Abstract:This study is aimed at investigating the age related changes in postnatal development of red Sokoto goat stomach. In this study, a total of ten red Sokoto goat digestive tract samples were used and they were grouped into five (5) age categories (group A to E). The goat ages were estimated using dentition eruption and wearing. The stomach was identified and separated from the other part of digestive tract. The gross study revealed that the stomach was composed of four (4) segments that named; rumen, reticulum, omasum and abomasum with anatomical demarcations between them. The biometric study of weight, length, width, thickness, and volume was found to be increasing with advancement in postnatal ages with the following valves shows the mean value of weight, length, width, thickness and volume were to be 29 to 58.0 (g), 23.5, to 52.1 (cm), 15.4 to 29.0 (cm), 0.48 to 1.0 (mm) and102 to 432 (cm3) from group A to group E respectively. Based on the above findings it was suggested that more research should be conducted using histological techniques and electron microscopy in order to finalize on the findings.

Alley Cropping For Soil and Agricultural Sustainability in South Eastern Soils of Nigeria
Authors : Nweke I. A.
Abstract:The restoration and maintenance of soil fertility in south eastern soils of Nigeria is a basic critical environmental problem. It is especially serious because their soils lack plant nutrients and organic matter (OM) and intense rainfall experienced in the area erodes vulnerable top soil. The nitrogen fixing ability of tree legumes when used in alley cropping allows them to grow on difficult sites subject to erosion, low fertility or other adverse soil conditions. Alley once established can create conditions favourable for growth of other species leading to a balanced plant ecosystem. Tree legumes are a good source of OM for green manure their dry foliage contains about 2.5-5%N and leaf material incorporated into the soil improves soil fertility, moisture and nutrient retention and general tilth. At the same time by improving soil structure, erosion can be reduced.
