Influence of feeding cows with plant adaptogens on the physiological and biochemical status of lactating cows

Purpose: development of a method for correcting the physiological biochemical status of lactating cows and increasing their productivity in industrial stress conditions using vegetable adaptogens based on the sea buckthorn, hawthorn and lecithin.Materials and methods. The work reflects the results of a study on the effect of phytocompositions, including the fruits of sea buckthorn (SB), blood-red hawthorn (BH) and vegetable lecithin (L), on the physiological and biochemical status and productivity of lactating cows. The following groups of animals were formed, 5 animals each (n = 5), duration 30 days: group 1 (control) received only the basic diet of the farm (BD); Group 2 (BD + SB + BH) - the main diet of the farm, sea buckthorn fruits at a dose of 130 g / cow / day, blood-red hawthorn fruits dried at a dose of 40 g / cow/ day; Group 3 (BD + SB + BH + L) - the main diet of the farm, sea buckthorn fruits at a dose of 130 g / cow / day, blood-red hawthorn fruits dried at a dose of 40 g / cow / day, lecithin at a dose of 70 g / cow / day Revealed a positive effect on the indicators of protein, carbohydrate, lipid metabolism and milk productivity. By the end of the experiment, the experimental cows had the highest average daily milk yield in cows of group №. 3 that received, in addition to the main diet, a composition of hawthorn, sea buckthorn and vegetable lecithin (5.5% higher relative to the control group) and in group of cows №. 2 that received composition from the fruits of hawthorn and sea buckthorn (an increase of 4%).Results. Revealed positive effect on indicators of protein, carbohydrate, lipid exchanges and dairy productivity. By the end of the experiment, the experimental cows are the largest average daily fishing of the group of group No. 3, which additionally received the main diet from the fruits of hawthorn, sea buckthorn and vegetable lecithin (above 5.5% relative to the control group) and in the group of cows No. 2, which received the composition Of the fruits of hawthorn and sea buckthorn (the increase was 4%).Conclusion. The analysis of the results of the study of biochemical indicators shows that the composition comprising the fruits of sea buckthorn, hawthorn blood-red and vegetable lecithin has the greatest adaptogenic properties.

The performance of beeswax coating containing vegetable oil-based lecithin as an emulsifier on weight loss and shelf life estimation of mango

Fruits are one of the agricultural commodities grown in Indonesia and mango constitutes the third largest. One of the disadvantages in transporting mangoes to long distant markets is the short shelf life when fruits are stored at the room temperature. Some efforts to maintain quality and freshness have been coating the fruits with natural wax/beeswax. This study aimed to determine the effects of beeswax coating containing vegetable oil-based lecithin on physical and weight loss in mango, as well as estimate the shelf life using the Accelerated Shelf-Life Testing (ASLT) method. The coating formulation consisted of beeswax, triethanolamine, stearic acid, vegetable lecithin (soybean: rice bran), and water. Mango coated with beeswax coating with a concentration of vegetable lecithin emulsifier were varied at 0.25, 0.5, 0.75, 1%, and control (without beeswax coating) stored at room temperature 301oK and cooler temperature 286oK. Samples were monitored for five weeks and evaluated periodically for physical change and weight loss. Beeswax coated mango exhibited slower rate of ripening than the control stored in both room and cooler temperatures. The lowest total weight loss of mangoes at both temperatures for 5 weeks with beeswax coating at 0.25% vegetable lecithin emulsifier was 7.25%. The estimation of shelf life using ASLT method and Arrheinus model to mango fruit coated with beeswax coating at 0.25% vegetable lecithin concentration as emulsifier was 36.91 days.
