Changes in the blood profile of domestic pigeons (Columba livia) were studied during growth and breeding cycle. Counts of erythrocytes and leucocytes, and values of mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH), blood volume, plasma volume (BV), width of erythrocytes, and length, width and volume of erythrocyte nuclei of squabs almost(More)
Haematocrit measurements and plasma protein electrophoresis were carried out in female pigeons (Columba livia) during the breeding cycle. Non-laying birds showed higher (p < 0.001) haematocrit values than those involved in courtship and mating, nest-building, incubation and feeding and brooding. Significant differences in relative percentage of various(More)
1. Groups of chicks were given a low-residue diet with or without supplements of dietary fibre in the form of wheat bran, wheat straw or bagasse. Growth and food conversion efficiency (g weight gained/g food eaten; FCE) during the first 4 weeks of life were measured. 2. In every one of seven experiments supplementation of the diet with 100 g wheat bran/kg(More)
Several in situ and ex situ conservation strategies have been suggested for the revival of stocks of Tor khudree (Sykes), a threatened species. Cryopreservation of spermatozoa is crucial for the conservation of stocks of endangered species so that sustainable production can be ensured. Among the different extenders, modified fish Ringer (E1) was found to be(More)
Effect of bottleneck sizes, on sexual isolation, mating speed and fertility were studied in D. malerkotliana established from natural population. After 10 generations of laboratory breeding, flies showed incipient sexual isolation between control line and some bottleneck lines and also between bottleneck lines. These findings do not fully agree with the(More)
Intra and interspecific competition experiments involving control and bottleneck lines of monomorphic and polymorphic populations of D.malerkotliana with D.nasuta nasuta have been carried out. Productivity and population size were evaluated in these lines. The results show that control line had higher relative fitness and adaptedness (productivity and(More)
Five cell lines were employed to test the growth-stimulating property of pigeon milk in vitro. All the cell lines except A431 showed good growth response to crude homogenates of pigeon milk. Enhancement of DNA synthesis in quiescent Chinese hamster ovary (CHO) cells by pigeon milk was dose dependent up to a concentration of 1%. In vitro growth stimulation(More)
1. Groups of adult colostimized chickens were given diets with and without dietary fibre in the form of bagasse or wheat straw. The fibrous materials were analysed for their contents of cellulose, hemicellulose and lignin. The digestible energies (DE) and metabolizable energies (ME) of these diets were measured by a balance method. 2. Groups of germ-free(More)
Aqueous extracts of pigeon milk (PM) stimulated the in vitro growth of quiescent CHO cells maintained in culture and caused precocial incisor eruption and eyelid opening in newborn mice. CM-cellulose chromatography of the growth factor of PM enhanced its biologic activity. Rechromatography of CM-active fractions in DEAE-cellulose columns yielded a single(More)
