Book excerpt: The objectives of this research were to: 1) express variation in DHIA herd performance measures by means of a limited number of factors; 2) determine the relationship of DHIA performance measures to profit score and their sensitivity to market price changes; and 3) identify which herd performance measures changes were associated with profit score changes over a five-year horizon. For the variability in DHIA herd performance measures, large variation among herds would indicate notable opportunity for changing management strategy. It was concluded that three independent factors offer the greatest opportunity for improvement within most production subsets. Notably, the reproductive measures of calving interval, days open, and percent cows bred> 3 times accounted for a large portion of variability among herds. Also, considerable variation among herds for percent cows with SCS 4-5 and cows with SCS> 5 suggests that management practices or their successful implementation at preventing mastitis differ greatly from farm to farm. Simple regression was used for determining the relationship of DHIA performance measures to profit score and the sensitivity of performance measures to market price changes. It was determined that 1) several measures were related to profit score by quadratic effects; 2) for measures with quadratic relationship to profit score, resulting changes in score for herds are dependent on the current herd performance for the respective measure, and 3) milk yield was not the only measure that significantly impacted profit score. Sensitivity analysis indicated that several of the performance measures were sensitive to milk price changes. These price sensitivities suggest that producers need to consider economic conditions when assessing the importance of different management changes. Lastly, herds which differed in realized changes for profit score over a five-year horizon were identified, characterized for performance measures, and performance changes that were associated with profit score changes were determined. Changes in milk yield were not associated with changes in profit score for herds that either significantly or consistently increase profit over time. Rather, it was shown that average annual changes in reproductive measures had a more important effect on changes in profit score for herds that were less profitable.
Book Synopsis The Dairy Herd Improvement Association Program by : James Frank Kendrick
Download or read book The Dairy Herd Improvement Association Program written by James Frank Kendrick and published by . This book was released on 1953 with total page 24 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Nearly 50 years ago a few progressive dairy farmers in Michigan organized the first cow-testing association in the United States. They wanted to improve the profitableness of their herds. They hired a tester to weigh and test the milk of each cow and keep a record of her food cost and income. They wanted that information so the could cull the low producers from their herds and feed the rest more economically. In the first 4 years of their pioneer effort these Michigan dairy farmers doubled the average profit per sow. since then thousands of other dairy farmers have followed their example with equally striking results. The cow-testing movement grew and eventually expanded into the present-day dairy-herd-improvement-association program. Members of these associations now use their records not only to test the cows but to prove the bulls. The improvement they have brought about in their herds is one of the outstanding 'success' stories in agriculture. No herd is so good that it cannot be made better by effective culling, good feeding, and the use of production-tested breeding stock. Breeding records and records of production, feed cost, and income are essential for carrying on such an improvement program. Membership in a dairy-herd improvement association is one of the best and most economical ways for any dairy farmer to obtain the necessary records."--Page ii.

Said symposium was concerned with the significant advances in the field of nutrition and lactation in the dairy cow. The book is divided in five parts. Part I deals with the principles behind nutrition and lactation of cows. 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.

Book Synopsis Breeding for robustness in cattle by : Marija Klopcic
Download or read book Breeding for robustness in cattle written by Marija Klopcic and published by BRILL. This book was released on 2023-09-04 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: The past decade has revealed unfavourable trends in e.g. fertility, udder health and locomotion in some major dairy cattle breeds due to a large increase in production and insufficient consideration of functional traits in the breeding goals. Such unfavourable trends in some functional traits increase costs. Additionally, the enlargement of herds leads to less available labour time per individual cow. This asks for cows that are easy to handle. At the same time, society is demanding a higher welfare standard of animals. These contradicting developments have increased the desire for so called more robust animals. Robustness can be defined as 'the ability to maintain homeostasis in commonly accepted and sustainable herds of the near future'; or 'the ability of the cow to function well in the environment she lives in as well as in a wide range of climates and production systems'. This book contains a series of articles (26) dealing with the concept of robustness, including aspects like evolution, genetics, environment, animal health and welfare, and integrity. Besides the major functional traits also the links to energy balance, hot climatic conditions, and the attitude and input of stakeholders towards robustness as part of the breeding program are discussed. This book is the first attempt to summarise the available knowledge concerning this topic in cattle, making this book unique. The contributions are from authors of 16 countries from all over the world. However, the focus is presently on farm animal level, while in future robustness of the whole production system may also require additional attention.

Download or read book Cow Talk written by Rebecca Doyle and published by CSIRO PUBLISHING. This book was released on 2015-02-03 with total page 256 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this manual is to improve the welfare of dairy cattle in tropical developing countries, and by doing so, optimise cow and herd performance. It gives the stockmen and farmers directly concerned with the cattle a better understanding of animal behaviour and the ways cattle communicate their comfort or distress. The book discusses normal cattle behaviour and shows how domestication and breeding can affect behaviour to achieve high levels of production of milk, live weight gain and fertility. Animal welfare is important for producers because it can affect the health, production and contentment of cows. Animal welfare practices which adversely affect cow and herd performance on tropical small holder dairy farms are identified. Advice is then given to change the animal's environment or modify a handler's technique to ensure cattle have the degree of comfort needed to achieve more profitable and sustainable systems of livestock farming. Cow Talk will be a beneficial resource for farmers who want to improve animal welfare, farm advisers who can assist farmers to improve their welfare practices, educators who develop training programs for farmers and dairy advisers, and other stakeholders in tropical dairy production such as local agribusiness, policy makers and research scientists.
