Embodiment 1 pyrrolidine hydrochloride row ketone is to INFLUENCE OF YUCCA EXTRACT
In order to observe the effect of pyrrolidine hydrochloride row ketone, carried out feeding experiment twice respectively on November 22nd, 2007 to December 20 and on May 5th, 2009 to June 13 planting the pig farm in Zengcheng City, Guangdong Province Agricultural University Of South China as feed addictive.The pig of twice test is all for greatly enhancing the assorted pig of binary, and the test pig beginning average weight of all rising is 54 kilograms for the first time, it raised stage definitions be fattening early stage; The initial average weight of swinery is 70 kilograms for the second time, it is raised stage definitions be the fattening middle and later periods.
Test is adjusted swinery the phase of raising in advance, and a hurdle i.e. a repeating groups, every hurdle (repetition) 8 pigs, and totally 10 hurdles (repetition), test group and control group have five repetitions respectively, guarantee that as far as possible the existing test group of each part of animal house has control group again.Control group fed pig farm basal feed, test group add the pyrrolidine hydrochloride row ketone of 80mg/kg on the basis of pig farm basal feed, the record swinery search for food and the serum index (table 1 ~ 2) of swinery is measured in weightening finish situation and blood sampling.
Table 1 pyrrolidine hydrochloride row ketone is to the influence of fattening pig (50-70kg) growth performance in early stage
Figure GSB00000271291700051
Table 2 pyrrolidine hydrochloride row ketone is to the influence of fattening pig middle and later periods (70-90kg) growth performance
Figure GSB00000271291700052
1, to the influence of average daily gain
The first time tests the average daily gain test group and control group is more or less the same, and the weightening finish of 0 ~ 14d control group is high slightly, and the weightening finish of 14 ~ 28d test group is high slightly, and the full phase, test group is identical with the control group average daily gain; It is high by 6.72% to test for the second time full phase average daily gain test group contrast control group, and the average daily gain of each step-by-step test group all is higher than control group.The result shows that pyrrolidine hydrochloride row ketone does not influence the average daily gain of fattening pig in early stage, but can improve fattening phase middle and later periods pig average daily gain 51g/d.
2, to the influence of average daily ingestion amount
Testing for the first time average each stage of daily ingestion amount test group all will be lower than control group, and the average daily ingestion amount significant difference (P<0.05) of full phase.The second time tests average daily ingestion amount test group of full phase and control group is more or less the same, and the daily ingestion amount of 0 ~ 14d control group is high slightly, and the daily ingestion amount of 14 ~ 28d test group is high slightly.The result shows that pyrrolidine hydrochloride row ketone can reduce the average daily ingestion amount 120.9g/d of fattening pig in early stage, but does not influence the average daily ingestion amount of fattening middle and later periods pig.
3, reduce the material anharmonic ratio
Test for the first time full phase material anharmonic ratio test group contrast control group and reduced by 5.13%; And the material anharmonic ratio test group in each stage all will be lower than control group, and having reduced the material anharmonic ratio under the situation of be more or less the same in weightening finish (differing 0.04%) mainly is because feed intake has descended.Test for the second time full phase material anharmonic ratio test group contrast control group and reduced by 5.52%.The result shows, from the whole fattening pig stage, adds pyrrolidine hydrochloride row ketone in the feed for reducing the material anharmonic ratio, and it is very resultful reducing feed cost.Though the fattening pig has all reduced more than 5% with fattening phase middle and later periods material anharmonic ratio early stage, there is notable difference in its mechanism of action, and fattening pig is because under the prerequisite that does not influence weightening finish in earlier stage, reduces food consumption and causes; The fattening pig middle and later periods is owing under the prerequisite that influences food consumption hardly, improve daily gain and realize.
Test shows, adds PIOGITAZONE HYDROCHLORIDE in the grow-finish pig feed, can improve the growth performance of pig, reduces the feed cost of per gain weight, promotes the healthy growth of swinery.
Embodiment 2 influences the serum biochemistry mechanism of production performance
For the serum glycolipid metabolism of observing pig and pig utilization rate to protein; The pig of choosing about average weight is individual; Each repeats to select 2 (each 10 of control group and test group), carries out the vena cava anterior blood drawing, centrifugation serum; Each item serum index is measured, comprised blood sugar, triglycerides, serum urea nitrogen and The Total albumen content (table 3 ~ 4).
Table 3 pyrrolidine hydrochloride row ketone is to the influence of fattening pig serum biochemistry index in early stage
Figure GSB00000271291700071
Table 4 pyrrolidine hydrochloride row ketone is to the influence of fattening pig middle and later periods serum biochemistry index
Blood-sugar content and lipids contents test group and the control group of testing for the first time 14d, 28d all are more or less the same; And all be within the normal range (NR); The serum urea nitrogen control group all was higher than test group in 14d and 28d days; The serum urea nitrogen of 14d test group is lower by 34.45% than control group, and the serum urea nitrogen of 28d test group is than control group low 31.35%.This explanation pyrrolidine hydrochloride row ketone is all little to the glycolipid metabolism influence of the individual serum of healthy animal; But protein metabolism has been produced certain influence; The utilization rate of the decline explanation protein of serum urea nitrogen raises; This is consistent with the growth data result of front, infers that the synthetic increase of protein possibly be that the pig feed intake reduction does not but reduce the big main cause of average daily gain before the stage of fattening.
Blood-sugar content, serum urea nitrogen content test group and the control group of testing for the second time 14d, 28d all differ not quite, and the test group lipids contents is higher by 10% than control group, and blood sugar and lipids contents all are in the normal range (NR), are more or less the same on the whole.According to testing result, infer that pyrrolidine hydrochloride row ketone is little to serum glycometabolism and the protein utilization influence of fattening pig middle and later periods, possibly influence its fat metabolism.
