1 Factors affecting chick quality
1.1 Egg Quality
Mainly includes the breeder chicken health condition, the feed nutrient, the feeding management, the biological security and other factors.
1.2 Incubation conditions
Mainly include temperature, humidity, ventilation, turning eggs, hygiene, disinfection and other factors.
2 Improve chicken quality measures
2.1 do a good job of investigation and research
Most breeder farms are absolutely confidential about the quality of their own chicks, and it is generally difficult to understand the facts. Therefore, as a next-level breeder farm must conduct a thorough investigation and research before introduction, it is necessary to understand the survival rate and evenness of the seedlings provided by the peers that introduced the seedlings so as to determine whether the breeder breeder has No vertical infectious diseases such as Salmonella, Escherichia coli, and encephalomyelitis were identified. Based on the above comprehensive results, the introduced farms were determined so that the quality control of chicks could be moved forward. At the same time, it is forbidden to determine the introduction of farms based on the level of prices, and to effectively introduce good quality and quality, and lay a solid foundation for stabilizing and improving the quality of chicks.
2.2 Do a good job of monitoring the disease
While the breeder farms are doing a good job of monitoring antibody against major chicken diseases such as bird flu and Newcastle disease, they will focus on the purification of vertical infectious diseases such as salmonellosis, hemangiomas, and colibacillosis to ensure the quality of eggs and seedlings. . The purification of salmonellosis should be carried out for the first time at the age of 80 days. Plate agglutination test should be used in production if the positive rate is within 1%. If the whole group is inspected, the elimination of positive chickens will not need to be monitored after completion. The qualified eggs produced after the breeding of chickens can be used directly; if the positive rate is between 1% and 3%, the chickens should be tested again at 120 days of age1. Secondly, the breeder chicken can be used normally; if the positive rate is between 3% and 5%, it should be purified once per month, and purified at least 3 times until the positive rate falls below 0.5%; More than 5% of the flock will lose their breeding value. Parents are advised to eliminate or use chickens for commercial flock. E. coli disease purification mainly through improving the quality of health and drug susceptibility test results, regular use of high-sensitivity drugs to control the occurrence of the disease, to ensure that chickens without E. coli infection, to ensure the quality of eggs and seedlings.
2.3 Supply balanced nutrition and put good feed off
Feeding breeders not only provides adequate and balanced nutrition, but also requires attention to feed quality. In production practice, breeder feeds should be prepared according to the nutrient requirements provided by this breed's feeding and management guidelines. High-quality raw materials should be used to formulate diets, and attention should be paid to the effective supply of nutrients such as manganese, vitamin A, vitamin E, vitamin B, choline, etc. The young male rooster should be fed with specially prepared roosters alone. The supply of manganese in feed should be increased by about 20% compared with young hens of the same age, so as to prevent the young male roosters from developing leg problems and growth retardation due to lack of fierceness. This affects semen quality and chick quality. When preparing the breeder's diet, special attention should be paid to the quality and composition of the raw materials, the use of moldy and deteriorating feed should be prohibited, and the amount of miscellaneous pots such as cotton aphid and vegetable pot should be strictly controlled. That is, the amount of cottonseed meal and vegetable pot should be controlled within 3%. Use animal feeds with caution. Fish meal should use imported steam fish meal or high quality domestic steam fish meal that are not contaminated with Salmonella and E. coli. Meat, bone meal, meat meal, bone meal, and feather meal should generally not be used. Oil, choline chloride should be used safe qualified products, otherwise it will affect the quality of chicks. It is important to monitor the content of heavy metals such as cadmium, lead, and chromium in feeds and prevent them from affecting the hatching effect and the quality of chicks.
