Description
Technical Field
[0001] The invention belongs to the technical field of laying duck production, and in particular relates to a composite feed additive for laying ducks and a preparation method and application thereof. Background Art
[0002] Laying ducks generally need to grow to more than 4 months, or about 120 days, before they can start laying eggs. The peak egg-laying period is about 150 to 500 days old, and the egg-laying cycle lasts about 350 days, which is about one year. Depending on the breed, the number of eggs laid is about 200 to 300 per year. Duck eggs contain nutrients such as protein, phospholipids, vitamin A, vitamin B2, vitamin B1, vitamin D, calcium, potassium, iron, and phosphorus. The protein content in duck eggs is equivalent to that in chicken eggs, while the total amount of minerals is far better than that in chicken eggs, especially iron and calcium. In the late egg-laying period, due to the influence of factors such as feed, environment, and disease, the production performance of laying ducks decreases, the egg-laying cycle shortens, and the number of eggs produced decreases. In the past, antibiotics were usually added to the feed to solve the above problems and improve the production performance of laying ducks. Starting in 2020, the Ministry of Agriculture and Rural Affairs will completely ban the addition of antibiotics in feed. Therefore, it is of great practical significance to develop a natural feed additive formula to replace antibiotics to extend the egg-laying cycle of laying ducks and increase the number of eggs. Summary of the invention

[0031]
[0032] Note: Compared with the control group, ** indicates P < 0.01, * indicates P < 0.05, the same below
[0033] According to Table 2, it can be seen that the promoting effect of Millettia spatholobi extract, linseed extract and tannic acid extract on the production performance of Jinding duck, whether added separately in proportion or mixed in proportion, is significantly lower than adding the three mixed in proportion into laying duck feed, especially after Millettia spatholobi extract, linseed extract and tannic acid extract were added into the feed at 0.5% respectively, their effects on the production performance of laying duck were significantly lower than that of the composite feed additive of the three added at 0.5%. It can be seen that the mixed addition of Millettia spatholobi extract, linseed extract and tannic acid extract in proportion is the best means to effectively increase the number of eggs laid by laying ducks and reduce the egg breakage rate and the egg deformity rate.
[0034] Example 2
[0035] Take 0.5kg of Millettia spatholobi extract, 0.4kg of flaxseed extract and 0.1kg of tannic acid extract by weight, mix them thoroughly and prepare a compound feed additive, then add 0.5% of it into laying duck feed. Finally, the content of Millettia spatholobi extract in the feed is 0.25%, the content of flaxseed extract is 0.2% and the content of tannic acid is 0.05%.
[0036] 550 Shaoxing laying ducks from the same batch were divided into 11 groups for feeding, namely, control group, 0.25% Millettia spatholobi extract group, 0.2% flaxseed extract group, 0.05% tannic acid extract group, 0.25% Millettia spatholobi extract + 0.2% flaxseed extract group, 0.25% Millettia spatholobi extract + 0.05% tannic acid extract group, 0.2% flaxseed extract + 0.05% tannic acid extract group, 0.25% Millettia spatholobi extract + 0.2% flaxseed extract + 0.05% tannic acid extract group, 0.5% Millettia spatholobi extract group, 0.5% flaxseed extract group, and 0.5% tannic acid extract group, with 50 Jinding ducks in each group. A semi-enclosed ground-based farming method combining water surface, playground and duck house was adopted. The basic daily diet (pellet feed) of the experimental ducks was formulated in accordance with the requirements of the laying period of ducks and in accordance with GB / T 41189-2021 Nutrient Requirements of Laying Ducks. The basic ingredients and nutritional levels of the feed are shown in Table 1. The formal test began when the average egg production rate of laying ducks was above 50%, and the test period was 3 months.
[0037] Table 3 Effects of different formula feed additives on production performance of Shaoxing laying ducks
[0038]
[0039] According to Table 3, it can be seen that the promoting effect of Millettia spatholobi extract, linseed extract and tannic acid extract on the production performance of Shaoxing ducks, whether added separately in proportion or mixed in proportion, is significantly lower than adding the three mixed in proportion into laying duck feed, especially after Millettia spatholobi extract, linseed extract and tannic acid extract were added into the feed at 0.5%, their effects on the production performance of laying ducks were significantly lower than that of the composite feed additive of the three added at 0.5%. It can be seen that the mixed addition of Millettia spatholobi extract, linseed extract and tannic acid extract in proportion is an effective means to significantly reduce the feed-to-egg ratio and mortality rate of laying ducks and improve the production performance of laying ducks.
[0040] Example 3
[0041] Compound feed additive: Take 0.55kg of Millettia spatholobi extract, 0.3kg of flaxseed extract and 0.15kg of tannic acid extract by weight, mix them thoroughly and prepare a compound feed additive, add 0.5% into laying duck feed, and finally the content of Millettia spatholobi extract in the feed is 0.275%, the content of flaxseed extract is 0.15% and the content of tannic acid is 0.075%.
[0042] 650 Jinding ducks from the same batch were divided into 13 groups for feeding, including a control group and a 0.275% Millettia spatholobi extract group, a 0.15% flaxseed extract group, a 0.075% tannic acid extract group, a 0.275% Millettia spatholobi extract + 0.15% flaxseed extract group, a 0.275% Millettia spatholobi extract + 0.075% tannic acid extract group, a 0.15% flaxseed extract + 0.075% tannic acid extract group, a 0.5% compound feed additive (0.275% Millettia spatholobi + 0.15% flaxseed extract + 0.075% tannic acid extract) group, a 0.7% compound feed additive group, a 0.6% compound feed additive group, a 0.4% compound feed additive group, a 0.3% compound feed additive group, and a 0.2% compound feed additive group, with 50 Jinding ducks in each group. A semi-enclosed ground-based farming method combining water surface, playground and duck house was adopted. The basic daily diet (pellet feed) of the experimental ducks was prepared according to the requirements of the laying period of ducks and GB / T41189-2021 Nutrient Requirements of Laying Ducks. The basic ingredients of the feed are shown in Table 1; the composition and nutritional level are shown in Table 1. The experiment was conducted until all laying ducks finished laying eggs, and the laying days of all laying ducks were recorded:
[0043] Table 4 Effects of different formula feed additives on production performance of Shaoxing laying ducks
[0044]
[0045]
[0046] According to Table 4, it can be seen that the effects of Millettia spatholobi extract, linseed extract and tannic acid extract on extending the egg-laying days and egg-laying quantity of Jinding ducks, whether added separately in proportion or mixed in proportion, are significantly lower than adding the three in proportion to the egg-laying duck feed. It can be seen that the composite feed additive of the present invention can significantly extend the egg-laying cycle of egg-laying ducks and improve the production performance of egg-laying ducks. On this basis, the effects of adding different proportions of composite feed additives on the egg-laying days and egg-laying quantity of Jinding ducks were compared. The results showed that when the addition ratio exceeded 0.3%, the effect on the promotion of production performance increased significantly. When the addition amount exceeded 0.6%, the effect on the egg-laying days and egg-laying quantity entered a plateau period, and the input-output benefit began to decline after the addition amount exceeded 0.5%. Therefore, the optimal addition amount of the composite feed additive is 0.3-0.5%.
[0047] Although the above embodiment describes the present invention in detail, it is only a part of the embodiments of the present invention, not all of the embodiments. People can also obtain other embodiments based on this embodiment without creativity, and these embodiments all fall within the protection scope of the present invention.
