Ewe feeding and management The ewes must be grazing on pastures with good forage grass growth and excellent grass quality two weeks before the start of the breeding period. Otherwise, they should be supplemented with concentrate to promote normal estrus in the ewe and increase the number of ovulations. Conception rate and litter size. Pre-pregnancy usually does not need feeding, such as feeding only when grazing can not be enough, you can make up for hay. During the last two months of ewes' pregnancy, the growth of the fetus has accelerated and the ewes themselves need to accumulate some nutrients for the lactation period. Therefore, it is necessary to increase the fine material. The feed of pregnant sheep requires no frost, no mildew, various species, rich nutrition, and easy to digest. Postpartum ewes are best fed with warm water. Add some salt and sprinkle some wheat bran to make it regain strength. Lambs cultivating lambs are required to eat colostrum within 1 to 3 days to protect the health of the lambs. If the lambs are not strong enough for the weak lambs or the newly born ewes, they must artificially supplement the milk. Within 1 week, the mother does not raise her husband in circles, after which she can go out and grazing. Before 8 weeks of age, the lambs are mainly breast-feeding, but generally lambs begin training for eating and eating on the 15th or 20th. The half-month-old lamb is replenished with 50-75 grams of mixture every day, 1 to 2 months of age 100 grams, 2 to 3 months of age 200 grams, 3 to 4 months of age 250 grams, and the mixture is crushed beancake, corn, peas Such as the main, it is best not to feed cottonseed cake. The hay is dominated by alfalfa, green grass, peanut pods, and sweet potatoes. Lambs must be weaned by the age of 4 months, on the one hand to restore the body condition of the ewes, and on the other hand to exercise the lambs to live independently. The method of weaning uses more than one weaning method, that is, mothers are separated and no longer gregarious. After weaning, the ewes are removed and the lambs are kept in the original house to keep the lamb as much as possible. A small number of ewes' milk pay attention to crowd out some of them to prevent mastitis. After weaning, the animals were grazing by sex and supplemented with 200-250 g of the mixture each day. Diseases prevent grain acidosis. It is a kind of acidosis caused by sheep feeding or stealing too much grain feed. The onset usually occurs within 4 to 6 hours after the food has been eaten. Acute indigestion, manifested as depressed, abdominal distension, hi lying, also see diarrhea, and soon died. It is necessary to strengthen feeding and management to prevent sheep from stealing food and controlling the amount of feed. Once it is found that the confiscated concentrate is used, gastric lavage can be performed with 5% sodium bicarbonate 1500 ml tube, or gastric lavage with lime water. Intensive rehydration can use 5% glucose saline 500 ~ 1000 ml, 10% camphor sulfonate 5 ml, mixed intravenously. Stomach diarrhea with rhubarb soda tablets 15, orange peel 100 ml, paraffin oil 10 ml, mixed with water, 1 oral. Organophosphate poisoning. More often than not due to eating grazing foods contaminated with organophosphorus pesticides and onset. Treatment will die quickly if not promptly. Strictly bury the pesticide and do not grazing at the place where the organophosphorus pesticide is sprayed. Phosphate can be used for treatment. The dosage is 15 to 30 mg per kg of body weight. It is dissolved in 100 ml of 5% dextrose solution intravenously or intramuscularly with atropine sulfate 10 to 30 mg. Intestinal tuberculosis. The diseased sheep is characterized by intractable diarrhea, weight loss, and anemia, gastroenteritis and edema. Each year in the spring and fall, one insect repellent is performed. 0.05 grams of trichlorfon per kilogram of body weight was mixed with 10% solution. Sulfuric acid diphenylamine, formalin, etc. can also be used. Ascariasis. Those with minor infections showed no symptoms or occasional indigestion. Severe infection can cause diseased sheep to die. Lambs are initially digestive disorders, weight loss, frailty, anemia, edema, dysplasia, hair loss, abdominal distension, and diarrhea. Later, the diseased sheep were weak, and some showed obstruction and death. At the end of the disease, the sheep could not afford to lie down, head backwards, mouth foaming, unresponsive, and finally died. Prevention: The first time the worms were de-wormed between 30 and 35 days after grazing, the second time they were de-wormed 10 to 15 days later, and the adult sheep were de-wormed 50 days after grazing. Sulfodidichlorophenol, flooding spirit, arsenic, and copper sulfate can all be used. Schistosomiasis. It is caused by parasitoids parasitizing in the liver's bile ducts. Acute or chronic hepatitis and cholangitis occur in diseased sheep, which can lead to systemic poisoning and nutritional disorders. Lambs can cause death.
