This study was carried out to determine the association between some milking factors and milk quality in dairy cows. While questionnaires collected from a total of 50 smallholder farms in Bafra and Samsun, number of milkers (NM), milking duration (MD), care frequency for milking machine (CMM) and age of milking machine (AMM) were used as milking parameters. Milk quality was measured by somatic ...

Few studies have been developed to evaluate the differences of bovine mastitis situation between hand and machine milking under the American tropic conditions. Twenty dairy herds were studied, 11 using hand milking (HM) and 9 machine milking (MM), from «San José de las Lajas» municipality, Mayabeque province. Between May 2009 and March 2012, samples from 182 cows (113 MM and 69 HM) were obtaine...

Grazing dairy cows milked by an automatic system (AS) experienced mild heat stress (HS) periods twice during the summer. The daily temperature humidity index (THI) during these periods were higher than 72. Milk production, as well as milking frequency, rumination time and milk fat to protein ratio (F/P) during these periods were compared with adjacent periods with mean THI of 61. The daily milk...

In their first 150 days of lactation, nine Ragusana jennets were investigated at the 'Istituto Sperimentale Zootecnico per la Sicilia' (ISZS) in Palermo, to study the effects of different milking typologies on milk production. The jennets were kept in a paddock and were fed hay ad libitum and concentrate (3.5 kg jennet/day). From post-foaling day 21, every 3 weeks individual milk amounts were r...

the objective of this study was to evaluate the effect of different milking frequencies in the first 6 weeks of lactation on milk production and milk constituents, blood metabolic profiles and reproductive performance of fresh dairy cows. the milking frequencies imposed were three times daily milking for 42 days (3x), six times daily milking for the first 21 days of lactation and three times da...

al implications for stakeholders: Automatic milking systems (AMS)s can be operated successfully within a grass based milk production system and milk yields comparable to many commercial batch milking systems can be achieved when grazing management is managed in order to control cow traffic The fact that milk yield/cow/day was not significantly affected by reducing milking frequency from 1.8 to ...

The aim of this study was to investigate the effect of milking frequency (three times daily vs. two times daily) on the lactation curve shape, partial and 305-d lactation performance in Holstein dairy cows in Iran. Data from February 2000 to December 2012 comprising 217345 lactations on 141364 cows distributed in 324 herds collected by the Animal Breeding Center of Iran were used. The mean milk...
