Embodiment 1

[0022] This embodiment is a proportioning example of the full-price compound feed provided by the present invention. The boar full-price compound feed for improving semen quality is made of the following raw materials in parts by weight, see Table 1:

[0023] According to the above ratio, the corn, wheat bran, soybean meal, and soybean hulls are finely crushed, and the grinder is equipped with a Φ2.5 sieve plate to control the crushing particle size; the crushed raw materials and other raw materials in the formula are first accurately weighed by the batching scale Then enter the twin-shaft paddle mixer together for full mixing, the mixing time is 120s, and the variation coefficient CV≤5%; put the mixed compound feed into the conditioner, and fully mix it under the conditions of high temperature, steam and screw extrusion. Gelatinization; then enter the granulator for granulation, the granulation temperature is controlled between 85-88°C, and finally the degree of gelatinization...

Embodiment 2

[0028] This example is an example of relevant experimental data using the full-price compound feed prepared in Example 1, which is an example of the use effect.

[0029]1. Experiments on the effect on reproductive performance of sows:

[0030] In the experiment, 632 sows were selected and divided into group A and group B, with 316 sows in each group, and two groups of sows were used for breeding respectively. The used semen of group A (25280ml in total, 80ml per sow) is provided by boars (40 heads) feeding the full-price compound feed of the present invention, and group B uses semen (25280ml in total, 80ml per sow). ) were provided by boars (40 heads) fed normal feed. All boars are 18-month-old boars, and they are fed with boar full-price compound feed and common feed of the present invention respectively, and the daily feeding amount is 2.5kg, and after each feeding for 2 months, the semen is taken for the experiment . The test results are shown in Table 2: Group A had 4 m...

Abstract

The invention discloses boar complete formula feed for improving semen quality. The boar complete formula feed for improving semen quality is prepared from the following raw materials in parts by weight: 60-65 parts of corn, 10-16 parts of bean pulp, 3-8 parts of soybean hull, 5-8 parts of wheat bran, 0.5-1 part of nucleotide, 1-3 parts of imported fishmeal, 0.8-1.1 parts of calcium hydrophosphate, 0.6-0.9 part of mountain flour, 0.1-0.3 part of lysine, 0.1-0.05 part of threonine, 0.2-0.4 part of baking soda, 0.01-0.05 part of selenium yeast, 0.2-0.4 part of salt, 0.1-0.15 part of choline chloride, 0.1-0.5 part of N-carbamylglutamic acid and 1-4 parts of boar premix. The complete formula feed disclosed by the invention has the advantages of improving the ejaculatory amount, sperm motility and sperm density of boars and enhancing the heat-stress resistance of the boars.

Description

technical field [0001] The invention belongs to the field of agriculture, and relates to a full-price compound feed for boars and a preparation method thereof, and more particularly relates to a full-price compound feed for boars for improving the quality of semen and a preparation method thereof. Background technique [0002] For a group of pig farms, the impact of boars is far greater than that of sows, because it has more offspring than sows. If the reproductive performance of breeding boars is low, not only will the sows be unable to conceive, but it may directly affect the growth and development of offspring And immunity, etc., seriously affect the economic benefits of the entire pig farm. The reproductive performance of breeding boars mainly includes the quality of semen, the vitality of sperm, the production of semen, the libido of boars, and the age of boars. Among them, the quality of semen is the main index to measure the reproductive performance of boars. In prac...
