Abstract
The invention provides a fattening nutritional licking brick and a preparation method and application thereof, and belongs to the technical field of animal feeds. The nutrition licking brick for fattening comprises the following components in parts by mass: 70 to 90 portions of salt, 5 to 8 portions of calcium salt, 3 to 8 portions of sodium bicarbonate, 2 to 3 portions of active yeast, 1.5 to 4.5 portions of amino acid and 0 to 5 portions of modified starch; the nutrition licking brick for fattening also comprises a vitamin microelement additive, and the content of the vitamin microelement in the nutrition licking brick is 0.08-3% according to the mass percentage of the effective components. The nutrition licking brick for fattening, provided by the invention, is added with the active yeast, so that the rumen development can be promoted, the digestibility can be improved, and the intestine and stomach health of livestock can be promoted, thereby being beneficial to improving the feed intake and average daily gain, reducing the feed conversion ratio, improving the utilization rate of feed, and enabling the livestock to absorb more nutrition to improve the production performance.
Description
Technical Field
The invention relates to the technical field of animal feed, in particular to a fattening nutrition licking brick and a preparation method and application thereof.
Background
With the rapid development of the economic level of China and the increasing improvement of the living standard of people, the demand of people for high-quality animal products is increasing day by day, mutton is rich in nutrition and fresh and tender in taste, and the high-quality mutton also becomes an indispensable animal product in the life of consumers. Therefore, the sheep fattening industry in China is also unprecedented in development. In a feeding system of the fattening sheep industry in China, in order to meet the characteristics of fast growth and fast fattening of the fattening sheep, the concentrate level is gradually improved in the daily ration proportion. Due to the change of the feeding system, a large amount of volatile fatty acid is generated in the rumen of the fattening sheep, the pH of the rumen is reduced, and a series of adverse reactions and complications such as feed intake reduction, rumen acidosis, foot-lobe disease and the like of the fattening sheep are caused.
The licking brick is a feed for cattle and sheep to lick by processing nutrient substances required by cattle and sheep into blocks through scientific formula and processing technology. The licking brick is designed and produced according to the licking habit favored by the ruminants, and the daily required vitamins such as mineral elements and vitamins of the ruminants are added into the licking brick, so that various vitamins in daily ration can be supplemented to the economic animals such as cattle, sheep and the like which are artificially fed, and the phenomena of pica, hoof disease, retained afterbirth, little milk after the delivery of goats, weak growth of lambs and the like of the ruminants are prevented. However, the existing licking brick does not report on the aspect of improving the gastrointestinal health of cattle, sheep and the like.
Disclosure of Invention
In order to solve the problems, the invention provides a fattening nutrition licking brick which can relieve the intestinal and gastric health of fattening sheep after feeding and improve the feed intake of the fattening sheep.
In order to achieve the above purpose, the invention provides the following technical scheme:
the invention provides a fattening nutrition licking brick which comprises the following components in parts by mass: 70 to 90 portions of salt, 5 to 8 portions of calcium salt, 3 to 8 portions of sodium bicarbonate, 2 to 3 portions of active yeast, 1.5 to 4.5 portions of amino acid and 0 to 5 portions of modified starch; the nutrition licking brick for fattening also comprises a vitamin microelement additive, and the content of the vitamin microelement additive in the nutrition licking brick is 0.08-3% according to the mass percentage of the effective components.

Note: the same column is annotated with any one of the same letters to indicate insignificant difference (p > 0.05), and the same column is annotated without the same letters to indicate significant difference (p < 0.05).
From the table 3, the differences of the feed-meat ratios between the fattening sheep groups are all not obvious from 0 to 15 days (p is more than 0.05); 15-30D, compared with a control group, the feed-meat ratio of fattening sheep in the T1 group and the T2 group is respectively reduced by 4.52 percent and 2.13 percent, wherein the T1 group is obviously lower than the D2 group, and the difference between the T2 group and the D2 group and between the T2 group and the T1 group is not significant (p is more than 0.05); and at 30-45D, compared with the control D2 group, the fattening feed conversion ratio of the T1 group and the fattening feed conversion ratio of the T2 group are obviously reduced (p is less than 0.05), and are respectively reduced by 9.13% and 5.22%. The feed-meat ratio of fattening sheep of the T1 group and the T2 group is obviously lower than that of the D2 group (p is less than 0.05) from 45 th to 60d, and the feed-meat ratio is respectively reduced by 14.36 percent and 8.38 percent.
In conclusion, the fattening nutritional licking brick provided by the invention can promote the gastrointestinal health of livestock by promoting the rumen development, improving the digestibility, finally promoting the increase of the daily gain of fattening sheep, improving the feed intake of the fattening sheep and reducing the feed-meat ratio of the fattening sheep.
Although the present invention has been described in detail with reference to the above embodiments, it is only a part of the embodiments of the present invention, not all of the embodiments, and other embodiments can be obtained without inventive step according to the embodiments, and all of the embodiments are included in the scope of the present invention.
