Sessenta e duas fêmeas eqüinas foram distribuídas ao acaso em dois grupos experimentais de acordo com o intervalo da penúltima à última inseminação artificial de cada ciclo (48h ou 72h). As éguas foram rufiadas e inseminadas às segundas, quartas e sextas-feiras, a partir do momento em que apresentavam um folículo de 3,0 a 3,5 cm de diâmetro, com sêmen de apenas um garanhão de fertilidade comprovada, diluído para um volume inseminante de 10 mL com diluidor de mínima contaminação. As taxas de concepção referentes ao primeiro ciclo, para os intervalos de 48h e 72h foram de 66,67% (24/36) e 65,22% (15/23), respectivamente, sendo as taxas de concepção/ciclo de 53,45% (31/58) e 56,76% (21/37), na mesma ordem anterior. Com base nos resultados obtidos,... |

Verificou-se a influência do número de ordenhas diárias sobre a produção de leite, a duração da lactação, a incidência de mastite e o desempenho dos bezerros. Foram utilizadas 63 vacas primíparas e multíparas mestiças (Holandês-Zebu) com boa condição corporal ao parto, distribuídas ao acaso, por meio de sorteio, em três grupos experimentais com número igual de repetições, representadas pelo número de ordenhas diárias: vacas ordenhadas uma vez por dia; vacas ordenhadas duas vezes ao dia; vacas ordenhadas alternadamente a cada 14 dias, uma ou duas vezes ao dia. A saúde da glândula mamária não foi influenciada pela diminuição do número de ordenhas diárias. Não houve efeito do número de ordenhas sobre o desempenho dos bezerros, mesmo daqueles submetidos a uma... |

The aim of this study was to establish the morphologic and endocrine characteristics of luteal dynamics in goats. It was used Toggenburg female goats that showed natural estrus in a 48-hour interval. After estrus, ultrasonographic evaluations of the ovaries were daily performed during 21 days using a portable device (5MHz probe). Blood sample was collected for plasma progresterone (P4) determination. Corpora lutea were detected for the first time on day 5 and progressively increased in size until D9 (1.26 ± 0.08 cm²), with no variation on subsequent days. In females with one ovulation, the first visualization of the corpora lutea was earlier than in those with multiple ovulation (4.54 ± 0.18 vs 5.74 ± 0.25 days). At the moment of the first visualization,... |

ABSTRACT: This study evaluated the presence of vaginitis and the bacterial load associated with different intravaginal implants in ewes. Twenty-four Dorper and crossbred ewes were allocated into three groups and received intravaginal implant containing 0.3g progesterone (CIDR(r)), 60mg MAP or sponges without progesterone (CONTROL) for six days. Then, CIDR and MAP treated-ewes received 12.5mg dinoprost and 300IU eCG. Vaginal mucus samples were collected at four times: before device insertion, at the day of its removal, 24 and 48 hours after. The samples were cultured and the colonies were counted (CFU/mL) and identified. The results obtained from the counting of CFU mL-1 were submitted to Kruskal-Wallis H test, with P<0.05 being considered significant.... |

ABSTRACT: Reproductive efficiency is one of the key elements for any milk production system to be successful. In this regard, reproductive management must be planned properly and the identification of the main reproductive disorders that affect the herd is primordial for decision-making. The aim of the present study was to identify the main reproductive problems that affect dairy herds on Rio de Janeiro (RJ), Brazil. Data regarding breed, age, reproductive disorder occurrence, and breeding system were individually collected from dairy cows raised at 25 farms located at RJ. The occurrence of reproductive disorders was reported in 37% of the studied animals. Estrous repetition (76.2%) and abortion (15.6%) were the most frequent reproductive problems... |

The effect of the utilization of three semen protocols (Inra 82®, Merck Gema and Botu-crio®) and two filling techniques (0.25 and 0.50 mL straws) in Mangalarga Marchador stallions were studied in this experiment. Sperm parameters were assessed during processing and post-freezing. No interactions between the protocols and type of filling were observed, so they were assessed separately. Sperm parameters were not altered when the extender was added to the centrifugation; however, there was reduction of motility and strength when freezing extenders were added. The Botu-crio® protocol preserved the parameters of total and progressive sperm motility, smoothed path velocity (µm/s), straight line velocity (µm/s), track velocity (µm/s) and the average and fast... |

The objective of this study was to evaluate the efficiency of cyclic and acyclic progesterone-treated recipient mares in a commercial embryo transfer program. Acyclic recipients were treated with decreasing amounts of estradiol cypionate (ECP® - Pfizer Saúde Animal, São Paulo, Brazil), followed by 1500 mg of a sustained-release progesterone injection (P4LA150® - Laboratórios B.E.T., Rio de Janeiro, Brazil). Out of all 1506 embryo recovery attempts performed, 59.36% were positive (894/1506). Pregnancy rates of cyclic and acyclic mares were, respectively, 44.12% (319/723) and 57.68% (139/241) - higher in acyclic recipients under progesterone treatment. Embryo loss was similar between groups (9.72% 31/319 vs. 11.51% - 16/139). When fertility data on acyclic... |
