Feed additive capable of obviously improving ostrich laying rate

Abstract

The invention discloses a feed additive for improving the ostrich laying rate. The feed additive is prepared from herba portulacae, rhizoma atractylodis, manis pentadactyla linnaeus, malachium aquaticum, rape pollen, shell powder, white fish meal and pumpkin seed linseed oil; the feed additive is prepared through the steps of preparing aqueous extraction solution through aqueous extraction, collecting volatile oil, smashing the materials in powder, decompressing, concentrating, stirring and mixing; the feed additive is added into daily feed of ostriches to be used for improving the ostrich laying rate. The feed additive can obviously reduce ostrich stress reaction, can meet the requirement of ostrich parturition and egg laying for calcium and phosphorus, can guarantee protein and selenium intake, can prevent feed from mildewing, can improve omega-3PUFA in ostrich eggs and reduce the proportion of omega-6 / omega-3PUFA, further can improve the immunity of the ostriches and reduce the morbidity of bird flu, shortens the sexual maturity time and prolongs the egg laying peak, can obviously reduce the feeding cost, improves the laying rate and the quality and has great market development and application prospect.

Description

technical field [0001] The invention relates to the technical field of ostrich breeding, in particular to a feed additive for significantly improving the egg production rate of ostriches. Background technique [0002] The African ostrich is the largest existing bird in the world. Artificial breeding began in Africa in the 19th century, and expanded to Europe, America, and Asia in the 1980s. It was introduced into my country in the 1990s and has been artificially raised on a large scale. There are about 50,000 domestic stocks. Ostrich meat is nutritious and delicious, and ostrich skin is comparable to crocodile skin. Especially in recent years, the edible value of ostrich eggs has been promoted more and more. Ostrich eggs are the most eggs. As the "King of Eggs", the egg whites of ostrich eggs are crystal clear, and the eggs are golden yellow and attractive.

[0002] The African ostrich is the largest existing bird in the world. Artificial breeding began in Africa in the 19th century, and expanded to Europe, America, and Asia in the 1980s. It was introduced into my country in the 1990s and has been artificially raised on a large scale. There are about 50,000 domestic stocks. Ostrich meat is nutritious and delicious, and ostrich skin is comparable to crocodile skin. Especially in recent years, the edible value of ostrich eggs has been promoted more and more. Ostrich eggs are the most eggs. As the "King of Eggs", the egg whites of ostrich eggs are crystal clear, and the eggs are golden yellow and attractive. The nutritional value of ostrich eggs is "soft gold", and it is the first choice for "food supplements" to enhance physical fitness and improve immunity. Long-term consumption can have the effects of beautifying, strengthening yang, increasing intelligence, prolonging life, and reducing blood lipids and blood sugar; The rising cost has led to an increase of 20%-30% in the cost of breeding ostriches. Both domestic and international ostrich industries are facing great challenges. Therefore, how to reduce the cost of breeding, improve the egg production level of ostriches and the qualified rate of breeding eggs, etc., become an ostrich The key to a successful farm operation

[0003] The full price of feed nutrition is the premise to ensure the egg production rate of ostriches. If the feed ratio is out of balance, the trace elements are insufficient, the vitamins and essential amino acids are lacking, and the feed is mildewed, it will lead to a decline in the egg production rate; The physical energy consumption during laying is relatively large, and insufficient energy intake will also cause a decline in egg production rate, especially when the protein content or effective amino acid content in the feed is insufficient, it will cause a decline in egg production rate, while the feed in the prior art , although the ratio of protein and amino acid is constantly increasing, while increasing the cost of feed, it does not increase the absorption rate of effective nutrients, and it is easy to cause various chronic diseases such as gout, but affects ovarian development. Excessive dietary fat or saturated fatty acid and The imbalance of the proportion of polyunsaturated fatty acids has an important impact on the occurrence of various chronic diseases; the balance of ω-6 / ω-3 PUFA plays an important role in the normal growth of the body and the stability of the internal environment, which can reduce the occurrence of cardiovascular diseases and other chronic diseases. Reduce egg production rate; on the other hand, Newcastle disease, infectious bronchitis, bird flu and other diseases can cause oviduct atrophy, follicle development hindered reproductive system damage, infectious bacterial diseases can cause follicle deformation, degeneration, infection, resulting in ostrich Decreased egg production rate or even death from illness; based on the above reasons, it is necessary to design and develop a feed additive that can significantly increase the egg production rate of ostriches, so as to improve the economic benefits of ostrich breeding
