The investigations have been performed<br />in terms of producing activity of the cattle breeding farm of the Moldova’s south districts, using a group of Black<br />Spotted cattle breed population of Moldavian “south” subtype. It wasn’t established a regularity of the influence of the<br />first insemination age on the reproductive indices and milk productivity level of the primiparous heifers of the Black<br />Spotted cattle breed of Moldavian “south” subtype. The reduction of cow reproductive indices takes place only when<br />milk productivity level exceeds 7000 kg per normal lactation compared with the maximum allowed requirements. The<br />length of the service-period increased by 46,25%; The length of the calving interval increased by 3,97%; The<br />coefficient of cow reproductive capacity decreased by 1 %. The value of the main reproductive indices of the studied<br />group of cows manifested specific features depending on the season: The intensity of estrum manifestation prevails in<br />the spring-summer period and constitutes 69,57% of the total females in heat during the year; The length of the serviceperiod<br />exceeds the maximum allowed requirements in the autumn-winter period; The best results of female fecundity<br />have been established in the autumn and spring periods.</p></cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2012T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2012T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-26283</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-39466</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2012T24:00:00</cfStartDate> </cfPers_ResPubl> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-26283</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-26283-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012T24:00:00</cfStartDate> <cfFamilyNames>Granaci</cfFamilyNames> <cfFirstNames>Vera</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-39466</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-39466-3</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2012T24:00:00</cfStartDate> <cfFamilyNames>Morari-Pirlog</cfFamilyNames> <cfFirstNames>Alisa</cfFirstNames> </cfPersName_Pers> </cfPers> </CERIF>
