[0002] Pig feed additives refer to various trace substances added to pig feed to improve the nutritional value of feed, promote the growth and health of pigs, and prevent diseases. Adding feed additives to piglet diets can promote intestinal development, improve intestinal health, reduce diarrhea rate, and increase piglet growth rate and feed conversion rate. Using feed additives in sow diets can improve intestinal health, immunity and reproductive performance of sows. Adding feed additives to fattening pig diets can reduce the diarrhea rate of fattening pigs, improve immunity, increase feed intake and feed digestibility, thereby improving diet utilization and reducing feed-to-meat ratio. Depending on different feeding needs, the selected pig feed with different additives will also be very different.

[0003] The Chinese invention patent CN117322515B specification discloses an environmentally friendly pig feed additive, feed and preparation method thereof. The environmentally friendly pig feed additive provided by the patent includes plant extracts, algae extracts and bone meal; the weight ratio of the plant extracts, algae extracts and bone meal is 10-15:3-5:7-9; the plant extracts include at least one of grapefruit peel extract, fennel extract, spinach extract, rose petal extract, eggplant peel extract, lemon peel extract and banana peel extract; the algae extracts include spirulina extract, triangular brown finger algae extract and boat-shaped algae extract, wherein the weight ratio of the spirulina extract, triangular brown finger algae extract and boat-shaped algae extract is 1:1:1; the bone meal includes cattle bone meal, pig bone meal and chicken bone meal. The pig feed provided by the present application is rich in nutrition, can improve the immunity of the pig herd, and can better promote the growth of the pig herd.

[0004] The specification of Chinese invention patent CN118160815B discloses a feed additive for fattening pigs for improving pork quality and producing selenium-enriched pork. It records that the feed additive contains Prevotella copri, which can promote the increase of selenium and selenoprotein content in pork and significantly reduce the drip loss of pork. In particular, the combined use of Prevotella and serine can synergistically promote selenium deposition in pork, which is used to improve pork quality and produce selenium-enriched pork.

[0005] However, farms usually raise multiple types of pigs at the same time, including piglets, sows, and fattening pigs.

[0035] The following describes six implementation methods of the present application in detail with reference to the accompanying drawings.

[0036] The first implementation method:

In addition, the packaging setting of gelatin film can protect the environment and avoid the use of excessive plastic packaging to cause environmental pressure. At the same time, the water-soluble property of gelatin film can be used to increase the portability of pig feed additives during application, reduce feeding difficulty, and improve feeding efficiency.

[0058] Taking a single production line of a pig feed additive manufacturer as an example, the manufacturing cost is calculated. The cost of a set of medium-sized feed processing equipment is RMB 500,000, plus the annual labor cost of RMB 300,000 (5 workers, with an average monthly salary of RMB 5,000). This set of production line equipment can produce 1,000 tons (i.e. 1,000,000 kg) of pig feed per year. It can be calculated that the total production cost is RMB 0.8 / kg. The cost table 1 of the pig feed additive in this embodiment is as follows, in RMB / kg:

At the same time, the water-soluble property of gelatin film can be used to increase the portability of pig feed additives during application, reduce feeding difficulty, and improve feeding efficiency.

[0074] In the fourth and fifth embodiments, the preparation manufacturer described in the third embodiment is also taken as an example, and the cost table 2 of the pig feed additive is as follows, in units of yuan / kg:

[0075] Cost table 2 of pig feed additives

[0076]

[0077]

[0078] According to the above-mentioned cost table 1 of pig feed additives, it can be concluded that the selling price of pig feed additives for piglets is 4-7 yuan / kg, the selling price of pig feed additives for sows is 5-8 yuan / kg, and the selling price of pig feed additives for fattening pigs is 7-12 yuan / kg.

