Distiller's grains are the direct waste in the winemaking process. Not only does it contain a certain percentage of grain, but it also saves the fine material for cattle. It is also rich in crude protein, which is 2 to 3 times higher than that of corn. It also contains traces of traces. Elements, vitamins, yeasts, etc., in which lysine, methionine and tryptophan content is also very high, which crop straw can not provide. Compared with crop straws, the greatest advantage of distillers grains is the saving of grain; in addition, the coarse grain composition of distillers grains is also higher. Since the distiller's grains are formed after high-temperature cooking after fermentation, its crude fiber content is relatively low, thus destined to distillers grains as the main feed for cattle has good palatability and easy to digest characteristics, there is no indigestion or digestion Incomplete disease, but also can effectively prevent cows from ruminal hernia. Regardless of lees and brewers' grains, they all contain a certain amount of alcohol, and cows are more honest than straws. This is beneficial to the ease of lying and rumination after eating, and has the positive effect of promoting fattening and shortening the rate of slaughter. Feeding cattle to distiller's grains for about 20 days to 30 days will reveal that the cow's fur is brighter and more supple, and food is no longer picky. The on-site determination after slaughter: The cows fed the distiller's grains had better quality, finer fiber, fresh color, and toughness than the unfed beef, and the net meat rate after slaughter was increased by about 3%~5 than that under normal feeding conditions. %, if according to the slaughterhouse reached a point higher than the net meat slaughter point of 8 cents, then an extra 0.24 yuan to 0.4 yuan per catty, if the weight of a slaughtered animal is more than 600 kg to 700 kg for sale, The net profit of each cow is 300-600 yuan. The economic benefit is considerable. Distiller's grain resources are available in all counties and cities, and the price is very low. The author has initially estimated through the feeding practice that the lees leech are about 3 cents to 5 cents per kilogram; the lees are only about 1 cents per kilogram, while the ordinary The price of silage corn stalks that are fed to cattle is about 8 cents to 1 cent. Therefore, conditional cattle farmers or farmers may wish to try. It is worth mentioning that the beginning of feeding cows with lees may have individual cattle reluctant to eat. After a period of 3 to 5 days, the cows are accustomed to the taste of distiller's grains. The proportion of distillers grains is the main reason, and straw is supplemented. The feeding of breweries on the brewers does not have a long food period during the past few days. After feeding cows, they are very fond of eating. This may be related to the natural flavor of breweries. In addition, the distillers grain is not only good for feeding cattle, but it is also the food of geese, ducks and pigs.
