The sorption isotherms obtained were sigmoid in nature. Nine different mathematical models were found to effectively describe the moisture sorption data on the basis of regression analyses and goodness of fit. Each model was statistically evaluated by means of percent root mean square and coefficient of determination. The GAB model gave the best fit in the entire range of aw. Temperature dependence of the GAB constants and good fit were determined. Using Caurie’s model, the properties of sorbed water such as monolayer moisture content, number of adsorbed monolayers, density of sorbed water, bound water content and surface area of adsorption which decreased with an increase in temperature, were calculated. The monolayer moisture content ranged from 1.82 to 6.25 g/100 g solids in Mohanthal.","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":"42627093","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}

However density of milk samples did not differed significantly among both different levels as well as taluka. Most of the compositional parameters were found below the FSSAI standards for buffalo milk. More or less amount of extraneous water was added in all the milk samples of Parbhani subdivision. Adulterants viz, detergents, skim milk powder (SMP), sucrose, nitrate and urea was detected in vendor™s milk samples. None of the adulterant was detected in dairy of Parbhani subdivision; however CC milk samples of Jintur and Purna taluka were only positive for presence of detergent. From the study, it is concluded that adulteration of milk is a generally practiced by vendors which results in the deterioration of nutritive and microbiological quality of milk.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48044853","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}

These products being rich in antioxidants along with good source of minerals, vitamins and other essential nutrients could have enormous potentials to guard against many human diseases. To the tribal people of Ladakh, these could overcome the deficiency of micronutrients caused due the shortage of fruits and vegetables during the winter season. The nomads of Changthang region of Ladakh could carry these products easily as nutritional supplements during their year round migration. Dried dairy products viz. churpe-balls and churpe-strips were developed with the incorporation of apricot powder into cottage cheese at different levels (05, 10, 15 and 20%) and spinach powder at levels (03, 06, 09 and 12%), respectively. Physico-chemical, antioxidant, colour, sensory and microbial attributes of the products were studied. The addition of apricot powder in balls resulted in significant (P < 0.05) increase in ash, hydrosoluble vitamins (thiamine, riboflavin and ascorbic acid), titratable acidity and antioxidant activity and decrease in protein, fat, minerals (calcium, magnesium and sodium) and pH. Incorporation of spinach powder in strips resulted in increase (P < 0.05) in ash, calcium, magnesium, hydrosoluble vitamins (thiamine, riboflavin and ascorbic acid), titratable acidity and antioxidant activity and decrease in protein, fat, sodium and pH. A non significant increase in moisture and lactose contents of both the value added products was also observed. L* and a* increased in both the products with the increase in level of supplementation (05 to 20% in case of balls and 03 to 12% in case of strips), however, b* decreased in balls and increased in strips. Rise in the supplementation levels resulted in decline in microbial load in the products whereas, with the advancement of storage period up to 120 days, there was rise in microbial population but was found within safe limits. The overall acceptability of the churpe-balls was highest at 15% level and that of churpe-strips was highest at 09% level of blending.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47395571","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}

It was observed in the present study that pasteurized toned milk (3% fat, 8.5% SNF) had better sensory properties and higher viscosities than pasteurized skim milk, showing the importance of fat in consumer acceptance of milk samples. In commercial practice, skim milk is therefore traded only upon UHT treatment as it was much better in sensory properties than pasteurized skim milk. Since carbohydrate derivatives are usually used as fat mimetics, Inulin fruitafit text and fruitafit HD and polydextrose were added at different levels (0-2.5%) to skim milk to improve its quality attributes. It is observed that incorporation of a 1% level of polydextrose in combination with either of inulins (@ 1%) had improved viscosity and sensory properties. The rheological properties of such milk were comparable to that of toned milk and better than that of UHT skim milk. The quality of the skim milk added with carbohydrate derivatives was not affected by the normal processing treatments, such as homogenisation, pasteurization, boiling and sterilization. The gross constituents such as fat, protein, lactose and ash contents did not differ much with the control skim milk sample. The pH, acidity, and color (measured as % reflectance) of the skim milk samples added with the derivative were within the normal range. The samples were heat-stable, had high MBR time and when packed in LDPE pouches and stored at 50C kept well for two days. After appropriate approvals from the Food Safety and Standards Authority of India (FSSAI) pasteurised skim milk added with GRAS carbohydrate derivatives can be commercialised with improved consumer acceptance and affordability.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44712662","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}