This is very different with treatment diabetes clinical test results; The clinical research result shows; The type-II diabetes patient blood sugar and the lipids contents of taking pyrrolidine hydrochloride row ketone have all obtained tangible decline, and this result of the test shows that pyrrolidine hydrochloride row ketone produces obvious influence hardly to the animal individual blood sugar and the lipids contents of normal physiological status.
Embodiment 3 pyrrolidine hydrochloride row ketone are to the influence of meat quality and possible mechanism thereof
For the further influence of observing pyrrolidine hydrochloride row ketone additive to meat quality, and inquire into its possible mechanism of action.On June 28th, 2009; When for the second time feeding experiment finishes, select to be in 10 of pigs about average weight, each repeats one (respectively 5 of test group and control groups); Guangdong Province's herding in meat matter evaluation slaughter line carry out slaughter experiment, measure its carcass trait and meat matter proterties; And carrying out the sample collection, research pyrrolidine hydrochloride row ketone influences the mechanism of meat matter.
Table 5 pyrrolidine hydrochloride row ketone is to the influence of fattening pig middle and later periods carcass trait and meat matter
Figure GSB00000271291700091
1, to the influence of carcass trait
The test group thickness of backfat reduces by 5.07% than control group; The dressing percentage of test group is higher by 1.21% than control group.That is to say that pyrrolidine hydrochloride row ketone can reduce the thickness of backfat (relevant with lean meat percentage) and increase dressing percentage.
2, improve meat matter
In several indexs of definition meat matter, the drip loss of test group meat sample, yellowish pink scoring and marble grain scoring all are better than control group, and the drip loss test group is than control group low 11.03%.All within normal yellowish pink scope, the test group mark is higher by 7.89% than control group for yellowish pink scoring test group and control group; With chromascope to yellowish pink a value measure; A value and b/a value are all represented yellowish pink scarlet degree, are also representing intramuscular pigment content, and a value is directly proportional with yellowish pink scarlet degree; And the b/a value is inversely proportional to yellowish pink scarlet degree; The a value of test group is higher by 6.42% than control group, and the b/a value of test group is littler by 10.00% than the b/a value of control group, and this explanation test group meat appearance color has scarlet trend.What the marble grain scoring was showed is the content of fat between intramuscular fat and flesh; The marbled degree of depth and intramuscular fat are proportionate; Kind is careful more; The ratio of invisible intramuscular fat is big more in the more high-grade pork of meat, and is higher by 32.18% than control group through the marble grain scoring of qualification test group.These data show that test group meat sample matter is better than control group.Again test group and control group longissimus dorsi muscle slaughter meat appearance have been carried out intramuscular fat mensuration subsequently; The result is that the intramuscular fat content of test group longissimus dorsi muscle exceeds control group 17%; Intramuscular fat content has the trend of obvious increase, matches with the marble grain appraisal result.Comprehensive drip loss, yellowish pink, marble grain, intramuscular fat content etc. influence the index of meat merit, add pyrrolidine hydrochloride row ketone in the feed meat tool is improved significantly.
Embodiment 4 pyrrolidine hydrochloride row ketone are to the influence of glycolipid metabolism in the muscle
GLUT4 is the glucose transport factor 4; Mainly be present in the muscle; The effect of its expression is the transhipment of participating in glucose in the body; One of insulin resistance characteristic of diabetes B patient is exactly expression and the transposition obstacle of GLUT4, and clinical testing shows that the expression of the patient GLUT4 that has taken pyrrolidine hydrochloride row ketone obviously increases; FABP3 is a fatty acid binding protein, participates in the transportation of aliphatic acid, is the important factor of fat deposition.
Increase the molecular mechanism of intramuscular fat content for further studying pyrrolidine hydrochloride row ketone; RNA to pig longissimus dorsi muscle sample has carried out extracting; Reverse transcription becomes cDNA; As internal standard gene, GLUT4 gene and FABP3 gene are carried out real-time fluorescence quantitative RT-PCR mensuration with GADPH, observe their relative expression quantity.The result shows (Fig. 1), and the FABP3 that participates in fat transfer expresses obviously and increases, and the relative expression quantity of the FABP3 gene of test group is higher by 65.12% than control group; And the relative expression quantity test group and the control group of participating in the GLUT4 of musculature glucose transport are more or less the same.Prompting pyrrolidine hydrochloride row ketone maybe be through increasing the expression of FABP3, thereby increase the synthetic of aliphatic acid in the muscle, finally shows as the raising intramuscular fat content, increases marble grain.And pyrrolidine hydrochloride row ketone is expressed influence not quite to muscle glucose transport carrier GLUT4, in conjunction with serological index, can judge that basically pyrrolidine hydrochloride row ketone does not have influence basically to the individual glycometabolism of health pig.
Embodiment 5 oil red O stain frozen sections are observed the general distribution situation of intramuscular fat
For the superficial appearance of viewing test group and control group intramuscular fat, the longissimus dorsi muscle sample of gathering has been processed frozen section, and frozen section has been carried out oil red O stain.Oil red O stain is a kind of colouring method that fat is identified, dyestuff mainly is oil red and haematoxylin.At first section is dyeed, the fat in the sample is dyed redness, use the nuclear staining of haematoxylin pair cell again, make the monoblock section be easier to observe, the fat of being dyed redness that microscopically is mainly observed with oil red.That Fig. 2 shows is test group and the representational oil red stained of control group pig longissimus dorsi muscle figure (100 *); From figure, can see; The fatty oil droplet that is colored in the test group muscle samples longer thicker (redness); Area occupied is bigger, and this can be from the situation of side reflection test group intramuscular fat content increase.
