Part II discusses the cow's nutrient interactions; responses to nutrients that yield protein and energy; and the influence of nutrient balance and milk yields. Part III tackles the efficiency of energy utilization in cows and its relation to milk production. Part IV talks about food intake of cows and the factors that affect it, while Part V deals with the different feeding systems for cows. The text is recommended for those involved in raising cows and dairy production, especially those who would like to know more and make studies about the relationship of nutrition and lactation of cows.
Download or read book Lactation in Farm Animals written by and published by BoD – Books on Demand. This book was released on 2020-01-22 with total page 144 pages. Available in PDF, EPUB and Kindle. Book excerpt: Greater knowledge of lactation allows us to alter environmental, nutritional, and milking procedures, or general management to maximize production. This book, focusing on lactation in farm animals (biology, physiological basis, nutritional requirements, and modelization), presents invited papers from internationally recognized scientists. This volume contains seven chapters covering the key topics related to milk production and lactation biology and physiology. The authors show that animals raised on a well-controlled nutrition regimen may have significant enhancement of succeeding lactations. Furthermore, the usefulness of a milk yield prediction system depends upon how accurately it can predict daily milking patterns and its ability to adjust to factors affecting supply. Milk yield prediction models have proven helpful for genetic analysis and for bio-economic modeling. On the whole, this book serves as an inspirational basis for both scientists and farmers.

Book Synopsis Precision Dairy Farming 2016 by : Claudia Kamphuis
Download or read book Precision Dairy Farming 2016 written by Claudia Kamphuis and published by BRILL. This book was released on 2023-09-04 with total page 459 pages. Available in PDF, EPUB and Kindle. Book excerpt: The supply of new innovative precision dairy farming technologies is steadily increasing. It aims to help farmers to be more labour efficient and to support them in their daily management decisions. At the same time, since many technologies are developed from an engineering perspective, adoption of these technologies is sometimes limited since knowledge on economic benefits and farmers' needs is often incomplete. This book covers the current status of precision dairy farming technologies and what farmers expect from them. It also includes insights and future perspectives on managing, analysing, and combining sensor information. Moreover, new innovative ideas that may better fit farmers' needs and expectation are introduced, ranging from technologies or innovations that aim at improved animal health and welfare, to those technologies that result in a more efficient use of feed and improved grazing management. This book is unique because science and engineering are combined to develop precision dairy farming technologies that are to be applied in practice. The book will serve as a stepping stone for new and innovative ideas within this rapidly growing area within dairy farming.
Book Synopsis Relationship Between Body Condition Score, Milk Yield, Reproduction, and Biochemical Parameters in Dairy Cows by : Wissal Souissi
Download or read book Relationship Between Body Condition Score, Milk Yield, Reproduction, and Biochemical Parameters in Dairy Cows written by Wissal Souissi and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Blood indicators are used as a tool to diagnose metabolic disorders. The present review aims to study the relationships between body condition score, milk yield, and reproduction and biochemical parameters in dairy cows. Live weight and body condition are indicators for dairy cow,Äôs health, milk productivity, and reproduction. Therefore, many authors investigated the effect of body condition score at calving and of change in body condition score on productive and reproductive performance, on lactation curve parameters, and on postpartum disease occurrence. Moreover, results showed that the cows calving at the highest body condition score lost more subcutaneous fat; condition score change did not exceed 1.05¬†units. Change in body condition score was positively associated with peak and total milk production. In addition, the decline in dairy reproductive performance may be due to a hampered process of metabolic adaptation. Adaptation to the negative energy balance is a gradual process. The use of risk factors is more appropriate and discussed. Among them are the body condition score and its derivatives, feed intake, the calculated negative energy balance, and metabolic parameters like the plasma concentration of insulin or the triacylglycerol content in the liver. Moreover, factors that play a role in the link between declined reproductive performance and the metabolic situation of the cow during lactating are discussed.

This edition includes: Recent research findings on the physiology of the oestrous cycle and its control; New techniques for monitoring and manipulating reproduction, including pregnancy diagnosis and embryo transfer; Advice on identifying common infertility problems and how to prevent and treat them. Reproduction Cattle 3e is essential reading for veterinary and agricultural students, as well as veterinarians and farmers involved in cattle reproduction.
Book Synopsis Body Condition Score and Dairy Form as Indicators of Dairy Cattle Disease and Reproductive Performance by :
Download or read book Body Condition Score and Dairy Form as Indicators of Dairy Cattle Disease and Reproductive Performance written by and published by . This book was released on 2003 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objectives of this research were to estimate heritabilities and correlations between body condition score (BCS) from various sources, determine the genetic relationship among BCS, dairy form, cow health and reproductive performance and investigate various models to analyze BCS and dairy form. BCS was obtained from herds using PCDART dairy management software and from linear type appraisals by Holstein classifiers. Cow health data was obtained from several herds recording disease treatments. Genetic evaluations for cow health in Denmark were also obtained. Reproductive data and yield data were provided by DRMS and AIPL-USDA. Heritabilities and correlations among traits were estimated with REML using animal and sire models. Random regression and repeatability sire models were compared. Fixed effects for all models included contemporary group effects, age, and days in milk (DIM) when available. Random effects were sire or animal and error. The heritability estimate of BCS from linear type appraisal was 0.22. The genetic correlation estimate between BCS from PCDART records and linear type appraisals was 0.87, between BCS and dairy form was -0.72 and between BCS and strength was 0.69. The genetic correlation estimates from random regression models between DIM 0 in lactation 1 and DIM 305 in lactation 3 were estimated to be 0.77 for BCS and 0.60 for dairy form. Higher BCS and lower dairy form were significantly correlated with lower milk yield, less metabolic disease and fewer days open. The relationship among BCS, dairy form, cow health and reproductive disease remained significant after adjustment for milk yield. The relationship between BCS and cow health and reproductive performance tended to be non-significant after adjustment for dairy form. Supplementing direct genetic evaluations for days open with evaluations for dairy form increased reliability of days open by an average of 0.06 for 19 recently proven bulls. Selection for lower dairy form or higher BCS will slow the deterioration of cow health and reproductive performance that accompanies selection for increased yield.
