This study found a sex-specific programming effect on offspring growth in response to maternal spirulina intake, but high energy intake had no effect. Spirulina intake did not affect meat quality, but it may improve the ratio of polyunsaturated fatty acids/saturated fatty acids in offspring meat.
The concept of developmental programming suggests that maternal excessive energy intake during intrauterine development could permanently affect the offspring's performance. Spirulina might alleviate adverse programming effects, but currently has only been shown to affect productivity and product quality of livestock when fed directly. Therefore, we investigated effects of supplementing 20 g spirulina/day to 20 gestating and lactating sows fed either a commercial or a high energy diet (HED), on performance and meat quality of their piglets fattened for 4 months. Control and HED offspring did not differ in growth and slaughter performance. Maternal spirulina supplementation impaired growth performance in male but not in female offspring. Physicochemical meat quality was not affected by any treatment. Maternal spirulina intake tended to improve the polyunsaturated fatty acids (FA)/saturated FA ratio without affecting n-6/n-3 FA ratio in offspring meat. The present findings indicate a sex-specific programming effect for offspring growth in response to maternal spirulina but not high energy intake in pigs.
