Ética e bem-estar em animais de laboratório / Ethics and welfare in laboratory animals

A utilização de animais de laboratório nos trabalhos experimentais de pesquisa científica tem sido de fundamental importância. Diversas espécies de animais são estudadas e utilizadas na experimentação, porém o camundongo é o animal mais usado nesses procedimentos, destacando-se como um modelo experimental de grande importância para a ciência. A cobaia é conhecida, por muitos, como símbolo representativo dos animais de laboratório, atualmente, as cobaias são muito utilizadas em experimentações ligadas à nutrição, farmacologia, imunologia, alergia, radiologia etc. Coelho é um modelo animal que destaca indubitável importância para o cresci-mento científico e tecnológico da sociedade no âmbito laboratorial. Um dos animais normalmente utilizados em laboratório é o hamster (Mesocricetus auratus) e isso se deve a seus atributos biológicos. A variedade doméstica de Rattus norvegicustem sido empregada para fins experimentais em virtude da facilidade de manejo, prolificidade, alojamento.

The use of laboratory animals in experimental scientific research has been of fundamental importance. Several species of animals are studied and used in the experimentation, but the mouse is the animal most used in these procedures, standing out as an experimental model of great importance for science. The guinea pig is known by many as a representative symbol of laboratory animals. Currently, guinea pigs are widely used in experiments linked to nutrition, pharmacology, immunology, allergy, radiology, etc. Rabbit is an animal model that highlights undoubted importance for the scientific and technological growth of society in the laboratory. One of the animals normally used in the laboratory is the hamster (Mesocricetus auratus) and this is due to its biological attributes. The domestic variety of Rattus norvegicus has been used for experimental purposes due to the ease of handling, prolificacy, lodging.

Distribuição dos partos na presença e ausência de luz em ovelhas Dorper / Distribution of births in the presence and absence of light in Dorper sheep

The aim of this study was to evaluate the distribution of births in the period of presence and absence oflight in Dorper sheep. forty sheep were used separately in two locations from the College of Technical Teresina,Piauí belonging to the Federal University of Finance and Paradise Herd in Belo Jardim, Pernambuco. Theanimals were subjected to a breeding season; as well as the diagnosis of pregnancy. The analysis of theincidence of the type of parturition, according to the presence and absence of light were obtained from thefollow-up observation and daily obstetric care until the time of delivery for later compared by chi-square test (P<0, 05). It was found that there was a higher incidence of parturições during the light period when comparedwith the periods without light. The conclusion of this research that the presence of light appears to influence the time of delivery of Dorper sheep.(AU)

Influência do ciclo lunar na determinação do sexo de cordeiros / Influence of lunar cycle in the parturition of the Dorper sheep breed

The aim of this study was to evaluate the influence of lunar phases in Dorper sheep, according to theproportion of births (single: double). Twenty were used two sheep from a breeding season. For the evaluation oflunar phases sheep were grouped proportionally according to the type of delivery (single: double). The analysisof the types of delivery were obtained according to the moon phases in place by the Brazilian NationalObservatory, being considered corresponding to the lunar phase where the maximum headquarters was up totwo days before and after the date of interest after being compared by the test chi-square test (P <0.05). It wasfound that there was a greater proportion of births in the crescent moon (P <0.05) compared to other lunarphases. The conclusion of this research that the crescent moon of the lunar phases, seems to affect the types ofdelivery of Dorper sheep.(AU)

Influência do tipo de parto na determinação sérica de glicose em cordeiros / Delivery type of influence on serum glucose determination in lambs

This study aimed to evaluate the effect of turn and type of birth on the behavior of the concentration ofglucose in Dorper lambs grazing in Piauí semiarid. 18 lambs were used in the Dorper, born aged twenty fourhours. For the evaluation of plasma concentrations of glucose, the animals were randomly distributed in shifts(day and night) and the type of birth (single and double). Blood samples were collected at 24 hours of elapsedtime after birth, soon after placed in tubes with sodium fluoride and taken to the Clinical Pathology Laboratoryof the University Veterinary Hospital - HVU, UFPI. Analysis of variance revealed a significant effect of theinteraction shift in the types of twin births (116.64 ± 6.28) on the concentration of plasma glucose. Theconclusion of this research was that the performance of twin lambs, is due to the amount of ingested colostrumdoes not depend directly on the amount of offspring or due to their own birth order.(AU)
