Cratylia argentea, a drought tolerant shrub, is known to produce significant amounts of fodder during the dry season but little is known of its nutritive value for feeding animals. Two studies of quality and intake of Cratylia argentea, as an arboreal protein supplement for crossbred dual purpose...

The Caqueta region of Colombia is representative of the environmental and economic conditions prevailing in most of Colombia's Amazon region. The department of Caqueta, located in the Amazon River basin, occupies an area of 8.9 million hectares, most of it under jungle. The average annual rai...

Three experiments were conducted in successive years on crossbred suckler cows on a farm in a semi-arid area close to Nairobi, Kenya. The cows were mated seasonally to calve approximately 1 month before the rainy season (March to May). The effects of milking once daily and supplementation (2 kg/h...

Understanding the problems of grazing land in vertisol areas and seeking long-lasting solutions is the central point where mixed crop livestock is the second stay for the majority of the population. In order to understand this, the current study was conducted at two sites, one with 0-4% slope and...

Thiss paper presents an overview of the current status, problems and prospects for achieving a better nutrient balance to support varying levels of productivity from the three major livestock systems in Africa. In free range grazing systems, livestock nutrient deficiencies are mainly overcome by ...

Extending livestock grazing to the steep slopes has led to unstable grazing systems in the East African Highlands, and new solutions and approaches are needed to ameliorate the current situation. This work was aimed at studying the effect of livestock grazing on plant attributes and hydrological ...

Few studies have investigated how free-ranging wild herbivores adjust their food intake rate and nutrient gains during the dry season. Our study focused on the largest extant grazer, the white rhinoceros (Ceratotherium simum Burchell 1817). Field measurements were made on changes in bite mass, bi...

A single visit questionnaire survey was undertaken on 50 cattle owners in Oyo state, south western Nigeria. Data were collected on grazing patterns, calving dates, calf mortalities and attitudes to the N'Dama breed and its crosses with Bunaji cattle. All cattle herds had similar grazing patterns,...

From 2004 to 2010, the Sino-German research group MAGIM (Matter fluxes of Grasslands in Inner Mongolia as affected by grazing) ran a grazing experiment in a typical steppe ecosystem in Inner Mongolia, North China. Multiple ecological effects of grazing, climate variability and topography on plant...
