JPS619255A - Breeding of monogastric livestock - Google Patents

Abstract

PURPOSE:To breed monogastric livestock such as pig, chicken, etc., suppressing diarrhea and loose passage caused by the administration of highly nutrient feed, etc., by feeding the livestock with feed added with a slight amount of L- threonine. CONSTITUTION:L-threonine is added to a feed in an amount of 0.001-1.0wt%, preferably 0.01-0.5%, and mixed homogeneously. The obtained mixture is administered to a monogastric livestock such as pig, chicken, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a breeding method for suppressing symptoms of diarrhea and loose stools occurring in monogastric livestock.

In recent years, compound feeds for livestock have tended to be high in protein and high in calories in order to accelerate the growth rate of livestock and increase feed efficiency. However, from the viewpoint of the physiology of livestock, such highly nutritious feed imposes an excessive burden on digestion and absorption, resulting in monogastric livestock suffering from diarrhea and other physiological causes. Symptoms of loose stool often occur, which poses a problem in breeding management. In other words, the feed fed to monogastric livestock for the above-mentioned purposes frequently causes symptoms of diarrhea and loose stools, and instead of fulfilling its original purpose, it actually reduces the productivity of livestock breeding, so countermeasures are required. is strongly requested.

The present invention was made in view of the above-mentioned situation in raising monogastric livestock such as pigs and chickens, and is intended to suppress the symptoms of diarrhea and loose stool that frequently occur in monogastric livestock. The object of the present invention is to provide a method for raising such livestock.

The present invention will be explained in detail below.

The characteristics of the present invention are that the L-threonine content is 0.001 to 1.0
The object of the present invention is to suppress the occurrence of symptoms of diarrhea and loose stool in monogastric livestock by feeding the monogastric livestock with feed containing % by weight.

The term "monogastric domestic animal" as used herein means a domestic animal having a stomach with a monocap structure, and typical examples include pigs and chickens.

L-) leonine used in the feed in the present invention is known as an essential amino acid nutritionally for monogastric livestock.
Its nutritional effects on livestock have also been reported [
For example, M.F., Fuller et al.
Nutrition 5ocfety”, Alan
T, Davis etal” J, Nutritio
n 112, 2170 (1980)].

However, there have been no reports yet on the inhibitory effect of L-)leonine on the symptoms of diarrhea and loose stool in monogastric livestock.

In the present invention,
L-) leonine is added to the feed in an amount of 0.001 to 1.0% by weight, preferably 0.01 to 0.5% by weight, and the mixture is uniformly mixed and fed. It is preferable to mix L-) leonine with the above-mentioned feed by applying a conventional mixing method for feed formulation.

According to the present invention, by feeding feed containing an extremely small amount of 1,-threonine as described above, even if a highly nutritious feed as described above is fed, the effects of 1,-threonine can be reduced. It becomes possible to effectively suppress the occurrence of symptoms of diarrhea and loose stools.

In other words, the present invention can solve the problem of suppressing the symptoms of diarrhea and loose stools that frequently occur in monogastric livestock, which has been considered difficult in the past, and is therefore an important problem in the breeding of monogastric livestock. It can be said that the diameter is large.

EXAMPLES The effects of the present invention will be specifically explained below with reference to Examples.

Implementation N1
24 piglets aged 3 to 4 weeks old were divided into four test sections, one of which was used as a control group and fed a compound feed mainly containing skim milk powder and wheat flour, and the other three were fed a compound feed mainly containing skim milk powder and wheat flour. A 15-day breeding test was conducted by feeding these rats with the above-mentioned mixed feed with L-1-leonine added in the amounts shown in Table 1 below.

The results are shown in Table 1.

As shown in Table 1 above, the occurrence of diarrhea and loose stools in all the piglets of the present invention group fed the feed according to the present invention was significantly reduced compared to the piglets of the control group.

Fugamasu 1 24 piglets aged 40 and 41 days old were divided into four test groups, one of which was used as a control group, and fed a compound feed mainly consisting of corn, wheat flour, and soybean meal, and the other These three are considered as the present invention, and L-
) A 35-day breeding test was conducted by feeding leonine in the amounts shown in Table 2. The results are shown in Table 2.

As shown in Table 2 above, the occurrence of diarrhea and loose stool was suppressed in all the piglets of the present invention group fed the feed according to the present invention compared to the piglets of the control group.

Inusekan ↓ 14 piglets aged 60 days were divided into two test sections, the control group was fed a compound feed mainly containing corn, milo and soybean meal, and the compound feed was further supplemented with 0.000 L-1-leonine. A breeding test was conducted in which feed containing 0.02% by weight was fed to each of the test plots of the present invention for 56 days. The results are shown in Table 3.

As seen in the above table, the occurrence of diarrhea and loose stool was suppressed in the piglets of the present invention group fed the feed according to the present invention compared to the control group.

Implementation ■↓ 800 first-born broiler chicks were divided into 4 test plots, one of which was fed a compound feed mainly containing corn, milo, soybean meal, and fishmeal as a control group, and the other three were fed a compound feed containing mainly corn, milo, soybean meal, and fish meal. As a result, they were fed the above-mentioned mixed feed with L-) leonine added in the amounts shown in Table 4,
An 8-week breeding test was conducted. The results are shown in Table 4.

(Note) Broilers are kept free-range, and it is difficult to directly calculate the incidence of diarrhea and loose stools from the properties of feces. Therefore, the amount of water consumed was measured and the amount of water consumed/feed intake was calculated. was used as data for determining fecal properties. That is, since chickens excrete urine and feces together through the cloaca, the amount of water they drink is directly related to the quality of their feces.

On the day the test ended, 10 birds were randomly selected from each test plot, kept in a cage, and one day's worth of excrement and urine excreted into a receiver was collected and its water content was measured.

As shown in Table 4 above, the chickens in the test area fed the feed according to the present invention had better live weight and feed conversion ratio, and had lower water/feed intake than those in the control group. It can be seen that the moisture content of the feces is also low, and the properties of the feces are significantly improved.
