Description
Technical Field
The invention relates to the field of feed additives, in particular to a compound feed additive for preventing goose wing turning and goose feed directly added with the compound feed additive.
Background
In recent years, with the rapid development of the aquatic livestock breeding industry in China, the goose breeding in China has a huge achievement, and the total breeding amount is the first in the world. Meanwhile, the occurrence and development of high-density and intensive breeding patterns lead to the deterioration of breeding environment, outbreak and epidemic of goose diseases, wherein diseases mainly characterized by the displacement and tilting of wing joints on one side or both sides of growing geese (mostly starting at 35 days of age), namely, the so-called 'goose wing flapping' appear. The feather is prevented from developing after the wings turn over, and the normal commercial value is not achieved; in addition, the male goose mating and the female goose natural hatching are influenced, and the male goose can not be reserved for breeding; geese fed with fat livers will occupy more cages or rub against each other to generate stress to affect growth. Therefore, the disease brings great economic loss to goose breeding.
The research suggests that goose fin turning disease is a disease which frequently occurs in intensive goose culture in recent years and takes goose nutritional metabolism disorder as a main cause and possibly takes environment and heredity as secondary influence factors. The epidemic season of the disease mainly occurs in the early spring or autumn of the growth stage from the end of the brood of the gosling, and mainly occurs in 35-55 days old, no matter how many goose species occur, especially in local China. Once the goose suffers from the disease, the disease is difficult to treat, and the incidence rate can reach 35 percent or even higher.
In recent years, researches on prevention and treatment of goose fin turning have been reported, but the researches are isolated, single and even misguided. Zhou Jing Ming et al (2003) reported that goose wings are turned due to imbalance of the ratio of calcium to phosphorus in daily ration, mineral deficiency is easy to occur particularly under the condition of serious calcium deficiency, the contents of calcium and phosphorus in the daily ration are respectively recommended to be 0.8-1.2% and 0.4%, sports and grazing are enhanced, and multiple sunlight is favorable for preventing the disease. Wanxi white goose male and female geese reported by Wanxi white goose (2015) have higher wing turning rate than Roman geese, the peak of absolute weight gain of Wanxi white goose is about 5 weeks, the female goose is about 6 weeks, and the growth rates of two goose species are reduced after 8 weeks. The method is consistent with the occurrence of the difference and the occurrence time of the variety of the goose wing turning. Tangyuanyi (2009) reports that if the shrunken wheat is fed singly, the ratio of calcium to phosphorus is only 1: 0.15 (actually, the ratio of phosphorus to calcium), and the incidence rate of goose wing turning can reach 2/3. The grazing is strengthened, and the sun is shone more, which is beneficial to preventing the disease.

Application example 1 the additive of the invention is used for preventing winging disease of Wanxi white geese in wheat area
By adding different additives, the prevention effect of Wanxi white goose growth and fin turning is researched. The powder or granulated feed prepared from corn, wheat, bean pulp, rapeseed meal, salt, stone powder and the like is used as a control group, different additives are added into the control group in the test group, and the additive added into the test group I is prepared by the method of example 4 and is added by 10 percent; test group II was prepared as in example 6, with 10% addition; the farm group is fed with corn and wheat coarse powder. The test goose is a white Wanxi goose, the average weight of 1408 male and female geese in 30 days old is about 2055.5 +/-38.5 g, the goose is fed to 4 groups randomly, 4 repetitions are arranged in each group, and each repetition is 88 (each half of male and female geese) and 16 independent rings are needed. After 5 days of pre-feeding, entering a formal test until the age of 70 days is finished. The test results are as follows:
table 1 shows the occurrence of wing turning of geese in each group X +/-SD; n is 4
Note: in the table, the same column of data shows significant difference (P < 0.05) due to different letters on the right shoulder, extremely significant difference (P < 0.01) due to alternate letters, and insignificant difference due to the same letters; in the table, "proportion of male geese" and "proportion of female geese" refer to the percentage average of the number of occurrences in each repetition in the number of tested geese in each repetition; the same is as follows.
