Four experiments were conducted to investigate the effects of ultraviolet (UV) light exposure and several cholecalciferol metabolites on the development of tibial dyschondroplasia (TD) and other parameters associated with vitamin D metabolism in chickens selected for high (HTD) and low (LTD) incidence of TD. In Experiment 1, exposure of chickens to UV light reduced the incidence and severity of...

BACKGROUND The levels and immunohistochemical localization of muscle carbonic anhydrase III (CA-III) in healthy chickens and in muscular dystrophia affected (DA) chickens show that the muscles of diseased animal undergo a progressive increase of enzyme activity. METHODS An enzyme-linked immunoassay was used to assess the CA-III levels in the muscles and other tissues from eight normal White L...

Avian amyloid A (AA) amyloidosis is commonly observed in adult birds with chronic inflammation, such as that caused by bacterial infection. We previously described vaccine-associated AA amyloidosis in juvenile chickens. In this study, the prevalence of amyloid deposition was measured in mature healthy chickens that survived a previous outbreak of avian AA amyloidosis while they were juveniles. ...

Received: Revised: Accepted: June 13, 2014 July 19, 2014 August 05, 2014 The use of haematology as an index of health status is well known, just like the use of erythrocyte osmotic fragility and heterophil-lymphocyte ratio (H:L) as biomarker of oxidative stress. The aim of this study was to investigate the effect of molasses supplementation through drinking water on live weight gain, haematolog...

diversification of phosphorus sources can bring substantial synergy effects within all thesustainable development domains: environmental, economic and social, and such an opportunity should not beoverlooked. urban sinks accumulate phosphorus and other elements and may serve as sources of secondaryraw materials. this paper evaluates phosphorus sources based on their total material requirement (t...

Wheat (Triticum aestivum L.) was grown in earthen pots containing soil of Balkasar Soil Series (Sandy Loam) in green house at the Department of Soil Science and SWC, Pir Mehr Ali Shah Arid Agriculture University, Rawalpindi during Rabi season, 2007. The Crop was treated with two levels of Phosphorus (40 and 80 kg P ha-1 ) in the form of SSP, TSP, NP and DAP. A basal doze of 100 kg N and 60 kg K...

Background: This study aims to evaluate the efficacy of silybum marianum seeds (SMSs) on blood biochemical profile of broiler chickens contaminated with Aflatoxin B1 (AFB1).  Methods: Combinations of three levels of AFB1 (0, 250 and 500 ppb) with three levels of SMSs (0, 0.5, and 1.0 %) were incorporated into the basal diet (corn and soybean meal). The effect of nine experimental treatments was...

Introduction: Transportation causes stress in chicks that may make numerous physiological changes with a negative impact on their production and health. This study was conducted to examine the effects of injection of diazepam, melatonin, methocarbamol and glucose on Serum biochemical parameters include: glucose, total protein, albumin, uric acid, cholesterol, triglycerides, Ca, P, Zn, Fe, Na an...

In this study, the effects of malted sorghum-based diets (MSBD) on carcass characteristics and meat quality were investigated in broiler chickens. Two-week-old Ross 308 broilers randomly allocated to three groups (each with five replications) then reared either 0 or 100% (red (Mr Buster) white (Segaolane)) sorghum commercial diets. The highest (p < 0.05) slaughter weights, hot cold weights o...

Ruminal bacteria and protozoa provide excellent organic phosphorus (P) sources for the host animal. This experiment was conducted to compare the bioavailability of bacterial and protozoal P in comparison with that of dicalcium phosphate (DCP) as a reference phosphorus source. Bacteria and protozoa were isolated from the rumen contents of dairy cows and the chick-model was used to determine the ...
