A static model for predicting either the growth rates or digestible organic matter (DOMI) required to meet predetermined levels of growth is developed. Parameters in the model were derived using data collected in ILRI-DZ laboratory from 6 growth studies (involving a total of 242 Ethiopian Menz sh...

The changes in soil pH and mineral N concentrations of cattle and sheep urine patches were compared to those occurring in fertilizer urea placement zones in a study in Niger. Urine and fertilizer solutions each containing 400 mg N (800 kg N/ha) were spread onto individual plots covering a surface...

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 ...
