Histological Characteristics of the Skin and Cuticle of the Wool Fibers in Dubska Pramenka and the Use in Industry

Microscopic analysis of the skin and cuticle of wool fibers in Dubska pramenka show different qualitative parameters. The research study included different parts of the body and the samples of the wool fibers from different regions of the body. Histological description shows difference in the basic structurers of the skin in Dubska pramenka. A very pronounced thin epidermis, while dermis and hypodermis are more developed on the samples from the shoulder. Cornified flakes-cuticle of the root of the tail was of a fine structure, and cornified flakes from the rump showed the features of the rough wool fibers. “Transitional form of cuticle” was dominant on the shoulder. The qualitative parameters have a significant influence on the overall quality of wool in general, and the research contributes to a greater usability value of the wool and development of livestock farming in areas in a broader sense.

Effect of probiotics on body conformation of the fattening chickens.

The possibility of using different probiotic products primarily in animal food represents a special direction in the modern production of broiler meat. Intensive broiler production has been improved in the last few decades especially in the fields of genetics, nutrition and technology, in order to achieve maximum growth broilers, the optimal utilization of food and high yields, especially white meat. Considering the above mentioned research was conducted in order to examine the impact of commercial probiotic products on the body conformation of the carcasses of chickens after 42 days of fattening. In experiment was used a total of 30 chickens provenience Cobb divided into two groups (P and K). Chickens from both groups were vaccinated according to the plan and program of immunoprophylaxis, and selected technical and technological solutions of accommodation, as well as feeding and watering chickens were in accordance with the recommendations of the selectors for the floor system rearing. Chickens of experimental group (P) were given in drinking water, a commercial probiotic Probios ®, a soluble powder for poultry, product of a company Chr. Hansen A / S, Denmark. Probiotic treatment of experimental groups of chickens was conducted the first three days of life and three days during the vaccination of chickens (the day before, on the day and the day after vaccination). Measures of body conformation (the breast circumference, keel length, breast depth, drumsticks circumference, shank length and breast angle) were determined on carcasses after the fattening of 42nd day using standard tools in livestock breeding. The results obtained from this study suggest that the usage of commercial probiotics in broiler chickens in intensive fattening has proved to be statistically significant on tested measure of body conformation.
