“…On the other hand, we observed that the pig weaning weight tended to be higher sows fed ZnO, as well as ADG during lactation was higher in the piglets from sows fed ZnO. Our results were dissimilar to those observed by other authors [4,[23][24][25] which it no found differences. Also, disagree with Grela., et al [26], once these researchers reported significant differences in the body weight of piglets on days 21, with the addition of microbial phytase in 500 FTU/kg diet of sows.…”

“…In contrast, Grela., et al [26] reported a markedly higher number of liveborn with the addition of microbial phytase in 500 FTU/kg diet of sows, showing that the use of phytase increase the digestibility of some nutrients and can improve the growing pigs. [25], 5 mg/kg [28], however with the supplementation of microbial phytase, this concentration was higher than in the colostrum 27.9 mg/kg Zn [26].…”

“…These our results suggest that sows fed ZnO made more efficient use of nutrient than sows fed the other sources. Zinc concentration in milk is higher than in serum suggesting that the mammary gland provides active transport and regulation mechanisms for some trace elements [25,29].…”

“…Zinc, which is considered to be a cofactor in enzymatic systems, is essential to body growth and the maturation of immune function (Ruel, Rivera, Santizo, Lönnerdal, & Brown, ). Davin, Solà‐Oriol, Manzanilla, Kühn, and Pérez () reported that the concentration of zinc in sow milk was not influenced by the concentration of zinc in sow feed. Therefore, it is difficult to increase the concentration of zinc in the sow milk by feeding sows a high zinc diet.…”

“…Because the requirement of total iron was 10 mg per day for one piglet, it was not adequate for the piglet growth even if all of the iron in the sow milk was completely absorbed (Furugouri & Kawabata, ). Some studies have suggested that iron in milk is not associated with the maternal iron concentration (Davin, et al, ; Domellöf, Lönnerdal, Dewey, Cohen, & Hernell, ). Thus, it was also necessary to supply iron to meet piglets’ need.…”

The objective of the present study was to explore the changes in fatty acids (FAs) and minerals composition in sow milk in order to improve the knowledge about FAs and mineral requirements for piglets. The FAs and minerals composition in the sow milk samples which were collected from ten sows during a period of 16 days of lactation was analysed. The proportion of FAs in sow milk has a significant increase in C8:0, C10:0, C12:0, C14:0, C16:0, C14:1 and C16:1 FAs and the sum of saturated fatty acids (SFAs) according to the lactation period (p < 0.05). The proportion of C18:2 cis‐9,12 FA and the sum of polyunsaturated fatty acids (PUFAs) significantly decreased with the advancing of lactation (p < 0.05). The concentrations of minerals, including potassium, copper, manganese and zinc, were higher on day 1 and day 2 than those on day 13 and day 16 (p < 0.05). On the contrary, the lowest concentrations of calcium, sodium, magnesium and iron and the lowest molar calcium: phosphorus ratio emerged in colostrum (p < 0.05). In summary, our results demonstrated FAs profile and minerals concentrations were changed with lactation period. Better understanding of the changes of FAs and minerals may be valuable to swine nutritionists in the commercial industry. In addition, those results provided some meaningful information for sow's diet formulation during lactation.

Three trials were undertaken to provide an answer to different questions: 1) Are suckling pigs able to maintain physiological serum Zn levels throughout lactation and do these levels vary between high and low BW pigs, 2) Are serum Zn levels in pigs soon after weaning a predisposing factor for diarrhea? and 3) Is it possible to increase serum Zn levels at weaning by supplementing Zn during lactation. In Trial 1, blood samples were taken from pigs during lactation. Eight pigs (one piglet per litter) had blood drawn at d 0 (farrowing), 7, 14, 21, and 28 (weaning), and 60 pigs (selected from the whole farrowing batch with 35 sows), categorized as either heavy (8.63 kg) or light (5.50 kg) had blood drawn at d 28. Serum Zn levels at birth were 1.2 mg/L and decreased (P < 0.01) to 0.67 mg/L at d 28. Heavier pigs showed greater (P < 0.01) serum Zn levels (0.98 mg/L) than light body weight (BW) pigs (0.79 mg/L). In Trial 2 blood samples were obtained from 240 pigs at weaning (26,2 ± 2,5 days) with an average initial BW of 6.94 ± 1.87 kg and were distributed into 24 pens (10 pigs/pen) by body weight. Diarrhea incidence was recorded daily from d 0 to d 35 post-weaning. From the 240 pigs, a group of 110 pigs with uniform BW (6.5 ± 1.9 kg) was selected and separated into two groups based on serum Zn levels at weaning with 55 pigs with low serum Zn (LZn; < 0.71 mg/L) and 55 pigs with high serum Zn (HZn; > 0.9 mg/L). Pigs with LZn were 2.49 times as likely to have diarrhea as pigs with HZn (P < 0.02). In Trial 3, a total of 96 suckling pigs were allotted 4 treatments that consisted of the daily administration of 0, 6, 18 or 30 mg of Zn as Zn Citrate in capsule-form during the last 7 d of lactation. Pigs were individually weighed, and blood samples were obtained on d 14, d 21 (weaning), and d 7 after weaning. Serum Zn levels linearly increased by day as Zn citrate supplementation increased (interaction, P < 0.001). However, only light pigs supplemented with 18 and 30 mg/L of Zn experienced an increase in serum Zn levels during lactation. In conclusion, a decrease in serum Zn levels occurs during lactation, and is more severe in low BW pigs. Low Zn status (< 0.7 mg/L) at weaning may be a predisposing factor for diarrhea. However, Zn supplementation during lactation can mitigate this decrease in light pigs.
