Grain yield stability analysis using AMMI and GGE biplot models in different breeding zones of Bangladesh

During the 2018-2019 Boro season (dry season), 70 rice genotypes were examined with alpha lattice experimental design with the goal of measuring grain yield stability analysis. Results indicated that AMMI analysis explained 100% of the G×E variance, while captured 81.74% variance. Based on the GGE and AMMI analysis, the most stable and high yielding genotype was identified G41 followed by G22, G26, G58, G24 and G61. The AMMI 1 biplot analysis revealed that the first primary component of interaction (IPC1) factor was responsible for 64.2 % variation due to G × E interaction. On other hand, the second primary component (PC2) factor accounted for 35.8% variation of the G × E interaction. These two-primary component (PC1 and PC2), all together accounted for 100% variation of the G × E interaction. The contribution of G68 was highest to the interaction followed by G70, G58, G42, G61, G45, G38, G14, G33, G60, G53, and G9. Best environment analysis indicated that the ranking was Rajshahi < Gazipur < Cumilla. GGE biplot analysis accounted for 81.74% variation comprising two principal components PC1 and PC2 with 45.62% and 36.12% variations respectively. Rajshahi was more stable than Gazipur. Based on environment analysis genotypes, G22, G26, G58, and G44 can be recommended as best stable genotypes that breeding zone. However, the genotype G61 was identified adapted to Cumilla breeding zone.

PSXV-3 The influence of the dams genotype on the indicators of the breeding value of offspring

Aberdeen Angus cattle of Australian breeding is a new ecological and genetic genotype and it is currently in the process of formation and differentiation, the genealogy of the breeding stock is represented by the leading related groups of bulls-leaders of domestic and imported breeding. The aim of this work was to study the breeding value of Bismarck5682bovine cows of Australian selection (n = 20) and Design1015 (n = 20) of domestic reproduction of the Aberdeen-Angus breeding and their influence on the selection and genetic parameters of the productivity of heifers-daughters. It was revealed that the representatives of the Design line had an advantage in live weight (615.4 kg,lim-705-495kg) by 9.8% (P &lt; 0.001), milk productivity (219.7 kg,lim-241-184kg) by 2.4% (P &gt; 0.05) and height insacrum (134.5 cm,lim-140cm-128cm) by 4.1% (P &lt; 0.001) compared to peers of Bismarck line.The ability of animals to realize their breeding potential is determined by many factors. So, it was revealed that the heifers of Design lineexceeded their peers from Bismarck group in live weight in 15 months (359.8 kg, Cv-5.24%) by 5.2%, (P &gt;0.05), average daily gain (652.8 g, Cv-7.86%) - 10.6% (P&lt; 0.001), body conformation score (19.7 points, Cv-3.72)- 14.5% (P&lt; 0.01). It should be noted that heifers – daughters of the Bismarck genealogical line gave in sacrum height but had a better estimate of meat forms by 2.9% with reliable values. These results allow us to conclude that the offspring of the Bismarck 5682 genealogical line of Australian breeding are more affected by the negative factors of the new breeding zone. Thus, a step-by-step selection evaluation of the breeding stock will allow more reliable identification of breeding bulls with a better ability to improve valuable distinguishing features in the generations of cows during their linear breeding. The research was carried out within the framework of RAS 0526-2021-0001.

Features of the physical and chemical characteristics of water of energy facilities for aquaculture tasks

Energy facilities and water are inextricably linked. Accordingly, the issue of water quality, its transformation as a result of industrial use of energy facilities and the assessment of further use for aquaculture purposes is an urgent task of our time, especially in relation to weather and climate risks for industries. The article provides a classification of water according to the water supply technology of energy facilities by temperature factor and the possibility of using it for aquaculture tasks. In total, three classes of water are distinguished according to the temperature factor: waters with natural physical and chemical characteristics, where the temperature regime of reservoirs corresponds to the geographical zone in which the reservoir is located (cultivation of fish associated with fish-breeding zone in which the reservoir is located); water of bassin-coolers of energy facilities, characterized by the presence of a zone of increased temperatures as a result of the discharge of heated water (organization of flood-proof farms with polycyclic production); water of cooling ponds (cultivating fish capable to the fight against eutrophication).

Statistical evaluation and forecasting of human resources support by specialists and workers of mass professions of agricultural organizations of the grainsheep-breeding zone of Stavropol region

Improving the efficiency of agricultural production and the competitiveness of agricultural products is impossible without the creation of professional teams with a high level of productivity. The formation and development of the personnel potential of the agro-industrial complex comes to the fore in the light of ensuring the country’s food security and solving the problems of import substitution. The development of the industry relies more on the creation of a vertical education system, the development of rural territories, etc. Compilation of forecasts for the staffing of the agroindustrial complex will coordinate the efforts of educational institutions, business structures, and authorities in organizing the training and retraining of personnel for the agricultural sector.

