Jenet, A.Tegegne, AzageOsuji, P.O.Yimegnuhal, A.Kreuzer, M.McCrabb, G.J.Fernández Rivera, S.[Weight development of lifetime underfed cows of different genotype (Zebu or Zebu x Friesian) in the tropics]Weight development of lifetime underfed cows of different genotype (Zebu or Zebu x Friesian) in the tropics

This study tested the hypothesis that purebred Boran (Bos indicus) cows and crossbreds of Boran and Holstein respond differently to long-term changes of feeding level in nutrient partitioning to milk and body fat stores. A total of 27 cows of these two genotypes were subjected either to a low or ...


Jenet, A.Fernández Rivera, S.Tegegne, AzageWettstein, H.R.Senn, M.Saurer, M.Langhans, W.Kreuzer, M.[Evidence for different nutrient partitioning in Boran (Bos indicus) and Boran x Holstein cows when re-allocated from low to high or from high to low feeding level]Evidence for different nutrient partitioning in Boran (Bos indicus) and Boran x Holstein cows when re-allocated from low to high or from high to low feeding level

Most supplementation experiments with fodder trees including S. sesban have been of short duration and focused mainly on feed intake and growth rate. Long-term studies regarding the effects of feeding S. sesban on reproductive performance of sheep particularly in both sexes are scanty. This study...


Mekoya, A.Oosting, Simon J.Fernández Rivera, S.Tamminga, S.Tegegne, AzageZijpp, A.J. van der[Effect of supplementation of Sesbania sesban on post-weaning growth performance and sexual development of Menz sheep (Ethiopia)]Effect of supplementation of Sesbania sesban on post-weaning growth performance and sexual development of Menz sheep (Ethiopia)

Two successive experiments were conducted to investigate the long-term effects of supplementation of Sesbania sesban on reproductive performance of Ethiopian Menz sheep. Forty ewes and 40 rams ranging in weight and age between 16–20 kg and 14–15 months respectively were fed a teff straw basal die...

Cowpea (Vigna unguiculata (L.) Walp.) is an important food legume and an integral part of traditional cropping systems in the semi-arid regions of the tropics. The estimated worldwide area under cowpea is about 14 million ha of which West Africa alone accounts for about 9.3 million ha with annual...


Singh, B.B.Ajeigbe, Hakeem A.Tarawali, Shirley A.Fernández Rivera, S.Abubakar, M.[Improving the production and utilization of cowpea as food and fodder]Improving the production and utilization of cowpea as food and fodder

A greenhouse trial was carried out at the International Crop Research Institute for the Semi-Arid Tropics (ICRISAT), at Sadore (13°15' N, 2°18'E), Niger. Experiments were conducted in conjunction with a feeding trial. The feeding trial yielded eight types of compost made from faeces and leftove...

The influence of 0, 60 or 120 min access to a grove of either Ziziphus mauritiana (Ziziphus) or Combretum aculeatum (Combretum) on forage intake and on the digestibility, growth and excretion of nutrients was determined using 40 Oudah rams grazing for 7 h/day on poor-quality dry season pasture in...

This conference was conducted to review the development of crop-livestock farming systems in West Africa over the preceding two decades with particular reference to the constraints, productivity, livelihood and environmental impacts; to assess future trends and determine new opportunities for sus...

Sesbania sesban is one of the exotic multipurpose fodder trees introduced in the Ethiopian highlands for livestock feed and soil conservation. Several on-station studies showed that supplementation with Sesbania improved intake and digestibility of basal diet and growth rate of animals. However, ...

Striga hermonthica causes serious crop yield losses in West Africa. Hand pulling, an effective method for the reduction of light infestations, might be encouraged if farmers could use this weed as livestock feed. This study evaluated the chemical composition and the voluntary intake and digestion...
