Chemical composition of four parasitic plants harvested over a period of 6 months from two sites in Botswana
(Elservier, 2002-02-25)Samples of four parasitic plants, Tapinanthus lugardii, Erianthenum ngamicum, Viscum rotundifolium, and V. verrucosum were obtained from Sebele Research Station and Sunnyside Ranch. Sampling took place in the 6 months ... -
Ostrich feeding and nutrition
(Asian Network for Scientific Information, 2003)Ostriches are monogastric herbivores. Palatability is crucial to stimulate feed ingestion by the birds. When formulating rations for ostriches, cotton seed cake, meal or seeds should not be used to avoid gossypol poisoning. ... -
Influence of Feed Type on Egg Production of Tswana Laying Chicken
(Ansinet, 2003)The experiment was done at estate management Unit in Sebele, Gaborone. Ten 23 weeks old laying Tswana chickens were bought from a local farmer and divided into two groups of five each, using complete randomized design. ... -
The use of indigenous parasitic plant (Viscum verrocosum) in reducing faecal egg counts in female Tswana goats
(Fundación CIPAV,, 2003)A study was carried out to evaluate the potential benefit of feeding a diet containing Viscum verrucosum on reducing faecal egg count (FEC) in female Tswana goats. Twelve animals, which had naturally acquired intestinal ... -
Carcass analysis and meat composition of the donkey
(Asian Network for Scientific Information, 2003)The objective was to determine the meat yield, proximate and mineral composition in donkey carcasses, aged between 5-8 years. Proximate analysis of the minced carcass was done and reported as moisture, dry matter, crude ... -
Correlated responses in tissue weights measured in vivo by computer tomography in Dorset Down sheep selected for lean tissue growth
(Bureau for Scientific Publications, 2003)The aim of this study was to estimate correlated responses in lean, fat and bone weights in vivo in Dorset Down sheep selected for lean tissue growth. Over the period 1986-1992 inclusive, the lean tissue growth line had ... -
Lucerne, Lablab and Leucaena leucocephala Forages: Production and Utilization for Livestock Production
(Asian Network for Scientific Information, 2003)An overview is given of three legume pastures with potentials as sources of crude protein and other important nutrients for livestock production in Botswana. This paper reviews distribution, plant description, agronomic ... -
Experimental and numerical evaluation of analytical volume balance model for soil water dynamics under drip irrigation
(Soil Science Society of America, 2003)The interpretation and subsequent modeling of soil water dynamics in presence of active plant uptake remains a challenge. Despite many simplifying assumptions in their development, analytical models offer simple and easy ... -
Dry matter and crude protein degradability of four parasitic plants (Mistletoes) associated with browse trees in Botswana
(Springer, 2003)Four parasitic plants (Tapinanthus lugardii, Erianthenum ngamicum, Viscum rotundifoliumand Viscum verrucosum) associated with browse trees in Botswana were evaluated for the degradability of their dry matter (DM) and crude ... -
The Influence of topography and vegetation canopy on the deposition of atmospheric particulates Studied with 210Pb and 137Cs soil inventory measurements
(University of Edinburgh, 2003)Naturally occurring radioactive isotopes of 210Pb and 7Be in the atmosphere, plant material and soil have been used to investigate the transport and removal of atmospheric aerosols from the atmosphere by precipitation and ... -
Feeding Values and Anti - Nutritive Factors of Forage Tree Legumes
(Asian Network for Scientific Information, 2003)Animal production in Botswana suffers from inadequate feed quantities and qualities, due mainly to semi-arid low rainfall which can barely support arable farming in most years. This problem is compounded by the competition ... -
Atriplex Nummularia (Old Man Saltbush) : A Potential Forage Crop for Arid Regions of Botswana
(Asian Network for Scientific Information, 2003)Atriplex nummularia (Old man saltbush) is widely planted on salt affected land to provide a vegetative cover, which can be used as fodder reserve. Such plantations are also perceived as having the capacity to use saline ... -
The effects of vaccination and treatment on the spread of HIV/AIDS
(World Scientific Publishing, 2004)This study investigates the effects of vaccination and treatment on the spread of HIV/AIDS. The objectives are (i) to derive conditions for the success of vaccination and treatment programs and (ii) to derive threshold ... -
Foraging strategies of sheep and goats under semi-intensive management in Botswana
(Bureau for Scientific Publications, 2004)Diet selection of sheep and goats was determined seasonally using the microhistological technique to assess their trophic diversities, diet overlapping and preferences between the two species. The trophic diversities of ... -
Comparison of Laboratory pH Buffer Methods for Predicting Lime Requirement for Acidic Soils of Eastern Botswana
(Taylor & Francis, 2004)The suitability of pH buffer methods that determine lime requirement (L.R.) of acid soils of the eastern region of Botswana has not been determined, and the soil physiochemical properties that influence L.R. are not known. ... -
Azanza garckeana: A Valuable Edible Indigenous Fruit Tree of Botswana
(Asian Network for Scientific Information, 2004)Azanza garkeana (morojwa) is a valuable edible indigenous fruit tree species confined to east and southern Africa. Because of its multiple use the species is selected and retained by farmers in Botswana when they clear the ... -
Ngoro: an indigenous, sustainable and profitable soil, water and nutrient conservation system in Tanzania for sloping land
(Elservier, 2004)The Matengo people, in SW Tanzania, developed the ngoro conservation system several hundred years ago and it is a very effective indigenous manual cultivation practice for steep slopes. It deserves wider recognition and ... -
Potentials of Guinea Grass (Panicum maximum) as Forage Crop in Livestock Production
(Asian Network for Scientific Information, 2004)Panicum maximum (guinea grass) is native to Africa but this grass was introduced to almost all tropical countries as a source of animal forage. It grows well on a wide variety of well drained soils of good fertility and ... -
