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...

To address the problem of restricted access to grazing by cattle in wet season in the Sahel, a grazing trial was conducted to study the effect of duration of grazing and grazing method on cattle nutrition and performance. Twenty-four intact steers weighing 259 kg (SD=62) were randomly allotted to...

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 ...

An experiment was conducted in 1996 and 1997 in semi-arid Niger, to determine the influence of supplementation (no supplement, millet bran + simple superphosphate, or millet bran + simple superphosphate + blood meal) for cattle and mulching (0 or 3 t ha-1 of Aristida sieberiana straw) on soil fer...

Study was conducted to determine turnover of water, nitrogen and energy in lactating Holstein x Boran cows. Nine cows (Bos indicus × B. taurus) between their 42nd and 420th the days of lactation were selected for this study. The crossbred cows had ad libitum access to water and a dried maize stov...

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...

Forty-eight heifers of two genotypes, Boran (Bos indicus) and Holstein×Boran, were allocated to three feeding levels equivalent to 1.0, 1.2 and 1.4 times calculated metabolisable energy requirements for maintenance (MEm). The experiment started at the onset of reproductive activity, when the Bora...

A survey was conducted from February to June of 1997 among livestock herders in two villages of Niger, Kodey and Toukounous, on their perceptions, practice, and problems of night grazing. Cattle and sheep were the species that were taken out for night grazing by the herders. Small herd size an...

Sxity-four Azawak male calves were used to study the effect of nocturnal grazing (NG) and supplementation (S) in the dry season on forage and water intake, faecal output, eating time and weight changes of cattle in the Sahel. Treatments were factorial combinations of four levels of NG (0, 2, 4 an...
