(b) Breeding and laying eggs Female turkeys grow to about 7 months of age, and male turkeys reach sexual maturity at about 9 months of age. Female turkeys enter the first laying cycle from 34 weeks of age. The laying season starts from March to September every year, and every 10 to 15 eggs are hatched. Eggs produce 4 to 6 cycles per year, with 14 to 20 eggs per cycle, and a maximum of 28 eggs. Turkeys are naturally mated and should be protected from inbreeding. When mating turkeys in nature, due to the large differences in weight between males and females, sexual desires are not compatible with each other, making female turkeys vulnerable to damage and thus resulting in the reproduction rate of turkeys. Low, reduce economic efficiency. Artificial insemination can be used to solve this problem. At the same time, the proportion of breeding males can be reduced from 1:4 to 5 for natural mating to 1:30. The cost of breeding for the parent breeding group can be greatly reduced. The method of artificial insemination for breeding turkeys is as follows:
1. Semen turkeys are generally collected by a massage method. They first train the roosters for a period of 2 weeks to make them form sexual reflexes, and then they can collect sperm. The assistant sat on the bench during sperm collection and caught the legs of the roosters with both hands. The feet of the two wings of the turkey chest were massaged rhythmically along the back to the tail and on both sides of the cloaca, and left thumb and other Four fingers support the cloacculae on both sides, and hold the tail feathers by hand; at the same time, use the right thumb and other four fingers to support the abdominal position on both sides of the cloaca to massage rhythmically. When the degraded transfer device is erected from the cloaca, it is squeezed with the thumb and index finger of the left hand to squeeze the semen of the turkey (slightly yellowish-white thick liquid) to flow into the pre-prepared reservoir. (Commonly sterilized clean glass test tubes or collection cups). Every time a male turkey is discharged, 0.2 to 0.3 ml of semen is collected, and the sperm concentration is about 8 billion per milliliter, which is collected once every 3 to 4 days. After semen collection, regardless of whether it is diluted or not, it should be stored temporarily in warm water at 35-40°C. When the sperm collection operation is performed, actions should be avoided to avoid bruising and fecal contamination should be avoided. Contaminated semen should not be used for insemination. The collected semen must be used within 30 minutes in order not to reduce the semen quality and affect the fertilization rate.
2. Insemination In order to ensure a high fertility rate, insemination should be performed in a quiet, clean place at 2 pm in the breeding mother to produce the highest fertility rate. The insemination method uses an inseminator for direct insertion into the vagina. Before insemination, cut the feather around the cloaca with scissors and wipe it clean with saline. The insemination worker's assistant holds the female turkey's legs and the two wing tips with both hands. The insemination fluid needs to be diluted with a dilution factor of 2 to 3 times. Commonly used diluents were physiological saline or 5% 7% glucose or glutamate 2.8 grams, glucose 1.8 grams, distilled water 100 milliliters. The anaesthesia device uses a BCG syringe with a plastic hose and the diluted semen is placed in the syringe barrel. In insemination, the inseminator faces the tail of the female turkey, and the right hand dials its tail plume to the left. The thumb presses the lower edge of the cloaca and gently presses down to open the cloaca, and then the left hand finger inserts the semen into the sperm. Inside the vagina. Female turkey insemination interval: fresh semen is usually about 14 days, diluted semen 8 to 10 days. The input semen volume was 0.025 ml per turkey. After the insemination, the mother turkey is returned to the cage for careful feeding.
The natural mating of turkeys is to be allowed to be bred in time before the mother turkey lays eggs. During the laying of the eggs, the male turkeys should be kept separately so as not to cause excessive harassment of the female turkeys and affect the mother turkey laying eggs. At the same time, in the mating to smooth the sharp claws of the male turkey, you can avoid stepping on the mother turkey, affecting the female turkey and laying eggs.
(C) Egg hatching Turkey hatching of natural fertilized eggs has two kinds of natural hatching and artificial hatching:
1. Natural hatching (mother turkey hatching) The mother turkey has a strong brooding nature. A small amount of breeding turkey eggs can be naturally hatched by female turkeys or local hens. The method is to use a bamboo basket to make a nest for the mother’s fire. Eggs hold hatching. The basket is covered with grass, about 20 to 30 centimeters thick, and then it is put into an egg. The female turkey carries 14 to 18 eggs. When the female turkey hugs her nest, it is in a dim, hidden and secluded place. Female turkeys need to be kept in isolation in order to prevent harassment of hens. The mother turkey should let it leave the sand bath, eat and drink for 2 days. Female turkeys should feed less feed with more water content during the period of egg hunt, and can feed some grain feeds to appropriately raise the standard of feed diets. Eggs were tested and eggs were examined once on the seventh to eighth days, fifteen days, and twenty-five days after hatching to remove lean and dead embryonic eggs. When the eggs are hatched for 26 days, small chicks have already formed in the shell, and some have begun to shell, generally 28 to 29 days can all hatch. Mother turkeys are physically weak and should be fed alone for a few days in order to restore their robustness as quickly as possible.
2. Artificial hatching (incubator hatching) Artificial hatching should be used when breeding turkeys on a large scale. The artificial hatching of turkey eggs requires selection of eggs. The eggs are then placed in an incubator and closed with a formalin solution for fumigation for half an hour. According to the incubator, 20 ml of formalin is used per cubic meter of volume and 8 g is added. Potassium permanganate can be. The temperature of the incubator when sterilized was 30°C and the relative humidity was 65%. After the disinfection was completed, the smoke was immediately expelled, and then officially warmed up to hatch. The incubation temperature was 37°C from the first day to the 25th day and the relative humidity was 56%. After the incubator reaches the requirements, the air holes are fully opened. From the first day of incubation to the sixteenth day, eggs are transferred artificially once every two hours. From the 17th to the 25th days, eggs can be transferred automatically or artificially, once per hour. Incubation was performed on the 8th, 20th, and 25th day of the experiment, and the development of the embryos was examined, and both lean and embryonic eggs were removed. On the 25th day of incubation, the hatching eggs were transferred to a pre-sterilized hatcher. From the 26th to the 28th day, the hatcher temperature was 36.5°C and the relative humidity was 77.6%. In order to increase the humidity of the hatching machine, a wet cloth may be hung in the machine. When hatching, spray the egg surface with warm water of 40-60°C every 2 hours, which is conducive to the hatching of the turkey and enhance its vitality, which can increase the hatching rate.
Breeding turkey breeding techniques
(1) Individual turkeys selected for male turkey selection should be selected as strong, disease-free, tall-bodied, strong male, lively, with shiny feathers, and leg-heavy and straight-leave; breeding female turkeys should be selected Healthy and disease-free, gentle temperament, back flat tail straight, wide chest and large body, feathers, meat, bright color selection. Breeding of chickens for a period of time, purification and rejuvenation, the timely elimination of inferior seed, choose to keep good breeds. It is advisable to use a female turkey for a period of 2 years, while male turkeys can use 3 to 4 years.
