Assessment Of Water Quality And Fish Producivity In Three Undrainable Reservoirs Of Naromoru, Nyeri County, Kenya

AbstractNaromoru is a semi-arid area located on the leeward side of Mt. Kenya, and has more than 15 small sized reservoirs constructed to provide water for livestock, irrigation and domestic use. To increase their usefulness, some reservoirs have been stocked with fish, even though no studies have been carried out to establish their suitability and potential for fish culture. This study therefore aimed at assessing the water quality, fish food availability and fisheries productivity of three ...

Distribution And Vegetation Association Of Grevy’s Zebra (Equus Grevyi) In Tsavo East National Park And The Surrounding Ranchlands

ABSTRACTGrevy’s zebra (Equus grevyi), the world’s largest wild equine, is endemic to the arid Horn of Africa. Originally, its range extended throughout the Horn of Africa but currently it is found only in Kenya and Ethiopia. The population has declined from 15,000 in the late 1970s to between 1,964 and 2,445 animals by the year 2008. The population declines as report by William and Low (2004) is probably as a result of being killed for meat, medicinal purposes, loss of access to critical ...

A Genetic Approach To The Management And Conservation Of The Hartebeest (Alcelaphus Buselaphus) In Kenya

ABSTRACT A lot of effort is put on 'proximate' threats to conservation, overlooking the 'ultimate' conservation goals in the process. Ultimately, attempts need to be made to conserve not just individuals or populations, but processes that have been on-going over vast geographical space and long evolutionary time, such as gene flow and natural selection. So far, little is known about these historical processes that decisions affecting the management of species in fragmented landscapes ar...

Effects Of Land Use And Seasonality On The Distribution Of Mayflies And Water Quality Along Thika River, Kenya.

ABSTRACTMayfly order (Ephemeroptera) is a widely distributed taxon that is used commonly in the biological assessment of water quality due to its sensitivity to changes in water quality. Despite its values in water quality assessment, studies on the taxa are still very scanty in most tropical countries, including Kenya. Water quality deterioration remains a vital threat in most rivers. The primary objective of this study, was therefore to investigate the spatial and temporal changes in commun...

Amino Acid Reference Values For Selected Feedstuffs Used In The Nigerian Poultry Industry

ABSTRACT The main objective of this study was to establish reference protein composition values for selected local feedstuffs such as dry brewers spent grain (DBSG), cassava meal (CAM), palm kernel cake (PKC) and groundnut cake (GNC) for the Nigerian feed industry by determining amino acids profiles and amino acids compositional quality scores. The selected local feedstuffs were each sourced from five locations from northern and southern parts of Nigeria such that there were five sample...

Effects Of Dietary Selenium Supplementation On Reproductive Performance Of Sows

ABSTRACTThis study was conducted to investigate the effect of dietary selenium (se) supplementationon the reproductive performance of sows, preweaning growth performance of their piglets,haematological and antioxidant status of pigs. Twelve (12) crossbred sows (Landrace × LargeWhite) aged 1-2 years with an average body weight (BW) of 56.1 ± 5kg were randomlyallotted to four treatment groups of three sows per treatment in a completely randomiseddesign (CRD). The treatment groups comp...

Performance, Bone Mineralization And Haematological Indices Of Broilers Fed Phytogenic Feed Additives

ABSTRACTA 35-day experiment was carried out in a completely randomized design to determine theefficacy of two phytogenic feed additives as veritable alternatives to antibiotics using 320 dayoldunsexed commercial Ross 308 broiler chicks. The chicks were randomly divided into fourgroups of 80 birds each and assigned to four isocaloric (12.60, 13.2 and 13.4 MJ/Kg AMEn) andisonitrogenous (25.0, 22.5 and 20.07 % CP levels) diets designated as follows: diet 1- maizesoybeanbased diet witho...

Effects Of Dietary Vitamin C And Vitamin E On The Performance Of Laying Hens In The Humid Tropics

ABSTRACTThis study which lasted for 52 weeks investigated the effects of dietary Vitamin C (Lascorbicacid) and Vitamin E (dl- alpha tocopheryl acetate) on the performance of layinghens in the humid tropics. A total of 240 twenty-four week old Golden Neslink pullets wererandomly selected from a flock of 550 birds and randomly divided into sixteen treatments of15 pullets. The birds were initially vent examined to ensure that they were at point of laybefore commencing the study. Each pulle...

Evaluation Of Forage Sweet Potato Cultivars As Feed For Ruminants

ABSTRACT There is potential in Kenya to utilize forage sweet potato (Ipomoea batatas (L) Lam) cultivars as livestock feed. There are many cultivars of forage sweet potato in Kenya whose feeding values have not been evaluated. The objectives of the current study were: 1) evaluate forage sweet potato cultivars for crude protein (CP) yield and digestibility at different harvesting ages, 2) evaluate their conservation potential as silage or hay and 3) determine sheep growth performance and g...

Biochemical And Molecular Identification Of Key Pathogens Causing Mastitis In Dairy Goats On Smallholder Farms In Kenya

ABSTRACT Mastitis in dairy goats was investigated with the objective of establishing the effect of management and the identification of the key causative agents through common diagnostic procedures of somatic cell counts, bacteriological identification and, for the first time in goat mastitis, by use of Polymerase Chain Reaction. A cross-sectional survey, using a structured questionnaire was conducted in three agro-climatic regions of Coast, Nyanza and Rift Valley, with goat keeping clu...

Assessing Farm Level Practices Affecting Milk Production, Quality And Postharvest Losses In Smallholder Dairy And Pastoral Camel Herds Of Kenya

ABSTRACTFarm level post harvest milk losses (PHL) in smallholder and pastoral milking herds that occur at milking, pooling, evening storage or at the farm gate delivery may be associated with many farm practices. This study tested the hypotheses that PHL results from milk hygiene practices, that feeding practices influence production and quality of milk, and that milk market outlets influence milk hygiene and PHL. Data was obtained in cross sectional survey, on-farm milk and feed sampling for...

Influence Of Nutritional Metabolites And Hormonal Profiles On Reproductive Performance Of Lactating Cows

ABSTRACTNutrition influences postpartum ovarian activity but the effects of pre and postpartum feeding on metabolte and hormonal changes and their subsequent influence on reproductive performance remains unclear. This study attempted to explain effects of nutrition on these changes and their ultimate impact on reproductive performance of lactating cows. Forty in-calf cows comprising 20 Friesians and 20 Sahiwals were randomly assigned to 5 dietary groups of 4 cows per breed. Upon calving, cows...

Development Of Multi-Objective Ration Formulation Program To Optimise Feed Millers, Dairy Producers And Policy Regulatory Goals

ABSTRACT Dairy ration formulation in Kenya is currently based on the singular objective of least cost (LCF) that only considers cost to the economic advantage of feed millers. The interest of dairy producers is milk profit above feed costs while regulatory authorities are interested in feed quality standards and environmental health. Industry stakeholder interests on feed processing and utilisation and critical feed formulation goals present challenges to sustainable dairy productio...
