Join us on the Grazing Grass Podcast as we continue our journey into the fascinating world of livestock color genetics. In this episode, we explore the practical aspects and implications for breeders, focusing on the two primary pigments—eumelanin (black) and pheomelanin (tan)—that determine livestock coat color. We simplify the terminology for ease of understanding and revisit key genetic loci, such as the extension and agouti loci, which play significant roles in coat color variations in cattle. Additionally, we discuss unique alleles like black-red, where calves change color as they age, and dominant red, which overrides the extension locus. Drawing insights from Dr. Sponenberg's "Practical Color Genetics for Livestock Breeders," we offer a comprehensive guide for beef and dairy cattle breeding.

In our discussion on cattle color dilution genetics, we shed light on the Simmental and Charolais dilution alleles, which impact coat colors, resulting in lighter shades like orange, yellow, and various grays. We also touch on other breeds such as Galloway and Dexter, which have their unique dilution genes that can sometimes lead to unexpected coat colors. Furthermore, we explore the genetic complexity in breeds like Brown Swiss and Murray Greys, and mention the recently identified Larson Blue dilution gene, enriching our understanding of the intricate genetics behind cattle coat colors.

Our exploration doesn't stop there; we also delve into the intriguing patterns of white spotting genetics in cattle. From the "wading" allele, which creates white patterns on the lower legs and belly, to the "white sides" allele characterized by animals with white sides and pigmented legs, we cover a wide range of patterns. We discuss speckled patterns such as "colorsided," "fisheagle," and "spitting cobra," along with the roan category and its variations like "marocha" and "salineiro." Finally, we examine modifiers like "brockle," "ticking," and "smudge," which add complexity to these patterns. This episode promises a rich and informative discussion on the genetic factors shaping the diverse and beautiful coat colors of livestock.

Join us for an engaging episode where we explore the transformative journey of Mike, a third-generation cattle and crop farmer from central Iowa, as he transitions from conventional farming to regenerative grazing practices. Mike candidly shares his frustrations with overgrazing and the inspiration he drew from his grandfather to adopt management-intensive rotational grazing. He takes us through the learning curve of measuring forage, setting up a daily move system, and developing a forage measurement tool. Mike’s story underscores the importance of hands-on learning and experimentation in improving farm sustainability and efficiency.

We also discuss the intricacies of rotational grazing management, emphasizing the need for accurate calibration and measurement of forage availability and livestock needs. Using tools like spreadsheets and mapping apps, we explore methods for estimating total dry matter in a paddock and determining its support duration for a herd. Mike shares personal anecdotes about managing hayfields, adjusting strategies during drought conditions, and the benefits of underutilizing grass to prevent overgrazing. The conversation highlights the role of technology in optimizing pasture rotations and the unexpected advantages of natural events.

Finally, we delve into the management of grazing and cover crops, examining the long-term impacts of reintroducing animal activity to previously inactive land. Mike shares his experiences with different cover crops and the challenges of integrating them with grazing schedules and weather events. We also touch on the unexpected outcomes of government-mandated tree planting and its implications for agricultural practices. The episode concludes with insights on cattle herd management, emphasizing the importance of both traditional education and modern resources, such as social media and online communities, in mastering regenerative grazing practices. Tune in to discover valuable resources and tools for effective grazing management and to hear practical innovations that can enhance daily farm operations.

Join us as we explore the fascinating journey of Kody, a ninth-generation agrarian from northeast Missouri, who returned to his family's farm. Kody opens up about the evolution of their farming practices, transitioning from traditional row cropping to pasture-based operations. Hear about Kody's childhood experiences on the farm, his initial reluctance towards farming due to a dislike for machinery, and how he found his way back to the agricultural lifestyle he once tried to escape. Kody's preference for livestock and grasslands is highlighted, along with the adjustments made to accommodate these preferences and the challenges and rewards of managing the family farm with his mother and grandfather.

In this episode, Kody shares insights into managing a mixed farming operation, including his passion for native grasses and habitat restoration, which he nurtured during his college years at the University of Missouri. Discover how Kody and his wife balance their roles on the farm, with his wife focusing on commercial hogs and Kody overseeing livestock, grass, and row crop aspects. Listen in as Kody discusses the introduction of rotational grazing to optimize resources, practical aspects of managing cattle and sheep, and the innovative grazing strategies they employ to ensure the health and productivity of their farm.

We also explore Kody's experiences with water management for sheep grazing, the intricacies of livestock breeding and management, and the benefits of native grass restoration. Hear about the successes and challenges Kody has faced in running a diversified farming operation, from the Lake St. Louis Farm Market to online sales. Gain valuable insights into effective grazing strategies for native grasses, and learn about Kody's favorite resources and tools for farming. This episode is a must-listen for anyone interested in regenerative grazing practices and the journey of modern agrarians.
