This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Cattle consuming low-quality forage may have decreased forage organic matter intake as a result of decreased nitrogen (N) intake. To date, a value has not been assigned to dried distillers' grains as a protein supplement to cattle consuming low-quality Bermudagrass forage. To address this shortcoming in the data, 13 duodenally and ruminally fistulated steers were arranged in an incomplete 13 x 4 Latin square with 13 treatments and 4 periods. Treatments were arranged as a 4 x 3 factorial plus a negative control (NC), which received no supplement. The first factor consisted of 4 levels of supplemental protein provided at 52, 104, 156, and 208 mg N/kg BW. The second factor consisted of one of three supplemental protein sources, cottonseed meal (CSM), dried distillers' grains (DDG), and dried distillers' grains plus urea (DDGU). Total digestible organic matter (TDOMI), and total organic matter intake (TOMI) increased in response to the increasing level of supplemental protein (P

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.

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.

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.

Download or read book Effects of Protein Supplementation and Forage Quality on Intake and Digestion in Cattle written by Jamie Kunkel and published by . This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In many pasture and rangeland scenarios, low-quality forages (6-8% CP) are the primary energy source for some portion of the year. At these times, energy is typically the first limiting nutrient to the ruminant. Low-quality forages are generally not limited in availability; however, the high cell wall content and reduced levels of CP prevent ruminants from being able to extract the harvested energy. Without provision of supplemental nutrients, the available energy may be inadequate to meet performance expectations. Protein supplementation during periods of inadequate forage quality has been observed to alleviate ruminal nitrogen deficiencies and increase forage utilization. Increased forage utilization translates into greater energy extraction allowing for increased animal performance. The first trial was conducted to evaluate the effects of utilizing non-protein nitrogen (a slow-release urea compared to urea) on intake and digestion of beef steers consuming low-quality bermudagrass hay. Steers were provided ad libitum access to a low-quality bermudagrass hay (7.3 % CP and were ruminally dosed once daily with either urea or slow-release urea (SRU) at levels to provide 0, 64, 128, or 192 mg of N/kg of initial BW per day. Additionally, steers were supplemented with glycerol at levels of 0 or 0.1% of initial BW per day. Total OMI and forage OMI (FOMI) increased quadratically (P

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 2012 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: Steers consuming 3.39 and 4.52 kg DDG, had increased (P = 0.05) NH3-N. Level of DDG affected PUN (P = 0.05) and tended (P = 0.09) to effect NEFA and glucose concentrations. Experiment 3, a Latin square design, all steers received RBS and were assigned to: 1) RBS only; 2) DDG supplement at 0.33% BW; 3) DDG supplement at 0.66% BW; or, 4) DDG supplement at 1% BW. There was a quadratic (P = 0.05) response to the amount of DDG supplemented on RBS DMI, total DMI intake, and total tract apparent DM digestibility and a linear (P P = 0.02) with amount of DDG and a cubic response (P 3-N concentrations. In conclusion, addition of SBM had no effect on heifer growth or reproductive performance, and increasing levels of DDG increased total DMI, digestibility, fecal output, and altered rumen parameters.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: A 3-yr study evaluated effects of supplementing modified wet distillers grains with solubles during summer grazing and subsequent feedlot sorting on long yearling steers. During summer grazing, supplemented steers had greater ADG and were more profitable than non-supplemented steers. At feedlot entry, supplemented steers were 48 kg heavier than non-supplemented steers. Feed efficiency and DMI were not different between supplementation treatments during finishing. Supplemented steers were fed 24 fewer days to reach a similar 12th rib fat thickness, had greater LM area, and lower marbling compared to non-supplemented steers. Overall profitability favored supplementing steers because less expensive summer gains also reduced feedlot inputs. Sorting on feedlot entry BW increased HCW, marbling, and YG. However, percentage overweight carcasses and profitability were similar between the sort treatments. An ongoing 3-yr trial was conducted to elucidate effects of weaning date and pre-partum nutrition on cow-calf productivity in a spring calving system. The first 2-yr of data found dams weaned in October weaned cows grazing winter range had greater BCS and BW compared to December weaned cows pre-calving. Dams on a higher nutritional plane from winter grazing treatment had greater BCS and BW prior to parturition and breeding. However, subsequent pregnancy rates for cows were similar among weaning and winter grazing treatments. Calves born to dams on a higher nutritional plane had greater BW in October and December, and adjusted weaning BW. There were no differences in percentage cycling prior to breeding or pregnancy rate of heifer progeny. Steer progeny had greater HCW and 12th rib fat thickness at harvest. Net change in return was greatest when October weaned dams were wintered on corn residue and December weaned dams were on winter range with 0.91 kg supplement if calves were sold at weaning. When ownership was retained, steer progeny born to dams on corn residue during winter grazing resulted in the greatest net change in return.
