The impact of a bacterial inoculant on chemical composition, aerobic stability and in sacco degradability of corn silage and the subsequent performance of dairy cows

To determine the effect of bilateral uterine artery ligation (bual) on mast cell (mc) distribution, 24 mature female rabbits were studied. the rabbits were ovariohysterectomized on day 23, 43 or 63 following bual. histological sections were stained with toluidine blue to determine the mc distribution. in rabbits that had undergone bual, mcs were present extensively in the helium ofthe treated ovaries, in dense groups close to the blood vessels. in the control group, mcs were observed at a medium density around the blood vessels and the number of mcs in the reproductive tract was significantly (p =< 0.01) lower than in the test groups. this study demonstrates that, after bual, the distribution and numbers ofmcs differ between different parts ofthe reproductive system.
