The effects of different milking intervals and milking times per day in jennet milk production.
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...
متن کاملEvaluation of an experimental milking pulsation system for effects on milking and udder health.
This study was to test whether cows milked by an experimental pulsation method differed from cows milked with conventional pulsation milking in somatic cell count (SCC), intramammary infections (IMI) defined by milk bacteriological culture results, teat end condition, or milk flow rate. The study design was a 1-yr trial with a completely randomized block crossover. Holstein cows were blocked in...
متن کاملEffects of Milking Frequency on Milk Production and Composition of Holstein Cows during Their First Three Lactations
The objective of this study was to investigate the effect of milking frequency (two times daily vs. three times daily) on the 305-d lactation milk, fat and protein yield and fat and protein percentage of Holstein dairy cows in Morocco. Data analyzed were 31400 records collected between 2009 and 2016 on 14272 cows raised in 194 herds. The frequency of milking had significant effects (P<...
متن کاملEffects of increased milking frequency during early lactation on milk yield and udder health of primiparous Holstein heifers.
In dairy cows, increased milking frequency (IMF) during early lactation stimulates an increase in milk yield that partially persists through the remainder of lactation. However, the effects of IMF on lactation performance and udder health of primiparous heifers have not been clearly established. The objective of this study was to determine the effects of IMF during early lactation on milk yield...
متن کاملMilking: How Much Milk Can Remain in the Udder?
Opinions are divided about the degree to which an udder should be empty after milking. While many farmers, based on their experience, try to empty the udder as completely as possible, their colleagues as well as some representatives of the milking industry and some milking consultants have a more relaxed attitude. They argue that it is completely normal that milk remains in the udder after milk...
