Problems solved by technology

However, the silage feed prepared by this method is too thick and has poor palatability, so it cannot be directly fed to fattening pigs, and the process needs to be further improved for feeding fattening pigs

Embodiment 1

[0043] Example 1: Special high-efficiency mill for green storage of whole-plant corn

[0044] Such as Figure 1-4 As shown, a green-storage whole-plant corn high-efficiency crusher includes a hopper 1, a crushing box 2, a driving device and a frame 3. The crushing box 2 is provided with a crushing mechanism, the crushing box 2 and the drive The devices are all fixed on the frame 3. There are two crushing boxes 2, the lower end of the feed hopper 1 is provided with two feed outlets 4, the upper part of the two crushing boxes 2 are both provided with a crushing inlet 5, the two feed outlets 4 and The crushing inlets 5 of the two crushing boxes 2 are respectively connected, and the lower part of the crushing box 2 is provided with a crushing outlet 6.

[0045] The crushing mechanism includes a blade holder 8 and a rotating shaft 7. The two ends of the rotating shaft 7 extend out of the crushing box 2 and are respectively connected to the frame 3 through bearings. One end of the rota...

Embodiment 2

[0055] (1) Harvesting: The harvesting time of the whole plant of corn should be between mid-milk to early maturity of corn kernels, or when the solid embryo line (milk line) of the corn kernel reaches 1 / 2 and pits appear in some corn seeds; The height of stubble should be controlled 15~20cm;

[0056] (2) Transportation: the corn stalks are required to be transported to the green storage yard immediately after harvesting;

[0057] (3) Short-cut: The corn stalks that have been transported are first processed by the straw-cutting machine, and then cut into 5cm;

[0058] (4) Efficient pulverization: After being short, it is sent to the high-efficiency pulverizer, and the whole corn stalk is cut into particles with a length of 0.5cm through the high-speed cutting of the cemented carbide pulverizing blade at a speed of 1470r / min;

[0059] (5) Filling and compaction: immediately fill the crushed raw materials in the fermentation tank. The moisture content of the raw materials in the green st...

Embodiment 3

[0061] Example 3 Diet preparation

[0062] 35~60kg stage lean meat-type growing and fattening pigs, the test group formula: green storage whole plant corn feed (calculated by air-dry matter) 30%, corn 50%, soybean meal 15.9%, phytase (Beijing Challenge Company) 0.1%, pre Mixture 4%; control group formula: corn 65%, soybean meal 20%, bran 11%, premix (Shandong Anchi Group) 4%.

[0063] 60~90kg stage lean meat type growth and fattening pigs, test pig formula: Green storage whole plant corn feed (calculated by air-dry matter) 30%, corn 45%, soybean meal 10.9%, bran 10%, phytase (Beijing Challenge Company ) 0.1%, premix 4%; control formula: corn 60%, soybean meal 16%, bran 20%, premix 4%.

[0064] Preparation and use method: Calculate the dosage based on the water content of the whole plant corn feed in Green Store. According to the formula ratio, first add the whole plant corn feed in Green Store to the mixer. While stirring, add other raw materials. The amount of each mixing is the mi...

Abstract

The invention discloses special daily ration for lean type growing-finishing pigs and a preparation method thereof. The daily ration for lean type growing-finishing pigs in the stage of weight being 35-60kg contains the following ingredients in percent by weight: 30 percent of whole-plant corn silage feed (according to air dry matter), 50 percent of corns, 15.9 percent of bean pulp, 0.1 percent of phytase and 4 percent of premix. The daily ration for lean type growing-finishing pigs in the stage of weight being 60-90kg contains the following ingredients in percent by weight: 30 percent of whole-plant corn silage (according to air dry matter), 45 percent of corn, 10.9 percent of bean pulp, 10 percent of bran, 0.1 percent of phytase and 4 percent of premix. The silage whole-corn feed is prepared by crushing newly-harvested whole-plant corns into particles with the length being about 0.5cm and then conducting closed fermentation. The daily ration is used, so that the straw feed resource can be fully utilized, the growth speed of pigs is increased, and the feeding cost is significantly reduced. Moreover, excrement odor is reduced, and the feeding environment of pigsty is improved.

Description

Technical field [0001] The invention relates to a special diet for lean growth and fattening pigs and a preparation method thereof, and belongs to the technical field of feed. Background technique [0002] There are many restrictive factors in my country's intensive pig production. Among them, the outstanding performance is that the price of feed ingredients has increased too fast, and the prices of corn and soybean meal have risen by more than 20%. At present, my country's feed rations generally refer to the NY / T65-2004 standard, which is formulated on the basis of corn-soybean meal rations. The sharp increase in the price of raw materials leads to increased feed costs and reduces the efficiency of pig raising. At the same time, some unconventional raw materials are obviously under-utilized in production, and there are even wasteful discards. [0003] Green storage of whole-plant corn technology has been widely used in feeding ruminants such as dairy cows and mutton sheep, and ha...
