Look at the colors. High-quality micro-feeds are generally blue-green or yellow-green. If it is found that the color is black or brown, it indicates that the micro-feed has deteriorated and becomes moldy and cannot be used for feeding cows.
Smell the smell. High-quality micro-feeds smell sweet and sour, with a strong wine or pear flavor. If the smell is sour, it indicates that the micro-enough has deteriorated and cannot be fed again.
Touch feel. High-quality micro-feed pellets are soft and moist in their hands. If they are sticky or dry and hard in their hands, the micro-silk feed has become moldy.
Feeding appropriate amounts of cows fed with micro-steer should be appropriate, moderate and appropriate.
Dairy cows with a body weight of 500 kilograms and a daily milk output of 25 kilograms or more may be fed 25 kilograms of microbiologically stored feed and about 5 kilograms of hay each day. Daily milk production may exceed 30 kilograms, and 30 kilograms of micro-alcohol feed may be fed, and about 8 kilograms of hay may be fed. 300 to 400 kg in weight, dairy cows with a daily milk output of 20 kg or more can feed 20 kg of micro-feeds and 5 to 8 kg of hay each day; cows with a daily milk output of 15 kg or less are fed daily with micro-feeds. 15 kg, hay 5-8 kg.
Dairy cows should stop feeding micro-feeds 15 days before milk production and 15 days after birth; dry-milk cows can feed 10 to 15 kg of micro-feeds every day, and pay attention to the appropriate amount of hay; the micro-storage of cattle is raised. Feeding in small amounts is best, preferably within 10 kilograms; young cattle are best fed or not fed.
The feeding method uses micro-storage to feed dairy cows, and strict implementation of the principle of “minimum before, moderate after†feeding.
In the early stages, it should be added in small amounts, and then gradually increased to sufficient quantities to allow the cows to have a process of adaptation so as not to cause excessive micro-meal feed in the rumen of the dairy cow and excessive acidity, affecting the normal feed intake of the cows and reducing milk production.
The pH value in the rumen of dairy cows decreases after feeding micro-alcoholic feed, which can easily cause acidosis. It can add 1.5% baking soda to the concentrate feed, promote gastric motility of cows, neutralize acidic substances in the rumen, and increase the feed intake of dairy cows. Improve digestibility and increase milk production.
Every time feeding micro-feeds should be mixed with hay and then feed the cows to avoid cows picky eaters. Conditional dairy farmers, it is better to feed the whole mixed rations after mixing the concentrate, micro-storage and hay to make a better effect. Microbial feeds or other roughages are best fed 3 to 4 times a day to increase the number of ruminants in the cow.
Frozen micro-feeds must be thawed before they are fed to dairy cows to avoid abortion.
During the feeding process, if dairy cows are found to have diarrhea, they should immediately reduce or stop feeding, check whether the micro-meal feed has mildew or other causes, and resume feeding after the cow is cured. Clean the feed tank every day and add fresh micro-feeds.
Microfeed quality should be guaranteed
Quality Assurance Cows are fed microfeeds to ensure quality. Quality appraisal can use "a look, two smell, three touch" method of identification.
