Embodiment 1

[0039] Embodiment 1 fermented feed preparation, pH value and nutrient composition determination

[0040] Feed to be fermented amounts to 4000kg, takes by weighing 400kg corn meal, 900kg oat hay, 2700kg herbal tea dregs.

[0041] According to the mass ratio of the feed to be fermented and the amount of molasses, weigh 80 kg of molasses and dissolve it in warm water at 37° C. to prepare molasses water with a final solubility of 2 to 3%.

[0042] According to the mass ratio of the feed to be fermented to yeast, Bacillus subtilis, Lactobacillus plantarum and Enterococcus faecalis, take yeast, Bacillus subtilis, Lactobacillus plantarum and Enterococcus faecalis powder respectively 1.2kg, 1.2kg, 1.2kg and 0.8 kg was dissolved in 2-3% molasses water, and placed in a 37°C incubator for 2 hours to revive the flora to obtain lysed molasses water. The total number of inoculated colonies of compound probiotics was (1-3)×10 8 CFU / g.

[0043] Take an appropriate amount of warm water at 37...

Embodiment 2

[0056] Example 2 Effect of fermented feed on the growth performance of back-up dairy cows

[0057] In the experiment, 90 healthy back-up dairy cows with similar age (7-8 months), feed intake and body weight were selected and randomly divided into 3 groups, 30 cows in each group, divided into control group, test group A and test group B. The control group was fed the total mixed diet (for the total mixed diet, please refer to the literature "Effects of different feeding methods on milk production performance, nutrient digestion and metabolism of southern dairy cows (Doctoral dissertation). Zhang Shirui, Yi Xuewu, Xiao Bingnan, & Liu Hailin. (2008). "), test groups A and B replaced 5% and 10% of the total mixed diet with the prepared fermented feed respectively. The test time was 40 days in total, the first 7 days were the pre-feeding period, and the formal test was 33 days.

[0058] Growth performance indicators include average daily feed intake, body length, body oblique leng...

Embodiment 3

[0066] Example 3 Effects of fermented feed on the ability of back-up dairy cows to relieve heat stress

[0067] On the last day of the experiment, 15 back-up dairy cows were randomly selected from the three groups, blood was collected by tailbone vein puncture, centrifuged at 4°C and 2500×g for 15 minutes, serum was collected, and stored at -20°C for detection of heat stress proteins, Lactate dehydrogenase, cortisol, creatine kinase, and alanine aminotransferase. The determination of the above indicators was provided by the test kit of Nanjing Jiancheng Bioengineering Research Institute.

[0068] It can be seen from Table 3 that the levels of heat stress proteins, lactate dehydrogenase, cortisol, creatine kinase and alanine aminotransferase in test group A and group B were significantly lower than those in the control group (p<0.05), and in test A Except that the content of alanine aminotransferase was not significantly different between group B and group B, the other four in...

Abstract

The invention discloses fermented feed for improving the growth performance of back-up dairy cattle and relieving the heat stress, and a preparation method and application thereof, and belongs to thefield of animal feed preparation. The fermented feed is prepared by fermenting to-be-fermented feed and molasses with compound probiotics, wherein the to-be-fermented feed includes corn flour, herbaltea residues and oat hay, the compound probiotics include saccharomycetes, bacillus subtilis, lactobacillus plantarum and enterococcus faecalis. The nutritional value of the provided fermented feed can be improved through fermentation of the saccharomycetes, the bacillus subtilis, the lactobacillus plantarum and the enterococcus faecalis. Meanwhile, the color and luster of the feed and the palatability for animals can be changed, the fermented feed is golden yellow, has a strong aroma of liquor and a little fragrance of molasses and promotes animal feeding. The subsequent embodiment shows thatwhen the fermented feed cooperates with daily feed in use in back-up dairy cattle breeding, the growth performance of back-up dairy cattle can be significantly improved, and the heat stress is relieved.

Description

technical field [0001] The invention relates to the field of feed, in particular to a fermented feed for improving the growth performance of back-up dairy cows and alleviating heat stress, as well as its preparation method and application, belonging to the field of animal feed preparation. Background technique [0002] With the rapid development of biotechnology, rich and diverse probiotics are gradually applied to the aquaculture industry. The main application method is microbial fermented feed. First of all, it can not only decompose the macromolecular substances in the feed into small molecular substances that are easy to digest and absorb, but also Some nutritional factors, such as enzymes and vitamins, will be produced during the fermentation process; secondly, after the feed is fermented, it has a strong mellow smell, which has a certain food-attracting effect and can increase the feed intake of animals; moreover, fermented feed can also reduce The crude fiber content ...
