“…Similar results have been reported by Reese, Moser, Peo, Lewis, Zimmerman, Kinder and Stroup (1982) and King and Williams (1984a) who found that farrowing rate, ovulation rate and litter size were unaffected by food intake of the sow during its first lactation. Food intake during lactation failed to affect either subsequent conception rate or ovulation rate.…”

Seventy-two animals were used in an experiment to study the response of first-litter sows to graded increases in daily food intake during a 28-day lactation. Six food intakes, ranging from 1-5 to 4-8 kg/day were compared. The results showed that both live-weight loss and backfat loss during lactation increased linearly as food intake decreased (P < 0-01).Subsequent ovulation rate was unaffected by food intake but both weaning to mating interval (Y,, days) and the proportion of sows exhibiting oestrus within 8 days of weaning (Y 2 ) improved linearly with increase in daily food intake during lactation (X, kg) (P < 0-01); the respective linear regressions being Y, = 39-0 -6-26^ and Y 2 = 0-198A" -0-15. A sub-group of 24 gilts which were older at first conception (340-5 v. 213-5 days; P < 0-01) exhibited oestrus sooner after their first litters were weaned (12-8 v. 22-1 days; P < 0-05) than the remaining 48 younger animals.Nitrogen balance increased linearly with food intake (P < 0-01) but even at the highest food intake, nitrogen balance remained negative (-15-5 g N per day). Food intake had no effect on the growth rate of piglets to 3 weeks of age but in the 4th week of lactation there was a quadratic increase in piglet growth rate as sow food intake increased (P < 0-01). c '3 £ 10 •s.

Reproductive performance, body weight and body condition of breeding sows with differing body fatness at parturition, differing nutrition during lactation, and differing litter size

One hundred and two Large White × Landrace Fl hybrid sows were allocated over four parities in a factorial design to two levels of target P2 backfat thickness at parturition (20 mm, F v. 12 mm, T), two levels of lactation feeding {ad libitum, H v. 3 kg/day, L), and two sizes of sucking litter (six v. 10). Sows attained 13 mm P2 when first mated at 126 kg live weight. Fatness (P2, mm) at weaning was significantly influenced by target fatness at parturition (14·2 v. 9·3), lactation feeding level (13·7 v. 10·0), and litter size (12·7 v. 11·0). Changes in backfat (P2, mm) during 28-day lactation were significantly influenced by target fatness at parturition (—5·0 v. —2·5), lactation feeding (-2 0 v. —5·4), and litter size (—2·9 v. -4·6). Sow live weight (kg) at weaning was significantly influenced by target fatness at parturition (211 v. 192), lactation feeding (218 v. 186), and litter size (208 v. 196). Changes in live weight (kg) during 28-day lactation were significantly influenced by target fatness at parturition (—26 v. — 12), lactation feeding (—5 v. —31), and litter size (—12 v. —25). With multiparous sows only, total food intake during 28-day lactation was negatively related to total food intake in pregnancy. Change in backfat (P2, mm) during 28-day lactation = -0·28 - 0·27 P2 at parturition + 0·04 lactation food intake — 0·50 litter size. Change in live weight (kg) during 28-day lactation = -3·8 — 0·15 live weight post partum + 0·36 lactation food intake — 3·3 litter size. Sows with target fat levels of 20 mm P2 at parturition had better food conversion efficiencies than sows with target fat levels of 12 mm. Target fatness at parturition, and especially lactation food intake, but not litter size, significantly influenced the interval (days) from weaning to oestrus in parity 1 (9·1 v. 14·2 and 7·8 v. 15·3, but 11·6 v. 11·5), while n i subsequent parities only litter size influenced the interval (days) from weaning to oestrus (6·0 v. 8·0). Birth weight (kg) of piglets was influenced only marginally by target fatness at parturition (1·4 v. 1·2) in parity 1, and not by the other factors, or in subsequent parities. Piglet growth rate was affected by both target fatness at parturition and litter size, but by lactation feeding level only in the last week of lactation. The relationship between fatness at weaning (mm) and the weaning to oestrus interval (days) for primiparous sows can be expressed as 26·6 — 1·28 P2. High level feeding in lactation imparted production and efficiency benefit in both primiparous and multiparous sows, while pregnancy feeding to a target of 20 mm rather than 12 mm at parturition was of benefit for primiparous sows.

“…The influence of low levels of feed intake during lactation on embryo survival is less clear with reports of no effect (King and Williams 1984a,b) or decreased embryo survival (Hughes et al 1984; Kirkwood et al 1987a,b There are many reports in the literature concerning the influence of feeding fatsupplemented diets to sows on sow and piglet performance within the treatment lactation (e.g. Reese et al 1982;Cox et al 1983). …”

“…A major criticism of the few reports available is that experiments have been limited to only one (e.g. King and Dunkin 1986) or two lactations (Reese et al 1982;Johnston et al 1986 Fenton and Fenton (19'79 No consistent treatment effect on preweaning piglet mortality was evident (Table 3). …”
