Australian company formed to commercialize seaweed additive
Australia's Commonwealth Scientific & Industrial Research Organization (CSIRO) has announced the formation of a new company to take a methane-busting seaweed to market, with $13 million (Australian) secured from five investors.

FutureFeed Pty. Ltd. will commercialize a livestock feed additive made from the seaweed Asparagopsis, which has been shown to reduce methane emissions in beef and dairy cattle by more than 80% in research trials in Australia and the U.S., CSIRO said.

Crossbreeding of Holstein cows improves fertility
without detriment to milk production

Research in the Journal of Dairy Science® examines generational effects of crossbreeding

Since 1960, Holstein dairy cows have exhibited a substantial decline in fertility, with serious economic consequences for farmers. Genetic selection programs in the United States and elsewhere have emphasized milk production at the expense of other traits. Attention has turned to improving these neglected traits for better overall well-being of cows and to ameliorate dairy producers’ profitability. In a recent article appearing in the Journal of Dairy Science, scientists from the University of Minnesota examined the effects of crossbreeding on fertility and milk production across three generations in a large sample of Holstein and crossbred cows.

Although in recent years Holstein breeding programs have made strides toward remedying the problem of diminished fertility, crossbreeding is often seen as a possible means to achieve greater and more rapid gains, while eliminating concerns about inbreeding.

“A larger response in phenotypic fertility will be experienced over a shorter period of time from crossbreeding than from selection within a pure Holstein population,” explained lead author Amy Hazel, PhD, University of Minnesota, St. Paul, MN, USA. Whether this is true, and whether crossbred cows can compete with Holsteins in a high-producing commercial dairy setting, were questions that the team investigated.

Purebred Holsteins were compared with cows from a three-breed rotation of Holstein with Viking Red and Montbéliarde in this 10-year study with initial enrollment of 3,550 Holstein cows from Minnesota commercial dairies. The team found that each combination of two- and three-breed crossbred cows demonstrated significant advantages over pure Holsteins for all fertility traits at each studied lactation. This confirmed expectations, but what about the possibility that milk production might be negatively affected by crossbreeding? “Because of the global predominance of high-producing Holsteins, some dairy producers have been concerned that crossbred cows will have poorer milk production traits,” observed Prof. Hazel. “But our study found little, if any, loss of fat and protein production for crossbred cows compared with their Holstein herdmates.”

As dairy producers place increased emphasis on minimizing the major expenses for cows—including feed intake, repeated inseminations, health treatments, and premature replacement—this large and carefully designed study confirms that strategic crossbreeding can improve fertility of dairy herds, reduce costs of insemination, and result in more efficient milk production, without significant losses in milk composition. Additionally, a larger effect should be the longer herd life of crossbred cows compared with pure Holsteins. Although further research remains to be performed, this study establishes the Viking Red and Montbéliarde breeds as highly complementary for crossbreeding with Holsteins and well suited for milk production in high-performance dairy herds.

Have you registered for the 39th ADSA Discover Conference? It's a Virtual Event

The 39th American Dairy Science Association® (ADSA) Discover Conference: The Transition Period – From Physiology to Management, planned for October 26-29, 2020 and originally scheduled to occur in Itasca, IL will move completely online.

ADSA’s Discover Conferences TM have been designed to offer an informal environment and format that encourages candid interactions among scientists to improve learning and understanding of timely topics in the science of food animal agriculture. The interactive spirit of Discover conferences will remain in the virtual format; with structured discussions woven into the program, including focused discussions with the speakers. As is consistent with previous Discover Conferences, registration will be limited in order to maintain the small group, quality discussions that participants have come to appreciate about attending a Discover Conference.

This conference will highlight scientific advancements made in the last 10 years relative to the Transition Period. Conference topics include: Physiology, Inflammation and Immune Function, Management and Feeding, Monitoring and Analysis, and Health.

“Moving to a virtual event allows us to connect with colleagues near and far in a meaningful way; while encouraging dialogue and collaboration on advancements in dairy science,” said Catharine Perry, Executive Director of the American Dairy Science Association.

NASEM Nutrient Requirements
of Dairy Cattle
June 1-4, 2021
Eaglewood Resort & Spa

The National Academies of Sciences, Engineering, and Medicine (NASEM, previously known as NRC) anticipates the 2021 release the 8th revised edition of the “Nutrient Requirements of Dairy Cattle”, the world’s most highly cited reference on dairy cattle feeding.

This 40th Discover Conference will focus on the scientific advancements in dairy cattle feeding used in revising the 2001 edition. NASEM subcommittee members will address the substantive changes in the nutrient requirements and the conceptual approaches used to make those changes. They will report on areas with significant knowledge gaps that still prevent more accurate prediction of the nutrient requirements. We will emphasize the interactive spirit of Discover conferences with structured small group discussions woven into the program, including a demonstration of the software and focused discussions with the speakers. The program will bridge from the fundamental science to applied dairy cattle feeding:

Conference Topics Include:
·      Feed Intake, Fats, Carbohydrates and Energy
·      Proteins and Amino Acids
·      Minerals, Vitamins and Water
·      Dry Cows, Calves and Replacement Heifers
·      Application of the New Requirements

Registration postmarked by April 30, 2021, is $375 for ADSA-ARPAS members and $425 for non-members, which includes sessions and most meals. After April 30, the registration fee will be $475 member/$525 non-member. Registration will be accepted on an availability basis. Your registration includes 90 days free access to the Searchable Proceedings of Animal Conferences (S-PAC)..
