“…and the second largest at 4 weeks after farrowing (59.0 gin.). This is in agreement with other reports to the effect that the peak of lactation in sows occurs between the third and fifth week (Hughes and Hart, 1935;Smith, 1952Smith, , 1959Lodge 1959a;Allen and Lasley, 1960;Hartman and Pond, 1960). Allen and Lasley (1960) observed breed differences in the time at which the peak was reached.…”

“…Experimental data and literature reviews have been recently presented for yield (Allen and Lasley, 1960) and composition (Neuhaus, 1961;JylUng and Sorensen, 1960) of sow's milk. Most reports have not been concerned directly with variations to be expected in yield and composition among glands within a given sow or among SOWS. The work to be reported was designed to study variation among individual glands and among sows in milk yield and in protein, fat, ash and dry matter content of the milk over a 6-week lactation.…”

“…The results of Pond et al [14], King et al [11 ], Allen and Lasley [ I in Duroc and Landrace x Poland China sows (on the days 21, 17 and 21 of lactation, respectively) and our findings showed that the peak of milk production was reached in the week 3 of the lactation. However, Allen and Lasley [1] ] with Poland China sows, Ferreira et al [6] and GrOn et al [7 with Landrace sows reported that the highest amount of milk production was obtained in the week 4.…”

-Fifty-six lactations, 23 from primiparous Large White x Landrace sows and 33 from I I multiparous sows were controlled. Milk yield was estimated by weighing the piglets before and after sucklings throughout a 12-h period on days 7,14, 21, 28, 35 and 42 of lactation. Total milk yield and milk production per weaned piglet during a 6-week lactation period were 170.0 ± 48.8 kg and 29.4 ± 7.3 kg respectively for primiparous sows and 210.9 ± 33.6 kg and 26.9 ± 5.1 kg respectively for multiparous sows. In both groups, the peak of lactation was reached in the 3rd week and the lowest amount of milk was yielded during the 6th week (33.5 ± 14.3 kg and 23.3 ± 9.9 kg in primiparous sows and 43.3 ± 11.1 kg and 28.0 9.8 kg in multiparous sows). Milk production curve was fitted to a gamma function (R'-= 0.86 in primiparous and R 2 = 0.91 in multiparous sows). The season of farrowing had no significant influence (P > 0.05) on total milk yield and milk production per weaned piglet in primiparous sows. However, total milk yield was increased (P < 0.001) as a result of increased litter size. For each additional weaned piglet, total milk production increased 25 kg, whereas milk production per weaned piglet non-signiticantly decreased by 1.O1 kg (P < 0.2). For multiparous sows, total milk yield and milk production per weaned piglet were significantly affected (P < 0.05) by sow and by parity. In the lactation 4 the milk output was higher than in the lactation 2 and 3. Litter size at weaning did not affect the total milk yield; it affected the milk production per weaned piglet (P <

“…For example, supplementing diets with L-carnitine during lactation sows resulted in higher milk yields than the controls for days 11 and 18 of lactation. Highly significant breed difference was found in the amount of milk produced and in the average size of the litter suckled, whereas a significant difference was found in the average litter weight at the end of the suckling period (Allen and Lasley, 1960;King et al, 1997;Ramanau et al, 2004;Spencer et al, 2003).…”

“…However, if the milk production meets the needs of the litter, it has a positive effect on the piglets' later feed consumption behavior, as well as in their weight gain. 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.…”

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.
