This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Recent trends to develop farmland into improved irrigated pastures raise questions regarding the profitability of creep supplementing terminal-sired calves on these production systems. This study was initiated to answer these questions. Two previously established adjacent sprinkler-irrigated plots were separated into 2 paddocks. One plot (3.4 ha) consisted of a monoculture of Seine tall fescue while the other plot (3.9 ha) consisted of a mixture of Seine tall fescue, AC Grazeland Alfalfa, and Norcen birdsfoot trefoil. The mixture of the second plot consisted of 50% tall fescue, 37.5% alfalfa, and 12.5% birdsfoot trefoil. Plots were designated as monoculture no-creep supplement (MONOC) (1.7 ha), monoculture with creep supplement (MONOS) (1.7 ha), mixed forage no-creep supplement (MIXC) (1.95 ha), and mixed forage with creep supplement (MIXS) (1.95 ha). Twenty-four spring calving cow-calf pairs were stratified into 4 groups based on calf body weight, sex, breed, dam body weight, dam BCS, and breed. Management-intensive grazing practices were implemented with cattle receiving a new allotment of forage at 0800 daily. Cattle grazed in a west-to-east direction across the pasture completing a grazing circuit every 24 to 30 d. Pasture forage production was estimated using a 0.163 m2 clip-plot. Forage production each period was highest for cattle grazing MIXS (4492 kg DM/ha) followed by MIXC (4116 kg DM/ha) (P=.58). Production from the MIX plot differed from MONO plot (P

This book was released on 2006 with total page 63 pages. Available in PDF, EPUB and Kindle. Book excerpt: With public rangeland access diminishing one option for cow/calf producers is use of irrigated pastures. Five different treatment paddocks with three replicates each were established: (1) alfalfa, (2) meadow brome, (3) birdsfoot trefoil, (4) tall fescue, (5) an equal surface area mixture of the above four forages. Spring calving cow-calf pairs were assigned to the study (2 pairs/paddock). Total forage DM produced, carrying capacity, and calf ADG were monitored for each treatments. Due to high calf gains and high carrying capacity the tall fescue treatment resulted in the greatest economic return. Cattle on the mixed pastures were evaluated for grazing behavior. Observations were conducted to see if cattle exhibited nutritional wisdom when selecting forages. For the winter grazing 3 paddocks each of a silage-type corn, or forage-type sorghum were grazed by dry pregnant beef cows. Cow BW change and forage production were monitored. Similar results were obtained for both forages.

This book was released on 2002 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two grazing systems were evaluated over three years to compare the amounts of hay fed, cow weight and condition score changes, growing animal production, and effects of management systems on the mass and nutritive value of forages. In a minimal land (ML) grazing system, replicated 8.1-ha smooth bromegrass-orchardgrass-birdsfoot trefoil (SB-OG-BFT) pastures were rotationally stocked with six spring-calving cows and calves. Excess forage was harvested as first-cutting hay, then the entire area was rotationally stocked the rest of the season. At termination of summer grazing, cows were fed hay in a drylot. In the year-round (YR) grazing system, 8.1-ha SB-OG-BFT, 6.1-ha smooth bromegrass-red clover (SB-RC), and 6.1-ha tall fescue-red clover (TF-RC) pastures were stocked with six spring-calving cows and calves, 12 stocker animals (previous season's calf crop) and six fall-calving cows. First-cutting hay was harvested from TF-RC and SB-RC pastures simultaneous to the ML system. Second-cutting forage was strip-grazed by cows, while stocker animals remained in SB-OG-BFT pastures. Stocker animals were removed from pastures and finished and cows were again stocked in SB-OG-BFT pastures, while forage was allowed to accumulate in TF-RC and SB-RC pastures. During winter, spring-calving cows sequentially strip-grazed corn crop residue fields and stockpiled SB-RC pastures. Simultaneous to initiation of corn crop residue grazing, fall-calving cows with calves strip-grazed stockpiled TF-RC pastures. Hay was supplemented during winter when weather conditions limited grazing. Fall-calving cows had greater (P [Less than or equal to symbol] 0.03) body condition scores at all production stages except post-breeding (P = 0.13) and post-weaning (P = 0.53) compared to either group of spring-calving cows. Total growing animal production was 27 kg/cow greater (P = 0.01) from the YR grazing system than the ML grazing system. The amount of hay fed in the ML grazing system was 896 kg DM/cow-stocker pair greater (P

