Technical measures to improve the survival rate of puppies
1 Strengthen post-pregnancy management. The survival rate of the puppies and the growth and development rate after weaning have a direct relationship with the basis of the growth and development of the fetus. The fetus has a good growth and development, and after birth, it must have a large body size, a strong body, a high survival rate, and a fast growth and development. More than 70% of the fetus's body weight is developed in the late pregnancy. It is very important to strengthen the rearing and management of females during the second trimester of pregnancy. We must provide sufficient quantities, rich nutrition, strong palatability, and a crude protein content of more than 18%. Diets allow them to feed freely to ensure the normal growth and development of the fetus. If the amount of feed supplied is low, the protein content is low and there is a lack of certain nutrients, it will affect the growth and development of the fetus. The female rabbits were passed on to generations and were forced to use their own nutrients to feed the fetus, resulting in poor motherhood, low birth rate, and low survival rates.
2 carefully arrange prenatal preparation. In production practice, there are frequent occurrences of female rabbits with residual food, puppies with passive dying, falling into the dung and ditch, etc. Prenatal preparation is very important. The following measures can be taken: a. According to the breeding records, 2 to 3 days before the release of the box. The box is packed with soft hay, rabbit hair, etc., dried and sterilized before release, so that the female rabbits can pull the wool nests. b. Maintain a quiet living environment. On the eve of childbirth, it is forbidden to randomly capture and refuse to visit and prevent cats, dogs, and rats from entering cages and avoid sudden shock. c Prepare food. The female rabbits are able to give birth very quickly, usually within 20 to 30 minutes. After the childbirth, she was tired of stomach and was in urgent need of food and drink. If you do not prepare water and feed, you will be forced to eat residual rabbits because of dehydration due to hunger. Therefore, drinking water (such as soymilk, gruel, etc.) is placed in drinking fountains on the eve of delivery, and high-quality mixed feed or radish, sweet potatoes, etc. are placed in the feeding trough. For their free intake. d. Help the female rabbit to pull the hair. Individual mothers born before the birth, do not pull the hair before delivery, only grass filtrating nest, need to help him gently pull part of the chest and abdomen to release the nest, promote its more lactation, protect the puppies. e. Circuit inspections, on the eve of childbirth, special people need to go through inspections and discover accidents and deal with them in time.
3 Try to increase your lactation capacity. After birth, the pups were naked, closed eyes, and lacked the ability to regulate body temperature. 12 days ago, except for feeding, they slept. The growth and development of puppies was fast and the weight increased exponentially. The first week gained 1 time and increased after 10 days. Weight 2 times, 30 days weight gain 10 times. The female rabbit is rich in nutrients, its dry matter is as high as 28.4%, 3 times that of milk; protein is 14%, is 4.8% of milk; 11.28% of fat is contained, 3.5% of milk. Normal female rabbits have a daily lactation amount of 50 to 150 grams. To ensure nutrient supply, a daily supply of protein, minerals, and vitamin-rich mixed concentrates should be provided. Fresh green juicy feeds and herbs should also be added for prolactin. After testing, adding 2% of motherwort, hay, dandelion, Vaccaria and other herbal preparations in the diet can increase the milking power by 29% and increase the weaning weight of weaning rabbits by 25%.
4 Ensure that the pups eat enough milk. To ensure that the young rabbit eats colostrum in time, more milk and full milk is the basis for raising the survival rate of the young rabbit. Find problems in the lactation phase and deal with them in a timely manner.
Female rabbits do not have milk and they are forced to breastfeed. After delivery, check whether the female rabbit has milk or not. If there is milk, the young rabbit is not surrounded by sleep, but is spread out, body is thin, and is dry. A little movement will jump up and make a roar. It is the female rabbit. There are two main reasons for the fact that milk is not fed: First, the mother rabbit is not breast-feeding. Second, she is suddenly scared and jumps out after she is nursing. She is no longer afraid to feed. Forced breastfeeding should be performed immediately after discovery. Grab the female rabbit and gently place it in the farrowing box so that the rabbit can suckle. After the animal is eaten, remove it. After several trainings, the female rabbit can breastfeed itself.
