Turkish Journal of Veterinary & Animal Sciences
The objective of this study was to determine the effects of formic acid, molasses, and microbial inoculant (homofermentative lactic acid bacteria) as silage additives on silage quality and ruminal fermentation characteristics. Silages with or without formic acid (0.5%), molasses (5%), or microbial inoculant (10 g/t) were fed to ruminally cannulated, 1.5 year-old Kıvırcık x Morkaraman sheep. Silage treated with molasses had significantly greater DM and CP concentrations compared with other groups (P < 0.05). pH values did not significantly differ among treatments (P > 0.05). Lactic acid concentrations were significantly higher in silages treated with enzyme or molasses compared with others (P < 0.05). While acetic acid concentration was the highest in silage treated with acid, it was the lowest in silage treated with molasses (P < 0.05). Silage NH_{3}-N concentration was the highest in silage treated with molasses, but the lowest in silage treated with acid (P < 0.05). Post-feeding ruminal total organic acid concentrations were significantly greater in sheep fed silages with additive than the control (P < 0.05). While percentages of acetic acid were greater, percentages of butyric acids were less in the rumen fluid of sheep fed silage without additive compared with the rumen fluid of sheep fed silage treated with silage additives. However, percentages of propionic acid did not differ among treatments.

Immunohistochemical Localization Of Fsh Cells In The Pars Distalis Of The Pituitary Gland In Five-Month-Old Laying Hens, Hati̇ce Erdost
Turkish Journal of Veterinary & Animal Sciences
The present study was performed to determine the structural differences and immunohistochemical distribution of follicle-stimulating hormone (FSH) producing cells in the pars distalis region of the pituitary glands of 5 month-old laying hens, using the labeled avidin-biotin method. Hens begin to lay eggs at approximately the age of 5 months. It was observed that gonadotrophic cells containing FSH were present in both the cephalic and caudal zones and were densely distributed throughout the pars distalis. They appeared to be arranged in either cords or follicles in which branching and anastomosing occurred as well as being found as separate cells. The …

This study was conducted between January and May 2003 in small-holder sheep farms in Konya. A total of 471 faecal specimens obtained from 1-60 - day-old lambs were examined for the oocysts and coproantigens of Cryptosporidium parvum by Modified Ziehl Neelsen (MZN) staining technique and ELISA. The oocysts and coproantigens of C. parvum were identified in 14 (2.97%) and 43 (9.13%) of the 471 lambs, respectively. The infected lambs examined in the study were asymptomatically infected with C. parvum.
