Description

  The present invention relates to a feed for livestock, and in particular, it is possible to improve the production efficiency by improving the livestock weight gain, the feed demand rate (the weight of feed required to increase body weight by 1 kg) and the health condition. This is related to a raw material for feed.

  Currently, livestock farmers use calcium phosphate, especially dicalcium phosphate, to promote livestock growth, but production efficiency is not satisfactory. For example, regarding pig farming, according to the summary of survey results for pig farmers (Pork Disease Bulletin No. 14, 2002, published by the Pig Disease Research Association), the production cost of pork was “increased” and “changed” compared to the previous year. The answer “No” is 86%. In addition, the future management outlook is “no change”, and the management scale is “maintained”, and in order to increase profit without changing the breeding density at the current scale, it is an urgent need to increase production efficiency. is there. In order to improve the production efficiency, it is important to reduce the mortality rate, reduce the feed requirement rate, shorten the shipping date, and improve the quality rate.

  The mortality rate of suckling pigs is 5 to 10%, and the mortality rate after weaning until shipping is also 5 to 10%. The main causes are digestive diseases such as diarrhea and respiratory diseases such as pneumonia. In order to reduce the mortality rate, it is necessary to administer and disinfect vaccines, antibiotics, etc., and these hygiene costs are one of the factors that increase production costs. In addition, the breeding period until the shipment of beef pigs takes an average of 193 days, and the fluctuation range of the pig price and feed price is also large, and the management of livestock farmers is very harsh due to unstable breeding costs.

  Examples of calcium sources that are recognized as feed materials for improving bone growth of domestic animals such as pigs, chickens, and cattle include calcium carbonate, monocalcium phosphate, dicalcium phosphate, and tricalcium phosphate. These are all derived from minerals and have problems in the presence of impurities such as fluorine and bioavailability.

  Regarding livestock feed for improving production efficiency, Patent Document 1 relating to feed containing manganese, patetonic acid and moulted soybean meal has been disclosed. This feed is particularly useful as a feed for chickens such as broilers, which strengthens the skeleton and joints of livestock, enhances immunity and significantly promotes growth, and shows a significant improvement in the chick raising rate and feed demand rate. It is reported. Similarly, a chicken feed containing lactose (see Patent Document 2), a chicken feed containing galactooligosaccharide (see Patent Document 3), a lactic acid bacterium, a lactic acid bacteria crushed product, a lactic acid bacteria culture, and a feed containing a lactic acid bacteria culture residue A composition (see Patent Document 4), and a method for improving the constitution of an edible cow that feeds a high protein-containing feed consisting of fish meal, cottonseed, beer lees, dry yeast, and heated soybeans and a fatty acid calcium salt are also proposed. (See Patent Document 5).

  On the other hand, for foods, inorganic calcium carbonate, organic calcium lactate, calcium gluconate, calcined calcium derived from eggshells and shells, etc. are used as calcium reinforcing agents for bone strengthening.

[Process for producing feedstock containing hydroxyapatite from chicken manure combustion ash]
FIG. 1 shows a method for preparing a hydroxyapatite-containing feed material from chicken manure combustion ash according to Japanese Patent No. 4491612. First, 430.3 kg of water and 69.7 kg of 70% sulfuric acid were mixed, and 100 kg of chicken manure combustion ash was added and dissolved to perform solid-liquid separation. Next, 12 kg of calcium chloride was added to the filtrate and stirred, followed by solid-liquid separation again, and then 30 kg of slaked lime was added to the filtrate and stirred to perform solid-liquid separation. As a result, 136 kg (water content 60%) of a hydroxyapatite-containing feed material in a wet state was obtained. The obtained hydroxyapatite-containing feed material was blown and dried with warm air for about 12 hours to obtain 58 kg (water content 3%) of a dried hydroxyapatite-containing feed material. The obtained dried product of the hydroxyapatite-containing feed material was pulverized with a pulverizer (Masuko Sangyo Co., Ltd .; Mass Colloider) and then sieved with a 30-mesh sieve to obtain a pulverized product of the hydroxyapatite-containing feed material.

  The inorganic component composition of the pulverized product of the hydroxyapatite-containing feed raw material by phosphor X-ray (device: energy dispersive X-ray fluorescence analyzer EDX-800HS manufactured by Shimadzu Corporation) is phosphorus: 13.3%, calcium: 55. At 6%, the pH was 11 (10% aqueous suspension). As a result of structural analysis by an X-ray diffraction apparatus (Rigaku Corporation; RINT2500) (FIG. 4), most of the feed material of the present invention was hydroxyapatite which is a kind of calcium phosphate.

The feeding test of the hydroxyapatite-containing feed material obtained by the above process was conducted. Here, when designing the basic feed used in the test, the phosphorus and calcium of the hydroxyapatite-containing feed raw material were measured according to the feed analysis standard. As a result, phosphorus: 8.9% (absorptiometry), calcium: 26.5 % (Ammonium oxalate method). Table 1 shows the proportions of basic feeds designed based on these analysis results. Dibasic calcium phosphate was used for the feed of the preliminary breeding (acclimation period) and the control group of this test, and the hydroxyapatite-containing feed material of the present invention was used for the test group.
1. Test method (1) Basic feed Preliminary breeding (acclimation period): artificial milk A containing dicalcium phosphate
Main test (control group): artificial milk B containing dicalcium phosphate
Main test (test section): artificial milk C containing hydroxyapatite-containing feed ingredients

(2) Breeding period Preliminary breeding: August 29 to September 4, 2012 (use of artificial milk A)
This test: September 5 to October 3, 2012 (control zone: artificial milk B, test zone: artificial milk C used)
(3) Test pigs Use 12 weaned land race piglets (4 weeks old) (castrated, 6 females each). After pre-breeding for 1 week, this test was divided into 2 groups (3 castrates and 3 females each).
(4) Survey item 1) Body weight and weight gain The body weight was measured at intervals of one week from the start of the test, and the weight gain was calculated.
2) Feed intake and feed request rate Feed intake was measured for each group at weekly intervals from the start of the test, and feed intake and feed request rate per head were calculated.
3) Health status Daily health status was observed and recorded twice a day in the morning and evening at an almost constant time. In addition, about the onset situation of diarrhea, it classified visually by 4 steps, normal stool, soft stool, mud stool, and watery stool.

2. Test results (1) Body weight and weight gain Comparing the control group and the test group, the pigs in the test group tended to gain more quickly. In addition, these average values gradually began to differ from the point when three weeks passed from the start of breeding. Table 2 shows the individual body weight and body weight gain, Table 3 shows the average body weight and average body weight gain of each section, and FIG.

(2) Feed intake and feed demand rate Although there was no difference until the second week of this breeding, the difference gradually began to widen from the third week and the fourth week as well as the change in body weight. Moreover, about the feed request | requirement rate, as shown in Table 4, the test group showed the tendency to become lower than a control group.

(3) Health condition There were more diarrheal piglets in the control group than in the test group, and there were chronic diarrhea individuals in the control group. Table 5 shows the observation results of the health condition. In addition, the pigs in the test area were so energetic that they approached each other as they approached each other and shook between pigs. On the other hand, the control group was not very interested because it was not interested in people.

[Discussion]
The safety of the feedstock containing hydroxyapatite was confirmed in this test. In addition, it was a test with nutritional ingredients, but the growth of the pigs in the test group was good, the weight gain was 24%, the feed intake increased by 11%, and the feed requirement rate was Reduced to 90%. Furthermore, since the pigs in the test group were very energetic compared to the control group, it can be inferred that the hydroxyapatite-containing feed material has some functionality to promote growth and improve health.
