This book was released on 2004 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: The beef industry is in a constant search for new feedstuffs to be used in the production process. This occurs for several reasons. Nutritional support of gain in growing beef cattle needs to, at minimum, match improvements realized in the genetic capability for growth. Feed costs constitute one of the largest beef production costs and economics has dictated that feed cost per kilogram of gain be reduced to remain competitive in the world market. Manufacturing of goods for human consumption has created numerous by-products with little economic value for human use. Dried distillers grains with solubles (DDGS), a by-product of ethanol production, represents a product which could be used as a replacement for soybean meal (SBM) in cattle rations. A national need for fuel-grade ethanol has driven dramatic increases in its production and subsequent increases in DDGS supply. The state of Missouri has been targeted as an area for development of ethanol production. The by-product of the process, DDGS, is high in protein, digestible fiber, and lipid content. This makes it a potential Nitrogen and energy source for ruminant rations. A series of experiments was conducted to evaluate the impact of DDGS as a protein and energy source in beef cattle. We compared DDGS and SBM in growing heifers consuming corn-silage, soyhull, and corn-based diets to evaluate the performance and cost-effectiveness of the two supplements. Similar dietary N levels were evaluated. Inclusion of DDGS in the diet resulted in increased final weight, ADG, DMI, and lower cost of gain as compared to heifers consuming SBM. Grazing is utilized in a large portion of Missouri cattle production, with summer generally requiring supplementation. A study was conducted which evaluated increasing levels of DDGS for heifers grazing tall fescue. Performance criteria were evaluated for animals receiving 0.45, 0.91, or 1.36 kg DDGS and a 0.1 kg soyhull negative control. Average daily gain was quadratically improved as level of DDGS in the diet was increased, with 0.91 kg DDGS providing the greatest ADG. Intake of forage DM and cost of gain were not affected by treatment. The final experiment examined the post-ruminal amino acid flow of mature steers consuming timothy hay and supplemented with DDGS, SBM, a SBM/DDGS blend, or negative control. Supplementation increased duodenal flow of total essential and non-essential AA, while Met, Leu, and Trp were linearly increased by greater inclusion of DDGS in the diet. Dried distillers grains with solubles appears to be a valid replacement of SBM in highforage growing diets.

This book was released on 2000-05-16 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: As members of the public becomes more concious of the food they consume and its content, higher standards are expected in the preparation of such food. The updated seventh edition of Nutrient Requirements of Beef Cattle explores the impact of cattle's biological, production, and environmental diversities, as well as variations on nutrient utilization and requirements. More enhanced than previous editions, this edition expands on the descriptions of cattle and their nutritional requirements taking management and environmental conditions into consideration. The book clearly communicates the current state of beef cattle nutrient requirements and animal variation by visually presenting related data via computer-generated models. Nutrient Requirements of Beef Cattle expounds on the effects of beef cattle body condition on the state of compensatory growth, takes an in-depth look at the variations in cattle type, and documents the important effects of the environment and stress on food intake. This volume also uses new data on the development of a fetus during pregnancy to prescribe nutrient requirements of gestating cattle more precisely. By focusing on factors such as product quality and environmental awareness, Nutrient Requirements of Beef Cattle presents standards and advisements for acceptable nutrients in a complete and conventional manner that promotes a more practical understanding and application.

This book was released on 2014 with total page 86 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supplementing cattle on grass is an effective way of increasing animal efficiency and grass utilization. Distiller grains plus solubles (DGS) supplementation has been repeatedly proven as an effective supplement by providing ruminally undegradable protein (RUP), fat, and highly digestible fiber. The effects of monensin supplementation on grazing cattle are variable. Although some research has shown a decrease in forage organic matter intake (FOMI), the popular belief is monensin increases ADG while maintaining DMI in a grazing situation. Two experiments were designed to observe the effects of DGS and monensin supplementation on cattle grazing smooth bromegrass. In the first study, ADG and modified distillers grains plus solubles (MDGS) intake were measured for cattle grazing smooth bromegrass. Steers were supplemented MDGS at 0.05, 0.4, 0.6, or 0.8% BW and were either given 0 or 200 mg monensin. In the second study, FOMI was estimated when cattle grazing smooth bromegrass were supplemented with MDGS at 0.4% BW was given 0 or 200 mg monensin. In the first study, monensin did not affect ADG (P = 0.53). There was a monensin x MDGS intake interaction (P = 0.05). Monensin decreased MDGS consumption only when supplement was offered at 0.8% BW (P = 0.01). In the second study, monensin tended to decrease FOMI by 9% (P = 0.10).

