Resumo: |
This work aimed to study the effect of PGF2α administration on anestrous post-partum period in 80 goats, with continuos or controlled suckled, rised in semiextensive system with water and mineral salt ad libitum. The females, with age between two and six years, were randomly distributed in three groups (GI, GII e GIII). The females of GI (n = 30) received 250 μg of PGF2 α in vulvar muscle on days 6th and 12th after delivery. The females of GII (n = 30) received the treatment of Group I, but every day from days 6th to 10th after delivery. The GIII (n = 20) was the control group. The estrous detection was made by using teasers and the mating with bucks with confirmed fertility. The obtained data were analyzed by ANOVA and by analysis of standard errors of difference among proportions. Difference in the occurrence of estrous among the three experimental groups was not observed (P > 0,05), however the average time of post partum anestrous was not observed (P < 0,05) in animals treated with of post PGF2 α. It was also detected a relevant reduction (P > 0,05) of post-partum anestrous in females with controlled suckled. Difference was not registered (P > 0,05) on pregnant percentages among the different groups. It may be concluded that the administration of PGF2α in the beginning of puerperium in caprine is efficient to reduce the anestrous pos-partum period, specially in females controlled suckled; however do not influence the fertility in meat goats. In the second study the objective was to verify the viability of the PGF2α administration association or not with dexamethasone in the induction of birth in milk goats and its implication in the delivering of the afterbirth placenta,puerperal disturb and viability you create of them. This work was lead in the Pendencia Experimental Station, EMEPA, located at Soledade – PB. A total of 80 milk goats from different races had been used such as Anglo Nubian, Brown Alpine and British Alpine, presenting age between two and six years and gestational period between 143 and 146 days. Two experiments had been made, being experiment1 (n = 40) carried through in the dry period and experiment 2 (n = 40) carried through in the rainy period. The females had been randomly distributed in eight experimental groups (GI, GII, GII, GIII e GIV) for each experimental type. The GI ( n= 10) received 5,0 mg from PGF2α byintramuscular to vulvae way; the GII (n = 10) received 5,0 mg from associated PGF2 α the 8,0 mg of corticoids saw to intramuscular; the GII ( n= 10) was submitted the administration of 0,125 mg of PGF2 α by intramuscular to vulvae way and the GIV (n = 10) received 0,125 mg from the PGF2α by intramuscular to vulvae way, associated the 8,0 mg of dexamethasone by intramuscular way. On the other hand group GII presented difference statistics in the dry period, however it did not present difference statistic between groups in the different periods. It was concluded that the use of the synthetic prostaglandins associated or not to dexamethasone do not promote the artificial induction of the births without compromise the viability of the kids and the deliver of the afterbirth placenta. |
