      The annual reproductive changes in the testes and epididymis of the soft-furred field rat,Millardia meltada have been investigated. The males of this species are sexually quiescent between January and April. Two peaks of highest reproductive activity occur annually in October and December. Interstitial cells show seasonal activity which approximately parallels the condition of the testes and epididymis. A correlation of these changes with the environmental conditions during 1977–78 indicates that the lowest temperature, shortest daylength and natural conditions occurring after the rainfall are congenial for reproduction of this species.

      Interscapular brown adipose tissue was studied in pregnant and lactating females and compared with virgin females in inbred Wistar rats, using the histomorphology and quantitation of cell numbers. In pregnant females an increase in the interscapular brown adipose tissue weight, total fat content and total fat cell numbers associated with a decrease in adipocyte diameter was observed when compared with virgin females. The total lipid content and total fat cell number in the interscapular brown adipose tissue of lactating females showed a decrease when compared to the pregnant females. This suggests that pregnancy and lactation are accompanied by changes in the status of interscapular brown adipose tissue which may be related to the changes in energy metabolism in these physiological states.
