Compounding process of granulated lucerne feed capable of increasing milk yield

Abstract

The granulated lucerne feed for milch cow is compounded by mixing corn silage 1.5-4 Kg, barley silage 1.5-2.5 Kg, granulated lucerne block 4.5-8 Kg corn straw 3-5 Kg, barley and corn 0.5-2 Kg and cotton seed pulp 1.2-3.4 Kg. It is used for feeding milk cow and can result in an average daily milk yield of 32-35 Kg, milk producing period over 300 days in relatively lower cost.

Description

1. Technical field [0001] The invention belongs to a feed selection, compounding and feeding method for dairy cows, in particular to a feed selection, compounding and feeding method for main components of alfalfa pellet feed used for increasing the production of dairy cows. 2. Background technology [0002] At present, the feed selection, formula and feeding methods commonly used for dairy cows, some also involve the use of alfalfa and alfalfa pellet feed, but the average daily milk production per cow is only about 20 kg, and the supply of mixed feed is also about 45 kg. The average milk production period is within 250 days. Alfalfa has a digestible protein content of up to 21%, an acidic clean plant fiber content of 29-32%, and a total digestible nutrient content of 52-56%. Its high-protein forage can be used to feed adult dairy cows, while low-protein grass can be used to feed long-term calves. The alfalfa block also saves 10% of forage, saves more than 50% of labor, and h...

Problems solved by technology

[0002] At present, the feed selection, formula and feeding methods commonly used for dairy cows, some also involve the use of alfalfa and alfalfa pellet feed, but the average daily milk production per cow is only about 20 kg, and the supply of mixed feed is also about 45 kg. The average milk production period is within 250 days. Alfalfa has a digestible protein content of up to 21%, an acidic clean plant fiber content of 29-32%, and a total digestible nutrient content of 52-56%. Its high-protein forage can be used to feed adult dairy cows, while low-protein grass can be used to feed long-term calves. The alfalfa block also saves 10% of forage, saves more than 50% of labor, and has no dangerous sundries such as iron wire. The retention time in the body of dairy cows is long, so that nutrients can be fully absorbed. There are also a few cases in which a single industry reaches 28 kg-30 kg or the milk production period is extended, but it is not suitable for general promotion. Through the input-output analysis of dairy cow feeding, the known technology The economic efficiency is low, and there is no stable alfalfa pellet feeding method that can be widely promoted to increase the production of dairy cattle, which directly affects the development and stability of the dairy cattle breeding industry
