Aim: The current study aimed to assess the knowledge, attitude, and practices pertaining to antibiotic usage among the field veterinarians who serve as nodal officers playing a crucial role in disseminating knowledge to the farmers regarding livestock management practices in India. Materials and Methods: A pilot study was conducted in which 106 of the 173 field veterinarians of Haryana, India, agreed to contribute through their valuable participation in the study. The collected data were critically analyzed by simple descriptive statistics, and the responses were ranked using Garrett's ranking method. Results: Our study found that most of the clinicians were aware of the fundamental clinical aspects of antibiotic resistance (AR), i.e., the general causes and transmission of resistance, response during treatment failure, and safe disposal of hospital waste. Further, implementation of "antibiotic stewardship" (rational/responsible use of antibiotics) and interruption of AR transmission by means of cross-kingdom pathogens are two ways to restrict the spread of resistant pathogens which were not in the clinical purview of majority of the clinicians. This highlights a lack of awareness and scope of improving clinician's knowledge pertaining to AR. Moreover, we got to know the methodology adopted by farmers for disposal of infected milk from diseased udders as well as their attitude toward diseased and unproductive animals. Conclusion: This study provides snippets of the current animal husbandry practices prevalent at the field level which would assist to plug in the gaps of knowledge regarding AR among the veterinarians as well as the general public and serve to reduce its deleterious impacts in Indian animal farming as well as in the world through the concept of "One World, One Health."

Background: The Malpura sheep is hardy breed of semi-arid region of Rajasthan. Farmers do not get the due share for their heavy weight lambs as animals are never sold on weight basis. Researchers have worked out the ways of predicting the live weight of sheep/goats using body measurements. However, very few studies have tried to address this issue, especially in India. Aim of this study was to construct a prediction scale for live weight of sheep using simple measure of heart girth and body length, such scale will further benefit the shepherds to guess the live weight of the lambs sold and expect the desired price from the customer. Methods: The present study was conducted on 1164 records of 823 Malpura sheep at CSWRI, Avikanagar. The data on live weight (N=1164) and corresponding morphometric measures on heart girth and body length were digitalized and subjected to analysis. we used 14 linear predictors and regressed them on the live weight to obtain the estimates of regression, coefficient of determination and derived the prediction equations using the regression coefficients for prediction of live weights. Result: Our study revealed that it is possible to create a measurement scale for prediction of live weight of the sheep using simple arithmetic. Several linear regression scales using body length and heart girth were developed. The best scale (L+G) had a prediction equation as: Y = -49.743+0.576L+0.562G, where Y is live weight. The R2 was 0.883, which was not significantly more than linear regression scale (L+G). This will help the farmers to quite confidently score animals for their live weights across all the age groups. With the help of measurement tape, he can easily measure the heart girth and the body length of the sheep.
