Scientific work

In 2014 one research topic was carried out at the department:

 1. “Theoretical foundations development for monitoring performance of pets’ breeding resources in Ukraine” (№ 110 /61 -f ) Supervisor – V.I. Sheremeta, Dr. Sc., professor. The total amount of money is 140 thousand  hryvnyas.

 Training and teaching staff of the department performed the scientific work on 3 initiative topics that are of state registration:

 1. Species features of spontaneous and induced somatic mutagenesis of pets (0111U006756) Head of research - Kostenko S.A., Associate Professor

2. The influence of candidate genes for economic value of domestic pig (0107U007936) Head of research - Kostenko S.A., Associate Professor

 3. Method improvement on artificial breeding of queen bees families’ educators (0109U0071059) Head of research – V.I. Sheremeta, Professor. Responsible performer - Vedmid I.V., graduate student

 Key indicators of research

Four methods are identified, the use of which provides the definition of the true origin of breeding animals; identify the individuals carrier of hidden genetic defects; of selection marker (MAS- selection) in dairy cattle herds. Genetic control methodology has been established on the course selection process in herds of cattle on the frequency dynamics of marker genes.

 The effective schemes of cows and boars’ reproductive ability had been elaborated using biologically active drugs of neurotropic and metabolic action “Glyutam 1M”, “Stymulin Vet”, ‘Shans” and “Yantargin”.

 The most important results on the priority areas of research are the following:

According with conducted at the chair scientific researches was established, that application for cows under the skin of drug action “Glyutam 1M”, in dose of 20ml once a day during 265-267 and 270-272 pregnancy days increases by 7.7-42.8% (р<0,05) cows fertility after first insemination, reduces service period by 7.9-38.9 days (р<0,001) and reduces insemination index by 0.2-0.7 (р<0,05).

New biological active drugs “Yantargin” and “Shans” was created. Their applications promote rapid familiarizing of replacement boars with dummy and stimulate semen production of boars during different usage schemes, namely incise the ejaculate volume from 7.5% to 29.1% (р<0,05) and semen concentration from 9.5% to 22.5%/

Control system on the basis of DNA technology had been developed and reasonable sequence of these methods had been established including the efficiency determination of dairy cattle breeding, improvement of milk production to increase fat and protein in milk and improves its technological properties.

It had been established that among 30 sows in NRS “Agronomic research station” only 4 had the desired genotype BB for estrogen-receptor gene, 25 of which were heterozygote. All investigated boars were also heterozygous. This shows that a quarter of their offspring will have a low reproductive capacity because of sow’s heterozygosis.

A method of queen bees’ selection had been developed on the basis of feeding with the created bioactive feed Hlyutam 2BM during embryonic period.

A method for increase of ostriches’ egg production had been elaborated on the basis of the species evaluation and selection with the highest egg production for the first 4 weeks of the reproductive season, which will reduce the interval between their generations for 1 year and the growth rate of breeding to improve their egg production by 0.2 eggs per year. Selection process acceleration is provided for the increase of ostriches’ egg production by 0.2 eggs per year for one population with the regular use of a new method.

Student scientific circles are always being functioned at the department. On the results of the scientific research students make reports at the faculty conferences, other institutions and higher educational establishments.
