E-mail: paolasnoeck@uesc.br The aim of this study was to evaluate the efficacy of short-term hormonal treatments using Norgestomet reused implants on the estrous cycle control in dairy goats. Thirty five goats were divided in five homogeneous groups of seven animals each one. All female from the groups T1, T2 and T3 received 1/3 of Norgestomet implant of 1st, 2nd and 3rd use, respectively, + eCG (260 IU) + cloprostenol (75 μg); in the T4 group, ½ Norgetomet implant of 2nd use + eCG (260 IU) + cloprostenol (75 μg) and the T5 group, sponge impregnated with MAP + eCG (260 IU) + cloprostenol (75 μg). The AI was developed 45±1 hours after finishing hormonal treatment. In data analysis the Qui-square test was used to compare hot female number and pregnant rate while the characteristics: the final interval of the treatmentonset estrus (FT-OE), and estrus length (EL), were compared by Duncan tests using the statistic software (SAEG, 2000). The estrus behavior was observed in 100.0%, 85.7%, 85.7%, 100.0% and 100.0% of goats from T1 to T5 groups, respectively. The FT-OE intervals in the T3 and T4 (17.0±5.9 h and 15.4±9.1 hours) were smaller (P<0.05) than T1, T2 and T5 groups (29.1±15.3; 23.0±7.0 and 30.0±6.9 hours; in the same order), which did not differ from each other. The T1 and T3 groups, showed a bigger and a smaller variation on the FTOE interval, respectively (48 and 12 hours). The estrus length was similar in all groups (24.9±9.4; 28.0±9.8; 27.0±6.3; 22.3±5.7 and 24.0±6.9 hours; from T1 to T5). The pregnant rate of the T3 group (14.3%) was smaller (P<0.05) than other groups T1, T2 and T5 that did not differ from each other (71.4%; 71.4%; 85.7% and 71.4%, to T1, T2, T4 and T5, respectively). In conclusion, the use of 1/3 of 3rd use implant, although being effective for estrus induction, it doesn’t provide a satisfactory pregnant rate. On the other hand, the fractions of 1/3 of 1st and 2nd use implant of Norgestomet are efficient for estrus and ovulation synchronization, making possible to achieve satisfactory pregnant rate and recommend its use in fixed-time artificial insemination programs in dairy goats. |

Trinta e cinco cabras leiteiras foram divididas em cinco grupos homogêneos constituídos de sete animais cada. Em todas as fêmeas dos grupos T1, T2 e T3 foi administrado, por via subcutânea, 1/3 de implante de Norgestomet de 1º uso, 2º e 3º uso, respectivamente, + eCG (260 UI) + cloprostenol (75 μg); nas do Grupo T4, ½ implante de Norgestomet de 2º uso + eCG (260 UI) + cloprostenol (75 μg) e no Grupo T5, esponja com MAP + eCG (260 UI) + cloprostenol (75 μg). A IA foi realizada 45±1 hora após o final do tratamento hormonal. Na análise dos resultados foi utilizado o teste Qui-quadrado para comparar o número de fêmeas em estro e a taxa de prenhez, enquanto que as características: intervalo final de tratamento-início do estro (FT-IE) e duração do estro (DE) foi comparado pelo teste Duncan, utilizando-se o programa estatístico SAEG (2000). O comportamento do estro foi verificado em 100,0%, 85,7%, 85,7%, 100,0% e 100,0% das cabras dos grupos T1 a T5, respectivamente. Os intervalos FT-IE nos grupos T3 e T4 (17,0±5,9 e 15,4±9,1 horas) foram menores (P<0,05) que nos grupos T1, T2 e T5 (29,1±15,3; 23,0±7,0 e 30,0±6,9 horas; na mesma ordem), os quais não diferiram entre si. Os grupos T1 e T3 apresentaram a maior e a menor variação do intervalo FT-IE, respectivamente (48 e 12 horas). A duração do estro foi semelhante em todos os grupos (24,9±9,4; 28,0±9,8; 27,0±6,3; 22,3±5,7 e 24,0±6,9 horas; para T1 a T5). A taxa de prenhez do grupo T3 (14,3%) foi menor (P<0,05) que dos demais grupos, os quais não diferiram entre si (71,4%; 71,4%; 85,7% e 71,4% para T1, T2, T4 e T5, respectivamente). Conclui-se que o uso de 1/3 de implante de 3º uso, embora seja eficaz para indução do estro, não proporciona taxa de prenhez satisfatória. Por outro lado, as frações de 1/3 de implante de 1º e 2º uso de Norgestomet são eficientes para sincronização do estro e da ovulação, possibilitando taxa de prenhez satisfatória, podendo ser recomendado o seu uso em programas de inseminação artificial em tempo fixo em cabras leiteiras.Sociedade de Medicina Veterinária do Estado do Rio de Janeiro.2010-12-15info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionpeer reviewedAvaliado pelos paresapplication/pdfhttps://rbmv.org/BJVM/article/view/859Brazilian Journal of Veterinary Medicine; Vol. 32 No. 4 (2010); 219-224Revista Brasileira de Medicina Veterinária; v. 32 n. 4 (2010); 219-2242527-21790100-2430reponame:Brazilian Journal of Veterinary Medicineinstname:Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)instacron:SBMVporhttps://rbmv.org/BJVM/article/view/859/711Cruz, Maria Helena Coelhoda Cruz, Jurandir FerreiraMoura, Luís Cláudio de OliveiraNeto, Milton Rezende TeixeiraFerraz, Rita de Cássia NunesSilva, Sandra Cristina BeckerSnoeck, Paola Pereira das Nevesinfo:eu-repo/semantics/openAccess2020-12-23T17:27:34Zoai:ojs.rbmv.org:article/859Revistahttps://rbmv.org/BJVMONGhttps://rbmv.org/BJVM/oaicontato.rbmv@gmail.com2527-21790100-2430opendoar:2020-12-23T17:27:34Brazilian Journal of Veterinary Medicine - Sociedade de Medicina Veterinária do Estado do Rio de Janeiro (SOMVERJ)false |
