The study aimed to characterise the genetic diversity of Kangayam, Umblachery, Alambadi, Bargur, Pulikulam, Deoni and Ongole cattle breeds present in South India. A total of 96 animals were genotyped for 27 FAO-recommended microsatellite loci. The genotypes were analysed using various bioinformatics tools. A total of 1340 alleles were observed across the 27 microsatellite markers and 7 breeds, with allele count ranging from 6 to 13. The average number of observed alleles obtained in Alambadi, Bargur, Deoni, Kangayam, Ongole, Pulikulam and Umbalacherry cattle were 6.59 ±2.15, 6.96 ± 2.05, 7.52 ±2.42, 6.19 ±2.32, 6.67 ± 2.11, 8.07 ± 2.13 and 7.63 ± 2.34, respectively. The highest number (Na=14) of alleles was observed in Deoni, whereas the lowest number (Na=3) of alleles was noticed in Ongole, Kangayam and Alambadi breeds of cattle. Most of the microsatellite markers were considered informative (PIC > 0.50) and the PIC values showed a significant positive correlation with the number of alleles (r = .517, p = .006), regardless of differences in allele size. The dendrogram among the seven breeds revealed that the Alambadi and Bargur breeds of cattle formed one cluster, while the Kangayam, Umblacherry and Ongole cattle were distinctly different from all other breeds of cattle.

Eight numbers of dung samples were collected from bovine calves aged between 6-9 months in Thalayamangalam village, Orathanadu Taluk, Thanjavur district with the history of chronic watery diarrhoea and jowl oedema. Gross examination of dung samples revealed foul smelling with absence of segments of tapeworms. Dung samples were screened by using sedimentation technique for the presence of parasitic eggs/ova. Microscopical examination revealed the presence of spindle shaped eggs having anterior spine and active miracidium inside the eggs. Based on the morphological features of the parasitic egg, it was diagnosed as Schistosoma spindale infection in calves.

A female Ongole calf aged one year and nine months was found to have nodular development around the left eye and neck region. Clinical examination revealed that the calf had cutaneous papilloma (wart), which was treated with autohemotherapy, ivermectin and levamisole injections along with placement of a ligature around wart's base. On the third day of treatment, a large papilloma on the left lower eyelid dried up and sloughed off. On the tenth day of therapy, the warts on the upper eyelid and neck began to dry and flake off, leaving behind barely visible scars at the original growth sites. The animal underwent an uncomplicated recovery and completely recovered from the ailment.

Fifteen days old Jersey crossbred calf was brought to the hospital with the history of sudden hair fall around the trunk and legs and the other calf was apparently normal in twin birth. Clinical examination revealed severe alopecia in both fore limbs, hind limbs, trunks and easy epilation of hairs, along with erythematous skin and pruritus and mild scaling around its thighs, flanks and trunk. Dermatological analysis of skin scrapings revealed negative for ectoparasites and trichogram showed no hair growth abnormalities. Haemato-biochemical parameters were in normal range except low plasma ascorbic acid (0.16 mg/dL). The case was diagnosed as vitamin C responsive dermatosis and treated with single dose of intravenous injection of 2.5 g of ascorbic acid diluted with normal saline. The owner was advised to follow tab. vitamin C total dose of 2 g/day for 10 days orally. After one week, further hair was loss ceased and complete regrowth of hair noticed after four weeks of treatment. 

A study was conducted  at Institute of Poultry Production and Management (IPPM), Madhavaram Milk colony, Chennai-51.Three hundred and sixty (360) day-old straight run Nandanam broiler - 2 chicks were individually weighed, wing banded and randomly assigned to three different dietary treatments with two replicates  and reared on deep litter system for a period of 8 weeks. The results showed that supplementation of muti-enzyme at the rate of 500g per ton of feed (T2) in Nandanam broiler-2 ration were significantly higher (P<0.01) than control in weight gain of 2nd, 8th  and 0-8 week of age. The feed consumption and feed conversion efficiency was significantly higher (P<0.01) in control compared to treatment. The livability was highly significant (P<0.01) in T3 than control. The carcass characteristics of live weight, heart, eviscerated, giblet and ready-to-cook weight did not show any significant difference in treatment group than control. The cut-up parts of breast yield were highly significant (P<0.01) in T2 than control. The drumstick yield was significantly higher (P<0.01) in control than treatments. The cut-up-parts of back, thigh, neck and wing did not show any significant difference in treatment than the control, but the value was better in enzyme treated group. It was concluded that the production performance was better in supplementation of multi – enzyme at the rate of 500g/ ton of feed and carcass traits was not significantly different between the treatments.

Length-Weight relationship was studied in Oreochromis niloticus niloticus, for a period of nine months from September 2012 to May 2013. The slope value (b) estimated for O. niloticus niloticus of both sexes was found to be 2.3133. The regression equations calculated for female was Log W = -3.4168 + 2.3133 Log L. The correlations coefficient was found to be significant (P<0.01). The significant difference between sexes of the species ‘F’ value was at 1% level. The b value differed from the ideal cube law of ‘3’ as is with the case of length-weight relationship studied in this species else where. The slope value was compared here could be very useful for comparison with the tilapia species in other geographical locations.

The brown paper nautilus, Argonauta hians Lightfoot, 1786 was recorded for the first time from Indian waters while investigating the biodiversity of the molluscs of Gulf of Mannar during June, 2011. One specimen of the said species was collected as an incidental by-catch in the trawl catch off Thoothukudi coast of Gulf of Mannar, from India, between 08º 35’ 22.5" N 78º 27’ 40.9" E and 08º 31’ 91.2"N 78º 25’ 32.7"E at a depth of 305-310 m.  

Abnormalities in size and growth has been observed in the young ones of angel fish (Pterophyllum scalare) of the same brood. Morphological measurements confirm the abnormalities in the affected specimens. As per the reports available, methylene blue treatment during the early life stages may have a teratogenic effect which led to such conditions in angel fish.  

A study was conducted to record the gross thickness of skin in various regions of the body at different age groups on Bakerwali goats. The animals were divided into three age groups viz, neonatal, young and adult. The thickness of skin increased with advancement of age. Neck dorsal showed the maximum thickness and thorax ventral showed the minimum thickness among the different regions in all the groups studied. 

Multicut fodder sorghum Co (FS) 29 was evaluated for its growth and yield performance with the application of different sources of irrigation and nutrients. The experiment was conducted in split plot design with three replications. Main plot consists of treatments with application of irrigation through ground water (I1), domestic sewage water (I2) and ground and domestic sewage water alternatively (I3). The sub plots consist of no fertilisers (control) (N1), application of farm yard manure alone (FYM alone) (N2), farmyard manure + NPK (FYM + NPK) (N3) and NPK alone (N4). The application of domestic sewage water along with FYM + NPK nutrients as per the treatment schedule resulted in higher plant height, leaf length, number of leaves, biomass production, dry matter and biomass yield of multicut fodder sorghum. However, pertaining to nutrient application, nitrogen uptake was higher with application of FYM +NPK but found on par with the application of NPK alone and application of FYM alone.
