Abstract: Increasing heat stress threatens livestock production especially lactating dairy cows across the world. Therefore this study was conducted to evaluate the effect of heat stress on physiological parameters, adaptation and mitigation strategies of lactating Kereyu and Hararghe cattle breeds in Bordode District, Ethiopia. Purposive sampling technique was used to select study area and respondents and Bordode district was selected based on the availability of both Kereyu and Hararge cat...
Abstract: This study was conducted to evaluate the effect of water restriction on physiological and blood parameters of Afar rams under arid climatic condition at Kalu District, Southern Wollo Zone, Amhara Regional state, Ethiopia. Eighteen healthy, 1.5 years old and 23-24 kg of live weight afar rams were randomly assigned in to three water restriction treatment groups with six rams each. The experiment was conducted during 4 seasons (viz. dry and wet season and the tests were carried out ov...
ABSTRACT Hylomyscus denniae endorobae is a rodent important in ecosystems as predator, prey, seed disperser, determinant of forest tree growth and structure as well as a contributor to biodiversity which subsequently plays a role in natural livelihood and national development. Fragmentation of tropical rain forest continues to pose a serious threat to species diversity, which leads to decreased natural income, primary production and general breakdown of an ecosystem. This in turn influences ...
ABSTRACT River Ruiru flows in areas where it is subject to pollution due to industrial, municipal, urban and agricultural wastes. It is reported to harbor various species of fish such as tilapia, catfish, eel, and common carp, which may be contaminated by heavy metals present in such wastes. Metals damage fish organs, endangering the species inhabiting the river. In addition, when other organisms, including humans consume such fish, they are exposed to heavy metal contamination. Hence, it is ...
ABSTRACT The Nile tilapia, Oreochromis niloticus, is a tropical fish species of commercial importance in both aquaculture and in the wild. It plays a great role in human nutrition and food security. Industrial effluents, contaminated with pollutants such as heavy metals are released into water bodies such as streams and rivers, in most countries. River Ruiru is one of the rivers faced with pollution from nearby industries. It is inhabited by various species of fish such as catfish, tilapia a...
ABSTRACT Rodents are the greatest vertebrate pest problem in developing countries causing substantial damage to structures, food, crops, industrial and domestic property. They also act as reservoirs and vectors of zoonotic diseases. The current method for controlling rodents is the use of rodenticides which are toxic to non target organisms, pollutants to environment and trigger resistance. In an effort to find eco-friendly alternatives to synthetic rodenticides, reproductive inhibition of Ri...
ABSTRACT The worldwide prevalence of erectile dysfunction (ED) in 1995 was estimated to be 152 million males, and the figure is expected to rise to 322 million by the year 2025. The inability to achieve or sustain an erection and/or an inability to ejaculate is common among men over 40 years, where about 5% will experience ED and rates increase with age. Pomegranate (Punica granatum L.) has traditionally been believed to be of importance in male sexual disorder management. This investigation ...
Abstract African animal trypanosomosis (AAT) or Nagana is a transboundary disease with immense negative impact in Agricultural development across 37 African countries, with 60M livestock at risk. Utilization of trypanotolerant breeds as a form of control may offer a viable and sustainable option following recent identification of nine trypanotolerant quantitative trait loci (QTL) with positive effects in an F2 cattle population ofN'DamaJ Kenyan Beran, under a challenge of 1180 clone of Tcongo...
