Download or read book Nutrition and Lactation in the Dairy Cow written by Philip C. Garnsworthy and published by Elsevier. This book was released on 2013-10-22 with total page 442 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nutrition and Lactation in the Dairy Cow is the proceedings of the 46th University of Nottingham Easter School in Agricultural Science. 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.

Download or read book Climate Smart Food written by Dave Reay and published by Springer. This book was released on 2019-01-01 with total page 201 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book asks just how climate-smart our food really is. It follows an average day's worth of food and drink to see where it comes from, how far it travels, and the carbon price we all pay for it. From our breakfast tea and toast, through breaktime chocolate bar, to take-away supper, Dave Reay explores the weather extremes the worlds farmers are already dealing with, and what new threats climate change will bring. Readers will encounter heat waves and hurricanes, wildfires and deadly toxins, as well as some truly climate-smart solutions. In every case there are responses that could cut emissions while boosting resilience and livelihoods. Ultimately we are all in this together, our decisions on what food we buy and how we consume it send life-changing ripples right through the global web that is our food supply. As we face a future of 10 billion mouths to feed in a rapidly changing climate, its time to get to know our farmers and herders, our vintners and fisherfolk, a whole lot better. Dave Reay is Professor of Carbon Management at the University of Edinburgh, UK. He has studied climate change for over 20 years, from warming impacts in the Southern Ocean, through carbon fluxes in forests, to greenhouse gas emissions from wetlands and agriculture. In 2018 he received the Chancellors Award for Teaching for his work in climate change education. His latest project involves managing a large area of coastal land in Scotland to regrow native tree species and trap a lifetimes carbon.

Download or read book Optimum Dairy Cow Replacement Policies to Maximize Income Over Feed Cost written by Richard Walker Rundell and published by . This book was released on 1967 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: Simulation of a dairy herd over a period of 15 years was used to examine replacement strategies among six operationally practical systems of culling cows which whould maximize income over feed costs. The strategies or criteria used to remove the lower ranking cows to a relatively constant herd size were: (1) Mature Equivalent (M.E.) milk production, (2) M.E. gross milk income, (3) actual milk production, (4) actual gross income, (5) income over feed cost, and (6) present value of expected gross income of cow and her subsequent replacements. Two each of prices of milk, fat differential, feed, and operational costs totaled 2 4 x 6 x 2 replications per trial or 192 replications. The following were treated as stochastic variables: (a) variation in milk production and milkfat percentage between cows and between lactations of the same cow, (b) chance of a calf being a heifer or bull, (c) chance of involuntary death or removal of cows and youngstock, and (d) chance of month of the year of involuntary removals. The mean and variance of the base herd approximated the average Michigan DHIA Holstein population in 1966. The sire value, approximating the best bulls used in A.I. was identical for any given year through all strategies and replications, but improved over time at the rate of 130 1b milk per year. Culls or cows removed because of low in each respective strategy were removed at the most profitable point to cull in their respective lactations by equating the milk income of the marginal month with the sun of the month's feed costs and monthly operational charges. Practical use of this simple method of determining when to cull cows within a lactation was demonstrated. A complete factorial design to analyze the generates data showed no significant differences between strategies under alternative combinations of prices in average income including salvage over feed cost per cow discounted to the present. This income was affected by the level of milk price (P
