Efficient feeding and management of new technology layers

Cases, with changes in energy regulation and control of the chicken, that is: overweight, proper adjustment of the compound energy; underweight, appropriate compound to increase its energy. Usually increases the energy of the compound method is used to add oil into the Wai Ching 7.4 line. Regulation of body weight, feeding amount subtraction method can also be used. In the late bred, 18 weeks of age, body weight is more important. The weight of its final 18 weeks of age the amount of egg production, egg weight showed a strong positive correlation. 18 weeks and 5 weeks old echoes,[link widoczny dla zalogowanych], is the crucial period of two chicken life. Late in the breeding objectives of management, groups, uniformity should be maintained above 90%, otherwise, chickens produce irregular opening, after the egg production is not ideal. 2.2 The incubation period of incubation period of sexual maturation and sexual maturity are two factors that feed protein and light. Regulation of sexual development, can be under the same dietary protein to increase the light to accelerate sexual maturation, delayed sexual maturation or reduced light. For controlling mature hens to maintain body reserves the consistency of development and sexual development, from the late brood rearing is best to use a constant light post 8 hours, the maximum can not be higher than the 1od, time. Only in this way late in the breeding, pre-production period to produce a more intense light to stimulate an effective response. Otherwise, the light stimulus ineffective. 2.3 The regulation of chicken breeding populations mature and late sexual maturity before 12 weeks of age as pre-incubation, early rearing chickens not accumulate fat; after the incubation as the late start of chickens bred late accumulation of body fat. Since then, the chicken body will undergo a qualitative change. Therefore, 12 weeks of age is an important constitutional change Yucheng Ji turning point, followed by 12 weeks of age for the physical production of chickens ready for the opening of an important period. Late in the breeding sheds open using only natural light, whether the chicken or the smooth quarter against the quarter of the chicken, the natural light is higher than the 8d, when the cloudy, rainy fill light must turn on the lights, speeding up of development. Sexual development in line with this trend, the nutritional supply of the late bred early material remains unchanged, that feed energy 11.7MJ/kg, protein 15% ~ 16% abolish the traditional post-bred breeding low nutrient feed supply (energy 11.3MJ / kg, protein 12%) of the practice. This high concentration of feed will promote physical development, body weight, body mature, high concentrations of feed and natural light necessary to promote sexual development, sexual maturity. 3.1 3 egg feeding and management of the supply of pre-production material the use of natural light and the incubation continued supply of high concentration of feed post, promote early maturation and sexual maturity of the traditional farming methods. On production days in advance, put forward to re-define the expected date of the new problems. Traditional feeding to three weeks for the birth of 19,20,21. Efficient type of feeding and management in the late incubation body weight to body weight began to open to the egg production rate of 5% of the expected delivery date. Expected date of birth supplied material is 1 / 2 post-incubation with high concentration of feed (protein 15% ~ 16%) +1 / 2, the peak of egg production material (protein 17% ~ 18%) mixture. Pre-production material of high nutrition can undoubtedly produce nutritional requirements to ensure open and conducive to maintaining high yield lasting. Peak feeding chickens laying 3.2 to open the supply capacity of 5%, or replace the egg peak material. The peak concentration of egg material: energy 11.91MJ/kg, crude protein 17% to 18%. At this time,[link widoczny dla zalogowanych], dietary calcium and phosphorus content placed in a prominent position important, in order to meet the needs of peak egg production,[link widoczny dla zalogowanych], feed requirements in the calcium content of 3% to 4%, 0.4% phosphorus 0.45%. However, according to the physiological characteristics of egg, egg shell calcification mainly at night, it is proposed the appropriate dietary calcium content to leave room 3:00 to 4:00 every afternoon and then a one-time massive supply gap of shells, in so doing conducive to the direct absorption of calcium, can improve eggshell quality, and the South in the low calcium content in feed feed palatability. 3.3 Management of light near the egg laying of light 12, 'ix, the illumination of 3 W / m. Egg production rate of 5% from the beginning, to increase the illumination time per week o. 5d, when the egg until it reaches its peak, and finally, according to the time constant 16dx, the illumination of 3 watts / m. Peak and begin to slide the end of laying, when laying rate slipped to 70%, according to the time 16.5d, when the illumination of 3 watts / m: When laying rate slipped to 50%,[link widoczny dla zalogowanych], according to when the 3d, when the illumination 3 W / m; 17,, ix to chicken out when the maintenance light. 3.4 sheds laying period Sherwin temperature 22 ~ 28 ��, the highest rate of egg production. However, practice shows that temperature to keep homes more than 4 ��, did not significantly affect egg production and egg weight. 4 ~ 13 �� low temperature environment, the advantages of homes is not conducive to bacterial growth and droppings, and throw feed fermentation, the environment is not easy to pollution, air quality, a little drawback is that feed consumption increased, and high egg production environment Sherwin ratio, the advantages outweigh the disadvantages, therefore, insufficient equipment conditions in the chicken coop, the environment should be promoted Sherwin laying low.
