Stocker Steer Gains And Fly Numbers As Impacted By Burn Date And Type Of Mineral On Tallgrass Native Range – Year 5, Jaymelynn K. Farney, Kloey Rash, Hailey Gillespie, Emily Black, Noelle Collins

Kansas Agricultural Experiment Station Research Reports

This study aims to evaluate effectiveness of two operational management systems for steer gains and fly control. The first strategy evaluated was pasture burn date of March (MAR) or April (APR). The second management strategy was free-choice mineral with spices (SPICE) or without spices (CON). Eight pastures (n = 281 steers; initial weight 566 lb) were used in a 2 × 2 factorial treatment structure. Steers were weighed individually, randomly assigned to treatment, and grazed for 89 days. Weekly, 33% of steers were photographed to count flies and evaluated for hair coat score. Steers that grazed pastures that were burned …

Effect Of Benzoic Acid And Essential Oil Blends On Viral Load In Swine Feed And Vitamin Premix, Allison K. Blomme, Jordan T. Gebhardt, Cassandra K. Jones, Jason C. Woodworth, Elizabeth G. Poulsen Porter, Jianfa Bai, Chad B. Paulk

Kansas Agricultural Experiment Station Research Reports

Feed has been shown to harbor viable virus of interest to swine producers over an extended period of time. The use of mitigants and kill steps have been investigated with variable results. This study investigated the use of benzoic acid (BA) and an essential oil blend (EO) to mitigate the presence of porcine epidemic diarrhea virus (PEDV), porcine reproductive and respiratory syndrome virus (PRRSV), and Senecavirus A (SVA) in a complete diet (Exp. 1) and a vitamin premix (Exp. 2). Four treatments consisting of 0.5% BA; 0.5% BA and 200 ppm EO; 0.3% BA and 120 ppm EO; and 0.25% …

2019 Kansas State University Industrial Hemp Cbd Variety Trial, Jason Griffin, Michael J. Shelton, Clint Wilson, Tami Myers

Kansas Agricultural Experiment Station Research Reports

Hemp is a broad term used to describe the many varieties ofCannabissativaL. that produce less than 0.3% tetrahydrocannabinol (THC). The crop is globally significant, but only recently allowed to be grown again in the United States. Varieties have been selected and are currently grown with a wide range of cannabinoid profiles. Cannabinoids are of interest for their putative medical and therapeutic role in humans and pets. Cannabidiol (CBD) and THC are the two cannabinoids of primary interest. THC is of interest because it determines whether the final product is considered hemp (0.3% THC). CBD is of interest …

Evaluating Stocker Steer Gains On Tallgrass Native Range With Two Burn Dates And Spices In Mineral, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Objective:The overall objective of this study was to evaluate management practices that may impact stocker steer gains on a 90-day double stocking grazing system in tallgrass native range. Specific objectives include evaluating the timing of burning, addition of spices in a complete free-choice mineral, and determination if the effects are additive.

Study Description:Two pasture burning times (March or April) and free-choice mineral with or without addition of spices were evaluated using 281 head of stocker steers on eight pastures of tallgrass native range. The spices included garlic oil in powder form and Solace (Wildcat Feeds LLC). …

Spices Fed To Growing Heifers On Bromegrass Result In Increased Gains With Some Effects On Tick Populations, J. K. Farney

Kansas Agricultural Experiment Station Research Reports

Alternative methods to antibiotics/chemical usage in cattle production have been of interest in recent years and essential oils/spices have been promoted to fill this niche. The purpose of this research was to evaluate effect of feeding spices on heifer gains and as a control method for ticks. Eight bromegrass pastures were stocked (March to November) with four heifers per pasture to compare control mineral (CON) to mineral containing spices (SPICE; garlic + proprietary blend of 4 spices). Mineral (4 oz/hd/d) was blended in dried distillers grains (DDGs) and total blend was supplemented daily at 0.5% of heifer body weight. Heifers …

The Effects Of Feeding Benzoic Acid And Essential Oils On Sows And Litter Performance, M. T. Thayer, J. L. Nelssen, A. Langemeier, J. Morton, Z. Ou, J. R. Bergstrom

Kansas Agricultural Experiment Station Research Reports

A total of 48 sows (DNA Line 200 × 400) and their progeny were used in this study to determine if feeding sows and/or piglets benzoic acid (VevoVitall, DSM Nutritional Products, Parsippany, NJ) paired with an essential oil blend (CRINA, DSM Nutritional Products, Parsippany, NJ) enhances sow and pig performance during lactation, piglet weight gain in the nursery, and survivability to market. For sow and preweaned piglet performance in the farrowing house, adding benzoic acid and an essential oil blend to the maternal diet did not affect (P>0.05) litter performance or weaning weight of the piglets. Fecal swabbing litters …

Kansas Agricultural Experiment Station Research Reports

A total of 1,260 pigs (PIC 327 × 1050, initially 48.7 lb) were used in a 125-d trial to determine the effect of two dietary essential oil mixtures on the growth performance, carcass characteristics, and economics of finishing pigs. Pigs were allotted by BW and randomly assigned to 1 of 5 dietary treatments. Pigs were fed six dietary phases. Treatment 1 was the control with no feed additives and 12% of CP in the Phase 6 diet. Treatment 2 was the same formulation as treatment 1 but contained an essential oil mixture 1 (EOM 1) containing caraway, garlic, thyme, and …
