Effect of Gestation and Season on the Haematological and Biochemical Parameters in Domestic Rabbit (Oryctolagus cuniculus)
No full textThe aim of this study was to investigate the effect of gestation and season on the haematological and biochemical parameters in domestic rabbit (Oryctolagus cuniculus) to improve the conditions of breeding and conservation in Saudi Arbia. For this study. 30 non-pregnant and 30 pregnant rabbits on day 24 to 26 of gestation were examined. The animals weighed between 2.6 and 3.6 kg and were 1.8-2.6 years old. Blood samples were collected from pregnant and non–pregnant rabbits in January (winter season), April (spring season), July (summer season) and October (autumn season) for analyzing hematological and biochemical parameters. It was revealed for the study that the value of hematological parameters i.e., erythrocyte, leukocyte, lymphocyte numbers and haemoglobin concentrations of pregnant rabbits were significantly (p<0.05) decreased compared with non-pregnant rabbit. Whereas, mean corpuscular volume was significantly (p<0.05) increased in pregnant rabbits compared with non-pregnant ones. The value of biochemical parameters i.e., total protein, albumin, triglyceride, cholesterol, calcium, and phosphorus were significantly (p<0.05) decreased in pregnant rabbits compared with non-pregnant. Whereas, glucose level was significantly (p<0.05) increased in pregnant rabbits compared with non-pregnant rabbits. Most of hematological parameters significantly (p<0.05) decreased in July. In contrast only few significant changes recorded in biochemical parameters. In conclusion, the rabbits suffer of heat stress during summer season and this causes deterioration in some, hematological constituents and biochemical parameters. These changes can be reflected on the activities, performance and fetus of pregnant rabbits under hot environmental conditions of Saudi Arabia. Hence, it can be concluded that winter is the best season for breeding and conservation of domestic rabbits
Studies on Cyanobacterial Biodiversity in Paper Mill and Pharmaceutical Industrial Effluents
No full textA thorough knowledge of the physical, chemical and biological characteristics of an industrial waste is a crucial requirement for any attempt at chemical and/or biological treatment of the waste. Hence the present study was aimed to assess the physicochemical characteristics and cyanobacterial study on different industrial effluents. In the present study, effluents from two different places, paper mill and pharmaceutical industries, were selected to determine the cyanobacterial biodiversity. It was revealed that the physicochemical characteristics of both effluents studied were more or less similar. Total 25 species of cyanobacteria were found to be distributed in two different effluents in which twenty two were found in paper mill and fourteen were in pharmaceutical industries. Some of the species of cyanobacteria like Microcystis aeruginosa, Oscillatoria curviceps, O. princeps, Phormidium ambiguum, P. corium and few more were recorded in both the effluent analyzed. The dominant genus was recorded to be Oscillatoria and among themselves its six species were recorded. The abundance of cyanobacteria in these effluents was due to favorable contents of organic matter, rich calcium and nutrients such as nitrates and phosphates with less dissolved oxygen. Therefore, it can clearly stated that physicochemical characters together with biological monitoring of industrial effluents provided converging lines of evidences for evaluation of polluted habitats in this case as in some other studies reported by many researcher. This type of study would be valuable for future pollution abatement programmes
