Seventy-four weekly weighband and weighbridge comparsons were made on 21 pure and crossbred Malawi zebu cattle. The mean correlation coefficient obtained was +0.977. The weighband over-estimated the liveweight by a mean of 42 lbs, which was equivalent to an 8.5 percent error. The highest individu...

The forest canopy is one of the chief determinants of the microhabitat within the forest. It affects plant growth and survival, hence determining the nature of the vegetation, and wildlife habitat. A plethora of different techiques have been devised to measure the canopy. Evaluation of the litera...

Two commercial laser dendrometers were tested under controlled and field conditions, and contrasted with alternative instruments. Testing focused on height Measurement, but also considered distance and remote diameter measurements. Both laser instruments gave very precise estimates, but showed so...

Despite extensive literature on the complex nature of empowerment, current efforts to measure women’s empowerment in the agricultural development sector are largely limited to assessing visible forms of agency. We take a critical look at current efforts to measure women’s empowerment at the indiv...

A total of 147 Menz and Horro lambs of both sexes were serially slaughtered and dissected at five different stages of growth to define the pattern of growth and partitioning of fat among body depots in indigenous Ethiopian Menz and Horro sheep breeds. The GLM procedure of SAS and allometric growt...
