This study aimed to evaluate various selection strategies for adoption in dual-purpose (ICD), meat (ICM) and layer (ICL) breeding goals indigenous chicken programs. The ICM goal improve live weight (LW

Summary Development of the livestock industry and its role in poverty alleviation developing countries depends on how adaptive production systems are to changing global environmental economic trends. This paper characterizes dairy India, Tanzania, Kenya Nicaragua, describes genetic breeding technologies that hold promise for advancement development goals. The value chain has been prioritized under CGIAR research programme Livestock Fish Tanzania (East Africa), India (South Asia) Nicaragua...

This paper presents a review of dairy goat production in sub-Saharan Africa (SSA) from 2010- 2017, its current state, constraints and prospects for research development. Since the introduction goats SSA pre-colonial times, their populations have continued to increase due declining land size as result fragmentation increasing demand milk. The population is 372,716,040 head which only 15.98% used milk production. Populations Eastern Western regions shown an trend 2010 2017. Southern on decline...

Genetic improvement of farm animals encompasses both mating and selection for desired traits indigenous chicken genetic resources are no exception. In Kenya, previous attempts to genetically improve involved cross-breeding scheme by utilizing cockerels pullets exotic breeds with the local chicken. This was complimented farmer training on good management practices vaccination disease control. The partially successful improved performance in crossbreds that declined subsequent generations....

Most of Kenya (80%) is classified as arid and semi-arid. The climatic conditions in these regions are so harsh for crops that only livestock production can thrive. These provide the bulk beef consumed country, which produced via two main systems: large-scale dairy-meat commercial ranching small-scale production. In both systems, pasture-based. animals kept highly adapted indigenous zebu (small East African Boran) or exotic (for example, Hereford, Simmental, Charolais, Angus) breeds their...

The objective of this study was to describe the lactation curve dairy cattle in Kenya using a suitable function order facilitate inclusion partial lactations national evaluation and assess effect data characteristics on parameters. Six functions were fitted test day (TD) milk yield records from six parities Ayrshire, Guernsey, Holstein Friesian, Jersey Sahiwal cattle. Five datasets: DS-1 (12-TD dataset with randomly missing records), DS-2 (10-TD without DS-3 DS-4 (7-TD dataset, only TD 4 10...

This study aimed at estimating genetic and phenotypic relationships among feed efficiency, immune production traits measured pre- (9–20 weeks of age) post- (12 from on-set lay) maturity. Production were average daily gain (ADG) feed-intake (ADFI 1 ) in the pre-maturity period age first egg (AFE), 2 mass (EM) post-maturity period. Feed efficiency comprised residual intake (RFI) estimated both periods. Natural antibodies binding to keyhole limpet hemocyanin (KLH-IgM) specific Newcastle disease...

In Kenya, selection of dams for the national contract mating scheme is based on 305-day lactation milk yield (TMY) performance across parities. At farm level, only cows that had good TMY in previous parity are retained subsequent lactation. This strategy has resulted improved production performance, although increased incidences physiological disorders, mastitis and reduced fertility have been reported high-yielding cows. Records functional traits relative to scant. Properties curves could...

Climate change (CC) impedes smallholder dairy industry in Kenya. Consequently, farmers’ adaptation to CC effects would greatly determine their resilience, profitability, and sustainable contribution the economy. Socio-demography among other factors, adaptive strategies effects. This study sought understand how farmers South Western Kenya adapt climate changes relationship between famers’ socio-demographics of sex, age, marital status, highest educational level, household size, experience...

SUMMARY Animal recording is an interactive process that involves several practices. The efficiency of the essential to ensure utility outcomes necessary for sustainable participation. Most evaluation approaches define in economic terms. systems lack outputs direct benefits; hence, based on derived from records would be more laudable. In case, a system considered efficient when outcome-utility-dependent participation sustained. Approaches evaluating are, however, unavailable. current study...

Interest in both dairy and meat goat production the US has been increasing, there is tremendous opportunity for genetic progress traits that are easy to measure (e.g., milk yield) those more difficult residual feed intake, RFI). However, little research or infrastructure within industry implementation of large-scale evaluation. The objective this study was conduct a genome-wide association (GWAS) RFI total yield goats. Forty-eight Alpine females (56.4 ± 7.15 kg BW; 423 146.1 milk; 225 20.9 d...

Despite great potential, Kenyan smallholder dairying faces diminishing land sizes, high input costs, poor extension contacts, non-responsive price policies, and new pests diseases. Climate change will worsen the situation. This study sought to assess dairy farmers' climate adaptation level in Southwestern Kenya. Adopting Concurrent Fixed Mixed Methods, primary secondary data was collected. Reports papers were reviewed for temperature precipitation data, population, production trends,...

This study aimed at investigating the influence of genetic and non-genetic factors on immune traits to inform possibilities improvement disease resistance in local chicken Kenya. Immune such as natural specific antibodies are considered suitable indicators an individual's health status consequently, used indicator resistance. In this study, binding Keyhole Limpet Hemocyanin (KLH-NAbs) was measure general Specific Newcastle virus (NDV-IgG) post vaccination Titers KLH-NAbs isotypes (KLH-IgM,...

Indigenous Chicken (IC) keeping in Kenya is predominantly based on an extensive system that characterized by high mortality rates, resulting mainly from disease outbreaks and predation. Information farmers' risk attitudes scarce despite the risks inherent IC production systems. Similarly, it unclear how socioeconomic factors influence their productivity. As a result, understanding of determinants attitude effects productivity are critical. Primary data were collected using structured...

This study was conducted to determine the growth patterns of Kuchi ecotype chicken in Kenya. Data obtained from intensively reared birds at Indigenous Chicken Improvement Programme (INCIP) facility Egerton University. Gompertz's nonlinear model fitted longitudinal data predict live body weight various age points and curve parameters. Growth rate maturity parameters for all ages were calculated using The inflection parameter including (TI), (BWI), (GI) also Males had significantly (P < 0.05)...
