Dairy Cow Fully Mixed Diet (TMR) Technology
The ultimate goal of any feeding method is to hope that the cows can eat the right amount of balanced nutrition at the right stage to achieve the highest yield, the best reproduction rate and the greatest profit. Feeding using a fully-mixed diet (TMR) is the only way of feeding for both large and small herds. The so-called fully-mixed diet (TMR) is a feeding technique that thoroughly mixes raw materials, concentrates, minerals, vitamins, and other additives to provide enough nutrients to meet the needs of dairy cows. TMR feeding technology can ensure that cows eat every ration of diets with full-price diets with stable crude ratio and consistent nutrient concentration on the basis of supporting technical measures and excellent TMR machinery. At present, this mature dairy cow feeding technology has been widely used in Israel, the United States, Italy, Canada and other countries, and China is gradually promoting its use. Compared with traditional feeding methods, TMR has the following advantages: It can increase the milk production of dairy cows. More university studies show that: TMR-fed cows can produce 5% to 8% milk per kg of dietary dry matter; even if milk production reaches With 9 tons per year, there is still a 69% to 10% increase in milk production. Increasing the intake of dry matter in dairy cows TMR technology shortens the roughage and then mixes it with the concentrate so that the material has a complementary effect in physical space, thereby increasing the dry matter intake of the dairy cow. In the case of a well-performing TMR machine with sufficient mixing, it is entirely possible to eliminate the selectivity (daily picking) of the cows for a particular feed, thereby facilitating the maximum use of the lowest cost feed formulation. At the same time, the TMR is completely mixed according to the proportion specified in the diet, reducing the accidental occurrence of trace elements, vitamin deficiency or poisoning. Raising the milk quality The roughage, concentrate, and other feeds are evenly mixed and fed together by the cows to reduce the fluctuation of the pH of the rumen, thus keeping the pH of the rumen stable, creating a good living environment for the rumen microorganisms, and promoting microbiological Growth, reproduction, increase of microbial activity and protein synthesis rate. The conversion rate of feed nutrients (digestion and absorption) increased, the number of cows grazing increased, the digestive disturbance of cows decreased, and the milk fat content increased significantly. Reducing the incidence of cow disease Rumen health is a guarantee for the health of dairy cows. After using TMR, it can prevent nutrient metabolic disorders and reduce the occurrence of nutritional metabolic diseases such as transgastric translocation, ketoemia, puerperal fever, and acidosis. Raising the breeding rate of cows thrown in. When dairy cows at the peak of lactation consume high-energy TMR diets, it is possible to maintain the healthy status of dairy cows without reducing the milk fat percentage, which will help improve the conception rate and reproductive rate of dairy cows. Save on feed costs TMR diets prevent dairy cows from picky eaters. Nutrients can be effectively used by dairy cows. Feed utilization can be increased by 4% compared to traditional feeding models (Brian p, 1994); adequate modulation of TMR diets can also mask feed The adverse effects of poorly palatable but inexpensive industrial by-products or additives can save tens of thousands of yuan in feed costs each year. Greatly save labor time After adopting TMR, the keeper does not need to distribute fine material, coarse material, and other feeds separately, as long as the material can be sent; after TMR, management is easy and management costs are reduced. TMR Feeding Technology Guan Jiandian Management Technical measures are one of the keys to the effective use of TMR, and good management can enable dairy farms to obtain maximum economic benefits. Dry matter intake forecast The theoretical value was calculated according to the relevant formula, and the actual feed intake of dairy cows was derived from the different parity, lactation stage, body condition, milk fat and milk protein, and climate of dairy cows. Reasonable grouping of dairy cows For large dairy farms, lactating herds are divided into early, middle and late herds according to the lactation stage, early dry milk, and late dry cow herds. For dairy cows that are in the early stages of lactation, regardless of the level of yield, the main objective is to increase dry matter intake. Cows with relatively high or very thin milk production in mid-lactating cows should be included in early cows. For small dairy farms, high-yield, low-yield and dry dairy herds can be classified according to milk production. In general, the early lactation and high yield cattle are divided into high-yield herds, and the middle- and late-stage cattle are divided into low-yielding herds. Dairy cow feed formula production According to the actual situation of pastures, formulas