High yield five points
Due to climatic reasons, laying hens have different degrees of decline in egg production in winter, but the price of eggs in the same period is relatively high. Therefore, increasing winter egg production in chickens plays an important role in raising chicken economic efficiency.
Reasonably arrange the peak period of egg production: the peak laying season of laying hens is about 28-35 weeks old, and the laying rate is generally more than 85%. The physiological function of laying eggs is the most vigorous and should be used effectively. When the egg laying peak season is arranged in winter, the early spring brooding should be changed to the 5th to 6th months of brooding, when the temperature gradually rises, the survival rate of brooding is high, and the peak period of egg production is just in winter.
Maintain a suitable environment in the house: Only by creating a suitable environment for the chicken can it be possible to have a high egg production rate in winter. The first is temperature. The most suitable ambient temperature for laying hens is 13°C to 21°C. When the broiler's temperature is lower than 8°C, the laying rate and feed conversion rate are significantly reduced. Holding the temperature of the house approach: walls, doors, ceiling to be tight, may be discounted in the firewall to build green or warming fire, the temperature in the house is maintained at above 13 ℃; second humidity. The relative humidity in the house should not exceed 60%, so chicken manure should be regularly cleaned and some ash should be added to absorb moisture; the third is ventilation. Pay attention to ventilation and keep the air in the house clean. At noon on a sunny day, the south window can be opened for 10 minutes to discharge dirty air.
Adjusted feed formulation: Suitable formula for winter use, egg production rate is about 80%: corn 64.0%, bran 3.0%, soybean cake 17.2%, loquat leaf powder 2.0%, fish meal 2.5%, blood meal 4.8%, bone meal 2.0% Shell powder 4.5%. The formula has a crude protein content of 16.8%, metabolizable energy of 11.49 MJ/kg, calcium of 3.2%, and phosphorus of 0.6%. Feed 3 to 4 times a day, feed dry powder, drink clean water at the same temperature as Shev, and pay attention to feeding grit.
Reasonable drinking water: If you do not drink water for 36 hours, it will affect the chicken's egg production. Therefore, it is necessary to ensure that the laying hens drink water. In winter, the chicken should be given clean and warm drinking water to prevent the chicken's stomach from getting cold and get sick. At the same time, it is also good for keeping chickens hot.
Satisfy lighting requirements: The lighting time during the breeding period needs to be maintained at about 8 hours per day. For broiler chickens that are arranged at the peak of the laying season in the winter, artificial lighting should be added later. The laying hens entered 21 weeks of age and were exposed to light for 1 hour each week. The daily light time at 26 weeks was 14 hours. Practice has proved that laying hens can meet the needs of the peak period of egg production every day with 14 hours of light. When replenishing, it is necessary to switch lights on time. Otherwise, it will disturb the response of laying hens to light stimulation. The lamp installation height is 1.8~2.0 meters from the ground, 40 watt bulbs, the lamp spacing is about 3 meters (if it is 1.5 meters, a 25 watt bulb should be replaced), and a 40 watt bulb per 18 to 20 square meters can be installed. .
Clever use of additives
Adding appropriate additives to the hen's diet can make the layer more productive. Which additives can make laying hens produce more eggs?
Choline: Add 0.5% choline to the layer chicken feed. The egg production rate can be increased by about 3%, and the average egg weight can be increased by more than 2 grams.
Red chili powder: Adding 1% of chili powder to the layer chicken feed and adding the same amount of loquat powder and a small amount of vegetable oil can increase the egg production rate by about 8%.
Honey: Add 1 gram of honey to each chicken every day. The method is to dilute it with water, and then mix it into the feed twice a day early and late to increase the egg production rate by 8% to 12%.
Sunflower dish powder: Adding 3% to 5% sunflower dish meal in the layer chicken feed can increase the egg production rate by about 15%.
Vitamin C: Adding 50 grams of Vitamin C per ton of layer chicken diet can increase egg production by 11.7% and reduce feed consumption by 15%.
Vitamin E: Add 10 mg vitamin E to each laying hen per day for 3 consecutive days. After 5 days, the egg production rate can be increased by about 8%.
Goat milk: Starting from the chicks, adding the goat milk to the feed can make the laying period one month ahead of schedule.
Feather powder: Add 3% to 5% feather meal in layer chicken feed to increase egg production rate by about 15%.
