This study is aimed at evaluating antibody responses, viral loads, clearance and growth rate of Tanzanian free-range local chicken (FRLC) challenged with LaSota strain Newcastle disease virus (NDV) as indicator traits for selection chickens breeding enhanced resistance to the economic value. Three popular ecotypes: Kuchi, Ching’wekwe Morogoro-medium from three ecological zones Tanzania we...

The experiment was carried out to investigate the effects of Christmas melon and Neem extract on growth performance, carcass characteristics, organ characteristics cost benefits broiler chickens. employed a completely randomized design. All data generated were subjected analysis variance. A total one hundred day old Abor Acre chickens used in this study, birds weighed arrival brooding pen know ...

The study ascertained the production practices of small-scale broiler farmers in Aguata Local Government Area Anambra State, Nigeria. A multistage sampling procedure was adopted for random selection 80 using a structured interview schedule. data were analysed descriptive statistics. result reveals that 87.5% deep litter housing system, and 98.75% ensured their poultry houses sited well-drained ...

Given a discrete-time random dynamical system represented by cocycle of non-singular measurable maps, we may obtain information on quantities studying the Perron–Frobenius operators associated to maps. Of particular interest is second-largest Lyapunov exponent for operators, λ2, which can tell us about mixing rates and decay correlations in system. We prove generalized theorem cocycles bounded ...

The aim of our study is to evaluate the effect Apsa-mos® as immunostimulant on level antibodies in broiler chickens vaccinated with Newcastle disease live attenuated vaccine (β1 and lasota strain) at 10, 24-day old respectively. Forty, one-day-old chicks were reared this experiment. They divide into four groups treated follows: Chicks 1st group control one (G1); 2 (G2), β1 NDV 10 days followed ...

Current control strategies for avian influenza virus, exotic Newcastle disease, and other highly contagious poultry diseases include surveillance, quarantine, depopulation, disposal, and decontamination. Skid steer loaders and other mobile equipment are extensively used during depopulation and disposal. Movement of contaminated equipment has been implicated in the spread of disease in previous ...

In the present study, we developed a novel approach for foreign gene expression by Newcastle disease virus (NDV) from a second ORF through an internal ribosomal entry site (IRES). Six NDV LaSota strain-based recombinant viruses vectoring the IRES and a red fluorescence protein (RFP) gene behind the nucleocapsid (NP), phosphoprotein (P), matrix (M), fusion (F), haemagglutinin-neuraminidase (HN) ...
