Milk Urea Nitrogen Testing to Improve Protein Utilization in Dairy Cattle
Author:
Publisher:
ISBN:
Category :
Languages : en
Pages : 4
Book Description
A proper balance of protein & energy, or more specifically rumen degradable protein & rapidly fermentable carbohydrate, allows cows to make the best possible use of protein in the diet. This could mean higher production, lower feed costs, and less environmental impact from nitrogen in manure. Monitoring urea nitrogen concentration is an effective way to determine whether dietary protein & energy are in proper balance. This bulletin describes ways to test for urea concentrations, the effects of various dietary factors on milk urea nitrogen concentration, the variation in concentration by season & stage of lactation, the timing of urea sampling, and the frequency & cost of testing. It also includes a table showing the crude protein content of common feed ingredients and their rate of protein degradability.

Milk Urea Nitrogen of Dairy Cows
Author: M. A. Baset
Publisher: LAP Lambert Academic Publishing
ISBN: 9783659232718
Category :
Languages : en
Pages : 96
Book Description
Feeding practices followed by farmers in different feed bases and seasons were based on rice straw, small quantities of green grasses from various sources with small supplementation of concentrates. Milk urea nitrogen (MUN) concentration was higher under good base (38.86 mg/dl) than poor feed base condition (28.55 mg/dl). MUN of the local and crossbred cow was found 31.97 and 35.44 mg/dl, respectively. Milk protein was positively correlated with milk yield. MUN increased linearly from 16.79 to 22.46 mg/dl as dietary rumen degradable protein was increased from the lowest (-25%RDP) to the highest (+25%RDP) levels. Urea concentration was 16.97 % higher in +25%RDP and 12.55 % lower in -25%RDP compared to control diet (19.20 mg/dl). The dietary CP and rumen degradable protein had positive impact on milk yield, milk composition and milk urea nitrogen. It was found that feeding dietary rumen degradable protein up to a level of 789 g/d had a significantly positive impact on MUN level, but diets having required level of rumen degradable protein for feeding dairy cows in local condition need to be confirmed through further research.

Milk Proteins
Author: C.A. Barth
Publisher: Springer Science & Business Media
ISBN: 3642853730
Category : Science
Languages : en
Pages : 318
Book Description
This book reviews the state of knowledge and progress of research on food proteins, and in particular, milk proteins. Its basis is the Symposium on Milk Proteins that was held at the Federal Dairy Research Centre in Kiel, FRG, in June, 1988. Scien tists from around the world attended and addressed pure, as well as applied fields of protein research and technology. This book is divided into five sections, each adapted from the symposium's invited lectures, short communications, and poster presentations. New criteria for the "bio logical value" of dietary proteins and their relationships are considered according to: - Milk Proteins and Nitrogen Equilibrium - Milk Proteins and Ligands - Milk Proteins: Structural and Genetic Aspects - Milk Proteins: Technological and Functional Aspects - Milk Proteins and Clinical Nutrition Generally, different dietary proteins are classified according to their "biological value," i.e., their capacity to cause different retention of nitrogen in the body. But we think there are other intriguing leads worth studying that may help to identify which dietary proteins are best recommended for specific dietary situations or clini cal conditions. In addition, we have taken into consideration new fields such as attempts to determine the three-dimensional structure of proteins using two-dimensional NMR spectroscopy, and the application of genetic engineering to the lactating cell. In other words, we are on the way to the transgenic cow with customized milk constituents and composition.

Proteins and Non-protein Nitrogen in Human Milk
Author: Stephanie Atkinson
Publisher: CRC Press
ISBN: 9780849367953
Category : Medical
Languages : en
Pages : 268
Book Description
For the first time, an entire publication has been dedicated to providing a critical review of the identification and analysis of the milk specific proteins such as lactalbumin, lactoferrin and casein; the non-milk specific proteins such as plasma and membrane proteins; and the minor nitrogen-containing components such as enzymes, hormones, and growth factors. Biological roles, whether nutritional, endocrinological or immunological, of the specific nitrogen compounds in mammary milk production and/or growth and development of the breast-fed infant are also presented. Identification of the molecular weight compounds that have led to questions about their function in milk and their inclusion in modern infant formulas is thoroughly discussed and of great value to scientists in sub-specialties of biochemistry, nutrition, physiology and immunology, as well as to pediatric practitioners with primary interests in the infant food industry, academia, or clinical nutrition. The thoroughness of each chapter, often providing an historical panorama of the specific aspect of milk composition, makes this book useful for both the uninitiated and expert audiences who are interested in advancing their knowledge of human milk biochemistry and its physiological significance to the recipient infant.