Results of a comparative study of the use of fodder worms of two breeds for pool growing of young tilapy and clary catfish in the conditions of the Almaty

The aryicle presents the results of a comparative study of the biochemical composition of earthworms of dendrobene and prospector rocks, the peculiarities of their cultivation and their use for feeding when growing juvenile tilapia and clary catfish. The experience of cultivating earthworms of two breeds using the improved methods of foreign authors is described. The results of a study of the biochemical composition of cultivated objects that determine their nutritional value for feeding fish are presented. The fish-breeding and biological indicators of juvenile tilapia and clary catfish, obtained during the cultivation of dendrobene and prospector in fish farming in the Almaty region (VI fish-breeding zone) during worm feeding, are analyzed. A comprehensive analysis of the studied indicators made it possible to assign a certain rating place to each worm breed in relation to its use as fish feed.

THE INFLUENCE OF THE GENOTYPE OF STUD BULLS OF HOLSTEIN BREED ON THE LEVEL OF SOME INDICATORS OF NITROGEN METABOLISM OF OFFSPRING IN WESTERN SIBERIA REGION

The results of studies of indicators of nitrogen metabolism in the blood serum of the descendants of four bulls at the age of 12-13 months are presented. The studies were conducted in the South of Western Siberia at Vaganovo OJSC on the livestock population of Holstein breed. The creatinine concentration in the blood serum samples of the sons was determined using a set of reagents from Vector-Best (Russia). In the regions of animal breeding, constant monitoring of water, soil, feed, animal organs and tissues is carried out. It was established that in the areas in which the studied breeds were bred, the content of macro- and microelements did not exceed the MPC. The level of serum creatinine in the examined animals on average for all groups of sons was 308.2 ± 24.1 μmol / L, which exceeds the generally accepted values of this indicator. However, taking into account age and sex and breed characteristics, taking into account data on the overall health of the animals examined, information on the ecological well-being of the breeding zone, the results can be considered as reference values for healthy Holstein bulls in Western Siberia. It was shown that in the blood serum of the sons of some fathers, the creatinine content was 1.7 times higher (364.2 ± 52.7 μmol / L) than in the descendants of other manufacturers (p> 0.95). A group of half-siblings was found, which were characterized by a low hereditary predisposition to creatinine content. Discovered differences in the creatinine content in the blood serum of sons reflect the differentiation of bulls and indicate genetically determined features of the functioning of the homeostasis system. In this case, most likely, there is a different ability of descendants to adapt to environmental and climatic conditions.

Changes in live weight and biochemical blood indicators in Tyvan short-fat tailed sheep breed depending on the breeding zone and season of the year

The considers the research results of productive qualities and biological features of Tyvan short-fat tailed sheep breed depending on the season of the year and the breeding zone of the Republic of Tyva: mountain taiga-steppe, desert-steppe and dry steppe. The highest live weight was observed in sheep raised in the dry steppe zone. When studying the biochemical composition of the blood of sheep in the summer-autumn grazing period, the content in the blood of sheep of the compared groups of basic biochemical parameters is within the physiological norms. In the winter-spring period, when grazing sheep on rags of last year’s grass due to a deficiency in their diets of basic nutrients, the blood levels of animals of all groups of total protein, calcium and reserve alkalinity are below physiological norms.

Bioproductivity of ponds of VI fish breeding zone

The paper highlights the prospects of cultivating heat-loving species, such as Australian crayfish and freshwater shrimps in the VI fish breeding zone. Australian crayfish and freshwater shrimps breeding is considered economically attractive for entrepreneurs, having a limited area for farming facilities. At the same time, pond ecosystems require the individual approach and close study in terms of the environmental conditions for the cultivated species upkeeping and the natural forage base that determine the pond biological productivity. Today, there are no clear recommendations on the summer keeping warmwater aquaculture species, in particular, Australian crayfish and freshwater shrimp in the Astrakhan region. To cultivate the new objects of warmwater aquaculture in 2017-2019 the small innovative enterprise Modern Sharapovskiy Fish Breeding Complex researched the production potential of ponds of various categories for receiving marketable products; there was studied the forage base, biomass of zooplankton and zoobenthos satisfying the nutritional needs of farmed objects. As a result of experimental work, it was found that in pond No.2, where freshwater shrimps were grown, there were registered 5 species of Cladocera and 1species of Rotifera, while in pond No.1 used for breeding Australian crayfish there were registered 4 species of Rotifera and only 1 species of Cladocera. Presumably, the observed species composition of the studied ponds is specified by the selectivity of the cultivated objects in zooplankton consumption. The possibility of increasing the bio-productivity of ponds by alternate growing aquaculture and agricultural products has been considered.
