Book Description
Objectives of the study were to evaluate if calves fed 6 L of high protein milk replacer (HPMR; 1135 g/d, 28% crude protein (CP), 20% fat) had improved performance and health as compared to calves fed 4 L of a conventional milk replacer (CMR; 454 g/d, 20% CP, 20% fat) in heat stress and non heat stress environments. Holstein bull calves (n=52) 3 d of age were assigned to a 2 x 2 factorial trial based on initial BW, physical health score, and total serum protein levels. One half of each nutrition group was housed indoors with temperature control, non-heat stress (NHS) environment and one half was housed outside under a shaded barn in subjecting them to a heat stress (HS) environment. The study was conducted for 56 d from June 18 to August 13, 2010. Average thermal heat index (THI) was calculated for each day using the average of 24 recorded temperatures and relative humidity (RH%). The 56 d average, low, and high range THI for the HS was 79, 67, and 86, respectively, while THI for the NH was 69, 66, and 74, respectively. Weekly measurements of body weight (BW) in kg, body length (BL), hip width (HW), wither height (WH), heart girth (HG), and hip height (HH) in cm were collected and average daily gain (ADG) was calculated. Water consumption (WC) in mL and starter intake (SI) in grams was measured daily. Feed conversion (FC) was also calculated for each nutritional treatment and environment. Fecal scores (FS) of 1 to 4 (1=hard, firm, 2=soft, firm, 3=no form, and 4=watery) were recorded daily. Calves with a FS of3 were considered to have diarrhea and required treatment. Respiration rates (RR) were recorded at 0630 (AM) and 1830 (PM) to monitor respiratory challenges while rectal temperatures (RT) were also measured using a digital thermometer daily in AM and PM to monitor febrile events. If RT was greater than 39.2 degrees C for NHS calves and 39.7 degrees C for HS calves, they were treated for febrile events (FE). Data was analyzed using PROC MIXED (SAS 9.2). HPMR had a greater (P & lt; 0.01) WH, HG, BL, HH, ADG, WC, and FS than the CMR (0.15 vs. 0.11, 0.37 vs. 0.28, 0.27 vs. 0.22, 0.21 vs. 0.14, 0.82 vs. 0.58, 4235 vs. 2656, and 2.05 vs. 1.73, respectively). HS had a greater (P & lt; 0.01) WC than NHS (4365 vs. 2526, respectively). CMR had a greater SI and FC (P & lt; 0.05) than HPMR (0.942 vs. 0.437, and 1.99 vs. 1.78, respectively). HS had a higher RT AM, RT PM, RR AM, and RR PM (P & lt;0.01) than NHS (38.87 vs. 38.77, 39.03 vs. 38.79, 35.79 vs. 32.77, and 55.73 vs. 38.57, respectively. Calves in NHS had a higher FE (P & lt;0.01) than the HS calves (6.24 vs. 2.33). There was no significant difference in growth parameters in HS or NHS in calves of like feeding strategies. The results show calves in HS experienced higher RT AM, RT PM, RR AM, and RR PM. The increased protein and energy fed to the HPMR calves resulted in greater FS and increased growth.

Book Description
Dr. Anjali Aggarwal is working as a Senior Scientist at National Dairy Research Institute, Karnal (India). She holds a PhD degree in Animal Physiology and is involved in research and teaching at post-graduate level. Her area of research work is stress and environmental physiology. She has more than 50 publications, two technical bulletins, four manuals and many book chapters to her credit. She has successfully guided many post-graduate and PhD students. Her major research accomplishments are on microclimatic modification for alleviation of heat and cold stress, mist and fan cooling systems for cows and buffaloes, and use of wallowing tank in buffaloes. Her work involves the use of technology of supplementing micronutrients during dry period and early lactation to crossbred and indigenous cows for alleviating metabolic and oxidative stress and improved health and productivity. Studies are also done in her lab on partitioning of heat loss from skin and pulmonary system of cattle and buffaloes as a result of exercise or exposure to heat stress. Dr. R.C. Upadhyay is working as Head, Dairy Cattle Physiology Division at National Dairy Research Institute, Karnal (India). He graduated in Veterinary Sciences and obtained his PhD degree in Animal Physiology. His area of recent research is climate change, stress, and environmental physiology. His major research accomplishment is on climate change impact assessment of milk production and growth in livestock. His work also involves studying methane conversion and emission factors for Indian livestock and use of IPCC methodology of methane inventory of Indian livestock. Heat shock protein-70 expression studies in cattle and buffaloes are also done in his lab. Draught animal power evaluation, fatigue assessment, work-rest cycle and work limiting factors form the highlights of his work. Studies on partitioning of heat loss from skin and pulmonary system of cattle and buffaloes and electrocardiographic studies in cattle, buffalo, sheep and goat are also undertaken in his lab. He has more than 75 research papers, four books and several book chapters to his credit. Technologies developed and research done by him include methodology of methane measurement: open and closed circuit for cattle and buffaloes; inventory of methane emission from livestock using IPCC methodology; livestock stress index: thermal stress measurement based on physiological functions; and draught power evaluation system and large animal treadmill system. He received training in Radio-nuclides in medicine at Australian School of Nuclear Technology, Lucas heights, NSW, Australia in 1985 and Use of radioisotopes in cardiovascular investigations at CSIRO, Prospect, NSW, Australia, during 1985-86. He has guided several post-graduate and PhD students. He is recipient of Hari Om Ashram Award-1990 (ICAR) for outstanding research in animal sciences.

Book Description
The Voluntary Food Intake of Farm Animals offers a wide discussion on food intake among farm animals. The book presents various studies, facts, details, and theories that are relevant to the subject. The first chapter begins by explaining the basic definition and significance of voluntary food intake. This topic is followed by discussions on meal patterns, the main features of eating, and the similarities between species. The next chapter explores theories about the food intake control, which are divided into two types: single-factor theories and multiple-factor theories. In Chapter 3, the discussion is on the food's pathway, including elaborations on the various receptors. Chapter 4 considers the central nervous system's involvement in the voluntary food intake and the energy balance regulation. The next couple of chapters highlight the possible reasons that affect food intake; among them are pregnancy, fattening, physical growths, and the environment. In the book's remaining chapters, the discussion revolves around grass intake and the prediction and manipulation of voluntary food intake. The book serves as a valuable reference for undergraduates and postgraduates of biology and its related fields.

Book Description
In order to meet increasing global demand for meat and animal by-products increasingly intensive animal production is necessary. Creating a sustainable system in animal agriculture that works in different production environments is a major challenge for animal scientists. This book draws together themes on sustainability that have emerged as the most pressing in recent years. Addressing practical topics such as air quality, manure management, animal feeds, production efficiency, environmental sustainability, biotechnology issues, animal welfare concerns, societal impacts and an analysis of the data used to assess the economic sustainability of farms.
