Canopy Changes in Healthlands (Erica-Ulex) Grazed by Sheep or Goats
The grazing effects of sheep and goats on vegetation dominated by heaths (Erica spp) and gorse (Ulex gallii) were studied for two years. Two plots were grazed from May to October 1992 by 7 ewes or 7 does and in the following year each plot was subdivided into two subplots subsequently grazed either by sheep or by goats in a factorial design. During the first grazing season both sheep and goats reduced similarly the cover percentage of shrubs since the herbaceous content was scarce, although goats reduced more the height of the shrubs than sheep. The cover of dead matter increased notably in both treatments due to the new gaps formed in the canopy. In the second year the different grazing behaviour of sheep and goats became apparent in the vegetation since the content of shrubs decreased and herbaceous species increased more in the goat than in the sheep grazed plots
Econometric Data Analysis Affecting Performance of Supply Chain Systems in the Petroleum Industries in Kenya
The purpose of this paper was to do econometric data analysis on performance of supply chain systems in the petroleum industries in Kenya. Specifically, the objectives of the study were to establish whether there is any effect from; level of skills, information and communication technology and tendering systems and the moderating factor have an effect on supply chain systems performance. The study was conducted using a survey design. The total population of all oil companies in the 73 was covered by the study. Several studies were carried to validate the final findings. Finally, this statistics concluded that there is need to do econometric data analysis to validate the effect of supply chain systems on performance by doing proper forecasting from the up streams to the down streams towards achieving a competitive edge in the business markets such as the petroleum industry. The econometric analysis focused on the these areas; Information functions in order to inform management, support decision making and to identify problem areas; Steering function in order to set targets and give directions to desired outcomes; Controlling function in order to supervise process execution. Keywords: level of skill of staffs, Information communication and technology, Tendering systems and Performanc
Determinant Affecting Performance of Supply Chain Systems in the Petroleum Industries in Kenya
The purpose of this paper was to analyze the effect of crude oil price as a determinant on performance of supply chain systems in the petroleum industries in Kenya. Supply chain is a dynamic process and involves the constant flow of information, materials, and funds across multiple functional areas both within and between chain members. Members in the chain need to cooperate with their business partners in order to meet customer’s needs and to maximize their profit by reducing cost of crude oil. However, it is a very difficult task in managing the multiple collaborations in a supply chain because there are so many firms involved in the supply chain operations with its own resources processes also requires real-time operation and decision making across different tasks, functional areas, and organizational boundaries in order to deal with problems and uncertainties. The strategic move of focus for mass customization, quick response, and high-quality service cannot be achieved without more complex cooperation and dynamic structure of supply chains. Keywords: Cost of crude oil price, and Performance of supply chai
Finishing Effect on Fatty Acid Profile of Intramuscular Fat in Extensively Reared Steers
Both the amount and the composition of fat depots in beef may be influenced by several factors i.e. feeding system. Related to this factor, extensively reared cattle may produce beef with a more desirable fatty acid (FA) composition in terms of beneficial effect on human health, especially in relation to the content of n-3 type FAs. However, concentrate finishing improves some carcass traits and meat quality. In this sense, the objective of this work was to study the effect of concentrate finishing on intramuscular (IM) FA profile of Longissimus thoracis (LT) muscle in pasture fed steers
