Abstract

The invention discloses a pig feed formula. The pig feed comprises the following components by weight percent: 49-66.4% of corns, 8.5-12.3% of soybean meal, 8.5-12.3% of wheat bran, 2-7% of an additive and 5-30% of fermented corn straws, wherein the additive is composed of the following components: 42.5% of mountain flour, 20% of calcium hydride, 12.5% of table salt and 25% of a mineral substance and vitamin additive mixture. According to the pig feed disclosed by the invention, the fermented straws are used for replacing components in feed ingredients, so that the feeding cost of live pigs can be reduced, and the growth performance of the pigs, the feeding nutrient digestibility and the meat quality are effectively improved.

Description

A kind of formula for pig forage

Technical field

The invention belongs to pig cultural technique field, be specifically related to a kind of formula for pig forage.

Background technology

China first to raise pigs big country in the world, and be the second Feed Manufacturing big country in the world, wherein pig feed accounts for more than 40% of feed total amount, and feed industry occupies an important position in national economy.What cost maximum in pig industry was maximum is feed cost, almost account for 80% of Swine Production cost, in pig feed primary raw material, the consumption of corn and dregs of beans accounts for 60 ~ 70% of feed proportion, and the cost of corn and dregs of beans is higher, therefore corn and value of the meal produce directly impact to feed cost.How not affect on the basis of culture efficiency, adopting other materials Substitute For Partial corn and dregs of beans, thus reducing aquaculture cost, becoming feed factory problems faced.In addition, therefore develop a kind of pure natural feedstuff, be not only rich in all kinds of nutriment needed for domestic animal growth but also do not needed the additive of any Prof. Du Yucang, made domestic animal getting fat rapid, shorten growth cycle, become the common expectation of feedstuff industry with the feed improving production value.

Summary of the invention

The object of the invention is, for the high problem of pig feed aquaculture cost, to provide a kind of formula for pig forage, it, while the nutritional need ensureing pig growth, reduces feed cost, for raiser improves maximum cultivation interests.

The present invention realizes especially by following technical scheme:

A kind of formula for pig forage, weight percentage comprises following component:

Corn 49 ~ 66.4%, dregs of beans 8.5 ~ 12.3%, wheat bran 8.5 ~ 12.3%, additive 2 ~ 7%, fermented maize stalk 5 ~ 30%.

Preferably, a kind of formula for pig forage, weight percentage comprises following component: corn 63%, dregs of beans 11.5%, wheat bran 11.5%, additive 4%, fermented maize stalk 10%.

Additive of the present invention is composed of the following components: 42.5% stone flour, 20% hydrogen calcium, 12.5% salt, 25% minerals and vitamins additive agent mixture.

Beneficial effect of the present invention is: utilize stalk resource, reduces the environmental pollution of burning and causing; Utilize fermented stalk to substitute component in feed ingredient, the feeding cost of live pig can be reduced; Effectively can improve pig growth performance, raise nutrient digestibility, meat quality.

As shown in Table 4, in experiment pig meat, comprise yellowish pink, marbling, cold cuts rate, dehydration power and tenderness aspect, between experimental group and control group, there is not significant difference (P>0.05).

Embodiment 7 serum urea nitrogen content

Fermented stalk is on testing the impact of front middle and later periods serum urea nitrogen content in table 5, from table 5, by to three period serum urea nitrogen content variance analysis, only have test fermented stalk alternate sets in mid-term 30% and 20% fermented stalk alternate sets significant difference (p<0.05), the difference between all the other each group is not all significantly (p>0.05).

Table 5 serum urea nitrogen content

Embodiment 8 feed nutrition digestibility

1) digestibility of test pig energy in early stage, protein and fiber is in table 6.

Table 6 nutritive digestibility in early stage

From table 6, test the equal significant difference of digestibility (p<0.05) of each group of energy.In the digestibility of protein, only have 15% to substitute and 30% alternative difference remarkable (p>0.05), all the other respectively organize equal significant difference (p<0.05).In digestibility of fiber, each test group and control group significant difference (p<0.05), wherein 10%, 15% and 20% alternate sets difference is not significantly (p<0.05).

2) digestibility of pig energy in mid-term, protein and fiber is tested in table 7.From table 7, test the equal significant difference of digestibility (p<0.05) of each group of energy.In the digestibility of protein, 20% is only had to substitute and 30% alternative difference remarkable (p>0.05).All the other are the equal significant difference of group (p<0.05) respectively.In digestibility of fiber, each test group and control group significant difference (p<0.05), wherein 15% and 20% alternate sets difference is not significantly (p>0.05).

Table 7 nutritive digestibility in mid-term

3) digestibility of later stage pig energy, protein and fiber is in table 8.

Table 8 later stage nutritive digestibility

From table 8, test the equal significant difference of digestibility (p<0.05) of each group of energy, protein and fiber.

To sum up, in all periods, each test, along with improving constantly of maize straw adding proportion, the digestibility of the energy of feed, protein and fiber is all on a declining curve, and the addition of 20% and 30% seriously have impact on the digestibility of test daily ration Main Nutrients.

Embodiment 9 Economic and Efficiency Analysis

Table 9 test pig feed cost benefit

Note: every pig profit=end weight × unit price-cost+experimental stage feedstuff for live pigs cost of every pig (during the 60kg), wherein pork price be 15.6 yuan/kg, 60kg time every pig cost by 1000 yuan.

From table 9, when growing and fattening pigs reach deliver body weight for sale time, according to market conditions at that time, adding maize straw can increase economic efficiency, but when reaching 15%, compared with control group, has just occurred loss phenomenon.Add maize straw in test daily ration and can reduce feeding cost to some extent.Wherein, wherein the biggest drop is the addition of 10% maize straw, reaches relative cost 12.45%.In 30% interpolation group, feeding cost is also decline, but the comprehensive factor such as daily gain, feed nutrient digestibility, its using value is still needed and will be studied further and assess.
