The influence of night grazing on feeding behavior, nutrition and performance of cattle was studied. Twenty-four steers weighing 367 kg (SD = 76) grazed either from 0900 to 1900 (day grazers), 2100 to 0700 (night grazers) or 0900 to 1900 and 2400 to 0400 (day-and-night grazers) during 13 weeks. F...

A selective breeding program was implemented to improve the performance of indigenous chickens. Improved chicken from the 7th generation were compared with commercial layer, crossbred and unselected indigenous chickens both on-station and on-farm. A total of 870 chickens were used. More than 600 ...

Indigenous knowledge is unevenly distributed. Individual knowledge level may be affected by many factors such as gender, age, ethnicity, profession, religious and cultural beliefs, abundance and usefulness of the species. This study documents indigenous knowledge of herbaceous and woody plant spe...

A cross-sectional stratified random sample survey of 1755 households in the Kenya highlands was conducted between June 1996 and April 1998 to quantify cattle population dynamics in smallholder herds. The free-, semi-zero- and zero-grazing systems practised represented increasing levels of intensi...

Knowledge pertaining to local plant species in West African Sahel has been poorly documented despite the central role local vegetation plays in the everyday lives of the rural people. An ethnobotanical study was conducted between April and November 2005 to document knowledge and uses of local her...

This study aimed at better understanding of the characteristics of feeding and breeding practices smallholder farmers adopt in intensifying their dairy production. Use of hired labour for fodder gathering, growing of fodder crops and purchase of feeds increased with increasing intensification, bu...

Despite the large numbers and importance of adapted indigenous sheep and goats in the tropics, information on sustainable conventional breeding programmes for them is scarce and often unavailable. This paper reviews within-breed selection strategies for indigenous small ruminants in the tropics,...

A stratified random sample, cross-sectional survey of 1755 households in the Kenya highlands was conducted between June 1996 and April 1998 to evaluate the rationale underlying smallholders’ breeding decisions. Additional data were collected in a follow-up survey of 50 households sub-sampled from...

The selective use by cattle of range resources in the Sahel was assessed in terms of quantity and nutritional quality of the herbage grazed and diet selected. Peak standing crop was 1951 kg ha -1 dry matter (DM) with 47.9 kg nitrogen (N) ha-1 and 7.4 kg phosphorus (P) ha -1. Esophageally fistulat...

The objective of this paper is to compare the concepts of Sustainable Development (SD) and Gross National Happiness (GNH) to assess development at various level, especially at the smallholder crop-cattle farming systems level in Bhutan. The concept of SD was conceived about two decades ago, while...
