Problems solved by technology

The reasons are mainly as follows: (1) Dietary factors. In order to save costs, feed processing enterprises use a large amount of aged grains to produce and process pig feed. The fatty acids of aged grains are oxidized in large quantities during storage. Long-term feeding of aged grains The feed produced by grains leads to the precipitation of peroxidized oil in pigs; (2) genetic factors, most of the breeding pigs in modern farms are imported from abroad, without the excellent blood of traditional soil pigs, due to the high feed conversion rate. Carcass fat deposition is too fast, under the situation that the content of unsaturated fatty acid in the feed is too much, it is easy to produce soft fatty meat and PSE meat; (3) environmental factors, with the rapid development of domestic industrialization and urbanization, the breeding environment of pig farms, Drinking water sources are polluted to varying degrees, and the body's antioxidant and anti-stress capabilities generally decline

[0039] The nutritional indicators of the late-stage compound feed for fattening pigs described in this example are: crude protein: 15.46%, calcium: 0.66%, total phosphorus: 0.52, crude fiber: 2.89%, lysine: 0.81%, digestible energy: 3294kcal / kg.

[0040] The production and processing techno...

Embodiment 2

[0052] The present embodiment provides a common fattening pig compound feed in the late stage. Compared with Example 1, the fattening pig compound feed is made of the following components in mass ratio: betaine 0.3%, chromium picolinate 0.03%, L-selenomethionine 0.02%, vitamin E 0.02%, vitamin C 0.02%, glycine chelated magnesium 0.08%, potassium chloride 0.2%, corn 62.38%, soybean meal 22.0%, oil bran 5.0%, palm oil 0.8%, crude Bran 6.0%, calcium hydrogen phosphate 0.50%, stone powder 1.20%, sodium chloride 0.45%, premix 1.0%.

[0053] The nutritional indicators of the fattening pig late stage compound feed described in this embodiment are: crude protein: 15.34%, calcium: 0.63%, total phosphorus: 0.57, crude fiber: 2.93%, lysine: 0.81%, metabolizable energy: 3006kcal / kg, Digestible energy: 3241kcal / kg.

[0054] The production and processing technology of the late-stage compound feed for fattening pigs described in this example is the same as that in Example 1.

Embodiment 3

[0056] The compound feed for fattening pigs in the late stage of improving pig body shape and flesh color is made of the following components in mass ratio: 0.4% betaine, 0.05% chromium pyridinecarboxylate, 0.02% L-selenomethionine, and 0.02% vitamin E , vitamin C 0.03%, glycine chelated magnesium 0.10%, potassium chloride 0.2%, corn 62.23%, soybean meal 22.0%, oil bran 5.0%, palm oil 0.8%, coarse bran 6.0%, calcium hydrogen phosphate 0.50%, Stone powder 1.20%, sodium chloride 0.45%, premix 1.0%.

[0057] The nutritional indicators of the fattening pig late stage compound feed described in this embodiment are: crude protein: 15.39%, calcium: 0.68%, total phosphorus: 0.51, crude fiber: 2.77%, lysine: 0.81%, metabolizable energy: 2981kcal / kg, Digestible energy: 3206kcal / kg.

[0058] In order to specifically demonstrate the remarkable effect of the functional feed additive added in the present invention, the applicant has carried out corresponding tests and comparisons, which ar...

The later stage feed is formulated with the following raw materials in mass percentage: 0.2-0.4% of betaine, 0.02-0.05% of chromium pyridine carboxylate, 0.01-0.02% of yeast selenium, 0.01-0.02% of vitamin E, and 0.01-0.03% of vitamin C , magnesium sulfate 0.06‑0.10%, potassium chloride 0.1‑0.2%, corn 64.0‑66.0%, soybean meal 20.0‑22.0%, oil bran 5.0‑6.0%, palm oil 0.8‑1.0%, coarse bran 4.0‑6.0%, Calcium hydrogen phosphate 0.38‑0.50%, stone powder 1.05‑1.20%, sodium chloride 0.40‑0.45%, antioxidant 0.05‑0.07, premix 1.0%.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and in particular relates to a late compound feed for improving the body shape and meat quality of fattening pigs and a processing method thereof. Background technique [0002] Fattening pigs refer to meat pigs with a weight of 60kg to before they are slaughtered. After slaughtering, fattening pigs directly enter the final consumption link. Therefore, the size and meat quality of fattening pigs also directly determine the quality of meat on the consumer's table. From the perspective of feeding management, the dietary level of fattening pigs is a key factor in shaping the body shape of pigs and determining the quality of pork. In recent years, a lot of in-depth research has been carried out on improving the feed remuneration and growth rate of fattening pigs. The concept of precision feeding has been proposed for the nutritional supply of fattening pigs, and the growth potential of fattening pigs...
