“…There were also less piglets that were light-for-age and therefore at high risk of morbidity and mortality. Low body weight indicates poor productivity and higher chances of pre-weaning mortality in the piglet [1,14,15,16,17]. Therefore, based on the birth weights, BD has the potential to increase pre-weaning survival and productivity.…”

1,3-Butanediol (BD) is a ketogenic substance that can improve piglet growth and survival and potentially increase performance in gilt progeny when provided as a dietary supplement during late gestation. Gilts (n = 77; parity 1) and sows (n = 74; parities 2 and 3) were fed either a standard commercial gestation diet or a diet supplemented with 4% BD from day 90 of gestation until farrowing. Dams fed with diets supplemented with BD had higher plasma beta-hydroxybutyrate (p = 0.01) and lower non-esterified fatty acid concentrations (p < 0.001). The percentage of progeny that were light-for-age (<1.1 kg) at birth was decreased by BD (18.2 vs. 13.5%, p < 0.006), particularly in gilts (24.0 vs. 18.3%, p < 0.034). Individual birth weights and litter weights birth weights tended to be increased by the BD diet (p = 0.085 and 0.078; respectively) although these effects were not maintained to weaning. Pre-weaning mortality was greater in gilt than in sow progeny and was not altered by dietary BD. Feeding BD in late gestation can improve birth weight, but further work is needed to see if these effects are carried through subsequent stages of growth, particularly in gilt progeny.

“…Piglets weighing more than 1,600 are not considered low‐weight piglets and therefore generally do not suffer impairment on growing performance, as observed in low‐birthweight piglets (Pardo, Müller, Bérard, Kreuzer, & Bee, ). Lanferdini et al, () reported that piglets born weighing over 1,500 g do not have their performance influenced until marketed and do not have the physiological limitations and low efficiency observed in low‐birthweight piglets.…”

“…Decreased numbers of low-weight piglets are of great interest because low-birthweight piglets have significantly lower daily weight gains until weaning and during subsequent stages than do high-birthweight piglets (Beaulieu, Aalhus, Williams, & Patience, 2010;Fix et al, 2010;Lanferdini et al, 2018), who also show higher mortality rates (Hales, Moustsen, Nielsen, & Hansen, 2014) and need more time to reach market weight (Beaulieu et al, 2010;López-Vergé et al, 2018). Dietary supplementation with L-arginine may help increase the nitric oxide content in endothelial cells that line blood vessels, thus increasing the blood flow, causing vasodilatation and decreasing weight variations and the incidence of low-weight piglets (Campos et al, 2008;Madsen et al, 2017;Mateo, Wu, Moon, Carroll, & Kim, 2008).…”

The study assessed the effects of dietary L‐arginine supplementation from days 85 to 115 of gestation on sow performance, litter quality, piglet physiology and survival variables in the first 24 hr of life. Twenty multiparous sows, with a history of hyperprolificacy (more than 14 piglets per litter), were used. A completely randomized experimental design was used, consisting of two treatments: feed supplemented or not with 1% L‐arginine from days 85 to 115 of gestation. The experimental unit consisted of the sow and its respective litter, using 10 replicates per treatment. The sows were distributed into the treatments based on body condition and parity. Supplementation with L‐arginine reduced the within‐litter standard deviation and the within‐litter coefficient of variation of piglet weight at 24 hr by 54 g and 4.14 percentage points respectively (p = .029; p = .035). Supplementation with 1.0% L‐arginine decreased the percentages of piglets weighing less than 800 g by 5.60 and 5.08 points at birth and at 24 hr of life respectively. Piglets from sows supplemented with L‐arginine had higher (p = .088) average rectal temperatures at birth and lower (p = .030) rectal temperature at 24 hr of life in comparison with control piglets. No significant differences in placental weight or estimated colostrum production and intake were observed in the first 24 hr of life. At 24 hr of life, piglets weighing less than 1,000 g and from supplemented sows had lower (p = .048) surface/mass ratios and higher body mass index (p = .070). Piglets from supplemented sows and who weighed 1601 to 1,800 g had lower body mass index and ponderal index (p = .002; p = .003). Supplementation with L‐arginine during the final third of gestation reduces the incidence of unviable piglets (<800 g) and improved litter uniformity and piglets’ body conformation within the first 24 hr of life.

“…According to the Barker hypothesis or the concept of 'metabolic programming' early events, especially those occurring in the perinatal period, may permanently affect growth, body composition, and health in adult life (Barker, 1990). With the selection of hyperprolific sows in recent years, the long-lasting impacts of the inherent low birth weights were examined in several studies (Lanferdini et al, 2018). For instance, it is well documented that the reduced total number of myofibres of IUGR neonatal piglets permanently decreases their postnatal growth (Gondret et al, 2006;Rehfeldt and Kuhn, 2006;Zhang et al, 2018).…”

The Suckling and Weaned Piglet

Piglets are immature at birth, which renders them highly sensitive to environmental conditions during the neonatal period. Lean and fat tissues are important components for survival and later growth capabilities. This chapter focuses on the development of skeletal muscle and adipose tissue during intra-uterine life, suckling and post-weaning. Available data show that the profile of myosin heavy chain isoforms and the glycogen content are good descriptors of skeletal muscle maturity around birth. Expression levels of key genes such as DLK1 and IGF2, regulating the transition from proliferation to differentiation of constitutive cell precursors, could also be assessed as indicators of the relative level of maturity in adipose tissue at this period. The provision of nutrients to foetuses affects the development of muscle and adipose tissues during gestation and alters their functionalities after birth. Spontaneous intra-uterine growth restriction markedly delays the genetically programmed development of lean and fat tissues and especially impairs the formation of myofibres, thereby reducing the adaptive abilities of small neonates to the extra-uterine environment. Maternal energy or protein overfeeding have no beneficial effects on muscle development in foetal pigs, but nutritional avenues using supplementary arginine or vitamin D in sow diets at specific periods of gestation may be favourable for foetal myogenesis. The best strategies to increase body fat content before birth and enhance lipolytic and oxidation capacities of piglets soon after birth remain to be developed. During the suckling period, myofibre composition and size undergo marked changes. Adipose tissue growth is also accelerated and this is exacerbated in small littermates with detrimental effects on their physiology later in life. Supplementing the diet of suckling or post-weaned piglets with branched-chain amino acids could improve muscle maturation and affect adipose tissue metabolism. With the multiplicity of factors acting on the development of muscle and fat tissues in piglets, identifying optimal feeding strategies remains difficult.
