AI Technical Summary

Problems solved by technology

However, the current feeding of back-up cattle is often limited to short-term interests, blindly reducing the feed cost of back-up cattle, and only feeding the back-up cattle with cheap and poorly palatable roughage or leftovers from lactating cows, which largely affects the Normal growth and development of heifers
In addition, a key problem restricting the development of the dairy industry is that the supply of roughage for dairy cows is relatively short, and the cost of feed is relatively high
Pastures usually use silage corn as roughage for dairy cows, but the supply of silage corn can only be carried out during the corn harvest period in summer every year. The time span from planting growth to harvest of corn is long, and the harvest period is relatively concentrated, which will cause damage to the The harvesting, cutting, and storage of corn are relatively short, requiring a large number of silos, and the long-term storage of corn will also affect the feeding effect of silage corn

Embodiment 1

[0048]

[0049] Add the components in the above-mentioned fermented feed materials 1-5 into the TMR mixer and mix evenly, then add water to the fermented raw materials in the mixer, and adjust the water to 45%-55% of the total mass of the feed; Put it into a polyethylene film vacuum bag, and reach the required density after vacuuming (500-800 kg / m 3 ), and the bag is sealed and finished; after 10-80 days of fermentation, it can be fed to back cattle.

[0050] Each group of raw materials in the above-mentioned embodiment is feed grade, and is conventional commercially available product, and information is as follows:

[0051] Spartina: Harvested in tidal flats in coastal areas

[0052] Barley: Shanghai Dingniu Feed Co., Ltd.

[0053] Premix: Shanghai Dingniu Feed Co., Ltd.

[0054] Medium protein soybean meal: Shanghai Dingniu Feed Co., Ltd.

[0055] Fermentation agent: French Laman company

[0056] Antifungal agent: Shanghai Luyuan Fine Chemical Co., Ltd.

Embodiment 2

[0058] Add the components of the first fermented feed material in Example 1 into a TMR mixer and mix evenly, then add water to the fermented material in the mixer, and adjust the water content to 45%-55% of the total mass of the feed; Fill the feed into the polyethylene film vacuum bag, and reach the required density after vacuuming (500-800 kg / m 3 ), finished after the bag was sealed; fermented for 15 days.

[0059] Laboratory analysis: the same batch of feed samples were sampled reasonably for the 0-day-fermented Spartina mixed feed and the 15-day-fermented Spartina mixed-fermented TMR feed to detect the contents of dry matter, crude protein, crude fat, ADF, NDF and crude ash .

[0060] All detected raw data were statistically analyzed by SPSS17.0. The test results showed that the dry matter of the mixed Spartina fermented feed fermented for 15 days was reduced by 0.91%, the crude protein increased by 0.25%, the crude fat significantly increased by 0.29%, the ADF significa...

Embodiment 3

[0062] The 6-month-old calves in the pasture were measured for their height, body length, chest circumference, and weight indicators. From these dairy cows, cows with similar data were selected for pairing and grouping. A total of 16 eligible 6-month-old calves were selected. The cows were used as the test group and the control group (8 cows in each group), and the calves had free access to water and food. The two groups of cows were placed on the east and west sides of the same ring barn environment.

[0063] Test method: Both the test group and the control group used Example 2, the control group was fed the feed that was not fermented in Example 2, and the test control group was fed the feed that was fermented in Example 2 for 20 days. During the experiment, regular and quantitative feeding was performed, 3 times during the day, and once at night, and the remaining feed was cleaned up the next day. On the last day of the experiment (the 40th day), the bust, body height, body...

Abstract

The invention relates to a TMR (total mixed ration) fermented feed taking rice grass as raw material for replacement dairy cows and a preparation method thereof, the TMR fermented feed comprises the following components in parts by weight: 600-850 parts of rice grass, 40-90 parts of barley, 140-220 parts of auxiliary supplementary materials, 30-60 parts of protein in soybean meal, 8-20 parts of premix, 3-8 parts of fertilizer and 1-5 parts of antifungal agent; and the components are stirred and uniformly mixed by a stirring machine, and then bagged for fermentation treatment, and then the fermented TMR feed for the replacement dairy cows is produced. The TMR fermented feed can significantly improve the palatability of the rice grass and increase the feed nutritional value of the rice grass, the problem that the supply of silage corn in the production of the feed for the dairy cows is tight can be eased by using the rice grass, and the biological invasion type arbitrary growth of the rice grass in the coastal bottomland regions and the ecological environmental crisis caused thereby can be simultaneously eased.

Description

technical field [0001] The invention belongs to the technical field of TMR fermented feed with crops as raw material, in particular relates to a TMR fermented feed for dairy cow back-up cows using Spartina as raw material and a preparation method thereof. Background technique [0002] The concept of Totally Mixed Rations (Totally Mixed Rations) for dairy cows refers to the full-price nutrition of dairy cows designed according to the nutritional regulation technology and the principle of multi-feed matching according to the nutritional needs and feeding purposes of dairy cows in different growth and lactation stages. Diet formula, according to this formula, the various feeds (roughage, silage, concentrated feed and various special feeds and feed additives) fed to dairy cows every day are evenly mixed together through specific equipment and feed processing technology for dairy cows to collect. food feed processing technology. Total Mixed Ration (TMR) technology for dairy cows...
