How to do a good job of calving, ensure that every cow can be safely and smoothly landed, and minimize the elimination and death of cattle during the delivery process. Let the cows walk out of the delivery room in a healthy way, and welcome the arrival of the lactation period. The healthy growth of calves is an important task for each ranch. To achieve safe production, we should proceed from the following aspects.
First, disinfection work
Cows entering the perinatal period have less resistance to external pathogens than cows in the dry or late lactation period, so disinfection must be strengthened. For example, disinfection of cattle beds is best done once a week, with the use of disinfectants such as acid, alkaline and chlorine preparations. Pay attention to clean the cow bed, cow ditch, etc. thoroughly before disinfection. (Disinfection must be based on a clean and clean foundation).
The cow's nipple should also be disinfected once a day to prevent postpartum mastitis. A 1:4 iodophor solution is recommended.
Promote natural delivery and reduce human intervention. Some statistics indicate that about 70% of cows can give birth without artificial assistance.
When the cow shows symptoms of labor, the cows are driven into the delivery room (note that before using the delivery room must be effectively sterilized, at the same time with a clean, soft dunnage), ranch without a delivery room can be 2-3 The cattle beds were surrounded by railings for a temporary delivery room. Let the cows move freely. People should not interfere too much. However, pay close attention to the whole process of the cow's delivery.
After the cows have calving, do not rush to remove the calf and let the calf stay with the cows in the delivery room. The cows will dry the calf's amniotic fluid for no less than an hour. The advantage of doing so is that it can promote the cow's lactation, but also conducive to the discharge of the placenta.
Second, artificial midwifery
1. Pre-manual inspection
Some cows that cannot give birth naturally must perform artificial midwifery. Before you can give birth, you must know the following:
Whether or not the cow is abnormal, such as whether the body temperature is normal, whether it can stand, whether the disease occurs during the perinatal period, and the condition of the medication.
Check carefully whether the birth canal is abnormal, such as whether the uterus is reversed, whether the soft birth canal has been damaged, and whether the soft and hard birth canal (pelvic cavity) is narrow (the first fetus is more common).
Carefully check the condition of the fetus, such as whether the fetus is alive, whether there is a twin pregnancy, whether the potential, the fetal position is normal, and whether the amniotic fluid is dry or not.
2. Precautions for artificial midwifery
Disinfection, the midwifery's arm (preferably using disposable long-arm gloves), the genital area of ​​the cow, and obstetric equipment required for midwifery must be strictly disinfected. It is recommended to use iodophors, benzalkonium, and other disinfectants that are less irritating to the skin's mucous membranes. Disinfectants that have been used must be discarded and cannot be reused as second midwifery. Used obstetric equipment should be thoroughly cleaned, disinfected and dried.
When more than one person is required to pull the yak vigorously, the direction of force must be the same, and there should be no gap during the exertion.
When you have a fetus that is too large or the birth canal is particularly narrow and does not come out of the birth canal, consider caesarean section. Caesarean section first ensures the safety of the cow, and secondly considers the survival of the calf.
Postpartum treatment can be divided into two aspects: the treatment of cows and the treatment of calves.
3, cow processing
(1) Feed the cows with brown sugar water (red sugar and motherwort warm water) in time. Water should not be too cold, especially in winter.
(2) Observe whether the cow is abnormal, such as whether the placenta is under, whether there is a possibility of uterine ectropion, whether there is abnormal culprit, and appetite, body temperature and so on.
(3) Check for milk early and check for bad milk.
4. Treatment of yaks
(1) The male and female of the yaks must be identified first, then weighed, and the cattle card, number, etc. must be drawn.
(2) For sterilizing the umbilical cord, 5-10% iodine is recommended.
(3) Early feeding, it is best to allow calves to eat their mother's colostrum within 1.5 hours after birth. Pay attention to let the calf eat its mother's milk within one week to improve the calf's immunity and resistance.
When feeding, pay attention to "three settings", namely, timing, constant temperature, and quantitative. After each feeding, the container for the milk is effectively sterilized. Wipe the remaining milk on the yak's mouth with a sterilized towel to prevent transmission of the disease by licking one another.
Glutamic acid, is an acidic amino acid. Molecules containing two carboxyl groups, chemical name for α-amino-pentanedioic acid. Glutamic acid was discovered by lisuoxun in 1856, is a colorless Crystal, fresh, slightly soluble in water, soluble in hydrochloric acid, isoelectric point 3.22. Abound in cereal protein, animal content in the brain and more. Glutamic acid in vivo protein metabolism plays an important role in the process, participating in many important chemical reactions in animals, plants and micro-organisms. Msg containing small amounts of glutamic acid.
Function:
1.Active component for lasting moisturizing and resistance to dry conditions of human skin.
2.Increasing the elasticity of human skin and keeping it tight and smooth.
3.Inhibiting the formation of melanin remarkably.
4.Keeping pH balance of human skin.
5.Forming a slow-release delivery system and therefore improving the absorption capacity of nutrients in cosmetics.
6.As a humectant, moisturizer to improve skin care quality, as a whitening agent, has anti wrinkle property which gives long lasting effect.
