Description

[Detailed description of the invention]

0001

[Industrial Field of Application] This invention provides a breeding method using deaerated water to promote the growth of livestock and poultry.

0002

BACKGROUND OF THE INVENTION In recent years, livestock and poultry have been raised in large numbers and in large numbers for meat, egg collection, etc., and it has become important to reduce the cost of raising livestock including feed. To achieve this, it is necessary to increase feed efficiency, and practical methods include improving breeds through cross-breeding and improving feed ingredients by adding various nutrients (vitamins, hormones). There is.

0003

[Problems to be Solved by the Invention] However, the above-mentioned breed improvement method has the problem that it is difficult to apply it to all of the numerous animal species, and it takes a long time to obtain results. Furthermore, improvements in feed ingredients have the disadvantage that the added nutrients are expensive, and the cost of feed increases due to their preparation and management.

0004

[Means for Solving the Problems] The inventors raised livestock and poultry in the morning and evening while feeding and watering them, observed their growth status, and conducted several experiments. In order to solve the problem, we focused on administering degassed water instead of regular water (tap water, etc.) as drinking water, and arrived at this invention.

[0005] In the present invention, degassed water refers to water obtained by removing dissolved gas components from raw water by using a membrane type degassing module or the like.

[0006]

[Embodiments] Examples of the present invention will be described below. A　Implementation conditions

1. Commercially available solid feed (MF manufactured by Oriental Yeast Co., Ltd.) was fed to Wistar rats (male) weighing approximately 60 grams.
After 7 days of acclimatization, the experiment began.

2. The animals were divided into 3 groups of 15 animals each according to body weight, and each group was given the following drinking water. Group 1: tap water degassed to 0.5 mg O2/liter Group 2: tap water degassed to 2.0 mg O2/liter Group 3: regular tap water

[0009] Here, the degassed tap water to be given as drinking water to the first and second groups is tap water from which dissolved gases have been removed. However, it may be obtained by a heating method or a reduced pressure method. In addition, in such deaerated water, measuring the amount of remaining dissolved gas for each gas would be complicated, so it is necessary to measure the amount of dissolved oxygen that can be easily measured using a commercially available dissolved oxygen meter. It is based on quantity.

3. The animals are fed for 5 weeks using the purified feed shown in Table 1 as experimental feed.

4. After measuring feed intake every morning, uneaten food is discarded and replaced with fresh feed.

5. During the experiment period, 9:00 a.m. every morning and 7:00 a.m. every evening.
: Measure the temperature and amount of dissolved oxygen of drinking water (degassed water, tap water) at 00:00.

6. Rats are weighed every morning.

[Table 1]

B. Implementation results

1. The drinking water temperature during the experiment was 21 degrees Celsius.
It was ~26 degrees. In addition, the amount of dissolved oxygen is 0 in degassed water.
．． The concentrations were 3 to 0.7 mg/liter, 2.0 to 3.0 mg/liter, and 7.0 to 8.5 mg/liter in tap water.

2. Regarding the changes in the body weight of the rats during the experimental period, no significant differences were found among the three groups, as shown in Figure 1.

3. As shown in FIG. 2, there was a significant difference in the feed efficiency of the rats during the experimental period between the first group and the second and third groups. In other words, the feed efficiency in the rats of the first group was higher than that of the other two groups in the first to fourth weeks of the experimental period, and the difference was particularly significant in the rats in the growing stage. The feed efficiency here is (weight gain per week)/(feed intake per week).

4. The total feed intake in each group during the test period was 1st group: 575.9g, 2nd group: 638.1g, 3rd group: 639.4g. This resulted in a feed savings of 10%. In particular, during the growth period (first week to fourth week), the amount of feed is saved by about 1.50%.

5. The above results confirm that feed efficiency can be increased by providing deaerated water as drinking water.

6. The reason for this is that the excellent air displacement power of deaerated water promotes the formation of hydrates in feed ingredients, increases the digestibility of the feed by enzymes, and as a result improves the absorption efficiency of nutrients. In other words, in this example, there was no restriction on feed intake and the rats were allowed to eat freely, so the increase in blood sugar levels due to feed intake caused the rats to feel full and not over-ingest, resulting in less food intake. It is presumed that this is because the amount of feed made them feel full.

7. Based on the above results, by giving deaerated water instead of ordinary tap water as drinking water, it is possible to reduce the amount of feed administered while maintaining the same growth rate. Furthermore,
When various nutritional supplements (vitamins, hormones) are added to the administered feed, the absorption efficiency is improved, so the amount added to achieve the same effect can be reduced.

The above-mentioned effects of the present invention can be applied to livestock and poultry in addition to rats. It is particularly effective when applied to animals in growth stages or sexual states that require nutritional support, such as egg laying, pregnancy, childbirth, and lactation.

[0023]

Effects of the Invention As explained above, according to the method for improving animal growth and feed efficiency according to the present invention, absorption of nutrients in feed is improved by giving deaerated water as drinking water instead of regular water. Due to the increased efficiency, less feed is required to obtain the same amount of growth, and when using highly nutritious feed, the absorption efficiency is improved as mentioned above, which reduces the amount of feed during the growth period. It also has the effect of shortening the length and increasing final weight. Furthermore, when adding nutrients or growth promoters to the feed, since the absorption efficiency is high, the amount of addition needed to obtain the same effect is small, and breeding costs can be reduced.

On the other hand, even when a feed with low nutrient absorption efficiency is administered, the same growth period and final body weight as when using a normal feed can be obtained.
