The Effect of Feeding on the Expression of the Hereditary Opportunities of Monbelyard Bulls Belonging to Different Genotypes

Sh. N. Madrahimov — 2023-09-11

In the researches, the live weights of Montbeliard bulls of different genotypes fed under the same feeding conditions, the average daily growth indicators, the quantity and satiety of consumed feed, and the features of covering feed with live weight are presented.

As a result of feeding the bulls in the experiment on the basis of a full-value and standardized ration under the same conditions, group II (½ Aberdeen-Angus x ½ Montbelyard),Group III (½ Limousin x ½ Montbelyard) and Group IV (½ Charolais x ½ Montbelyard) F1 hybrid bulls are equalCompared to bulls of group I (pure Montbelyard breed), it was observed that during the experiment, they used feed efficiently. As a result, 39.2 kg or 8.7%, respectively, compared to pure Montbelyard breed equals (P<0.001); 28.5 kg or by 6.3% (P<0.001) and by 18.0 kg or 4.4% (P<0.01) had a high absolute weight gain and an average of 8.13 per kg live weight gain for bulls; 7.51; 7.68 and 7.86 feed units were consumed or F1 hybrid bulls 0.62 (7.6%) compared to their peers, purebred Montbelyard bulls, respectively; 0.45 (5.8%) and 0.27 (3.4%) units of feed were consumed less, which showed that full-value feeding is integral to the full development of the genetic potential of F1 hybrid bulls obtained from direct industrial breeding.

Distribution of Hydrophobic Composition in the Structure of Leather and Use of the Composition Possibilities Study

Djuraev Abdujalil Mannapovich — 2023-09-26

In the context of intensified competition in the global shoe markets, the domestic footwear industry is faced with the task of developing and producing competitive leather waterproof shoes with improved consumer and performance properties. The desire to create comfortable, lightweight shoes that would bring pleasure from walking and improve the quality of life of people is the "philosophy" of the modern shoe industry, and genuine leather, which most fully meets the operational, hygienic and aesthetic requirements for shoes , will remain the main one for a long time. Material in its production. During wear, shoes are exposed to all kinds of atmospheric, mechanical and chemical influences, which worsens their operational and aesthetic properties. Maintaining the quality of the product during operation is another equally important task. The use of various shoe care products (water-repellent emulsions and creams) makes it possible to make the materials of the external parts of the shoe upper temporarily waterproof. The question of the effectiveness and principle of choosing "cosmetics for shoes" with a satisfactory price-quality ratio remains open to date.

Assessment of the Quality Indicators of Threads Obtained by an Improved Method from Mixtures of Fiber and Secondary Material Resources with Different Compositions

Yodgorova Hilola Isroilovna — 2023-09-26

in this article, "Safira-Samira textile" LLC and "OYGUL PLUS" LLC in Bukhara produce yarn and fabrics used for technical purposes from 100% secondary material resources of knitting scraps from 80 tex yarns. And in our research work, the secondary material resources of 66.4% cotton fiber with 27.0% viscose fiber + 6.6% nitron fiber for jute yarn, 66.4% cotton fiber with 27.0% lavsan fiber + 6.6% nitron fiber secondary material resources, 66.4% cotton fiber with 27.0% nitron fiber+6.6% cotton fiber secondary material resources, 66.4% cotton fiber with 27.0% lavsan fiber+6.6% viscose fiber secondary material resources, 66.4% cotton fiber with 27.0% viscose fiber + 6.67% lavsan fiber secondary material resources from a mixture of 66.4% cotton fiber with 27.0% cotton fiber + 6.6% viscose fiber secondary material resources 29.4 tex yarns were produced and their physical and mechanical properties were determined using modern equipment in the Uster Tester-5 test laboratory at the UZTEX TASHKENT LLC enterprise.

The Effect of the Mixture of Different Composition and Recycled Fibers on the Single-Cycle Tensile Deformation of Gases

Rajapova Umida Baxtiyarovna — 2023-09-26

in this article, 5000 tex pelts were made on the JFA-226 carding machine at the production enterprise, 3 types of pelts were made on the HSR-1000 type pelting machine in the laboratory of TTESI under the "Spinning Technology" department, JAT of the Japanese company "Toyota" in the laboratory under the "Textile Fabric Technology" department On the 810 loom, yarn made of 100% cotton fibers was thrown into the warp thread, and yarn mixed with secondary fibers was thrown into the loom yarn.

Synthesis of Aminocompounds

Kultaev Kuzibay Kazakbaevich — 2023-09-28

In the article formation of aminoalcohols and aminocompounds by Mannich reaction from acetylenic alcohols and phenylacetylene have been investigated. Acetylenic alcohols were synthesized by the reaction A.E. Favorsky and phenyl-acetylene was obtained from styrene. The influence of various factors (temperatu-re, catalyst, time and nature of solvents) on the yield of aminoalcohols was studied. A theoretical analysis of the mechanism of formation of acetylenic aminoalcohols is given. The physicochemical properties of the synthesized aminoalcohols and their yields were determined. The chemical structure of aminoalcohols has been confirmed by IR and PMR spectrums.
