Prevalence of Sub-Clinical Mastitis in Cattle and Effect on Milk Quality

Abstract

| Present study was carried with an objective of finding prevalence of subclinical mastitis (SCM) and effect on milk quality in cross-bred (CB) and desi-dairy cattle (Zebu, Nondescript-ND) of Hassan district, Karnataka, India. Diagnosis was based on cow side tests -California mastitis test, and mastrip which substantiated by Direct Microscopic Somatic Cell Count (DMSCC). Upon evaluation of 150 CB and 40 ND cattle,65 (43%) of CB cattle and 5 (12%) of ND cattle were found positive for SCM on California mastitis test and mastrip test. Overall, 70 of 190 animals (37%) were positive for SCM. The DMSCC enumeration found 0.3-0.5 million SCC per mL for normal and 0.6-1.5 million SCC per mL for SCM positive milk. The milk pH, fat and Solids Not Fat (SNF) exhibited slight variance between normal and SCM positive animals. The prevalence was more common in hygiene and welfare compromised animals.

Proteomic Analysis of Pleurotus ostreatus Grown on Glucose and Xylose Mixtures in Submerged Fermentation Provides Insights into Differentiated Mycelial Composition

“…Proteomic analysis is a powerful tool that can provide a systematic understanding of molecular level events of filamentous fungi [1]. Proteomics includes identification, quantification, localization, modification, interactions, and activities of proteins [2]. Proteomic analysis of several filamentous fungi genera such as Aspergilli, Botrytis, Neurospora, Penicillium, Phanerochaete, Pleurotus, Trichoderma, Lentinus and Mortierella has already been done [1].…”

“…Proteomic analysis of several filamentous fungi genera such as Aspergilli, Botrytis, Neurospora, Penicillium, Phanerochaete, Pleurotus, Trichoderma, Lentinus and Mortierella has already been done [1]. Concerning functional foods and nutraceuticals studies proteomic analysis has already been conducted about food quality and safety, authentication, microbial toxins and toxins in fermented foods, and food allergens [2][3][4][5][6][7]. The effect of carbon sources on different fungi and the proteomic analysis to estimate at a molecular level what triggers the different production of bioactive compounds, proteins such as enzymes as well as secondary metabolites is very crucial.…”
