The cultivation and production of industrial hemp [Cannabis sativa containing <0.3% tetrahydrocannabinol (THC)] has increased. Information regarding the nutrient composition cannabinoid concentration different plant parts are deficient. Single lots plants by-products were obtained from a licensed research station located in south-central Kansas. Samples (1) whole (no roots), (2) stalks remaining after seed harvesting, (3) unprocessed female flowers intended for extraction, (4) heads...

Forage preservation through fermentation can result in substantial DM and economic losses. The objective of this research by the use meta-analysis was to determine whether end-product measures forage parameters were capable predicting losses following ensiling. data set built searching a database for “forage,” “fermentation,” “dry matter loss.” contained 405 means from 43 peer-reviewed reports. (% original DM) ranged 0 28.6% with raw mean 6.2%. Report, biology, treatment, length, DM, pH,...

In silage corn (Zea mays L.), Fusarium graminearum causes diseases and produces the mycotoxin deoxynivalenol (DON). The work presented here investigated DON accumulation its fate during ensiling of ground, whole-plant material obtained from dual-purpose (DP) brown midrib (BMR) hybrids. Multiyear field trials arranged in a randomized complete block design were conducted Wisconsin to evaluate BMR DP hybrids response fungicide treatment. At harvest, samples chopped vacuum sealed for mini-silo...

Abstract The objective of this study was to assess the effect male-sterile versus non-sterile sorghum hybrids on nutritional value with emphasis carbohydrates. experiment conducted a dairy farm in West Texas under center pivot irrigation. Two (Non-BMR, F465; and BMR12, F430) three (non-BMR F10; F382, F431; Richardson Seeds) were used split-plot design reduce cross-pollination. Because westerly prevailing winds, allocated west east, plots blocked by irrigation section, replicated 3 times....

The study objectives were to evaluate (1) the effect of thawing unfermented whole-plant corn (WPC; Exp. 1) on fermentation capacity after several months frozen storage, and (2) temperature profile thawed high-moisture (HMC; 2) stored for a longer period then fermented at 2 ambient temperatures. Unfermented WPC HMC samples obtained from University Wisconsin–Madison Agricultural Research Station (Arlington, WI) harvest, immediately frozen, −20°C 4 or 17 mo, respectively. Both, thawed,...

The objective of this study was to evaluate the effect processor type on fermentation profile, corn silage processing score, and physically effective NDF whole-plant samples. A data set composed 3,900 samples obtained from Rock River Laboratory (Watertown, WI). All were collected 2013 2016 by Chr. Hansen team under specific protocols label as shredlage (SHRD) only if confirmed farmers or custom harvesters. total 309 3,591 labeled SHRD nonshredlage (CONV), respectively. Samples had been...

This study was done in an effort to develop a berry processing score (BPS) for sorghum silage, similar the kernel (KPS) currently used corn silage. Sorghum silage samples were collected from 3 dairies Kansas and processed Grain Science & Industry grain laboratory at State University using one of four different roll gap settings give differently samples: unprocessed, 1.5, 1.0, or 0.5 mm. After drying, placed into Ro-Tap particle separation machine 10 minutes until whole sample separated....

The objectives of this study were to develop a berry processing score (BPS) for sorghum silage, similar the kernel currently used corn and evaluate effects on starch digestibility. Sorghum silage samples collected from commercial farms in Kansas randomly assigned 1 4 levels differing roll gap spacing: unprocessed (UNP), 1.5 (1.5P), 1.0 (1.0P), or 0.5 (0.5P) mm. Differences BPS digestibility found–as decreased, both increased. Thus, by during harvest measuring extent processing, can be...

Fermented feedstuffs contain a number of volatile compounds such as organic acids, alcohols, ammonia and others that are lost in the oven dry-down process used to estimate feed dry matter.&amp;nbsp; By not accounting for these components, errors estimation moisture, caloric content crude protein will occur.&amp;nbsp;This paper addresses components major concern.

Late harvest of high-moisture corn (HMC) into late fall and winter months during 2014/2015 raised concerns among northern Wisconsin dairy farmers about fermentation frozen HMC. Although silage maintains capacity on defrosting, low temperature may inhibit fermentation. Therefore, the objective present study was to evaluate effect profile defrosted HMC stored for a longer period. An unfermented sample obtained from University – Madison Agricultural Research Station (Arlington, WI) October 2013...

Dairy cattle AA nutrition has evolved with NRC, CPM, and CNCPS model improvements. Ingredients rich in are added to dairy diets precise amounts better meet nutrient needs; however, animal health performance still varies relative expected responses when balancing for AA. The objective of this project was describe total (TAA) population statistics determine if TAA varied CP, commercial TMR. Commercial TMR, n = 141, were selected from samples submitted Rock River Laboratory further analyses....

Ground dry shelled corn is not uniform relative to animal performance. Geometric mean particle size (GMPS; μm) has been related rumen digestion but research evaluated only ground corns sized >700 μm GMPS. The industry reduced GMPS <400 in some cases. Furthermore, and standard deviation can be combined into a surface area measure (SA; cm2). objective of our work was determine if or SA were situ starch disappearance (SD; % starch) for commercial corns. Commercial dry, (n = 38) samples...

Abstract The objective of this trial was to evaluate the effectiveness using total tract neutral detergent fiber (TTNDFd) and starch digestibility methodology in formulation beef cow replacement heifer rations. This ultimately applies estimation energy availability animal accompanied performance as outlined by NASEM 2016 Nutrient Requirements Beef Cattle publication. Multiparous, Angus cows during last two months gestation yearling replacement, Shorthorn heifers comprised study. Cows...
