Fodder grass type fermented total mixed ration for dairy cows and preparation method thereof

Abstract

The invention discloses a fodder grass type fermented total mixed ration (TMR) for dairy cows and a preparation method thereof. The fermented TMR is prepared from the following raw materials in percentage by mass in terms of dry weight: 30 to 40 percent of fodder grass, 25 to 30 percent of forage crop silage, 5 to 10 percent of protein feed, 15 to 20 percent of energy feed, 1 to 2 percent of molasses, 5 to 10 percent of food processing by-products, 0.5 to 1.2 percent of premix compound, 1 to 2 percent of calcium hydrophosphate, 0.5 to 1 percent of stone dust, 0.2 to 0.3 percent of common salt, 0.4 to 0.6 percent of sodium bicarbonate and 0.1 to 0. 2 percent of magnesium oxide; wherein the raw materials are prepared into the fodder grass type fermented total mixed ration for medium and high yield dairy cows through the steps of weighing, water content adjustment, mixing, and fermentation after wrapping. A mixed batch obviously improves the quality of a feed after fermentation, effectively improves the feed intake of the dairy cows, improves the palatability and the digestibility of the feed, and can obviously improve the production performance of animals; the fermentation improves the storage performance of the feed, and makes a mixed feed have high aerobic stability, so the feed is convenient for commercialization, storage and transportation, and is favorable for modernized intensive feeding of the dairy cows. The technique has important practicability and application promotion values.

Description

technical field

[0001] The invention belongs to the field of livestock feed processing, and in particular relates to a forage-type fermented total mixed ration for dairy cows and a preparation method thereof. Background technique

[0002] TMR is the abbreviation of Total Mixed Rations (Total Mixed Rations) in English. It is based on the nutritional formula of livestock, and evenly mixes roughage, concentrate, minerals and vitamins such as hay, silage or other agricultural and sideline products containing the required nutrients. A nutrient-balanced ration made from this method, the water content is generally controlled at 35-45%. It is a feed compounding and feeding technology successfully developed in the United States in the 1960s. It has been widely used in European and American countries with developed animal husbandry in the 1990s, and Israel, Japan, and South Korea in Asia also used it earlier. In recent years, some large dairy farms in my country have also begun to us...
