Avaliação do estresse hipertérmico de ovelhas gestantes das raças Dorper, Santa Inês e suas mestiças em clima tropical com base nos níveis sorológicos de Triiodotironina (T3) e Tiroxina (T4 Total) / Evaluation of the stress head stress sheep pregnant of the breeds Dorper, Santa Inês and their mixed in a tropical climate based on the serological levels of Triiodotironina (T3) and Thyroxine (T4 Total)

The study objectify to evaluate the adaptability of pregnant sheep of the Dorper, Santa Ines and mixed(Dorper ½ ½ Santa Ines) to the tropical climate through serologic possible modifications of triiodothyronine(T3) and thyroxine (T4). The experiment was conducted at Malhada Vermelha farm in Lagoa Alegre - PI, 21sheep were used in gestational middle third, 7 of Dorper, 7 Santa Ines and 7 mixed (Dorper x Santa Ines), all insatisfactory clinical conditions and under the same management conditions. These were evaluated respiratoryrate, rectal temperature and collected blood samples for hormone dosage four times in each climatic periodMarch, July and October. Later they were measured Thyroxine (Total T4) and triiodothyronine (T3) by ELISA.T3 dosages remained within the normal range for the species, while T4 was below. It was concluded that themost adapted breed is Santa Ines.(AU)

Efeito pró-erétil em ratos tratados com extrato etanólico das vagens de Senna spectabilis / Pro-erectile effect in rats treated with ethanol extract of pods of Senna spectabilis

This study aimed analize the Pro-erectile effect of rats trated with ethanol extract os pods of Sennaspectabilis (EEVSs), a native plant from Savana, predominant on brazilian northwest. Compreendendo que Thefeed is an important aspect for the development of good breeders and reproductive risk of failures caused byempirical use of native plants in the feeding of cattle can not be ignoredWere used 40 Wistar rats separated inthree groups treated with EEVSs and one group treated with apomorphine and another treated with distilledwater. After each treatment the animals were observed In a transparent chamber. The rats that received theEEVSs showed no significant alterations. However at presence of apomorphine there was an increase of penileerection, for it is an dopaminergic agonist.(AU)

Frequência de ejaculação de ratos tratados com extrato etanólico de Senna spectabilis / Ejaculation frequency of rats treated with ethanol extract of Senna spectabilis

This study aimed analyse the effects of Senna spectabilis on ejaculatory frequency and copulatoryparameters of rats, getting some answers related to aphrodisiacs and adverse effects and potential influencers inthe sexual behavior of animals observed in some species of plants similar to Senna spectabilis. Were used 35Wistar ratos, being 28 with erectile dysfunction induced by paroxetine The ethanol extract of S. spectabilis(EESs) were administered in three different doses (250, 500 and 1000 mg/kg body weight) for seven consecutivedays. Then the rats were allocated in cages with female rats at estrus phase and the ejaculatory frequency wasnoted. The animals in this study showed no erection while they were on observation and no significantbehavioral change was observed, compared to the control group.(AU)

Pesquisa de atividade androgênica e antiandrogênica em ratos tratados com extrato etanólico das vagens de Senna spectabilis / Evaluation of Androgenic and antiandrogenic activity in rats treated with ethanol extract of pods of Senna spectabilis

Although the high expression of the northeastern herds, the levels of productivity, reproducibility,carcass gain and other factors are low. This is mainly due to the main food source being from native plants ofthe Savanna. Were used male Wistar rats (64) divided into eight groups. These animals were castrated and, afterrecovery, received ethanol extract of pods of Senna spectabilis (EEVSs) in three different doses and testosteroneintramuscularly (some groups). The animals were treated for 32 consecutive days and at the end wereeuthanized. The organs were collected and weighed for evaluation of androgenic and anti-androgenic activity.The extract showed no androgenic nor anti-androgenic activity at the doses tested.(AU)

Sensibilidade de cabras da raça Anglonubiana a infecção por verminose no periparto indicada pelo OPG / Sensibility of goat breed Anglo-Nubian infection by nematode parasites in peripartum indacated by OPG

The objective of this research was to evaluate the relationship of the infestation of gastrointestinalnematodes with the occurrence of peripartum in the angonubiana breed goats were divided into two age groups:Young goats <4 years old and Goats> 4 years. The set of information corresponds to the period from 2009 to2015 obtained from the Bank of UFPI the goat herd data, which is located in Teresina - PI. There was nosignificant difference in the samples taken during pregnancy (P > 0.05), although in the final third of the OPGtended to grow. Therefore, without significant evidence of peripartum express sensitivity of animals toparasitism. So in herd infected continues throughout the year tends to be little influence on the time of year in thegoat parasitism degree during pregnancy and lactation, regardless of age. However, does not imply inattentioncurative measures in the peripartum.(AU)
