This book was released on 2001-02-09 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: This widely used reference has been updated and revamped to reflect the changing face of the dairy industry. New features allow users to pinpoint nutrient requirements more accurately for individual animals. The committee also provides guidance on how nutrient analysis of feed ingredients, insights into nutrient utilization by the animal, and formulation of diets to reduce environmental impacts can be applied to productive management decisions. The book includes a user-friendly computer program on a compact disk, accompanied by extensive context-sensitive "Help" options, to simulate the dynamic state of animals. The committee addresses important issues unique to dairy science-the dry or transition cow, udder edema, milk fever, low-fat milk, calf dehydration, and more. The also volume covers dry matter intake, including how to predict feed intake. It addresses the management of lactating dairy cows, utilization of fat in calf and lactation diets, and calf and heifer replacement nutrition. In addition, the many useful tables include updated nutrient composition for commonly used feedstuffs.

Tye and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this experiment was to determine if nutrient utilization and energy partitioning by lactating dairy cows would differ in response to dietary corn grain (CG) types [steam-flaked corn (SFC) vs. high-moisture corn (HMC)] and to test if the types of CG would interact with slow-release urea (SRU) on lactational performance and energy utilization. Eight multiparous Holstein cows (32 ℗ł 8.2 days-in-milk) were used in a duplicated 4 ©7 4 Latin square with one square consisting of ruminally cannulated cows. A 2 ©7 2 factorial arrangement was used to test 4 dietary treatments: SFC without SRU, SFC with SRU, HMC without SRU, and HMC with SRU. The experimental diets contained 60.5% dry matter (DM) of forages, whereas 12.9% or 14.4% DM of SFC or HMC was added in the diets, respectively. The SRU was supplemented at 0.46% DM, replacing a mixture of soybean meal and canola meal in a 50:50 ratio. Feeding HMC decreased intakes of DM, crude protein, and fiber compared with SFC. Supplementation of SRU did not affect intakes of DM and nutrients, whereas it tended to increase intakes of DM or increased crude protein intake under SFC but no effect under HMC, leading to CG ©7SRU interactions on DM and crude protein intakes. Neither type of CG nor SRU supplementation affected milk production except that cows fed HMC-based diets tended to decrease energy-corrected milk yield compared to those fed SFC-based diets. Utilization of HMC in the diet had a tendency to increase dairy efficiency based on milk yield over SFC utilization. Cows fed HMC diets gained more body weight (BW) than those fed SFC diets, whereas supplementing SRU tended to reduce BW gain regardless of type of CG. Cows fed HMC diets shifted more net energy into BW compared with those fed SFC diets, whereas supplementing SRU tended to decrease a portion of net energy partitioned into BW gain under both SFC and HMC diets. Dietary treatments exerted minor impacts on ruminal fermentation profiles. Feeding HMC diets decreased fecal N excretion compared with SFC diets. In addition, supplementing SRU increased fecal N excretion under SFC, but it was decreased by SRU with HMC, leading to an interaction between CG and SRU. These collective results demonstrate that feeding HMC with SRU can be a practical option in high-forage lactation diets to maintain or improve nutrient and energy utilization efficiency and minimize negative environmental impacts.

This book was released on 2014 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: A meta-analysis, two animal experiments, and one data mining experiment were conducted to determine the effects of feeding reduced-starch (RS) diets and starch digestibility on dairy cattle performance. A meta-analysis was conducted to determine the effects of feeding RS diets on intake, lactation performance, and ruminal parameters. Dietary starch was reduced by partial replacement of grain with non-forage fiber sources or forages. Dry matter intake, milk, fat, and protein yield were decreased as dietary starch was reduced. Total ruminal volatile fatty acid concentration was decreased as dietary starch was reduced. Molar proportion of ruminal acetate was increased as dietary starch was reduced. Reducing dietary starch decreased lactation performance of dairy cows. The first animal experiment determined the effects of normal or RS diets and finely- or coarsely-ground corn on performance of lactating dairy cows. Milk and protein yields were reduced for cows fed RS diets, however, fat-corrected milk was increased for cows fed the normal-starch finely-ground corn and RS coarsely-ground corn diets. Ruminal digestibility of NDF was increased for cows fed the RS diets. Total tract digestibility of NDF was greater on the RS diets, while total tract starch digestibility was greater on the RS diets and the finely-ground corn diets. Cows fed the finely ground corn diets had greater ruminal propionate and lower rumen pH. The second animal experiment determined the effects of feeding RS diets by partially replacing corn grain with soyhulls (SH) or corn silage (CS), or CS and grain with SH. Partial replacement of corn grain with SH or CS increased milk fat content compared with partial replacement of CS and corn grain with SH. Partial replacement of corn grain with SH or CS increased total tract NDF and starch digestion. Diet digestibility and performance of mid-lactation cows fed RS diets by partially replacing corn grain with SH or CS was similar to or improved compared to cows fed a normal-starch diet. The third experiment tested whether total tract starch digestibility can be predicted from the concentration of starch in fecal dry matter. Total tract starch digestibility was predicted accurately from fecal starch concentration.

Download or read book Effects of Diet Particle Size and Supplemental Hay on Mitigating Subacute Ruminal Acidosis in High producing Dairy Cattle written by Alanna Kmicikewycz and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Achieving maximum milk production in dairy cows increases the risk of subacute ruminal acidosis (SARA), a severe digestive disorder that is an economic concern for producers. High-producing dairy cattle require more dietary energy in order to meet the demands of increased milk production. High energy diets, however, are low in physically effective NDF (peNDF) and high in starch. Starch sources in the diet are often processed in a manner to optimize starch availability in the rumen and the fiber sources are often highly digestible and short in particle length. As a result, these types of diets are highly fermentable in the rumen and often lack the structural characteristics needed to maximize rumination time and the flow of salivary buffers into the rumen. The result is reduced pH in the rumen and increased risk of acidosis. While it is critical to meet the energy requirements of high-producing cows, acidosis must be avoided to ensure high milk production and efficient use of feed. There is growing evidence that dairy cows will select feeds with high ruminal buffering capacity in an attempt to attenuate the effects of low ruminal pH. Four experiments were carried out on early to mid-lactation Holstein dairy cows to investigate the effects of corn silage particle size and supplemental hay on feed preference, ruminal fermentation, dry matter intake, and milk yield and components during an induction of SARA. Together, these experiments provide valuable observations in regards to feeding supplemental hay as a nutritional management strategy to mitigate SARA. Feeding supplemental long hay to high-producing dairy cattle experiencing SARA was found to be beneficial and helped maintain dry matter intake, alleviate low ruminal pH, and blunted the shift of FA towards trans-10, C18:1. In addition, when fed with short cut corn silage, providing long supplemental hay helped accelerate recovery from SARA.
