Posted in 2019, AGRICULTURE, Issue № 10(88) October 2019 | 0 comments

Experimental samples based on strains of rhizospheric bacteria Bacillus subtilis: BZR 336g, BZR 517 and Pseudomonas sp. – BZR 245-F. The biological preparation of Extrasol was taken as a reference. The studies were carried out in field experiments on crops of soybean variety Primorskaya 13. As a result of the work, positive effect of laboratory samples on the morphometric parameters of soybean plants was noted. Bacterial strains in different combinations restrained the development of root rot. In the bean filling phase, drug samples reduced the development of the disease compared to the control by 8.5-17.4%. When using samples of drugs, the mass of 1000 seeds increased by 10.2 – 33.4% compared with the control group. The largest soybean grain formed during seed treatment and spraying plants of BZR 517 – 225.8 g (in control, the weight of 1000 seeds averaged 169.2 g). In this case, the soybean yield according to the experimental variants ranged from 2.8 (spraying plants BZR 336g) to 3.6 t/ha (complex treatment BZR 517), 2.6 t/ha in the control. The tests carried out within the work prove the viability of new bioagents as environmentally friendly plant protection products.

INFLUENCE OF CALVING EASE ON FERTILIZING ABILITY OF HIGHLY PRODUCTIVE COWS WITH REGARD TO THEIR MILK PRODUCTIVITY

Posted in 2019, AGRICULTURE, Issue № 10(88) October 2019 | 0 comments

The article presents the results of the research work aimed at establishing the effect of calving ease on the fertilizing ability of highly productive cows with regard to their milk productivity. The studies were carried out on the basis of the breeding farm SEC “Beregovoi” on 25 first-calf heifers and 35 cows of black-motley breed. It was found that bred heifers have difficult labour. The average score for the ease of calving of first-calf heifers was 3.04, which is 1.49 lower than for cows (P <0.95).

The percentage of successful fertilization of first-calf heifers was 64.0% including 20% from single insemination. Among cows of II and older calving, on average, in the group of pregnant animals, there were 30 animals, or 76.9%, of which 47.4% were of primary insemination.

Highly correlative relationship was found between the ease of calving and % of fruitful insemination of cows of I and II of lactation (r = + 0.50 and +0.47).

It was found that 57.1% of heifers and 44.8% of cows of II lactation and older became pregnant during 5 months of lactation, that is, with a decrease in daily milk yield by 26.0% in heifers and 32.7% in cows.

First-calf heifers, which were difficult to calve, are inferior in milk yield for 100 and 305 days of lactation when compared to animals with calving difficultly of 226.4 and 271.0 kg and the labour of which was very difficult – 612.2 and 959.0 kg (the difference is not significant).

Cows calving normally had milk yield for 100 and 305 days of lactation on 71 and 224 kg; 171 and 912 kg (P <0.95) less than calving animals the labour of which was difficult and very difficult.

Therefore, using the selection method, it is necessary to increase the ease of calving of highly productive cows, which will contribute to an increase in their fertilizing ability.

FACTORS AFFECTING FERTILITY OF HOLSTEIN COWS IN SAKHALIN REGION

Posted in 2019, AGRICULTURE, Issue № 10(88) October 2019 | 0 comments

The factors affecting the fertility of Holstein cows in the Sakhalin region were studied in this work. The main indicators characterizing the effectiveness of reproduction include the following: calf yield, calving and service periods. The 365-day interval is considered to be optimal, since it is most beneficial in terms of milk yield and profitability of milk production. An increase in the calving interval over 365 days leads to increase in the costs of insemination, veterinary services and naturally reduces the rate of economic improvement of the herd. The data obtained over the entire period of the study showed that the cows-daughters of the manufacturing bull Zhemchug 48939 of the related group Vis Bek Aydial 1013415 exceeded their peers in the main indicators of fertility.

WAYS TO IMPROVE TAXATION INDICATORS OF FOREST FUND OF KAZAKH HILLOCKY AREA

Posted in 2019, AGRICULTURE, Issue № 10(88) October 2019 | 0 comments

The increase in forest productivity (IFP) is a topical task of modern forestry. IFP measures should be based on the objective description of the forest fund. The authors analyze the main taxation indicators of the forests in the Kazakh hillocky area on the example of the forest fund of the Kokshetau region based on databases of forest inventory materials. It must be noted that, despite harsh forest growth conditions, the forest fund is dominated by lands covered by forest vegetation – 67.8%. The artificial plantations account for 11.4%, and 50.2 thousand ha (11.5%) are not covered with forests.

Lands covered with forests are mainly represented by birch forests, pine forests and aspen forests, which account for 54.1; 33.7 and 9.9%. At the same time, 1.5 thousand hectares (0.5%) are occupied by purple osiers, and 0.8 thousand ha (0.3%) are occupied by shrubbery. However, 14.6% of birch forests, 20.4% of common aspen trees, as well as all purple osiers and shrubs, are ripe and overmature.

In order to increase the productivity of the forest fund, forest crops should be planted on non-forested lands, as well as subordinate crops in low-density plantings. Increase the proportion of pine trees due to derivatives of birch forests and aspen, as well as shrubbery. Wider practice the introduction of introducers to expand biological diversity, increase the stability of plantations and their productivity.

