Preferably, the feeding period of the folic acid is from breeding is started to lambing.
Preferably, the feed mode of the folic acid is after being mixed with daily ration, and each feeding is primary sooner or later.
Preferably, the dam is sheep.
Preferably, it is directed to sheep kind, present applicant proposes specific feed mode, the folic acid is coating folic acid,
The additive amount of the folic acid is that 15~17mg is added in every kilogram of diet dry substance, and feeding period of the folic acid is from starting to match
Kind is to lambing, and feed mode is after being mixed with daily ration, and each feeding sooner or later is once.
It is furthermore preferred that the additive amount of the folic acid is to add 16mg in every kilogram of diet dry substance.
The method of the present invention has the advantages that：
1) method of the invention can effectively improve the lambing percentage of dam, the ratio of three lambs of production especially can be improved, this is right
It has very important significance in the mass propagation of sheep.
2) method of the invention may additionally facilitate the birth weight of lamb, ensure survival rate and the healthy growth of lamb.
3) method using the present invention feeds dam, can also improve ewe postpartum body condition, promotes Recovery, Jin Erbao
Demonstrate,prove the healthy growth of lamb.And the method for the present invention simple operation, remarkable in economical benefits.
Specific implementation mode
The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention..
It is illustrated by taking sheep as an example in embodiment, but applicant tests and finds, other kinds of sheep can also obtain class
As effect.
Embodiment 1
This example illustrates the method for the present invention using pregnant dam as research object.
It is close, healthy through producing heat sheep dam 120 to be matched to choose same strain, weight, and is completed in three days
Breeding work (is respectively matched primary) sooner or later, and breeding is randomly divided into 3 groups, respectively control group, experimental group 1 and experimental group immediately after the completion
2, the daily ration of the additional addition different level folic acid of feeding, maintains each processing feed intake identical, specifically as shown in table 1 respectively.
The different group daily rations of table 1 add folate level
Remarks：DMI is dry matter intake in table 1.
It after the completion of breeding, is fed according to processing, 16-18 ages in days carry out trying anti-feelings, reject non-pregnant female；With finishing
Cheng Hou, 30 ages in days further detect breeding as a result, rejecting non-pregnant female again according to B ultrasound testing result using B ultrasound, finally produce
The dam number of lamb is 85 control groups 26, tests 1 group 32, tests 2 groups 26.The lamb of different disposal is counted after offspring born
The lambing situation of sheep, the lambing sum of the lambs of difference group and weighing for lamb and dam, because through producing dam with two lambs and three
Based on lamb, therefore single lamb and four lambs are not included in weight Information Statistics.Dam lambing is weighed after 24 hours.
The dam lambing situation of 2 control group of table and experimental group
As can be seen from Table 2, the number for testing two lambs in 1 group and 2 groups is decreased obviously, and the number of three lambs obviously increases, this
It proves in the daily ration of dam after addition folic acid, producing three lambs to dam significantly facilitates effect.
1 group of lambing percentage Chi-square Test result of 3. control group of table and experiment
1 group of lambing percentage Chi-square Test result of 4. control group of table and experiment
Table 5. tests 1 group and 2 groups of lambing percentage Chi-square Test results of experiment
Table 3, table 4 and table 5 are the comparisons of control group and experimental group lambing percentage, the experimental results showed that, gestational period dam daily ration
Middle addition 16 and 32mg/kg.DMI folic acid can significantly improve lambing percentage, and add 16 and 32mg/kg.DMI folic acid, two experiments
Significant difference is had no between group.Control group lambing percentage is 218.52%, and 1 group of experiment is 237.50%, tests 2 group 219.23%.
18.98% is improved compared to 1 group of lambing percentage of experiment compared with control group, and tests 2 groups and only improves 0.71%.Wherein, it is compared compared with control group,
It tests 1 group and 2 groups of twin lamb(s) lambing percentages of experiment is not decline 18.63% and 20.80%, and three lamb lambing percentages, 25.23% He of increase
16.10%；The lambing percentage of single lamb and four lambs, 1 group of experiment declines 6.60% compared with control group, and tests 2 groups of raisings 4.70%.
Table 6. produces two lambs and three lamb dam weight and lamb Birth weight dual factors the result of multiple comparisons
Remarks：First starting weight is dam weight before breeding, and postpartum weight is that postpartum, dam weight, net gain=postpartum weight-were antenatal for 24 hours
Weight, the relative weight gain=net gain/antenatal weight
Production twin lamb(s) or three lamb dam postpartum weight are simultaneously not affected by the influence that folic acid is added in daily ration, but produce twin lamb(s) dam postpartum
Weight is significantly higher than three lamb dams of production, and 1 group of the experiment that folic acid is added in daily ration is more right with 2 groups of net gains of experiment and the relative weight gain
It is dramatically increased according to group, respectively relative increase 41.01% and 37.42%, 41.14% and 35.56%；
Lamb Birth weight significantly improves (relative increase respectively also with 16 and 32mg/kg.DMI folic acid is added in daily ration
7.51% and 7.80%).Birth weight is without dramatically increasing wherein between each processing group of twin lamb(s), and three lambs test 1 group and 2 groups of bodies of experiment
It is significantly higher than control group again.
Therefore, Comprehensive Experiment is as a result, the effective coating folic acid for adding 16mg/kg.DMI in daily ration can be improved through producing dam
Lambing percentage and offspring born weight, and be conducive to postpartum dam recovery.
