The main purpose of this article is to describe interaction between physiology of lactation and milking machine. This is important in order to avoid bad influ­ ences (such as: high somatic cell count (SCC), mastitis, etc.). The paper is divided into two parts: The anatomy part describes udder characteristics needed for healthy udder and high milk yield. The milking machine part describes milkin...

INTRODUCTION Mastitis can occur at any stage of a cow’s productive life. Microbiological investigations of clinical bovine mastitis reveal a causative agent in 75–95% of cases. There is good evidence that microorganisms are involved in almost all cases. At least 137 infectious causes of bovine mastitis are known, but the majority of cases are caused by only a few common bacterial pathogens, nam...

The objective was to examine the direct and correlated responses of linear type, yield traits, and somatic cell scores (SCS) to divergent selection for predicted transmitting ability for type (PTAT) in Holsteins, while maintaining selection for yield traits across lines. For four generations, one-half of the University of Nebraska research Holstein herd was bred to Holstein sires with PTAT > 1....

BACKGROUND Radiation-induced skin reaction (RISR) is one of the most common and distressing side effects of radiotherapy in patients with cancer. It is featured with swelling, redness, itching, pain, breaks in skin, discomfort, and a burning sensation. There is a lack of convincing evidence supporting any single practice in the prevention or management of RISR. METHODS/DESIGNS This double-bli...

Recent studies show that immunoglobulins A, G, and M contribute significantly to the maintenance of udder health. Unfortunately, the concentration of immunoglobulins in cow milk during the middle period of lactation is low therefore the question of how to stimulate and maintain a sufficient level and spectrum of antibodies in the udder is topical. The aim of the present study was to evaluate th...

Received: Revised: Accepted: Online available: September 02, 2015 October 14, 2015 October 25, 2015 January 13, 2016 The purpose of the present study was to describe the normal ultrasonographic characteristics of the udder and teats in lactating Jennies. Seven lactating Baladi Egyptian Jennies were examined ultrasonographically using 6-8 MHz linear probe. Sagittal and transverse scans of the ud...

This study determined association of some morphometric characteristics of udder with mastitis in dairy cattle. For this purpose; 100 animals each negative and positive for mastitis by California Mastitis Test and bacteriology, were selected from amongst those brought for slaughter at Faisalabad abattoir. Morphometric observations on udder were recorded pre-slaughter; whereas, samples from mamma...

1. [U-14C]glucose was infused intravenously into conscious lactating goats exposed to thermoneutral or cold environments for a total of 24 h. The irreversible loss of glucose from the whole body and uptake of glucose by the mammary gland was measured and glucose utilization in the udder was studied by measuring the incorporation of radioactivity into carbon dioxide in mammary venous blood, into...

The objective of this study was to determine the effect of tail docking on somatic cell count (SCC), intramammary infection (IMI), and udder and leg cleanliness in commercial dairy herds. Lactating dairy cows (n = 1250) from eight Wisconsin farms were blocked by farm and randomly allocated to tail docked (D) or control (C) groups. Milk samples, somatic cell counts, and hygiene scores were colle...
