Description
Technical field
The present invention relates to a kind of low fast well-fattened methods of nitrogen daily ration of Laiwu Black Pigs.
Background technique
Currently, the fast development with aquaculture to large-scale, standardized direction, professional raiser raises Laiwu Black Pigs
Scale is more and more big, and numerous raisers on the one hand will be by the production performance of raising Laiwu Black Pigs, on the other hand by reducing Lay
The aquaculture cost of overgrown with weeds black pig improves the economic benefit of aquaculture.But the disunity of feeding standard, the missing of amino acid profile, battalion
Feeding shortage makes the production performance of Laiwu Black Pigs be far from reaching its potentiality, it has also become restricts one of Laiwu Black Pigs industry development
Key factor.On the other hand traditional feed major part nutrition is unreasonable, and inconvenient to use, aquaculture cost is also high.Improve Laiwu
The physiological function and health status of black pig, economic benefit will be significantly improved by reducing aquaculture cost, and therefore, being badly in need of one kind can change
Kind Laiwu Black Pigs production performance and the fast well-fattened technology for reducing aquaculture cost simultaneously.
Above-mentioned traditional yard feeding pattern is technically existing insufficient, is mainly manifested in the following aspects: (1) Laiwu Black Pigs
Growth cycle is long, and the Laiwu Black Pigs of numerous raisers' raising are averaged marketing time at 12 months or more；(2) Laiwu Black Pigs deliver body for sale
Weight is low, and averagely delivering weight for sale is 86kg；(3) Laiwu Black Pigs feed-weight ratio is high, and entire growth cycle feed-weight ratio is 4.2.
The history raising of Laiwu Black Pigs can at least trace back to Neolithic age primitive society.In the fifties in last century
Before, purebred Laiwu Black Pigs are commonplace in Laiwu locality.From the end of the fifties in last century to the mid-1970s, introduce to no plan
New product boar and Laiwu Black Pigs crossbreeding and improvement, purebred Laiwu Pigs are constantly eliminated.To the end of the seventies in last century, purebred Laiwu Black Pigs
It is on the verge of impasse.For Laiwu Pigs the disadvantage is that fattening capacity and carcass characteristic are slightly worse, weight gain is slow, and in body maturation evening, the price of deed is low, skin depth,
Fat thickness, eye muscle area and dressing percentge are small, and lean meat percentage is low.The feed mode for how improving Laiwu Black Pigs, there is presently no unified
Standard, it is fast well-fattened that purebred Laiwu Black Pigs are not suitable for the feed mode of hybridization black pigs.
Summary of the invention
The purpose of the present invention is to solve the above-mentioned problems, provides a kind of Laiwu Black Pigs the low fast well-fattened side of nitrogen daily ration
Method improves the production performance of Laiwu Black Pigs, effectively facilitates the growth of pig, improves the digestibility and utilization of feed, improves the healthy shape of pig
Condition and organism physiology function.
To achieve the goals above, the present invention adopts the following technical scheme:
A kind of low fast well-fattened method of nitrogen daily ration of Laiwu Black Pigs, (1) grows Laiwu Black Pigs according to the weight of Laiwu Black Pigs
Development is divided into three periods, is child care phase: 15-30kg, growth period: 30-60kg, fattening period: 60-90kg respectively；(2) according to not
Amino acid profile is arranged in same period, is the child care phase respectively: lysine in diet: methionine: methionine+cystine: threonine:
Tryptophan=100: 27: 54: 59: 16, growth period: lysine: methionine: methionine+cystine: threonine: tryptophan=100
: 24: 48: 52: 14, fattening period: lysine in diet: methionine: methionine+cystine: threonine: tryptophan=100: 21:
42:46:13；(3) by the Proportionality design formula between amino acid in model described in step (2), daily ration is configured, is fed stage by stage
?.
The daily ration refers to the mixing of corn, wheat-middlings, dregs of beans, corn DDGS and soybean oil.
