A Letter from the Vice President of Nutrition at Agrarian Solutions® After feeding a challenging 2022 corn silage crop and corn by-products, the industry was looking forward to a lower mycotoxin-contaminated feed inventory in Fall 2023. Early corn silage and corn grain assays suggest some areas in the US will have cleaner feeds for the next year, while the challenges will continue for other regions.

The following data tables and maps report the mycotoxin assay results from April 1, 2023 through Sept 30, 2023, and admittedly are a mix of 2022 feeds and 2023-harvested feed ingredients. My personal review of numerous mycotoxin assays across the US indicates that 2023 feeds will be a repeat of 2022.

Agrarian Solutions is making a major effort to identify crop year on as many feedstuff assays as possible to clarify year-to-year trends. Let me encourage you to participate by noting crop year on your sample submission forms when such information is available.

The recently released DTX Concentrate study confirms 25 years of field experience for the product providing effective mycotoxin protection. The research results will be presented at upcoming scientific meetings and published in a peer-reviewed journal. Please contact your local Agrarian representative or myself for a personal review of the study and its implications for your clients.

Agrarian Solutions greatly appreciates your support and we will soon be introducing new collaborative efforts to strengthen the success of you and your clients.

Looking forward to the future, Larry Roth, Ph.D., PAS Vice President of Nutrition Agrarian Solutions

Supplementing Select DTX™ to Early-Lactation Holstein Cows Challenged by Mycotoxins Improves Milk Production Previous research studies have documented the reduced milk production associated with feeding mycotoxin-contaminated diets. Recent research indicates that commonly used mycotoxin protection products are often more effective for binding nutrients than the targeted mycotoxins. In farm conditions for 25 years, dairy professionals have cited the ability of the unique Select DTX product to support milk production when cows are challenged by mycotoxins. This study was conducted at a large, high-performing Holstein herd to demonstrate the benefits of DTX when lactating dairy cows are challenged by DON and zearalenone¹.

PROCEDURES The study was conducted as a randomized controlled trial from August 29, 2022 to May 28, 2023, in New York, at a 3,600-cow commercial dairy farm experienced in conducting commercial feed additive research. After entering the dry pen, Holstein cows were blocked by lactation group, expected calving date and stratified by lactation (1st, 2nd, 3rd+), and then randomized to either a control group (base ration without DTX; control) or a treatment group (base ration with DTX; DTX). The study was conducted with a control premix (no DTX) or a DTX premix (providing a minimum of 9 g DTX/cow/d to the lowest DMI pen (1st lactation, 50 lb DMI/d) with an average DTX intake of 10.34 g/cow/d.

Daily feed mixing, delivery time, weight and daily refusals per pen were according to the Dairy’s standard feed mixing protocol and recorded using FeedWatch®. Dry matter intake (DMI) was statistically analyzed for the entire 40-week study even though the trial pens were not full of randomized cows. Samples of each pen’s TMR were obtained initially twice per month and then monthly for mycotoxin analyses (Actlabs).

The cows were milked in accordance with the dairy’s standard milking routine (3X/d) and daily individual milk weights were recorded using the Afimilk® system. Milk components and quality were evaluated by twice weekly pen level string samples using the QualiTru® sampling system and analyzed by Dairy One Lab. Reproduction protocols and results are reported in an accompanying technical report.

Statistical analysis was conducted with individual cows as the experimental units for daily milk production, and pen was the experimental unit for measurements such as dry matter intake (DMI), weekly milk components and quality. Continuous variables were analyzed for treatment effect with mixed linear regression models allowing for repeated measurements as needed.

RESULTS AND DISCUSSION The description of cows by lactation and research group utilized in the study are listed in Table 1.

Supplementing Select DTX™ to Early-lactation Holstein Cows Challenged by Mycotoxins Improves Pregnancy Rate Feeding mycotoxin-contaminated diets to early-lactation dairy cows often impairs reproductive success. Dairy producers and nutritionists have been supplementing the Select DTX product to lactating dairy cows and observing improved pregnancy rates for over 25 years. This study was conducted at a large, high-performing Holstein herd to demonstrate the reproductive benefits of feeding DTX to early-lactation dairy cows when challenged by deoxynivalenol- (DON) and zearalenone-contaminated diets¹.

PROCEDURES The study was conducted as a randomized controlled trial from August 29, 2022 to May 28, 2023, in New York, at a 3,600-cow commercial dairy farm experienced in conducting commercial feed additive research. After entering the dry pen, Holstein cows were blocked by lactation group, expected calving date and stratified by lactation (1st, 2nd, 3rd+), and then randomized to research groups with dietary treatments beginning at calving. Depending upon the research group assignment, upon freshening the cows entered either a control group (base ration without DTX; control; 463 cows) or a treatment group (base ration with DTX; DTX; 463 cows). The study was conducted with a control premix (no DTX) or a DTX premix (providing a minimum of 9 g DTX/cow/d to the lowest DMI pen (1st lactation. 50 lb DMI/d) with an average DTX intake of 10.34 g/cow/d for all cows.

Feeding practices and recording, as well as milking procedures and measurements are reported in a separate technical report. Samples of each pen’s TMR were obtained initially twice per month and then monthly for mycotoxin analyses (ActLabs).

A standard presynch-ovsynch program was utilized to synchronize cows for first service at 73+3 DIM . Approximately 90% of 1st-lactation and 99% of 2nd- and 3rd-lactation cows received an embryo at first breeding, with the remainder being of exceptional genetic value and being serviced by artificial insemination (AI). All 4th- and greater-lactation cows were serviced with conventional beef semen. The initial pregnancy diagnosis was at 28-34 d post-service and final pregnancy determination at 61-67 d post-service. Records of breeding method, date, technician, as well as date and outcome of pregnancy diagnosis were recorded in DC305.

Statistical analysis was conducted with individual cows as the experimental units. Pregnancy outcomes were analyzed with mixed linear regression models with terms for treatment, lactation number, breeding method and the interactions.

RESULTS AND DISCUSSION The description of cows by lactation and research group utilized in the study are listed in Table 1.

The TMR contamination levels of DON (Figure 1) and zearalenone (Zea) (Figure 2) recorded throughout the study did not differ between the research groups for DON (P=0.60) (1,572 ppb and 1,560 ppb for control and DTX, respectively) or Zea (P=0.08)(150 ppb and 143 ppb for control and DTX, respectively).

Mycotoxin Summary Results Mycotoxin evaluation is a key component of the Agrarian Mycotoxin Protection Program. The mycotoxin summary results for April 1 through September 30, 2023 are displayed in figures 1 and 2. These values reflect a combination of preserved 2022 feeds and newly harvested 2023 corn silage. For corn silage and dairy TMR samples, respectively. Mycotoxin assay results vary considerably across the United States. The past trend is for mycotoxin levels to increase as we move from the Plains States east to PA and NY, and there is not a clear pattern of 2022 vs 2023 values.

The states of OH, NY and PA reported elevated DON, zearalenone and fumonisin levels for an unfortunate trifecta. The IL fumonisin TMR levels were surprisingly high given the moderate levels of the corn silage, which suggests the feeding of contaminated by-products.

I encourage you to participate in the Agrarian mycotoxin testing program. We are emphasizing recording crop for the corn silage samples to identify year to year changes, as well as variability through the year. In addition, please consider the value of monthly monitoring of TMR and corn silage for mycotoxin variation. Proactive sampling may help to identify challenges before escalating. Contact your Agrarian representative for the latest on mycotoxin evaluation.
