities in an effort to follow your wisdom and judgement to acquire persistently excellent effects with the Cobb circle of relatives of goods.

There are two really helpful techniques to feed a flock in rearing and make certain that the birds are in situation at 20 weeks of age.

1. Feed in keeping with the Cobb body weight profile this is particular for the breed. Remember {that a} feed alternate takes 2 to a few weeks to be detected in body weight alternate. Due to this fact, widespread will increase and reduces in feed alternate will also be complicated and outcome in fluctuating bodyweights which will induce pressure and have an effect on flock uniformity.
2. Feed in keeping with a pre-determined and confirmed feeding regime with particular feed specs. The birds are fed in line with a program and the birds’ bodyweights are stored between 98 and 102 % of the usual. If the body weight deviates an excessive amount of from the usual the feed quantities must be adjusted up or down in small increments starting from 1 to a few g (0.22 to 0.66 lb/100 birds). Once more, remember that feed alternate takes 2 to a few weeks to be discovered in feed limited birds.

The 2 described feeding strategies is also used in combination. First of all, practice the primary idea by which the feed quantity is desperate by means of the body weight construction in rearing. As soon as a excellent feeding profile is desperate, the second one idea can be utilized making it more uncomplicated on control basically. The usage of each strategies will give extra constant effects and good fortune in assembly manufacturing goals.

The target of body weight keep watch over is to rear the entire birds to the objective weight for age with excellent uniformity. Body weight goals are completed by means of controlling feed allowances. Feed quantities all through rearing are in line with body weight achieve and upkeep, while in lay they’re in line with those two elements together with egg manufacturing and egg weight. Correct feed quantities can most effective be desperate if the body weight is measured as it should be each and every week.

Hand Weighing

The scales used to measure body weight should have a most capability of 5 kg (11.02 lb) and be correct to +/- 20 g (0.05 lb). Scales should be calibrated on a standard foundation. It’s wonderful to make use of digital scales with a printout capacity. This may increasingly scale back human error and help the weighing workforce. At 3 weeks and older, weigh 3 % of the women and 10 % of the men or 50 birds at the least consultant pattern. To extend accuracy of the sampling, use a catching pen, don’t randomly select up and weigh birds. Position catching frames at set places around the barn – entrance, heart and again. Weekly pattern weights should be consultant of the entire space. Don’t position a catch body close to the primary hopper house as a result of birds on this house generally tend to weigh above moderate from consuming feed from the hopper. 

Forcing birds into the pen or selectively catching birds and hanging them in a pen can lead to a non-representative flock pattern for weighing. As a substitute, the catch body must be positioned to permit the birds to freely input the pen for a extra consultant pattern of the flock. Weigh each and every chook personally throughout the catch pen, together with small birds, and don’t reject any weights, excluding for sexing mistakes. After every chook is weighed, unencumber the chook into the home. Proceed weighing till the pen is empty.

File every weight and calculate the typical weight in addition to the flock weight distribution. Plot the typical body weight at the suitable chart and use this knowledge to calculate the feed quantity for the next days. It’s additionally vital to decide if the feeding program is operating and conserving the birds just about the usual body weight.

Automated Weighing

Automated scales are gaining popularity with advanced weighing apparatus and instrument. They may be able to be used day-to-day and over a particular period of time on a daily basis. Normally, measurements are taken for 1 to two hour(s) previous to feeding. For instance: if the lighting fixtures activate at 7 AM, then scales function from 7 to eight AM or 9 AM with feeding beginning at both 8:01 or 9:01 AM.

On moderate, 100 women will step at the scale consistent with hour. The computerized scales are both a suspended or mounted platform, however there is not any transparent benefit for both. The dimensions vary is most often set between +/- 25 to 30 % of the inhabitants imply body weight.

Within the graph above, the day-to-day, computerized weighing information (blue dots) persistently practice the weekly body weight usual. At 16 and 17 weeks of age, hand weighing (inexperienced dots) used to be finished close to the primary feed hopper and the body weight greater in comparison with the mounted place of the automobile scale. The diversities in body weight have been corrected when the hand weighing used to be finished close to the automobile scale. This can be a transparent instance how location adjustments in hand weighing may cause inaccurate moderate bodyweights that lead to adjustments within the feeding program, probably affecting conditioning of the women. That is in particular vital for flocks between 16 and 20 weeks of age when a set construction agenda is needed to get the women in the suitable situation at 20 weeks of age.

Benefits of computerized scales:

• Day-to-day weights to be had and graphically represented. Most present space controllers have instrument for assortment and research of body weight information.
• Many providers be offering stand-alone laptop techniques which will gather information from as much as 8 scales positioned amongst a number of properties.
• Preferrred for properties with out pens.
• Fast reaction to any deviations from the usual – indication of conceivable feeding apparatus or distribution issues.
• Information is extra constant in comparison with hand weighing.
• Much less exertions – a bonus with regards to biosecurity and exertions price.
• If the use of pens, calculate weighted moderate uniformity.

Disadvantages of computerized scales:

• Now not appropriate for weighing men.
• Scale placement in manufacturing is vital to stop weighing a combination of female and male breeders. Scale placement at the slats will give a higher illustration of feminine weights.
• Much less chook dealing with with automatic scale techniques can build up anxiety in a flock.
• Auto scales can be utilized till 30 to 35 weeks of age with excellent accuracy.
• After top manufacturing heavier women generally tend to steer clear of scales.
• Would require body of workers acquainted with information assortment, examining and computing generation.
