Description
Technical field
The invention belongs to livestock feed technical field, particularly a kind of feed addictive and application thereof containing brassin.
Background technology
At present, for the raising of poultry or livestock, commonly use the growth that some feed addictives promote them, especially after the dietary structure adjustment of current people, also more and more higher to the requirement of livestock or poultry, wish that raising the speed of growth accelerates, but reduce their fat content again simultaneously.Therefore, feed addictive just seems extremely important.But existing feed addictive major part only can make these poultry or livestocks grow to be accelerated, and can not control the fat that increases in its growth course.Meanwhile, about the product of " clenbuterol hydrochloride " also occurs, but this product is a kind of harmful substance, if for feed addictive, will produce the mankind because of tragedy dead after food meat.On the other hand, some feed addictive is a class antibiotic kind, equally also can damage the mankind.Thus, research can growth promoting effects, and the feed addictive not increasing again fat has become the problem paid close attention to.
Brassin is a kind of sterols plant hormone, is extracted and refines out from rape pollen, therefore also known as brassinosteroid or brassin lactones.Brassin lactones take sterol as the plant endogenous steroid physiological activator of skeleton, and it has strong facilitation to the elongation of axis and cell division.Be known as active the highest efficient, wide spectrum, nontoxic plant growth regulator in the world.Plant physiologist is thought, it fully can excite the inherent potential of plant, regulates and the growth promoting plant comprehensively, gives full play to growth vigor.
Brassinolide derives from rape pollen and beeswax, has very high health value, brings into use in medicine, health products at present.Be applied to good market prospects to be had in feed addictive.First, phytosterol energy growth regulation, promotes protein synthesis, improves the price of deed: secondly, phytosterol has raising lean meat percentage, and improve the quality of animal product, be conducive to human health: again, phytosterol has other physiological functions such as antioxidation activity.Can breeding performonce fo animals be improved, improve the economic benefit of cultivation.Finally, phytosterol has high security, has been successfully applied in food.
Summary of the invention
Goal of the invention: the above problem faced for China's aquaculture and feed industry, and the market demand of lean meat species food, the invention provides a kind of feed addictive containing brassin.Present invention also offers the application of above-mentioned feed addictive.

The result of use of brassin feed addictive provided by the invention is described below by concrete test example.
Test example 1 adopts the feed of additive containing brassin lactones of above-described embodiment 1, embodiment 2 to feed child care pig pilot run
1, materials and methods
1.1 experimental animals and method: length × plum child care stage pig amounts to 90.Separating tests 1 group, test 2 groups, control group.Establish three repetitions respectively for each group, each repetition 10, each group of basal diet is identical, test group adds the brassin feed addictive that the embodiment of the present invention 1 provides, test 1 group of every 100g embodiment 1 feed addictive mix fodder 1 ton, test 2 groups of every 200g embodiment 2 feed addictive mix fodders 1 ton, control group does not use feed addictive, free choice feeding and drinking-water.
1.2 feedings and managements: whole feeding process is fed by same poultry raiser, Manual material feeding, free choice feeding is freely drunk water, and each group all gives identical feeding and management and environmental condition, if test group pig is ill in process of the test, treats by former field therapeutic scheme.
1.3 observation index: start body weight, terminate body weight, feed intake, piggy appetite, off-test time child care head number.
2, result of the test
Table 1 adds the impact of brassin feed addictive on child care pig feed intake, daily gain, feed-weight ratio
Within experimental period: test 1 group of comparatively control group daily gain raising 20.0%, feed-weight ratio reduces 2.48%, and daily ingestion amount improves 17.03%.Test the comparatively control group raising 36.0% of 2 groups of daily gains, feed-weight ratio reduces 9.25%, and daily ingestion amount improves 23.42%.Test 2 groups of daily gains and comparatively test 1 group of raising 13.33%, feed-weight ratio reduces 6.94%, and daily ingestion amount improves 5.47%.
Test example 2 adopts the feed of additive containing brassin lactones of above-described embodiment 2, embodiment 3 to feed growing and fattening pigs effect
1, materials and methods
1.1 experimental animals and method: DLY three way cross, age in days is close, the later stage of about body weight 60kg fattens stage fattening pig 90, be divided into 3 process at random, each process 3 repetition, each repetition 10.Test 1 group of every 150g embodiment 2 feed addictive mix fodder 1 ton, test 2 groups of every 300g embodiment 2 feed addictive mix fodders 1 ton, control group does not add, free choice feeding and drinking-water.
1.2 feedings and managements: whole feeding process is fed by same poultry raiser, Manual material feeding, free choice feeding is freely drunk water, and each group all gives identical feeding and management and environmental condition.
1.3 observation indexs: on-test and at the end of, early morning weighs on an empty stomach.At the end of feeding experiment, every hurdle selects 2 pigs to butcher at random.Observation brassin additive is on the impact of the indexs such as pig growth performance, feed intake and carcass trait.
2, result of the test
The brassin additive of Different adding amount is on the impact of test pig daily gain, Bian appetite, feed-weight ratio
The brassin of table 2 Different adding amount is on the impact of Growth of Pigs performance
| Project | Average daily ingestion amount (kg/d) | Average daily gain (kg/d) | Feed-weight ratio |
| Control group | 2.13 | 0.69 | 3.08 |
| Test group 1 | 2.28 | 0.76 | 3.0 |
| Test group 2 | 2.30 | 0.79 | 2.91 |
Test pig daily gain and daily ingestion amount increasing and increase with brassin addition, feed-weight ratio increases with brassin addition and reduces.Test 1 group, test 2 groups and compare with control group, daily gain, Bian appetite significant difference (P < 0.05), test 2 groups of feed-weight ratio and compare significant difference (P < 0.05) with control group.
The brassin of table 3 Different adding amount is on the impact of fattening pig carcass trait
| Project | Dressing percentage/% | Lean meat percentage/% | The thickness of backfat/cm | Eye muscle area/cm 2 |
| Control group | 65.02 | 61.34 | 12.18 | 23.86 |
| Test 1 group | 68.54 | 62.51 | 11.22 | 28.62 |
| Test 2 groups | 68.35 | 64.38 | 9.63 | 29.04 |
Adding brassin to improve growing and fattening pigs dressing percentage, lean meat percentage, eye muscle area, reducing the thickness of backfat, testing 2 groups compared with control group, the thickness of backfat, lean meat percentage and eye muscle area significant difference (P < 0.05).
Illustrated by above test example, brassin feed addictive provided by the invention can significantly improve feed intake, daily gain, the lean meat percentage of pig, reduces feed-weight ratio and the thickness of backfat.
