  Goat Breeding Objectives in Relation To Agroecological Zonation Under Dryland Farming Conditions of North Kordofan, Sudan Authored by Faisal M El Hag Goats are one of the most important livestock species in rural farming systems in Sudan and the most widely distributed animal in the country. They occupy the second position after sheep in population size and third position in economic importance after cattle and sheep [1]. Increasing pressure on land and natural resources, poverty, hunger, changing climatic conditions, and pricing of livestock products driven by increased population and consumer demand present unprecedented development challenges for smallholder traditional dryland farming communities [2]. Improvement of livestock production using more productive livestock genotypes has been advocated as a sustainable means of improving the livelihoods of some of the poorest farmers [3].

Growth Response of Heterobranchus Longifilis Fingerlings Fed Diets Supplemented with Moringa Oleifera Leaf Meal as Replacement of Soybean Meal Authored by Ibiyo Lenient MO Aquaculture is the fastest growing sector of the world‘s animal production with an annual increase of about 10% [1]. To sustain such high rates of increase in production, a matching increase in fish feed production is imperative. Because fish meal is a limited primary source and plants are widely available and reasonably priced, the use of plant protein sources in aqua feeds should be considered [2]. Therefore, in order to attain more economically sustainable, environmentally friendly and viable production, research interest has been directed towards the evaluation and use of non-conventional sources of plant and animal protein. Soybean meal is one of the most nutritious of all plant protein sources because of its high protein content, high digestibility, and relatively well-balanced ami no acid profile [3]. Owing t...
