“…Moreover, as reported elsewhere, the relative amount of K in the neonatal pig was low, increased dramatically during lactation, and then increased with increasing pig weight, resulting in an overall quadratic response (Mahan and Shields, 1998). The findings of the present study are consistent also with previous findings of our research group (Papadopoulos et al, 2008), in which milk production of sows during mid-lactation could be predicted by variations in the urinary levels of K and Ca in sows during mid-lactation. Furthermore the negative correlation between litter size and mineral accretion rate of K and Ca may indicate a dilution of these minerals in the milk of the sow, when litter size is increasing.…”

The present study investigated the effect of a moderate substitution of inorganic mineral sources with chelated mineral sources from four weeks prior to parturition throughout lactation on sow and litter performance. In addition, the aims were to determine whether the mineral source and litter performance affect mineral status and accretion in piglets at birth and at weaning. Forty gestating sows in a commercial pig herd were selected and randomly assigned to two experimental groups, with part of the Cu, Mn, Zn and Fe content of the feed added as either an inorganic mineral source or a chelated mineral source. From each sow, one piglet was randomly selected at birth and at weaning for total body mineral analysis. Neither the performance of the sows and the piglets nor the total body mineral concentrations of the piglets at birth and at weaning were significantly different between the two diet groups (P > 0.05). Fe, Na and P content of piglets at birth were inversely correlated with birth weight (r = -0.447, P = 0.004 for Fe; r = -0.431, P = 0.005 for Na; r = -0.340, P = 0.032 for P). Daily accretion rate of K and Ca of piglets was positively correlated with piglet growth performance during the entire lactation period (r = 0.469, P = 0.008 for K; r = 0.581, P < 0.001 for Ca), and negatively correlated with number of liveborn piglets (r = -0.424, P = 0.014 for K, and r = -0.405, P = 0.027 for Ca). In conclusion, the study documented that partial substitution of inorganic minerals with a chelated mineral source failed to exert significant effects on performance and total body mineral concentrations. The importance of the influence of sow milk production on mineral body stores in piglets warrants further investigation.

“…Currently absence or deficiency of milk yield among mammalian species during the postpartum period is a frequent question (Amir and Cwikel 2005;Papadopoulos et al 2008). Many traditional Chinese herbs have been used to improve lactation potential, with natural raw materials, less side effects and no tolerance and drug-resistance.…”

An experiment was conducted to study the effects of dietary Semen Vaccariae (SV) on mammary development and lactation potential in rats. Forty-eight SpragueÁDawley female rats after parturition were selected and assigned to two groups randomly, with 24 rats each. Control rats were offered basal diets from the beginning to the end of the lactation period. A total of 1% SV was added to the basal diet to form an experimental diet. After parturition, the litter size was culled to eight pups per dam. Estimated milk yield was improved 29.82% (PB0.05) by feeding SV on day 18 of lactation. Serum growth hormone, insulin-like growth factor-1 and prolactin concentrations in dams were significantly higher (PB0.05) in the SV group than in the control group on day 18 of lactation. Dietary SV increased wet weight and DNA contents of dam mammary (PB0.05). The results suggest that dietary SV stimulates mammary development and promotes lactation in rats.
