[0033] Based on the fermented complete mixed ration for dairy cows provided above, the present invention further proposes a preparation method of the fermented complete mixed ration for dairy cows, figure 1 Shown is an embodiment of the preparation method of the fermented complete mixed ration for dairy cows provided by the present invention. see figure 1 As shown, in this embodiment, the preparation method of the fermented complete mixed ration for dairy cows comprises the following steps:

[0034] Step S10, mixing food processing by-products, forage grass, energy feed, protein feed, premix and molasses, and adjusting the moisture content to 45-55% to obtain a mixture;

[0035] Step S20, adding fermentation additives to the mixture, and sealing and fermenting after mixing to obtain a fermented complete mixed ration for dairy cows.

[0036] The by-products of food processing, forage, energy feed, protein feed, premix and molasses are mixed uniformly according to a predetermi...

Embodiment 1

[0043] (1) The composition of basic raw materials in the fermented complete mixed diet for dairy cows is shown in Table 1, and the amount of calcium carbonate added is 1.5% of the total mass of the basic diet.

[0044] Composition and nutrient content of fermented complete mixed diet for dairy cows in Example 1 of Table 1

[0045]

[0046] In Table 1, *nutrient composition is the content in dry basis; in each kilogram of the premix, vitamin A≥320000IU, vitamin D≥50000IU, vitamin E≥1500IU, zinc≥5g, manganese≥5g, copper≥1g, Iron ≥ 8g, iodine ≥ 0.08g, selenium ≥ 0.02g, cobalt ≥ 0.03g; sweet potato beverage residues were taken from a fruit and vegetable beverage factory in Hebei Province, with a water content of 75-85%.

[0047] (2) Preparation of fermented complete mixed diet for dairy cows:

[0048] Mix the alfalfa hay, corn meal, soybean meal, sweet potato beverage residue, molasses, and premix evenly in proportion, adjust the moisture content to 45-55%, and form a mixture,...

Embodiment 2

[0050] (1) The composition of basic raw materials in the fermented complete mixed diet for dairy cows is shown in Table 2, and the amount of calcium carbonate added is 0.5% of the total mass of the basic diet.

Abstract

The invention discloses a fermented total mixed ration for dairy cows and a preparation method thereof, the fermented total mixed ration for dairy cows comprises a basic raw material and a fermentation additive, the basic raw material comprises the following components by mass: 45-55% of food processing by-products, 20-30% of forage grass, 10-20% of an energy feed, 5-10% of a protein feed, 1-2% of a premix and 1-2% of molasses; the fermentation additive comprises calcium carbonate, and the mass of the calcium carbonate is 0.5-1.5% of the total mass of the basic raw materials. The fermented total mixed ration for dairy cows provided by the invention has the advantages of good fermentation quality, pH of 4.4-4.6, moderate acidity, improved aerobic stability and good palatability, and is beneficial to increase of dry matter feed intake of dairy cows.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a fermented complete mixed ration for dairy cows and a preparation method thereof. Background technique [0002] Total Mixed Ration (TMR) is a scientific and reasonable dietary formula designed according to the nutritional needs of dairy cows at different production stages and the nutritional value of feed materials. into a nutritionally balanced diet. At present, most large-scale dairy farms use corn, soybean meal and other concentrated feeds, silage, hay, straw and other roughages and high-moisture residues as the main raw materials to prepare TMR, and adjust the moisture content to about 50%. Studies have found that TMR prepared in this way starts to heat up and undergo aerobic deterioration within 12 hours after preparation due to its high moisture content. The aerobic deterioration of the feed not only reduces the nutritional value of the feed, causing serious feed was...
