Scientific nursing of a newborn lamb

(A) strictly control the birth of the lamb. Confinement workers should do routine work on disinfection and other aspects. For newly-born lambs, they should immediately hold the lamb's mouth, wipe the mouth, nose, and amniotic fluid inside the eye, and move the lamb to the ewes' sight so that the ewes can lick the lambs and promote the shedding of the tires. It is also helpful to strengthen the mother and child. Affection, so that the ewes will soon accept the milk of the lamb. If the first-born ewes are individuals who do not lick the lambs, they can use hay bales and clean gauze to dry the body of the lambs and treat them. For lambs that are suspended in a state of dying after birth, the lamb's hind legs should be shaken in time and the movements are fast and powerful. At the same time, use your finger to hit the heart or try artificial respiration. The specific method is to place the lamb on the back, back on the grass, convert the extension and flexion of the forelimb, and gently press the chest to return it to normal. Under normal circumstances, the umbilical cord of the lamb is self-disconnected. If the scissors are cut off, the scissors can be cut 8-10 cm away from the body surface of the lamb, and then coated with iodide, or soaked in iodine for 1 minute. General healthy lambs start to stand up 15-20 minutes after birth. There are swift movements to find the nipples and sucking milk of the ewes. At this time, the first milk in the ewes' udders should be squeezed out, and the lambs should be brought close. The lambs should be artificially supplemented if necessary. The first breastfeeding. Lambs eat nutritious and comprehensive colostrum is beneficial to the excretion of fetal feces, but also help to promote gastrointestinal motility, and can make the lamb body produce immunity. For the weak lambs in the twin lambs, the lambs are crowded out and the lambs cannot eat colostrum after birth. As a result, they are depressed and unbalanced. The breeder puts his fingers into the lamb's mouth and feels cool (no warm feeling of healthy lambs). The lamb should be warmed immediately. It is best to use the colostrum that has just produced lamb ewes. If there is no colostrum, you can use an alternative method to temporarily save the emergency. Mix 700 g of milk, add 1 egg, 4 ml of cod liver oil and 15-30 g of white sugar, and feed it with a bottle. Before the 1st milking of the lamb, wash the ewes' nipples and their surroundings with lukewarm water, and let the lambs eat the first breastmilk within 1.5 hours after giving birth. Since newborn lambs have limited milking, they should be breast-feeding once every two to three hours. For twins, you should bring both lambs close together and then put the ewes in a single room, put a bucket of warm water and hay, let the ewes quiet for 1.5 hours, and then put the lambs into the room until the mother and child themselves Recognize breastfeeding. (b) The method of lamb transfer. Lambs can be transferred to the general sheep house for 2 to 4 hours after birth. Apply the same number to the side of the mother and daughter before applying the paint. The lambs are placed on the left side and the twin lambs are on the right side. The purpose of the numbering is to make it easy to find out if it is a new mother and child and register for production. Weak lamb can be turned out a few days later. Go to the sheep house can not be fire, but should pay attention to insulation, roof does not leak, the walls are not gaps, it is best to pave a layer of straw or reed mats along the wall, the room temperature is generally 4--6 °C, the sheephouse should be kept dry, no Hall of call, paving the grass evenly. In the sheep house, mothers and mothers are housed in groups, starting from the mother-family group of 7--8 pairs. The age and development of each group of lambs are as consistent as possible. The single-group group of the twin lambs should not be too many. In the same way, the number of heads of weak lambs and mothers should also be adjusted so as to facilitate care. If the herds are too large, the weak lamb cannot find the mother and cannot breastfeed on time, and it is easy to lose weight. When the vast majority of lambs within the mother-family group can quickly find their mothers, the mother-family group can be grouped together two or more, that is, gradually expanding the mother-family group with the growth of the lamb. When the lamb is 20 days old, a mother-family group can be expanded to 50-- 80 ewes. When the temperature is appropriate, let the lamb go out with the ewes. After 7 days of age, it can be outdoors all day. At night or when the weather is not good, it should be indoors. To prevent the lamb lying on the cold ground or in the halls, avoid colds. (c) The basic law of the growth of lambs. Lambs are generally 3-6 months old during lactation, which is the fastest growing period for lambs. For every 1 kilogram of lamb, it consumes an average of about 5 kilograms of breast milk. This means that the average daily weight gain of lambs between the ages of 2 and 2.5 months is 250 to 300 grams. The daily amount of lactating lambs should be 1.2 to 1.5. Rise. The 15-20-day-old lambs rely on breast milk for nutrition and have the fastest growth rate. In order to keep the lambs high and increasing in weight, it is necessary to feed them in a timely manner. In this way, lambs that grow normally during the entire lactation period can grow at a rate of almost three-quarters of the one-year live weight of the year of birth. Lambs can grow to 7-8 times weight in 4 months. Due to the poor adaptability of the lamb, the disease resistance is not strong, the digestive function is not fully developed, only the stomach is developed, and the rumen is very small. Its nutritional methods, from blood nutrition to milk nutrition to fodder, have changed greatly. Therefore, different dietary types, nutritional levels, and management methods have a great influence on its growth, development, and type of physical fitness, and care must be taken. For lambs who have lost or no ewes, milk can be used for artificial feeding. Milk with a high milk fat content should be selected. Fresh milk with less milk fat should not be used before 30 days of age. It is best to use milk from other sheep. Milk temperature is appropriate at about 30°C. He began to feed 5 times a day for 5 days, then reduced to 3 times, 20 days after 1 day 2 times. The amount of feeding is 200 grams of milk for 1--7 days, 300 grams for 7--15 days, 400-700 grams for 15-20 days, and 700-900 grams for 20-300 days (should observe the digestion or bloating of lambs, Symptoms such as diarrhea, etc. (4) Scientific nursing of newborn and weak lambs. In the production of sheep, the hypothermia of the newborn lamb is the main cause of frailty and death. The normal body temperature of the lamb is 39--40°C. Once it is lower than 36°C or 37°C, measures will not be taken soon enough to die. The main reasons for the hypothermia of lambs are as follows: First, the body is not wiped dry within 5 hours after birth, caused by excessive heat dissipation; Second, 6 hours after birth (mostly 12-72 hours) due to lack of milk, resulting in Starvation depletes the body's limited energy reserves and it is difficult to generate the necessary heat energy. Lambs with reduced body temperature should be allowed to return their body temperature to 37°C as soon as possible, and wooden boxes should be used to heat the lambs 120 cm away from the lamb for warming or other measures to increase temperature.
