Description
本発明は、養鶏用飼料添加剤およびけい酸カルシウム含有養鶏用飼料に関する。 The present invention relates to a poultry feed additive and a calcium silicate-containing poultry feed.
鶏卵の卵殻強度は、産卵する鶏の加齢に伴って低下する。また、鶏卵の卵殻強度は、夏季の暑熱によるストレス等によっても低下する。卵殻強度が低下した場合、卵殻が割れたり（破卵）、卵殻にひびが入る（ヒビ卵）等の問題が起こりやすくなる。
このため、鶏卵の卵殻強度を向上させることができる種々の飼料添加剤が提案されている。
鶏の産卵後半の卵殻質を改善し、卵殻強度を向上させることができる飼料添加剤として、例えば、特許文献１には、ラクトビオン酸又はラクトビオン酸の塩を含む産卵鶏用の飼料添加剤が記載されている。
また、特許文献２には、海洋から採取したコーラルサンドからなる卵殻質改善用添加剤が記載されている。
一方、産卵する鶏の加齢に伴って産卵率が小さくなり、飼料要求率（卵の単位質量あたりの餌の量）が大きくなるため、飼料のコストが増加するという問題もある。これに対して、リン酸カルシウム等を飼料に混ぜることで産卵率を大きくし、飼料要求率を小さくする方法も知られているが、その効果は不十分である。Egg shell strength decreases with age of laying chickens. In addition, the egg shell strength of chicken eggs also decreases due to stress caused by the heat of summer. When the strength of the eggshell is reduced, problems such as cracking of the eggshell (broken egg) and cracking of the eggshell (cracked egg) are likely to occur.
Therefore, various feed additives that can improve the egg shell strength of chicken eggs have been proposed.
As a feed additive capable of improving the eggshell quality and the eggshell strength in the latter half of spawning of chickens, for example, Patent Document 1 describes a feed additive for spawning chickens containing lactobionic acid or a salt of lactobionic acid. Has been done.
Further, Patent Document 2 describes an additive for improving eggshell quality, which is made of coral sand collected from the ocean.
On the other hand, as the laying chickens age, the egg-laying rate decreases and the feed conversion ratio (the amount of feed per unit mass of eggs) increases, so that there is also a problem that the cost of feed increases. On the other hand, there is also known a method of increasing the egg-laying rate and reducing the feed conversion ratio by mixing calcium phosphate or the like with the feed, but the effect is insufficient.
本発明の目的は、産卵鶏の卵の卵殻強度（例えば、卵殻破壊強度）を大きくして、破卵やヒビ卵の発生を抑制することができ、産卵率を大きくし、かつ、飼料要求率を小さくすることができる、養鶏用飼料添加剤および該添加剤を含むけい酸カルシウム含有養鶏用飼料を提供することである。 An object of the present invention is to increase the eggshell strength (for example, eggshell breaking strength) of a poultry laying chicken to suppress the occurrence of egg breakage and cracked eggs, increase the egg laying rate, and feed conversion ratio. Is to provide a poultry feed additive and a calcium silicate-containing poultry feed containing the additive, which can be reduced in size.
本発明者は、上記課題を解決するために鋭意検討した結果、けい酸カルシウム含有材料を含み、可溶性けい酸の含有率が１０質量％以上であり、かつ、可溶性石灰の含有率が１０質量％以上である養鶏用飼料添加剤によれば上記目的を達成できることを見出し、本発明を完成した。
すなわち、本発明は、以下の［１］～［３］を提供するものである。
［１］ けい酸カルシウム含有材料を含み、可溶性けい酸の含有率が１０質量％以上であり、かつ、可溶性石灰の含有率が１０質量％以上であることを特徴とする養鶏用飼料添加剤。
［２］ 前記［１］に記載の養鶏用飼料添加剤、および、養鶏用飼料を含むけい酸カルシウム含有養鶏用飼料であって、可溶性けい酸の含有率が０．０３～１０質量％であり、かつ、可溶性石灰の含有率が１．０～２０質量％であるけい酸カルシウム含有養鶏用飼料。
［３］ 上記養鶏用飼料添加剤の量が、上記養鶏用飼料１００質量部に対して０．１～１０質量部である、前記［２］に記載のけい酸カルシウム含有養鶏用飼料。As a result of diligent studies to solve the above problems, the present inventor contains a calcium silicate-containing material, the content of soluble silicic acid is 10% by mass or more, and the content of soluble lime is 10% by mass. The present invention has been completed by finding that the above-mentioned object can be achieved by the above-mentioned feed additive for chicken raising.
That is, the present invention provides the following [1] to [3].
[1] A poultry feed additive containing a calcium silicate-containing material, having a soluble silicic acid content of 10% by mass or more and a soluble lime content of 10% by mass or more.
[2] The poultry feed additive according to the above [1] and the calcium silicate-containing poultry feed containing the poultry feed, wherein the content of soluble silicic acid is 0.03 to 10% by mass. A poultry feed containing calcium silicate having a soluble lime content of 1.0 to 20% by mass.
[3] The calcium silicate-containing poultry feed according to the above [2], wherein the amount of the poultry feed additive is 0.1 to 10 parts by mass with respect to 100 parts by mass of the poultry feed.
