OPTIMIZING DAIRY CATTLE PERFORMANCE: THE IMPACT OF CONCENTRATE FEED AND MINERAL BLOCKS ON DENSITY AND MILK FAT CONTENT

Romziah Shafira

Read Abstract

This research investigates the impact of concentrate feed and mineral blocks on dairy cattle performance, with a specific focus on density level and milk fat content. Dairy farming is a vital component of the agricultural sector, and optimizing the productivity of cattle is of paramount importance. Through a comprehensive study involving controlled diets, this research assesses how the introduction of concentrate feed and mineral blocks influences cattle density and milk fat content. The findings shed light on practical methods to enhance dairy cattle performance, thus offering insights for farmers and the dairy industry.

THE EFFECT OF ACID CONCENTRATION ON THE DISTRIBUTION OF THE ELECTROLYTE BY SEPARATOR HEIGHT

A.Q. Mamatqulov, F.I. Erkabaev, N.Rashidova

Read Abstract

Various factors affect the performance of storage batteries and can reduce their performance. In practice, it is very difficult to realize the full use of active materials involved in the current generation process. About half of the active mass level does not participate in the reaction with the electrolyte, because they serve as the basis for making the electrode frame and ensure the mechanical strength of the materials. Therefore, the coefficient of real use of active materials of positive electrodes is 45-55%, and that of negative electrodes is 50-65%. In addition, a 35-38% solution of sulfuric acid is also used as an electrolyte. Therefore, the actual consumption of materials is higher than the theoretical consumption, and the actual energy volume is somewhat lower. The leakage of the electrolyte from the separator largely depends on its concentration. First, if the density of the electrolyte decreases, its weight decreases, which reduces its flow, but the decrease in density leads to a decrease in viscosity, which increases its fluidity. Therefore, it is desirable to determine the relationship between the concentration of the electrolyte, its distribution over the height of the separator and its fluidity during the experiment. This is a very important factor, as the electrolyte concentration changes after a certain period of time during battery operation, and the optimal concentration of the acid used as an electrolyte plays a major role in ensuring performance. In these studies, the effect of the concentration of the electrolyte used as a working electrolyte on the working efficiency of the batteries as a result of the increase in the pores of the separator and the change in fluidity at different compression levels was studied.

ADSORPTION PROCESSES FOR RESTORING TECHNICAL CHARACTERISTICS AND PROPERTIES OF USED OIL

Sh.T. Poyonov, S.M. Turabdzhanov

Read Abstract

The work carried out systematic research to create a technology for restoring the original properties of used oils. Adsorption purification of waste oils using the bentonite-vermiculite method was carried out. based on the use of the ability to retain oily contaminants penetrating through the outer surface and internal capillaries - the pores of the sorbent granules.
