BACKGROUND: Methionine has been suggested as the firstlimitingamino acid for milk production in ruminants. It is importanthow to increase milk protein yield and milk fat in dairy ruminants.OBJECTIVES: This study was set to investigate the effect of rumenprotected methionine (RPMet) on milk composition of lactatingCashmere Rayeni goats. METHODS: 40 healthy singletonCashmere Rayeni goats about 3 ...

The results herein presented furnish exact critical evidence for one more stage in milk secretion. Cows producing up to 30 pounds of milk at one milking are shown to have the lactose equivalent of all this milk in the udder when milking commences. The average excess of lactose found in the udder after subtracting the amount necessary for the contained milk is equal to 2.1 pounds. This represent...

The content of vitamin C, vitamin B2 and fat-soluble vitamins E and A in camel milk was studied. The milk samples were collected from 20 individual camels (Camelus dromedarius) in two different occasions. The study showed that camel milk contains considerably less vitamin A and B2 than cow milk while the content of vitamin E was about the same level. The level of vitamin C was in average three ...

  Background : Since milk is considered as one of the most common foods in human life, this research aimed to evaluate the quality of milk produced in traditional and industrial dairy farms of Yazd province in 2007.   Materials and Methods : In this descriptive study, six farms were selected in the cities Sadoogh, Yazd and Mehriz and sampling was performed in each of them bimonthly...

The effect of foodstuffs on the natural transformation of Bacillus subtilis was investigated. As examples of complex food matrices milk with various fat contents as well as chocolate milk were used. The frequencies of transformation varied with the fat content and ranged between 3.8 X 10(-4) and 1.4 X 10(-3). Highest frequencies of about 3 X 10(-3) were observed in chocolate milk with 1.5% fat....

A simple micromethod has been devised for estimating the fat and energy content of human milk based on the centrifugation of milk in a haematocrit centrifuge. The percentage of cream, or "creamatocrit," is read from the haematocrit capillary tube and is linearly related to the fat and energy content. The technique, which is rapid and cheap, may be used in clinical practice, in research, and in ...

The cholesterol content in cow milk is influenced by both genetic and environmental factors. Despite the fact that the main part of cholesterol contained in milk is synthesised endogenously, via process independent of the offered diet type, the chemical composition of feed (especially fat) affects the content of this sterol in cow milk (Precht, 2001). The content of cholesterol in cow milk is r...
