Description

[Detailed description of the invention]

The present invention relates to feed for livestock and poultry. In livestock management such as livestock and poultry, there are many difficulties in dealing with manure. For example, in the case of broilers, currently all-in group rearing is carried out using free-range farming.
Although we use the all-out method, the current situation is to leave the feces on the floor and dispose of them all at once after the broilers are shipped, and if the feces are soft, there is a risk of the leftover feces drying out. This has become a major problem in terms of hygiene management. Also, pigs,
Even in the breeding of egg-laying hens, soft feces are difficult to turn into fertilizer or incinerate, and are not desirable in terms of sanitary management. Under these circumstances, the present inventors discovered that if dietary leaf iver obtained from corn husk, wheat bran, or rice bran is mixed into feed, it is possible to prevent soft stools in livestock and poultry. The invention has been completed. That is, the present invention is a feed for livestock and poultry characterized by incorporating dietary leaf iver obtained from corn husk, wheat bran, or rice bran, and its purpose is to prevent loose stools, Moreover, the aim is to provide feed with good feed effects. The dietary leaf iver obtained from any of corn husk, wheat bran, and rice bran to be mixed in the present invention is mainly composed of cellulose and hemicellulose, and is obtained by enzymatically treating the bran of cereals such as corn husk, wheat bran, and rice bran. It is obtained by removing part or all of starch, proteins, lipids, inorganic substances, etc. by chemical treatment, physical treatment, or a combination of these treatments. As the enzyme treatment method, for example, a method is adopted in which one or more of starch-degrading enzymes, proteolytic enzymes, lipolytic enzymes, and fibrinolytic enzymes are added under conditions of approximately PH 3 to 9 and temperature of approximately 30 to 100°C. be done. Examples of starch degrading enzymes include α-amylase and glucoamylase, proteolytic enzymes include protease, lipolytic enzymes include lipase, and fibrinolytic enzymes include cellulase. As a physical treatment method, for example, grain bran is crushed with a crusher such as a homogenizer or a hammer mill,
A method is adopted in which starch, proteins, lipids, inorganic substances, etc. are removed by sieving. Chemical treatment methods include, for example, adding an aqueous solution of mineral acid or organic acid to grain bran and heating it under conditions of pH 2 to 5, or adding a food grade surfactant and heating it under conditions of pH 3 to 8. A method of heat treatment is adopted. Monoglyceride, sugar ester, etc. are used as the food-grade surfactant. The amount of cellulose, hemicellulose, etc. contained in the dietary leaf fiber prepared as described above varies depending on the raw materials used and the processing method, but as NDF (Neutral Detergent Fiber) (neutral detergent treated fiber) % or more is desirable. Here, NDF (Neutral Detergent
Fiber) refers to the content of cellulose, hemicellulose, and lignin in food, and its measurement method is

According to the method described in. The feed for livestock and poultry that is mixed with the dietary leaf iver obtained from any one of the corn husk, wheat bran, and rice bran is not particularly limited, and any form of feed may be used. For example, grains such as corn, milo, barley, and wheat; brans such as rice bran and grains; defatted meal such as soybean meal, flaxseed meal, and safflower meal; processed livestock and fishery products such as fish meal, meat meal, meat and bone meal, and feather meal. and its by-products; agricultural manufacturing by-products such as starch meal, gluten feed, beet pulp, bagasse, and beer lees; plant stems and leaves such as alf-alf ameal; and other suitable feed materials such as minerals and vitamins. Examples include powdered or solid feed obtained by appropriately crushing and mixing feed ingredients, or further processing such as molding. In the present invention, the amount of dietary leaf iver obtained from corn husk, wheat bran, or rice bran to be mixed into feed for livestock and poultry is as follows:
The desirable range is 1 to 15% by weight based on the total feed.
Particularly preferred is a range of 2 to 8% by weight. When the feed for livestock and poultry of the present invention is fed to livestock and poultry, loose stools can be prevented due to the indigestible components of dietary leaf iver, and feed efficiency is thereby increased, resulting in good egg production and breeding performance. There is an effect. Incidentally, even if a large amount of conventional raw materials containing so-called crude fiber is used, the above-mentioned effects cannot be obtained, probably because the nutritional balance of the feed as a whole is impaired. In addition, dietary leaf ivar, whose main components are cellulose, hemicellulose, and lignin, can be used to control increases and decreases in serum cholesterol, obesity, diabetes, etc.
It has been recognized that there is a correlation between preventing appendicitis and colon cancer, and promoting the elimination of toxic substances from food. Therefore, the feed of the present invention in which dietary leaf iver is added and mixed has the above-mentioned physiological activity, and therefore, for example, when fed to egg-laying hens, it is expected to have the effect of producing eggs with reduced cholesterol content. be done. Next, the present invention will be explained in more detail with reference to Examples, but the present invention is not limited to these Examples. In the examples, parts and % are parts by weight and % by weight. Example 1 Dietary leaf eyelid obtained from corn (NDF) was added to the feed for adult chickens having the composition shown in Table 1.
83.5) to obtain feed for adult chickens. The dietary leaf eyelid obtained from the above corn was prepared by the following method. A dispersion of corn fibers separated and produced by wet milling of corn (solid content: 5
%) to pH 7.0, add 0.4% of Bioplase SP-10 (manufactured by Nagase Sangyo Co., Ltd.), and heat at 50°C with stirring.
After being kept overnight, centrifugal dehydration and washing were performed twice. This was made into a dispersion liquid again, adjusted to pH 7, added with amylase T-5 (manufactured by Daiwa Kasei Co., Ltd.), and heated to 90°C.
The mixture was kept for 3 hours while stirring. Similarly, centrifugal dehydration,
It was washed, dried at room temperature, and ground to obtain dietary leaf eyebar (NDF 83.5).

【table】

[Table] Next, the feed obtained in this way (the feed of Example 1) and the composition shown in Table 1 were prepared by replacing 5 parts of dietary leaf iver derived from corn with 5 parts of rice bran (NDF 24.3). A feed mixed with chicken feed (control feed) and a feed mixed with 5 parts of corn fiber instead of 5 parts of dietary leaf iver derived from corn (comparison feed) were each fed to 10 laying hens. The animals were kept for two weeks with free access to feed and water. The egg-laying rate and water content of chicken manure during the rearing are shown in Table 2. In the test plot fed with the feed of Example 1, loose stools were prevented and the egg-laying rate was good.

[Table] Example 2 According to the formulation shown in Table 3, feed materials were crushed and mixed to obtain feed for breeding pigs. In addition, the wheat dietary leaf eyelid in Table 3 is obtained by pulverizing commercially available wheat bran with an atomizer, washing it with water using a 16-mesh sieve, sieving it with water, collecting the residue on the sieve, and drying it. Obtained NDF
46.2 wheat dietary leaf eye bar.

【table】

[Table] Feed thus obtained (feed of Example 2),
When a feed (control feed) in which wheat bran was mixed into the feed for breeding pigs with the composition shown in Table 3 in place of 5 parts of wheat dietary leaf iver was fed to breeding pigs, the number of offspring, number of days of return to estrus, Although there was no difference in feed intake, etc., the weight loss of sows at weaning was approximately 2% lower in this test group than in the control group.
In addition, the moisture content in feces was 75.0% on average in the test plots and 77.0% on average in the control plots, and the breeding performance and condition of feces were good in the plots fed the feed of the present invention.
