Increase economic benefits by managing layer nutrition
In the breeding process of laying hens, many farmers consider the feed price as the most important, ignoring the economic benefits of breeding. In this regard, the author will start from the nutritional management of laying hens, put forward some measures to enhance economic efficiency for reference.
Five links for effective prevention and control of disease
Disinfection: Thoroughly and thoroughly disinfect the culture equipment, pens, channels, and feces every week.
Management: The most suitable temperature for laying hens is 13°C-20°C, and the humidity is controlled at about 55%.
Vaccine Immunity: In accordance with this field to develop their own immune program. For example, Newcastle disease recommends immunization procedures: first immunisation, 1-day-age-3 day old, II-line, IV-line or clone vaccine. Two exemptions, one week to two weeks after the first immunization, IV line or clone. Three exemptions, 2 weeks to 3 weeks after the second exemption, live seedlings + inactivated seedlings. Four exemptions, 8 weeks to 10 weeks of age, IV lines or clones were aerosolized or spotted. Five free, 16 weeks old - 18 weeks old, live + inactivated vaccine. During the laying period, a live vaccine was immunized from February to March.
Reducing stress: For example, high vitamin supplements, Barton's egg yolk supplements with immunopotentiators, and fast-replenishing electrolytic cubes.
High-nutrient feed: For example, high amino acid, high-protein egg feed material will increase the feed utilization rate of the chicken when it is used for full-price feeds, and it will not cause gout due to high protein, or due to low protein content. Egg fatigue syndrome. Feeding a single feed, for example, is often characterized by high feed consumption, low yield, low egg weight, and low feed returns, making it difficult to increase egg production and benefits.
Pay attention to nutrition management
According to different growth stages, production stages, seasonal changes, health levels, feeding environment, raw material quality, feed intake and other conditions to provide different nutrition to meet the production and living needs of chickens. Only sufficient nutrients for the chicks can ensure their growth and development. It is best to use dedicated egg chick fortification materials 2 weeks before brooding, and then replace them with chicks so that the skeleton can be fully developed. Chickens grow rapidly during the bred period. When the material level is reasonable, the height of the feed line should be adjusted in time. It is best to allow the birds to pick their feet to feed. This can promote the growth of the sacrum as soon as possible. This is more important for roosters, which can reduce the back of the bow and raise the keel, which will help catch up with the hen in the future, that is, increase the fertility rate. Among them, the signs of high-yielding and stable production of chickens: the level of antibodies is uniform and effective; the uniformity and qualification rate are excellent; and the body types are up to standard. Body composition: body type = body weight + skeleton. Features: The chicken's skeleton grows rapidly in the first 10 weeks. The skeleton of the 8-week-old chick can be completed 75%, more than 90% at the age of 12 weeks; the development of the body weight reaches 75% of the whole period at the age of 20 weeks.
Early brooding (first week): Rapid initiation of maternal antibodies.
The results of the study indicate that the type of diet fed to chicks just after hatching or the hatching of eggs or the injection of nutrients to the embryos can affect the development and maturation of intestinal villi and improve the overall growth performance of the poultry.
Control the deadweight rate
Mortality rate refers to the death rate of laying hens after production. Taking Hailan brown chickens as an example, the allowable dead-fishing rate is 5%-6%. However, in actual production, the scouring rate often exceeds 10% or even more. Calculated based on 4% of the difference between 6% and 10%, the difference between the deaths of 10,000 chickens was: 4% 10000 only 20 yuan/only = 8,000 yuan. In addition, these chickens that should not die can only earn 30 yuan each, so the actual loss is 8,000 yuan + 4% 10,000 yuan 30 yuan / only = 20,000 yuan, the average chicken earns less 2000010000 = 2 yuan. From this we can see that there is a great deal of control over the deadweight rate.
The death rate of laying hens directly affects the economic interests of farmers. Death rate is affected by many factors and symptomatic treatment is needed to increase the interest of farmers.
However, the stress at this time is mainly derived from nutrition, namely feed. The multivitamins were added before the chicks were basketed to reduce the adverse effects of transmigration stress.
The basic starting point for controlling the rate of death and maintaining the peak period is to feed, and scientific ingredients are needed to properly match the feed according to the needs of the chicken body. Before laying hens, laying hens need to increase the amino acid and protein levels in feed to meet the needs of mature and sexual maturation. First of all, a comprehensive and balanced supply of nutrition can enhance the body's resistance and immunity. Second, long-term malnutrition can lead to a decline in the function of the immune system, leading to the invasion of external pathogens or the derivation of chronic diseases. Again, adding multi-dimensional, Vitamins to the feed can enhance the body's metabolism and anti-stress ability.