Gypsum powder: Feeding hens per day to 0.5 to 3 grams gypsum powder, laying hens can be improved rate of about 9%, egg weight increase; moult accelerate molt the chicken, egg early recovery.
Zinc sulfate: Add to molt egg feed 2% of zinc sulfate, 7 days of continuous feeding, egg production rate of 5% can be picked up, fed continuously for two weeks, the egg production rate may be increased by 10%.
Bentonite Bentonite end commonly known as white clay, bentonite rock. End of the 5% bentonite layer diets, mixed evenly, and then mixed with water wet feeding, egg production can increase more than one percent.
Fly larvae: Add 10% fly larvae to the broiler's feed. Early and late feeding can increase egg production by 20%.
Earthworms: earthworms washed, blanched in boiling water for 3 to 5 minutes, remove and chopped, 10% in layer diets, egg production increased by 10% to 15%.
Waste paper scraps: The waste books and old newspapers are cut into pieces and mixed in layer feed according to 10%. After one month, the egg production rate can be increased by about 12%.
Pine needle powder: Adding 5% pine needle powder to the layer chicken feed can increase the egg production rate by 8% to 12%.
Kelp powder: Adding 2% to 5% of the kelp powder processed from kelp in the layer chicken feed can increase the egg production rate from 6.62% to 14.38%, and can also increase the iodine content of the egg yolk by more than 7.28%.
Baking soda; ie sodium bicarbonate. Adding 0.5% baking soda to layer chicken feed can increase the egg production rate by 3.3%, and it can also reduce egg breakage.
Rare Earth: In the basal diet of laying hens, adding 30 ppm of rare earth can increase the egg production rate by 5%, and the egg weight can also increase by 4.5%.
Peanut shell powder: Adding 3% to 5% peanut shell meal in the layer chicken feed can increase the egg production rate by about 10%.
Pumpkin: When laying hens are moulted, 30 grams of ground crushed squash are added each day to shorten the moulting period of 5 days, and the egg production can also be increased.
1. Concentrate formula: 45% corn, 19% cooked bean cake, 18% high protein corn, 10% bran, 5% fish meal (or yeast feed), 1.7% bone meal, 0.4% calcium carbonate, 0.8% salt , trace elements and vitamin E additives 0.1%.
2. Diet composition: 0-30 days of postpartum milking cows, 6.5 kg of fine concentrate per day, 8 kg of brewers' grains, 15 kg of silage corn, and 4.5 kg of hay (Lycopersicon esculentum). The ratio of concentrate to roughage (calculated on dry matter) is approximately 55:45 or 40:60.
When there is too much concentrate in the lactating cattle diet and its crude fiber only accounts for 13%-14%, in order to maintain the rumen's normal environment and digestive function, to prevent the pre-gastric relaxation and milk fat content decrease, additional magnesium oxide and bicarbonate should be added. Sodium buffer. The amount of sodium bicarbonate used is 1%-1.5% of concentrate, and magnesium oxide is 0.5%-0.8% of concentrate. The application results show that the milk fat percentage can be increased by 0.4%-0.5%.
3, feeding methods: 1 traditional feeding methods. After calving, cows are allowed to freely eat quality hay and try to avoid feeding too much silage corn. Observe the feeding situation after feeding. If there is no leftover material and a lot of hay is eaten, the spirit, defecation, and rumination are all normal, and the amount of milk increases, 0.5-1 kg of fine material can be fed daily; if any Less material, slow eating, poor appetite, leftovers, etc., can not be fed, daily feed amount is divided into 3 times, generally each feed does not exceed 3kg, and should be mixed with coarse material After feeding, the amount of concentrate should be controlled at 1 kilogram of concentrate per 3 kilograms of regular milk. In order to facilitate production, milk production should be measured every 3 days, and the rate of milk fat should be measured every 10 days. 2 Full price diet (completely mixed diet) feeding method. According to factors such as milk production, milk fat percentage, and body weight in the early stage of lactation, the nutrients needed by the cows are first calculated, and then the corresponding dietary nutrient levels and the total amount to be adjusted are calculated to determine the feed formula, and then the shorter roughage is obtained. Concentrates, miscellaneous cypress feeds, buffers, minerals, vitamins, etc. are mixed for cattle to eat freely. This will not cause digestive dysfunction, rumen acidosis, overfeeding, etc., and can increase food intake. Balance nutrition and increase milk volume quickly.
