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 […]
1. Types and Nutritional Value of RoughageRoughage refers to the feed whose crude fiber content in the dry matter of feed is more than or equal to 18%. There are many kinds of roughage which can be used for feeding dairy cows, including hay, straw, greenfeed and silage. Among them, hay refers to Gramineae or […]
1. Enhancing Carbohydrate Digestion75% to 80% of the dry matter and 50% of the crude fiber in the feed are digested in the rumen of dairy cows. There is a symbiotic relationship between rumen microorganisms and host, rumen bacteria and ciliates. It is this symbiotic relationship that determines the ability of rumen microorganisms to digest […]
1. Nutritional managementNutritional management of dairy cows plays an important role in reducing hoof and limb disease of dairy cows. Rumen acidosis is one of the main causes of laminitis. It should be noted that the content of non-structural carbohydrates should not exceed 45%, and the dietary fiber content should be adequate. According to experience, the […]
1. Trace Element AdditivesThere are 7 kinds of trace elements that cows often need to supplement, namely iron, copper, manganese, zinc, iodine, selenium, and cobalt. The application and development of trace elements have gone through three stages, they are inorganic salt stage, simple organic compound stage, and amino acid integration stage. Trace element amino acid […]
1. Physical characteristics of high-yielding dairy cowsIn general, cows with milk yield of more than 7 500 kg, milk fat rate of 3.4%~3.5% and milk protein rate of 3%~3.2% during lactation are called high-yielding cows. The milk yield of individual dairy cows in lactation period is more than 8500 kg, and that of multiparous dairy […]
Ⅰ. Nursing during the Calf Period 1. Prevent calves from sucking each other's nipplesNewborn calves should be raised in a single shed. After feeding, we should wipe their mouths clean to prevent the calves from sucking each other. It is strictly prevented that calves suck each other's nipples. Sucking the nipples of calves can stimulate […]
According to the different stages of milk production and the growth and development of dairy cows, to meet the nutritional needs of dairy cows and achieve the goal of high yield, the nutritional standards of feed in different stages are also different. 1.Dry period (from stopping milking to 15 days before delivery). The main diet […]
1. Q: Early or late feeding of calves is harmful to their growth and health. So the question is, when is the best time to start feeding? A: It is most suitable for calves to start feeding forage at the age of 3 weeks. 2. Q: What is the harm of feeding calves too early? A: Because […]
In the past, dairy farms usually started weaning calves in about six months, with a total feeding capacity of 800-1000 kg. This excessive lactation and prolonged lactation period can achieve higher daily gain and weaning weight, but it not only consumes a large amount of milk and increases the cost, but also has adverse effects […]
