Title: Studies on Certain Serum Metabolites in non Pregnant and Pregnant Bannur Ewes
Abstract :
A study was undertaken with the objective of making an insight in to the changes with respect to the level of certain metabolites in non pregnant and pregnant Bannur ewes which are indicative of their nutritional status and physiological well being. Eighteen Bannur ewes maintained under identical managemental conditions in a semi-intensive rearing farm which were of two to four years of age are categorized in to three groups, comprising of six animals in each group, such as non pregnant (Group I), early pregnant (Group II, at 20 to 35 days of pregnancy) and late pregnant (Group III, at 105 to 120 days of pregnancy) ewes based upon ultrasound imaging technique. The metabolites such as serum levels of β-hydroxybutyrate, glucose, total protein, blood urea nitrogen and lipid
profile components were determined at 0, 7 and 15th day of sample collection.
Title: Domestication of Anemone Fishes with High Fecundity and Spawning Efficiency under Captive Condition for Indian Scenario
Abstract :
This present study is developed to understand the fecundity rate of seven different anemone fishes cultured in captivity.The efficiency of
quality eggs of anemone fishand their developments aremuch important in marine ornamental aquaculture to enhance the production value.Hence, the experiment states that good feeding habitsof the brooders with mixed diets would increases thequantity and quality of eggs.In addition, the ideal water quality parameters like temperature-27±20C, salinity-28±1ppt, NH-4-0.001ppm, dissolved oxygen 4.0±1 ppm, pH-7.7±0.2, light intensity 2500 to 3000 lux, with photoperiod (12L:12D). The feeding time was maintained thrice a day (07:00, 11:00 and 16:00 hrs)and organic wasteswere removed daily whilewater exchanged 30-40% per week.The sufficient quantity of oyster, musselsand shrimp consumed by the brooders(A.  percula, A. clarkii,  A.  sebae,  A.  sandaracinos,  A. melanopus, A. frenatus, and A. ocellaris) were
0.470g, 1.390g, 1.650g, 0.300g, 0.380g.
Title: Ovulatory Failure in Dairy Cows: A Review
Abstract :
A syndrome associated with conditions leading to anovular follicles or to cystic ovaries is that of ovulation failure. Condition is obviously
multicausal, with some findings supporting the theory that is hereditary, and affected by the season of the year. However, most evidence is consistent with the lack of an LH surge being the critical underlying physiological change that leads to anovulatory condition. Diagnosis of anovulation can only be made retrospectively, by noting that a follicle persists longer than expected. It was reported that cows can spontaneously recover from ovulatory failure by mechanisms that still remain unclear. Improvement in energy status can reduce the period of anovulation. In the various hormonal treatments responses are not uniform, since they appear to be dependent on factors influencing the prevalence of ovulation failure.
Title: New Emerging Androgenic Actions in the Regulation of Sperm Production and Function
Abstract :
Androgenic actions are determinant for sperm production and function and, thus, for male fertility. Androgens exert their effects by
interaction with the androgen receptor (AR), a transcription factor that modulates gene expression in target-cells and tissues. Variants of AR protein have been identified in the testis, revealing a new complexity in androgen signaling pathways. In addition, androgens may evoke responses by controlling intracellular calcium (Ca2+) levels and/or activating Ca2+-dependent pathways. However, until recently the knowledge about the role of androgens controlling testicular expression and activity of membrane and intracellular Ca2+ regulatory proteins was very limited or inexistent. Also the function of Ca2+ in sperm maturation in the epididymis only recently started to be known. This review describes recent advances identifying new AR isoforms in the testis, as well as the novel actions of androgens as modulators of Ca2+ homeostasis
in reproductive tract discussing the consequent impact for male fertility.
