Jinbao silage cows
Jinbao silage is a green feed that has a moisture content of 65% to 75%. After being chopped, it is fermented by anaerobic lactic acid bacteria in a closed anoxic condition to inhibit the proliferation of various bacteria and keep the forage kept. Juicy state and long-term storage method. Silage odor, soft and juicy, good palatability, rich nutrition, long-term preservation, is one of the important dietary components of herbivorous livestock growth.
First, grasping the silage time is the key.
The harvest time of silage mainly determines the harvest time from two aspects. First, from the appearance, to the field to see the growth of corn, the bottom of one or two leaves of silage plants can turn yellow. Second, judging from the corn kernels, harvesting before grain sowing, the corn straw has a low degree of fibrosis, and the dry matter content is between 22% and 24%. If it is harvested afterwards, the degree of fibrosis of corn stalks will be very high, the nutrition of corn plants will be transferred to corn cobs, the overall nutrition of corn plants will be reduced, and the palatability and nutrition indicators of silage after production will also be reduced.
When making silage, it must be compacted while entering the cellar and compacted with forklifts and chain cars. In this way, the air in the silage can be excluded as much as possible, and the silage can form an anaerobic environment as soon as possible for effective and normal fermentation. Otherwise silage will produce bad fermentation, and eventually mold, deterioration, resulting in waste, causing huge losses to the cattle farm. The tighter the seal, the better the normal fermentation.
Second, the problem should be paid attention to feeding the golden bacon corn silage.
In recent years, due to the lack of experience of some breeders, the nature of the golden silage corn silage has not been fully and systematically understood. Feeding fine concentrates + gold baby silage alone, this kind of rough feed with high moisture content and high acidity makes cows with metabolic disease, The number of acidosis and stomach shift has increased, causing some undue losses to the breeder. Therefore, the following issues should be paid attention to when feeding the golden treasure silage:
1. Jinbao silage, lack of crude fiber and mineral content, especially the lack of crude fiber dry matter, should make full use of its advantages in use, to avoid its own lack of harm to the livestock industry. Hay can make up for its deficiencies. It is recommended that dairy farmers should properly add some hay while feeding the golden baby silage. This will not only fully utilize the benefits of the silico silage, but also produce a healthy and high-yielding herd.
2. When feeding golden gourd silage should also pay attention to the control of the number of multi-liquid auxiliary materials (bean residue, starch residue, brewers' grains, etc.), in feeding these auxiliary materials should increase the amount of hay feeding, control the maximum The amount of feed (within a single dose of 10 kg) can be used to meet the crude fiber requirements of the cow, otherwise the cow will still have problems with dry matter intake.
3. During the period from 0 to 4 months of age, the calf is banned from feeding fermented feed (silage) at this stage. After 5 months of age, the structure of the diet is adjusted to introduce fermented feed and fully mixed diet.
4. Although Jinbao silage has increased energy content per unit, it lacks essential lysine, tryptophan, copper and iron, and vitamin B1 content is insufficient. Therefore, it should be combined with soybean meal or fish meal, bone meal or amino acid additives. Supplementary lack of nutrition.
5. When using the silo reclaimer or artificially layer by layer, the cross-section should be neat, and the sprinkling should be collected immediately after it is taken. Due to the rich nutrition of the golden babe silage, long-term exposure to the air, can easily cause secondary fermentation, so after access to minimize the contact time of the silage with air, to prevent mildew.
In short, the use of gold baby silage, both for the breeding industry and corn growers have a high economic benefit, the cow itself is also a great benefit. Therefore, we should vigorously promote Gumba silage and promote the long-term healthy development of dairy farming.
