Abstract

PURPOSE:To obtain a feed reducing an amount of ammonia evolved in cattle, raised fishes, etc., in barns, decreasing accidents caused by pecking of tail in chicken raising, improving absorption ratio of iron, by blending a feed with a ferrous salt containing an organic acid having reducing action. CONSTITUTION:An organic acid (e.g. ascorbic acid, erysorbic acid, nordihydroguaiaretic acid, gallic acid, etc.) having reducing action is added and dissolved in an aqueous solution of ferrous salt such as ferrous sulfate, etc., and the solution is concentrated, crystallized or powdered. A feed is blended with preferably 0.001-0.03% of the prepared substance.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application J] The present invention relates to feed for livestock, poultry, farmed fish, etc., which has improved iron absorption rate.

[Prior art and its problems] In recent years, with the expansion and intensification of livestock farming, there has been increasing interest in the environmental impact on livestock animals.For example, ammonia generated from excreted manure is Ammonia is considered to be an important substance that has a negative impact on livestock animals, and controlling ammonia fog in livestock housing is an important point in livestock management. It is generated as a protein breakdown product in the intestinal tract, and has a negative impact on the productivity and health of livestock animals.

Currently, there are many various additives on the market for the purpose of improving the livestock barn environment and intestinal environment, but all of them are expensive.
No inexpensive and effective additives have been developed.

[Means for Solving the Problems] As a result of intensive studies to solve these problems, the inventors have developed 21i! This objective could be achieved by stabilizing the iron in [i] with an organic acid having a reducing effect and adding it to the feed.

In other words, the present invention has a reduction effect on RIS! fl in livestock or poultry feed containing divalent iron salts containing
Qtl.

Although IIM has a reducing effect, it goes without saying that it is not a problem as a feed additive. Examples of organic acids include ascorbic acid, erythorbic acid, nordihydroguaiaretic acid, and gallic acid.

This organic acid may be in the form of a divalent iron salt or in the form of an adduct. In the case of a salt, it may be a double salt with other t1 acid or no t1 acid.

Examples of other R acids include citric acid, tartaric acid, and succinic acid; examples of inorganic acids include hydrochloric acid, sulfuric acid, phosphoric acid, and carbonic acid. Such a divalent iron salt containing an organic acid having a reducing action can be used alone or in combination of two or more kinds.

In the case of double salts, such iron salts are disclosed in, for example, JP-A-58-
According to the method described in Publication No. 156539, etc., an organic acid having a reducing action is added and dissolved in an aqueous solution of 21iffi iron salt of the other organic acid or inorganic acid, and if necessary, PLL is adjusted, concentrated, and crystallized. Alternatively, it may be powdered. When making a salt containing only an organic acid with a reducing action and divalent iron, an appropriate method may be selected from known methods for producing salts, but a simple method is to use an ion exchange resin. be. This method uses, for example, strong acid 21
It has a reducing effect on aqueous solutions of iron salts of 1IIIi! 5! I
In this method, after adding FI, a predetermined amount of free basic resin is added to adsorb and remove the strong acid.

The divalent iron salt containing an endoacid having a reducing effect may be added to the feed in the form of a powder or an aqueous solution. The amount added is usually about 0.001 to 0.1% in powder form, preferably about 0.001 to 0.03%. As for the blending method, it is sufficient that the components can be mixed uniformly, and in the case of powder, they may be mixed together with other components or by adding them sequentially. In the case of an aqueous solution, it may be uniformly poured or sprayed with appropriate mixing during or after blending. It may be uniformly mixed in advance with any of the components before blending.

Other feed ingredients may be the same as known feeds for livestock, poultry, or farmed fish, and the feeding method may be the same as conventional feeds.

The type of livestock, poultry, and farmed fish does not matter, but for example, pigs,
The feed of the present invention is effective for cattle, chickens, eels, etc.

[Function] By incorporating an organic acid having a reducing action into the divalent iron salt, the iron ions contained therein are kept divalent for a long time.

[Example 1 Example 1 Commercially available Buler feed ([CI Proace SJ,
A powder obtained by adding ferrous sulfate and mono-ascorbic acid to "C.I. Pro Ace GJ, Itochu Feed■)" and drying it ("Anico J, Minato Sangyo Kan, Fe 24.6%
(containing) were added and mixed to be 0.03% and 0.10%.

The above 2PF feed and a control feed to which the ferrous salt-containing powder was not added were tested for their effects on the growth of broilers.

Each test group consisted of 30 male birds and 130 FF birds, each aged 0 days, and was reared in the above-mentioned [C.I. Pro Ace S] until 21 days old, where 1N M
[The birds were rearranged into 4 groups, each group consisting of 45 birds, and reared in "C.I. Pro Ace G" until they were 59 days old.

The table below shows the results of measuring weight gain, feed conversion rate, amount of ammonia generated in stored feces, etc. for each test group.

The above results are the average values for males and females from 0 to 59 days old (the amount of ammonia produced is also displayed separately for males and females). The ammonia generation layer was measured after collecting feces at the age of 21 days, placing it in a wide mouth bottle, and storing it in the seedling for 5 days.

The test results are shown below.

Comparative body weight measurement of a pig farm housing 700 pigs.Measurements between feed intakes were not carried out.Example 6 The same first grade as that used in Example 1 was used for commercially available laying hens feed ("C.I. Layer 11M" Itochu Feed ■). A breeding test was conducted on laying hens with the addition of 0.05% iron salt-containing powder.

For laying hens, both the ferrous salt-containing powder added group and the control 8Y were 54.
Using feathers, a breeding test was conducted for a period of 156 days to 181 days. In addition, during the test, conditions were added that made it more likely that butt pecks would occur.

The breeding results are shown below.

Example 7 0.03% of the same ferrous salt-containing powder used in Example 1 was added to commercially available laying hens feed ("C.I.Layer 11M" Itochu Feed ■), and 10,000 laying hens were divided into two groups. A field rearing test was conducted separately, and the number of deaths caused by butt peck was compared between the animals with and without the addition. The results are shown in the table below.

Example 8 A breeding test of eels was conducted by adding 0.01% of the same ferrous salt-containing powder used in Example 1 to a commercially available feed (Eel Mash J). A total of 420 SWI fish were raised in each group for both the addition group and the control group for 4 periods with the 26th day as the first period.
After completing the 26 days of the period, replace the tank and replace the tank.
They were bred for 6 days, then the middle-sized ones were extracted and bred for the third period of 26 tons, and then the tanks were replaced and the fourth period was raised.
The animals were kept for 26 days during the period. The breeding results are shown in the table below.

Fruit/1115'! 9 The same ferrous salt-containing n powder as used in Example 1 was added to commercially available rearing feed ("C.I. Calf" Itochu Fei ■1) at 0.01%.
In addition, a cattle breeding test was conducted.

Five calves were used in both cities for the joint test cows. The amount of waste generated has decreased, and the problem of being in the back of the livestock barn has been greatly improved. In addition, the number of days off, feed P# requirement rate, survival rate, etc. were improved. In layer hens, egg production rate and egg weight have also been improved, including layer hens and broilers! In chickens, accidents caused by butt pecks were also reduced.

The occurrence of blind spots due to butt pecking is a problem throughout the chick, rearing, and adult stages, but it occurs particularly frequently from the start of egg laying to the peak of egg laying, causing great damage to poultry farmers. Conventionally,
The most effective way to deal with this problem was to cut the beak short during the chick-rearing period, but the damage caused by butt pecking was still significant.

This problem was also improved by the feed of the present invention.
