Effects of Moringa oleifera leaf meal on plasma ghrelin and insulin-like growth factor-1 levels in swine and its potential role in improving sow productivity

Abstract

Two experiments were conducted to determine the possible role of Moringa oleifera on sow productivity and ghrelin-growth hormone (GH)/insulin-like growth factor-1 (IGF-1) metabolic pathway. in the first experiment, the effects of 15% M. oleifera leaf meal (MoLM) inclusion in the diet on the plasma ghrelin and IGF-1 levels were determined using four sexually mature gilts with indwelling catheter. Results showed that plasma ghrelin and IGF-1 levels between the control and experimental groups were not statistically different, although pigs fed with MoLM had apparently lower baseline and higher amplitude of plasma ghrelin levels particularly a few hours right after feeding time. on the other hand, IGF-1 level in pigs fed with MoLM seemed down regulated. the second experiment aimed to know the effects of supplementing 15% MoLM on body condition and sow productivity during the week of gradual feed withdrawal prior to farrowing. A total of 16 sows with 141 piglets were used. Although the experimental group registered higher values, the difference in backfat losses from the control group is not statistically significant. The same results were observed for the corresponding piglets; despite higher weaning weight and average daily gain, the control group was not statistically different from the experimental group. the results showed the potential of 15% MoLM in improving sow productivity through ghrelin – GH/IGF-1 metabolic pathway. Further studies are recommended with longer duration of supplementation. These are also recommended to isolate the potential component in MoLM that improves milk production because the high fiber in MoLM possibly contradicts ghrelin release in the stomach.
