An experiment was conducted to study the effect of dietary supplementation of calcium, carnitine, zinc and their combinations for 5 weeks in eighty adult crossbred cocks which were divided into eight treatment groups each consisting of ten cocks. Cocks were fed with treatment diets. The treatment groups consisted of control (T1), control + calcium 2 per cent (T2), control + carnitine 250 mg/kg (T3), control + zinc 100 mg/kg (T4), control + calcium 2 per cent + carnitine 250 mg/kg (T5), control + calcium 2 per cent + zinc 100 mg/kg (T6), control + carnitine 250 mg/kg + zinc 100 mg/kg (T7) and control + calcium 2 per cent + carnitine 250 mg/kg + zinc 100 mg/kg (T8). Semen volume revealed no significant difference between treatment groups during five weeks period. Overall sperm motility was significant (P<0.01) between treatment groups except between T4 and T5 groups. Overall sperm concentration was significantly (P<0.01) higher in all treatment groups compared to control. Inclusion of calcium, carnitine, zinc and their combinations had significantly (P<0.01) reduced the overall dead and abnormal of sperms when compared to the control group. The results revealed that inclusion of 2 per cent calcium, 250 mg/kg of carnitine, 100 mg/ kg of zinc and their combinations in feed improved the sperm motility and concentration in cross-bred cocks. 

Ten cattle with severe generalised skin lesions due to dermatophilosis were taken up for the study. Typical exudative dermatitis lesions with matting of hairs, thick scab formation and fissures on the skin were noticed in lower limbs, udder, perineum, inguinal region, axilla, neck and ears. Haematological analysis revealed anaemia and an increase in the absolute eosinophil count in affected animals. Serum biochemical estimations revealed hypoalbuminaemia, hyperglobulinaemia, a decrease in A/G ratio, increase in the blood urea nitrogen value and decrease in the zinc level in affected animals

Di butyl phthalate (DBP) is a most important plasticizer which is suspected as reproductive toxicant and exposure to it has the  potential effect on the human as well as animal reproductive system. The research work was conducted to evaluate the repeated dose toxicity of di butyl phthalate in male wistar rats. The animals were divided in four different groups with 12 male rats in each group.  Group I served as control and was administered corn oil (2 ml/kg body wt.) while groups II, III, and IV were administered DBP orally at  the dose rate of 500, 1000 and 2000 mg/kg respectively for consecutive seven days. Three rats from each group were sacrificed at 24 hrs, 7th day, 14th day and 21st day after initial dosing. There was gradual decrease in WBC count, RBC count, Hb, HCT, MCV, MCH, MCHC, gradual increase in albumin, gradual decrease in total protein, glucose values, gradual decrease in relative weights of the  testes, epididymis, prostate and seminal vesicles as well as increase in liver weight with increase in dose of DBP in group II, III and IV as compared to control group at different intervals of sacrifice. Grossly reductions in the size of testes were observed only in rats that belonged to high dose group IV on 21st day. The plasticizer DBP was found to produce histopathological lesions in male reproductive organs as well as in liver in dose dependent manner after oral administration. The finding suggested that DBP can cause toxicity  lesions in male reproductive organs especially in testes and epididymis at the dose rate of 500 to 2000 mg/kg body weight in wistar rats.

An investigation among fifty each tribal and non-tribal dairy farmers in four dairy dominated development blocks of Cachar district of Assam revealed that, among tribal and non-tribal farmers attitude towards dairy farming, economic motivation and source of motivation for dairy communication were found to have favourable scores with positive and significant correlation with communication behaviour. Regression analysis revealed that source of motivation for dairy communication crucially influenced communication behaviour of dairy farmers. Further, there louid significant difference between the tribal and non-tribal dairy farmers indicating sensitive strategies for dairy development in the area involving the veterinarians. 

Diet of mud crab S.tranquebarica consists of crustaceans, mollusks, fish remains, detritus, debris and undigested flesh. Quantitative analysis of the gut contents contributed 53.18% crustaceans, 24.69% molluscan remains, 16.91% fish remains and 3.02% & 1.23% of detritus and debris respectively. The study indicated that this species is primarily predators of sessile and slow moving benthic macro invertebrates. The presence of detritus, debris and undigested flesh items in the stomachs suggested that the crabs are detritivorous consuming fresh and decaying flesh of all kinds. The sex wise and size wise of diet in these crabs may be largely due to relative abundance of prey species in the habitat or related to change in cheliped strength and foraging behaviour.

Swiss cheese samples collected aseptically from private dairies were analysed for the presence of Penicillium citrinum and for the efficacy of antimycotic agents against P.enicillium citrinum. The spore suspension of Penicillium citrinumand antimycotic agents like pimaricin and potassium sorbate at specified concentrations were added to cheese and stored at 250 C for 21 days. The keeping quality of cheese was assessed at 0, 7, 14 and 21 days. On statistical analysis, pimaricin at 10 ppm concentration was found to be highly significant (P <0.01) over 5 ppm of pimaricin, 500 and 1000 ppm of potassium sorbate with regard to anti-mycotic effect.

The study of the influence of aqueous and hydro alcoholic extracts of Tinospora cordifolia on human mammary tumor cell line MCF-7 is a common way of discovering potential therapeutics for treating people suffering from hormone-dependent problems and diseases. In the present study, the cells were treated with the extracts at three different doses viz., 200 μg/ml, 400 μg/ ml and 600 μg/ml. Both the extracts produced degenerative changes in the cell in dose-dependent manner with maximum effect being noticed at the dose level of 600 μg/ml. Thus, these findings suggest that the extracts from Tinospora cordifolia have potential for acting as an antiproliferative agent in mammary tumour.

The present study was carried out to evaluate the effect of curcumin on lipid peroxidation and antioxidant levels in DMBA (7, 12 Diemthyl Benanthracene) induced mammary carcinogenesis in rats. Twenty four Sprague-Dawley rats were equally distributed to control, DMBA, Tamoxifen (Standard drug) and curcumin groups. DMBA group showed significant (P<0.05) increase in lipid peroxidation and antioxidants superoxide dismutase (SOD) and catalase (CAT) levels besides reduced glutathione (GSH). Whereas, curcumin and Tamoxifen treated groups did not show any significant difference in lipid peroxidation and antioxidant status when compared to the control. Selective growth advantage of tumour cells was evident in the DMBA group and curcumin was able to prevent lipid peroxidation.

A study was conducted in buffaloes suffering with horn affections .The physiological and haematological parameters were within the normal limits in all the horn affections, but the plasma cortisol and C-reactive protein were more than the normal levels in all the horn affections for initial periods. A radiological sign like increased radio-opacity was noticed in the septic horn cases. Microscopic examination of biopsy samples of horn and skin following amputation revealed normal histology except in horn cancer where squamous cell nests and mitotic figures in the squamous cells were observed.

Campylobacter is the commonest reported bacterial cause of infectious intestinal disease. To study the epidemiology of Campylobacter infection among children, 100 stool samples along with patients anamnesis were collected from the clinical diarrheic reported to Enterology unit of Institute for child Health and centre for Children, Egmore, Chennai, Tamil Nadu between May 2013 to June 2013. Samples were subjected to traditional culture and modern PCR techniques, both of which revealed same results of 13% prevalence of Campylobacter sps (8% C.jejuni & 5% C.coli). Analyzing the patients anamnesis to study the epidemiological determinants, sex has a significance (P<0.05). Age and residential area have no significance and summer season and cross contamination could be probable determinants for the infection.
