| The efficacy of one or multiple doses of an injectable formulation of deslorelin (a GnRH agonist) was evaluated to induce estrus in anestrous bitches. Thirteen animals composed three groups: group 1 (n=5, single IM injection of 2mg deslorelin), group 2 (n=5, four IM injections of 2mg deslorelin in alternate days), and control group (n=3, four IM saline injections in alternate days). Daily clinical evaluations, sexual behavior, vaginal cytology, plasma progesterone concentration, ovaryhysterectomy and macroscopic evaluation of the uterus and ovaries were done. In group 1, none of the bitches showed signs of estrus, while two developed clinical signs and vaginal cytology of proestrus. In group 2, all animals presented proestrus, four presented estrus, and... |

| The objective of the experiment was to verify, through ultrasonography, the follicular activity of ostriches in different seasons of the year, correlating them with photoperiod, number of rainy days in each month and egg laying. Eight females were evaluated monthly, during 12 consecutive months in an ostrich farm located in the Center-West of Minas Gerais, Brazil. It was found that the time of the year for egg laying lasts for eight months, from June to January. The egg laying was positively correlated (r = 0.48; P<0.01) with photoperiod. However, there was no correlation between the egg laying and the follicular activity with the amount of rain. Considering the technique adopted, the right antimere offered better ultrasonographic access. The method was... |
