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...

Three experiments were conducted to determine the effects of pelleting and extrusion of feeds on the utilization of phytate P by broilers. The first experiment investigated the effects of pelleting the whole corn-soybean meal (SBM) diet, the corn, or SBM separately on phytate P utilization. The P-deficient basal diet contained 0.5% total P and 0.2% phytate P. Steam pelleting the whole diet, the...

BACKGROUND: Increasing of oxygen consumption in fast-growing broiler chickens is associated with the more pronounced occurrence of right ventricular hypertrophy and ascites. While, rearing of susceptible chickens in dark condition could reduce the metabolic rate of birds and hence the incidence of ascites. OBJECTIVES: The present study was designed to investigate a comparative study on the inf...

Fulani ecotype chickens (FEC) and Yoruba ecotype chickens (YEC) are the two major types of indigenous chickens in Nigeria. They subsist under traditional Animal husbandry and are thus liable to indiscriminate mating and consequently to loss of genetic diversity. Fulani ecotype chickens (FEC) and Yoruba ecotype chickens (YEC) were investigated to determine genetic variation at transferrin locus ...

Nowadays, nanoparticles (NPs) have the great potential application in different industries. Among all NPs, titanium dioxide NPs is the biggest ecotoxicological and ecophysiology concerns due to the increase of anthropogenic input into the aquatic ecosystems. In this study, the effects of titanium dioxide NPs enriched yeast on the growth, survival; digestive enzymes activity and lipid metabolism...

The aim of the present experiment was to study the growth hormone (GH) response upon thyrotropin releasing hormone (TRH) challenge (2 micrograms/kg body weight) in broiler chickens selected for body weight gain (GL line: fat line) or for feed efficiency (FC line: lean line) reared at either a moderate (33-23 degrees C) or high (33 degrees C) ambient temperature. A higher plasma GH level at 5 mi...

Background: Toxoplasma gondii, as an important food-borne protozoan parasite, occurs widely in humans and animals including domestic poultry throughout the world. The goal of this survey was to determine prevalence rate of T. gondii in free-ranging chickens sold in Tunis, Tunisia. Methods: In the present study, the prevalence of T. gondii in 40 free-range chickens (Gallus domesticus) marketed ...

This study aimed to evaluate how different percentages of guar meal in feed rations for broiler chickens affect their rearing performance and carcass composition. The experiment was conducted a group one hundred sixty Ross 308 broilers randomly allocated four equinumerous groups (K, G4, G8 G12). birds were reared over 42 days with the application three feeding periods: starter (days 1–21), grow...

Previous studies using zearalenone (ZEN) and fumonisins (FB) revealed alpha-zearalanol (?-ZOL) FB1 in the liver of turkeys chickens with no sign toxicity. The aim present study was to determine whether contamination persists after distribution a mycotoxin-free diet for several days. Turkeys broilers were fed 14 days containing respectively, 7.5 0.6 mg/kg FB ZEN, then 0, 2 or 4 diet. total ?-ZOL...

Experimental infection of Muscovy ducks with V4 strain of Newcastle disease virus was undertaken to determine the response of the ducks to the virus and the possibility of virus transmission to ducks and chickens in village like conditions. Twelve ducks were randomly and equally divided into three groups of control, inoculated and in-contact. Additionally, the chickens were placed into two grou...
