Ectoparasitism has a damaging impact on the economy of goat production in India, but the factors influencing its distribution and dynamics are less explored. The present study was designed to investigate the influence of environmental factors like weather and air quality parameters on the occurrence of different types of ectoparasites in goats of two agro-climatic regions of India, viz. the Upper Gangetic Plain (UGP) and the Western Himalayas (WH). The prevalence survey for ectoparasitism among goats was conducted during the four distinct climatic seasons (winter, summer, monsoon, autumn) in both regions. The season-wise data of weather parameters (maximum and minimum temperature, relative humidity in morning and evening, sunrise and sunset time, mean daily temperature and relative humidity, daily variation in temperature and relative humidity, and day length) and air quality parameters (air quality index (AQI), particulate matter 2.5 μm (PM2.5), particulate matter 10 μm (PM10)) of both regions were analyzed in relation with the ectoparasitic prevalence pattern of corresponding regions. The results depict a noticeable correlation between the studied parameters and seasonal variation in the occurrence of each type of ectoparasites. This outcome on the interaction of studied parameters and ectoparasitism is intriguing and it opens a huge scope for future studies on the biometeorological aspects of host-parasite ecological interplay and evolutionary biology. The better understanding of climatological aspects of ectoparasite occurrences helps goat farmers in formulating appropriate timely intervention strategies for the economic control of ectoparasites, which in turn tackles ectoparasiticidal drug resistance and reduces threat of vector-borne diseases. © 2020, ISB.

Parathormone is a key polypeptide hormone controlling bone remodeling by influencing calcium, phosphorus, and vitamin D homeostasis in mammalian body. This report describes unusual presentation of osteodystrophy causing facial hyperostosis due to nutritional secondary hyperparathyroidism in a puppy. A female Labrador Retriever dog aged 5 months was presented with progressive bilaterally symmetrical swelling on facial region, hypersalivation, and reduced growth rate. Excessive meat intake in daily ration since weaning was reported. Clinical examination revealed dyspnoea, open mouth breathing, epiphora, excessive nasal secretions, tachycardia, pale mucous membranes, debility, loosely attached teeth, and pigmented oral mucosa of the upper jaw. Microcytic anemia, lymphocytosis, eosinophilia, monocytopenia, hypoproteinemia with hypoglobulinemia, hyperalbuminemia, hypocalcemia, hyperphosphatemia, and decreased Ca:P ratio were evident in the hemato-biochemical study. Lateral radiographic view of the head revealed hyperostosis of the facial bones with irregularly arranged teeth on the upper jaw. Nutritional secondary hyperparathyroidism–induced facial osteodystrophy was diagnosed in the animal based on the history and other supporting clinical evidence. The animal was treated with a protocol extending for 4 weeks using calcium, calcitriol, essential minerals, vitamins, and steroids. The animal showed considerable improvement on day 14 and regained normal facial architecture by day 28 of the therapy. © 2021, The Author(s), under exclusive licence to Springer-Verlag London Ltd. part of Springer Nature.

Background: The present study evaluated the antioxidant as well as the anti-diabetic potential of Terminalia chebula (Haritaki) and Withania somnifera (Ashwagandha) in subclinically diabetic dogs. Methods: A total of thirty subclinically diabetic dogs were divided into five groups of six animals each; Group I (Positive control), Group II (T. chebula extract), Group III (W. somnifera extract), Group IV (T. chebula and W. somnifera extracts at 1:1 ratio) and Group V (N- acetylcysteine). Six apparently healthy dogs were kept as negative control (Group VI) for the study. The animals were evaluated based on diabetic biomarkers (Random blood glucose, fasting blood glucose, glycated hemoglobin, serum fructosamine and serum insulin) and oxidative stress markers (lipid peroxidation, reduced glutathione, superoxide dismutase and catalase activities) on days 0, 15 and 30 of the study. Result: Significant oxidative stress was observed in the subclinically diabetic dogs and the supplementation of N- acetylcysteine, T. chebula and W. somnifera effectively curbed the oxidative impairments and further progression of diabetes. The improvement in oxidative, as well as diabetic biomarkers, was predominant in Group V animals, followed by Group IV, Group II and Group III. It may be concluded that therapeutic modulation of redox mechanisms may aid in the clinical management of subclinical diabetes mellitus, however, the mechanisms involved should be further explored. © 2023 Agricultural Research Communication Centre.