Posted in 2019, AGRICULTURE, Issue № 10(88) October 2019 | 0 comments

Research on the study of adaptive abilities on high-blood cows and first-calf heifers of black-and-white breed were carried out at the Beregovoi Agricultural Production Cooperative. It was noted that during the milking of the first-calf cows and of the 2nd and older calving, cows showed the highest daily milk yield during the 2nd month of lactation followed by a decrease in milk yield by 5% in first-calf heifers and by 7% in full-age cows. The maximum fat content in milk was noted during the 3rd month of lactation, both in cows of II calving and older (3.94%) and in first-calf heifers (3.84%). The influence of the transfer of cows from three-fold to two-fold milking and a change of workshop was established. Changing the milking rate after 100 days of lactation affected milk productivity negatively while switching to 2-fold milking reduced the daily milk yield in cows of the first calving by 16.2%, and in cows of II lactation and older by 21.5%, and the fat content in milk has decreased. Cows with high daily milk yield behaved excitedly, were worried by the time of lunch milking, on the 5th day after the transfer, an excited state was observed in 15% of older cows and 10% of first-calf heifers. Transferring cows to another yard affected their respiratory rate, in first-calf cows it increased by 12.2 times per minute after the transfer, while in full-aged cows it rose by 8.69 times per minute; the difference was 8.0 times per minute and 5.24 times per minute, respectively. After the transfer, the cows of I, II, and II and older calving reduced the daily milk yield by 5.59 and 9.0 kg, therefore, the profit received was lost by 203.50 and 302.50 rubles. Under the conditions of this household, further work on adaptive breeding should be carried out to identify individual characteristics of cows and their adaptability to technology.

Posted in 2019, AGRICULTURE, Issue № 9(87) September 2019 | 0 comments

A method for the cultivation of Coccinellidae on artificial nutriculture media (ANM) is proposed allowing the simplification of the technology and the reduction of the cost of mass breeding of entomophages without reducing biological indicators, whereas data on the biological efficiency of entomophages raised on ANM in relation to aphids and mealybugs are presented.

The consumption of natural feed is reduced by 25-85%; sucrose by 17-20%, amino acids by 23-27% in developed artificial nutriculture media for Coccinellidae. A cheaper and more technologically advanced component, soy flour, was introduced into the composition of the media instead of casein. Palm oil was introduced instead of corn and coconut oils with a longer shelf life, which is especially important in a microclimate bio-laboratory environment, the media enriched with vitamins B1; AT 6; AT 12.

As a result of the studies, it was found that the biological efficiency of entomophages raised on ANM does not differ from the biological efficiency of those raised on natural food.

EXPERIENCE OF CREATING ARTIFICIAL PLANTINGS IN DRY SHEEP FESCUE FEATHER-GRASS STEPPE OF NORTH KAZAKHSTAN

Posted in 2019, AGRICULTURE, Issue № 9(87) September 2019 | 0 comments

The experience of creating artificial plantings of Siberian elm (Ulmus pumila L.), Scots pine (Pinus sylvestris L.) and drooping birch (Betula pendula Roth.) under the conditions of dry sheep fescue feather-grass steppe of Northern Kazakhstan is analyzed. It is established that Scots pine and drooping birch can create stable long-term plantings on forest-suitable soils even under extreme forest conditions. At the same time, Siberian elm, which is widely recommended in the scientific literature for afforestation under arid conditions, forms short-lived plantings and the conservation of viscous trees is possible only with systematic rejuvenation by “planting” trees on a stump. In the absence of silvicultural care, Siberian elm dries, dramatically reducing the aesthetic appeal of the created plantings.

ANALYSIS OF USAGE OF DOMESTIC AND FOREIGN SELECTION OILSEED

Posted in 2019, AGRICULTURE, Issue № 9(87) September 2019 | 0 comments

The introduction of highly productive oilseeds, reducing the level of dependence on varieties of foreign selection is considered to be one of the key tasks for the implementation by the Federal scientific and technical program for the development of agriculture for 2017-2025. Oilseed crops in the Russian Federation reach about 15% of all sown areas, but three oilseed crops dominate, these are sunflower, soy, and rape. Even though the cost of a sowing unit of sunflower seeds of a foreign hybrid significantly exceeds the cost of a sowing unit of sunflower seeds of domestic selection, a consumer chooses foreign varieties. The article analyzes the use of oilseeds of foreign selection in the production of sunflower, soybean, and rapeseed and compares the main indicators based on the results of tests in the Russian Federation of sunflower varieties of domestic and foreign selection.

DEPENDENCE OF THE FERTILITY OF COW-HEIFERS ON THE AGE OF CALVING AND BODY WEIGHT

Posted in 2019, AGRICULTURE, Issue № 8(86) August 2019 | 0 comments

It is known that the age of the first fruitful insemination and calving of young animals has a certain effect on subsequent productivity and manifestation of the main breeding traits.

The variability of indicators of fertility in cows is mainly due to paratypical factors, which suggests a low level of their heritability. General development of animals for the period of the first fruitful insemination and calving, which is characterized mainly by their live weight, has a significant impact both on the level of signs of milk production and on the reproductive qualities of Holstein cows. As a result of the research, it was found that animals with a mass up to 500 kg at the first calving have the best reproductive qualities.
