1. Ensuring a comprehensive dietDairy cows in the last 20 days of lactation, to ensure that the loss caused by the previous lactation period can be fully compensated while reserving enough nutrients for the next lactation peak. At this stage, dairy cows should increase the feed of concentrate, absorb enough energy, avoid glycogen depletion during […]
1. Health statusBefore mating, dairy cows must be checked to ensure that they are healthy and disease-free, and their reproductive organs and ovulation physiological activities are normal. Some dairy cows are physically healthy on the surface, but their reproductive organs suffer from diseases such as ovarian inflammation, chronic uteritis and ovarian cysts, which make it […]
Ⅰ. Feeding of Dairy Cows in the High Lactation PeriodThe peak lactation period is the most difficult stage for raising cows, because the lactation is at its peak, and the feed intake of cows has not yet reached its peak. The feeding peak lagged behind the lactation peak for about one and a half months, […]
1. LactationFor newborn calves, amniotic fluid and mucus in the mouth and nose should be cleaned immediately. To ensure that calves can breathe normally, then cut off the umbilical cord. After that, 7% of iodine liquor was applied to the abdomen around the umbilical cord and umbilical cord for disinfection for 3 days, and attention […]
1. Reasonable Control of Concentrated Feed ConsumptionThe nutritive value of concentrate is higher, but it is not that the higher the proportion of concentrate in dairy cow's diet, the better. Although the nutritive value of roughage is higher, its price is correspondingly higher. If the proportion of concentrate in the diet is too high, on […]
1. Do a good job in the preservation of forage leaves The nutritive value of the leaf part of the whole forage is higher. The nutritive components of all kinds of forage grass, hay and straw are higher in the leaves. For example, the nutrients in the leaves of alfalfa hay are much higher than […]
1. Principles of formulation The formulation principle should conform to the Feed Nutrition Composition Table and the Dairy Cattle Feeding Standard, and be combined with the actual production of dairy cows to design the dietary formula. Diet formulation should ensure rich and comprehensive nutrition, a reasonable proportion of concentrate and roughage, so that the nutrition […]
1. Selecting breeds and individuals with high milk fat rateFor different breeds of dairy cows, there are also differences in milk yield and milk composition. Usually, the milk yield and milk fat rate of dairy cows are negatively correlated, that is to say, the higher the milk yield of dairy cows, the lower the milk fat […]
Ⅰ. Colostrum and Its FeedingThere are usually three kinds of calf feed, namely colostrum, dairy substitute, and calf diet. The milk secreted by cows in the first 7 days after delivery is called colostrum. The immune substances in colostrum are immunoglobulin, immunocompetent cell interferon, complement, and lysozyme. 1. Feeding timeAnti-disease substances of newborn calves mainly […]
1. Respiratory problemsGenerally, fever, asthma, cough, runny nose and other respiratory problems (cold) of calves, or more serious pulmonary problems (pneumonia), the main causes of the disease are the low temperature in the cowshed, weak calf physique, and numerous pathogens in the air. Fever abatement or heat clearance and detoxification (such as analgin, antondin, Herba […]
1. Prepare for milkingFirst, the milkman wears overalls. Before milking, he should wash his hands and cut his nails short to avoid damaging cows’ breasts and nipples. Prepare tools for milking, including milk buckets, towels, and buckets for breast scrubbing, filter gauze, etc. Clean up the mattress and the feces in the lying area 1/3 behind […]
Roughage is a kind of low energy and high fiber feed. Staying in the rumen of dairy cows for a long time will stimulate rumination, which is conducive to the normal development of rumen function. Diseases can be caused when concentrate accounts for 60% to 70% of the diet of dairy cows. Roughage plays an […]