The results in table 1 show that the goose tested by the feed additive can greatly reduce the incidence rate of the fin turning disease compared with the farm group goose, wherein the enzyme preparation group (test II group) has better effect than the non-added group, and is estimated to be related to the improvement of the nutrient digestibility of daily ration and the improvement of the absorption and deposition of key nutrients; compared with a farm group, the wing turning rate can be greatly reduced if a compound feed (a control group) with relatively complete nutrition is used without adding additives; under the same daily ration condition, the incidence rate of the wing turning of the male goose is lower than that of the female goose.
Application example 2 additive of the invention for preventing winging disease of Aroman geese
By adding different additives, the prevention effect of the growth and the fin turning of the Aroman goose is researched. The powder or granulated feed prepared from corn, wheat, bean pulp, rapeseed meal, salt, stone powder and the like is used as a control group, different additives are added into the control group in the test group, and the additive added into the test group I is prepared by the method of example 4 and is added by 10 percent; test group II was prepared as in example 6, with 10% addition; the farm group is used for feeding corn and wheat coarse powder. The test goose is a white roman goose, 1408 male and female geese with the age of 30 days are selected, the average weight of each half of the weight is about 2242.5 +/-39.9 g, the goose is fed to 4 groups randomly, 4 repetitions are arranged in each group, and each repetition is 88, so that 16 independent small circles are needed. The test was terminated by 70 days of age. The test results are as follows:
table 2 tests the occurrence of fin turning X ± SD of each group of geese; n is 4
The results in table 2 show that the feed additive can remarkably reduce the incidence rate of the fin turning disease of the Aroman geese compared with a control group, wherein the enzyme preparation adding group (test II group) has better effect than the group without the enzyme preparation adding group (test I group), and is estimated to be related to the improvement of the nutrient digestibility of the ration; the wing turning rate can be obviously reduced compared with a farm group without adding additives if a compound feed (a control group) with relatively complete nutrition is used.
By combining the table 1 and the table 2, the incidence rate of the fin turning of the white roman geese is obviously lower than that of the Wanxi white geese under the condition that the nutrition background of the ration of a control group or a farm group is the same, and the European variety geese are more resistant to coarseness.
Application example 3 the additive of the present invention was used to prevent fin-turning of rice-field Wanxi white geese
By adding different additives, the prevention effect of growth and fin turning of the Wanxi white geese in the rice area is researched. Application examples 1 and 2 are northern wheat producing areas, but the present example is applied to southern rice producing areas. The powder or granulated feed prepared from corn, rice, bean pulp, rapeseed meal, salt, stone powder and the like is used as a control group, different additives are added into the control group in the test group, and the additive added into the test group I is prepared by the method of example 5 and is added by 10 percent; test group II was prepared as in example 7, with 10% addition; the farm group is fed with corn and rice coarse powder. The test goose is a white Wanxi goose, 1408 male and female geese with the age of 30 days are selected, the average weight of each half of the male and female geese is about 2064.5 +/-37.5 g, the goose is fed to 4 groups randomly, 4 repetitions are arranged in each group, and each repetition is 88, so that 16 independent small circles are needed. The test was terminated by 70 days of age. The test results are as follows:
table 3 shows the occurrence of fin-turning X + -SD in each group; n is 4
The results in table 3 show that the feed additive of the invention can also significantly reduce the incidence rate of the fin turning disease, wherein the enzyme preparation adding group (test II group) has better effect than the group without the enzyme preparation, and is estimated to be related to the improvement of the nutrient digestibility of the ration; the wing turning rate can be obviously reduced compared with a farm group without adding additives if a compound feed (a control group) with relatively complete nutrition is used.
Compared with northern wheat areas, the rice and the byproduct rice bran thereof are applied, so that the fin turning rate of the Wanxi white goose can be further reduced, and the method is probably related to the main production of the rice in the Wanxi area where the variety of goose lives for a long time. In addition, the wing turning incidence of the female goose is higher than that of the male goose.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents and improvements made within the spirit and principle of the present invention are intended to be included within the scope of the present invention.
