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 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.
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 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.

This book was released on 2017 with total page 119 pages. Available in PDF, EPUB and Kindle. Book excerpt: Corn condensed distillers solubles (CDS) is a protein and energy dense by-product from dry-milled production of ethanol. Recent oil extraction has posed modifications to the nutrient profile of CDS, suggesting that de-oiled CDS needs to be re-evaluated in beef cattle diets. Three experiments were conducted to evaluate the effects of CDS in high-concentrate diets, forage-based diets, as well as evaluate the effects of CDS on diet digestibility and rumen fermentation parameters in forage-based diets. Feeding CDS in high-concentrate diets up to 20% of the diet DM or in combination with wet distillers grains plus solubles (WDGS) improved performance and resulted in greater energy value compared to corn. Feeding values of 20% CDS or the combination of 16% CDS and 20% WDGS were 147 and 129% compared to corn, respectively. Feeding CDS in forage-based diets up to 40% of the diet DM diminished performance and resulted in a lesser energy value compared to corn. Linear decreases were observed in total tract digestibility of NDF and the acetate to propionate ratio in rumen fluid. Double-cropped forages following corn harvest offer livestock producers an opportunity to extend their grazing season on high quality forage in the fall. Additionally, crop producers may benefit from the implementation of grazing animals due to added soil nutrients and removal of residue. Therefore, an experiment was conducted to evaluate the effects of double-cropped oats following corn silage (CS) or high-moisture corn (HMC) on calf gains, forage production, and subsequent cash crop yields. Oats seeded after CS produced more forage biomass than oats seeded after HMC. Both treatments produced high quality oats (22% CP, 39% NDF, and 24% ADF averaged across treatments). Calf gains were greater grazing oats following CS compared to HMC at 1.10 and 0.84 kg / d, respectively. Across 1-yr of data, subsequent cash crop yields were not different for HMC and soybeans with increased CS yields in both covered/grazed and non-covered/non-grazed treatments compared to the covered/non-grazed treatment..

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
