African bovine trypanosomiasis caused by Trypanosoma sp., is a major constraint on cattle productivity in sub-Saharan Africa. Some African Bos taurus breeds are highly tolerant of infection, but the potentially more productive Bos indicus zebu breeds are much more susceptible. Zebu cattle are well adapted for plowing and haulage, and increasing their tolerance of trypanosomiasis could have a ma...
Infection rates in sterile male Glossina morsitans centralis, G. austeni, G. palpalis palpalis, G.p. gambiensis, G. fuscipes fuscipes, G. tachinoides and G. brevipalpis for Trypanosoma vivax, T. congolense and T. brucei isolated from East and West Africa, were studied. Five groups of the sterile males, together with the five groups of sexually fertile males, of each of the respective species an...
Studies on the trypanotolerance of Orma Boran X Maasai Zebu (Orma Zebu) crossbred cattle (F1 progeny) and pure-bred Maasai Zebu contemporaries were carried out in Nguruman, south western Kenya. The two groups were monitored from birth for a period of 2 years. The incidence of trypanosomosis, parasitaemia, packed cell volume (PCV), body mass and average daily mass gain were monitored. During the...

This paper studies the causal mechanisms behind poverty traps, building on evidence of nonlinear wealth dynamics among a poor pastoralist population, the Boran from southern Ethiopia. In particular, it explores the roles of adverse weather shocks and individual ability to cope with such shocks in conditioning wealth dynamics. Using original data, we establish pastoralists’ expectations of herd ...
We evaluated heifers crossbred from seven breeds of sires (Hereford, Angus, Belgian Blue, Piedmontese, Brahman, Boran, and Tuli) and three breeds of dams (Angus, Hereford, and MARC III [four-breed composite]). Heifers were mated to Red Poll sires to calve at 2 yr of age. Heifers were placed in two treatments from weaning to breeding and raised on a high nutrition level (15.8 Mcal ME/d) or on 80...

Understanding cultural preferences toward different ecosystem services is of great importance for conservation and development planning. While cultural preferences toward plant species have been long studied in the field of plant utilisation, the effects of ethnicity on ecosystem services identification and valuation has received little attention. We assessed the effects of ethnicity toward dif...
We compared fat distribution and lipoprotein lipase (LPL) activity in steers differing in adaptability to the subtropics. Steers were fed a grain diet (3.13 Mcal ME/kg DM) at limited (150 kcal ME x kg[-.75] x d[-1]; .23 kg ADG) or ad libitum levels for 140 d, then slaughtered. Sixteen British- (8 Angus, 8 Hereford; S), 16 Boran- (R), 16 Brahman- (B), and 16 Tuli- (T) cross steers from MARC III ...
