A study was conducted on growth performance of the Lesotho indigenous chicken (LES) compared to two exotic lines, the New Hampshire (NH) and Rhode Island Red (RIR), from 3-days to 70 weeks of age, when moulting occurred. Growth traits that…
The origin of differences in growth parameters between impala from the Mara Research Station (Mara) and the Messina Experimental Farm (Messina) was investigated. Impala from both localities were harvested, and body weights (BW) and cold carcass weights (CCW) were measured…
A study was conducted to determine the in vivo and in vitro limestone solubility of different mixtures of small and large particle limestone. Small (0 - 1.0 mm) and large (2.0 - 3.8 mm) particles were blended to obtain five…
