The study was aimed at identifying the pathogens causing subclinical udder infections in representative Israeli dairy goat herds and determining their effect on milk quality. Five hundred goats in ten flocks of various breeds and crossbreeds were surveyed. Of the 500 goats, 13.4% were in their first lactation, 36.4% were in their second lactation and 50.2% were in their third or higher lactatio...

In this study, a new quarter individual milking system called Multilactor® (MULTI) was compared with a conventional milking system (CON). The target of the developments in the field of milking technique is to obtain the whole milk from the teat of the animal in the shortest possible time without causing any detrimental effect on udder health. The most direct measure of the milking system effect...

A total of 90 cows from three commercial farms were used to evaluate the relationship between subclinical mastitis and clinical mastitis and thermal nociceptive threshold. Milk strips from all udder quarters were tested for clinical mastitis with visual inspection of milk and udder alterations and for subclinical mastitis using California Mastitis Test. Milk yield was recorded, milk was sampled...

Our knowledge of the mammary gland as related to its size and function has been largely based on the observational relationship which exists between udder size and the milk the cow is able to give.1 Briefly considered the data available consist of two measurements, the milk production of the cow in pounds and the relative degree of perfection of the udder in size, shape, and quality as measured...

The primary objective of premilking udder preparation and teats antiseptic is to achieve an acceptable level of decontamination of teat skin. This aids in reducing the spread of microorganisms and incidence of new intramammary infections, and in minimising the number of bacteria. The aim of our studies was to investigate the influence of pre-milking teat antiseptic solutions on total bacterial ...

The current study was planned to investigate the potential risk factors and their association with mastitis in Cholistani cattle. For this purpose milk samples were collected and examined for mastitis using California Mastitis Test. The results showed an overall 21.96% prevalence of subclinical mastitis. The analysis of variance did not show significant association of tail size, live body weigh...

This article examines the relationship between shape, size and of udder Bushuev cows on different categories farms their milk yield. It was determined that yield belonging to form bowl-shaped in all higher from 720.9 kg 641.8 than peers round udder. In comparison, with a cup-shaped 3.3 cm 2.2 wider, length 9.1 7.8 longer, circumference 6.3 8.7 bigger, depth 1.6 2.7 nipple diameter 0.06 0.35 cm,...

Mastitis is a significant disease of adult dairy cattle affecting up to 40 percent of cows within a herd at any given time. Recent surveys show that udder health problems are consistently the most frequent cause of morbidity with the US dairy cattle population (Table 1). The U.S. dairy industry loses an estimated $2 billion every year due to mastitis, with reduced milk production accounting for...

Analysis was made of the relationship between conformation traits and lifetime production efficiency of the cows that first calved in 2000 and represented the active population in the Pomorze and Kujawy regions of Poland. The CORR Pearson procedures of SAS package were used in the statistical calculations. It was found that there is a statistically significant relationship, weak or low on the G...
