Annual forage crops can provide short-term grazing between crop rotations or be interseeded into perennial pastures to increase quality and productivity. They also an opportunity the economic environmental sustainability of systems. Cool-season annual high-quality, abundant biomass when availability from species is lacking, reducing need for stored feeds during winter months. For example, ADG 1.5 kg have been reported using small grains alone in mixtures with ryegrass (Lolium multiflorum...

Brassica plants play an important role in common agricultural practices, such as livestock feed or biofumigation, due to the bioactivity of natural degradation products glucosinolate metabolites. Therefore, ability survey comprehensive profiles for individual brassicas is essential informing proper species selection intended application. Current methods identification and quantification involve complex unconventional procedures, reference materials are not readily available. researchers with...

Core Ideas The accuracy of rising plate meter in multispecies swards has not been tested thoroughly. Forcing X intercept to zero increases the precision calibration equations. Higher‐order polynomial regressions do result more accurate forage estimates. (RPM) provides rapid estimates herbage mass (HM). Accurate RPM is difficult due variability management, growth, and species composition. typically calibrated by linear regression HM height; however, r 2 usually low. Curvilinear regression,...

Beef calf management strategies used during the weaning and postweaning period can have extended effects on growth performance health in production chain. With number of different practices beef cow-calf operators use these stages production, it is important for Extension educators to understand which are most commonly where educational gaps might exist. The objective this study was determine farmer perceptions, on-farm applications, potential barriers adopting backgrounding among Alabama...

Dual-purpose wheat (Triticum aestivum L.) systems are commonly used in the Great Plains of United States but not often Southeast. This study aimed to evaluate viability dual-purpose management Wheat varieties evaluated were generic feed type (unknown variety blend, Feed), seed GA Gore (Seed), and 2 forage types, AGS 2024 (AGS) Pioneer 26R41 (Pioneer). The experiment was a randomized complete block design (n = 4) conducted during winters 2021 2022. Three grazing frequencies used: an ungrazed...

Diets were randomly assigned fermentors a 4 × Latin square design using 7 d for adaptation 3 collection. were: 1) 50% + (ARG); 2) (CAN); 3) (RAP); 4) (TUR). Feedings (82 g DM/d) occurred four times daily...

ABSTRACT A 3-yr grazing experiment was conducted to quantify productivity, quality characteristics, and beef performance from wheat (Triticum aestivum) triticale (× Triticosecale) forage compared with ryegrass (Lolium multiflorum) for use in the Gulf Coast region. Six 1.42-ha pastures (2 paddocks/forage treatment) were seeded early fall of each year stocked continuously beginning late winter 3 yearling steers (322 ± 10 kg initial BW). Additional put-and-take used maintain available mass at...

ABSTRACT Tall fescue ( Lolium arundinaceum [Schreb.] Darbysh.) is one of the most widely grown grasses in United States. Most plants are infected with an endophyte, Epichloë coenophiala Bacon and Schardl. This endophyte produces high concentrations ergot alkaloids, which cause toxicosis livestock. The economic losses to US livestock industry estimated be approximately $1 billion annually. objectives were evaluate variability total alkaloid ([TEA]) ergovaline ([E]) leaf blades sheaths, whole...

ABSTRACT Information regarding the susceptibility of currently grown bermudagrass [ Cynodon dactylon (L.) Pers.] cultivars to stem maggot (BSM; Atherigona reversura ) could aid forage producers with implementation integrated pest management (IPM) strategies manage this exotic pest. The objectives research were compare severity damage among selected and quantify phenotypic variation in cultivar response BSM cultivars. Eight used study. Flies collected from infested fields introduced six times...

Condensed tannins (CT) have been observed to reduce enteric CH4 production when added ruminant diets. However, high concentrations of CT in forages such as sericea lespedeza (SL; Lespedeza cuneata (Dum. Cours.) G. Don) may depress nutrient digestibility. Oilseed crops, lipid concentration, also via toxicity methanogenic bacteria with less depression it is unclear whether combining these two feeds would result even greater decreases without impairing ruminal fermentation. This study used an...

A two-year study was conducted in bermudagrass hay fields central Alabama to estimate the potential of plant growth-promoting rhizobacteria (PGPR) as a tool for sustainable agriculture forage management. This compared effects two treatments PGPR, applied with and without lowered rates nitrogen, full rate nitrogen fertilizer production system. The PGPR included single-strain treatment Paenibacillus riograndensis (DH44), blend including Bacillus pumilus strains (AP7 AP18) strain sphaericus...

Abstract A 4‐unit, single‐flow continuous culture fermenter system was developed to assess in vitro nutrient digestibility, volatile fatty acid (VFA) concentration and daily enteric methane (CH 4 ) production of ruminant diets. The objective develop a closed‐vessel that maintained protozoal populations provided accurate predictions total CH production. diet 50% orchardgrass ( Dactylis glomerata L.) alfalfa Medicago sativa fed during 4, 10‐day periods (7‐day adaptation 3‐day collection)....

Abstract Creating ensiled forage on a laboratory-scale is tedious and cumbersome process. One must ensure an anaerobic environment for the success of fermentation while also striving to replicate field-scale conditions. The objective this experiment was determine effect silo type nutritive value profiles grass-legume silage. This conducted as generalized complete block design. There one treatment factor (silo type) with 11 levels: baleage control (CON), miniature wrapped (MINI), large bucket...

Abstract Grazing cool-season cover crops provides a sustainable way of extending the grazing season and reducing impact row-crop farming systems on environment. Cover promote soil health; however, impacts health in Southeast are not well understood. The objective current study was to determine effects different crop mixtures cotton (Gossypium hirsutum)-peanut (Arachis hypogaea) cropping system. experiment consisted 18 paddocks, planted grass [‘Coker’ oat (Avena sativa)], + legume [‘Dixie’...

Abstract In the Deep South, one of hardest times year for cattle producers is summer due to extreme temperatures and low-quality perennial forages. Incorporating a high-quality crop like alfalfa (Medicago sativa) into forage mixtures could be economically advantageous; however, there not much produced in South. Therefore, our objective was evaluate effects type on vivo digestibility nutrient balance beef systems. There also an interest differing conserved types, so we analyzed digestion...

Abstract Though much effort has been made to characterize the in vivo (IV) and situ (IS) dry matter digestibility (DMD) of southeastern forages, there is a lack information identifying methods that best represent these forages. Thus, objective our study was compare IV IS determine which technique represents DMD four bermudagrass (Cynodon dactylon [L.] Pers.) cultivars. In an experiment, ruminally fistulated heifers (n = 4) were randomly assigned one cultivars (Coastal [COS], Russell [RUS],...

Abstract Pastures in Tennessee comprise mainly tall fescue [Schedonorus arundinaceus (Schreb.) Dumort.], a cool-season perennial grass. Given that producers feed hay for an average of 143 d per year, there is interest utilizing the practice stockpiling to extend grazing season. Although this has been proven reduce needs (Freeman et al., 2019), it vital maintain up-to-date recommendations using data from across southeastern US inform decisions. The objective study was determine nutritive...

Abstract Sustainability is a ‘buzzword’ often used within and outside of the agriculture industry. Southeastern beef cow-calf stocker operations utilize management practices which embody core definition sustainability to improve land resource, economic, social viability. In forage-based production systems, year-round are generally viewed by scientific community in terms economic responses. However, continual global shift emphasis on sustainable creates an opportunity view these through...