本発明の養鶏用飼料添加剤および該添加剤を含むけい酸カルシウム含有養鶏用飼料によれば、産卵鶏の卵の卵殻強度（例えば、卵殻破壊強度）を大きくして、破卵やヒビ卵の発生を抑制することができる。特に、生後７２週程度の加齢の進んだ産卵鶏であっても、卵の卵殻強度を大きくすることができ、かつ、産卵率を向上することができる。また、養鶏における産卵鶏の更新（産卵鶏を若い鶏に入れ替えること）期間を延長することができる。
また、飼料要求率（単位卵生産量あたりの給餌量；卵の単位質量（例えば、１ｋｇ）あたりの餌の量）が小さくなるため、大幅に飼料のコストを下げることができる。According to the poultry feed additive of the present invention and the calcium silicate-containing poultry feed containing the additive, the eggshell strength (for example, eggshell breaking strength) of the eggs of the spawning chicken is increased to increase the eggshell strength and cracked eggs. The occurrence can be suppressed. In particular, even in an aged laying hen about 72 weeks old, the egg shell strength can be increased and the egg laying rate can be improved. In addition, the renewal period of spawning chickens (replacement of spawning chickens with young chickens) in poultry farming can be extended.
In addition, since the feed conversion ratio (feeding amount per unit egg production amount; feed amount per unit mass of eggs (for example, 1 kg)) becomes small, the cost of feed can be significantly reduced.

To 100 parts by mass of poultry feed (manufactured by Kanematsu Agritech Co., Ltd., trade name "Matsu-go for adult chickens"), add 0.2 parts by mass of material 1 and mix them to make a mixed feed (calcium acid). Calcium-containing poultry feed) was obtained. The content of soluble silicic acid and soluble lime in the mixed feed was measured in the same manner as the soluble silicic acid and soluble lime of Materials 1-3.
In addition, the obtained mixed feed was fed to 54 spawning chickens (Lohmann Brown breed) 72 weeks old by free feeding for 35 days. The average value of 54 eggs was calculated for the mass and shell breaking strength of the eggs laid by 35 days after the start of feeding. In addition, the spawning rate (number of spawning / number of spawning chickens x 100%) for each day was calculated, and the average value was calculated (indicated as "spawning rate" in Table 2). The mass of the egg was measured using the trade name "Egg Multitester EMT-5200" manufactured by Robotation. The eggshell breaking strength was measured using the trade name "Eggshell Force Gauge" manufactured by Robotation. In addition, the feed intake was measured weekly, and from the obtained values, the feed conversion ratio (feed amount (kg) / unit mass of chicken eggs (1 kg)), which is the feed amount (kg) required for the production of 1 kg of chicken eggs. ) Was calculated.

結果を表２に示す。[Examples 2 to 3, Comparative Examples 1 to 3]
54 laying hens 72 weeks old were fed for 35 days in the same manner as in Example 1 except that the materials of the types and amounts shown in Table 2 were added to 100 parts by mass of the poultry feed and mixed. The contents of soluble silicic acid and soluble lime in the mixed feed, the mass of the laid eggs, and the like were measured in the same manner as in Example 1.
[Comparative Example 4]
54 laying hens 72 weeks old were fed for 35 days in the same manner as in Example 1 except that no material was added. The contents of soluble silicic acid and soluble lime in the mixed feed, the mass of the laid eggs, and the like were measured in the same manner as in Example 1.
The results are shown in Table 2.
表２から、本発明の養鶏用飼料添加剤である資材１を、０．２質量部以上となる量で混合してなる養鶏用飼料を用いた場合（実施例１～３）における卵殻破壊強度（３６．５～３７．３Ｎ）は、比較例１～４における卵殻破壊強度（３５．４～３５．８Ｎ）よりも大きいことがわかる。また、本発明の養鶏用飼料添加剤である資材１を、０．２質量部以上となる量で混合してなる養鶏用飼料を用いた場合（実施例１～３）における産卵率（６２．２～６４．５％）は、比較例１～４における産卵率（５９．０～６０．１％）よりも大きいことがわかる。
さらに、本発明の養鶏用飼料添加剤である資材１を、０．２質量部以上となる量で混合してなる養鶏用飼料を用いた場合（実施例１～３）における飼料要求率（１．３９～１．５４）が、比較例１～４における飼料要求率（１．８５～１．９４）よりも小さいことから、本発明によれば、卵の平均質量を維持し、卵殻破壊強度を向上させているにもかかわらず、産卵率を大きくし、かつ、飼料要求率を小さくすることができることがわかる。From Table 2, the eggshell breaking strength in the case of using the poultry feed obtained by mixing the material 1 which is the feed additive for poultry of the present invention in an amount of 0.2 parts by mass or more (Examples 1 to 3). It can be seen that (36.5 to 37.3N) is larger than the eggshell breaking strength (35.4 to 35.8N) in Comparative Examples 1 to 4. Further, the egg-laying rate (62.) in the case of using the poultry feed obtained by mixing the material 1 which is the feed additive for poultry of the present invention in an amount of 0.2 parts by mass or more (Examples 1 to 3). It can be seen that 2 to 64.5%) is larger than the egg production rate (59.0 to 60.1%) in Comparative Examples 1 to 4.
Further, the feed conversion ratio (1) in the case of using the poultry feed obtained by mixing the material 1 which is the feed additive for poultry of the present invention in an amount of 0.2 parts by mass or more (Examples 1 to 3). Since .39 to 1.54) is smaller than the feed conversion ratio (1.85 to 1.94) in Comparative Examples 1 to 4, according to the present invention, the average mass of eggs is maintained and the eggshell breaking strength is maintained. It can be seen that the egg-laying rate can be increased and the feed conversion ratio can be reduced, despite the improvement in the feed conversion ratio.
