Abstract
Rumen ciliates still have mysterious secrets and impacts in ruminants. This study evaluated the influence of seasons, breeds and rumen ciliatestransfaunationon physical examination, rumen fermentation pattern, serum and milk profiles in apparently healthy, defaunated and experimentally acidotic lactating dairy goats. Fifty-seven apparently healthy female lactating dairy goats aged 3.5±0.24 years old andweighted 32.45±1.19 kg, were used in this study. Forty-nine of them belonging to private farm in El-Beharah governorate, Egypt, were used in survey study and classified according to breeds into 17 Shami, 14 Mixed Boar and 18 Baladi, and according to seasons, they were classified into 12 Autumn, 13 Winter, 12 Spring and 12 Summer, while the other 8were classified intotwo groups each one contained 4 goats; Pure culture (PC) and Mixed culture (MC) in transfaunation experiment. Then, 6 of the 8 were used in experimentalinduction of rumen acidosis and classified according to treatment into two groups each one contained 3 goats; Conventional treatment (CT) and Mixed culture(MC). All of goats were exposed to detailed case history and comprehensive physical examination. Rumen fluid, serum and milk samples were collected from all goats before morning mealat the middle of each season in survey study, weekly for three consecutive weeks in transfaunation experiment and daily for three successive days in acidosis experiment. Regarding transfaunation experiment, PC group was transfaunated with 6 ml of pure culture of Holotricha counted 1.90 ± 0.49 X 104 per ml, while MC group was transfaunated with 6 ml of mixed culture of 81.85 % Holotricha and 18.15 % Ophryoscolexwith total count of 1.94 ± 0.51 X 104 per mlonce weekly for three consecutive weeks, after defaunation of both groups using 30 ml of 8 % SLS for two consecutive days
