“…Moreover, fostering strategies could lead not only to lower pre-weaning mortality, but also to higher daily gain in litters with similar BW (Deen and Bilkei, 2004). As reported in previous studies (Coffey et al, 1994;Yang et al, 2009), greater litter weight at weaning and higher ADG were observed in litters nursed by multiparous sows as compared with those nursed by primiparous ones.…”

Farrowing is an intrinsically risky process for both the sow and the piglets that can cause welfare and economic problems. The effects of the non-steroidal anti-inflammatory drug meloxicam on post-farrowing behaviour of sows, and the performance of piglets were investigated. A total of 48 sows were randomly allocated at the day of farrowing (day 0) into two homogeneous groups regarding parity, and treated with either meloxicam or saline solution as placebo. For each sow, number of position changes, total time lying and standing or sitting, feed intake and rectal temperature (RT) were recorded during 3 days after farrowing. Piglets were individually weighed at farrowing and at weaning. The number of position changes did not show significant differences between treatments (P 5 0.79). Sows spent significantly less time lying during day 13 after farrowing in the meloxicam group than in the placebo group (P 5 0.04). Feed intake and RT showed a parity effect (P , 0.001 in both cases); however, no treatment effect was observed (P 5 0.67 and P 5 0.47, respectively). Pre-weaning mortality rate in piglets was not affected by treatment. In litters from multiparous sows, piglets of low birth weight (defined as percentile 15: BW ,1180 g) had an average daily gain significantly higher in the meloxicam group than in the placebo group (196.6 6 7.2 v. 166.6 6 9.1 g/day; P 5 0.03). Although the administration of meloxicam 90 min after farrowing showed a positive effect on the total time lying of the sows, additional investigations are required to better qualify relevant indicators of pain following farrowing in sows and to specify the analgesic effects of meloxicam on piglet performance.

“…Instead, new born piglets from sows on the MLys gestation diet were lighter than those from the other experimental treatments. Our findings are in agreement with the results found by Mahan (1998), comparing two levels of Lys in the gestation diet (5.5 and 7.5 g kg -1 ) and Yang et al (2009). Second-parity IB sows would have increased lysine requirements in comparison with multiparous sows, following the pattern described by Pettigrew & Yang (1997) for young and older gestating sows of conventional or lean genotypes.…”

“…Additional dietary Lys reduced urea in plasma in parallel with increased BW gain. On the other hand, the observed levels of urea in plasma are much lower than those reported for gestating sows of conventional breeds, usually fed diets containing higher concentrations of protein (Clowes et al, 2003;Yang et al, 2009). In the present study, lower levels of plasma creatinine have been observed in comparison with those found in leaner gestating sows by Clowes et al (2003), who noticed that plasma creatinine concentrations were linearly related to total N retained.…”

“…Kusina et al (1999) found in primiparous sows, given approximately 27 MJ ME d -1 , increased weight gain with increasing lysine intake from 4 to 16 g d -1 and no influence of lysine intake in gestation on total BW loss during lactation. Yang et al (2009) reported that increasing dietary lysine during gestation (8.2 vs. 5.9 g kg -1 diet) augmented sow BW and backfat thickness, the effect being greater in multiparous than in primiparous sows.…”

Ninety purebred Iberian (IB) sows in second or third parity were used to determine the effects of dietary lysine (Lys) concentration during last third of pregnancy on sow and litter performance. The sows were randomly assigned to one of three dietary treatments: 5.5 (LLys, Control), 7.4 (MLys) and 8.7 (HLys) g Lys kg -1 diet. Feed allowance was 2.30-2.33 kg d -1 . Close to farrowing a conventional lactation diet was used. Dietary Lys did not affect body-weight (BW) gain in late gestation of second-parity sows. However, in third-parity sows, a strong tendency was observed for BW gain to increase during late pregnancy with dietary Lys levels higher than 5.5 g kg -1 (p = 0.061). Body-weight losses during lactation were never influenced by Lys supply. A strong tendency (p = 0.064) for a lower ratio between piglets born alive and total piglets born was observed in second-parity sows fed the Control gestation diet. Litters and piglets from sows on this diet had the lowest weight at birth (p < 0.05). In contrast, third-parity sows on the MLys diet gave birth to piglets with the lowest BW (p < 0.05). Differences in piglets´ BW or litter weight at weaning were never significant (p > 0.05). In conclusion, under moderate energy supply, adequate reserves for subsequent lactation can be achieved in second-and third-parity IB sows with a daily provision of at least 17.2 g lysine over the last third of pregnancy, what implies a substantial increase in protein supply respect to traditional practices.Additional key words: dietary lysine; dietary protein; Iberian pigs; lactation; late pregnancy.* Corresponding author: jose.aguilera@eez.csic.es Received: 18-03-13.

“…Yet given that increased AA have not been reported to increase milk fat (Dourmad et al, 1998;Kusina et al, 1999), it remains unclear how dietary AA influence preweaning mortality. Sows fed higher AA had marginally higher milk protein content (Yang et al, 2009), which potentially could be related to the changes in survivability. Certainly, as litter sizes increase and preweaning mortality becomes more challenging on many farms, the enhancement of piglet survival based on late gestation feeding is an area that needs further exploration.…”
