Primary data were collected from value chain actors, viz., small and micro dairy processing units (main actors), milk supplier, i.e., dairy farmer and milk vendors (upstream actors) and traders (downstream actors) in Karnal district of Haryana state of India. FSI of two identified milk procurement systems, viz., (i) own collection centres, and (ii) private vendors were compared. Processing units with own collection centres in production catchments have been able to establish better linkages with dairy upstream actors and resulted in better overall FSI (0.66) than those processing units procuring milk from private vendors (with FSI as 0.51). Further, the profitability of the processing unit is positively associated with the FSI, as consumers are willing to pay higher prices for safe milk. There was a need to design efficient milk procurement systems; design and development of efficient milk transport systems and processing technology along with training in post-milking handling for small vendors and processors for better food safety compliance in the milk value chain of the informal sector.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43734695","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}

Seventy-two crossbred cows initially milked in tandem milking parlour were relocated to herringbone parlour and observed for 45 milking sessions. Recording of behaviour was done for the individual animal as they entered the holding area till exit after completion of milking. The results showed that there was marked behavioural changes associated with the relocation of animals. Sharp decline in milk yield was observed on the day of relocation which improved in subsequent milking sessions. The mean cortisol level pre and post milking was significantly (P<0.01) high in novel parlour to which the animals were unfamiliar. The behaviour of animals post-adaptation in holding area and milking area was found to be significantly (P<0.01) associated with the milkablity traits in terms of milk yield and milk flow. The temperament score of cows significantly (P<0.01) affected their milk yield and milk flow characteristics. No definite trend was seen due to effect of elimination behaviour on milkability. The study concluded that although lactating dairy cows have tendency to adapt in a new system, shifting them in the midst of lactation may cause production losses. The cow behaviour post-adaptation in milking parlours having batch milking may serve as potent tool to select and split large herds, based on milk yield and milk flow rates.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45287995","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 gene is located on chromosome BBU21 and consists of 17 exons spanning over 32.95 kb of genomic DNA. The present study was undertaken to identify allelic variants in exon 8 and 13 of lactoferrin gene and their association with incidence of clinical mastitis in Murrah buffalo. A total of 200 lactating Murrah buffaloes, grouped as mastitis affected and non-affected, were included in the study. Genomic DNA was isolated from the whole blood sample of each animal. Two primer sets were used to amplify exon 8 and 13 of lactoferrin gene, which yielded respective amplicons of 216 bp and 211 bp. The polymerase chain reaction-restriction fragment length polymorphism analysis of lactoferrin gene revealed monomorphic pattern in exon 8 and polymorphic pattern in exon 13. Hpy 188I -RFLP for exon 13 exhibited polymorphism with three genotypes: AA, AB and BB with respective frequencies of 0.20, 0.58 and 0.22 whereas, frequencies for A and B alleles were estimated as 0.49 and 0.51. Comparison of nucleotide sequence of exonic region of lactoferrin gene in Murrah buffalo with that of Bos taurus cattle revealed a total of 5 mutations out of which 2 were transition and 3 were transversion. The SNPs in exon 8 were found to be non synonymous and revealed two amino acid changes in exon 8 of Murrah buffalo as compared to Bos taurus cattle. Chi-square (χ2) analysis indicated non significant association between genetic variants of exon 13 and incidence of clinical mastitis.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48935510","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}

Methane has higher global warming potential which is 28 times more than CO 2 . The present investigation was conducted to evaluate effect of supplementation of soybean straw and seaweed ( Sargassum johnstoni ) in the ration of dairy cows on methane mitigation and production performance of animals. Six crossbred lactating cows received three treatments in Switch Over Design for 135 days in 3 periods of 45 days each. The treatments consist of T1: TMR with compound concentrate mixture and wheat straw (60:40); T2: TMR with 20 % each of wheat straw and soyabean straw and 60 % compound concentrate mixture and T3: TMR (60:40) with seaweed ( Sargassum johnstonii ). Methane emission was estimated by SF 6 tracer technique. The DM and nutrient intake were at par in T1 and T2, but was significantly low in T3. The milk yield observed was also less in T3 than T1 and T2 which were at par. The methane production was significantly reduced by 20.79 % and 16.53% (P<0.05) in soybean (T2) and seaweed (T3) supplemented group as compared to control group. The loss of dietary energy through methane also significantly decreased in T2 and T3 than T1. The results indicated that supplementation of soybean straw and seaweed in TMR has tremendous potential for methane mitigation in crossbred cows. However, further research is needed to ameliorate the feed and nutrient intake by increasing palatability of seaweeds based TMR.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44928201","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}

As farmers are shifting from low input-low output to high input-high output and traditional and subsistence to commercial dairy farming, this study assesses the impact of resources being used optimally through herd size categories by the dairy farmers for buffaloes and crossbred cows in the Middle Gujarat region. The resource use efficiency analysis helps the dairy farmers in taking appropriate decisions regarding resource allocation without using additional resources for enhancing their income. The findings show that on an average, the costs of human labour, green fodder and concentrates had significant influence on milk yield for buffalo milk production while costs of human labour, green fodder, concentrates and veterinary and medical charges had significant influence on milk yield for crossbred cow milk production implying that one per cent increase in the use of these inputs can led to increase in the gross returns from milk. Milk production for buffaloes was in decreasing returns to scale while on an overall basis, milk production for crossbred cows was increasing returns to scale. Further, the difference between MVP and its acquisition unit price for human labour in small category, green fodder in overall category and dry fodder in marginal category in buffalo milk production and price for human labour in medium and overall category and green fodder in large category in crossbred cow milk production were found positive and significant indicating that the dairy farmers have an opportunity to increase their profit by using more of these inputs on their farms. Thus, the study concluded that only in crossbred cows, milk production was size neutral.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48261996","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}
