Last year, the price of sheep has risen all the way, and many people have begun to raise sheep. The most important thing for mutton sheep breeding is the management of breeding sheep and lambs, which determines the economic benefits of the farm. Let's talk about the management points of breeding sheep and lambs.
I. Feeding and management of ewes
Nutritional aspect
Nutrient-rich and comprehensive, especially targeted measures, such as injection of sodium selenite VE needle in the selenium-deficient zone, injection of iron-cobalt needle. Nutrition is on the rise. Conventionally, it focuses on increasing energy and proper amount of protein and vitamin supply. It is best to use cooked whole beans and tonic. The large ewes in the recovery period of weaning are focused on increasing the supply of energy feed, preferably rumen glucose. Have poor nutrition. Generally speaking, it has increased from 70% to 90%.
Management aspect
Short-term superior feeding at least one week after weaning. Do a good job in various epidemic prevention, medicated bath, deworming, hoof repair, and hairdressing in advance to minimize stress response. The first is to increase the amount of active exercise, followed by the drive for more than 3 kilometers. In accordance with the ratio of about 1:30, the test rams are placed in a good manner, and the breeding and breeding are carried out in places where the ewe is in sight. According to the seasonal changes, the breeding time is usually changed at 24 solar terms, and the weather is high in wind, rain, snow and cooling. The ewes before breeding should be added to the feed, and then reduced to normal after mating. In the first three months after breeding, the sheep should be reduced by 15%. The high level of nutrient supply will cause a significant decrease in feed intake during the period.
Second, perinatal ewes feeding management
Observed
When eating, resting, ruminating, defecation and urinating, we must carefully observe the situation of the whole group and the individual, and take corresponding measures in time.
Nutritional supply
To be flexible in light of the details of the variety, lyrics, multiple births, and age, you need to pay attention to the following points:
(1) Before the pre-production, the milk is sufficient and the sensation is good. It is not necessary to increase the concentrate when maintaining the body condition; the malnutrition and the multi-lambage should increase the amount of concentrate. It is recommended to add cooked whole beans or special ingredients for milking in the concentrate, and use high-quality forage such as peanut meal, silage, sweet potato, and pasture.
(2) Give plenty of water (warm sugar + bran), digestible forage when feeding lambs, and add alkali microtubules.
(3) The large ewes after lambing start from 100 grams of concentrate per day, return to 500 grams per day after 7-10 postpartum, 600 grams for multiple lambs; 600 grams of concentrate at 11-30 days after birth -800 grams. Suddenly, it is necessary to give 4-6 cm long quality forage. The above increases or decreases according to the amount of milk and the growth of the lamb.
(4) 31-45 days after the lambing, the material is gradually reduced to 300 grams. The corresponding increase in selenium in the concentrate is prepared for weaning and the next stage of estrus; the 46-60 day old concentrate is reduced to 100 grams. Feed the selenium-rich sputum block. The above increases or decreases according to the amount of milk and the growth of the lamb.
Feeding management
Before the birth of the lambs, the fetus was mainly prevented from running, and the lactation was mainly promoted after the lambs were born.
Third, the feeding management of lactating lambs
Nutritional aspect
Rich and comprehensive, to promote growth, anti-diarrhea and stomach growth before exercise. Especially for breeding sheep used for breeding, the breeding rate = money.
(1) Lambs are eaten at 7-12 days of age, initially feeding leaves, high quality alfalfa, and sprinkling a small amount of precision lamb milk powder on the leaves.
(2) After 12 days of age, increase the special pellet feed, and gradually increase the carrot by 100 grams per day. After 18 days of silage, the silage is gradually increased. Add probiotics after 20 days of age. Add 20 grams of soda daily from 20 days to half a month after weaning.
(3) At the age of 30 days, it is more than 250 grams of feed pellets, 250 grams of silage, 100 grams of carrots, and 750 grams of mixed forage (referring to sheep's hybrid sheep and purebred sheep).
(4) Before and after weaning, increase the slag residue, go to the fire and stomach, and multi-layer electrolysis.
Management aspect
Improve the breeding rate and survival rate.
(1) Prophylactic injection of drugs and vaccines: Lambs are injected at a three-day-old age according to the instructions for the injection of sodium selenite VE needles and iron dextran (iron supplementation needles, etc.). Sign the number plate on the three-day-old lamb to prevent premature ear sag and prevent confusion. Weaned after injecting four seedlings at around 50 days of age.
(2) Always observe all aspects of the lamb.
(3) The lamb is broken and the ear tag is bet at the same time. The ear tag is as follows:
a. It is best to choose 7-10 days of age at the age of one; the birth weight of a single lamb is more than 5 kilograms, and it can be as early as 4 days old; double lambs and weak lambs can also be broken at the age of 15 days; long tail sheep 3 It can be broken before the age of the moon.
b. The sheep with large fat tail and short fat tail are not recommended to break the tail, not only the tail is not good, and the storage of energy and the ewes need to have large fat tails for the wintering; the best tail of the slender tail; Hybrid sheep with a cold sheep as the female parent (or a large fat tail and a short fat tailed sheep) should also be cut off.
c. Choose a sunny morning. It is easy to infect the cloudy tail; the frequency of breastfeeding in the morning is high, and the milk in the big goat is also enough. After the tail is broken, the lamb is very painful. After about 10 minutes, it will be numb. Let the lamb find the ewes. Breastfeeding, in order to prevent the lambs from having a greater stress response, especially for mothers with poor maternal and multiple births, should be kept in a single circle for 1-2 days at the end of the break.
d. There is a burning method at the end of the tail, a hemostatic forceps method, etc.----It is best to use a special rubber ring to break the tail. It is really impossible to buy rubber bands (the bicycle's gas line, round tube type, not easy to appear Scars). Be sure to choose a good elasticity, tightly wrapped around the tail in the same position three times, fasten; the elasticity is not good or not fastened, it is easier to swollen infection.
