lamb

Newborn lambs have low immunity and are prone to various diseases, resulting in the death of newborn lambs. The most common causes are as follows:

1. Lamb asphyxia: due to ewe dystocia (intrauterine asphyxia) or lamb inhalation of amniotic fluid, the newborn lamb has only heartbeat and no breathing in a short time (0.5-1 minute), which is lamb asphyxia.

1. Symptoms: newborn lamb, purple lips, wheezing or weak breathing, even no breathing, slow and strong heartbeat or fast or weak heartbeat, irregular heart rate, blistering sound in larynx and trachea, cough, weakness of lamb limbs.

2. Treatment: The respiratory tract obstruction (mucus, amniotic fluid) of lambs can be aspirated by medical intravenous infusion tube, combined with artificial respiration. The practitioner holds the head of the lamb with his left hand and the wrist joints of both forelimbs with his right hand, swinging back and forth with the shoulders as the axis. The rate is 30-60 beats per minute, first fast and then slow, until the lamb recovers breathing. Also available 25% glucose 25 ml, plus vitamin C 0.1 g, 25% nikethamine 0.3 ml, umbilical vein injection.

Second, lamb constipation: 1-2 days after birth lamb meconium difficult.

1. Symptoms: The sick lamb has no spirit, no appetite, hunched back, and constantly moans without feces. Most lambs can see a small amount of black-green meconium outside the anus.

2. Treatment: soft soapy water or warm water can be used to fill the rubber ear washing ball, and then the medical catheter is deeply enema. Oral phenolphthalein laxatives, such as diacetin 1-2 tablets, fruit guide 1 - 2-1 tablets (each tablet contains phenolphthalein 0.1 g).

Lambs pneumonia: Lambs can suffer from pneumonia in utero or after birth, and bronchitis is common. Infection usually occurs before or 2-3 days after birth. The main cause of the disease is poor warmth, cold, weakened body resistance, pneumonia caused by Escherichia coli, Staphylococcus or streptococcal infection.

1. Symptoms: depressed spirit, reduced milk intake, slow reaction, choking cough, foaming at the mouth, rapid heartbeat, shallow and fast breathing, purple lips, even cold all over the body, low or no cry.

2. Treatment: lambs with postpartum disease 3 days, intramuscular injection with kanamycin 0.5-1 ml, twice a day. For lambs more than 3 days after delivery, intramuscular injection of penicillin 200 - 400 thousand units and streptomycin 0.125-0.25 g once a day, or thoracic injection of penicillin, i.e., 50 - 100 thousand units of penicillin solution, injected 1-2 cm into the penultimate 6-8 ribs of the lambs, 4-5 cm away from the middle dorsal line, twice a day for 2-3 days.

IV. Lambs dysentery: It is more common in lambs 1-3 days after birth. The pathogens are more complex. The common ones are Clostridium welchii type B and D, Escherichia coli, enterobacter and Salmonella.

1. Symptoms: There are several kinds of bacteria that cause lamb dysentery, which can be infected alone or in combination. The clinical symptoms are divided into two categories: one is acute onset, showing lethargy, thin saliva in the mouth, weak limbs of sick lambs, lying down, and dying within 2-4 hours. The disease course is slightly longer, showing severe diarrhea, white, yellow or green watery stool, foul smell, purulent mucus and undigested flocculent milk, bloody stool, moaning, hunched waist and abdomen, tensed and heavy, anal incontinence. Mental dull, depressed eyes, exhaustion within 1-2 days of death.

Another kind is sick lamb appetite loss, the condition rapidly worsens, foaming at the mouth, breathing difficulties, mucosal cyanosis, shallow and fast breathing, 60-170 beats per minute, normal or slow heartbeat, 70-150 beats per minute. Gastrointestinal motility weakened or disappeared, visible abdominal distension, abdominal pain and not diarrhea, finally unconscious, body temperature dropped, died within a few hours.

2. Treatment: oral oxytetracycline or intramuscular kanamycin 0.5-1 ml, twice a day. Also available 10% sulfathiazole sodium 5 ml, 25% glucose 50 ml, 0.1% atropine 1 ml, 25% sodium and 0.5 ml, mixed intravenous injection.

The above are several common situations, and different treatment and nursing measures should be taken according to different situations to improve the survival rate of newborn lambs and increase the feeding efficiency.
