Red tilapia study maps trade-offs in azolla-based fishmeal replacement blend

A 60-day feeding trial published in Veterinary Sciences found that replacing fishmeal in red tilapia diets with a blend of Azolla microphylla meal and soybean meal progressively reduced growth performance and worsened feed conversion as replacement rose from 25% to 75%, while fillet essential amino acid content held up through moderate levels but fell significantly at the highest inclusion rate.

Omega-3 byproduct oil could fully replace fish oil in European seabass feeds, study finds

A peer-reviewed study by researchers from the University of Porto, CIIMAR, and the University of Florence, in collaboration with EPAX®, found that fatty acid ethyl ester (FAEE) oil — a byproduct of omega-3 supplement production — can completely replace fish oil in juvenile European seabass diets without impairing growth, feed utilization, or nutrient digestibility. However, the substitution significantly reduced muscle DHA levels, pointing to a potential nutritional quality trade-off that may require mitigation.

Hemp seed inclusion at 10% of concentrate alters nutrient profile of beef, trial finds

A study published 24 September 2026 in the journal Animals reports that feeding whole hemp seeds to Holstein–Friesian bulls at a 10% concentrate inclusion rate raised zinc, magnesium, iron, retinol, and α-tocopherol in muscle tissue and improved the ratio of unsaturated to saturated fatty acids, though higher inclusion at 17% produced little additional benefit and neither level increased long-chain omega-3 PUFA concentrations.

Nestlé Purina commits €55 million to modernise Italian pet food plant for veterinary and super-premium diets

Nestlé Purina has announced a €55 million investment to modernise its Portogruaro, Italy pet food facility, coinciding with the plant's 40th anniversary. The upgrade targets super-premium and veterinary diet production capabilities, including manufacturing flexibility, digitalisation, and a new on-site wastewater treatment plant, without increasing the site's current annual output of more than 130,000 tonnes.

REAM 2026: Fishmeal shortage, export demand and low-carbon feedstocks reshape South American rendering markets

The South American rendering industry convened in Mendoza, Argentina, for the Reunion of the Americas (REAM) on 8–10 September 2026. Discussions centred on tightening fishmeal supply, surging export demand for Brazilian animal protein meals, shifting trade conditions for low-carbon feedstocks, and the growing interconnection of regional rendered-product markets.
