1 Specific measures
1.1 First, add appropriate amounts of antibiotics and 1.5 times the amount of multivitamins in the feed within 3 days before and after the transfer to enhance the anti-stress and disease resistance of the birds.
1.2 Adjust the flock as quickly as possible in accordance with the size of the flock, and focus on the individually slow-growing, low-weight chickens.
1.3 Reduce the level of calcium in this part of the chicken feed, and add 1% to 1.5% of vegetable oil in the feed as a part of carbohydrates to supplement metabolic energy in the feed. It is well known that the net energy value of vegetable oil is high, and the heat increase is less, which can significantly improve The utilization of feed makes the chicken gain weight quickly.
1.4 It is also necessary to flexibly adjust feed nutrient and lighting procedures according to the weight gain status of large groups and small flock chickens.
If the weight gain is rapid, the light time should be increased accordingly, and adding a suitable amount of VE to promote sexual maturation; otherwise slow or unchanged, in order to limit the age of the chickens to open, in order to obtain the best synchronization of the chickens or Close to the goal of synchronous production, improve the overall rate of egg production.
2 Results The implementation results showed that 3 to 4 weeks after the low-weight chickens adopted the separate feeding measures, the weight recovered significantly, almost close to large groups. When the egg production rate reached 50%, the production time was about 16 days later than the large group, the egg weight and the same period. The difference in egg production rate is not significant. The peak maintenance time was gradually adjusted because of the chicken position. The data was not accurate, so no comparison was made.
3 Summary and discussion
3.1 The addition of vegetable oil to feedstuffs makes it obvious to restore weight gain to some of the groups whose body weight is not up to the mark, and the difference in opening time is not significant. Since it is not easy to raise the broiler house on the Internet in separate groups, it is recommended to go up one week in advance (17 weeks of age) and pick out the poorly bred groups in the caged egg house to feed them as soon as possible so that they can restore weight and shorten their size. The number of days between production starts to increase the group's egg production rate and total egg production.
3.2 The amount and time of adding vegetable oil mainly depends on the weight of the chicken. If the chicken is too small, the amount of oil should be increased to between 1.5% and 2%. If you can advance to the rearing house, add the best.
Pre-production adjustment management technology for caged egg-laying hens
At present, chicken farms generally adopt a conventional 18-week-old transfer group. The quality uniformity of the chickens in this period is a precondition for whether the chickens can fully realize their productive potential and obtain high yields. However, in practice, especially for large-scale breeding farms, the stocking density generally slightly exceeds the upper limit of domestic flat-net stocking density (8 to 10/m2) by 1 to 2, which inevitably leads to a lower limit of the standard uniformity. In the following groups, these chickens generally account for about 10% to 20%. There are two categories: one is sick, the remaining chickens should be eliminated, and the other is healthy chickens that are disease-free. However, due to inadequate feeding intake due to competition for food in the flock, the weight is not enough. If this part of the chicken is eliminated, it will result in loss and waste (hereinafter referred to as chickens in this part). Because of the presence of chickens, the uniformity of chickens and the passing rate of commodities are reduced. This has limited the economic efficiency of chicken farms to a certain extent, and it is necessary to take measures to improve the uniformity of chickens in order to reduce the number of chickens. It is of great significance to the chicken farm. Therefore, for those groups that have not reached the standard of weight, adjustment techniques such as management and feed nutrition should be adopted so that the chickens can gain full weight three to four weeks before the due date, so that the weight can basically reach the target level. Or close to large groups, so that it gradually opened. Although this part of the chicken has a relatively late production, the relative survival rate of the whole laying period is relatively low, the ratio of eggs is higher, and the number of laying eggs is slightly lower. However, as a whole, in terms of chicken population, the overall yield and laying rate of the chicken house can still be increased. And get better economic benefits.
