Thirty (30) weaned crossbred (Landrace × large white) pigs with an average body weight of 8.5±0.4 kg was used to evaluate performance and nutrient digestibility fed five experimental diets containing cereal milling by-products. Diet 1 contained maize offal, while 2, 3, 4 5 wheat sorghum millet offal rice respectively. The animals were balanced for sex then allotted dietary treatments replicated...

The Policy Research Working Paper Series disseminates the findings of work in progress to encourage the exchange of ideas about development issues. An objective of the series is to get the findings out quickly, even if the presentations are less than fully polished. The papers carry the names of the authors and should be cited accordingly. The findings, interpretations, and conclusions expresse...

We present BV RIZ photometric observations of HD 209458 during the transit by its planetary companion on UT 1999 November 15 with the University of Hawaii 0.6m and 2.2m telescopes and the High Altitude Observatory STARE telescope. The detailed shape of the transit curve is predicted to vary with color due primarily to the color-dependent limb-darkening of the star, but potentially due as well t...

We present optical and infrared spectra of SN 1999ex, which are characterized by the lack of strong hydrogen lines, weak optical He I lines, and strong He I λ10830,20581. SN 1999ex provides a clear example of an intermediate case between pure Ib and Ic supernovae, which suggests a continuous spectroscopic sequence between SNe Ic to SNe Ib. Our UBV RIz photometric observations of SN 1999ex start...

Le Burkina Faso dispose d’un potentiel de plus 800 000 ha pouvant servir à la riziculture. Cependant, d’importants facteurs naturels et anthropiques subsistent, affectant négativement production du riz. Sur le plan national rendement moyen riz dans les bas-fonds aménagés est 2,5 t ha-1 avec un 4t ha-1. Dans bas-fond Lofing, il varie entre 1,34 2,72 L'objectif présente investigation était capita...
