Interpretive Summary: Effect of sex and milk replacer with or without supplemental carnitine and arginine on growth characteristics, carcass, and meat quality of artificially reared low-birth weight pigs

Breeding efforts to increase litter size in modern sows have inadvertently reduced the average birth weight of piglets, resulting in a higher number of piglets born with low-birth weight. These piglets are indeed vulnerable from birth and display relatively poor growth potential from a very early stage. For this reason, artificial rearing strategies are potentially a management option to improve the growth of these runt piglets. With an artificial rearing system, it is possible to provide specialized diets already during the suckling period, with inclusion of specific nutrients in certain concentrations suggested to improve the growth of runt piglets. Using an artificial rearing system allows for the provision of specialized diets during the suckling phase, which includes specific nutrients aimed at enhancing the growth of underdeveloped piglets. However, in the current experiment, the particular nutrients and their dosages did not significantly improve growth or other characteristics compared to the control group.
