Abstract
The invention discloses low-protein dietary premix and feed for a growing pig. The low-protein dietary premix for the growing pig is added with lysine, methionine, threonine, tryptophane, valine and other commodity amino acids so as to regulate the balance of amino acids in a crude-protein diet and improve the utilization ratio of a low-crude-protein diet; on the premise of improving the growth performance of the pig, the using amount of a protein raw material is reduced by 2-4%, the nitrogen emission in the livestock industry is reduced by 20-50%, and the pollution of the livestock industry to the environment is reduced. The feed for the growing pig references to the latest nutrition standard model for the growing pig, and designs the low-protein diet on the basis of an ideal amino acid model, so that the crude protein content of the formulated full-nutrition diet is reduced to 14.0-15.0%; and in combination with characteristics of local resources, a variety of feed for the growing pig, which use the low-protein dietary premix for the growing pig, are provided.
Description
Technical field
The present invention relates to feed addictive and feed, especially relate to a kind of for grower pigs low protein ration premix compound and feed.
Background technology
The develop rapidly of China's animal husbandry is that society provides the protein foods such as abundant meat, egg, milk, the living standard of people is significantly improved, China's pork total output 5,053 ten thousand tons in 2011, keep the first in the world pork output, meat occupancy volume has also exceeded the average level in the world per capita.
The fast development of farming industry causes severe contamination to environment, according to measuring and calculating, in pig industry, every pig on average produces fecaluria 2.5 tons per year, ten thousand pig farms environment defecation at least towards periphery just 30,000 tons every year on average, every daily blowdown water amount is 100 ~ 150 tons, and ight soil odor pollutant is up to kind more than 200; Secondly, also easily cause the generation of some epidemic disease of domestic animals diseases, harm humans is healthy.In addition, the fast development of animal husbandry causes feed resource critical shortage, particularly protein feed resource, China's feedstuff industry nearly 80% protein feeds raw material need from external import, estimate according to national grain and oil information centre, China's soybean yields in 2012 is 1,280 ten thousand tons, has created new low point since 1993, the price of soybean also continuous rise thereupon, annual import volume is increased sharply and is set a new record about 5,800 ten thousand tons.
At present, in pig's feed, major ingredient comprises corn, dregs of beans, wheat bran, rice bran etc., its ratio is up to 96% of pig's feed, on market, the pig common feature of premix product is added with lysine exactly, other amino acid add hardly as methionine, threonine, valine etc. or add on a small quantity, and fixed limiting amino acid has lysine, threonine, methionine and tryptophan in the conventional Diet Formula of pig.
Figueroa etc. (2002) show, when daily ration protein content reduces more than 3 percentage points, even if add above-mentioned four kinds of limiting amino acid (lysines, tryptophan, threonine and methionine), the speed of growth and the feedstuff-meat ratio of pig are also affected, because be subject to the restriction of other essential amino acid (see Figueroa J. L., A. J. Lewis, P. S. Miller, R. L. Fischer, R. S. G ó mez, and R. M. Diedrichsen, Nitrogen metabolism and growth performance of gilts fed standard corn-soybean meal diets or low-crude protein, amino acid-supplemented diets J ANIM SCI November 2002 80:2911-2919).
Figueroa etc. (2003) find further, and valine is the 5th limiting amino acid, and appropriate interpolation can improve the production performance of grower pigs significantly.(see Figueroa JL; Lewis AJ; Miller PS; Fischer RL; Diedrichsen RM.Growth, carcass traits, and plasma amino acid concentrations of gilts fed low-protein diets supplemented with amino acids including histidine; isoleucine, and valine. J Anim Sci. 2003 Jun; 81 (6): 1529-37.).
Russel etc. (1987) show, grower pigs is when feeding the low-protein diet of supplementary enough lysine, methionine, tryptophan and threonine, and valine is unique limiting amino acid.(see Russell, L. E., B. J. Kerr, and R. A. Easter. 1987. Limiting amino acids in an 11% crude protein corn-soybean meal diet for growing pigs. J. Anim. Sci. 65:1266-1272.) this result also convincingly demonstrated when supplementing enough four kinds of limiting amino acids in daily ration, and valine is the 5th limiting amino acid.Therefore, in low-protein diet the physiological function of valine and trophism always quite concerned in recent years.
CN 101485400 A discloses one and educates pig feed, compared with prior art, this invention has the advantage that amino acid ratio balances, dregs of beans use amount is few, save protein feed raw material, decrease antibiotic use, and by adding probiotic and complex enzyme, improving the gut flora balance of pig, thus improving pig health and the speed of growth.But only with the addition of lysine and methionine in this invention, do not add the limiting amino acid of other pig growth courses such as threonine, tryptophan, valine; When feeding pig, the soybean meal content in the major ingredient of pig's feed, also up to 21%, can not avoid the waste of crude protein in daily ration, does not also play the maximum capacity of " amino acid balance ".
In addition, by the impact of soybean protein raw material import restriction, domestic feeding cost remains high always, how to develop the focus that local protein resource and unconventional raw material have become researcher and the producer, especially in conjunction with low-protein diet, effective exploitation is carried out to the feeding raw material resources in locality and utilize the focus having become Animal husbandry production and scientific research personnel and paid close attention to.
For this reason, the present invention, in conjunction with local resources characteristic, according to grower pigs ideal amino acid profile and a large amount of research and production checking, proposes a kind of grower pigs low protein ration premix compound adding valine, and utilizes the grower pigs feed of local feeding raw material resources.
Summary of the invention

1.1.2, experimental program
Choose Du × length × large galt 240 of about 30Kg, be divided into test group, positive control group (low-protein diet does not add valine) and negative control group (high protein ration group), totally 3 process, each process 10 repetition (circle), each repetition 8 pigs.In the raising stage, it is 30 ~ 60kg that grower pigs raises the stage.The growth performance of test this stage swinery after terminating.
1.1.3, index determining
On-test and at the end of with repeats (circle) for unit empty stomach weigh, calculate the daily gain in each stage, daily ingestion amount and feedstuff-meat ratio.
1.1.4, result of the test
Note: above show the different letter representation significant difference (P<0.05) of same row mark, following table is same.
As can be seen from the above table, bear control group compare with the low albumen positive control group of not adding valine with high protein, the test group daily gain and the feed conversion rate that add valine significantly improve (P<0.05); And two control groups compare difference not significantly (P>0.05).The above results shows, the growth of interpolation to grower pigs of valine plays a driving role, and improves feed efficiency simultaneously, is conducive to reducing protein raw materials consumption further, and then reduces aquaculture cost, improves income of raising pigs.
