First of all, according to the results of the previous column and the weight of the selected population, a set of appropriate feed restriction programs should be formulated with reference to the changes in the season. Generally, 4 or 3 restricted feeds should be used in 7-13 weeks; the 52nd limit should be adopted in 14-18 weeks. Feeding; Restricted feeding on June 1 to 19-22, and finally daily feeding. Experience has shown that the best way to use the daily feeding method for chickens is to benefit from the education after the light is added, especially for the chickens raised during the winter. This will have less stress on the chickens and facilitate the production performance of the chickens. Play, but if this method is adopted, the feeding plan should be adjusted appropriately.
Secondly, control the feeding method: First, determine the density and material level of each bar based on the number of chickens to be housed; we all hope to create a better feeding condition for the chicken bar, and always think that the better the material level, the better. However, the actual result is that the more the chicken bar is, the worse the uniformity is. Therefore, when we arrange the material level, we usually set the chicken bar as 12 and the chicken bar as 13. If the material level is still rich, we would rather close it. . The second is to ensure that the chickens have an equal access to food and a relatively stable feeding environment: this requires a black light feed and a fast teaching of the speed of the transfer, and the best way to use automatic transfer; for large Dutch materials The line is considered to add the auxiliary material box, and make the auxiliary material box equal parts of the material line; the general requirement is that the material can be connected in 150 seconds is more ideal, while ensuring that the main material box and the auxiliary material box out of the same, and according to the feed Change the amount and feeding method to properly adjust the size of the outlet and transfer time. In addition, to ensure the normal operation of feeding equipment, it is necessary to do daily inspections and maintenance work, especially when cleaning chicken coops must pay attention to the love of all kinds of equipment, maintenance and repair work, the third is to ensure the accuracy of the preparation and Uniformity prevents possible subjective errors.
Since the main basis for feed during the breeding period is the weight of the flock, we must do a good job of daily weighing. The first is weighing on the day of limited feeding, the weighing time and the weighing place must be relatively fixed, and lay the foundation for the good habit of weighing in the next laying season; second, the weighing ratio of chickens should be at least 10%; The third is to ensure that the weighing apparatus is accurate. This requires that the weighing apparatus must be calibrated before weighing, and that the reading and weighing quantity are accurate. If possible, it is required to have the technicians present in the field, correct the existing problems promptly, ensure the reliability of the weighing, and calculate the weighing results in time.
According to the weighing result, the upper and lower limits of the weight of the adjusted chicken and the number of chickens to be adjusted are determined. The average degree of uniformity is calculated as plus or minus 10% of the average weight of the flock, and then the number of fowls required for each bar is determined based on the ratio of fowls in the subrange. For those birds that weigh more than the minimum body weight ( Generally the above) can be considered to be eliminated; the chicken work should be started from the 9th week, and at the same time it must be ensured that the number of chickens is adjusted to the established plan: if the number of chickens in the process of adjusting chickens does not reach the number of chickens that should be adjusted, the chickens If the group uniformity is poor, you may consider reducing the weight of the big chicken in the chicken bar or the weight of the chicken in the big chicken bar, and keep the bar in the same column after the chicken is finished; the chicken work must be guaranteed on a weekly basis. Weighing days are completed and a full-scale tune-up is made between 13-15 weeks. For the rooster should also adjust the chicken.
