This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein nutrition of dairy cattle is important to support the productive performance of high producing lactating dairy cows. Canola meal (CM) and dried distillers’ grains (DDGS) have been the primary protein meals fed on California dairies for over 10 years but decreases in the relative price of soybean meal (SBM) have created interest in how best to include it in lactation rations containing CM and DDGS. Three pens of high producing multiparous Holstein cows were fed diets supplying 0, 35 or 70 g/kg SBM on a dry matter (DM) basis which replaced CM in a manner which held the proximate nutrient content of the diets constant. Diets were rotated through the pens in a Latin square design such that each pen of cows experienced each diet once. Milk and component yields were lowest at the highest level of SBM (P

This book was released on 2020 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Objective: Evaluate the impact of substituting canola meal (CM) with solvent extracted distillers grain with solubles (NovaMeal; NM, Brookings, SD) and urea as protein sources on milk parameters and economics in a commercial dairy herd. Materials and Methods: A total of 2,817 Holstein cows averaging 91 ± 49 DIM were enrolled to one of four dietary treatment groups: 1) primiparous control (C) with 3.1 kg CM, 0.058 kg urea; 2) primiparous treatment (NT) substituted CM with 2.1 kg NM, 0.10 kg urea; 3) multiparous C with 3.5 kg CM, 0.057 kg urea; and 4) multiparous NT substituted CM with 2.4 kg NM, 0.11 kg urea. Results and Discussion: Primiparous NT cattle that were on treatment for the entire length of the trial period (ETP) were lower in milk yield, ECM, milk fat yield, and milk protein yield and %. Multiparous NT ETP cows were lower in milk yield, milk protein yield and %, and higher for 3.5 % FCM, and milk fat yield and %. The C TMR were more expensive vs. NT, however, due to C being greater in average milk per cow/d, C was still more profitable vs. NT. Implications and Applications: Supplemented urea and NM, partially substituting CM as a protein source in a lactating dairy cattle TMR, had a positive impact on milk fat response, but was not as profitable with the assumptions of the economic model.

Download or read book Using Indirect Calorimetry to Investigate Feeding Value of Byproducts for Lactating Dairy Cattle written by Mickayla Ann Marie Myers and published by . This book was released on 2018 with total page 152 pages. Available in PDF, EPUB and Kindle. Book excerpt: Byproducts have played a major role in dairy nutrition by providing a cheaper protein and fiber source, while also utilizing a product that would otherwise be waste from the human perspective. Use of byproducts in the dairy industry should allow for continued and overall increases in production and efficiency of the dairy industry. Two of the more popular byproducts in the dairy industry today are dried distillers grains and solubles and canola meal. In the first experiment, 12 multiparous lactating Jersey cows were used evaluate the feeding value of dried distillers grains and solubles (DDGS) or canola meal. A replicated 4 × 4 Latin square design was used to compare four different dietary treatments. Treatments were composed of a control (CON) containing no byproducts, a treatment diet containing 10% (DM basis) reduced fat DDGS (pDDGS), a 10% DDGS treatment with an alternative distillers grains source (aDDGS), and a 10% canola meal (CanM) treatment. Results suggest that milk production can be maintained when feeding these byproducts. However, energy utilization differences are observed, specifically in gross energy, digestible energy, metabolizable energy and energy balance (Mcal/kg of DM). The alternative source of DDGS contained the greatest amount of gross energy, digestible energy, and metabolizable energy. The control and the alternative source of DDGS contained the greatest energy balance. Dry matter, organic matter, crude protein, and neutral detergent fiber digestibility differences were also observed between treatments, specifically the control and the DDGS treatments had the greatest digestibility. In the second experiment, a comparison of sample preparation methods of urine to be analyzed for energy content by bomb calorimetry was conducted. The two methods to be tested included a lyophilization and oven drying method. Results of this study suggest that there were significant differences in gross energy content and total urine energy depending on which sample preparation method was used. The lyophilization method resulted in a greater gross energy and total urine energy compared to oven drying method, creating a negative method difference.
Download or read book INRA feeding system for ruminants written by INRA and published by BRILL. This book was released on 2023-11-27 with total page 639 pages. Available in PDF, EPUB and Kindle. Book excerpt: The INRA Feeding System for Ruminants has been renewed to better address emerging challenges for animal nutrition: prevision of productive responses, product quality, animal health and emissions to the environment, in a larger extent of breeding contexts. The new system is mainly built from meta-analyses of large data bases, and modelling. The dietary supply model accounts for digestive interactions and flows of individual nutrients, so that feed values depend on the final ration. Animal requirements account for variability in metabolic efficiency. Various productive and non-productive animal responses to diets are quantified. This book presents the whole system for dairy and meat, large and small ruminant production, including specificities for tropical and Mediterranean areas. The first two sections present biological concepts and equations (with their field of application and statistical accuracy) used to predict intake (including at grazing) and nutrient supply (Section 1), animal’s requirements and multiple responses to diets (Section 2). They apply to net energy, metabolisable protein and amino acids, water, minerals and vitamins. Section 3 presents the use of concepts and equations in rationing with two purposes: (1) diet calculation for a given performance objective; and (2) prediction of the multiple responses of animal to diet changes. Section 4 displays the tables of feed values, and their prevision. All the equations and concepts are embedded in the fifth version of INRAtion® software for practical use.

This book was released on 2003-04-07 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: Air Emissions from Animal Feeding Operations: Current Knowledge, Future Needs discusses the need for the U.S. Environmental Protection Agency to implement a new method for estimating the amount of ammonia, nitrous oxide, methane, and other pollutants emitted from livestock and poultry farms, and for determining how these emissions are dispersed in the atmosphere. The committee calls for the EPA and the U.S. Department of Agriculture to establish a joint council to coordinate and oversee short - and long-term research to estimate emissions from animal feeding operations accurately and to develop mitigation strategies. Their recommendation was for the joint council to focus its efforts first on those pollutants that pose the greatest risk to the environment and public health.
