IgM was the second most dominant immunoglobulin, which showed a similar decline pattern like IgA. Significant differences were found between the concentrations of IgM in colostrum, transitional and mature milk (Table 2). The mean total IgM values of 0.44 g/L, 0.10 g/L and 0.09 g/L for the three successive stages were somewhat lower than most previously reported means. In a study conducted on Indian mothers, Narula et al.16 reported the IgM concentration in colostrum to be 0.58 g/L, which fell sharply in mature milk (0.24 g/L). In another study conducted in New Zealand, Mickleson and Moriarty15 reported a mean IgM level in colostrum to be 1.13 g/L and in mature milk to be 0.05 g/L (42 days postpartum). On the contrary, there are reports of mean IgM levels, which were much lower than recorded in this study.17, 18 The decline in the IgM level was in agreement with the study conducted by Ogra and Ogra,8 which showed that the highest IgM levels in colostrum were observed in the initial phase of the postpartum period and subsequently, the IgM concentration actively declined in milk during the progression of lactation. Our mean value of IgM is somewhat lower than the Indian value16 but higher than the reported value in New Zealand.15

The study revealed that parity had a significant influence on the immunoglobulin production ability during different stages of lactation. This study showed that the IgA level in the colostrum (P = 0.05) and IgM and IgG levels in transitional milk (P = 0.05 and P = 0.03, respectively) of the multiparous mothers (IgA = 5.58 g/L, IgM = 0.09 g/L, IgG = 0.11 g/L) were lower as compared with primiparous mothers (IgA = 6.58 g/L, IgM = 0.11 g/L, IgG = 0.13 g/L) (Table 3), which was in agreement with the study conducted in the rural Gambia by Prentice et al.27 In our opinion, the difficulty of life in Bangladesh with fluctuations in food availability, disease outbreak together with inadequate access to health services and poor utilisation affect the secretory performance of the mammary alveoli as a woman feeds through many different pregnancies, often starting at a much younger age and usually feeding for longer periods.28 It is reported that 72.8% of women gave first birth at
Spotted white-tailed deer fawns offer one of the most appealing sights in nature. Fawns typically appear walking closely to their protective mother or bounding across a field with seemingly unlimited energy. However, in May and June many fawns are found curled up in the field or forest alone, with no vigilant doe in sight. Is this an orphaned fawn? Almost certainly never!
The doe-fawn bond is very strong. A mother deer will not avoid her fawn if there are human or pet odors on it. Fawns are rarely abandoned, except in extreme cases where the fawn has defects which will prevent its survival. The fawn should be placed in or next to natural vegetation near the location where it was found to provide cover and protection. The doe will avoid the area until the disturbance has passed, after which she will search for the missing fawn. If more than 24 hours have passed, the fawn may need attention from a wildlife rehabilitator.
Premature babies do not receive as many antibodies from their mothers as full-term babies. Their immune systems are not very strong. Premature babies have a greater chance of getting sick from germs like bacteria and viruses.
To study the Chinese human milk N-glycome over lactation, N-glycans were released and separated from serum proteins, purified by solid-phase extraction, and analyzed by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF-MS). In total, 66 different putative N-glycans were found in the colostrum (week 1) and mature milk (week 4) of seven Chinese mothers. A clear difference was observed between milk of five secretor and two nonsecretor mothers, based on the type and relative amounts of the individual N-glycans. The relative levels of the total neutral nonfucosylated and the fucosylated N-glycans in milk of five secretor mothers increased and decreased over lactation, respectively. This pattern could not be observed for the milk from the two nonsecretor mothers. Overall, this was the first study that provided detailed information on individual N-glycans in milk among mothers and over time as well as that fucosylation of N-glycans in milk was associated with the mother's secretor status.
