Silage orange meal feed and its preparation process

Abstract

The invention provides a silage tangerine pulp feed and a preparation technique thereof. The preparation technique comprises the steps of strain propagation and pomace fermentation. The strain propagation process comprises the following steps: activating Lactobacillus acidophilus freeze-dried powder, culturing, carrying out liquid culture, and carrying out inoculation amplification culture to obtain the Lactobacillus acidophilus strain. The pomace fermentation process comprises the following steps: adding fresh tangerine pulp and rice hull powder into a silage tank, and uniformly mixing until the mass percent of the moisture drops to 50-60%; spraying the Lactobacillus acidophilus obtained in the step (1) on the tangerine pulp / rice hull powder mixture, and pressurizing to compact the material; and repeating many times, sealing the silage tank, and carrying out sealed fermentation to obtain the silage tangerine pulp feed. The silage tangerine pulp feed provided by the invention ensures the nutrient substances and minor elements in the tangerine pulp, and the metabolites generated in the Lactobacillus acidophilus fermentation process can stimulate the reproduction of rumen cellulose bacterium and lactobacillus and perform the function of enhancing rumen microprotein yield, feed digestibility and the like; and thus, the silage tangerine pulp feed has an obvious effect on promoting lactation of milk cows.

Description

technical field [0001] The invention belongs to the field of feed production, and in particular relates to a pomace fermented feed, in particular to a silage orange pulp feed and a preparation process thereof. Background technique [0002] Citrus is the world's largest fruit, and its distribution and production rank first among all kinds of fruits in the world. China's citrus planting area and production rank first in the world. Tangerine pulp is the leftovers after the citrus fruit is processed to make juice or canned, accounting for about 25% to 50% of the weight of the fruit. In recent years, non-frozen juice concentrates (NFCs) have gained in popularity, and a lot of orange pulp has been produced with it. Tangerine pulp is rich in flavonoids, limonene, Vc, carotenoids and other physiologically active components, as well as a large amount of pectin, cellulose, soluble sugar and mineral elements. In China, at present, it is basically disposed of in landfill, and rarely r...

Problems solved by technology

However, there are several technical problems in the silage of orange pulp: (1) the water content of fresh orange pulp is too high, and there are many nitrogen-free extracts, which are very easy to deteriorate and are not suitable for silage; (2) the bitter taste of orange residue limits its direct use as The amount of feed; (3) drying and drying will lose a lot of nutrients such as vitamins, the cost of artificial drying is high, and natural drying is labor-intensive and time-consuming and is easily contaminated by germs

However, pure fermentation technology cannot overcome the high moisture content of orange meal itself, and some harmful bacteria, especially mycotoxins in the raw material of orange meal can cause lesions, so it is not suitable for use as feed
