The change in quality attributes in terms of sensory, chemico-physical (pH, acidity, thiobarbituric acid (TBA), acid degree value (ADV) and color (L*, a*, b*) textural and microbiological (total plate count, coliform and yeast and mold) were studied at an interval of 10 days. Also, linear regression models were developed to correlate the changes in attributes with storage time. Keeping quality of both CD and SCD decreased over the period of time. An increase in firmness, SPC, YM, TBA, and ADV was observed for both the samples, whereas pH, adhesiveness, and sensory scores decreased. On day 30, SCD exhibited significantly lower acidity, ADV, TBA, tyrosine, and microbial count than the CD. Also, the sensory scores of SCD were significantly higher compared to CD. Linear regression equations between days and quality attributes showed a determination coefficient (R 2 ) >0.85. This study clearly shows that keeping the quality of cheese dip depends on the composition and ingredients used for its manufacturing. In conclusion, the spoilage of CD is mainly accompanied by an increase in acidity due to the growth of microorganisms responsible for decreased sensory scores and changes in textural properties of the product. Accordingly, the heating time-temperature combination can be altered to further improve the keeping quality of the product at refrigeration temperature.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46414170","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 six (n=6) healthy pregnant Murrah buffaloes and 23 symptomatic buffaloes with symptoms indicative of metritis (n=5), endometritis (n=6) mastitis (n=8), and retained placenta (RP) (n=4) were selected from the ICAR-NDRI Cattle herd. Blood samples were collected from each healthy buffalo on days -21, -14, -7, 0, +7, +14, +21 relative to calving. Blood samples were collected from unhealthy buffaloes twice on alternate days as and when the symptoms of reproductive abnormalities were noticed. The results revealed that the plasma growth hormone was significantly (P<0.05) elevated in buffaloes exhibiting symptoms of metritis (7.40±0.96 ng /mL), mastitis (9.23±1.60 ng /mL), and RP (6.63±0.80 ng/mL). Similarly, plasma insulin level was significantly higher (P<0.05) in buffaloes infected with endometritis (1.53 ±0.21 ng/ml), mastitis (1.32 ±0.26 ng/mL), and RP (1.24 ±0.15 ng/mL). But, the plasma IGF-1 was significantly lower in buffaloes exhibiting symptoms of metritis (128.43±5.38 ng/mL), endometritis (112.65 ±4.38 ng/ mL), and mastitis (123.61 ±3.99 ng/mL) except in RP (122.21±5.10 ng/mL) than normally calved buffaloes (123.80±4.96 ng/ mL).

To optimize the level of coagulant and temperature, Three Level Factorial Design was used. This included three levels of salt (0.2, 0.4 and 0.6%, w/v on soy milk basis) and acid (0.15, 0.25 and 0.35%, w/v on soy milk basis) coagulants with three levels of coagulating temperature (75, 82.5 and 90C). Thus 13 RSM experiments including five central and eight axial points were conducted to produce soytofu samples with each of the coagulant. Soytofu samples were evaluated organoleptically on nine point hedonic rating scale. Results revealed that the optimum concentration of coagulants (% w/v, on soymilk basis) and coagulating temperature (C) of soymilk for making quality soytofu was 0.6, 86.55, 0.57, 84.9, 0.6, 87.23, 0.46, 86.18, 0.35, 89.33, 0.3, 80.25 and 0.15%, 87.45C, respectively, for CaCl 2 , CaSO 4 , MgCl 2 , MgSO 4 , lactic acid, acetic acid and citric acid coagulants.

It is a better dairy animal in comparison to cattle in terms of better feed (roughage) conversion efficiency, greater resistance to diseases and higher milk fat percentage. But anoestrus is the most important cause of poor reproductive performance in buffaloes both in field condition as well as in organized farm. The percentage of anoestrus is more in rural areas mainly due to malnutrition, lack of scientific knowledge and improper management practices causing huge economic losses to the farmers. Thus this study was conducted to test the effectiveness of GPG protocols in farmers field for treating anoestrus in buffaloes with PGF2α or GnRH protocol under the field conditions. A total of 36 animals were selected from different affected villages of Mathura district with good body condition score (BCS >2.5), parity of two or above, healthy reproductive organs and history of minimum 6 months anoestrus problems after reaching the age of breeding or after calving or the last breeding were selected.

