A Tool Box for Assessing Cow, Udder and Teat Hygiene

Infection of the mammary gland with environmental bacterial pathogens is the most significant udder health problem facing the dairy industry in North America. Forty years ago, Neave et al. (1966) stated that the rate of new intra-mammary infection is related to the number of bacteria that the teat end is exposed to, and several studies have made associations between clean housing, clean cows an...

Effect 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 ...

W-MP-4: Teat End Condition Scoring (Neijenhuis System)

The health and integrity of teats and streak canals is positively correlated to udder health and the incidence of mastitis. One sign of a reduction in teat end integrity is formation of excessive callus known as hyperkeratosis. Seiber and Farnsworth were the first to identify teat end hyperkeratosis and establish a teat end scoring system. Scoring systems have been developed to help standardize...

Accuracy-Based Scoring for Phrase-Based Statistical Machine Translation

Although the scoring features of state-of-theart Phrase-Based Statistical Machine Translation (PB-SMT) models are weighted so as to optimise an objective function measuring translation quality, the estimation of the features themselves does not have any relation to such quality metrics. In this paper, we introduce a translation quality-based feature to PBSMT in a bid to improve the translation ...
