In recent years, these attributes have generated interest towards screening of lactic acid bacteria (LAB) for functional food production. In this present study, lactobacilli (n=34) (13 L. casei, 6 L. paracasei, 11 L. brevis, 3 L. pentosus and 1 L. plantarum) from varied sources viz. Nigerian fermented foods and human specimens were screened qualitatively and quantitatively for BSH activity using the direct plate assay and cell free extracts (CFE) of overnight cultures. To establish a correlation between BSH and cholesterol reduction, 12 isolates displaying high precipitation over bile salt agar plates, and high BSH enzyme activity in CFE were selected for in vitro cholesterol reduction assay. Results showed that 58% of the isolates from humans, and 36% from fermented food origin showed larger zones of precipitation. The highest BSH activity was exhibited by Lactobacillus casei GR4 (76mM) after 10 min of incubation, an isolate from fermented food. Isolates from human specimens expressed higher enzyme activity compared to those from fermented foods with significant increase (P<0.05) after 30 min incubation. Cholesterol level was variable as L. pentosus 8ST5 and 8ST7 had 2 and 4% cholesterol levels in the medium; while L. casei and paracasei group (Lactobacillus casei group, LCG) 3MB4, 8BM6, BK4 and L. brevis GR29 had 7%/ml each proving their application in food formulation, reduction of hypercholesterolemia, and as prophylaxis for controlling serum cholesterol levels.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42378571","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study was conducted to assess the nature of tick infestation, awareness and methods of tick control among eight purposively selected village panchayats of district Kangra, Himachal Pradesh. Further out of these 8 panchayats, 200 dairy farmers were randomly selected during 2018-2019.The study indicated that tick infestation is acute in hilly regions of Himachal, India and farmers rely mainly on animal husbandry institutions for seeking scientific inputs/information. Synthetic acaricides were widely in practice (100.0%), though 40 percent of farmers relied on both synthetic and indigenous herbal medications. The high use of acaricides was due to the presence of veterinary institutions in every village panchayat in the region. The majority of dairy farmers (79.5%) reported that these synthetic acaricides were effective up to 30 days only and recurrent infestation on animals was noticed. Suitable extension interventions for improved housing management and proper tick disposal must be applied to overcome the problem in the region.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42922803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Fourteen type of udder traits were measured for each of randomly selected 100 lactating cattle maintained at Livestock Research farm, NDRI, Karnal, India. The data were analysed by least squares methods using the general linear model procedures including parity, stage of lactation and season of calving at classification as fixed effects. Traits viz. Udder balance, Rear Udder Height, Teat Diameter, Teat Length, Central Ligament, Udder Circumference, Udder Width and Teat Circumference were significantly (p<0.05) affected by parity. Stage of lactation was significant (P<0.05) source of variation for Shortest distance from teat ends to floor, Rear Udder Height, Central ligament and Udder Circumference while season of calving significantly (p<0.05) affected Rear Udder Height, Teat Length and Rear Udder Width.

It’s also known as functional food, which is food that clearly claims to have health advantages as well as the ability to enhance the immune system. Yoghurt is a fermented dairy product that is in great demand for its nutrient content, bacterial activity and wide product range in terms of flavours and textures. In this study, physicochemical, microbiological and sensory differences of probiotic set yoghurt incorporated with different concentration of Jaggery were evaluated, as well as the changes taking place during storage at 4°C for 21 days. During the storage, the addition of jaggery improved survival of Lactobacillus delbrueckii subspecies bulgaricus (ABT-7) and Streptococcus thermophiles (YoFlex Express 1.0) from CHR HANSEN, Denmark were used as starter culture for yogurt preparation. All yogurts exhibited a decrease in pH accompanied by an increase in titratable acidity during storage. Therefore, this study revealed that jaggery could be used to produce probiotic set yoghurt with improved physicochemical, microbiological and sensorial attributes.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48989529","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A cross-sectional survey using a multistage random sampling procedure was conducted and data was collected from the dairy food supply chain associated stakeholders in Karnataka, India. The results revealed that milk providers to the co-operatives increased by 4.67 % and the quantity of milk collection increased by 25.15 % during the lockdown. On the service front, 41.3% of the dairy cooperative societies faced animal feed shortages. The average per day milk consumption increased by 42.7 % during lockdown mainly driven by the return of family members from cities to villages. However, the gross income realized through milk sales by the dairy farmers decreased during the lockdown period mainly due to reduced milk prices offered by the co-operatives. The gross income realized through the sale of milk products by the vendors declined by 5.11% due to a fall in demand for various milk products. Despite many problems faced by the cooperative sector during the lockdown, it acted as a buffer and protected the dairy food supply chain from the free market and capitalist breakdown in Karnataka.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45950718","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
