Phosphagenics Limited reported the results of its proof-of-concept study in grower/finisher pigs, assessing the potential for additional performance benefits of TPM® as a feed additive. The grower/finisher study was the second of two independent studies designed to assess the commercial value of TPM® as a feed additive in the pig production market. The first of these studies, which reported earlier 2016, demonstrated that TPM® treatment statistically improved performance in newly weaned pigs (i.e. feed conversion rate (FCR)). The recently completed second study indicated that, unlike the positive response in young pigs, older pigs treated with TPM® (at doses 5 to 30 ppm) did not demonstrate significant improvements in performance, as assessed by FCR and carcass yields. Piglets 7-14 days post weaning, experience an increase in stress combined with a decrease in the immunity bestowed by their mother. As they have not as yet fully formed their own immunity their long term development can be compromised by a number of risk factors. It is believed that treatments which benefit the piglet during this critical period can positively influence growth rate and efficiency of feed utilisation throughout the pig's entire development. The combined results from the company's studies suggest that initiating TPM® treatment in immature or newly weaned pigs may be more beneficial than initiating TPM® treatment when the pigs are older.
