Embodiment 1

[0047] A special granule concentrate for Holstein bulls, which consists of the following raw material components by weight percentage:

[0048] 19% puffed corn, 34% corn, 2.5% bran,

[0049] Secondary powder 7%, soybean meal 23%, puffed soybean 9%,

[0050] Mold can absorb 0.5%, 5% premix 5%;

[0051] Press the above raw materials figure 1 The steps described are prepared, and the specific steps are as follows:

[0052] After the above raw materials are weighed according to the proportion, crushed until the particle size is less than 1mm, fully mixed; transferred to the granulation bin; after being expanded by the expander, transferred to the granulator, and transferred to the cooler for cooling after granulation; after cooling, passed through the crushing screen After crushing, the fine powder and coarse particles are screened out through the classifying sieve, the fine powder is put into the granulator for re-granulation, the coarse particles are put back into the crushin...

Embodiment 2

[0057] A special granule concentrate for Holstein bulls, which consists of the following raw material components by weight percentage:

[0058] 21% puffed corn, 30% corn, 2.7% bran,

[0059] Secondary powder 9%, soybean meal 25%, puffed soybean 7%,

[0060] Mold can absorb 0.3%, 5% premix 5%;

[0061] Press the above raw materials figure 1 prepared according to the steps described. The method of feeding is with embodiment 1.

Embodiment 3

[0063] Thirty-two adult breeding bulls with similar production indicators were randomly divided into test group A, test group B, test group C and control group 1, and a feeding test was carried out for one year. The cattle in the test group were fed with granular concentrates, and the control group were fed with powdered concentrates. The cattle were fed regularly and quantitatively, 3 times a day, and provided with sufficient drinking water. Then, related index detection and calculation are carried out.

Abstract

The invention belongs to the field of feed combination, and particularly relates to a special grain concentrate for Holstein breed bulls. The concentrate is prepared from the raw material components of extruded corn, corn, bran, secondary powder, soybean meal, extruded soybean, mycosorb and 5% premix by mass. The feed is low in cost, reasonable in formula, simple in production and capable of providing various nutrients for growth and development of the Holstein breed bulls, improving the feed conversion rate, promoting the growth of bull semen volume, improving the semen quality, significantlyreducing the breed bull breeding cost and increasing the income of the seed industry.

Description

technical field [0001] The invention belongs to the field of feed combination, and in particular relates to special granule concentrate for Holstein bulls and its application. Background technique [0002] The dairy industry is one of the most intensive breeding industries today, and many countries in the world put the development of the dairy industry in an important position. With the advancement of my country's agricultural structure adjustment, my country's animal husbandry has also been vigorously developed. As a world-renowned high-yield dairy breed, Holstein cattle have wide distribution, strong adaptability, and rich genetic variation within the population. Chinese Holstein cattle, formerly known as Chinese Black and White Cattle, are the only dairy breeds in my country that have been bred through long-term breeding (more than 100 years) by crossbreeding purebred Holstein cattle introduced from different countries with local yellow cattle in my country. In 1987, un...
