Feed for improving growth performance of fattening pigs and feeding method
Technical Field
The invention relates to the technical field of pig feed, in particular to feed for improving growth performance of fattening pigs and a feeding method.
Background
The growth speed of pigs is high, the daily gain is larger, the obtained breeding economic benefit is higher, but the growth speed of the fattening pigs is slow and the production efficiency is low due to various factors in production, and in addition, the current epidemic of African swine fever seriously influences the production of the pork pigs, and how to improve the growth speed and the production efficiency of the fattening pigs becomes a hot spot for pig raising.
Disclosure of Invention
In view of the above, it is desirable to provide a feed and a feeding method for improving growth performance of fattening pigs. In order to achieve the purpose, the invention adopts the following technical scheme:
in a first aspect, the invention provides a feed for improving growth performance of fattening pigs, which comprises the following components in parts by weight: 700 parts of 500-parts of corn, 220 parts of 150-parts of 43% soybean meal, 180 parts of oil bran, 10-20 parts of stone powder, 10-20 parts of premix, 6-10 parts of calcium hydrophosphate, 0.03-0.1 part of glycocyamine, 0.1-0.3 part of vitamin E and 9960.1-0.2 part of Boshengkang.
Preferably, the feed further comprises: 20-30 parts of almond, 10-15 parts of white paeony root, 30-40 parts of flaxseed, 20-40 parts of honeysuckle and 0.2-0.8 part of zymosan.
Optionally, the feed further comprises: 30-40 parts of green tea powder, 20-30 parts of fish meal, 50-60 parts of rapeseed cakes, 40-60 parts of sesame straws, 15-25 parts of liquorice and 10-50 parts of pepper seeds.
Further, the premix comprises lysine, sodium chloride, choline chloride, vitamins, threonine, solid methionine and tryptophan.
Further, the premix comprises the following components in parts by weight: 5 parts of lysine, 5 parts of sodium chloride, 1 part of choline chloride, 1 part of threonine, 0.6 part of solid methionine, 0.08 part of tryptophan and 2 parts of vitamin compound package.
Further, the vitamin complex package comprises VA, VD3, VE, VK, VB3 and VB 12.
In the above feed, guanidinoacetic acid is a precursor of creatine. Creatine phosphate containing high phosphate group transfer potential is widely present in muscle and nerve tissues and is a main energy supply substance in animal muscle tissues. The glycocyamine is additionally added, so that the body generates a large amount of phosphate group transfer substances (phosphocreatine), thereby providing power for the efficient work of tissues such as muscles, brains, gonads and the like and promoting the energy to be continuously distributed to the muscle tissues. The creatine phosphate exists in muscle and nerve tissues in great amount, and has very low fat tissue content, so that it can promote energy transfer to muscle tissue, and has obvious body shape improvement, wide back and plump buttocks. Creatine supplementation reduces mitochondrial free radical production, and results in better flesh color and flesh quality, accelerates ATP synthesis in muscle, and reduces heat stress in animals during transport, herding, and the like. The glycocyamine is used for pigs at the stage of 50-100kg, the meat-feed ratio is reduced by 0.2, the growth and fattening are advanced for 7-10 days, and each pig saves more than 15kg of feed. The glycocyamine is finally metabolized out of the body by an animal body in the form of creatinine, no residue is left in the body, the toxic and side effects of a plurality of prohibited drugs such as clenbuterol and the like are effectively overcome, and the safety is good.
The compound micro-ecological preparation Boshengkang 996 is a commercial product, and mainly comprises bacillus subtilis, bacillus coagulans and clostridium butyricum. Bacillus subtilis and the like rapidly grow and breed after entering the digestive tracts of livestock and poultry in a spore state, consume oxygen in intestinal tracts, cause an anaerobic environment in the intestines, promote the growth of anaerobic bacteria and further restore the microecological balance among microorganisms in the intestines. Can synthesize various vitamins and can also produce various digestive enzymes, thereby improving the feed conversion rate; it also has the function of promoting appetite of animals. The bacillus coagulans is one of lactic acid bacteria, can decompose saccharides to generate L-lactic acid, and the generated L-lactic acid can reduce the pH value of intestinal tracts, inhibit harmful bacteria and promote the growth and reproduction of beneficial bacteria such as bifidobacteria and the like. The lactic acid produced by the lactic acid can also promote the absorption and utilization of iron, phosphorus, calcium, vitamin D and the like by animal organisms. The clostridium butyricum is an anaerobic bacterium and can be planted in the rear intestinal tract, the clostridium butyricum can ferment and hydrolyze starch and saccharides, the final metabolite is mainly butyric acid, the butyric acid is the optimal energy substance of intestinal villus and is a main nutrient substance for repairing and regenerating intestinal epithelial cells, and the clostridium butyricum has important significance for regenerating and repairing intestinal epithelial tissues, can promote the development of the intestinal tracts of livestock and poultry and strengthen various functions of the intestinal tracts; the clostridium butyricum has good curative effect on symptoms such as acute and chronic diarrhea, intestinal stress syndrome, antibiotic-associated enteritis, constipation and the like caused by dysbacteriosis, and particularly has unique effect on pseudomembranous enteritis caused by applying antibiotics. The strain can also promote the absorption of vitamin E, degrade cholic acid and improve antioxidant ability.
Vitamin E (VE), also known as Tocopherol, is a generic term for all tocopherols and tocotrienols and derivatives thereof with α -Tocopherol (a-Tocopherol) activity, which plays an important role in the anti-free radical and heme synthesis (Chen, 1996), and also participates in the immune response and gene regulation of the body (Bendich, 1986; Wuryastuti et al, 1993). vitamin E is a vitamin which is studied more and has a significant improvement effect on meat quality.
In a second aspect, the invention provides a feeding method for improving the growth performance of fattening pigs, which comprises the following steps:
step 1, feeding the suckling pigs for 5-6 times every day by adopting suckling pig feed every day, wherein 300-400 g of the suckling pigs are fed every day from the weaning day of the suckling pigs to one month;
step 2, feeding the piglets for 1-3 months for 3-4 times every day by adopting piglet feed, wherein each time is 2-4 kg;
step 3, feeding the piglets for 2-3 times every day by adopting the feed when the piglets grow to 80kg, and feeding 5-6 kg each time; continuously feeding for 7 months;
pigsty management: controlling the temperature of the pigsty to be 15-20 ℃ and the relative humidity to be 40-70%; the cultivation density is 1.3-1.5 m2A/head; periodically cleaning urine and excrement, ventilating in time, and disinfecting the pigsty with a disinfectant after cleaning the pigsty;
disease prevention and control: the medicine for preventing swine dysentery is ground regularly and mixed with drinking water for pigs to feed the pigs, so as to prevent swine dysentery.
Further, the suckling pig feed comprises the following components in parts by weight: 50 parts of whole milk powder, 50 parts of cooked eggs, 1 part of yeast, 5 parts of lard, 50 parts of glucose, 5 parts of inorganic salt solution, 5 parts of vitamin solution and 200 parts of milk.
