Resumo: | The objective of this study is to determine the efficiency of PGF2-OL analogue (Cloprostenol, ICI-80.996) in the synchronization of the estrous cycle and the fertility level in Nelore cows from a farm adjacent to Londrina, Paraná State. On the first day of the trial, 132 cows were selected after genital examination, the majority of them, 7 to 9 months after parturition and the rest barren during the previous year. These animals were distributed at random into three groups of 44 each. Groups I and II received two doses of 0.5 mg of Cloprostenol through intramuscular route 11 days apart. Group I animals were inseminated twice at 72 and 96 hours after while those in group II were inseminated once, aproximately 12 hours after the heat detection by teaser bulls with chin-ball. The third group received no treatment and served as control, following the same scheme as group II over a fixed period of 21 days. The results obtained were as follows: Group I - without having any concern over the symptoms of heat, 24 (54,54%) cows became pregnant and from the other 20,70% repeated a normal cycle. Group II-between the 2nd and the 8th day, 42 (95,45%) cows showed signs of heat and were inseminated, 15 of them (34,09%) became pregnant and from the 27 animals that were not pregnant 18 (66.66%) returned to heat 19 to 22 days later, confirming the data observed in the previous group. Group III - heat and insemination rates of43 (97.72%) cows resulted in 16 (36.36%) pregnancies while rest of the animals returned to the regime of natural service. The conception rate between groups were not significantly different (P > 0.05). |

Estudo da eficiência da PGF2-a análoga (Cloprostenol, ICI-80.996) na sincronização do ciclo estral e a fertilidade no cio sincronizado. Pesquisa efetivada em rebanho da raça Nelore nas proximidades de Londrina, Paraná. No primeiro dia do experimento, após exame genital, foram separadas 132 vacas, na maioria com 7a 9 meses de paridas e as restantes, falhadas no ano anterior, formando, ao acaso, três grupos de 44. Dois grupos (1ell) receberam duas injeções de 0,5 mg de Cloprostenol por via intramuscular com 11 dias de intervalo. Os animais do Grupo I foram inseminados em períodos pré-fixados (72 e 96 horas) depois da segunda aplicação. O grupo II permaneceu com rufiões portadores de "chin-ball" e as inseminações aconteceram cerca de 12 horas após a identificação do cio. O terceiro grupo serviu como testemunha e o esquema de observação de cio e de inseminação foi o mesmo adotado no Grupo II, por um período de 21 dias. Os resultados obtidos foram os seguintes: Grupo I - sem qualquer preocupação com os sintomas de cio resultou 24 (54,54%) vacas gestantes e das outras 20, houve um retorno sincronizado de 70%. Grupo II - entre o 2o. e 8o. dia, exibiram cio e foram inseminadas 42 (95,45%) vacas e ficaram prenhes 15 (34,09%). Das 27 vacas que não enxertaram, 18 (66,66%) repetiram ciclo normal, confirmando os achados do grupo anterior. Grupo III - o índice de cio e inseminação atingiu 43 (97,72%) vacas, resultando 16 (36,36%) gestações e as demais, voltaram para o regime de monta natural. O índice de fertilidade entre os grupos estudados não foi estatisticamente significativo (P> 0,05).UEL1980-02-05info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/580810.5433/1679-0359.1980v2n5p49Semina: Ciências Agrárias; Vol. 2 No. 5 (1980); 49-52Semina: Ciências Agrárias; v. 2 n. 5 (1980); 49-521679-03591676-546Xreponame:Semina.
