Introducing the 6th 2020 edition of All About Feed

In the 6th 2020 edition of All About Feed we explore the rumen microbiome. We discuss the challenges that the growing rabbit farming industry faces, and we interview animal feed expert, Jan Dijkstra, about how to reduce emissions through the proper use of feed. All About Feed also looks into feeding algae to aquaculture and algae residuals to chickens.

Swarms of locusts as chicken feed

While massive swarms of locusts are causing devastation in Africa, Asia and the Middle East, scientists in Pakistan have developed a way to turn locusts into chicken feed.

Nutritional solutions for sows under heat stress

Pigs are highly susceptible to heat stress. The efficiency of lactating sows is compromised every time environmental temperatures create a situation that is above or below particular threshold values. One of the pig’s most effective measures to reduce heat production is to reduce feed intake. We consider strategies that can help sows cope.

Boosting rabbit farming productivity and profits

Rabbit farming is expected to grow rapidly, but how will the sector reduce its impact on antimicrobial resistance?

The future global expansion of rabbit farming will be based on improved breeding selection, technological advances, and governmental support. Photo: Shutterstock

Algae residuals as chicken feed?

Belgian researchers are investigating how residual flows from algae production for human consumption can deliver value to chicken feed.

Interview: Jan Dijkstra chats about feed strategies designed to reduce emissions

Animal feed expert, Jan Dijkstra, talks about opportunities to reduce nitrogen, ammonia, phosphate and methane through the proper use of feed.

“On average, cattle farmers feed too much protein. Feed companies should assume the role of feed expert and consultant…,” says Jan Dijkstra from Wageningen University and Research. Photo: Koos Groenewold

The role of the rumen microbiome in increasing animal efficiency

In this article we discuss how just a 10% improvement in cattle efficiency could lead to a 43% increase in profits.
