How to Prepare Beef Concentrate
Beef cattle are mainly based on roughage, but roughage can not meet their nutritional needs, need to feed concentrate feed. The comprehensive nutrition of concentrate feed directly affects the growth and development of beef cattle. Here are some things to keep in mind when preparing beef concentrates:
First, the preparation of concentrate feed
Concentrates include energy feeds, protein feeds, mineral feeds, trace (constant) elements, and vitamins.
1, energy feed is mainly corn, sorghum, barley, etc., accounting for about 60% to 70% of concentrate feed.
2. Protein feeds mainly include bean cakes (粕), cotton cakes (粕), peanut cakes, etc., accounting for about 20%~25% of concentrated feed. Yak feed, young cattle fattening can add 5 to 10% bean cake (粕). The maximum daily feed amount of soybean cake (broth) and peanut cake should not exceed 3 kg.
3, mineral feed, including bone meal, salt, baking soda, trace (constant) elements, vitamin additives, generally accounting for 3% to 5% of the amount of refined feed. The amount of young cattle fattening bone meal accounts for about 2% of the amount of refined feed, and shelf-fat fattening accounts for 0.5% to 1%. Winter, spring and autumn dietary supplements account for 0.5% to 0.8% of concentrate feed. When using distillers grains as the main roughage, baking soda should be added, and the amount added should be 1% of the amount of concentrated feed. When other roughage feeds cattle, 0.3%-0.5% of the amount of concentrated feed can be added in summer.
4, trace (constant) elements, vitamin additives generally can not be their own preparation, need to purchase from the regular manufacturers, in accordance with the instructions during the use of the period, is strictly prohibited the use of "three no" products.
二ã€Precautions for preparation of concentrate feed
It is forbidden to add additives, sex hormones, protein assimilation hormones, psychotropic drugs, antibiotic filter residue and other drugs that are not allowed to be used by the country. The additives and drugs allowed by the State must be strictly added in accordance with the regulations, and the use of meat and bone meal is strictly prohibited. The moisture content in feed must not be increased. More than 14%.
Third, grain feed fattening cattle
Mixing fine and rough feeds in proportions to produce whole-grain granules for feeding fattened cattle can increase weight gain, reduce feed wastage, significantly shorten the feeding time of experimental cattle, shorten labor time and labor intensity of workers, and increase labor quotas. Reduce the cost by a small margin. Reference formula: cornmeal 47.5%, bran 5%, cottonseed cake 10%, additive 1%, salt 0.5%, bone meal 1%, wheat straw powder or grass powder 35%.
Plant Extract has been classified to two types by extraction methods including the standard plant extract and ratio extract in china local market. If we want to distinguish between the two types ,we can see from the ingredients that we should pay attention to. The standard plant extract will be tested of its special ingredients that in the product maybe by HPLC, UV, TLC etc,but for the ratio extract,we don't pay attention to the special ingredients that in it or not,not to mention the purity of one ingredient.if you still confused about the cllasfication,pls contact us to know more.
