The bad residue feed is a processing by-product of cereals, beans, and seeds, of which soybean curd residue, starch residue, beet residue, distiller's grains, and brewer's grains are commonly used. The bad residue feeds have great differences in nutrients due to their different water content. Although this kind of feed has low cost and high yield, if the feed amount is not limited, cows are prone to poisoning and affect milk yield.
The crushed fresh residue contains much water, contains a small amount of protein and starch, lacks vitamins, but has good palatability and high digestibility. The bean curd residue is apt to be rancid, suitable for fresh feeding, and the feed amount is controlled to be 2.5 to 5 kg. It is suitable to be fed with green feeding and the effect is good.
Powder residue is a by-product of making vermicelli and starch. The powdered slag produced from raw materials such as corn, potatoes, sweet potatoes, etc. contains mainly starch and crude fiber, and has very little crude protein. The powdered slag produced from peas, mung beans, and broad bean beans has higher protein content and better quality. The cornstarch slag from the pharmaceutical factory has been treated with sulphite solution and is toxic. Do not use it. Powder residue is prone to corruption in the summer and is easy to poison. The daily amount of powder slag should be controlled at 3 to 5 kilograms, which is generally suitable for feeding with green feed and roughage.
Distiller's grains are by-products of the wine industry and have high nutritional value. But can not be fed alone, should be with carrots, grass, bran, fine material with the daily feed volume should be controlled at 3 to 5 kg, too much can cause constipation.
The brewer's grains have high nutritional value. Feeding cows with fresh slag can replace some of the concentrate or high-quality hay, which has obvious milk-enhancing effects. Adult cows are fed on 7 to 10 kilograms a day.
The main component of sugar beet pulp is carbohydrate, low protein content, lack of vitamins, high digestibility of cellulose, good palatability, is conducive to maintaining summer feed intake. However, betaine is contained, which has a toxic effect. Feeding 10 to 15 kg of fresh cows a day should be matched with protein-rich mixes and green fodder.
