“…In addition to being a high energy source, it also possesses growth-promoting factor(s) capable of stimulating the growth of mammalian cells (Shetty et al 1992b). Recent work from our laboratory has also revealed that the mitogenic activity of PM homogenates remains unaltered even on exposure to harsh denaturing conditions such as treatment with urea, dithiothreitol guanidine hydrochloride and trypsin, and that its specific activity of growth stimulation (aHthymidine incorporation-mg protein-1) is greater than that of cow, goat, buffalo and human milks (L. Bharathi and S.N.…”

“…It should be mentioned that the parent pigeons do not store PM at any time in their crop cavity and hence the samples had to be obtained (once a day) from freshly fed squabs. The time elapsed from parental feeding (by regurgitation) to surgical collection of PM was about 1-2 h. The collection was restricted to the first 5 days because beyond day 5 of secretion the PM is normally mixed with increasing proportion of grain (parent food) with the result that it is difficult to get it in pure form (Shetty et al 1992b). The samples collected on different days of secretion (contamination with grain, if any, was sorted by hand) were separately pooled and stored at -20 ~ until used.…”

It contains (in percentage) 75-77 water, 9-13 protein, 9-11 fat, 0.9-1.4 carbohydrates, 0.8-1.1 ash, 0.10-0.12 nonprotein nitrogen, and has an energy content of 5.6-6.8 kcal-g-1 (Shetty et al 1992b). Squabs fed with PM exhibit a 22-fold increase in body weight in the first 3 weeks of life (Shetty et al 1992b).…”

Pigeon milk, a nutritive secretion from the crop of breeding pigeons, was tested (on v/v basis) for growth factor activity either separately or in combination with other growth supplements. Synthesis of DNA in confluent monolayers of quiescent Chinese hamster ovary cells was enhanced by the homogenates of pigeon milk in the presence of both fetal bovine serum and bovine serum albumin, although the response with fetal bovine serum was greater than that with bovine serum albumin. The in vitro growth stimulation by pigeon milk was also reflected in the increase in cell number. Specific activity of pigeon milk growth factor, measured against both Chinese hamster ovary cells and mouse embryo fibroblasts, was found to be higher than that of fetal calf serum, fetal bovine serum, and goat, horse, pig and human serum. The growth-stimulatory property of pigeon milk did not change in the first 5 days of its secretion.

“…Other important things to consider are that replacement clutches are common and also the time needed for completing a single clutch is relatively short. Both parents share incubation and chick development is quite fast, given the use of the energyrich cropmilk (Shetty et al, 1992). Moreover, pigeons can overlap clutches (Hetmanski & Wolk, 2005;Johnston & Janiga, 1995), which enables the clutch interval to be shortened, thereby increasing the number of clutches within a season.…”

Abstract.A study on a population of speckled Columba guinea and feral Columba livia pigeons on the University of South Africa's (UNISA) Muckleneuk campus was conducted from March 2013 to February 2014. Morning and evening counts, once a week, were conducted by an observer who also noted the presence of breeding activity and the use of ledges in relation to aspect and levels of buildings. The pigeon population index fluctuated seasonally. Breeding occurred throughout the year, with notable peaks and declines relating to physiological and population dynamics. Opportunistic use of the crop availability was made during optimal production periods, while conserving energy when not favourable. Site selection in relation to building aspect indicated significant differences in all the seasons except for winter, while a positive significant relationship between level height and pigeon numbers was recorded. Knowledge of pigeon ecology and their use of urban landscapes contribute to further understanding wildlife management.