If there are too many farrowing babies to be fostered, the female rabbit usually has only 8 nipples. If there are more than 8 litters in a litter, the female rabbits will be weak and have little milk production, and feeding the whole litter will be difficult. The female rabbits are breast-feeding once a day and night, and are breast-feeding for about 3 minutes each time. Strong and timid rabbits can eat milk every time, weak rabbits can't eat, and the differentiation of strong and weak rabbits occurs. The small rabbits were transferred to the nest of another female rabbit with a close delivery date, a few litter size, a strong body, and a large amount of lactation. However, because the foster female rabbit is sensitive to the smell and can sniff out the pups that are not their own, they will not only bite the pups and bite the pups. Therefore, when they are fostered, they need to use the urine of the foster mother rabbit to wipe them on the foster rabbits. It can't smell like another nest of puppies. If the female rabbit has too little calving, the young rabbit can be fostered to breed it as soon as possible.
If the rabbits are not equal in strength, they should be breast-fed in stages. If the female rabbit has too many litters, different sizes, and can't find a suitable foster female rabbit, breast-feeding can be carried out in stages, that is, a group of weak and weak rabbits can be divided into one group and then breast-feeding. After breastfeeding, artificial control allows the rabbit to eat more milk.
Female rabbits are milkless and have to breastfeed artificially. After the childbirth, the female rabbit is milk-free and can be artificially breast-fed if she cannot find her foster female rabbit after accidental death. After connecting the valve core hose to the syringe or eye cup for cleaning and disinfection, the inhaler boils the milk to a temperature of 38 to 390C (adds 1.5% fish oil and a moderate amount of fresh egg yolk) and feeds 1-2 times a day. .
5 Thorough prevention of deadly diseases. The most susceptible diseases in the rabbit stage are yellow urine and sepsis septicemia. These two diseases are also the most deadly diseases in the rabbit stage and must be thoroughly prevented.
Yellow uropathy occurs when a puppies eats milk from a mastitis-infected female rabbit due to staphylococcal infection. Early onset of acute enteritis. And then discharge yellow urine-like dilute feces, contaminated around the anus, hind hair wet, stench, sick rabbits drowsiness, the body is soft and thin, the course of 3 to 4 days, the mortality rate is high. The autopsy showed a large area of ​​hemorrhagic inflammation in the small intestine and rectum. The diagnosis was based on the symptoms of the pups and the presence or absence of mastitis in the examined female rabbits. The septic sepsis in pups is caused by stab wounds on the body surface of the rabbit or after eating milk from mastitis-infected rabbits infected with Staphylococcus. After the illness, inflammation occurs in many parts of the body such as the back, abdomen, chest, etc., showing miliary white pustules, a thin body, and a high mortality rate. According to female rabbits have mastitis or buns on the surface of the wound and the occurrence of pox sores can be diagnosed.
Once the onset of the disease should be immediately stopped feeding, artificial nursing or foster care and treatment as soon as possible. In the case of bacteroid pox sores, iodine tincture can be applied to the affected area, with a 0.1% streptomycin solution bath, bath twice a day, even bath for 3 days.
In addition, preventive work must be done. While strengthening the daily scientific feeding and management, we must pay attention to keeping cages and sports venues clean and hygienic, and regularly disinfect and eliminate sharp objects. Put soft, clean and dry grass mats in the farrowing boxes. The cages should be large enough to prevent overcrowding and fighting and biting each other. The female rabbit can be added erythromycin in the feed before delivery, and each rabbit is fed 1 gram per day.
6 to prevent lifting hanging milk to death. "Suspended milk" means that there are too many puppies and they do not eat enough. When the baby sucks, the baby does not rest on the nipple. Under normal circumstances, the female rabbit breast-feeding 3 to 4 minutes after the jump out of the nest, and when the sudden breast-feeding when they are breast-feeding or suffering from breast pain caused by sucking rabbits immediately jump out of the litter box, will be close to the nipples Rabbits are brought out of the box. Out of the nest means that the litter box is not solid or is bitten by the female rabbit. When the female rabbit has less milk, more calving, and has less food, the puppies go to the farrowing box for crawling around.
