The size and weight of a selected chicken cage broiler breeder is greater than that of an egg breeder breeder, and its requirements for cages are also higher. Some farms use broiler cages to raise broiler breeders, and some use cages that do not meet specifications for cost savings. This will limit the genetic potential of broiler breeders and affect their health and production performance.
In general, the length, height, depth and sturdiness of broiler breeder cages are greater than those of egg breeder cages. The production performance is better with a two-step cage cage. Each layer specification is: 2004039(cm), divided into five compartments. Two are trained to facilitate management and observation, and are conducive to artificial insemination. The cage of the rooster needs to be tall, so that it has sufficient freedom of movement. Do not let its head rise above the cage, so as to avoid damage to its crown and meat, affecting the quality of semen.
The two feeding fast, accurate, uniform cage feeding broiler must be done when feeding: fast, accurate and uniform. Only skilled and responsible workers can do this job well. It is very difficult for new workers to change jobs. This requires that before each feeding, the amount of material needed for two chickens in a single layer cage should be calculated. After grading, it is best to leave more material when the chickens are fed, and then feed them according to the situation, so as to ensure that the amount of material in front of each chicken is even and reasonable. Otherwise it will seriously affect the flock uniformity or egg production rate. Therefore, the husbandry managers should fully mobilize the enthusiasm of the workers and cultivate a group of highly responsible and skilled workers to ensure the normal production performance.
Three Reasonable nutrient supply The current nutritional standards recommended in the breeding manual are based on the physiological needs of raising broiler breeders. There is no uniform cage standard. There is less activity in cages and there is a relative reduction in energy requirements. Daily intake is 3 to 5 grams less than standard for raising, and vitamins and minerals need to increase. Therefore, energy can be used when designing formulas with a lower limit standard, crude protein can be used as an upper limit standard, and vitamins and trace elements are each 1.5 times the standard for raising. In the peak diet, calcium was kept at 3.75% and phosphorus was not lower than 0.8%-0.9%. In short, a reasonable supply of nutrients can guarantee healthy, high-yield, and stable production of cage-reared broiler breeders with reduced feed intake.
Formulation of the Four Lights Program The time and intensity of artificial light supplements for broiler breeder chickens can be obtained using the data recommended in the Breeder Breeding Management Manual, but the light sources must be balanced. Two-step ladder cage lighting is easy to solve, generally 2 meters below the ground to irradiate the light, the light bulb should be added light angle response cover to ensure that the upper and lower layers of chicken can receive enough strength. The illumination intensity should be based on the illuminometer test data, and the error of the illumination intensity converted from the wattage should be relatively large, which may cause insufficient illumination or waste.
The cultivation of five kinds of male roosters is the basis for the implementation of artificial insemination techniques. Therefore, it is particularly important to breed a rooster. In addition to strengthening management and carrying out scientific cutting and cutting off during the brooding period, we should pay more attention to pre-production training. Since sexual maturity of cocks is 2-3 weeks later than that of hens, male and female hens must be sexually mature. The body size of pre-production cocks is more than 30% of that of hens. At the same time, it is best to give 16 hours of light stimulation 3 weeks in advance, and massage in the afternoon every day to collect sperm, the action can not be rude during training, and finally select the male and female ratio of 1:30 reflect the strong cock to stay for planting.
Sixthly, careful observation of chickens in cage chickens due to the higher density, is not conducive to the observation of chickens, especially in the brooding period is more obvious, so we must carefully carefully around the cage for careful observation to prevent the emergence of abnormal conditions after the chicken can not be found and deal with. When the chicks are just transferred to the rearing cages, the chickens will have a short-term anxiety due to the new environment. For the chickens that come out of the cages, they must be caught in the cage in time, and it is necessary to check whether the chickens and all the chickens that are wounded are timely. Drink water. In addition, in daily management, we should carefully observe the flocks each time, and be aware of the conditions of the birds such as food intake, drinking water, excrement, and mental status, timely prevent diseases, strengthen management, and reduce economic losses. .
Seven regularly sampled weighing cages Weighing cages can be fixed and weighed, and 5% -10% of chickens are weighed in the afternoon on the weekend of the restricted feeding day. When it is found inappropriate to adjust the body weight, large-scale chickens should be placed in the lower cages, small-scale ones placed in the upper cages, and fed separately to control or accelerate the increase in body weight. When the chickens have dead oysters, the chickens at the far end of the cage should be used to make up the vacant cages in time, which is convenient for feeding and management.
