This book was released on 2015 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tall fescue (Festuca arundinacea Schreb.) is a cool season perennial grass commonly used in year-round forage production systems. Producers often wrap large round bales of tall fescue in plastic. The fermented product of this practice, termed baleage, allows the forage to be stored for later feeding. During periods of rapid growth in the spring and the fall, the nutrient content of tall fescue can be imbalanced and cause nutritional disorders in grazing animals. To improve the nutrition of tall fescue, it is known that fertilization of phosphorus (P) can help improve leaf nutrient content of P, magnesium (Mg), and calcium (Ca). Additionally, nitrogen (N) fertilization is known to improve forage quality. The objective of this study was to examine the effects of both N and P spring fertilization on tall fescue nutrient content and yield, as well as the effects of these treatments on baleage quality from these pastures. A 2014-2015 field study utilized eight different two-acre pastures, each with a P rate of 0, 25, 50, or 100 lbs P/A and a N rate of 0 or 50 lbs N/A. These studies found that N and P fertilizer did not affect yield and did not change tall fescue leaf calcium or magnesium content; however leaf P was increased with P fertilization. N treatments increased baleage protein content in the 2014-2015 study, but other quality measures were not affected by N and P treatments. The 2015-2016 field study using only P treatments and more replicates will be completed and replicated an additional year to further elucidate effects of P fertilization on tall fescue baleage.

Available in PDF, EPUB and Kindle. Book excerpt: Tall fescue is the one of most common grasses in irrigated pastures throughout the Intermountain West. Two limitations of tall fescue are a decrease in productivity during hot summer months and the need for supplemental nitrogen (N). The objective of this research was to compare tall fescue-alfalfa (TF+ALF), tall fescue-birdsfoot trefoil (TF+BFT), tall fescue-nitrogen fertilizer (TF+N), and tall fescue without nitrogen fertilizer (TF-N) on forage yield, nutritional quality, and livestock performance. Research plots were established at the Utah State University Pasture Research Facility in Lewiston, UT in 2010 and grazed in 2012 and 2013. Treatments were arranged in a randomized complete block design with four replications and divided into four paddocks per replication. Three Angus crossbred steers with an average starting weight of 380 kg were placed on each treatment and rotated to a new paddock every 7 days. A put-and-take method was used throughout the growing season such that each paddock received 80% utilization. Four forage samples were collected from each paddock just prior to grazing using a 0.5 m2 quadrat for determination of dry matter (DM) and nutrient content. ADF, NDF, IVTD, and TDN were used to estimate nutrient content and steers were weighed every 28 days to determine livestock performance. Forage yield was highest (P

Download or read book Forage Quality and Performance of Tall Fescue Hay Amended with Broiler Litter and Commercial Fertilizer written by and published by . This book was released on 2006 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Broiler chickens are a leading agricultural commodity in Tennessee. Many broiler operations are located in eastern and middle Tennessee where a common land use is tall fescue (Festuca arundinacea Schreb.) hay and pasture, for cow-calf and dairy operations. Litter from broiler operations is land applied on fescue at rates that often exceed the recommended phosphorus (P) and potassium (K) rates. Surveys of forage quality conducted by the University of Tennessee Extension in 2001 found that many forages across the state had higher than recommended K and sulfur levels and were deficient in copper (Cu) and other nutrients. In spring 2004 a two-year study initiated at the Research and Education Center at Greeneville, TN evaluated the performance and forage quality of tall fescue hay amended annually with 3 rates of broiler litter (2.3, 6.8, and 11.3 Mg/ha) and 2 commercial fertilizer rates (a recommended rate, 114-30-28 kg/ha of NPK; and a commonly used rate 65-29-54 kg/ha of NPK). The study was conducted on a Dewey silt clay loam (fine, kaolinitic, thermic, Typic Paleudult), severely eroded soil (12 to 25 percent slope). Mehlich I soil analysis indicated increased phosphorus (P) and increased zinc (Zn) levels after application and harvest. All plots were harvested in May 2004, September 2004, and May 2005. Forage analysis was conducted to determine the nutrient content in the fescue. Dry matter yields of higher quality forage were obtained using high litter rates (11.3 Mg/ha) and the recommended fertilizer rate. In 2004 and 2005, Cu, Na, and Zn levels were below and (S) sulfur levels above National Resource Council (NRC) recommendations for beef cattle, while Ca and Mg were above recommendations. Using high litter applications (11.3 Mg/ha) resulted in K levels at or above maximum tolerable concentration (30 g/kg) critical for beef cattle in May 2004 and 2005.

This book was released on 2016 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The fungal endophyte, Epichloë coenophiala Morgan-Jones and Gams, an aboveground asexual symbiont, often increases growth and stress tolerance of its host, Schedonorus arundinaceus Schreb tall fescue, a cool-season pasture grass in the U.S.E. coenophiala defends its host by producing ergot and loline alkaloids to deter mammalian and insect herbivory. The degree of mutualism between E. coenophiala and tall fescue can depend on nutrient availability, yet little is known about how nutrient addition simultaneously affects endophyte infection frequency (EIF), nutrient content, and herbivory in tall fescue. I investigated the effects of factorial combinations of added nitrogen (N), phosphorous (P), and potassium (K) on these parameters within an established field study after seven years of nutrient treatments. EIF and herbivore damage were measured on approximately 50 tillers collected from each field plot, while tissue alkaloid, N, P, and C concentrations were measures on endophyte-infected (E+) and endophyte-free (E- ) sample composites. I proposed that endophyte status would decrease herbivory, but there was no such significant effect found. I also proposed that nutrient availability would affect tall fescue's rate of tiller damage, fungal endophyte infection status, and tissue chemistry. Endophyte status effects were observed with the addition of P and with the interactive addition of P and K. Other effects on tissue chemistry and herbivory were observed as well. My results illustrate that endophyte-related benefits to tall fescue, such as enhanced fescue nutrient content and herbivore defense, depended on the fertility of the pasture within which the symbiosis occurs.

This book was released on 2010 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT:Environmental concerns over potential phosphorus (P) losses and their impacts on water quality have prompted several revisions in P fertilizer recommendations for bahiagrass (Paspalum notatum Flügge) pastures in Florida. The current University of Florida Institute of Food and Agricultural Sciences (UF/IFAS) fertilizer recommendations require both soil and tissue testing for bahiagrass pastures, but there are limited data to support the new recommendations. Greenhouse and field experiments (clipping and grazing studies) were conducted at UF/IFAS Range Cattle Research and Education Center in Ona, FL from 2006 to 2008 to evaluate the effects of the revised UF/IFAS fertilizer recommendations on forage yield, nutritive value and the potential impacts on water quality in bahiagrass pastures growing on a local Spodosol. The greenhouse study data indicated that dry matter yields (DMY) and tissue P concentration increased with P application. The critical minimum bahiagrass tissue P concentration below which DMY was impacted was 1.3 g kg-1. In the 2-yr field grazing study, bahiagrass herbage mass, herbage accumulation rates, crude protein (CP), and in vitro digestible organic matter (IVDOM) were not affected by P application. However, tissue P concentrations increased from 1.9 to 2.2 g kg-1 as P fertilization increased from 0 to 10 kg P ha-1. Mehlich-1 soil extractable P and leachate-P concentrations were not affected by P application.
