1. Candidate mutations used to aid the prediction of genetic merit for female reproductive traits in tropical beef cattle
ABSTRACT In this study, we aimed to provide a wet laboratory validation for a set of single nucleotide polymorphisms (SNP), which had been identified as candidate functional variants in silico. Genotyping for candidate SNP was performed in Brahman and Tropical Composite cattle. After quality control, 29 SNP were first investigated individually for their asso

2. Inseminação artificial em tempo fixo em primíparas nelore lactantes acíclicas / Fixed Time Artificial Insemination in Lactating Primiparous Acyclic Nelore Cows
The objective of this experiment was to evaluate the efficiency of a Fixed Time Artificial Insemination (TAI) protocol in an attempt to improve the reproductive performance of primiparous lactating acyclic Nelore cows. The experiment was conducted for a period of breeding season (BS) of 180 days. Were used 350 Nelore cows with body condition score (BCS) grea

3. Embryo transfer in no cycling Crioula and Quarter horse breeds treated with estradiol cipionate and long-acting progesterone
The aim of this work was to prepare the mares for embryo transfer. In group 1 (G1,treated, n=15), recipient mares in anoestrus or in a transition period were treated with 5.0, 3.0 and 2.0 mg of estradiol cipionate at the days 0, 1 and 2 respectively, beginning at the day of ovulation (DO). From the fourth day on, the mares this group received long-acting pro

4. Retorno ao estro pós-parto em ovelhas da raça Santa Inês e desempenho ponderal dos cordeiros: influência do manejo da alimentação e da amamentação
The return to the estrus and the postpartum weight of 60 Santa Inês ewe, as well as the lambs weight, from June to November of 2004 and 2005, were studied in Campo Maior (4 46 S and 4207 W), PI, Northeastern Region of Brazil. Blood samples were taken for the analysis of P4 and PRL in the sanguine plasma, at 15, 30, 45, 60, 75 and 90 days after the partum. T

5. Effects of nutrition on reproductive cyclic activity and on plasmatic melatonin concentration for ewes in pasture and submitted to the male effect, during seasonal anoestrus. / Efeitos da nutrição na atividade cíclica reprodutiva e nas concentrações plasmáticas de melatonina em ovelhas mantidas em pastagem e submetidas ao efeito macho durante o anestro sazonal.
O presente trabalho teve como objetivo avaliar os efeitos de diferentes condições nutricionais (suplementação e não suplementação) na atividade cíclica reprodutiva (ACR) em ovelhas das raças Santa Inês (SI), Romney Marsh (RM) e Suffolk (SU) mantidas sob pastejo, e submetidas ao efeito macho, durante época de anestro sazonal sob fotoperíodo natura

6. Episodic growth hormone secretion in sheep in relation to time of feeding, spontaneous meals and short term fasting.
1. Blood samples were taken every 20 min (for at least 28 hr) from five castrate male and two anoestrus female and libitum fed sheep. Analysis for plasma growth hormone (GH) showed that two of the males, on two occasions, had regular, although individually specific, patterns of GH secretion (peaks 3.5-5 hr). The other animals all had irregular patterns of GH
