Resumo: In the present study 21 young female swines, sexually mature, reared and kept under a industrial management system were assessed for its progesterone serum profiles during the oestrus cycle. Blood sampling was performed always at the same interval, from 8:00 to 10:00 AM. Each animal was submitted to 14 venal punctions at days 0, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 21, 22 and 23 of the oestrous cycle. the first day of the oestrous phase was assumed to be Day 0 and the 23rd as the first of the next cycle. Hormone determinations were performed employing a solid phase radioimmunoassay (RIA). Highest T3 concentrations were observed at the 1st and 23rd days and minimul values for the 12hd of the oestrus cycle. Regarding T4, the concentration values ranged from 2.42 and 3.74 mug/dl.

As colheitas de sangue foram efetuadas sempre no mesmo intervalo, entre 8 e 10 horas. Cada animal foi submetido a 14 punções venosas, distribuídas nos dias zero, 2, 4, 6, 8, 10, 12, 14, 16, 18, 20, 21, 22 e 23 do ciclo estral. Consideramos o dia zero como o primeiro dia da fase estral, e o 23º dia como o primeiro do estro subseqüente. Os ensaios para dosagens hormonais foram executados utilizando-se a técnica de radioimunoensaio (RIE) em fase sólida e para isso foi empregado conjunto de reagentes comerciais (Coat-A-Count®). Para o hormônio triiodotironina foram observados valores altos no 1º e 23º dia e valor mínimo no 12º dia do ciclo estral. O hormônio tiroxina apresentou valores que oscilaram entre 2,42 e 3,74 mig/dl.Universidade de São Paulo.
