    Sahiwal cattle in semi-arid Kenya: genetic aspects of growth and survival traits and their relationship to milk production and fertility
    (2011-12) Ilatsia, E.D.; Migose, S.A.; Muhuyi, W.B.; Kahi, A.K.
    The aim of this study was to estimate genetic and phenotypic parameters for growth and survival traits of Sahiwal cattle in Kenya and determine their relationship to milk production and fertility. Performance records of 5,681 animals were obtained from the National Sahiwal Stud and the traits considered were: birth weight (kilogrammes), weaning weight (kilogrammes), pre-weaning average daily gain (grammes per day), post-weaning average daily gain (grammes per day), yearling weight (kilogrammes), mature weight at 36 months (kilogrammes), pre-weaning survival rate (SR), post-weaning survival rate (PSR), lactation milk yield (kilogrammes), age at first calving (days), and calving interval (days). The data was analysed using univariate and bivariate animal model based on restricted maximum likelihood methods, incorporating all known pedigree relationship among animals. The additive direct effects were more pronounced than maternal genetic effects in early and in post-yearling growth performance. The additive genetic variance and heritabilities were low for SR and PSR. The correlation between direct additive genetic and maternal genetic effect were negative for pre-yearling traits. Genetic and phenotypic correlations among growth traits and between growth and milk yield were positive, whilst those between growth and fertility were weak and negative. Correlations between survival and growth were generally low and positive. The estimates obtained in this study provide the necessary technical parameters for evaluating alternative breeding programmes and selection schemes for sustainable improvement of Sahiwal cattle.

    Staff Profile - Dr. Salome Atieno Migose
    (University of Embu, 2015-07) Migose, S.A.
    Dr. Migose is an alumnus of Wageningen University of the Netherlands where she attained her PhD in Livestock Production Systems, since 2020. Dr Migose did her MSc. in Animal Science (Animal Breeding option) and BSc in Animal Sciences at Egerton University, Njoro, Kenya. In 2012, she was a beneficiary of the fellowship from the Netherlands Organization for International Cooperation in Higher Education (NUFFIC) under a collaborative project between Egerton University and Wageningen University titled “Competent graduates for enhanced competitiveness in the dairy value chain” under the Netherlands Initiative for Capacity Development in Higher Education (NICHE-KEN-127). Her PhD study focused on understanding smallholder farming systems to improve dairy development in Kenya. Results of her work were presented at the 66th Annual meeting of European Federation of Animal Production (EAAP) in 2015, at Tropentag in 2015 and at the Wageningen Institute of Animal Sciences (WIAS) Science day in 2019. Two manuscripts related to the chapters of her PhD thesis are published and two manuscripts are submitted to peer-reviewed scientific journals. Dr Migose has gained much experience in training, research and extension in livestock production over the last 15 years. Prior to joining the University of Embu where he has been for the past 8 years, Dr Migose was involved in livestock extension while working at Livestock Recording Centre (LRC) of the Ministry of Agriculture Livestock and Fisheries, in projects such as east African agricultural productivity project (EAAPP), a collaborative project between the ministry and KARI (now KALRO) particularly in developing the productivity of dairy cattle through registration, recording and genetic evaluation. Dr Migose continues to network with Ministry of Agriculture, KALRO, ACTS, Performeter, and Sasini, among others. She is supervising one PhD and three Msc students in various projects among them identifying resilient livestock breeds and feed technologies for climate smart production systems for the Kenyan highlands and ASALs, under the KCSAP scholarship among others. She also provides mentorship to undergraduate students. She is involved in community outreach and extension activities with like-minded partners such as CARITAS. Besides, she is the chair of the livestock management sub-committee of the University farm, an Online and Distance Education and eLearning (ODeL) champion, and a member of the University Income generating projects (IGA) committee. Research Interests Livestock Production Systems, Animal breeding, animal feeds and feeding, livestock value chains, and matching breeding and feeding practices with production systems, climate change, sustainable food systems.
