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: High-efficiency pulverizer dedicated to green storage whole plant corn

[0044] like Figure 1-4 As shown, a high-efficiency pulverizer for whole plant corn in green storage includes a feed hopper 1, a pulverizing box 2, a driving device and a frame 3, a pulverizing mechanism is arranged in the pulverizing box 2, and the pulverizing box 2 and the driving The devices are all fixedly arranged on the frame 3 . There are two crushing boxes 2, the lower end of the feed hopper 1 is provided with two feeding outlets 4, and the upper parts of the two crushing boxes 2 are provided with a crushing inlet 5, and the two feeding outlets 4 are connected to the The pulverizing inlets 5 of the two pulverizing boxes 2 are connected respectively, and pulverizing outlets 6 are provided at the lower parts of the pulverizing boxes 2 .

[0045] The crushing mechanism includes a blade holder 8 and a rotating shaft 7. The two ends of the rotating shaft 7 stretch out from the crush...

Embodiment 2

[0055] (1) Harvesting: The harvesting time of the whole plant corn should be from the middle stage of corn kernel milk ripening to the early stage of wax ripening, or when the real embryo line (milk line) of corn kernels reaches 1 / 2, and some corn seeds have pits; when harvesting The stubble height should be controlled at 15~20cm;

[0056] (2) Transportation: After corn stalks are harvested, they are required to be transported to the green storage yard immediately;

[0057] (3) Short cutting: the corn stalks transported are cut into 5cm after being cut by the cutting machine;

[0058] (4) High-efficiency crushing: After the cutting is short, it is sent to a high-efficiency grinder, and after the high-speed cutting of the cemented carbide crushing blade at a speed of 1470r / min, the whole corn stalks form particles with a length of 0.5cm;

[0059] (5) Filling and compacting: Immediately fill the crushed raw materials into the fermentation tank. The moisture content of green sto...

Embodiment 3

[0061] Example 3 Diet preparation

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

[0063] 60~90kg lean meat type growing and finishing pigs, the formula of the test pigs: 30% corn feed (according to air-dried matter) of silage whole plant, 45% corn, 10.9% soybean meal, 10% bran, phytase (Beijing Challenge Company ) 0.1%, premix 4%; control group 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 of the green storage. According to the formula ratio, first add the whole corn feed of the green storage into the mixer, and add other raw material...

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 ration for lean-meat growing and finishing pigs and a preparation method thereof, belonging to the technical field of feed. Background technique [0002] There are many restrictive factors in my country's intensive pig production, among which the price of feed raw materials has increased too fast, and the price of corn and soybean meal has 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 rise in raw material prices has led to increased feed costs and reduced pig raising benefits. At the same time, some unconventional raw materials are obviously underutilized in production, and there is even a phenomenon of waste and discarding. [0003] The whole-plant corn technology of silage storage has been widely used in feeding ruminants such as dairy cows and mutton sheep, and has achieved good eco...
