An exploratory survey was undertaken to describe and quantify the magnitude of lameness in 964 dairy cattle between October and December 1999 under urban (Addis Ababa), peri-urban (Sebeta and Kaliti), and urban farms in a secondary town (Debre Zeit). Based on herd sizes, these farms were classifi...

Thirty-six crossbred cows were used in a 2 X 2 factorial arrangement in a randomized block design to evaluate forages from two cropping systems (1 and 2) and feeding levels (ad libitum, (Level1)) or 80 percent of ad libitum (Level 2) on milk yield, live weight, and reproductive performance. Crops...
