Description

Poultry feed, method for increasing weight of muscular stomach of poultry, and method for raising poultry

The invention is divisional application of patent application with application number 201780045991.7, entitled poultry feed, method for increasing weight of muscular stomach of poultry, and attorney rearing method, which is proposed by 26.7.7.2017.

Technical Field

The present invention relates to a poultry feed, a method for increasing the muscular stomach weight of poultry using the poultry feed, and a method for raising poultry using the poultry feed.

Background

Typical examples of poultry include egg laying chickens (laying hens, laying hens (layers)) for collecting eggs, meat chickens (broilers) for preparing meat, and egg and meat chickens, depending on their use. Wherein, the breeding stage of the laying hens comprises the following steps: a growing period (about 0 to 18 weeks old) during which the chickens grow to a state in which the chickens can lay eggs (egg-taking chickens, adult chickens); and a laying period of about 2 years from the start of laying, until the chicken is raised as a laying chicken, the laying rate is reduced, the utilization value is reduced, and the chicken is treated as a broiler chicken.

The term "more detailed classification" of the growing period of the laying hens includes each period of a young chick period (approximately 0 to 4 weeks old), a middle chick period (approximately 4 to 10 weeks old), and a young chick period (approximately 10 to 18 weeks old).

However, in order to sufficiently exhibit the egg-laying ability of the chickens in the egg-laying period, it is naturally important to appropriately control the feed supplied to the chickens in the egg-laying period, environmental factors, and the like, but this is not sufficient.

That is, although the egg laying ability of chickens is improved as a result of the growth of the ovaries and oviducts of the chickens from the late stage of the breeding to the initial stage of egg laying, the amount of feed (feed intake) of the chickens is stagnated due to physiological stress caused by the growth of the ovaries and oviducts, and there are cases where adverse effects such as a decrease in the initial egg weight or an increase in the period required until the peak of egg laying are reached occur.

In order to prevent such a situation, it is important to improve the feeding ability of the chicken from the late stage of the breeding period to the peak stage of the egg laying and to secure the amount of food required to satisfy the nutrient requirement for the continuous egg laying, and therefore, it is advantageous to grow and increase the digestive tract, particularly the muscular stomach, of the chicken in the breeding period before the egg laying period and to increase the volume thereof in advance.

The muscular stomach is one of digestive organs of poultry represented by chicken, also called as a forestomach, and constitutes the stomach of poultry together with glandular stomach that secretes gastric juice. The feed mixed with gastric acid and digestive ferment in the glandular stomach is fed to the muscular stomach, which is a pouch organ including a thick muscular layer, and is crushed and digested by contraction and relaxation motions of the muscular stomach, and further digested and absorbed in the duodenum or below.

In addition, coarse grains (sand and stone) which are taken by poultry are stored in the muscular stomach, and the feed is crushed and ground along with the contraction and relaxation movement of the muscular stomach, thereby promoting digestion. In the state including coarse grains, the muscular stomach repeats contraction and relaxation movements more actively, so that the muscular stomach increases its weight to grow larger, thereby improving the digestion ability and increasing the feed intake of poultry.

However, in the current industrial breeding environment, only a general formula feed is supplied, and during this period, the poultry cannot accumulate coarse grains in the muscular stomach, and the weight increase in the muscular stomach is insufficient, and it is important to solve the above-mentioned problem.

Growing the muscular stomach to increase the feed intake is important not only for the egg-laying chicken described above but also for broiler chicken, another major use of chicken.

Broiler chicken is a generic term for chickens raised for eating purposes. The term broiler also includes chicken called "native chicken" which is raised over a long period of about 12 to 17 weeks after hatching in order to produce delicious or chewy meat, but generally, a broiler refers to a broiler chicken (broiler chicken) which is raised so as to rapidly grow to a body weight of about 2.5 to 3.5kg within a period of about 6 to 8 weeks after hatching and then is delivered for eating.

In the case of meat chicken, the edible parts relate to a plurality of parts, and not only skeletal muscles such as leg, shoulder, chicken wings, chicken breast, and chicken neck, but also internal organs such as heart, liver, kidney, and stomach (gizzard) can be edible.

The broiler chicken starts to reform in the early stage of raising from hatching to about 3 weeks of age, and the growth rate is increased, and by supplying an appropriate feed in the early stage of raising, the weight of the stomach is increased and the growth is achieved, and the feed consumption in the late stage of raising (after 3 weeks of age) is increased, whereby it is expected that a better physical performance is obtained, and a fat stomach with a higher commercial value is obtained.

