The study involved survey to assess dairy cattle management practices, retrospective study to evaluate the efficiency of AI service, and field monitoring to confirm the retrospective study. A total of 128 households (64 AI beneficiary and 64 AI non-beneficiary households) were selec...
Abstract: The overall objectives of this dissertation were to improve access to improved/selected bucks by farmers of the research sites and to contribute to their food security and income improvements. The specific objectives were: 1) to present reliable genetic parameter estimates based on meta-analysis of literature reports; 2) to evaluate production and productivity of three indigenous goat breeds in Ethiopia namely Abergelle (AB), Central Highland (CH) and Woyto-Guji (WG) and have bench...
Abstract: The study was conducted in the Konso Zone of southern Ethiopia to Evaluate the Community Based Breeding Program (CBBP) on Woyto-Guji (Konso) goat breed. A total of 1984 birth weight (BW), 1663 three-month weight (3MW), 1411 six-month weight (6MW), 1133 nine month weight (9MW), and 987 twelve-month weight (12MW) records were used for the analysis of non-genetic and genetic factors affecting growth traits. The least-square means analysis was performed using the general linear model p...
Abstract: This study was carried out to estimate genetic parameters and to evaluate non-genetic ef ects on milk production and reproductive performance of Jersey cattle via an animal model by using variance component estimation VCE-6 version 6.0.2 & PEST 4.2.5 and SAS software (2016) version 9.4 the GLM procedure. The data was obtained from a state farm, located in South Ethiopia, Woliata Sodo, Ethiopia. The least-square mean value of production traits such as Daily Milk Yield (DMY) and Lact...
Abstract: This study was conducted to assess the breeding practices and to evaluate AI efficiency after estrus synchronization in dairy cattle in Lemo and Misha districts. The study was conducted at two agro-ecological zones Misha (highland) and Lemo (mid-altitude). Data were collected using semi structured questionnaire and focus group discussion. A total of 120 respondents were randomly selected from the two districts (60 from each) and 6 kebeles (3 kebeles each and 20 household from each ...
Abstract: Questionnaire survey from 144 households and physical measurements from 510 animals were done to characterize production system and phenotype of the Begait sheep breed in two districts of Tigrai regional state. Reconnaissance tour, focus group discussion, semistructured interview, field observation, secondary data and linear body measurements were used to generate the dataset and analyzed using SPSS V20 and SAS V9.1 for the survey and linear body measurements respectively. The stud...
Abstract Twenty-five intensively managed mature West African Dwarf goats were used for the experiment comprising 20 Does (dams) and 5 bucks (sires). The goats were classified into 5 mating pens of 4 Does (dams) and one buck (sire) randomly assigned per pen. Fresh water and forage were provided ad libitum in addition to 1kg concentrates Cajanus cajan to each animal per day. Data were collected on weights at birth and weaning; litter size and linear body measurements. Body weight gain was cal...
ABSTRACT Two experiments were conducted to determine the effect of frequency of semen collection and management systems on semen quality, fertility and hatchability of local turkeys in the humid tropics. A total of 72 local Nigerian turkeys comprising 24 males and 48 females were used for the study at 36 weeks of age with average body weight of 9kg for the males and 4kg for the females. The males were randomly divided into two groups (1 and 2) with 12 males in each group. Group 1 males were i...
ABSTRACT The present study was carried out to evaluate genetically the growth performance of the Gudali and Wakwa beef cattle. Data utilized for this study was obtained from the Institute of Agricultural Research for Development (IARD), Wakwa Station, Cameroon. The data used consisted of pedigree information of 3788 animals and 2276 performance records for the Gudali and Wakwa cattle respectively, ranging from birth to 36-months weight collected from 1968 and 1988. The data were collected fro...
ABSTRACT Gulella taitensis is a land snail of the family Streptaxidae and genus Gulella. It is endemic to Taita hills and categorized as endangered on the IUCN Red List. The species is threatened by habitat loss and disturbance due to human activities. Two people sampled snails at four sampling plots using standard timed direct search for one hour. Soil samples were collected from four different points within these sampling plots, and its pH, calcium and electrical conductivity obtained using...
ABSTRACT Indigenous chicken are a valuable asset and form an integral part of many households in Kenya in terms of food security, economic and social roles. Given their value to the agricultural sector, various interventions are being developed and implemented to realize their potential in the sector. Such interventions involve genetic improvement of production traits which directly translate to increased revenues. However, this is likely to be accompanied with increased inputs, especially fe...
A deterministic bio-economic model that incorporates risk for pasture-based dairy cattle production in the tropics was developed. Two production circumstances were considered: fixed pasture (FP) and fixed herd size (FH). In each circumstance, efficiencies (both economic and biological) and profit were calculated based on milk marketing on volume, and on volume and butter fat content. Additionally, a profit function was used to estimate risk-rated profit(s) where the intensity of the farm...
