Concentraciones de hormona estimulante de la tiroides y tiroxina libre en ovinos jóvenes
This research aimed to establish reference values of thyroid-stimulating hormone (TSH) and free thyroxine (T4) in small ruminants under seven months old, by analyzing the influence of gender on determined values. Blood samples were collected from 48 fasting sheep (25 males and 23 females under 7 months old), and TSH and free T4 levels were determined using enzyme immunoassay. Average, minimum, maximum, and standard deviation values for TSH (μUI/ml) in young females were: 0.34; 0.0; 0.57; 0.15, respectively. In young males, they were: 0.09; 0.0; 0.57; 0.15, respectively. The F-test p-value was 0.147 (p ≥ 0.05), which indicates that there is no statistically significant difference with a reliability of 95% for TSH in young sheep with regard to gender. Average, minimum, maximum, and standard deviation values for free T4 (ng/dL) in young females were: of 0.44; 0.13; 0.73; 0.21, respectively. In young males, the values were: 0.66; 0.31; 1.17; 0.24, respectively. The F-test p-value was 0.04 (p < 0.05), which shows a significant difference with a reliability of 95% for free T4 values in young sheep. The study concludes that sex causes variation in the secretion of free T4 in young small ruminants.
期刊介绍:
The Revue de Médecine Vétérinaire publishes four kinds of text:
1) Scientific reviews on subjects related to veterinary and comparative medicine. Suggested length: 10 to 30 typed pages.
2) Original reports on fundamental or applied research. Suggested length: 10 to 15 typed pages.
3) Continuous education articles, that should be easily understandable by non-specialists. Suggested length: 10 to 15 typed pages.
4) Clinical reports. Suggested length: 5 to 15 typed pages.
The publication can be done in French language or English language.
For an article written in English by not english native speakers authors, the manuscript must be subjected by attesting that it was read again by an anglophone scientist or a scientific translator.
The authors must certify that the manuscript was not published or subjected for publication to another review.
The manuscript must be accompanied by a sheet signed by all the joint authors indicating their agreement for the tender of the manuscript.
The publication is free but a financial participation could be required for the photographs color. An estimate will be sent to collect the agreement of the authors.
