Description

Technical Field

[0001] The invention relates to the technical field of animal breeding feed, and in particular to a healthy and efficient compound feed for Canadian sows. Background Art

[0002] As a high-quality pig breed, Canadian sows have significant advantages and characteristics in the pig farming industry. Canadian sows occupy an important position in the pig farming industry with their excellent body shape, good reproductive performance, high-quality meat quality, strong adaptability and disease resistance. For pig farms, choosing Canadian sows as a breeding breed will help improve production efficiency and economic benefits.

[0003] In the modern pig farming industry, improving the reproductive performance and production efficiency of sows is the key to improving the economic benefits of pig farms. However, during the reproductive cycle of sows, especially during the lactation stage, sows often face the problem of severe back fat loss due to genetic high litter size, high weaning weight, and insufficient sow lactation. Secondly, in terms of batch feeding management level, they also face challenges in refined management. Various production indicators such as litter size, weaning number, and litter weight gain need to be continuously broken through to improve the quality of weaned piglets. The reproductive competitiveness of high-yield sows has ushered in new challenges. This not only affects the lactation ability and health status of sows, but is also directly related to their estrus speed after weaning and their production performance in the next reproductive cycle.

[0004] The key to ensuring the production efficiency of high-yield lactating sows is to consider the maximum milk secretion and substantial quality of sows, as well as to reduce the loss of sow backfat and reduce the impact of low-parity culling on performance. Appropriate fat condition can increase the estrus rate of sows after weaning for 7 days. Due to the physical selection constraints of Canadian pigs, research on improving the feed intake, precise nutrition, and healthy nutrition of Canadian lactating sows has become a hot topic. Indicators such as feed intake during lactation, backfat loss, piglet growth performance, and economic benefits are investigated to achieve the maximum nutrient intake of lactating sows, formulate healthy and efficient diets for sows that match the target performance of high-yield lactating sows to maximize litter weight, and extend the parity of sows. It is particularly important to regulate nutrition to improve the quality of piglets produced throughout the life. Summary of the invention

[0095] Effect verification:

[0096] Test sample: the healthy and efficient compound feed for Canadian sows provided in Example 3 and Comparative Example 1 of the present invention.

[0097] Experimental method: Through the effects of different feeds on the sows' feed intake at each stage of lactation, the whole period, and the backfat loss, and the effects of different feeds on the growth performance and economic benefits of piglets, the weekly feed intake of sows, the average feed intake of sows during lactation, the sows' backfat loss, the weaning weight of piglets, and the weaning litter weight of piglets were verified. The experiment was conducted at the Taikun Agricultural and Animal Husbandry Breeding Pig Farm in Changji Prefecture, Xinjiang, with 40 sows in each group. The results are shown in Tables 2 and 3 below.

[0098] Table 2 Effects of different diets on feed intake and backfat loss at different lactation stages of sows

[0099]

[0100]

[0101] Table 3 Effects of different diets on growth performance and economic benefits of piglets

[0102]

[0103] From Table 2 and Table 3, we can see that:

[0104] By applying the healthy and efficient compound feed of the present invention and feeding according to the method of gradually increasing the feed amount after delivery, the weaning litter weight of sows and the average feed intake of sows during lactation can be increased, and at the same time, the back fat loss and the feed cost of weaning litter weight gain per kilogram can be effectively reduced to save costs. Finally, the weaning litter weight, a comprehensive indicator of body weight and number of pigs, shows that the group in Example 3 has better piglet weight gain performance. Calculated at 50 yuan per kilogram of body fat of weaned piglets, the sow increases the benefit by 260 yuan per litter, indicating that the scheme described in the present invention can make sows have better health and reproductive performance. Therefore, it can provide an effective way and method for improving the production efficiency and benefits of current scale pig farms.

[0105] In addition, the results of the embodiments of the present invention show that 1) the weight of the fermented soybean meal in the healthy and efficient compound feed of the present invention is controlled to 50-90 parts, and the acidulant composed of lactic acid, citric acid, fumaric acid and silicon dioxide is added to replace the original benzoic acid and five grain acid to increase the feed intake of sows and improve the growth performance of piglets; 2) under the condition of meeting the nutritional needs of lactating sows, reducing the balance level of crude protein, energy and amino acids in the healthy and efficient compound feed of the present invention can save feed consumption costs, but the back fat loss has a tendency to increase; 3) according to The intake of various nutrients is calculated based on the feed intake of the sows throughout the whole period, which proves that the exogenous functional amino acids of the present invention have a critical effect on lactation performance. Adjusting the types of amino acids in the healthy and efficient compound feed of the present invention is likely to reduce the digestibility and utilization of nutrients, which ultimately manifests in poor production performance; 4) The lactation performance of sows tends to be positively correlated with the backfat loss. The lactation performance of sows can be improved by increasing the feed intake or improving the nutritional level of the feed. At the same time, a reasonable increase in the backfat loss may increase the estrus rate of sows after weaning and the utilization rate of sows.

[0106] Furthermore, the use of the healthy and efficient compound feed for Canadian sows provided in Examples 1 and 2 of the present invention for feeding can also increase the litter size, weaning number, weaning litter weight, average feed intake of lactating sows, and estrus rate within 7 days after weaning, and can also effectively reduce the incidence of constipation in pregnant sows; the effect is not as good as the feeding effect of Example 3 of the present invention, but is worse than Comparative Example 1. The use of the healthy and efficient compound feed for Canadian sows provided in Comparative Example 2 for feeding is equivalent to that of Comparative Example 1.

[0107] It can be known from the effect verification experiment that, on the one hand, the healthy and efficient compound feed of the present invention adopts a combination of fiber structure, probiotic powder, fermented composite raw materials and yeast cell wall, which can relieve sow constipation and improve intestinal health to the greatest extent, thereby improving the growth performance of piglets to the greatest extent. On the other hand, the healthy and efficient compound feed of the present invention is a low-protein, high-energy, high-immune amino acid balance design, which can promote the recovery of sows' postpartum feed intake and reduce body fat loss, and can increase the concentration of threonine, valine and isoleucine in plasma to improve the quality of lactation, and ensure that the weight loss of sows during lactation is small, thereby achieving the lifelong parity of sows with high reproductive performance, providing a higher total weaned piglet quality, and improving production economic benefits. On the other hand, the present invention achieves the purpose of improving the efficiency of healthy breeding, extending the parity of sows, and improving the contribution of lifelong piglet quality by designing the feeding value of healthy and efficient compound feed, protecting intestinal health, enhancing animal immunity, and reducing body fat loss, and the healthy and efficient compound feed is stable in compatibility with the sows of the same line. On the other hand, the present invention adopts feed intake control technology in the formula design of healthy and efficient compound feed. By regulating the protein and energy sources in the feed of lactating sows, the fermented protein content in the feed is increased to ensure that the corresponding organic acids, fats, proteins, and oligosaccharides in the feed can be more efficiently utilized by the sows and converted into components of breast milk, while also promoting the lactation quality of the sows.
