Problems solved by technology

Increasing the energy supply can increase the speed of weight gain and feed conversion rate, but it will cause the carcasses of fattening pigs to be too fat; if the energy level in the feed is too low, the weight gain will be slow
Feed conversion ratio is too low

preparation example Construction

[0049] The preparation method of the pig fattening period compound feed, comprises the steps:

[0050] Step 1. Heat-treat the rice bran, distiller's grains, rapeseed cake and bean cake at 105°C for 4 hours. After cooling, crush them through a 60-mesh sieve to obtain a pretreated base material;

[0051] Heat treatment causes changes in the molecular structure of the protein in the base material (rice bran, distiller's grains, rapeseed cake and bean cake) and other substances (such as the peak area ratio of the amide I band to the amide II band and the peak height ratio of α-helix and β-sheet) Change the protein solubility and the utilization of protein molecular structure by gastrointestinal microorganisms and proteolytic enzymes, thereby improving the small intestine digestibility of crude protein and improving the digestion and absorption of crude protein by pigs;

[0052] Step 2. Fully mix the fermented corn germ meal, pretreated base material, fish meal, meat and bone meal,...

Embodiment 1

[0055] Pig fattening compound feed is made of the following raw materials by weight: 40 parts of fermented corn germ meal, 20 parts of rice bran, 15 parts of distiller's grains, 10 parts of rapeseed cake, 10 parts of bean cake, 12 parts of Chinese herbal medicine preparation, 5 parts of fish meal, 4 parts of meat and bone meal, 7 parts of corn oil, 1 part of table salt, 1 part of green tea powder, 0.8 parts of fermented polysaccharide, and a small amount of additives;

[0056] The preparation method of the pig fattening period compound feed, comprises the steps:

[0057] Step 1. Heat-treat the rice bran, distiller's grains, rapeseed cake and bean cake at 105°C for 4 hours. After cooling, crush them through a 60-mesh sieve to obtain a pretreated base material;

[0058] Step 2. Fully mix the fermented corn germ meal, pretreated base material, fish meal, meat and bone meal, corn oil, salt, green tea powder, fermented polysaccharide and additives, and process the evenly mixed feed...

Embodiment 2

[0061] The pig fattening period compound feed is made of the following raw materials by weight: 45 parts of fermented corn germ meal, 25 parts of rice bran, 18 parts of distiller's grains, 12 parts of rapeseed cake, 13 parts of bean cake, 14 parts of Chinese herbal medicine preparation, 6 parts of fish meal, 5 parts of meat and bone meal, 8 parts of corn oil, 1.5 parts of table salt, 1.5 parts of green tea powder, 1 part of fermented polysaccharide, and a small amount of additives;

[0062] The preparation method of the pig fattening period compound feed, comprises the steps:

[0063] Step 1. Heat-treat the rice bran, distiller's grains, rapeseed cake and bean cake at 105°C for 4 hours. After cooling, crush them through a 60-mesh sieve to obtain a pretreated base material;

[0064] Step 2. Fully mix the fermented corn germ meal, pretreated base material, fish meal, meat and bone meal, corn oil, salt, green tea powder, fermented polysaccharide and additives, and process the eve...

Abstract

The invention discloses a formula feed for the pig fattening period.The formula feed is prepared from, by weight, 40-50 parts of fermented corn germ meal, 20-30 parts of rice bran, 15-20 parts of drydistiller's grains, 10-15 parts of rapeseed cake, 10-15 parts of bean cake, 12-16 parts of a Chinese herbal medicine preparation, 5-8 parts of fish meal, 4-6parts of meat and bone meal, 7-10 parts ofcorn oil, 1-2 parts of salt, 1-2 parts of green tea powder, 0.8-1.2 parts of fermented polysaccharides and a trace amount of additives.The invention further disclosesa preparation method of the formula feed for the pig fattening period.Accordingly, the fermented corn germ meal serves as the main feed material, the fermented corn germ meal has the functions of achieving digestion and absorption easily and promoting growth, the surface of the feed is wrapped with a layer of Chinese herbal medicine preparation,the obtained feed has the effects of achieving the anti-bacterial property, diminishinginflammation, enhancing immunity, maintaining the balance of gastrointestinal microflora and the like, the nutritional requirements of fattening pigs in the growth period can be fully met, the fattening pigs can grow rapidly, the meat quality is obviously improved, and the disease resistance is high.

Description

technical field [0001] The invention belongs to the technical field of pig feed, and in particular relates to a compound feed for pig fattening period and a preparation method thereof. Background technique [0002] The organs of the pigs in the growing and finishing stage are mature, and the resistance to the external adverse environment is also enhanced. The probability of disease in this stage of pigs is reduced, and it is relatively easy to raise. That’s enough, but to pursue a higher feed return at this stage, to achieve the purpose of increasing the daily weight gain of pigs, improving the quality of pork, reducing costs, and shortening the time for slaughter, with the least investment, the production volume is large and High-quality pork is supplied to the market. [0003] The characteristic of fattening pigs is that all organs, tissues, systems and functions of the body have been fully developed, especially the digestive system has undergone great changes, and it can...
