Abstract: Human chorionic gonadotropin (hCG) has been used to improve goats reproductive efficiency. This study aimed to (i) evaluate if hCG administered by the intramuscular (i.m.) or intravaginal (i.vag.) route can be detected by a rapid ?-hCG test in blood plasma samples and (ii) document ovarian effects of hCG administered by both routes at the time of artificial insemination (AI) performed 60?h after oestrus synchronization in goats. Twenty-two Alpine goats received two i.m. injections of 30??g of d-cloprostenol (Prolise®, Tecnopec, São Paulo, Brazil) 7.5?days apart. One day after the onset of oestrus (at the time of AI), the goats were randomly allocated to one of the three groups that received: control (n = 7): 0.3 ml of saline solution intravaginally; hCGi.m. (n = 7): 300?IU of hCG (Vetecor®; Hertape-Calier, São Paulo, Brazil) i.m. and hCGi.vag. (n = 8): 300?IU of hCG deposited intravaginally. Blood samples were drawn at ?1, 3, 6, 9 and 24?h after as well as on days 3, 7, 10, 13, 17 and 21 after hCG treatment/AI. All animals tested negative for hCG (ECO Diagnóstica, Corinto, Brazil) at ?1 h, and all control animals tested negative throughout the entire blood collection period. All hCGi.m. animals tested positive from 3 h until D3 post-AI but only 50% of hCGi.vag. goats tested positive during the present study.

Blood samples were drawn at ?1, 3, 6, 9 and 24?h after as well as on days 3, 7, 10, 13, 17 and 21 after hCG treatment/AI. All animals tested negative for hCG (ECO Diagnóstica, Corinto, Brazil) at ?1 h, and all control animals tested negative throughout the entire blood collection period. All hCGi.m. animals tested positive from 3 h until D3 post-AI but only 50% of hCGi.vag. goats tested positive during the present study. In all animals studied, mean circulating P4 concentrations increased (p?<?.05) from D3 to D7 after AI and then declined (p?<?.05) from D10 to D17 in control and hCGi.m. groups and from D17 to D21 in the hCGi.vag. group. Total cross-sectional luteal area (CLA), mean colour Doppler area (DA), DA/CLA, mean high-velocity Doppler area and HVDA/CLA all declined (p?<?.05) by D17?D21 in all animals studied. In summary: (i) human chorionic gonadotropin could consistently be detected in blood samples using the rapid ?-hCG test only in the hCGi.m. group; and (ii) there were no significant differences in the mean pregnancy rate, circulating P4 concentrations and various luteal parameters studied among Control, hCGi.m. and hCGi.vag. dose.

A maioria das bananeiras que produz frutos comestíveis é resultante da hibidrização intra/inter específica das espécies de diplóides selvagens Musa acuminata Colla (genoma A) e Musa balbisiana Colla (genoma B). Entretanto, as variedades cultivadas podem apresentar diferentes combinações genômicas: AA, AB, AAA, ABB, AAAA, AAAB, AABB e BBBB a depender do número básico de cromossomos. Não existem cultivares do grupo BB, BBB ou BBBB, provavelmente devido a ausência de partenocarpia o que não acontece normalmente com os diplóides AA (Ploetz et al., 2007).
O genoma B está presente na maioria das bananeiras produzidas mundialmente (Ssebuliba et al., 2006) e apresenta genes que conferem resistência a doenças e tolerância à seca, bem como maior valor nutritivo. |
