Feeding for Successful Offspring

Author: Cassio Villela, Sr. Swine Marketing Specialist, Novus International, Inc.

The swine industry has made great strides in swine reproduction; most specifically in the areas of increased litter size, increased milk production and improvements in productivity traits. With such rapid growth and improvement in those areas, other areas are lacking because sows’ diets haven’t all been adjusted yet to account for the nutritional and physiological demands of increased productivity.

In general, piglet birth weight has decreased and, coupled with the competition of a more-crowded udder, chances of pre-wean mortality and poor performance are more prevalent. More piglets in each litter is important for keeping up with industry demand. However, if the sow’s nutrition isn’t top notch from the very beginning, its progeny will have a harder time surviving, will likely be lighter than their contemporaries throughout life and economic losses will be greater. In addition, post-wean growth performance depends on healthy piglets, and those with extra weight will thrive more in the nursery phase and throughout the remainder of their lives.

To assure production profitability and overall health of both the sow and piglets, the low birth weight challenge must be addressed. Research has confirmed that sow mineral nutrition has the potential to enhance progeny performance, most notably in birth weight increases and post-weaning growth performance improvements.

Improving Progeny Birthweight with MMHAC

According to an experiment conducted at a commercial facility, when fed methionine analog chelated trace minerals (MMHAC) in the diet, there was a nine percent increase in piglet birth weight (Figure 1). Additionally, research shows that for every 100 grams increased in birth weight, the survival rate is increased. With MMHAC supplementation to sows, piglets are born with an advantage to resisting challenges due to their ability to be heavier and stronger.

Altering Post-Wean Performance

Weaning is a stressful period on piglets with new environmental, nutritional and social challenges. While nursery diets aim to alleviate stressors of weaning, maternal nutrition is an even more important tool to give piglets the jump-start they need to thrive and can have lasting effects on the progeny throughout all stages of life. A trial study indicated that piglets from sows fed either MMHAC or inorganic trace minerals (ITM) performed differently during post-weaning, even with the same initial bodyweight at the beginning of the trial. At 42 days post-weaning, piglets from sows fed MMHAC had 2.48 more kilograms more body weight than piglets from sows fed ITM (Figure 2).

In conclusion, supplementing MMHAC into sow or gilt diets has the potential to show lasting effects on progeny, alleviating initial challenges like pre-wean mortality and low birth weight, but it also furthers the body weight advantage in later stages of life.
