Background: In early post-partum buffaloes, feed intake is generally insufficient to meet the energy demand for milk production; as a consequence, body reserves are mobilized which can result in metabolic disorders and poor production performance. In order to enhance energy intake and reduce the detrimental effects of a negative energy balance, buffalo diets may be supplemented with lipids/vegetable oil. Some reported benefits of vegetable oil supplementation include increased energy concentration in the diet, reduced supply of rapidly fermentable carbohydrates, and better productive performance. Sunflower (Helianthus annuus L.) is an important oilseed crop in India. Sunflower seed contains about 48-53 percent of edible oil. Recent studies demonstrated that sunflower oil supplementation improved the milk production and nutritional quality of milk fat which is beneficial to human health. Therefore, the present study was undertaken to investigate the effect of sunflower (Helianthus annuus L.) oil supplementation on production performance of lactating Mehsana buffalo. Methods: Three experimental groups were as, CON: fed on basal diet (Control), SO125: fed basal diet supplemented with 125 ml of sunflower oil/animal/day and SO250: fed basal diet supplemented with 250 ml of sunflower oil/animal/day for a period of 90 days. Result: There was no difference (P greater than 0.05) in DM intake of lactating buffaloes among the dietary treatments. Dietary inclusion of sunflower oils improved milk yield by 17.9 to 20.7%, 6% FCM yield by 16.4 to 22.9% and ECM yield by 16.0 to 23.0% in SO125 and SO250 groups, respectively as compared to the CON. There were no differences (P greater than 0.05) in milk composition and yields of milk components. The milk fatty acid percentages of C20:0 and C24:0 were significantly decreased due feeding of sunflower oil as compared to the CON. Feeding of sunflower oil did not influence milk fat short chain, medium chain, saturated, unsaturated and polyunsaturated fatty acids in lactating Mehsana buffaloes. The serum concentrations of glucose, total proteins, albumin, urea, creatinine, triglycerides, ALT and AST were not affected (P greater than 0.05) by supplementation of sunflower oil, however, serum cholesterol concentration was significantly (P less than 0.01) increased in SO125 and SO250 groups as compared to the CON group.

Background: During summer the environmental conditions exceeds beyond threshold limit, that enhances heat gain beyond that lost from the body and induces heat stress in cows. The higher temperature and heat stress increases respiration rate, rectal temperature and temperature humidity index, which affects health of the cows. The objective of the study was to create favourable environmental conditions to reduce heat stress and to improve the performance of the cows. Methods: The solar powered cooling system was developed and installed at Main Agriculture Research Station, University of Agricultural Sciences, Raichur District of Karnataka. The functional components of the developed cooling system are foggers, timer-switch, solar panels, battery, water tank, charge controller and hosepipe. The solar panels act as an energy source for the operation pump and the 4-way fogger assembly provides the fogging of water and creates a healthy environment by reducing the air temperature. The system assessment was carried out with 3 levels of variables of foggers (6, 12 and 18 foggers), height of fogger (2.25, 2.50 and 2.75 m) and operational time interval (2, 4 and 6 min). These were statistically analysed along with air temperature (AT), relative humidity (RH), and respiration rate (RR) were also measured. Result: The AT, RH and RR was significantly influenced by the treatment combinations of selected variables and it was found that reduction of 9.2 oC in AT and 49 % (29 breaths min-1) in RR and 47 % increase in RH (66 %) were recorded at 18 foggers at 2.75 m height with 4 min operational time interval. Thus, the developed cooling system was significant (P less than 0.001) in creating optimum environmental conditions for the wellbeing of milch animals.

Background: Pearl millet is rich in dietary fiber and micro-nutrients such as vitamins and minerals apart from the carbohydrates, protein and fat. This study was conducted to fortify low fat chicken meat balls with pearl millet (Pennisetum glaucum) as a dietary fibre source and to assess the physico-chemical, sensory and textural properties. Methods: Emulsion based low fat chicken meat balls were prepared with the addition of Pearl millet flour (PMF) at levels of 4%, 7% and 10%, over and above the amount of meat along with a control and analysed for physico-chemical, textural and sensory properties. Result: In the physico-chemical properties, Emulsion pH, product pH and emulsion stability were not affected by the addition of PMF. Product yield was significantly (P≤0.01) lowered at 4 per cent level of PMF, but increased at higher levels of PMF inclusion. In texture analyses, hardness and cohesiveness were not affected by inclusion of PMF up to 7%. In sensory evaluation, though the scores for texture, tenderness and overall acceptability of 4% treatment were comparable with that of control and significantly (P≤0.01) decreased with increase in the level of PMF, the scores for 7% treatment were above ‘Very acceptable’ level. It is concluded emulsion based functional low fat chicken meat balls could be fortified with pearl millet flour up to a level of 7% without affecting the quality characteristics.