[0079] The sixth implementation method:

[0083] A2. When feeding sows, select a certain amount of the main ingredient additive composition, the secondary ingredient additive composition and the Class B replacement component according to the number of sows, and use the main ingredient additive composition, the secondary ingredient additive composition and the Class B replacement component in a ratio of 2:2:1. After the additive composition, the secondary ingredient additive composition and the replacement ingredient additive composition packaged in gelatin film are dissolved in water, they are sprayed on the feed of the sows;

[0084] A21. When the auxiliary ingredient composition is used in feeding sows, the Class B auxiliary ingredient in an independent package can be selected, or the Class B auxiliary ingredient in a separate package with the Class B replacement ingredient can be selected, and the main ingredient additive composition, the secondary ingredient additive composition, the Class B replacement ingredient and the Class B auxiliary ingredient are mixed in a ratio of 2:2:1:1, and the gelatin film-packaged additive composition, the secondary ingredient additive composition and the replacement ingredient additive composition are dissolved in water and sprayed on the feed of the piglets;

[0085] A3. When feeding fattening pigs, select a certain amount of the main ingredient additive composition, the secondary ingredient additive composition and the Class C replacement component according to the number of fattening pigs, and use the main ingredient additive composition, the secondary ingredient additive composition and the Class C replacement component in a ratio of 3:3:1. After the additive composition, the secondary ingredient additive composition and the replacement ingredient additive composition packaged in gelatin film are dissolved in water, they are sprayed on the feed of the fattening pigs;

[0086] A31. When using an auxiliary ingredient composition in feeding piglets, you can choose a Class C auxiliary ingredient in an independently packaged package, or you can choose a Class C auxiliary ingredient in a separate combination package with a Class C replacement ingredient, and use the main ingredient additive composition, the secondary ingredient additive composition, the Class C replacement ingredient and the Class C auxiliary ingredient in a ratio of 3:3:1:1. After dissolving the additive composition, the secondary ingredient additive composition and the replacement ingredient additive composition packaged in gelatin film in water, spray them on the piglet feed. The combined use of pig feed additives and universal pig feed can effectively reduce the difficulty of workers carrying feed during feeding and reduce the labor intensity of workers. It can also effectively promote feeding efficiency and reduce the labor cost of pig farming.

[0087] The experimental data shows that a medium-sized pig farm was selected for comparison of the breeding costs for 6 months. The farm has 50 piglets, 20 sows and 200 fattening pigs. Each piglet consumes about 0.3 kg of special feed per day. The purchase price of piglet special feed is 130 yuan / bag, and a bag of 40 kg. Each sow consumes about 3 kg of special feed per day, and the special feed for sows is 150 yuan / bag, and a bag of 40 kg. Each fattening pig consumes about 3.5 kg of special feed per day, and the special feed for fattening pigs is 100 yuan / bag, and a bag of 40 kg. Generally, 4 workers are required to carry out daily management of the farm, and feeding is required 3 times a day, and each feeding takes about 2 hours. The general pig feed on the market is generally 90 yuan / bag, and a bag of 40 kg. When feeding, choose a suitable ratio of pig feed additives and mix them with general pig feed, and the mixing ratio is 3:1. This experiment conducted a half-and-half feeding comparison on the pigs in the medium-sized pig farm. Two workers used the existing special feeding mode to feed half of the pigs normally (recorded as Z-type feeding), and two workers chose to use the feeding mode of general feed and pig feed additives to feed the other half of the pigs (recorded as T-type feeding). The specific feeding cost comparison table (yuan) and feeding efficiency comparison table (hours) are as follows:

[0088] Feeding cost comparison table

[0089]

[0090] According to the above feeding cost comparison table, it can be known that when raising piglets and sows, the use of general feed combined with pig feed additives can effectively reduce feeding costs, but when raising fattening pigs, the use of special fertilizers can save more feeding costs. Farms can choose appropriate feeding methods based on their own pig breeding conditions, and the costs in "()" in the above feeding cost comparison table are the total prices after selecting the auxiliary ingredient composition.

[0091] Feeding efficiency comparison table

[0092]

[0093] According to the above feeding efficiency comparison table, it can be known that the feeding efficiency is greatly reduced. The selection of general feed and pig feed additives can effectively improve the feeding efficiency and feeding difficulty, thereby reducing labor costs in the subsequent breeding process, and further promoting the economic benefits of pig feeding. According to feeding observations, the growth status of pigs under the two feeding modes is not much different, thereby promoting the economic benefits and costs of pig breeding by reducing feeding costs.

[0094] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