Under the circumstances described above, in order to avoid adverse effects of physiological stress from the late stage of incubation to the early stage of egg laying on egg weight or peak egg laying of poultry, such as chicken, and to obtain more meat or internal organs from poultry, it is desired to develop a poultry feed capable of efficiently increasing the weight of the muscular stomach of poultry.

For the purpose of promoting the growth of poultry muscular stomach and improving the raising performance, there is known a poultry feed containing 0.5 to 10 parts by weight of ground corn cob meal (corn-cob meal) per 100 parts by weight of the feed before the corn cob meal is mixed (patent document 1); a feed for poultry prepared from grains and containing 0.1 to 10 parts by weight of hulls of the grains such as rice hulls, buckwheat hulls, and wheat hulls based on 100 parts by weight of the feed before blending (patent document 2).

Further, as a poultry feed for promoting the growth of the muscular stomach of poultry and improving the grower, a poultry feed containing ceramics (ceramics) having a purity of 99% or more and a hardness of at least 70kg, which is alumina (aluminum), is known (patent document 3).

Disclosure of Invention

Problems to be solved by the invention

However, the inventions of patent documents 1 and 2 show the dressing-improving effect, but the muscular stomach-enlarging effect of poultry is not sufficient.

In addition, in the invention of patent document 3, since coarse grains (sand) are replaced with the contents of the muscular stomach, after sintering and coarsely crushing the alumina powder having a purity of 99% or more, it is necessary to add the alumina powder to the feed at an appropriate particle size according to the age of the poultry, and there is a concern about the complexity of the work.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a poultry feed which can efficiently increase the weight of the muscular stomach of poultry in the growth stage and the early stage of feeding, and can increase the feeding ability and the feed intake amount of poultry in the initial stage of laying and the early stage of feeding, a method for increasing the weight of the muscular stomach of poultry, and a method for feeding poultry.

Means for solving the problems

The present inventors have made extensive studies to solve the above problems, and as a result, have found that: when a feed containing a specific cellulosic material is supplied to laying poultry in the growing period or meat poultry in the early stage of rearing, the weight of the muscular stomach can be increased efficiently, and as a result, the feeding ability and the feed intake amount of laying poultry in the initial stage of laying or meat poultry in the later stage of rearing can be increased.

The invention of the present application is characterized by the following aspects.

1. A feed for poultry, wherein 0.1 to 5 parts by mass of a cellulosic raw material is blended per 100 parts by mass of the feed before blending the cellulosic raw material.

2. A feed for poultry comprises cellulosic material selected from buckwheat hulls, rice hulls, oat, sunflower seeds, pine nut hulls, palm kernel hulls, hay blocks (hay cubes), mixed hay pellets (mixed hay pellets), walnut hulls, and jujube kernels.

3. A feed for poultry, wherein a cellulosic material is formulated so as to exhibit an effect of increasing the weight of the muscular stomach of the poultry.

4. A feed for poultry, wherein the particle size of the cellulosic material is 1 mm-6 mm.

5. A method for increasing the weight of the muscular stomach of poultry, which comprises feeding said poultry with a feed.

6. A method of raising poultry by feeding said poultry with a feed.

ADVANTAGEOUS EFFECTS OF INVENTION

According to the present invention, by supplying a feed containing a specific cellulosic material to laying poultry in a growing period or meat poultry in a previous stage of rearing, the weight of the muscular stomach can be increased efficiently, and as a result, the feeding ability and the feed intake amount of laying poultry in an initial stage of laying or meat poultry can be increased.

Detailed Description

The cellulosic material blended in the feed of the present invention may be any one selected from buckwheat hulls, rice hulls, oats, sunflower seeds, pine nut hulls, palm kernel hulls, hay blocks, mixed hay pellets, walnut hulls, and date kernels. These cellulosic materials may be used in combination of two or more kinds to prepare a feed.

Rice hull: the outer husk remaining after removing rice from the rice.

Oat: seeds of Avena sativa L.of the genus Avena of the family Poaceae.

Sunflower seeds: seeds of sunflower of an annual plant of the Compositae family.

Pine nut shells: removing the residual shell from the seed of the plant of Pinus of Pinaceae after removing the endosperm part.

Palm kernel shell: the outer skin of seed of oil palm of Cocoiaceae.

Dried grass blocks: drying forage grass such as alfalfa hay as a feed for dairy cattle, cutting the forage grass, and compressing and shaping the forage grass into a rectangular parallelepiped shape having a side of 2cm to 5 cm.

Walnut shells: the seed (kernel) of a walnut tree belonging to the genus Juglans of the family Juglandaceae is removed from the inner seed to form an outer skin.