Download or read book Effects of a Novel Pressed Dried Distillers Grain Block During Late Gestation on Dry Matter Intake and Cow Performance and the Impacts of Feed Efficiency on Reproductive Performance written by Chance L. Marshall and published by . This book was released on 2014 with total page 97 pages. Available in PDF, EPUB and Kindle. Book excerpt: Feed costs account for approximately 70% of total production costs in beef cattle operations. Therefore, considering ways to reduce feed intake is necessary to remain profitable. Cattle grazing high elevation range lands of the northwestern United States typically require protein and/or energy supplementation during the winter months when nutrient requirements are increased. Selection of a supplementation program that is effective and minimizes additional costs is imperative. The first study was conducted to 1) evaluate effects of supplementation with a self-limiting pressed dried distiller's grain block, SweetPro ® 16, on cow BW, body composition, and hay intake in late gestation, 2) monitor birth weights and growth characteristics of subsequent offspring. It was determined that supplementation with the SweetPro® 16 decreased intake of forage and increased cow BW and BCS. However, supplementation did not affect body composition, circulating progesterone concentrations, birth weight or pre-weaning growth of offspring. While nutrition represents the largest cost to cow-calf producers, a successful reproductive program is the primary factor affecting profitability. Selection for highly feed efficient cattle may be related to decreased fat deposition leading to increased age at puberty. The second study was conducted to determine if selection for feed efficient heifers may result in decreased reproductive efficiency. Specifically, our objectives were to evaluate the effects of residual feed intake (RFI) ranking on BCS, growth, age of puberty, conception rate, pregnancy rate, and ovarian antral follicle count (AFC). An additional objective was to compare the results of actual RFI for these heifers versus their predicted residual feed intake (PRFI) estimated by the Cornell Cattle Value Discovery System (CCVDS). It was determined that when RFI was predicted using CCVDS, weaning weights, ADG, pre-breeding BW and BCS were greater for heifers with high PRFI compared to heifers with low PRFI. In addition, AFC did not differ between PRFI rankings but high PRFI heifers tended to have greater first service conception rates and did have greater overall pregnancy rates compared to low PRFI heifers. Alternatively, actual RFI rank did not affect BW, body composition, AFC, or fertility but low RFI heifers consumed 21% less feed inputs compared to high RFI heifers. The Cornell system was not a valuable tool for predicting individual heifer RFI ranking, which suggests that performance tests are still necessary for reliable RFI rankings of growing beef heifers.

Available in PDF, EPUB and Kindle. Book excerpt: Distillers grains plus solubles (DGS) have been widely utilized in beef cattle diets. Fractionation of the corn kernel pre- and post-fermentation has changed the composition of DGS and allowed for the production of other feed byproducts over time. The use of fractionated DGS and other feed byproducts from the ethanol industry has not been heavily researched in beef cattle diets. Three experiments were conducted to evaluate the effect of feeding high protein distillers grains (HiPro DDG) and corn bran plus solubles (Bran + Solubles) in beef cattle diets. Experiment 1 evaluated the effect of byproduct type on finishing performance and carcass characteristics. Experiment 2 evaluated the effect of byproduct type on nutrient digestibility, ruminal pH, ruminal VFA production, and in vitro gas production. Byproducts replaced corn at 40% of diet DM in Exp. 1. Experiment 3 compared feeding Bran + Solubles to wet DGS at 20 and 40% of diet DM compared to a corn control. In Exp. 2, Feeding HiPro DDG or Bran + Solubles resulted in decreased digestibility compared to corn or traditional wet and dry DGS, but increased energy intake. Traditional wet and dry DGS also resulted in decreased digestibility while energy intake was increased. Volatile fatty acid profiles and pH parameters were not different across treatments. Feeding HiPro DDG and Bran + Solubles improved gains and feed efficiency compared to traditional dry or wet DGS and corn. Compared to wet DGS, Bran + Solubles resulted in similar performance and carcass characteristics. Increased inclusion of both byproducts resulted in a linear increase in carcass weight. Overall, nutrient digestibility for HiPro DDG or Bran + Solubles is similar to traditional wet or dry DGS while performance was increased.