Download or read book Impact of Grazing Management Monensin Supplementation and Weed Density on Beef Cow Calf Performance and Pasture Production written by Leanna Duppstadt and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Monensin (Rumensin 90, Elanco Animal Health; Greenfield, IN) is a direct-fed ionophore that alters ruminal fermentation and has been shown to increase energy efficiency by altering VFA production in the rumen, resulting in improved forage utilization. This suggests that monensin has the potential to alleviate the effects of a cool-season perennial pasture summer slump. Weeds compete with desired forages for natural resources and can have a negative impact on livestock and pasture production. Grazing management strategies are implemented to encourage desirable forage growth and discourage the growth of undesirable species; suggesting that the implementation of rotational grazing could alleviate competition with weeds. In experiment 1, 32 spring-calving, Angus-based cow-calf pairs were stratified into pastures based on body weight (BW) and blocked by age. The study was conducted using 2x2 factorial, for 3 years (2015-2017) with 56-d grazing seasons each year. All cows were limit-fed wheat mid-based pellets with (MON; 200 mg/cow/day) or without monensin (NOMON). Treatments included 1) continuous grazing without monensin supplementation (CONT NOMON); 2) continuous grazing with monensin supplementation (CONT MON); 3) rotational grazing without monensin supplementation (ROT NOMON); and 4) rotational grazing with monensin supplementation (ROT MON). Cows in ROT were rotated every 7-d and desired forage height was maintained by put-and-take stocking. Precipitation was highest in June and July for Years 1 and 3, and lowest in Year 2. Temperatures were highest in July and August of Year 2 and this in combination with low precipitation created the ideal conditions for a true summer slump in PA in 2016.There were no grazing x supplement interactions, nor were there main effects of monensin inclusion or grazing management for Years 1 and 3 (P = 0.80 and P = 0.77, respectively). In Year 2, all cows lost BW and body condition score (BCS) from d 0 to 56, but cows on ROT receiving MON lost the least (grazing x supp: BW (P = 0.02) and BCS (P 0.01)).There were no main effects or interactions for carrying capacity (CC) or stocking rate (SR) in Years 1 and 3. Cows on ROT grazed pastures and cows receiving MON had greater CC and SR for grazing treatment (P = 0.07) and supplement treatment (P

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.

Available in PDF, EPUB and Kindle. Book excerpt: This book covers the subject of grasslands used for grazing livestock. Grasslands can be split into improved and unimproved pastures (also a sub-set of rangelands). Land used for livestock industries occupy 70% agricultural land and about 40% of total land and produce 40% of agricultural gross domestic product (FAO, 2005; Steinfeld et al., 2006). Increasing populations and incomes, coupled with a change in diets and urbanisation in the developing world, is enhancing demand for pasture-based products (Devine, 2003; Schmidhuber and Shetty, 2005). For example, milk and meat production is predicted to double to just over 1 billion tonnes of milk and 465 million tonnes of meat by 2050 (Steinfeld et al., 2006). To meet these demands most effort will go into intensification of improved pastures, which translates into high stocking densities supported by large inputs of fertilisers, feed supplements and energy.

This book was released on 2016-06-16 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1944, the National Research Council (NRC) has published seven editions of the Nutrient Requirements of Beef Cattle. This reference has guided nutritionists and other professionals in academia and the cattle and feed industries in developing and implementing nutritional and feeding programs for beef cattle. The cattle industry has undergone considerable changes since the seventh revised edition was published in 2000 and some of the requirements and recommendations set forth at that time are no longer relevant or appropriate. The eighth revised edition of the Nutrient Requirements of Beef Cattle builds on the previous editions. A great deal of new research has been published during the past 14 years and there is a large amount of new information for many nutrients. In addition to a thorough and current evaluation of the literature on the energy and nutrient requirements of beef in all stages of life, this volume includes new information about phosphorus and sulfur contents; a review of nutritional and feeding strategies to minimize nutrient losses in manure and reduce greenhouse gas production; a discussion of the effect of feeding on the nutritional quality and food safety of beef; new information about nutrient metabolism and utilization; new information on feed additives that alter rumen metabolism and postabsorptive metabolism; and future areas of needed research. The tables of feed ingredient composition are significantly updated. Nutrient Requirements of Beef Cattle represents a comprehensive review of the most recent information available on beef cattle nutrition and ingredient composition that will allow efficient, profitable, and environmentally conscious beef production.
