Urine of mature males was the most attractive type of mature and pregnant females and immature males and females (36.00, 32.00, 42.76, 34.40 second / visit) respectively. Also, urine of estrus females was the most attractive type of adult males, pregnant females and immature males and females (62.80, 40.50, 36.83, 37.03 second / visit) respectively. The most attractive vaginal smear to all tested animals was that taken from adult females during estrus phase ,while the least effective vaginal smear was that obtained from pregnant and lactating females except for the immature females where the lactating smear was more attractive like estrus one. The most attractive fecal matter to the mature males in the lateral passage was that taken from lactating females and mature males (21.53, 21.86 second / visit) respectively ,while the least effective fecal sample was that taken from estrus and pregnant females (8.16, 8.16 second / visit) respectively. In addition the most attractive fecal matter to the mature females was that taken from adult males (34.86 second / visit) while the least attractive fecal sample to the mature females was that taken from pregnant and estrus females (1.00, 3.66 second / visit) respectively. |
