| intensive fattening of beef cattle by stall feeding on the lilongwe plain, malawi. i. type of forage and level and type of supplementation. | experiments were undertaken with malawi zebu steers over three wet seasons to investigate the effects of feeding improved forages (zero grazed) and supplements on animal performance. the forages fed were guinea grass and pearl millet and the supplements maize: madeya (maize bran) or maize: madeya: cottonweed cake. the daily allowance of supplement was, on a dm basis, liveweight equivalent to 0-6, 1-1 or 1-5 per cent of cattle (1973, 1974). in 1975 the supplementation treatments were nil, maize: ... | 1977 | 578596 |
| intensive fattening of beef cattle by stall feeding on the lilongwe plain, malawi. ii. utilisation of crop residues, crop by-products and leucaena. | experiments were conducted over three dry seasons to investigate the value for fattening beef cattle, of crop residues (maize stover, groundnut haulm) and madeya (maize bran) with varying levels of dried leucaena leaf or cottonseed cake. the inclusion of groundnut haulm in the roughage increased animal performance when madeya was restricted. increasing the protein content of the madeya supplement but restricting the quantity of madeya fed did not influence liveweight gain although the efficiency ... | 1977 | 595137 |
| intensive fattening of beef cattle by stall feeding on the lilongwe plain, malawi. iii. comparative productivity of malawi zebu and friesian x malawi zebu steers. | beef fattening experiments were undertaken on the lilonge plain with malawi zebu (mz) and friesian x malawi zebu (f x mz) steers. animals were fattened under various dietary regimes based on either green forage crops or crop residues supplemented with concentrate rations of local origin. mz steers consumed less feed and liveweight gain was approximately 75 per cent that of the f x mz. measurement of the efficiency parameters of feed conversion, gain and carcass yield per unit of liveweight revea ... | 1977 | 595138 |
| stocking rate and the productivity of rhodes grass pastures on the lilongwe plain, malawi. | an experiment was undertaken over three wet (summer) seasons to investigate the effects of different set stocking rates on animal performance from fertilised rhodes grass pastures. the three set stocking rates were 2.5, 5 and 7.5 livestock-units/ha (1 livestock unit=342 kg liveweight). pasture productivity was related to stocking intensity. animal gain per hectare was directly related to stocking rate. gain per animal, gain per livestock unit and number of grazing days were all inversely proport ... | 1978 | 625791 |
| intensive fattening of beef cattle on rhodes grass pastures on the lilongwe plain, malawi. | beef fattening experiments were conducted in two wet seasons with malawi zebu (mz) and friesian x malawi zebu (f x mz) steers grazing nitrogen-fertilised rhodes grass pastures. the effects of stocking rate (5,7-5 or 10 steers/ha) and level of supplement (maize: madeya (maize bran) fed to steers at either 0-6 or 1-5 per cent of liveweight) were investigated over a 100 day period. neither stocking rate nor supplement had an effect on daily liveweight gain but gain per hectare increased significant ... | 1977 | 906096 |
| the epidemiology of bluetongue in malawi. | a 4 year survey was undertaken in 1982-6 to examine the seasonal nature of bluetongue virus activity in malawi. bluetongue infection at bwemba in lilongwe district and likasi in mchinji district, both in the central region of malawi, was detected by examining sera taken from calves at each site, at monthly intervals. the proportion of seronegative calves undergoing seroconversion each month was used as a measure of virus activity. at both sides bluetongue virus activity was found to be most mark ... | 1988 | 2837408 |
| performance of cattle stall-fed for beef in malawi. | information on the initial and final weights, length of feeding period, grade of the live animal before slaughter, carcass weight and dressing percentage of 2,498 stall fed malawi zebu (mz) and crossbred steers from southern region and 2,085 steers from the central region of malawi is analysed. agricultural and household residues were the basis of the feeding system. the genetic composition of individual animals was not known; weight groups were therefore used as proxies for breed types. final w ... | 1988 | 3194976 |
| the distribution and epidemiology of bovine trypanosomosis in malawi. | a survey to update the distribution and clarify the epidemiology of bovine trypanosomosis in malawi was conducted between 1995-97. use was made of parasitological and serological (anti-trypanosomal antibody-detection enzyme-linked immunosorbent assay (elisa) diagnostic methods. trypanosomal infections were detected in cattle sampled adjacent to known tsetse foci. the distribution of cattle with anti-trypanosomal antibodies indicated that the distribution of bovine trypanosomosis was more widespr ... | 2000 | 10714455 |
