Abstract

The aim of this study was to judge the efficacy of iodine preparations (intrauterine irrigation of lugol's 0.5% or supplementation of potassium iodide), oral supplementation of vitamin E, i.m. injection of vitamin E plus selenium or a combination of both i.m. injection of vitamin E plus selenium and intrauterine irrigation of lugol's iodine, for treatment of ovarian inactivity in cows and buffaloes. A total of 140 anestrous buffaloes (71) and cows (69), 4-9 years in age suffered from ovarian inactivity for more than 8 and 3 months, respectively. They were used to conduct this study in the period from 1997 to 1999. The involved animals included 30 buffaloes and 35 cows during the green season and 41 buffaloes and 34 cows during the dry one. They were individually kept and fed on imbalanced diets that did not satisfy their requirements especially for minerals by farmers scattered in the villages related to Sydi-Salem district Kafr El-Sheikh province. The selected bu ffaloes and cows proved to be anestrous due to ovarian inactivity (progesterone levels in their sera were less than 1 ng/ml) were allotted into 6 group according to the applied regimen of treatment as follows: 1- the first group (GI):

It included 12 buffaloes, 4 in dry season and 8 in green one and 9 cows, 5 in dry season and 4 in green one. Each animal was supplied with potassium iodide at a dose of 10 gm/head. 2- The second group (GIi):

It included 9 buffaloes, 6 in dry season and 3 in green one and 16 cows, 9 in dry season and 7 in green one. Each animal in fused 100 ml of lugol's iodine 0.5% intrauterine.