This may affect the oxidative stability of butter. Therefore, the present study was conducted to evaluate the impact of storage on the physico-chemical, textural and sensory attributes of the fortified butter samples packed in polypropylene cups and stored at 5 and -18 °C. The samples were analysed for 90 days with an interval of 15 days. During the storage, the samples were analysed for physico-chemical properties, oxidative stability, textural characteristics, sensory characteristics and microbial quality. Control sample showed higher (4.35 h) induction period than samples prepared by adding flaxseed oil (2.36 h) and flaxseed oil emulsion (2.56 h) as studied by rancimat. Peroxide value, free fatty acids and TBA value increased significantly (P<0.05) during storage however, the values were within the acceptable range. The optimized butter samples were examined for storage stability under refrigeration and frozen conditions for 90 days. Firmness, work of shear and yield stress increased slightly during the storage and samples stored at -18oC showed higher values than refrigerated storage. Even though, overall sensory acceptability decreased significantly (P<0.05) during the storage and the samples stored at -18oC showed higher score than refrigerated storage; it was still above 7.5 on 9 point hedonic scale. No microbial growth was observed throughout the storage period. Thus, it is concluded that omega-3 fatty acid fortification doesn’t adversely affect the storage stability of fortified butter and the butter has good sensorial acceptability and oxidative stability for 90 days of storage period.","PeriodicalId":45524,"journal":{"name":"INDIAN JOURNAL OF DAIRY SCIENCE","volume":" ","pages":""},"PeriodicalIF":0.3,"publicationDate":"2021-09-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46473870","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}

Meteorological data of the region (where field progeny testing was undergoing), were collected from the center of Indian Meteorological Department (IMD), Pune to know the association of AFC with heat stress indicators. The least squares mean and heritability of AFC were estimated. Various heat stress models were screened for optimization (Based on value of R, adjusted R, AIC and BIC) and effect of heat stress was quantified. Depending on the estimate of AFC and THI, months of the year were classified in to various heat stress zones. Sires were evaluated (both by BLUP-SM and BLUP-AM) for AFC in different HSZ, in order to identify optimum sire for each of the zone. The least squares mean estimate for AFC was 1419.61±2.18 days. The heritability estimates were obtained as 0.14±0.02 (LSML), 0.775±0.003 (BLUP-SM) and 0.13±0.023 (BLUP-AM). THI 6 model (Yousef, 1985) was found to be the best suited model and it was observed that AFC was declined by 1.26 day with per unit rise in THI. Year was classified in to NHSZ (non heat stress zone – November to March), HSZ (heat stress zoneApril to October) and CHSZ (critical heat stress zoneJune to August). The average breeding values of Mehsana buffalo bulls evaluated for AFC by BLUP-SM and BLUP-AM in NHSZ, HSZ and in CHSZ were estimated to be 1389.36, 1380.37 and 1375.04 days and 1389.33, 1382.85 and 1375.53 days, respectively. It was indicated that the bulls having superior performance in NHSZ were not as better performer in HSZ and CHSZ.

There was significant difference in textural, functional and sensory properties between natural Mozzarella cheese and its analogue. Natural cheese had higher hardness, cohesiveness, springiness, gumminess and chewiness while had lower adhesiveness. Analogue possessed better shredability but required more time for melting in oven at 230°C compared to natural cheese. The natural cheese had higher meltability, stretchability and fat leakage. Natural cheese outplayed analogue in terms of sensory characteristics particularly for appearance, flavor, melting and stringiness while analogue was less chewy than natural cheese.
