Symptoms: Lambs have shortness of breath after birth, obvious rib openings, like to stand, bow their heads and close their eyes, intermittent sucking due to breathing difficulties, and cold nose and mouth. If not treated in time, most people will die after 3 to 4 hours.
Treatment: 20 ml of 50% concentrated glucose injection, 0.2 ml of anaka, intravenous injection once; At the same time, intramuscular injection of penicillin is 50,000 ~ 65,438+million units, with an interval of 4 ~ 6 hours 1 time (if it is cold, the glucose solution and anaka can be heated first and then injected intravenously).
Second, the newborn lamb suspended animation
Symptoms: the lamb doesn't breathe after giving birth, its body is soft, its eyes are closed and its mouth is purple. If they touch their hearts with their hands, they can feel a faint heartbeat and judge it as suspended animation, so they should be rescued immediately.
Treatment: artificial respiration. First clean the mucus in the nostrils and inside and outside the mouth of the lamb, then hold the two hind legs with your hands and hang them upside down. The other hand (or assistant) gently slaps the waist to urge the lamb to discharge mucus from its nose and mouth, then put it on the grass stem on the ground smoothly, and blow air into the nostrils of the lamb with its mouth to stimulate nerve reflex. Then pat the chest gently for 3 ~ 5 times, then hold the two forelimbs with one hand, and hold the two hind limbs with the other hand to open and close inward and outward at the same time, and expand and contract repeatedly until the lamb breathes. At the same time, 0.2 ml of Anaka or Nicodemus injection was injected.
Third, umbilical cord bleeding.
Symptoms: the umbilical cord of the lamb breaks spontaneously after delivery or is pulled carelessly during delivery, and the lamb gradually becomes listless, the conjunctiva is pale and unstable, and then loses blood and coma until death.
Treatment: mainly according to the length of residual umbilical cord rupture. If the umbilical cord bleeds more than ten minutes after the lamb is born, there is still a residual part in the umbilical cord root, and the umbilical cord root can be tied tightly with sterile suture to stop bleeding. If the root of umbilical cord bleeds, the skin around the root of umbilical cord can be sutured and ligated to stop bleeding. At the same time, inject hemostatic and anti-inflammatory drugs.
Fourth, postpartum weak mutton
Symptoms: Lambs with congenital malnutrition are weak after birth, with thin legs and unable to stand. Weak lambs caused by other reasons are characterized by shallow and weak breathing, inability to stretch limbs, lower body temperature than normal, chills in limbs and ear tips, and most of them are in a coma.
Treatment: Take a warm bath first, fill a large basin with warm water of 40 ~ 42℃, wash the lamb's body with warm water, and put the lamb's head out of the basin to prevent the lamb from choking to death. Turn it over from time to time in the shower. When the water temperature drops, pour out a part and then pour in a part of hot water to keep the water temperature at about 42℃. After washing for half an hour, the lamb's mouth became hot, so he opened his eyes to eat milk, that is, dried it and fed it to colostrum in a warm and sheltered place. Two, weak or serious illness, can be injected in warm water bath at the same time 25% glucose 10% calcium gluconate 10 ml. Comprehensive measures should be taken to treat malnourished weak lambs after warm water bath. On the one hand, it is necessary to strengthen the supplementary feeding of ewes and feed more rich and juicy feed from protein to ensure sufficient milk; On the other hand, weak lambs should be supplemented with cod liver oil and human milk powder, or injected with vitamin AD intramuscularly. It should also be carefully fed and breastfed to keep warm and clean, so as to avoid the ewe being abandoned after milking and bathing.
Prevention and treatment of fake death of newborn lamb
Fake death of newborn lamb is also called asphyxiation of newborn lamb. When a lamb gives birth, its breathing is extremely weak or stops, but its heartbeat still exists, which is called suspended animation or suffocation. It is very harmful to sheep industry and directly affects the benefit of sheep industry, so it is of practical significance to strengthen the prevention and treatment of this disease.

1.2 During dystocia, the umbilical cord is compressed, or the fetus stays in the birth canal for too long, sometimes because of inversion and untimely delivery, the umbilical cord is compressed, resulting in circulatory disorders.
1.3 The ewe is sick, the oxygen in the blood is insufficient, and the carbon dioxide accumulates too much, which stimulates the fetus to have respiratory reflex prematurely, so that amniotic fluid is sucked into the respiratory tract. For example, when a ewe is greedy for blood or suffers from severe fever.
Two symptoms
The lamb lay motionless, closed its eyes, stuck out its tongue, turned purple, and even stopped breathing completely. Mucus or amniotic fluid accumulates in the mouth and nasal cavity. Auscultation has wet rales in the lungs. Body temperature drops. In severe cases, the whole body is weak and the reflex disappears, but the heart beats weakly.
3 Preventive measures
3. 1 During the lambing season, strict organizational arrangements should be made, and special personnel must be on duty at night to take delivery in time and carefully care for newborn lambs.
3.2 In the process of delivery, if the fetus stays in the birth canal for a long time, it should be assisted to pull the fetus out in time.
3.3 If the ewe is sick, it should be assisted quickly during delivery to avoid suffocation due to delay.
4 treatment
According to the degree of suspended animation, different first aid measures are taken.
