Description

The present invention relates to a method of feeding cattle.

[Conventional technology]

In fattening of beef cattle by the concentrated feed multi-feeding method, the feeding method of roughage (rice straw) is important for improving performance and preventing nutritional disorders. It has been known that, as a method of feeding roughage, it is effective to stabilize the ruminal properties and growth of cattle and to provide uniformity by mixing and feeding with a mixed feed. However, it has not been known how the form of the compound feed at the time of the mixed feeding affects the ingestibility of rice straw to be mixed.

[Summary of the Invention]

The present inventors have found the present invention as a result of examining the form of the mixed feed that affects the eating quality of the rice straw when the mixed feed and the rice straw are mixed and fed to the cow.

That is, the present invention is a pellet having a diameter of 6 mm or less, or a size of 2
The present invention relates to a method of feeding cattle, in which rice straw is mixed with a blended feed in the form of a crushed mash having a size of 200 to 2600 μm, and the mixture is fed to cattle in a ratio of 5 to 20% on an out-of-box basis.

The type of compound feed used in the method of the present invention is not limited as long as it is a compound feed used for cattle. For example, corn, flour, milo, barley, bran, defatted rice bran,
Those containing soybean meal, rapeseed meal, cottonseed meal, molasses, vitamins, minerals, and the like in an appropriate ratio can be mentioned. In the method of the present invention, this compound feed is 6 mm or less in diameter, preferably 4.5 to 6 mm.
Pellets or crushed mashes having a size of 2200 to 2600 μm are used. The size of the crushed mash was measured by the underwater sieving method. If the diameter of the pellets is larger than 6 mm or the size of the crushed mash is out of the above range, the intake rate of rice straw is extremely reduced and the purpose cannot be achieved. The formation of pellets or crushed mashes of a predetermined size can be carried out by using an appropriate apparatus or method used for forming such a shape, for example, a tableting machine, a mixer or the like. For the crushed mash, one containing 50% by weight of half corn is also used.

The rice straw used in the method of the present invention is cut into a suitable length, for example, 2.7 cm, 5.3 cm, 13 cm, 28 cm, or the like. Since the length of rice straw does not substantially affect the intake rate of rice straw in the method of the present invention, any length can be used.

In the method of the present invention, the proportion of the pellets of the above-mentioned size in the form of a coarsely mashed mash and the use of the rice straw is higher than that of the rice straw, and the rice straw is used as an outer part of the diet. 5-20% by weight, preferably 10
It is used in an amount of about weight%. Then, a mixture of the two is provided according to a conventional method.

The method of the invention is applied to cattle, but especially to beef cattle.

〔Example〕

Example 1 Eight dairy steers were used as test cows, starting at 12.5 months (average weight of 510 kg) and ending at 14.5 months (average weight of 5).
80 kg). As for the breeding management system, a group of eight animals were housed indoors, and a kalan individual feeding device was used.

The compounded feed had the following composition. Corn 50% by weight, flour 10% by weight, mylo 10% by weight, barley 10% by weight, bran 5% by weight, defatted rice bran 2% by weight, soybean meal 2% by weight, rapeseed meal 3% by weight, cottonseed meal 1% by weight , Molasses 5% by weight, vitamins and minerals 2% by weight (total 100%)
Wt%; cp 11.5%, TDN 74%). The mixture having this composition was applied to a tableting machine by a conventional method to form pellets having a diameter of 6 mm. On the other hand, as for Inawara, the one cut to 5.3 cm in length was used.

The pellet-shaped compound feed and 10 wt% of cut-away rice straw were added to the compound feed in a feed tank, and the mixture was fed without restriction.

The feeding period was set to 7 days, and the remaining meal was sieved for the latter 5 days, and the intake of each of the compound feed and the rice straw was calculated.

 Table 1 shows the obtained results.

Example 2 In the method of Example 1, 50% by weight of corn corn was blended as a compound feed, and a mash-like (2200 to 2600 μm in size) pelletized without pelletization was used. The procedure was performed except as used.

 Table 1 shows the obtained results.

Example 3 The method of Example 1 was repeated except that the diameter of the pellet was 4.5 mm.

 Table 1 shows the obtained results.

Comparative Example 1 The procedure of Example 1 was repeated, except that 50% by weight of corn corn was blended as a compound feed and pellets having a diameter of 8 mm were used.

 Table 1 shows the obtained results.

[Effects of the Invention] As particularly clearly shown by the data of the examples and comparative examples of the present invention, the intake rate of rice straw (that is, an index indicating how much rice straw was consumed with respect to the mixed feed) was It varies depending on the form of the mixed feed mixed with rice straw, and is preferably a crushed mash having a size of 2200 to 2600 μm or a pellet having a diameter of 6 mm or less. This has nothing to do with the cutting length of rice straw.

When the mixed feed of the form specified in the present invention is mixed with rice straw and fed to cattle, the intake of rice straw that plays an important role in fattening of cattle, such as improving fattening performance and nutritional disorders, is greatly improved. . In addition, by mixing and feeding the rice straw and the compound feed, stabilization and uniformity of ruminal properties and growth of cattle can be achieved.
