Can black goats be fed corn and fine bran? What should I pay attention to?

Generally, when the corn is ripe, the cut corn stalks are chopped and air-dried, or about 20% of the rice bran is added.

Storage. It can also be mixed with a gramaceous family.

Silage mix of leguminous forages. These mixtures are stored in silage or silage bags and are generally allowed to ferment for 40 days (with a minimum of 20 days) before use. This material smells beautiful when taken out, black goat.

On the road of sheep raising, we make progress together, and black goats achieve high yields, which need to be supplemented with concentrate feed, roughage and feed. In feeding, the body metabolism and all physiological activities of black goats, only by supplementing these substances to absorb nutrients, in order to play a better production performance, breeders are particularly important. Long-term sheep with a single food is easy to lack nutrition, and some sheep are thin and unhealthy, weak and sick, and die.

Only when the metabolic function of the sheep is enhanced, so that the healthy development of the sheep is more satisfied, can we better create good benefits for the shepherds.

To improve the growth of black goats, special attention is paid to energy feed. Whether grazing or feeding, adding more than 60% corn to the concentrate that supplements the sheep with nutrients can achieve good results. Corn stover is roughage, and it is not advisable to simply feed dry corn stalk.

Corn straw must be prepared by ammoniation, yellow storage, crushing, crushing and other methods to improve palatability. Corn silage is available if possible.

The palatability of straw is better, and the nutritional value is slightly higher than that of corn straw.

However, it is not advisable to give more; Corn straw also needs to be supplemented with concentrate feed to ensure the ** of vitamins, minerals and nutrients. Otherwise, the feed is single, and the sheep are malnourished.

When conditions permit, sheep should not be fed corn straw alone, but should be fed with green hay, other leguminous straw and other roughage, and supplemented with concentrate. What kind of stock feed do you like to eat for black goats? In actual sheep production, Meng found that black goats prefer foods that contain sugar and dry matter.

For example, feed like silage corn is not very expensive, and they especially like to eat it.

Yes, you must wash all the corn and fine bran, cut it into suitable pieces, and then give it to the black goat, in addition to this, you must pay attention to the reasonable combination of feed, you must choose a good match with coarse grains, and improve the adaptability of the black goat.

Don't just feed. Corn flour should be mixed with other feeds for black goats. Bran feed or green and roughage can be combined. This is conducive to obtaining the nutrients required by the black goats at full price.

Black goats can be fed corn and carefully watched, but it is recommended to give goats more hay and tender grass, which can help them absorb nutrients.

vitamins and water.

1. Energy. All life processes such as respiration, movement, growth, and maintaining body temperature in sheep require energy. Organic matter in feed - carbohydrates.

Both fats and proteins contain energy.

Among them, the carbohydrate is the main source of energy, which includes starch, sugar and crude fiber.

Due to the physiological characteristics of sheep rumen, more high-quality roughage should be supplied to reduce the cost of feeding.

In the past, energy units were often expressed in cards, kilocalories, and megacalories. 1 calorie is 1 gram of water from rising to the required energy. In recent years, research on nutrient metabolism has been mostly used in joules.

is a unit of energy.

The equivalence relationship between card and joule is as follows: 1 card (cal) = joule (j) 1 kilocalorie (kcal) = kilojoules.

KJ) 1 megacalorie (mcal) = megajoules (mj) The energy value of carbohydrates per kilogram of feed is about megajoules, the energy value of fat is about megajoules, and the energy value of protein is about megajoules. The energy in the feed is not fully utilized by the sheep.

The total energy in the feed minus the energy contained in the manure is called digestive energy (DE). This digestive energy is called expressive digestive energy. Manifestational digestion can subtract methane produced during digestion.

The energy excreted by the urine is called metabolic energy (ME).

Metabolic energy is also known as physiological useful energy or expressive metabolic energy (AME). Metabolic energy is necessary for sheep life activities, it has a certain proportion with other nutrients, so when cooperating with high-energy or low-energy diets, other nutrients should also have a corresponding proportion, so that the feed will be economical and reasonable.

Experiments have shown that lambs need about 40 kilojoules of digestion for every 1 gram of weight gained; For every 1 gram of protein gained, it takes about 48 kilojoules of digestion and for every 1 gram of fat deposited about 81 kilojoules.

2. Protein.

Protein is an essential and important component of the sheep body, not only composed of various tissues and organs, but also the main component of enzymes, hormones, antibodies and meat, skin, hair and other products in the body. The nutritional effect of protein is irreplaceable by nutrients such as carbohydrates and fats. Half of the body's proteins are replaced by new proteins in about 6-7 months.

Protein can replace carbohydrates and fats for thermogenesis.

When the above-mentioned thermogenic substances** are insufficient, proteins are decomposed and oxidized in the body to release energy. 1 gram of protein produces kilojoules of heat. It is not economical to replace carbohydrates with protein to produce heat for energy.
