How to improve the survival rate of lambs
First, do a good job breastfeeding off
Grasp the breastfeeding to ensure the normal growth and development of the lamb. After the lamb is born, first of all, it should be allowed to eat colostrum within one hour of birth; secondly, for the ewes who are born as early as the ewes or with poor breast development, besides the prenatal or postpartum boost feeding, breast warming can be used. The breast massage method promotes breast development to facilitate the secretion of breast milk. Thirdly, for postpartum diseased ewes and emaciated ewe, treatment measures should be taken as soon as possible to promote its early restoration of health; Lambs with excess lambs, lean ewes, and sick ewes should be bred as soon as possible after their lambs are bred with ewes similar in age to their lambs, or artificially breastfed to ensure The normal growth and development of lambs.
Second, the lack of milk for the artificial feeding
Artificial milk for lambs can be used for goat milk, milk, skimmed milk powder or milk replacer. Artificial feeding should be regular, quantitative, constant temperature, qualitative and regular disinfection.
1. Timing. Arrange the feeding time properly. Lambs within one month of age are fed once every three hours; at one to two months of age, they are fed four times a day; at two to three months of age, they are fed three times a day. As the age of the month increases, the number of feedings is gradually reduced, and the amount of each feeding is appropriately increased.
2. Quantitative. The amount of feed is based on the nutritional needs of the lamb. Overfeeding can cause indigestion and even diarrhea. Too little nutrition can affect the growth and development of lambs. The initial period of each lamb is about 250 grams, which can be increased or decreased according to the individual, exercise capacity and age. In general, every day and night, the amount of breastfeeding should not be less than 16% of body weight.
3. Fixed temperature. The artificial nursing temperature should be close to the ewes body temperature, which is about 38 °C better.
4. Qualitative. Feeding lamb's milk, goat's milk, and other milk substitutes requires freshness, cleanliness, access to breastmilk and easy digestion.
5. Regular disinfection. In order to prevent the disease from happening, the utensils should be rinsed with clean water after each feeding and disinfected every 2 days.
Third, grasping feed to promote the growth of lambs
From the age of 2 weeks, the lamb should be properly fed with high-quality green fodder or hay, with a certain amount of concentrated feed. Concentrate formula: corn 40%, bean cake 24%, high quality grass powder 25%, bran 8%, calcium hydrogen phosphate 1%, salt 1%, trace element additives 1%. The amount of concentrate feed supplement should be based on the lamb's age and physical condition. Generally, about 50 to 80 grams will be replenished every day for about 15 days, and 100 to 150 grams will be replenished every day for 31 to 60 days. Daily supplements will be available for 61 to 90 days. Feeding 200 grams, 91 to 120 days of age feeding 250 to 300 grams a day, 121 to 180 days of feeding 350 to 500 grams a day, every day sooner or later each feeding 1 times.
Fourth, prevent diseases and reduce the risk of disease
Lambs have weak resistance, fear of cold, and fear of moisture. They are prone to diseases and infections in the body and outside the parasite. Therefore, a full set of scientific anti-epidemic systems should be established. In general lambs 15 to 20 days old can be subcutaneously injected with sheep epidemic, sheep enterotoxicity, sheep triple vaccine or clostridial disease multi-link dry powder sterilization seedlings, 30 days old subcutaneous injection of foot-and-mouth disease vaccine, 40 days of age Left and right subcutaneous injection of chicken embryo attenuated vaccine, goats infectious pleuropneumoniae aluminum hydroxide live vaccine about 50 days old, about 60 days old intraoral oral injection of apothecary attenuated cell freeze-dried seedlings, about 70 days old back subcutaneous injection Streptococcus suis aluminum hydroxide bacterin, 80-day-old lip mucosa injection of sheep infectious pimple dermatitis live vaccine, 90 days or so intradermal injection of II anthrax bacillary vaccine. After 2 months of weaning, a broad-spectrum, high-efficiency, and low-toxic albendazole (combined with ivermectin) can be used for the first time to repel an amount of 8 to 15 milligrams per kilogram of body weight. Since then, the insects have been repelled on a quarterly basis. It should be noted that the farmers’ immunization, deworming, castration, and colonization of lambs are all great stimuli to the lambs. To prevent the lambs from undergoing intense stress, they should try to immunize the lambs and deworm them. Castration and grouping are performed at regular intervals of 7 to 10 days.
Fifth, timely weaning, prevention of weaning stress
Normally developed lambs are generally weaned at 2 to 2.5 months of age. At this time, the gastrointestinal digestive function of the lamb has already been fully developed and the lamb is weaned. As long as careful care is taken to strengthen feeding, the growth and development of the lamb will not be affected by weaning.
In general, a weaning method is usually used to separate the ewe and lambs. The ewe is moved farther away from the group and the mother and the son can not hear each other. Lambs are still kept in the original sheep house to prevent weaning stress from occurring.
Lamb diarrhoea and slow growth appeared after weaning, which was mainly due to the change of dietary structure that caused the gastrointestinal tract to adapt. Probiotics can be added to the diet to improve gastrointestinal function and prevent diarrhea and slow growth. Hebei Science and Technology News Network
