Available in PDF, EPUB and Kindle. Book excerpt: Rapeseed mustard cake (RMC) can be readily used as a protein supplement in lactating cows diet due to its availability and being cheaper than other oil cakes. The use of RMC as protein supplement is constrained due to its higher level of glucosinolates that have variable adverse effect on palatability, intake, nutrient utilization, thyroid hormone status and overall performance of the animals. The new improved varieties of rapeseed mustard cultivar which is low in both erucic acid (

Download or read book Production and Physiological Effects of Including Soybean Meal Or Canola Meal in Dairy Cow Diets from the Close up Dry Period to Mid lactation written by Jordan Matthew Kuehnl and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Protein-rich feedstuffs are used in dairy cow diets to increase overall dietary crude protein to maximize production. Traditionally, soybean meal (SBM) has been the primary protein source utilized in the United States. However, increasing knowledge of the positive production effects when substituting canola meal (CM) for other protein sources such as SBM is challenging this notion. While there is a long history of research demonstrating positive production effects during middle and late lactation, a scarcity of information exists for characterizing the effects of feeding CM during the close-up dry period and early lactation. The primary objective of the first experiment was to determine the effect of feeding isonitrogenous diets with SBM or CM as the primary protein source during the close-up dry period and early lactation on production measures in Holstein dairy cows. Furthermore, we sought to characterize the effects on temporal plasma hormone and metabolite concentrations, diet digestibility, and urinary excretion of purine derivatives. Dry matter intake increased pre- and postpartum for cows fed the diets with CM compared to SBM. Additionally, cows fed the diets with CM tended to increase milk yield and decreased milk urea nitrogen compared to cows fed the diets with SBM postpartum. Plasma triiodothyronine concentrations decreased pre- and postpartum for cows fed the diets with CM compared to SBM, corresponding to increased milk yield. Diet digestibility decreased pre- and postpartum and intestinal microbial N flow decreased postpartum for cows fed the diets with CM compared to SBM. The objective of the second experiment was to determine the effect of feeding isonitrogenous diets with SBM or CM as the primary protein source during mid-lactation on production and physiological measures in Holstein dairy cows determined to have high or low residual feed intake. Dry matter intake increased for cows fed the diet with CM compared to SBM. A diet × week interaction occurred for milk yield, with increased persistence for cows fed the diet with CM compared to SBM. Plasma triiodothyronine concentrations decreased and insulin concentrations increased for cows fed the diet with CM compared to SBM, corresponding to increased milk and milk protein yields.

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

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.

Download or read book Canola Meal as a Protein Supplement in Dairy Rations written by Jorge Ml Sanchez and published by . This book was released on 1981 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: A four months continuous feeding trial was conducted to evaluate Canola meal as a single protein supplement in complete dairy rations. Thirty high producing Holstein cows in the second week of lactation were randomly alloted in groups of ten to one of three isonitrogenous (15% CP) and isocaloric (1.6 Mcal/kg of NE lactation) rations, containing either Canola meal (38% CP), Soybean meal (46% CP) or Cottonseed meal (41% CP). Productive and physiological parameters were analysed. Milk production, both actual and 4% FCM, did not differ (P>.05) among diets. However, Canola meal fed cows tended to produce more milk than animals in other treatments. No differences (P>.05) were found for milk protein, fat, total solids nor solids not fat percentages. Milk solids not fat yield was the only milk component produced in different (P=.024) amounts between diets and was mainly influenced by milk production. Canola meal glucosinolates, tannins and phytate did not impair feed intake, however animals in this group showed lower feed conversion. Rumen total volatile fatty acid content was higher (P=.031) for Canola meal and Soybean meal groups. No significant differences (P>.05) were found for rumen volatile fatty acid composition, acetic:propionic ratio, ammonia nitrogen or pH. Urea nitrogen, total protein and albumin plasma concentrations were not different (P>.05) among diets, suggesting that Canola, Soybean and Cottonseed meals were equal as protein supplements. White blood cells was the only hematological parameter (packed cell volume, red blood cells, white blood cells and hemoglobin were analysed) that significantly differed (P=.011) among diets. Soybean meal fed cows showed higher white blood cell count, which is believed to have a physiological origin. Triiodothyronine uptake values were significantly higher (P=.015) in Soybean meal fed cows. However, Triiodothyronine uptake as well as Tetraiodothyronine concentration and Free Thyroxine Index correspond to euthyroid values, indicating that Canola meal glucosinolates did not affect the thyroid metabolism of the experimental animals. Results indicate that Canola meal may be used as a single protein supplement in rations for high producing cows, to satisfactorily replace traditional sources of protein such as Soybean meal and Cottonseed meal.

Book excerpt: This book presents strategies for feeding energy and protein supplements to pasture-fed dairy cows and examines the potential economic benefits. Effective supplementary feeding of concentrates is critical to the success of all dairy farms. This book is a substantially revised edition of 'Feeding Concentrates: Supplements for Dairy Cows' DRDC 1993. It focuses on feeding concentrates to pasture fed cows to achieve high milk production per cow per hectare, and will assist farmers to decide which supplements give the best results in their particular situation. The benefits that arise from supplementary feeding include higher stocking rates, promotion of growth in heifers and young cows; better body condition score and increased lactation length when pasture is less available; improved pasture use; reduced cost per tonne of pasture eaten; flexibility to increase milk production when milk prices are high; and increased milk protein content when the energy content in pasture is low. This edition has thoroughly reviewed the issues and clearly documents the results of research particularly for grains supplementation. The summaries and recommendations in each chapter will be particularly helpful to dairy farmers in making best management decisions relating to concentrate feeding.

Available in PDF, EPUB and Kindle. Book excerpt: Variations in feeding frequency may lead to difference in utilization of dietary nutrients. The effects of feeding frequency have been tested in growing pigs and finishing pigs using respiratory quotient and postprandial kinetics of plasma metabolites. A reduced feeding frequency resulted in an increased lipogenesis and proteolysis shortly after the meal both in growing and finishing pigs. Nevertheless, growing and finishing pigs exhibit different metabolic pathways when feeding frequency is reduced.

Book excerpt: Seminar paper from the year 2017 in the subject Veterinary medicine, Jimma University College of Agriculture and Veterinary Medicine, language: English, abstract: Objective of this review is focus on effect of feeding protected fat and protected protein on milk yield and its composition and how these nutrients are protected. Many researchers in this review investigate that the responses are highly dependent on the type of fat and protein supplement and the stage of lactation. A higher milk response was observed with saturated than with unsaturated fat supplements. Diet with added fat increase milk production compared with a control diet without added fat in cows. Feeding of bypass fat resulted in significant increase in milk yield and Fat Corrected Milk yield particularly in early lactation. The source of Protected fat are (origin (animal, plant, processed or whole oilseeds, calcium salts) and Cereal Grains such as corn, wheat, Barly, oil seeds, sun flower, cotton seed, soybeans and canola). The supplementation of protected protein in the diets of lactating animals increases the milk yield due to proportionate increase in the supply of amino acids to the host postruminally Milk yield in cows fed protected methionine for the whole experimental period was numerically higher than in cows of the other groups. However, the difference was not statistically significant .At the centeral high land of Ethiopia the Treatment of shredded wheat and barley straw with urea, molasses, salt and water prior to feeding is a technology that should be considered . Cows with excessive body tissue mobilisation at this stage may take up to 20 weeks to regain a positive energy balance status. Key words milk yield, composition ,protected fat , protein protected
