No effect of dieldrin on progesterone production in gilts.
The effect of feeding pigs with dieldrin containing feed on the progesterone profile of the estrous cycle was investigated. Eight gilts comprising three controls and five treatment animals were given feed containing 40 ppm of dieldrin for 60 days. Dieldrin levels in mg/kg fat in tissues analysed were; fat 15.15, muscle 18.68, liver 12.21, corpus luteum 13.68, kidney 14.16, serum 2.84 and brain 1.66. On analysing serum progesterone levels no significant difference (P > 0.10) between the progesterone profile of the control and the treatment animals was observed.
