Lamb early weaning can promote the ewes as soon as possible to restore the body condition, early estrus and breeding, improve the reproductive performance of ewes, to achieve 1 year 2 or 3 years. At the same time, it can also promote the growth and development of lambs and increase the survival rate of multiple lambs, solitary lambs, and weak lambs.
1 Weaning and breastfeeding methods
1.1 Manual Nursing and Weaning Time Lambs began artificial feeding at 7 days of age. 7 to 14 days of age is the period of artificial breastfeeding. Lambs are bred in the same circle as ewes. Lambs can also eat breast milk while they are breast-feeding. Lambs gradually adapt to milk substitutes. 15 to 20 days of age for mother and child segregation adaptation period, lambs and ewes feeding, combined with artificial breastfeeding, control the number of lambs to eat breast milk, the lamb is returned to the ewes every day only to eat 2 to 4 times breastmilk, with increasing age Reduce breastfeeding times. After 21 days of age, the lamb is cut off during the breast-feeding period. The lamb and the ewes are completely separated and fed with artificial milk instead of breast milk.
1.2 Manual breastfeeding methods are commonly used in feeding bottles and milking pots.
1.2.1 The bottle feeding method is to collect the drinking water bottle. After washing and disinfecting, put the good milk (appropriately 40-42 °C) into the drinking water bottle, and put the teat of the same type as the drinking water bottle cap. Bottles of drinking water, then stuffed into the lamb's mouth, trained several times, you can learn to suck milk, or use lambs that have learned to suck milk for demonstration, so that other lambs mimic breast milk. A rectangular wooden rack can be used to make a breastfeeding device. The same number of bottles are fixed on the wooden frame according to the number of lambs in the circle. The breastfeeding device is hung up to a height of 50 cm from the sheep's bed so that the lamb can be sucked up to suck the teat.
1.2.2 The breast-feeding method is to put the milk to the milk pot and put it into the lambs to train the lamb to drink. After breast-feeding for the first time, the lamb is stopped for a period of time. The breeder gently presses the lamb's head and allows the goat's mouth to reach into the basin to drink milk.
1.3 Artificial feeding amount
1.3.1 7 to 14 days of age, feeding 5 times a day (time 8:00, 11:00, 14:00, 17:00, 20:00), every time a lamb is fed 60 mL, the concentration of milk is slightly Higher than the milk powder instructions.
1.3.2 15 to 20 days of age, feeding 4 times a day (time 8:00, 12:00, 16:00, 20:00), each time a lamb is fed 100 mL, the concentration of milk and milk formula concentration .
1.3.3 21 to 35 days of age, feeding 3 times a day (at 8:00, 11:30, and 17:00), each time a lamb is fed 150 to 200 mL, and the milk concentration is slightly lower than the concentration in the milk powder instructions. .
1.3.4 36 to 60 days of age, milk powder is directly mixed in the concentrate at this stage. Every 30 to 40 lambs mix 900g of powdered milk each time and feed twice a day.
1.3.5 After 60 days of age, lambs no longer undergo manual feeding and concentrates and fodder are eaten directly.
2 Precautions
2.1 The time and frequency of regular fixed-temperature Lamb artificial nursing should be relatively fixed. It is necessary to strictly control the feeding volume of each lamb. The milk temperature should be close to or slightly higher than the body temperature of ewes, 40 ~ 42 °C is appropriate.
2.2 Guaranteed cleanliness Lamb breastfeeding equipment must be clean and sanitary. Choose quality and safe milk powder. Every time the milk is fed to the lamb, it must be cashed. After feeding the baby, dry the lamb's mouth with a towel and avoid the lambs feeding each other. Regularly sterilize the sheds, isolate the diseased lambs, and use them separately to avoid mutual infection.
2.3 Prevention of Lamb Lambing Lambs are converted from breast-feeding to artificial breast-feeding, which can easily cause intestinal discomfort and diarrhea. Attention should be paid to feeding volume and milk temperature. Lambs often appear to be diarrhea at the beginning of lactation, but one lactase can be added per 550 mL of milk.
2.4 Lambs are properly weaned at a specific time depending on the season and the body condition of the lamb. If we have a severe reaction to lambs or ewes at weaning, if the weather is too cold or hot, if the lambs are weak, or if we are ill, weaning should not be done.
3 artificial breast-feeding effect
3.1 Raising the survival rate of lambs According to the observation of a successful sheep breeding and early weaning technique at a sheep farm of a goat breeding cooperative in Langzhong City, 378 breeding ewes were able to be stocked in 2014, and 1,097 lambs were born each year (including 2 stillbirths). 21 oysters were killed lately, and the survival rate of lambs was as high as 98%.
3.2 Lamb weight uniformity The artificially nursing lamb is about 60 kg body weight at 60 days, which is basically the same as the body weight of the breast-fed lamb, and the individuals are even, with few lambs, and the lambs grow rapidly after 60 days of age.
3.3 Raising the ewe's breeding rate The lambs were weaned at 21 days of age. The ewe's body condition recovered completely after 20 days of weaning and was re-emotionally mated. It was more than 1 month earlier than breastfeeding, shortening the lambing interval and achieving ewe 1 The annual output of 2 or 2 years of 3 tires greatly improves the breeding efficiency of the ewes.
3.4 Lowering the cost of manual feeding The lambs that are artificially suckled can be fed regularly to reduce the use of concentrates and reduce the cost of raising the ewes. The artificial nursing of lambs improves the survival rate of lambs and the breeding rate of ewes, saving economic costs. â–
