US: first application for using hemp as feed for poultry
The first submission for hemp to become an approved animal feed ingredient in the US has been put forward for consideration by the As- sociation of American Feed Control Officials and the US Food and Drug Association – Center for Veterinary Medicine (FDA-CVM). Led by the Hemp Feed Coalition leadership, hemp and feed industry experts, and researchers, this submission is a culmination of a two-year ingredient investigation of hemp seed cake and meal and a clinical trial to demonstrate the safety and efficacy of hemp for laying hens. Hemp seed cake and meal has a compo- sition of, on average, about 30% protein, 10% fat and a range of carbohydrates. “For the Hemp Feed Coalition, our goal is to find a use for the highly nutritious by-products of hemp production and processing,” says Hunter Buff- ington, Executive Director of the Hemp Feed Coalition. “Like most agriculture commodities, these products have value as ingredients in human and animal food markets and we are working to add this tool to the hemp farmers’

toolbox to stabilise the supply chain, create new markets and help farmers access addition- al streams of revenue for their farm products.” To meet the FDA-CVM standards of safety and efficacy, the hemp industry shared Certificates of Analysis from across the US to demonstrate that hemp seed cake and meal can be consist- ently grown and processed. This effort was combined with expertise from hemp and feed industry leaders, researchers, and the support of IND HEMP to submit the research to the FDA-CVM for scientific review.
We’re pleased to announce the new website for All About Feed live. The new design features a refreshed look and improved navigation, making the website more user-friendly, provid- ing our readers with an easy way to stay up-to- date on the latest developments in animal nutrition. This new All About Feed website in- cludes a number of updated focus sections on relevant topics in the feed industry, such as mycotoxins and new proteins, plus digital tools and in-depth information.We have also estab- lished a market portal, where you can find the latest prices and developments for wheat, maize and soy and have access to real-time pricing of feed additives. We hope that you en- joy the fresh look and feel of our updated web- site. Your feedback is always welcome.
New feed additive reduces dairy cows’ methane emissions
A novel feed additive that can be included in the diet of dairy cows has been shown to sig- nificantly reduce methane emissions by up to 40%. A trial was conducted at the dairy inno- vation centre’s Dairy Campus of Wageningen Livestock Research in Leeuwarden, the Nether- lands, to investigate the effect of supplemen- tation with Royal DSM’s methane inhibitor, Bovaer, in different diets. A total of 64 Holstein- Friesian cows in mid-lactation were involved in the study, which was designed to determine the effect of dietary composition (three differ- ent ratios of grass silage and maize silage in di- etary roughage, covering most of the feed one would encounter on Dutch farms) on the de- gree of methane reduction with two different dosages of Bovaer.
Emission reduction from 27-40% Emission reduction varied from 27% to 40% of methane per kg of feed dry matter consumed, depending on the composition of the diet as well as the dosage of the supplement.

According to the scientists leading this study, Sanne van Gastelen and André Bannink, the results are promising and appear consistent, confirming expectations that reduction de- pends on dosage and the type of diet fed. Methane was reduced by: - 27%: when a low dose of Bovaer (60 mg/kg dry matter) was added to a diet without maize silage in the roughage, - up to 35%: when a low dose of Bovaer was added to a diet containing 80% maize silage in terms of roughage dry matter intake. With a medium dose of Bovaer (80 mg/kg dry matter), these percentages ranged between 29 and 40%.
Just a quarter teaspoon a day is effective Bovaer can be used as a feed additive for cows as well as other ruminants, such as sheep and goats. Only a quarter teaspoon of Bovaer per cow per day suppresses the enzyme involved in the last step in the methane-forming

pathway of rumen archaea (i.e., methane pro- ducers in the cow’s rumen), without effecting the rumen micro-organisms which do not pos- sess this enzyme. Bovaer takes effect immedi- ately and is broken down in the cow’s normal digestive system into compounds which are al- ready present in the cow’s feed and digestive system and hence are natural. DSM has regis- tered the product in various parts of the world and it is expected that registration will be complete in Europe towards the end of 2021.
