Two male pigeons that are died due to accidental injury in the college premises after death tissue sample of lung were collected for histoarchitectural observations. The secondary bronchi, parabronchi, atria, infundibula and air capillaries were together with connective tissues constituted lobules of lungs. The epithelium of air capillaries and the endothelium of blood capillaries were separated by basement membrane only. Air and blood capillaries were intermingled with each other to form the blood-gas barrier. Histoarchitectural observations of lungs were made from the section stained with haematoxylin and eosin (H&E). The histological study involves the histological description of external and internal bronchi of the left and right lungs. [ABSTRACT FROM AUTHOR]

Rambouillet sheep (n=15) were subjected to superovulation treatment using FSH (Folltropin-V, Bioniche Animal Health, Canada) during the period between August and November, 2013. The sheep were randomly divided into two groups. Group 1 (n=7) animals were administered 80 mg of NIH-FSH-P1 in six divided doses for 3 days at 12 hour interval in a tapering doses schedule (20 mg, 20 mg, 15 mg, 15 mg, 5 mg and 5 mg) where as ewes of Group 2 (n=8) were given 100 mg NIH-FSH-P1 in the tapering dose schedule (25 mg, 25 mg, 15 mg, 15 mg, 10 mg and 10 mg) as that of group 1. All the ewes received progesterone (P4) impregnated vaginal sponges for 12 days with FSH treatment initiated either on day 9 or 11 and 200 IU eCG along with first/fifth FSH injection. P4 sponges were withdrawn at the time of penultimate FSH injection. Oestrus detection was done using apronized rams from 24-48 hr after sponge withdrawal and those in oestrus were naturally served for 2-3 times at 12 hr interval. Embryos were collected by retrograde surgical technique between day 3 and 5 after oestrus. Animal with two or more corpora lutea (CL) were considered to have responded to superovulation (SOV) treatment. A 57.14 % (4/7) and 75% (6/8) ewes of group 1 and 2, respectively responded to SOV treatment. The ovarian response was highly variable and ranged between two and eight CL irrespective of groups. The mean ovarian response was 2.0±1.06 (14/7) and 2.37 ± 0.8 (19/8) in groups 1 and 2, respectively. The mean number of transferable embryos in groups 1 and 2, respectively was 1.0± 0.57 (4/4) and 1.83 ±0.75 (11/6). The mean ovarian response as well as embryo recovery did not differ significantly (P >0.05) between groups. From the results it may concluded that the reasons for poor ovulation rate (over all 2.2 ± 0.63; 33/15), high anovulation rate (over all 3.4 ± 0.93; 51/15), poor embryo recovery rate (45.45%; 15 embryos/33 CL) as well as less no. embryos recovered per animal (over all 1.50 ± 0.5) need to be investigated and warrant further studies.

The study was carried out on the forearm bones of camel preserved in the department. The distinguished gross anatomical features and various measurements for mean ± S.E. were recorded on different parts of right and left side bones of forearm, but there was no significant difference between these bones of same animal. The radius was more massive than ulna, but the ulna was much longer than radius. Forearm was 58.5±0.91 cm in length, which was constituted by radius (52±0.73 cm) and ulna (58.5±0.91 cm). These two bones were completely fused with each other leaving two interosseous spaces. [ABSTRACT FROM AUTHOR]

The present gross morphometrical studies were recorded on the os-coxae and synsacrum of peacock and peahen. The conjugate and vertical diameter of pelvic girdle in peahen was greater than compare to pelvic girdle of peacock. Pelvic girdle composed of three bones as ileum, ischium and pubis. The biometrical measurement as pre-acetabular and post-acetabular length was recorded in both sexes. The ilio-ischiatic foramen, which were largest foramen in pelvic bones and its maximum length and width were recorded in peacock and peahen. Maximum length of ischium and pubis, obturator foramen were compared in both sexes. The synsacrum was fusion of thoracic, lumbar and sacral bones. The number of vertebrae was recorded on peacock and peahen. These observations are useful in veterolegal cases and further studies. [ABSTRACT FROM AUTHOR]

Present investigation was undertaken on three buffalo bulls (Murrah) to study the leakage of phosphatases during cryopreservation. A total of 18 collections from three bulls (six collections per bull) were utilized for the study. After initial evaluation, each semen sample was diluted in two different extenders viz. Tris egg yolk extender which acted as control and Soya-milk extender as experimental. At the equilibration and post-thaw stages leakage of phosphatases viz. alkaline phosphatase (AKP) and acid phosphatase (ACP) were studied. There was a significant difference in the levels of AKP and ACP at post thaw stages in between the extenders. The leakage of phosphatases was found to increase from pre-freeze to post-freeze stage in both the extenders with better results in Tris egg yolk. [ABSTRACT FROM AUTHOR]

A study was undertaken to assess the efficacy of cysteine hydrochloride concentrations on post-thaw progressive motility, live sperm, acrosome integrity and sperm abnormalities following freezing and thawing in Jersey bulls semen. Semen was collected from 3 purebred Jersey bulls twice a week and 18 collections (6 collections per bull) were utilized in this study. After collection and primary evaluation, samples were divided into four fractions and were diluted in egg yolk tris glycerol extender with addition of cysteine @ 10, 12 or 15 mM (CYS-10, CYS-12 and CYS-15, respectively) and without cysteine (EYTG-C) which acted as control. Filling and sealing of diluted semen samples in PVA straws, equilibration at 4°C for 4 h, freezing in programmable bio-freezer and plunging of straws into liquid nitrogen were followed as per standard procedures. After thawing at 37°C for 30 sec, semen characteristics such as progressive motility, live sperm percentage and acrosome integrity were significantly higher whereas sperm abnormalities were significantly lower in samples containing cysteine @ 10 mM over the control and other dilutors. The results revealed that addition of cysteine @ 10 mM as an additive to semen in tris egg yolk extender, significantly improves the post-thaw semen characteristics, whereas adverse effect of cysteine was evident in its higher concentrations i.e. 12 mM and 15 mM.