Background: Food safety has emerged as an important global issue with expanded international trade and various public health implications. Milk and dairy products are rich in many nutrients hence offer favourable environments for the growth of various food borne pathogens. Of which in past decades Salmonellosis is a frequently reported zoonotic foodborne disease in world. Although India is a leading contributor of World’s milk production along with increased consumption of milk and dairy products, only a few information is available on the prevalence status of Salmonella spp. in milk and dairy products. Hence the study was aimed to study the prevalence of Salmonella spp. and its antimicrobial resistance pattern by phenotypic methods that has been recovered from different study samples. Methods: Polymerase Chain Reaction (PCR) was adopted to confirm the Salmonella spp. and then phenotypically the antimicrobial resistance pattern was studied by Kirby Bauer disc diffusion method. Result: A total of 567 samples (75 Raw milk samples, 45 pasteurized milk samples and 447 dairy products) were screened and four Salmonella isolates which was derived from the dairy products were confirmed by PCR targeted the invA gene that encodes the invasion protein of Salmonella. The isolates showed multiple drug resistance and also has higher MAR indices along with 75 % resistance to the antibiotics viz, Cephalothin, Penicillin and Enrofloxacin. The presence of Salmonella spp. in milk and dairy products and their AMR to common antibiotics in the study area indicates that emerging resistance pattern of food borne Salmonella spp. and possibility of entering the food chain which is of high risk to the consumers.

Background: Production of microbial enzymes at the industrial scale and their commercialization has attained a lot of value and public focus. Usage of micro organisms as bio-reactors begins due to the evolution of enzymes produced by microorganisms. There are so many industrially significant enzymes are originated from microbes, that include pectinases, lipases, amylases, proteases, xylynases etc. Methods: The actual work involved the use of microbes isolated from the decaying orange peel and tomato pulp for the extraction of the pectinase enzyme. The organisms were isolated and screened from the samples and were cultured onto pectin agar plate. Morphological and microscopic identification revealed that the bacteria isolated was Bacillus sp. Pectinase production media was later used for the lab scale production of pectinase enzyme by inoculating the bacteria and incubating for 48 hours. The enzyme thus produced was purified by Various methods. The pectinase enzymes isolated from bacillus sp. were used for improvement of tea leaves quality and clarification. The enzymes were characterized and purified. Results: The outcome of both purified pectinase enzymes and crude enzyme preparation on the improvement of tea extracts were determined in terms of flavanoids (310mg/gm), DPPH (49mg/gm), caffeine content (0.56-0.95), moisture content (7.2-6.7%), ash (4.1-4.6%), total phenol content (285mg/gm), and pH(6) and the shelf life analysis of the tea produced. The results thus obtained can conclude that the use of Bacillus sp. in the industrial production of pectinase is highly beneficial. According to the findings obtained from the study the enzyme treated tea extract improves its various quality parameters than the tea extracts which is non enzyme treated. And the utilization of microbial pectinase produced from bio-waste were most cost effective and yield good results for industrial use.

Background: Jharkhand State Cooperative Milk Producers' Federation (JMF) plays a vital role in the processing of raw milk purchased from Jharkhand State member-producers and contributes to the development of the dairy sector. The current study explores the essential components in JMF's dairy supply chain, focusing on the marketing unit, and provides a preliminary framework for making decisions regarding its ramifications. Methods: To compile a SWOT analysis of the milk marketing system in JMF, data were collected from dairy producer members, including dairy farmers, marketing unit executives, and key informants. This includes establishing the objectives of the dairy sector and the internal and external critical factors (CFs). Because SWOT analysis does not give an investigative basis for evaluating the priorities of CFs, the analytic hierarchy approach is utilised to determine the priorities of detected CFs. The CFs have also been ranked according to their importance. Results: This study's findings indicate that the SWOT-based methodology gives crucial sensitivity when evaluating marketing chain strategy for dairy cooperatives like JMF. The findings of this study show that wide range of quality dairy products, absence of strong sales and marketing experience, emerging new markets offering greater marketing potential, seasonal slump are the major strength, weakness, opportunity and threat of JMF, respectively.

Background: Medicinal plants constitute an invaluable source of natural substances which can be used in the formulation of new antifungal agents. Among these medicinal plants, the genera Ephedra alata and Bubonium graveolens are used in traditional medicine. In the search for molecules bioactives, resource exploration natural, especially plants medicinal, appears as a track promising because they constitute, by their biodiversity, a great reserve of active substances. This study aimed to evaluation antifungal activity of medicinal plant extracts Bubonium graveolens and Ephedra alata against two fungi namely, Penicillium sp and Aspergillus niger. Method: During our work, we prepared the various extracts (aqueous, methanolic and ethyl acetate) for the plants studied, the search for the active compounds of these two species by the extraction method was essentially based. The antifungal tests were investigated by using agar medium methos The tests is estimated by determining the diameters of zone inhibition and growth inhibition rate PI %. Result: The results obtained show that the aqueous extracts of Ephedra alata and Bubonium graveolens are inactive against two fungi in our study. However, methanol and ethyl acetate extracts showed very good activity antifungal against the fungal species tested. The evaluation of the antifungal activity of the methanolic and ethyl acetate extracts had a higher activity (99,70 ±0,240) against all the molds tested compared to the aqueous extract (63,52 ±0,959). The extracts of Ephedra alata and Bubonium graveolens significantly inhibited the growth of the two fungi tested. These three extracts showed a good antifungal effect at the laboratory scale. Ours finding demonstrate that Bubonium graveolens and Ephedra alata extracts possesses antifungal activity that might be a natural potential source antifungal compounds used in pharmaceuticals products, cosmetics and food