And (3) jujube kernel: seeds of small arbor of Ziziphus of Rhamnaceae. The jujube kernel can be used by pulverizing the jujube kernel and separating only the shell, or the whole pulverized product including the shell can be used as it is.

The blending ratio of the cellulosic material is preferably 0.1 to 5 parts by mass, more preferably 0.3 to 3 parts by mass, and still more preferably 0.5 to 2 parts by mass, based on 100 parts by mass of the feed before blending the cellulosic material.

When the cellulosic material is described, the amount of the buckwheat hulls is preferably 1 to 5 parts by mass, more preferably 2 to 3 parts by mass, per 100 parts by mass of the feed before the cellulosic material is blended. The rice husk is preferably 1 to 5 parts by mass, more preferably 2 to 3 parts by mass. The amount of the palm kernel shell is preferably 0.1 to 5 parts by mass, and more preferably 0.5 to 3 parts by mass. The walnut shell is preferably 0.1 to 5 parts by mass, and more preferably 0.5 to 3 parts by mass.

If the blending ratio of the cellulosic raw materials is less than the lower limit of the blending ratio of each cellulosic raw material, the effect of increasing the weight of the muscular stomach of the poultry is difficult to obtain, and if it is greater than the upper limit of the blending ratio of each cellulosic raw material, the feeding ability of the poultry is lowered, or it is difficult to satisfy the required nutrient intake of the poultry in the growing period or the early stage.

The particle size of the fibrous raw material is preferably about 1mm to 6mm, more preferably about 1mm to 4mm, and still more preferably about 1mm to 3 mm. If the particle size is less than the above range, the fibrous material ingested by the chicken is not retained in the muscular stomach but is fed to the small intestine or less, and the effect of promoting the increase in the muscular stomach weight by the contraction and relaxation movement of the muscular stomach is difficult to obtain, and if the particle size is more than 4mm (6 mm in the case of buckwheat hulls), the fibrous material may not be uniformly mixed in the mixed feed, and besides, ingestion of the poultry may be physically difficult, and thus the poultry may be insufficient.

The feed of the present invention can be widely supplied to poultry such as chickens, ducks and the like, but chickens are preferred. The kind of chicken to which the feed of the present invention is supplied is not particularly limited.

Examples of egg-laying chickens include Julia chicken (Julia), Maria chicken (Maria), Sonia chicken (Sonia), Boris Brown chicken (Boris Brown), White Leghorn chicken (White-Leghorn), New Hamburgh chicken (New Hampshire), and Australian black chicken (Australorp).

The grain size of the palm kernel shell, the date kernel and the walnut shell is 1.0 mm-2.47 mm.

(Note 1) CP, loud protein, crude protein

The protein in the feed is not directly quantified, but the amount of nitrogen (nitrogen concentration wt%) is measured and multiplied by a coefficient determined according to the type of the raw material, and the product is converted into the protein mass to be quantified, and is referred to as "crude protein". The quantitative determination of the nitrogen amount was carried out by a combustion method as a machine analysis method.

(Note 2) ME, metabolic energy

The energy of feces, urine and gas is subtracted from the total energy of the feed, and this is called metabolic energy. For poultry, the amount of energy lost by gas is negligible, so ME is the total energy minus the energy of feces and urine. The total energy amount of each raw material to be blended, the metabolic rate of the raw material, and the blending ratio of the raw material are determined, and the metabolic energy of all the raw materials are summed up to determine the total metabolic energy.

For each test chicken, the weight of the muscular stomach (g/chicken), the weight ratio (%) of the muscular stomach, the weight gain (g/chicken), and the feed requirement rate were determined.

The test results are shown in [ attached table 6] and [ attached table 7], and as shown below, it was confirmed that the chickens in the test area were superior to the control area in terms of the weight of the muscular stomach, the development performance, and the like.

The weight gain of the muscle stomach was confirmed by supplying palm kernel shells, jujube kernels and walnut shells to the middle chicks and chicks of laying hens (Julia seeds) at the age of 38-119 days.

In addition, the palm kernel shell, the jujube kernel and the walnut shell are supplied to the middle-sized young chicken and the large-sized young chicken, so that the development performance, namely the body building and the feed requirement rate in the breeding period are improved.

Further, it was confirmed that the effects of increasing the weight of the muscular stomach and improving the development performance were exhibited by adding 0.5 mass% of each of the palm kernel shell, the date seed shell and the walnut shell.

From the above test results, the effectiveness of the feed of the present invention was confirmed.