4.65438+ After a short stay, take out the mutton, quickly wipe it with a dry cloth, then wrap the whole body with felt or cotton cloth, open your mouth, wrap your tongue with a soft cloth, and pull your tongue outward every few seconds to restore its breathing action. After the lamb is resurrected, it is put in a warm place for artificial breastfeeding.
4.2 If breathing has disappeared, artificial respiration must be performed after removing mucus and amniotic fluid from nostrils and mouth. At the same time, 0.5 ml of nikethamide, lobeline or camphor water was injected. You can also put the mutton in warm water of about 37℃ to expose the head, spray it repeatedly to the heart with a small amount of warm water, then take it out and wipe it all over the body with a dry cloth.
4.3 Inject 2 ~ 3ml 10% calcium chloride into umbilical artery. The principle of treatment is that different nerve endings are widely distributed on the skin around umbilical vessels and umbilical rings, forming a special reflex zone, which can cause the excitement of the dysfunctional respiratory center in a short time.
No matter which method is used for treatment, we must strive for time as soon as possible. If the treatment is too late, the cerebral cortex cells and other parts of the central nervous system will undergo deep functional changes, and even if physical and chemical stimuli are used, their functions cannot be restored.
What about the "rotten mouth" of lamb before weaning?
Occasional erythema often occurs in the mouth, lip mucosa and gums of non-weaned lambs, which gradually develops into papules or nodules, and then forms blisters or pustules. After that, they fused with each other, and the scab continued to thicken, and part or all of the lips turned out to be mulberry-shaped, and then turned into dark brown scab. This is the so-called "mouth rot". Once the sick sheep are found in the flock, they should be sent to the isolation house with the ewes and cared for by special personnel. The original house and other sheep houses should be disinfected. Generally, the indoor environment, sinks, utensils, walls, etc. should be thoroughly disinfected with a sprayer with poison sand, caustic soda solution, bactericide and cresol soap. Breeders should be forbidden to turn around, and veterinarians should also disinfect them with soap and hand sanitizer. Disinfect the isolation room with caustic soda solution, once a day/kloc-0 (sheep can't be disinfected). The following methods can be used to treat sick lambs: (1) Soak ewe nipples with 0. 1% potassium permanganate, and let lambs drink 0. 1% potassium permanganate water freely. (2) The lamb was injected with polymorphonuclear cell injection, 2mg each time, every other day 1 time. (3) When mutton drools a lot, it can be washed with 2% boron alum water, 2-4 times a day. (4) Apply 0. 1% potassium permanganate solution to the oral cavity three times a day. (5) The second infected person was injected with 800,000 units of penicillin and 20ml of 5% glucose twice a day.
Prevention of pica in lambs
Inadequate forage nutrition is the main cause of pica in lambs. There are two possible causes of pica in lambs: first, ewes are undernourished and lack of forage in the late pregnancy; Second, after the birth of the fetus, the ewe is poorly managed, resulting in insufficient milk, untimely artificial feeding or single supplementary feeding. Therefore, comprehensive preventive measures should be taken to prevent pica in lambs.
It is necessary to meet the nutritional needs of pregnant ewes and ensure the normal growth and development of the fetus. In the late pregnancy, with the rapid development of the fetus, the required nutrients gradually increase. In addition to green roughage, ewes should also be supplemented with concentrated feed. Concentrated feed consists of 40% soybean, 30% corn, 20% barley and 65,438+00% wheat, which are ground into pulp, and then bean cake, 5%-8% bran, 65,438+0% salt and 3%-5% total feed are added. Feed pregnant sheep 2-3 times a day, 50- 100 g each time. In addition, the forage and supplementary feed for pregnant ewes should be fresh and diverse. Such as tender grass, carrots and other green juicy feed.
After the lamb is born, it should be fed with newborn milk as soon as possible. In case the ewe is short of milk, it should be supplemented with emulsion and treated with traditional Chinese medicine. The formula is as follows: 5g of Radix Astragali, 5g of Radix Codonopsis, 0g of Radix Angelicae Sinensis10g, 5g of medulla tetrapanacis, 5g of Rhizoma Chuanxiong, 5g of Atractylodis Macrocephalae, 5g of Radix Dipsaci, 5g of Colla Corii Asini, 4g of Caulis Akebiae, 4g of Eucommia ulmoides, 5g of Semen Vaccariae, 5g of Squama Manis and 3g of Radix Glycyrrhizae, which are ground into fine powder, brewed in boiling water with 20ml of yellow wine as the guide, and at the same time, an emulsion The preparation method of artificial milk is as follows: removing impurities from raw materials, soaking them in warm water of 30-37 degrees for 4-5 hours, removing water after the seed coat swells, and making them germinate; When the bud is about to break through the seed coat, grind it into paste, add 8 times of clear water, boil it for 15 minutes, filter and add 0.5% salt, 4% yeast, 4.5% white sugar, 1.5% bone meal and 0.5% trace element additive (the formula can be referred to as follows: 0.4g copper sulfate, 2g zinc sulfate and potassium iodide.
Improving the quality of goat milk is combined with strengthening the management of lamb feeding. On the one hand, strengthen the feeding of lactating ewes; On the other hand, it is necessary to train suckling lambs to feed in advance to make up for the lack of lactation, and add bone meal and trace elements to the supplementary feed of lambs. At the same time, lambs should graze and bask in the sun properly.
