Abstract. Setyowati EA, Santoso S, Rokhmani, Rochmatino. 2022. Diversity and prevalence of endoparasites in domestic chickens across an elevation gradient. Biodiversitas 23: 3936-3942. The chicken farm is negatively affected by endoparasites, which decrease immunity, egg production, body weight. Although these effects are well understood large-scale farms, here we aimed to understand endoparasi...

Infection of animals with retroviruses frequently leads to immunosuppressed states. The immune status of chickens injected with the replication-defective avian erythroblastosis virus (AEV), with its naturally occurring subgroup B helper virus (avian erythroblastosis-associated virus; AEAV), was evaluated daily and compared to the immune status of age-matched uninfected control chickens. Spleen ...

The presence of Salmonella in chickens is a problem because poultry meat is recognized as a source of human salmonellosis. Fermented feed has characteristics like a high number of lactobacilli and high concentration of lactic acid, which could make chickens less susceptible for infection with Salmonella. Fermented feed might therefore prevent the colonization of chickens with Salmonella. Two st...

The studies were based on the RAPD fingerprinting for the species identification of animals. The genomic DNA samples of ostriches, Taiwan local chickens, Aboracres broilers, Leghorn chickens, quails, doves, emus, Beltville small white turkeys, pheasants, Chinese geese, mule ducks, Holstein cattle and Landrace pigs were amplified with random primers by RAPD-PCR for fingerprinting. The results sh...

Indigenous Tswana chickens are better adapted to prevailing environmental conditions and diseases than their exotic counterparts. They however exhibit slower growth rate and less mature final weight than their exotic counterparts. Crossbreeding of indigenous Tswana chickens with exotic chicken breeds can therefore be used as an alternative strategy to improve growth performance of indigenous Ts...

AIM This research was conducted to determine the most affecting parameters on hatchability of indigenous and improved local chickens' eggs. MATERIALS AND METHODS Five parameters were studied (fertility, early and late embryonic mortalities, shape index, egg weight, and egg weight loss) on four strains, namely Fayoumi, Alexandria, Matrouh, and Montazah. Multiple linear regression was performed...

Indigenous chickens (IC) are mainly raised by resource poor rural households in developing countries [1]. Although they are of low genetic potential compared to the commercial breeds, IC play a vital role in livelihoods of farmers and contribute significantly to food security and income [1]. IC dominates in most smallholder farms in Malawi and they are deemed less productive but appear to be ad...

Introduction: As a valuable genetic resource, native birds can contribute to the sustainable development of animal production. Tibetan chickens, known for their special flavor, are one important local poultry breeds in Qinghai–Tibet Plateau. However, chickens have slow growth rate and poor carcass traits compared with broilers. Although most research on focused hypoxic adaptation, there were fe...

Low-fibre sunflower residue (SFR) included in the diet is a viable option for improving production in smallholder-owned poultry. Four hundred day-old broiler chicks (200 hybrid + 200 village chicks) were given broiler starter (1-28 days) and a low-fibre sunflower residue diet (29-84 days). On day 29 the chicks were randomly allocated to four treatments (2 types of chicks, 2 systems of housing):...