It is preferred that: the mass ratio between above-mentioned each raw material of daily ration is as follows: corn: wheat-middlings: dregs of beans: corn DDGS: soybean oil
=(55-65): (5-15): (10-22): (5-10): (1-2).
More preferable: the mass ratio between child care phase each raw material of daily ration is as follows: corn: wheat-middlings: dregs of beans: corn DDGS: big
Soya-bean oil=59:10:17:8:1.6.
Mass ratio between each raw material of growth period daily ration is as follows: corn: wheat-middlings: dregs of beans: corn DDGS: soybean oil=
59:13:14:8:1.55。
Mass ratio between each raw material of fattening period daily ration is as follows: corn: wheat-middlings: dregs of beans: corn DDGS: soybean oil=
59:16.5:11:8:1.5。
The utility model has the advantages that
Fattening method design principle of the invention: first according to the growth and development characteristics of Laiwu Black Pigs, by Laiwu Black Pigs point
It is right to the difference of feed nutrition and between each period for each period Laiwu Black Pigs for child care phase, growth period and fattening period
The connection and relationship of amino acid requirement, the speed of growth in order to reach pig is fast, the period is short, delivers for sale and increases again, and feed-weight ratio is low etc. asks
Topic, devises Laiwu Black Pigs 15kg to the required amino acid profile with conspiracy relation delivered for sale, and provides making for science
Use scheme.
Amino acid pattern of the invention is paid special attention to meet the amino in black swine rations while paying close attention to amino acid balance
Sour requirement effectively facilitates the growth and development of black pig, improves the health status of black pig, improves the immunity of pig, increases the food of pig
It is intended to, improves the weight gain of black pig, and improve the speed of growth of pig body physiological function and later period and the digestibility and utilization of feed.
Using this product, black growth speed of pigs is fast, and the period is short, delivers for sale and increases again, and feed-weight ratio is low, and the price of deed is low.
Specifically introduce the effect of various amino acid in model:
Lysine is a kind of basic amino acid, is synthesis cranial nerve, life as the first limiting amino acids in swine rations
The necessary material of cell colonization nucleoprotein and hemoglobin can promote the absorption of arginine and calcium, has enhancing pig appetite, improves
The effects of healing of premunition and promotion wound, fracture and suppuration sore, the meat of pig can also be improved, improve lean meat percentage.
Methionine is a kind of methyl donor, is shifted by methyl, participates in the synthesis of adrenaline, choline and creatine, is pig
The second limiting amino acid in daily ration, in adipose metabolism, methionine participates in the synthesis of lipoprotein, and fat is exported liver
Outside, it prevents fatty liver, reduces cholesterol, methionine can promote to develop, and increase daily gain.
Tryptophan is the third limiting amino acid in swine rations, participates in the update of plasma protein, and with hemoglobin, cigarette
The synthesis of acid is related, it can promote vitamin B2The performance of effect, and the transfer function with nerve impulse are piglet growth hairs
It educates and amino acid necessary to Adult Pig breeding, lactation.
Threonine is the 4th limiting amino acid in swine rations, can adjust amino acid balance in feed, promotes growth, changes
Kind meat, the nutritive value for improving the low feedstuff of amino acid digestibility, save protein resource, can reduce feedstuff at
Originally, the nitrogen content in swine excrement and urine, ammonia concentration and rate of release in pig house are reduced.
Cystine can promote cell Redox function, keep liver function vigorous, and can neutralize a toxin, leucocyte is promoted to increase
Raw, prevention pathogen develops.
Specific embodiment
Below with reference to embodiment, the invention will be further described.
Embodiment 1
In order to verify amino acid profile of the invention to the feeding effect of Laiwu Black Pigs, technology department of applicant company is in 2014
April in year has carried out feeding experiment in Animal Science And Technology experiment station of Shandong Agricultural University.Test is set using single factor test comparative test
