Item The Effects of Non-Genetic Factors on Dairy Cattle Performance in East Africa Testing for Season and Parity Effects(1973) Kiwuwa, G.H.; Makerere University, Kampala, UgandaThe season of calving has often been recognized (Cannon, 1933; Woodward, 1945, Frick. et al 1947; Carter et al 1963) as one of the main sources of variation of the lactation milk yield of dairy cattle in the temperate environment. Consequently. Evaluation of animals under the temperate conditions entails dividing the year into appropriate seasonal groups (i.e. spring, summer, autumn, winter) for the purposes of adjusting the milk records.Item The Effects of Non-Genetic Factors on Dairy Cattle Performance in East Africa Estimation of the Seasonal and Parity Differences(1973) Kiwuwa, G.H.; Makerere UniversityThe weather and climatic regimes in the tropical one are such that seasonal grouping can be done by dividing the calendar year into either the dry and the rainy months or the hot, warm and the cool months of the year. In the Sub-tropical zones of India, Pakistan, Brazil, Egypt, Middle East and Australia, seasonal classification is to some degree similar to what is used for the temperate zone.Item Milk Composition and Yield Characteristics of Mpwapwa Cattle(1971) Kiwuwa, G.H.; Kyomo, M.L.; Makerere University College, Kampala, Uganda; Ministry of Agriculture, Mpwapwa, TanzaniaMajor dairy production traits of East African cattle have been studied by Mahadevan et al.(1961, 1962), and Marples (1963). Late age at first calving, low milk yields, long dry periods and short lactations among the indigenous cattle were reported in each case. Crossbreeding of European breeds of cattle with the indigenous types and upgrading of the indigenous to Indian Zebu were recommended after Galukande et al.(1926), andd Mahadevan and Hutchinson (1964), had conclusively demonstrated the merits of these schemes.
