Liners and Teat End Health
In the dairy industry world wide, several hundred types of liners are used to milk dairy cows. The enormous amount of liner types with different characteristics in size, form, consistency and other design and manufacturing characteristics indicate that no ‘best’ liner has been identified in the last 60 or so years since machine milking has become the common method for milk harvesting. Mechanica...
متن کاملEffect of machine milking on bovine teat sinus injury and teat canal keratin
Introduction In Ireland, cows are generally milked with milking machines with 3.2kg clusters, with wide-bore tapered liners (31.6mm – 20.6mm) and 4x0 pulsation (WB). Outside of Ireland, most milking machines have 1.65kg clusters, narrow-bore liners (25.0mm – 20.0mm) and 2x2 pulsation (NB). O’Callaghan (2001) showed that the mouthpiece cavity vacuum was higher with wide-bore tapered liners than ...
متن کاملTeat Condition - Prevention and Cure through Teat Dips
Teat end and skin condition is an important property that is affected by a variety of factors including the milking machine, weather, bedding, and physiological status. Teat disinfection is employed primarily to aid in the prevention of new infections but is also an opportunity to improve teat condition. Teat condition or teat tolerance studies are a required part of medicinal product registrat...
متن کاملComparative evaluation of SIMPL silicone implants and NIT natural teat inserts to keep the teat canal patent after surgery.
The objective of this study was the comparative evaluation of SIMPL silicone implants and NIT natural teat inserts to keep the teat canal patent after teat surgery. The study was performed on 100 teats of 97 cows treated surgically for milk flow disorders. After surgery, 53 teats were administered with SIMPL and 47 with NIT, and rested for several days. Before treatment and 1 and 6 mo later qua...
متن کاملOvermilking and Teat Condition
Overmilking is a matter of concern because it may affect teat condition and udder health. The historic background for overmilking is mainly based on the assumption that all milk should be removed from the udder in order to maximise the milk yield. However, breeding for high milk yields has provided cows with a high alveolar capacity, large cistern capacity, and a higher proportion of cisternal ...