Results showed that Bu_LALBA ORF consisted of 429 bp long (142 aa residues) with three nucleotide variations at 111bp, 147 bp, and 291 bp but no change in amino acid sequence. The MSA showed that the Bu_LALBA was more different from the pig and human LALBA sequences. The phylogenetic tree showed that the cow, yak, and buffalo formed one cluster, while the buffalo was more closer (94%) to domestic yak (Bos grunniens). Results of ExPASy analysis showed that the Bu_LALBA protein was acidic (pI, 4.81), thermo-tolerant, and hydrophilic. However, the presence of random coil (33.80%) and α-helix (41.5%) in Bu_LALBA protein suggest that the protein was flexible and thermostable. Thirty liner motifs were identified, indicating that the Bu_LALBA act as regulatory protein. The tertiary structure of Bu_LALBA predicted by I-TASSER showed a more stabilized nature of LALBA protein. Further, the Ramachandran plot validated the 3-D structure of Bu_LALBA, which was of decent quality. The presence of four ligand-binding sites in Bu_LALBA (calcium ion, glycine, N-acetyl-L-glutamate, and N-acetylglucosamine) proposed that the LALBA binds to several fatty acids and ions. The presence of four serine, four threonine, two tyrosine residues, and six methylated lysine and five acetyl-lysine sites in Bu_LALBA indicated that the protein was involved in post-translational modification processes. IEDB analysis showed the presence of five and one epitope sites in Bu_LALBA protein for B-cell and T-cell, respectively, which suggest that this protein has certain immunological roles.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44574821","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 total of 43 crossbred jersey cattle were examined for 120 days postpartum and divided into four groups, based on their parity number. Correlation and relationship study has revealed significant effect of parity on various parameters. The overall correlation coefficient between BCS and BFT were found to be 54%, 92%, 94% and 90% for P1, P2, P3 and P4 respectively. However, positive to negative significant correlation between BFT and milk yield by parity 1,2,3,4 were 46%, 26%, -10% and -12% respectively. Increased BCS at calving was associated with greater MY in first and second parity cows, and reduced MY in cows of third parity or greater. Furthermore, the correlation coefficient between BFT and BW were found to be low in P1 (r=0.58) and high in P4 (r=0.78). The changes in body fat thickness (BFT) and body weight (BW) by parity difference were most distinct in younger cows i.e. -47.92 percent and -12.05 percent respectively. Relationship (R²) between BFT and BCS in different parity group were 0.29, 0.87, 0.85 and 0.83 respectively (p<0.001). Finally, in case of primiparous cow BFT is valid for estimation of subcutaneous fat and second parity onwards BCS can be adopted to predict the body fat reserve of crossbred animals.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2022-06-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43159912","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}

Two blocks were selected randomly from the district and from each block two experimental and two control villages selected after verifying that villages were not receiving any kind of agromet advisory services from Agromet Field Unit (AMFU) in Thiruvananthapuram. From each experimental village 15 beneficiary farmers were selected and provided with treatment i.e. Agromet Advisory Bulletins were disseminated twice a week (Tuesday and Friday) regularly for 6 months through Whatsapp group and from each control village 15 non-beneficiary farmers were selected. To assess the impact Difference in difference design and regression models were used. The findings revealed that most of the agromet advices were only relevant for crop farmers and the advices relevant for dairy farmers were included less frequently.
