The reproductive performance of dairy cows is directly related to the production level of dairy cows. Many factors are affecting the reproductive performance of dairy cows in actual production, and there are very complex relationships among them, including breed, age, genetic factors, diseases, feeding management, environment, and nutrition. 1. Effect of Energy on Reproductive PerformanceEnergy …

1. Genetic factorsVariety differences. Different breeds of dairy cows have great differences in milk yield and milk fat rate. Compared with local breeds, the milk yield of highly cultivated breeds is significantly higher. Besides, there is an inverse relationship between milk yield and milk fat rate, that is, milk yield of dairy cows is higher and …

1. Influencing factors of calving intervalMany factors are affecting the calving interval in the production of dairy cows, mainly due to inadequate feeding and management of dairy cows, inappropriate breeding environment, poor postnatal care and so on. Dairy cows are cold-resistance and not heat-resistance. Under the high-temperature environment in summer, dairy cows are prone to …

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. 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. 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 …
Frostbite of breast Dairy cows have no hair and the skin is thin, a large area of contact with air, low temperature, strong wind, cold bed and lying on the ground, and improper use of non-winter nipple disinfectant can easily cause frostbite. Frostbite causes chapped breast (head) skin of dairy cows. It is easy to …

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 …
