The weight gain results are presented in Figure 9, where it can be seen that the
growth rate for the piglets fed diets 1 and 3 were comparable to each other, while the
growth rate for the piglets fed diet 2 was less. สอง key findings are made: first, the 10 weight gain of the piglets on the optimised essential amino acid diet (diet 3) was
comparable to the piglets on the control infant สูตรof diet 1, and in this regard it is
noted that the protein levels of the สอง diets were significantly different; and second,
the weight gain of the piglets on the optimised essential amino acid diet (diet 3) was
greater compared to the piglets on the control infant สูตรof diet 2, and it is noted 15 that the protein levels of the สอง diets were the same.
It should also be noted that the อัตราส่วนของอะมิโนแอซิดจำเป็น to non-essential
อะมิโนแอซิด in diet 3 was approximately 50:50 which is similar to that in diets 1 and 2,
and also in line with the typical อัตราส่วนของอะมิโนแอซิดจำเป็น in human breast milk and สูตรที่มีซื้อขายในเชิงพาณิชย์s. Therefore, it is emphasised that diet 3 did not simply involve a lowering of the total essential amino acid levels relative to the non-essential amino acid levels in order to reduce the total level of protein.
5 These results therefore suggest that the new optimised essential amino acid
composition allows for greater weight gain compared with a composition containing the same amount of total protein and a non-adjusted essential amino acid composition. The results also suggest that the new optimised essential amino acid composition
allows for similar weight gain compared with a composition containing a higher
10 amount of total protein and a non-adjusted essential amino acid composition.
Furthermore, these findings cannot be explained by a relative increase or the อะมิโนแอซิดจำเป็น (because the อัตราส่วนของอะมิโนแอซิดจำเป็น to อะมิโนแอซิดไม่จำเป็น in all สาม diets was approximately 50:50) but by a change in the อัตราส่วนของall อะมิโนแอซิดจำเป็น.
15 Furthermore, the organ development in the piglets of this study was investigated.
No adverse developmental effects were detected in the piglets on the optimised
essential amino acid diet (diet 3) relative to the control infant สูตร (diet 1). This suggests that 20% reduction of the protein load with an optimised amino acid
composition does not induce any acute growth deficits or disproportional growth
20 effects in the piglets.
As such, using the new optimised amino acid composition may allow for effective lowering of protein levels in infant formula.