Sudbeck and published by . This book was released on 2014 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Heifers (n = 229; 225 kg ± 2) were used in a 2 x 2 x 2 factorial to determine the effects of longterm exposure to corn distillers grains plus solubles (DGS) on meat quality characteristics. Factors included supplementing 0.91 kg (LW) or 2.3 kg (HW) modified DGS (MDGS) while grazing corn stalks; 0.6% BW dry DGS (SS) daily or none (NS) during summer grazing; and finishing diet containing 40% wet corn gluten feed (CGF) or 40% MDGS (DGF) on a DM basis. An interaction was observed within CGF for discoloration, with SS increasing discoloration 30%; but no differences between SS or NS from DGF cattle. Discoloration scores for DGF increased compared to CGF d 6 - 7 and d 4 - 6 for steaks aged 7 and 21 d, respectively. Supplementing with DGS did not further reduce the color stability of retail beef of DGF finished cattle; however, DGS supplementation prior to finishing can affect beef quality when DGS are not included in the finishing diet. In the second study, crossbred steers (n = 336) were utilized in a 2 x 3 factorial evaluating duration of OmniGen – AF supplementation (0, 28, or 56 d) at 4 g / 45.5 kg BW and supplementation of ractopamine hydrochloride (RAC) at 300 mg/ steer daily for the last 28 days of finishing or no supplementation. No Omnigen – AF by RAC interaction or OmniGen –AF effects were observed for any feedlot performance or carcass characteristics measured. Supplementing RAC increased ADG 0.5 kg, increased FBW 10.0 kg, and increased LM area 0.9 cm2 compared to NORAC.

This book was released on 2012 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this study was to determine the differences in voluntary intake and digestibility of moderate-quality, long-stem fescue hay (9.5% crude protein (CP); dry matter (DM) basis) by steers consuming 4 levels of distillers dried grains with solubles (DDGS) (27.7% CP; DM basis). Four ruminally cannulated Hereford steers (avg 364 ± 63 kg initial body weight (BW)) were housed in individual pens (4 x 4 m) and randomly assigned to treatment blocks in a completely randomized, replicated 4x4 Latin Square experimental design. Treatments were Control (C), Low (L), Moderate (M) and High (H) and were fed at 0, 0.2, 0.4, and 0.8% of BW daily, respectively. Each period consisted of a 10 day adaptation and a 7 day collection, during which hay intake, orts, and total fecal output were measured daily, followed by a 10 day washout. Data were analyzed using GLM Procedure of SAS, where the model included the fixed effects of treatment and period and steer was included as a random variable. Total dry matter intake increased (P= 0.02) and total organic matter intake increased (P = 0.003) as DDGS supplementation increased. Total tract, apparent organic matter digestibility increased (P = 0.01) as DDGS supplementation increased. Total NDF and ADF intake and digestibility was not different (P ≥ 0.19) between treatments. When fed at 0.4% of BW or greater, DDGS supplementation decreases voluntary intake of moderate-quality, long-stem fescue hay.

Download or read book Effect of Dried Distillers Grains with Solubles on Greenhouse Gas Emissions from Beef Cattle written by Martin Hünerberg and published by . This book was released on 2014 with total page 187 pages. Available in PDF, EPUB and Kindle. Book excerpt: Four experiments were conducted to determine the impact of dried distillers' grains with solubles (DDGS) on greenhouse gas (GHG) emissions from beef cattle. The first compared in vitro methane (CH4) production from corn DDGS (CDDGS, ~30% crude protein [CP]) and wheat DDGS (WDDGS, ~40% CP dry matter [DM]). Wheat DDGS or CDDGS replaced barley silage at 20, 40, 60, 80 and 100% DM. Methane (mg CH4/g DM) was lower for CDDGS than WDDGS at up to 80% DM. In a second experiment, heifers fed a growing (high silage) diet showed a reduction in CH4 (g CH4/kg DM intake [DMI]) when 35% barley grain and 5% canola meal DM were replaced with CDDGS (10.0% fat DM). Inclusion of 40% WDDGS (4.1% fat DM) had no effect on enteric CH4 emissions. In contrast, feeding 40% DM WDDGS with added corn oil (9.5% fat DM) reduced CH4 to the same extent as CDDGS. In a third experiment, replacing 40% DM barley grain with CDDGS (9.7% fat DM) in a finishing (high grain) diet reduced CH4 (g/kg DMI). Whereas feeding 40% DM WDDGS along with corn oil (9.9% fat DM) resulted in similar CH4 losses as CDDGS. Results from both in vitro and in vivo experiments indicate that the higher fat content of CDDGS vs. WDDGS was responsible for CH4 reductions. The benefit of replacing 40% DM barley grain with CDDGS or WDDGS on GHG emissions from beef production was further evaluated using life cycle assessment. Replacing barley grain with CDDGS or WDDGS increased N intake and subsequently N excretion. Increased N excretion was predicted to outweigh reductions in CH4 through increased formation of nitrous oxide (N2O). Therefore, feeding CDDGS and WDDGS resulted in 6.3 and 9.3% higher GHG intensity (kg CO2 equivalent [CO2e]/kg beef) compared to the control. To reduce the environmental impact, DDGS should not be fed at inclusion levels that exceed N requirements of feedlot cattle.
