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 2018-03-13 with total page 31 pages. Available in PDF, EPUB and Kindle. 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
Download or read book Nutrient Utilization Lactational Performance and Profitability of Dairy Cows by Feeding Protein Supplements in High Forage Lactation Diets written by Kathryn Neal and published by . This book was released on 2014 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the increasing cost of soybean meal and concerns of excess N being excreted into the environment, new protein supplements have been developed. Two products that have shown potential in increasing N utilization efficiency are slow release urea (SRU; Optigen) and ruminal escape protein derived from yeast (YMP; DEMP). The objective of this study was to assess the effects of feeding these 2 supplements in high-forage [(54% of total dietary dry matter (DM)] dairy diets on nutrient utilization, feed efficiency, lactational performance of dairy cows, and their impacts on income-over feed costs. Twelve multiparous dairy cows were used in a triple 4 ©7 4 Latin square design with one square consisting of ruminally cannulated cows. Treatments included: 1) control, 2) SRU-supplemented total mixed ration (TMR, SRUT), 3) YMP-supplemented TMR (YMPT), and 4) SRU and YMP-supplemented TMR (SYT). The control consisted only of a mixture of soybean meal and canola meal (SBMCM) in a 50:50 ratio. The SRU and the YMP were supplemented at 0.49% and 1.15% DM, respectively. The experiment consisted of 4 periods lasting 28 d each (21 d of adaptation and 7 d of sampling). Cows fed YMPT and SYT had decreased intake of DM, and all supplemented treatments had lower crude protein intake compared to those fed the control. Milk yield tended to have the greatest increase in YMPT compared with the control (41.1 vs. 39.7 kg/d) as well as a tendency for increased milk fat and protein yields. Feed efficiencies based on yields of milk, 3.5% fat-corrected milk, and energy-corrected milk increased at 10-16% due to protein supplementation. Cows fed with protein supplements partitioned less energy toward body weight gain, but tended to partition more energy toward milk production. Efficiency of use of feed N to milk N increased by feeding SRUT and YMPT, and milk N-to-manure N ratio increased in YMPT. Cows fed SRUT or YMPT tended to improve income-over feed costs. Overall results from this experiment indicate that replacing SBMCM with SRU and YMP in high-forage dairy diets can be a good approach to enhance dairy profitability through improved nutrient utilization efficiencies by lactating dairy cows.

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 Effects of Feeding High Moisture Corn Grain with Slow Release Urea in Dairy Diets on Lactational Performance Energy and Nitrogen Utilization and Ruminal Fermentation Profiles by Lactating Cows written by Braden M. 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.

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 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.
