“…Variation in this trait can considerably affect an animal's subsequent growth and development, with consequences for survival and reproduction (Albon, Clutton-Brock, & Guinness, 1987;Lindström, 1999;Quiniou, Dagorn, & Gaudré, 2002). Typically, offspring born with smaller size and with a lower postnatal growth often suffer from a higher mortality prior to weaning and beyond (Côté & Festa-Bianchet, 2001;Guinness, Clutton-Brock, & Albon, 1978;Magnabosco, Bernardi, Went, Cunha, & Bortolozzo, 2016;Maniscalco, 2014;Rödel et al, 2015;Rödel, Starkloff, Seltmann, Prager, & von Holst, 2009). …”

We asked whether within-litter differences in early body mass are associated with differences in house mouse pups' thermogenic performance and whether such variation predicts individual differences in competitive interactions for thermally more advantageous positions in the huddle. We explored pups' thermogenic performance in isolation by measuring changes in (maximal) peripheral body temperatures during a 5-min thermal challenge using infrared thermography. Changes in peripheral body temperature were significantly explained by individual differences in body mass within a litter; relatively lighter individuals showed an overall quicker temperature decrease leading to lower body temperatures toward the end of the thermal challenge compared to heavier littermates. Within the litter huddle, relatively lighter pups with a lower thermogenic performance showed consistently more rooting and climbing behavior, apparently to reach the thermally advantageous center of the huddle. This suggests that within-litter variation in starting body mass affects the pups' thermal and behavioral responses to environmental challenges.

“…Therefore, lower numbers of primordial, pre-antral and medium size (3-5 mm) follicles, associated with higher number of atretic follicles and shorter vaginal length, suggest lower ovulation rate and consequently smaller litter size in LW females. Further evidence of the negative impact of low birthweight on piglet production and sow longevity was recently shown in the study of Magnabosco, Bernardi, Wentz, Cunha, and Bortolozzo (2016), where females born with less than 1 kg birthweight produced approximately 4.5 fewer piglets over three parities, with an average of 1.6 fewer piglets than the mean of the heavier birthweight classes in the first farrowing.…”

In the last decades, selection for improved prolificacy has resulted in higher litter sizes and has thereby increased the proportion of low birthweight (LW) piglets. It is well documented that LW piglets have lower growth performance, muscle accretion and poor carcass quality. However, little is known about the relations of birthweight with subsequent reproductive performance in gilts. This study investigated the effects of birthweight on reproductive tract and ovarian follicle development in 150-day-old gilts. Twenty eight female pigs of different birthweight ranges (high-HW: 1.8-2.2 kg; low-LW: 0.8-1.2 kg) from higher parity commercial sows were reared until 150 days of age, and their body weights were recorded at weaning, end of nursery and end of the grower-finisher phase. The animals were killed and their reproductive tracts collected for biometrical and histomorphometrical analysis. LW gilts showed significantly lower body weights and growth rates during all phases of production compared to their HW counterparts (p < .01). Most biometrical measurements of the reproductive tract were similar between the experimental groups, except vaginal length and the gonadossomatic index (relative ovarian weight), which were affected by birthweight class (p < .05). LW females also showed fewer medium size (3-5 mm; p < .01) ovarian follicles, pre-antral follicles (p < .07) and more atretic follicles per ovarian cortex area (p < .05). Therefore, besides the effects on post-natal growth performance, birthweight affects vaginal length and the follicular dynamics process, which may impair the reproductive performance of replacement gilts.

“…However, as the number of piglets born has increased, the birth weight has decreased due to a greater competition for nutrients in the intrauterine environment (Town et al, 2005;Foxcroft et al, 2006). Low-birthweight piglets have several negative implications during their lifetime, such as greater pre-weaning mortality (Quiniou et al, 2002), greater mortality during nursery period when associated with a reduced colostrum intake (Ferrari et al, 2014), reduced weaning weight and subsequent market weight (Quiniou et al, 2002;Fix et al, 2010;Alvarenga et al, 2012), and decreased reproductive performance (Magnabosco et al, 2016).…”

The effects of increasing feed intake (1.8, 2.3, 2.8, and 3.3 kg/d) during late gestation of gilts on piglet birth weight and female reproductive performance were evaluated. A total of 977 gilts were fed a diet based on corn-soybean meal (3.29 Mcal ME per kg and 0.64% standardized ileal digestible lysine) from day 90 of gestation until farrowing. Gilts were weighed on days 90 and 112 of gestation, at farrowing and weaning. Born alive and stillborn piglets were weighed within 12 h of birth. Colostrum yield (CY), lactation feed intake, and litter growth rate were measured in a randomly selected subsample of 245 gilts. The data were analyzed using generalized linear mixed models. As expected, gains in body weight (BW) were different at day 112 (P < 0.001) with the greatest values observed in the 3.3 kg/d treatment. As feed intake increased during late gestation, BW, body condition score (BCS), backfat (BF), and Caliper unit also increased between day 112 and weaning (P < 0.001). No differences were found among treatments in total number of piglets born, mummified fetuses, sum of born alive and stillborn piglets, and within-litter birth weight CV (P > 0.05). Tendencies for quadratic effect of feed intake were observed for born alive piglets (P = 0.079), average birth weight of piglets (P = 0.083), and litter weight (P = 0.059). Gilts with lower feed intake during late gestation had reduced percentages of stillborn piglets than gilts with greater feed intakes. The CY decreased linearly (P < 0.05) as the feed intake was increased. No differences among treatments were found at weaning in individual piglet weight and litter weight, as well as in percentage of weaned piglets (P > 0.05). Lactation feed intake decreased as gestation feeding level increased (P < 0.05). No differences in the subsequent cycle were observed among treatments for farrowing rate, retention rate up to the next farrowing, number of total piglets born, born alive, stillborn piglets, and mummified fetuses (P > 0.05). In conclusion, increased feed intake from day 90 of gestation until farrowing resulted in increased maternal BW gain and stillborn rate, but reduced CY and lactation feed intake. A slight increase in birth weight was observed for the 2.3 kg/d treatment. Furthermore, litter growth and subsequent female reproductive performance were not affected by feed intake during late gestation.
