The reduction of labour costs is very important for the milk production and it must be reasoned scientifically. The impact of the milking frequency on the milk yield, depending on the productivity level, is of great interest. The aim of our research was to study the milking regimes under different breeding conditions. In order to study the productivity indicators at various milking regimes we have chosen the following parameters: the duration of lactation, milk yield per year, month and day, the qualitative composition of milk, based on the data obtained by means of the «TOTAL Ekomilk» Ultrasonic Milk Analyzer. We performed control milking operations during four days according to two milking schemes: twice or three times per day. It wasn’t recorded a significant impact of the milking regime, but in 2012, the best performance was observed under the following milking regime: at 7.30 in the morning, at 1.30 in the afternoon and at 7.30 in the evening. The distribution of the
milk obtained per day is as follows: 45% - in the morning, 31% - in the afternoon and 24% - in the evening. The highest milk yield is observed in the 3rd – 5th month of lactation – 12-14 kg of milk, the lowest one – 4-7 kg of milk in the 10th month of lactation. We have found out that if a cow produces 5-6 liters of milk per day, it needs 4 days to restore the milk yield after the transition from milking cows three times per day to milking them twice per day. |

Актуальным является влияние кратности доения коров на удой в зависимости от уровня производительности. Целью исследований является изучение режимов доения коров при различных способах содержания. Для изучения показателей производительности при разных режимах доения коров нами выбраны следующие показатели: продолжительность лактации, удои за год, месяц и сутки, качественный состав молока, по данным исследования на ультрозвуковом анализаторе молока «TOTAL Ekomilk» Проведены контрольные дойки коров в течение четырёх дней по трёхкратной и двукратной схеме доения. Значительного влияния режима доения не установлено, но лучшие показатели за 2012 год при режиме доения: утро – 7-30, обед – 13-30, вечер – 19-30. Распределение надоенного молока за сутки составляет: утро – 45%, обед – 31%, вечер – 24%. Наивысший удой приходится на 3-5 месяц лактации –12-14 кг молока, самый низкий показатель за 10 месяц лактации – 4-7 кг молока. Изучено, что при надоям 5-6 литров молока в сутки необходимо четверо суток для восстановления надоев после перехода из трехкратного доения на двукратное.</cfAbstr> <cfResPubl_Class> <cfClassId>eda2d9e9-34c5-11e1-b86c-0800200c9a66</cfClassId> <cfClassSchemeId>759af938-34ae-11e1-b86c-0800200c9a66</cfClassSchemeId> <cfStartDate>2014-04-01T24:00:00</cfStartDate> </cfResPubl_Class> <cfResPubl_Class> <cfClassId>e601872f-4b7e-4d88-929f-7df027b226c9</cfClassId> <cfClassSchemeId>40e90e2f-446d-460a-98e5-5dce57550c48</cfClassSchemeId> <cfStartDate>2014-04-01T24:00:00</cfStartDate> </cfResPubl_Class> <cfPers_ResPubl> <cfPersId>ibn-person-43928</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2014-04-01T24:00:00</cfStartDate> </cfPers_ResPubl> <cfPers_ResPubl> <cfPersId>ibn-person-43929</cfPersId> <cfClassId>49815870-1cfe-11e1-8bc2-0800200c9a66</cfClassId> <cfClassSchemeId>b7135ad0-1d00-11e1-8bc2-0800200c9a66</cfClassSchemeId> <cfStartDate>2014-04-01T24:00:00</cfStartDate> </cfPers_ResPubl> </cfResPubl> <cfPers> <cfPersId>ibn-Pers-43928</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-43928-1</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2014-04-01T24:00:00</cfStartDate> <cfFamilyNames>Варпиховский</cfFamilyNames> <cfFirstNames>Р.</cfFirstNames> </cfPersName_Pers> </cfPers> <cfPers> <cfPersId>ibn-Pers-43929</cfPersId> <cfPersName_Pers> <cfPersNameId>ibn-PersName-43929-1</cfPersNameId> <cfClassId>55f90543-d631-42eb-8d47-d8d9266cbb26</cfClassId> <cfClassSchemeId>7375609d-cfa6-45ce-a803-75de69abe21f</cfClassSchemeId> <cfStartDate>2014-04-01T24:00:00</cfStartDate> <cfFamilyNames>Яремчук</cfFamilyNames> <cfFirstNames>А.</cfFirstNames> </cfPersName_Pers> </cfPers> </CERIF>
