A study conducted to evaluate seasonality in the reproductive status of Ethiopian highland sheep using slaughter animals.
This study is aimed to characterize progesterone profiles of Menz ewes during gestation with intent to gain insight into applied clinical endocrinology in early pregnancy diagnosis and monitoring of prenatal reproductive wastage. Mean hormone concentrations were basal, but increased and remained ...
A study undertaken to determine the progesterone concentration in the peripheral plasma of pregnant Ethiopian Zebu cows using the ELISA technique.
A total of 137 cycling Zebu cows, each receiving a single dose of prostaglandin PGF 2a were used in an oestrus synchronization programme on three different farms. Of the cows on the three farms, 60.6 and 90.5 percent showed over oestrus and luteolysis, respectively. Pregnancy rate to fixed time i...
Results of a study conducted to determine the conception rates of Boran cattle following artificial insemination of different times from the onset of induced oestrus compared with artificial insemination following natural oestrus.
Investigates progesterone levels during the oestrous cycle of Ethiopian Menz ewes using the ELISA technique and establishes minimum progesterone values that could be adopted in investigations on anoestrus, pregnancy diagnosis and prenatal reproductive wastage.
Reviews the reproductive biology of cows with emphasis on Bos indicus (Zebu) cattle. Presents the reproductive anatomy and endocrinology of the cow. Examines changes that occur at puberty, during oestrous cycle and at pregnancy. Describes measures of reproductive performance, causes of infertilit...