7 Avoid cold and heat to ensure proper temperature. The pups were naked, closed eyes closed, and lacked in the ability to regulate body temperature from birth to 12-13 days of age, and their body temperature changed as the outside temperature changed. Although the outside temperature required for puppies is higher than that of rabbits, if it is higher than 35°C, it may cause heat stroke. And below 16 °C will be frozen, so cold and summer is an important work of the puppies (especially 12 days before) stage.
In the cold season, the farrowing box has higher insulation. To choose good insulation materials, hygroscopicity mats. Such as the bottom of the box into the plastic foam, disinfection of the poultry hair, rabbit hair, soft grass and so on. After separation, the mother is removed and the young rabbit is moved into the greenhouse for daily manual feeding. In the hot season, precautions should be taken to prevent heatstroke. The entire rabbithouse should be shaded outside (such as shade sheds, trees, etc.), with doors and windows open for ventilation; the farrowing box should be moved to a well-ventilated place; and the farrowing box should be removed. A part of the rabbit hair, to install electric fans, underground housing can be built conditions, the transfer of the mother to the underground rabbit house best.
8 Reduce accidental casualties. The main causes of accidental injuries in production are: stuck to the hind leg or neck by the pedals, and then being stamped and stamped by other puppies and mother rabbits to cause injury or death; the larvae and sweet potato stalks that are fed are wrapped around the hind limbs; Doors, windows, and grass racks are not tight, and the puppies are squeezed and drilled outside. They are injured by falls; the management is lax and the sense of responsibility is not strong. The pups are placed in the wrong cage and bitten by the mother rabbit; in addition, it will happen. A bite by a rat killed or even the entire nest was taken away. According to the causes of accidental casualties, regular inspections will be made to trim cage doors, windows, pedals, partition walls, training and rabbit-raising technicians, and to strengthen daily scientific feeding management and eliminate mice, so as to reduce or eliminate accidental casualties.
9 early feed to ensure development. As the younger rabbits increase their food intake as they age, the supply of breast milk is in short supply and they need to be fed in advance. Under normal circumstances, puppies did not start feeding until 17-18 days of age. Eat very little at the beginning, just eat some soft leaves, leaves and other easy to chew the digested feed, then gradually increase. Need to provide nutritious, palatable, easily digestible, protein content of more than 20%, crude fiber content of less than 10% of the quality of feed, and need to add the right amount of yeast powder, auxin, vitamins and charcoal powder, fried sorghum noodles, quinoline Ethanol, oxytetracycline, etc. It can ensure normal growth and development, but also can prevent diarrhea, coccidia, Pasteurella, gastroenteritis and other diseases.
10 Wealing must be done in a timely manner. The normal weaning time in production was 28 days and 42 days. If the "blood matching" is conducted with frequent breeding, it must be weaned before 28 days of age, and weaned at 42 days except this time.
There are two methods of weaning: one-time weaning and batch-wise weaning. In the case of pups whose growth and development are even and tidy, the female rabbits have no milk, and the body is very thin, etc., one-time weaning is used, that is to say, all the mothers are separated and then have different nests, and weaned in batches. The female rabbits are strong and have more milk in the breasts. There are many different types of puppies, and the size of the rabbits can be divided into batch weaning methods. The roughly strong puppies will be weaned first, leaving the thin and weak to continue feeding. After a few days of breast milk, the female rabbit has a lot of milk after it is separated. In order to prevent the occurrence of mastitis, part of the weak young puppies are put back into the original cage and eaten several times.
Weaning is an important juncture in a rabbit's life. After weaning, it depends entirely on feed to provide nutrition, and its ability to resist the external environment and diseases is still relatively low. If we do not strengthen feeding and management, the earlier weaning, the higher the mortality, so except under special circumstances. , must be weaned before 28 days of age, other females can wean properly early or wrong; practice shows that the use of weaning after leaving the original rabbithouse is better, because the environment, the temperature is the same as the original, The stress response can be reduced, and the survival rate is higher than that immediately transferred to a new place; in order to prevent the occurrence of mastitis in female rabbits, the supply of concentrate and succulent feed should be reduced on the eve of weaning, and drinking water should be controlled to supply more quality hay.
