Phylogeny study of methicillin resistance Staphylococcus aureus (MRSA) isolates collected from milk and nasal swab associated with ruminants based on genome sequence
Methicillin resistant Staphylococcus aureus is an economically important disease causing bacteria for ruminants (Cattle buffalo, sheep and goat). The study examined the milk (350) and nasal swab samples (375) for detection of MRSA. The main goal of this study is genotyping of MRSA isolates are to assign phylogenetic links, clonal relationships, and clonal relatedness to strains between different species of ruminants. Methicillin resistant Staphylococcus aureus was identified based on growth in mannitol salt agar mixed oxacillin-resistant selective supplement, Gram’s staining, catalase tests and polymerase chain reaction (PCR) detection of mecA gene. The disc diffusion test was used to determine the antibiotic resistant against methicillin disk and mecA, spa and whole gene sequence typing for genotyping of isolates for preparation of phylogeny tree. Out of 625 samples 171 samples were positive growth in mannitol salt agar mixed oxacillin-resistant selective supplement. These isolates were further characterized by grams staining and catalase test. Out of 171 methicillin resistance S. aureus isolates recovered from cattle, buffalo, sheep and goat during this study, mecA gene was amplified in 137 (80.11 %) isolates with an amplicon size of 533 kb. On the basis of spa gene data, On the basis of spa gene data, the sequences were analyzed and a phylogenetic tree was drawn in Tree-Base in which SPA7 (MRSA isolate from nasal swab sample of goat) was found to be more distantly related to other isolates. Nasal swab and milk from ruminants were positive for MRSA. All mecA positive MRSA isolates were also resistant for methicillin antibiotic disc. Moreover the genotypes of some MRSA isolates were found different in ruminants.
Performance of Intercultivator on Cultivation of Perennial Fodder Cumbu Napier Hybrid Grass Production System
To study on the efficiency of intercultivator on weed management in Cumbu Napier Hybrid grass cultivation and crop growth performance variety CO-4, the field experiment was conducted at Post Graduate Research Institute in Animal Sciences, Kattupakkam, Kancheepuram District, Tamil Nadu, India during the year 2018-2019. The experiment was laid out with unpaired t test design. The two treatments of control (manual weeding) and treatment (using intercultivator) were compared. Among the two treatments, using of intercultivator had positively influenced the growth and yield characters and number of cuttings and yield of Cumbu Napier Hybrid Grass in all the seasons. The maximum plant height, number of tillers hill- 1, fodder yield were recorded under the treatment of using intercultivaor. The fodder yield was lower in manual weeding (control) in all the seasons.
Preservation of green fodder as fodder block for feeding in dairy cattle
Densification of roughage-based crop residues and other green fodders in compact, ready to eat feed block is an effective solution for animal feed management. Such fodder blocks can be stored over a long period of time and transported economically over long distances. Crop residues, leguminous green fodder, non- leguminous green fodder, weeds from field and tree fodders were collected and preserved as fodder blocks. The dimensions of the blocks were 30 x 30 x 10 cm. The weight of each block was approximately 0.8 kg. These blocks were incorporated with minerals and salt. The moisture content of fodder blocks after 2 days of drying under sun were 14.62. At 75% relative humidity, the fodder blocks could be safely stored without any protective packaging. The fodder blocks contained 6.71% to 28.52% crude protein on dry matter basis. The in vitro dry matter degradability of fodder blocks were found to be minimum 40.38% in paddy straw based block and 60.2% in mixed tree fodder block. The mean daily dry matter intake of fodder blocks varied from 1.14% to 3.61%. The cost of the fodder blocks varied from Rs. 3.50 to Rs. 5.25 weighing 1 kg according to the type of fodder included. The block making is a technology to preserve the crop residues, green fodder, tree fodder and any other green from the field with easy transportation, storage and during the scarcity period for feeding dairy cattle.
Training need assessment of Umblachery breed cattle farmers in Cauvery delta region, Tamil Nadu, India
Breed conservation needs technology dissemination which necessitates training. Training imparted to farmers based on training need assessment (TNA) desirably impact farming activities. Hence, the study aimed to assess the training needs of farmers on Umblachery breed cattle farming. Totally 120 farmers were selected using simple random sampling technique for the study from Nagappattinam and Thiruvarur districts, the breeding tract of Umblachery. Identified training needs were classified under eight different areas and incorporated in the structured interview schedule to determine the training need index (TNI). The data were collected through personal interview and analysed. The results reveal that the farmers perceived training on communication and marketing of Umblachery cattle as most important followed by feeding management (II), calf management (III), clean milk production (IV), herd health management (V), breeding management (VI), housing management (VII) and animal selection (VIII) with mean score of 2,56, 2.50, 2.27, 2.26, 2.12, 2.09, 1.98 and 1.88 respectively. The findings would help the stakeholder institutes, which impart training to Umblachery breed cattle farmers, in designing training curriculum for making the training impactful.
Leaf nutrient analysis of gerbera varieties grown on different growing media under soilless culture
Nutrient concentrations in plant tissues are often regarded as the most reliable measure of the nutritional quality of different crops. Leaf nutrition analysis is an excellent way to establish balanced fertilisation techniques. The current study seeks to assess macronutrient content in ten varieties of pot gerbera cultivated on three different growing conditions after 90 days of planting. The experiment was conducted in the polyhouse at the Centre for Protected Cultivation Technology (CPCT), ICAR-Indian Agricultural Research Institute (IARI), New Delhi, from February to May 2022 and 2023, using a completely randomised design with a factorial concept. The results showed that the leaves of var. Glorious Orange grown in Cocopeat + Perlite + Vermiculite (3:1:1) (M2V2) had the highest total leaf nitrogen content (2.45 %), whereas the leaves of var. Bighorn grown in Cocopeat + Perlite + Vermiculite (3:1:1) (M2V9) had the highest leaf phosphorous content (0.42 %). However, the leaves of var. Glorious Yellow exhibited the highest leaf potassium content (3.53 %) when grown in Cocopeat + Perlite + Vermiculite (3:1:1) (M2V4) than in any other treatment combination. There was no significant relationship between varieties and growing media.
