Dietary Supplementation of Chromium Chloride and Ascorbic Acid to Alleviate the Negative Effects of Heat Stress in Broiler Chicks

This study was conducted to investigate the effects of diets supplemented with chromium chloride, CrCl3.6H2O (20 mg/kg basal diet), ascorbic acid, AA (1000 mg/kg basal diet) or their combination on the physiological performance and immune response of broiler chicks raised under summer conditions (31.5-34.5ºC). Dietary supplementation of AA or the combination of AA and CrCl3 resulted in a...

Seasonal Variations In Blood Constituents And Milk Composition Of One-Humped Camel (Camelus Dromedarius)

The present study has been conducted in order to investigate the seasonal variation as well as the effect of age and sex on certain blood constituents in the one-humped camels (Camelus dromedarius). Furthermore, the seasonal variation in the milk composition and the botanical and chemical composition of plant parts consumed by camels were investigated. The study has been conducted on 210...

Effects of Nutritional and Environmental Factors on Physiological Responses and Semen Characteristics of Desert Rams

The studies were conducted to investigate the effects of certain nutritional and climatic factors on thermoregulation, blood composition and semen characteristics of Desert rams .The experimental design included evaluation of the effects of lowering the level of feeding Lucerne hay to 66% (medium) and 33% (low) at libitum level on thermoregulation, blood metabolites and semen characteristics...

Physiological Responses Of Nubian Goats To Haemorrhage As Affected By Bleeding Level , Age And Splenectomy

The studies were performed to investigate the effects of bleeding level, age and splenectomy on physiological responses to haemorrhage in goats. In experiment 1, the effects of two levels of bleeding (15% and 30%) were evaluated in adult goats. The magnitude of haemorrhage was expressed as percentage of initial total blood volume after plasma volume determination by dye dilution .The groups...

Effect of Salinity of Drinking Water and Dehydration on Thermoregulation, Blood and Urine Composition in Nubian Goats

The studies were performed to investigate the effects of salinity of drinking water, state of body hydration and seasonal changes in the tropical thermal environment on physiological responses of Nubian goats. In experiment 1, the effects of salinity of drinking water (0.8, 1.2, 1.6, and 2% NaCl) on physiological responses of Nubian goats have been investigated in winter and summer. Tr was not...

The Performance and Thermal Responses of Exotic Breeds of Laying Hens under Hot Climate

Three experiments were carried out on two exotic breeds of laying hens (Bovan and Hisex White) to evaluate their performance during the rearing and production periods under tropical conditions. Birds were caged randomly, in open-sided poultry house in Shambat (Department of Physiology, experimental Farm). The chicks were fed on isocaloric isonitrogenous (chick and grower) feed during the...

Effects Of Thyroid Status And Thermal Environment On Physiological And Immunological Responses In The Domestic Rabbit (Lepus Cuniculus)

The studies described in this thesis were performed to investigate the effects of thyroid status and thermal environment on physiological and immunological responses in male domestic rabbits. In experiment 1, the effects of subcutaneous administration of sodium L-thyroxine, T4 (10, 20 and 30 ƒفg/kg BW/day) were evaluated. The groups receiving T4 had higher rectal temperature (Tr), respiration...

Effect of Dietary Zinc Bacitracin on Broiler Chicks Performance and ‎Physiological Responses under Summer Conditions ‎

Two experiments were conducted to investigate the effects of ‎subtherapeutic dose levels of zinc bacitracin (ZnB) on physiological ‎responses and performance in broilers chicks under wet and dry tropical ‎conditions of Sudan.‎ Increasing the levels of ZnB resulted in a progressive significant increase ‎in average final body weight (P < 0.01), average total weight gain (P < ‎‎0.01), average...
