Mastitis, most often udder infection of dairy animals attracted concerns due to heavy economic loss to dairy industry and public health. This study was conducted to determine the cultivable bacterial species associated with bovine clinical mastitis and their resistance patterns to different antimicrobials. The milk samples from 272 quarters of cows suffering from clinical mastitis were investigated. A total of 110 bacterial isolates belonging to 14 different genera were isolated and identi ed. Aminoglycosides and Quinolones were found to be most effective antibiotics. We demonstrated Extended Spectrum β Lactamases (ESBL), Cephalosporins, Tetracyclines, Vancomycin and Chloramphenicol resistant Grampositive and Gram-negative bacteria along with Vancomycin Resistant Enterococci (VRE), Multiple Drug Resistant Gram-Negative Rods (MDR-GNR), MDR-Pseudomonas (MDR-P) and MDR Acinetobacter (MDR-A). The ESBLs and cephalosporins resistant S. aureus isolates showed resistance to Vancomycin. Wide spread of resistance among Streptococcus uberis against ESBLs and Cephalosporins, widely used antibiotics in bovine mastitis, was documented. Variable MDR patterns were recorded for every species. MDR transfer from non-pathogens to emerging foodborne and established mastitis pathogens could be potential problem to dairy industry as well as public health.

The study was conducted to identify the typology of the Osmanabadi goat-keeping households and farms in a home tract of the breed during 2020-21. Hierarchical and K mean clustering techniques were used to classify 107 households into three homogenous clusters. In extensively large flock keeping households with large landholdings (C1, n=25, 23%), the respondents were using scientific practices to a great extent than the households with extensively keeping small flock with small landholdings (C3, n=59, 55%). Goat rearing was being the sole farm activity of relatively more households in C3, where primarily women had control over farm decisions and returns than the households who semi-intensively kept medium flock with medium landholding (C2, n=23, 22%). Households in C3 were mostly using open sheds, had lower goat income than the rest of the clusters. Households in C2 were higher in employment generation than households in C3. The typologies of Osmanabadi goat-keeping households showed significant heterogeneity in clusters and critical points which need to be considered to find sustainable solutions. Government policies and extension approaches are likely to be more effective if they consider the heterogeneity in the planning and delivery of extension interventions.

The current study was conducted in Maharashtra to ascertain the impact of dairy farming trainings organized by selected three Krishi Vigyan Kendras on selected economically important parameters. Propensity score matching method was used to avoid selection bias and build a statistical comparison group of non-trainees comparable to trainees. The study revealed that there was no significant difference among trainees and non-trainees related to possession of dairy herd. However, study has shown that milk productivity, annual net income and annual employment generation among trainee and non-trainee dairy farmers were significantly different and comparatively higher among trainees than non-trainees, which indicates positive impact of training imparted by selected Krishi Vigyan Kendras in Maharashtra. Study further revealed that proportion of trainees who were deriving higher economic benefits from dairy farming in terms of productivity and income was quiet less. Hence, it is suggested that training organizing institutes should intensively plan more trainings of long duration ensuring larger and wider participation of population with follow up and post-training information support.