are reasonably formulated taking into account factors such as lactation stage, yield, parity, body condition, and feed resource characteristics. Considering the size of each herd, each herd can have its own TMR, or produce a basic TMR+ concentrate (forage) to meet the needs of different herds. In addition, it is critical to be able to thoroughly mix all the rations in the TMR breeding technique, so the ranch must have feed mixing equipment that can be thoroughly mixed. Choice of TMR Stirrer Selection of the choice of TMR Stirrer volume is based on the building structure of the dairy farm, the width of the feed path, the height of the chute, and the entrance of the cowshed to determine the appropriate TMR mixer capacity; the second is The size of the mixer is selected based on the size of the herd, the dry matter intake of the cow, the type of diet (bulk weight), the number of feedings per day, and the mixer fullness. TMR Mixer Model Selection TMR Mixer Selection The best choice for a vertical mixer. Compared with the horizontal type, it has obvious advantages. It requires no additional processing for a bale of straw and long grass. Secondly, it has high mixing uniformity and can ensure sufficient long fibers to stimulate ruminal rumination and saliva secretion; and there is no leftover material in the mixing tank. Difficult to remove the remaining material, affecting the next feeding effect; its four machine maintenance is easy, only need to change the blade every year; its five long life than the horizontal type (15000 times / 8000 times). Choice of TMR mixer production performance When choosing a TMR mixer, we also need to consider the consumption of equipment, including energy-saving performance, maintenance costs, and service life. Among the TMR mixer production companies, the Italian Unistream company is best known. The vertical auger cutting and stirring feeder developed by Unistar has advanced technology, high quality, and high production efficiency, and is far ahead of other countries' similar products in the world. In recent years, in order to meet the needs of different users around the world, Unistream has continuously improved on the basis of the original product, and developed a traction type single cylinder to three-cylinder machine, and a fixed single cylinder powered by an electric motor or a diesel engine. Machine and automatic multi-functional VIRAGE, VANTAGE type products. TMR mixer mixing Notes on the appropriate packing sequence: General vertical mixer is the first rough after the fine, in accordance with the order of hay, silage, bad residue category, fine material added. Mixing time: mixing while adding materials, and then mixing the materials for 3 minutes to 6 minutes to avoid excessive mixing. Material moisture content: In order to ensure that the material moisture content is 40% to 50%, it can be added after adding water or concentrate water. The ranch can conveniently use a microwave oven to measure the moisture in the feed. Trough management keeps daily records. Each day's food intake, dairy appetite, leftovers, etc., in order to promptly identify problems, take preventive measures; ensure that there is 3% to 5% of the remaining amount before each feeding, but also pay attention to TMR day Consistency of the grain in the trough (before/after feeding) and keep the feed fresh every day, push the feed in time. Unique Features of Unifast TMR Mixer Unifast TMR uses a single upright auger bit and a submersible hydraulic drive motor to replace the conventional gearboxes, reducing failure and maintenance costs. The long service life of wearing parts improves the efficiency of the whole machine. Its service life is 2 times to 3 times longer than traditional horizontal ones. It can directly feed long grass, big round bales of grass and even various straws without preprocessing; loading, cutting, Stirring and unloading only takes 25 minutes to 30 minutes/time; the mixing uniformity and agitating effect of the whole mixed feed is much better than the traditional horizontal equipment; the conical agitated tank can guarantee no dead angle and no material remaining. Now Shanghai Guangming Holstein Animal Husbandry Co., Ltd. has become the exclusive agency of Unistar in China, which can ensure fast, rapid and complete after-sales service. Bright Holstein itself is a user of equipment with more than 50 years of dairy breeding experience. From the immediate interests of dairy farmers, according to the actual production needs of the ranch, provide the most suitable TMR mixing equipment for the ranch. In short, TMR technology is the only way for China's dairy cattle breeding industry to become modern and scientific. The research and application of TMR feeding technology abroad have been extensive, and most of them have achieved relatively satisfactory results. Undoubtedly, with the acceleration of the scale, intensification, and modernization of China's dairy cattle breeding industry, a large number of new types of TMR ranches (including the reconstruction of new ranches and old farms) will also appear in China.
