When cows are in heat, there are symptoms: cows roaring, walking restlessly, breaking the barn, eating poorly or refusing to eat, high excitement, like to jump on the back of other animals, then stand still for the other cows to jump up, the vulva is slightly open, red-pink, mucus from the vulva flows out like banana sap.
Breeding for cows: Includes 2 methods:
+ Artificial insemination: Using frozen straw semen and equipment to guide artificial insemination into cows. Hybrid calves born by artificial insemination will be more beautiful and larger than using bulls for direct insemination.
+ Using purebred or hybrid Zebu bulls for direct jumping: in remote areas where there is no condition for artificial breeding. The best cow breed is the F2 hybrid bull with 3/4 blood of one of the Red Sindhi, Sahiwal, and Brahman cow breeds.
Care and rearing of reproductive cows and calves
– Care for pregnant cows:
Breeding cows need to be fully fed, every day 30-35 kg of fresh grass, 2 kg of compost, 1 kg of fine feed (corn, bran, …), 25-30g of salt, 30-40 gr of bone meal. Do not force cows to do heavy work such as plowing, pulling carts, etc. People should avoid strongly chasing cows who are pregnant in the 3rd, 7th, 8th and 9th months.

+ Cows are about to give birth with symptoms: Cows have the phenomenon of rump buttock, udder stretch, nipples pointing to both sides, hanging mucus at the edge of the anus, abdominal pain, standing up and lying down, legs scratching the ground, diarrhea, Frequent urination, at the beginning of labor, the amniotic sac comes out first.
+ Midwifery for cows: In the case of cows giving birth normally (pregnancy) there is no need to intervene or just support the cow to reproduce by gently pulling the fetus out by hand. The midwife cuts the umbilical cord 10-12 cm long (no need to tie the umbilical cord), disinfected with 5% iodine alcohol. Wipe down, spread in the nose and mouth of the calf, let the breeding cow lick its own calves.
+ People peel off their nails to prevent their babies from slipping when they first learn to walk.

* For cows:
+ The first 15-20 days after calving, feed the cows porridge (1.0-1.5 kg of concentrate/cow/day) and 25-30 grams of table salt, 30-40 grams of bone meal, with enough young grass Green eat at barn.
+ The next day, during the lactation period, one day feed the cows with 30 kg of fresh grass, 2-3 kg of compost straw, 1-2 kg of bran or mixed feed for the cows to reproduce and restore their health, quickly return to estrus for mating.
* For calves:
+ From birth to 30 days old calves are raised at home, next to the mother cow. Pay attention to keep calves warm, avoid drafts, dry and clean place where calves lie.
+ More than 1 month old, grazing with cows in the yard near the barn, training calves to eat concentrate.
+ Between 3-6 months old: give 5-10 kg of fresh grass and 0.2 kg of mixed concentrate. Practice feeding the calves hay. Calves should be weaned at 6 months of age.
From about 6-24 months old, grazing is the main thing, every day feed 10-20 kg of fresh grass, sugar cane tops, young corn plants. Lack of grass can feed about 2-4 kg more hay a day.
Techniques of composting straw with urea for breeding cows
The digestive system of buffaloes, cows and goats can convert inorganic nitrogen of urea into a source of protein for the body, so it is recommended to apply the method of composting straw with urea to supplement protein for productive cows. High.
– People add salt, urea, lime powder dissolved in water and then use a watering can to spray evenly on dry straw in layers, then incubate the straw in a sealed plastic bag or brick tank. After about 7 days, people gradually feed the cows. The rate of urea is 4kg for 100kg of dry straw.
