Inequality, population growth, and hunger in Sub-Saharan Africa.

Despite increasing population and inequality in most countries in Sub-Saharan Africa (SSA) and their tendencies to aggravate hunger there is still dearth of knowledge on their effects on hunger in the region. Therefore, the study used data for 46 SSA countries from 2007 to 2017 to examine the effects of inequality and population on hunger by adopting the System Generalized Method of Moment approach as it is specifically applicable in this situation.

Influence of exogenous corticosterone on testicular function and mating behavior of Nigerian indigenous cocks.

In bridging the knowledge gap on stress physiology of Nigerian indigenous chickens, this study investigated the effect of exogenous corticosterone (eCORT) as stress inducing agent on the testicular function and mating behavior of Nigerian indigenous cocks. Twenty-four (24) cocks and one hundred and forty four (144) hens (mating ratio of 1 cock: 6 hens) were grouped into four and assigned to each of the four eCORT treatments (0, 2, 4 and 6 mgeCORT/KgBW) daily for 14 days. Semen samples were collected on days 0, 7 and 14 and analyzed for semen volume (SV), progressive sperm motility (PSM), membrane integrity (MI) and sperm abnormality (SA).
