The addition of Origina to weaner feed had no effect on weaner productivity

A product trial of five brands of tube feeders for weaners revealed no differences in production value based on weaners’ FCR and daily gain.

The addition of 15% chicory or 7.5% chicory + 0.5% benzoic acid increased weaner productivity compared with feed with and without 7.5% chicory. No effect was found on health. With the current chicory prices, this is not profitable.

Daka Porcine Plasma had the same effect on weaner productivity as zinc. The effect of using blood plasma and zinc was additive and increased production value by 9%.

Commercial weaner diets from 5 companies purchased in South-East Jutland in the winter 2007/08 were studied. An 18% increase in production was obtained with the diets from Danish Agro compared with control.

0.6% Formi and 0.6% formic acid to weaner feed tended to improve PV by 5% compared with control.

PV dropped when inclusion of soybean meal increased. Up to 35% was gained on the bottom line by using 26-27% soybean meal in weaner feed as the feed price dropped as soybean meal inclusion increased.

The inclusion of EggsTend 88 to weaner feed did not affect productivity. 2,500 ppm zinc in the feed the first 14 d post-weaning significantly reduced diarrhoea and improved productivity.

Weaner diets were purchased from 5 different companies in the winter 2006/07. The trial revealed that the diets from ØA improved production value signigificantly compared with control as well as the other diets.

Diarrhoea treatments dropped significantly when organic acids were added to weaner feed. Mortality also dropped significantly when acid and zinc were added to the feed.

The addition of Aviprox and Aviplus til weaner feed increased the production value significantly. The increase in PV was largely outweighed by increased costs for adding the products.

Simple low-energy diets reduced productivity by 13%, but improved production economy by 18%. An alternative diet without fishmeal, but with coconut oil and dried whey reduced productivity by 7% and improved bottom line results by 7%.

C*HYPROW, hydrolysed wheat protein, in combination with potato protein concentrate may be a realistic alternative to fish meal and soy protein if the price is competitive and amino acid standards are met.

Weaner productivity in the period 0-8 wks post-weaning increased by 6% when the pigs were fed 100% fermented grain in gruel feed the first 3 wks post-weaning followed by pelleted dry feed.
