Abstract

The invention discloses a preparation method of sweet elephant grass Luchuan sow feeds, which belongs to the technical field of feed processing and is characterized by comprising the following raw material components of 350-550 parts of pressed whole sweet elephant grass, 700 parts of 600-shaped corn flour and 5-10 parts of premix.

Description

Method for preparing sweet elephant grass Luchuan sow feed

Technical Field

The invention belongs to the technical field of feed processing, and relates to a preparation method of sweet elephant grass Luchuan sow feeds.

Background

The feed is a material basis for pig raising, the expense of the feed accounts for more than 75-80% of the cost of pig raising, particularly, a daily ration mode of 'corn and soybean meal' is commonly adopted for pig raising in south China, the feed is short in raw material source and serious in environmental pollution, so that the use amount of protein raw materials such as soybean meal and the like in pig feed is reduced, the development of grain-saving ecological pig raising is promoted, the feed is a main development direction of pig raising in China, the sweet elephant grass is a high-quality protein feed resource which is low in planting cost, high in yield and perennial, the sweet elephant grass crude protein is 4.93%, the crude fat is 1.06%, the nitrogen-free extract is 4.57%, the calcium is 0.075%, and the phosphorus is 0.07%, the crude protein and the crude fat are 3 times higher than the content of local weeds, under good cultivation management, the -time planting of the perennial sweet elephant grass can be utilized for 4-5 years, the feed can be harvested for many times, the fresh grass can be produced per mu, 3000-7500 kg, the sweet elephant grass is rich in nutrition, the pig raising can be used for replacing the pig raising or partially replacing the pig, the development of the feed, the pig raising industry, the social development of the soybean meal is accelerated, the social development of the modern pig raising industry is realized, the social pollution of the national food is reduced, the growth of the pig raising industry is reduced, the environment is reduced, the development of the national food is reduced, the growth.

Disclosure of Invention

The invention aims to develop sweet grassiness pig feeds which are economical, grain-saving and ecological and environment-friendly, aiming at the problems of high feed cost and serious excrement environmental pollution caused by a corn and soybean meal daily ration mode commonly adopted by pigs raised in south China at present.

In order to achieve the purpose, the invention adopts the following technical scheme:

the preparation method of the sweet elephant grass Luchuan sow feed comprises the following raw material components, by weight, 350-550 parts of pressed whole sweet elephant grass, 600-700 parts of corn flour and 1-5 parts of premix.

Preferably, the feed comprises the following raw material components in parts by weight: 370 parts of briquetting Taiwan sweet elephant, 600 parts of corn flour and 3 parts of premix.

Preferably, the moisture content of the pressed sweet elephant grass ranges from 55 to 70 percent.

Preferably, the weight parts of the raw materials include 200 g of ferrous sulfate, 100 g of copper sulfate, 200 g of zinc sulfate and 3000 g of calcium carbonate. The inorganic salts are weighed out accurately. Levigating, mixing in daily ration of sweet grassiness and corn, expanding gradually to ensure the mixing uniformity, and the formula is used for 1 ton of daily ration of sow.

A preparation method of the sweet elephant grass Luchuan sow feed comprises the following steps:

(1) sweet elephant grass Luchuan sow feed is pretreated and briquetted, wherein the harvested fresh sweet elephant grass is rubbed and crushed, and is aired to adjust the moisture content of Taiwan sweet elephant to be within the range of 55-70% to obtain pretreated sweet elephant grass powder, and then the pretreated sweet elephant grass is compacted into a square-shaped sealed package by a hydraulic binder for later use, so as to be stored, transported and used;

(2) preparing a premix preparation: weighing the raw materials such as various mineral substances, lysine, phytase and the like in parts by weight, and then uniformly mixing to obtain a premix preparation;

(3) preparing corn flour: crushing the dried corns by a crusher (the diameter of a sieve sheet is 2.0-3.0 mm), and then bagging and storing for later use.

(4) Mixing and feeding, namely mixing the premix preparation in parts by weight, the corn flour in parts by weight and the pressed sweet grassiness in parts by weight to prepare sweet grassiness pig feeds which can be immediately fed or bagged for 3-7 days for feeding.

Compared with the prior art, the invention has the following beneficial effects:

the cost of the feed is reduced. The production method of the grain-saving sweet grassiness pig feed adopts the pressed sweet grassiness to replace protein raw materials such as soybean meal and the like in daily ration, so that the average weight gain of the fed medium-sized and large-sized pigs per kilogram can be reduced by more than 1 yuan, and the economic benefit of pig raising is obviously improved.

And the grain is saved. The method for raising the pigs by adopting the pressed sweet elephant grass pig feed can fully utilize local resources to plant the sweet elephant grass to develop grain-saving pig raising, convert the sweet elephant grass into grains, save the grains and effectively relieve the contradiction of serious shortage of protein feed resources in pig raising in China at present.

Is ecological and environment-friendly. Can realize an ecological cycle breeding mode of planting and breeding combination, reduce the pollution of pig manure to air, water, soil and the like, and purify the environment.

The meat quality is improved, and the pork pig can reduce the content of cholesterol and low-density lipoprotein in the pork by feeding the sweet elephant grass daily ration for a long time, thereby being beneficial to producing high-quality high-grade green ecological organic pork.

Claims
