“…Birth weight in pigs has been linked to differences in both growth rate and body composition. Low birth weight pigs exhibit a 15 % to 30 % lower growth rate (compared to medium and high birth weight pigs) in the 1st month of postnatal life (Campbell & Dunkin 1982, Wolter et al 2002, Poore & Fowden 2004, Gondret et al 2005, Škorjanc et al 2007. Based on chemical analysis of the whole body at birth, Rehfeldt & Kuhn (2006) reported that low birth weight pigs have less fat and protein and more water than their littermates.…”

The purpose of this study was to use quantitative magnetic resonance (QMR) to measure changes in the body composition of piglets during growth from birth to 4 kg body weight. Using QMR, 60 pigs were scanned an average of 5 times starting at 2.7±1.3 days of age (1.95 kg) and finally at 13.1±4.3 days (4.14 kg). Regression analysis revealed that the rates of total body growth and fat and lean deposition were linear throughout this period. Subsequently, a second group of 235 pigs (109 males and 126 females) were scanned twice, first at 2.7±1.2 days of age and then at 13.4±3.1 days of age. The mean (±SD) rate of total body growth was 230±57 g/day. The rates of fat and lean deposition were 40±13 g/day and 191±52 g/day, respectively. The rates of both fat and lean deposition were highly correlated (P<0.001) with total body growth rate (R 2 =0.81 and 0.93, respectively) and the coefficient of determination between the rates of fat and lean deposition was 0.71 (P<0.001). The results of this study demonstrate that QMR is a useful method for measuring changes in body composition in neonatal pigs. Furthermore, the results indicate that during the period of growth from birth to 4 kg, the rates of both fat and lean deposition are linear and highly correlated with total body growth.

“…In the present study, the BW of piglets was 1.52±0.11 kg, which is higher than the 1.18±0.12 kg of the previous study. It has been reported that birth weight affects weight, growth performance, backfat, and longissimus muscle area from pre-weaning to slaughter (Skorjanc et al, 2007;Fix et al, 2010). Skorjanc et al (2007) reported that high-birth-weight piglets had higher BW at weaning and low-birth-weight piglets had 17 to 22% lower ADG when compared with heavy and intermediatebirth-weight piglets.…”

The present study evaluated the optimal duration of creep feeding that improves the growth performance and fecal score of piglets and the performance and estrus interval of sows. Sixteen sows (Yorkshire × Landrace) and their litters were used in this 24-day trial. Dietary treatments were: Treatment 1, in which creep feed was not provided; treatment 2, in which creep feed was provided at the 7th day of life (day 7 to weaning); treatment 3, in which creep feed was provided at the 14th day of life (day 14 to weaning); and treatment 4, in which creep feed was provided at the 21st day of life (day 21 to weaning). There was no difference in body weight or loss, backfat thickness or loss, or estrus interval among treatments in the sows. Piglets in treatment 2 had higher body weight (BW) than pigs of treatments 1, 3, and 4. In addition, piglets in treatment 3 had higher BW than those of treatments 1 and 4. From birth to weaning, piglets of treatments 2 and 3 had higher average daily gain than those of treatments 1 and 4. There was no difference in fecal score of piglets among treatments. Piglets fed creep feed initiated from the first week have higher BW and average daily gain at weaning compared with those initiated from the second and third weeks, indicating that a longer duration of creep feeding improves the growth performance of piglets.

“…A positive correlation was found between the amount of milk produced by a sow and the amount of creep feed consumed by her litter, with the piglets of those sows producing the most milk consuming the most creep feed (Allen and Lasley, 1960;Renaudeau and Noblet, 2001). Skorjanc et al (2007) indicated that neither milk production after the second week of lactation nor consumption of creep feed is sufficient enough to cover the nutrition needs of fast-growing piglets. There is still a lack of optimization of nutrient in the pre-weaning period, especially for heavier piglets with their higher growth potential.…”

Abstract. The aim of the present study was to investigate the effect of liquid milk supplement on litter performance (weight development of the piglets, weaning weight and mortality) and on sow back-fat thickness change during the suckling period.Data were collected from 150 litters, with the weight of a total of 1709 piglets measured at birth, at 14 days of age and at weaning (28 days), respectively. Sow (n = 150) back-fat depth was measured the day before farrowing, 14 days after farrowing and at weaning. In the control group (n = 363), the piglets were suckled and got pre-starter feed from day 10. In the four experimental groups (MS1; MS2; MS2 and MS4; n = 1346), the piglets received additional milk replacer in various concentrations from the 10th day of life. While there were no significant differences in birth weight between the control and experimental groups, we did find significant differences between the 14-day weights and weaning weights. The milk supplement significantly reduced mortality compared to the control (11.6 vs. 4.9; 5.9, 8.9; 8.3 %). However, there were no statistically significant differences between litter homogeneity data, based on the CV% of piglet weight. Three experimental groups (MS1, MS2 and MS4) were more homogenous compared to the control group at weaning (25.3 vs. 20.9; 20.3; 20.3 CV%). Based on the examination of sow back-fat thickness reduction, there were significant differences between the control (C) and MS3 groups (7.61 vs. 5.57 mm reduction, P < 0.05) during the suckling period. These results demonstrate the advantage of milk replacer on weaning weight. Litter homogeneity, piglet mortality and back-fat thickness of the sows were affected by providing milk replacer to the piglets during the suckling period.
