Ecological-Faunistic review of Gastropoda (Cuvier, 1795) representatives under the Vologda region conditions
Data on species composition of fresh-water mollusks, representatives of Gastropoda (Cuvier, 1795) under the conditions of the Vologda region are provided. 27 types relating to 10 childbirth: Aplexa (Fleming, 1820), Physa (Draparnaud, 1801), Lymnaea (Lamarck, 1799), Anisus (Studer, 1820), Armiger (Hartmann, 1840), Planorbis (Geoffroy, 1767), Segmentina (Fleming, 1818), Bithynia (Leach, 1818), Valvata (O.F.Müller, 1774), Viviparus (Montfort, 1810) are determined. Dominating look is Lymnaea truncatula, Müller, 1774. The main groups of biotopes are defined.
Ethological individuality as a sign of ayrshire cattle breeding
Studies having been carried out on animals of Ayrshire breed show that indexes of food, motion and total activity selection can be successfully used as selection signs. Selection of cows on ethological individuality is accompanied by an increase of their milk production. Animals with increased food activity, compared to cows with a low one, have got the rise of milk yield per lactation by 686 kg. Ultra-active cows should be mentioned particularly, productivity of them opposite to infrapassive ones increases by 49%.
Chlorella suspension use in feeding yield heifers of blackand white breed in milk period growth
The article gives the results of studying on chlorella suspension influence on the yield heifers of black-and white breed. It has been established that feeding crop additions to animals in milk period growth of 0,5kg per head during twenty-four hours brings an increase in average daily gain, feeding activity of heifers along with health conditions optimization.
Developing fertilizer system for lawn grass stands
This paper is the result of studying the peculiarities of mineral nutrition of lawn grass stands established on the basis of perennial bottom meadow grasses. In this work the assessment of the main mineral nutrients removal by the top mass of lawn plants during the whole growing season and for each mowing cycle has been given, the doses of mineral fertilizers for each experimental option in active substance and in physical weight have been defined.
The quality of bulky feeds on the farms of the Vologda Region
The article presents the results of studying the chemical composition and quality of forage harvested on farms of the Vologda Region. As a result of detailed analysis of roughages and succulents nutritive value it has been revealed that regarding metabolizable energy and crude protein they insufficiently meet the needs of highly productive animals. The proportion of the 1st and 2nd class fodders in 2014 was as follows: 14.1% of hay, 38.5% of haylage, 44. 8% of silage. The analysis of the received data on the nutrients content in roughages and succulent fodders allows to find the causes of their low quality and plan their elimination in the future.
Methodical approaches to the use of laying hen forced molting
The analysis shows various methods of hen forced molting used in different farms. The methods used nowadays allow increasing the lifetime of laying hens, reducing the duration of molting and identifying stress resistant hens.
The causes of the disposal of the animals and the main milk productivity indices of cows having different genotypes depending on the method of housing and technology of milking
The causes of the disposal of the animals and the main milk productivity indices of cows having different genotypes depending on the method of housing and technology of milking have been analyzed. For all the evaluated periods the animals which were milked with a robotic system in the free stall barn surpassed the cows which were kept on a leash and milked into the pipeline with the help of milking machines. Along with this, in the cows kept in the free stall barn the limb diseases caused culling more often than in other groups of animals under study.
Comparative characteristic of methods for the preparation of muscle cuts for compressor trichinoscopy
The article consideres the methods for the preparation of the tests for the compression trichinoscopy. It gives the results of the determination of the most effective methods to prepare the muscle cuts for the compression trichinoscopy diagnosis.
An alternative replacement for traditional preserving agent in dairy industry
In the laboratory rekombination method samples of concentrated milk product with sugar and malt extract were produced. The developed product was analyzed for physical and chemical, organoleptic and microbiological quality indicators. Besides the vitamin, mineral and carbohydrate composition of concentrated milk product with replacement of 10 % sucrose on malt extract was studied. It was established that the vitamin content increases by 6-9 times, minerals 1.5-3 times. Introduction of malt extract leads to diversity of the carbohydrate profile of the developed product.
