Pancosma discusses plant extracts at WCAP
The use of plant extracts in animal feed was strongly evident at the World Conference of Animal Production (WCAP) 2008 in Cape Town, South Africa from November 23 – 28. Manufacturer for plant extracts - Pancosma - presented its research on this topic.
The communications all presented by Dr. Armin Vikari, Product Manager for XTRACT Bioactives, offered a well-balanced combination of new scientific research with Eugenol, Cinnamaldehyde and Capsicum Oleoresin in beef and dairy cattle as well as new nutritional insights in the use of plant extracts in poultry.
Plant extracts for cattle
In support of a product already in use on dairy farms, a new meta analyses covering 16 trials was presented on the impact of a eugenol-cinnamaldehyde combination in dairy cow diets. Across all trials, milk yield was increased by 1.09 kg/cow/day, with corresponding uplifts in yield of protein and fat of 3.2 % and 4.3 %, respectively. Another paper identified, that supplementing an encapsulated capsicum extract increased feed intake in beef animals on a high concentrate diet by 9.9 %. At the feed rate of 0.25 g/hd/day of a product containing 20 % Capsicum Oleoresin concentrate intake was 8.4 kg/hd/day compared to 7.64 kg of a negative control.
The same trial found a 7.3 % increase in water consumption attributed to the extract, and no effect on rumen pH or ammonia level. Another WCAP paper showed that supplementing a high concentrate beef diet with 0.5g/hd/day of a 20 % Capsicum extract product increased eating time to 11.3 % from 8.0 % on a negative control. The daily depression of rumen pH was also found to be less on the trial diet.
Use in poultry diets
The results of a presented meta analyses of 13 different broiler chicken trials including 38 treatments replicates that broiler growth rate was increased by 4.9%, feed intake was 2.6 % higher, and feed conversion 2.9 % better, on diets supplemented with a combination of Carvacrol, Cinnamaldehyde and Capsicum plant extract compared to a negative control. Also, the meta analyses found parity between the extracts and positive (Avilamycin-supplemented) controls.
