Data on 566 Tellicherry goats, recorded between 1988 and 2007 were used to study the effect of nongenetic factors on body weight and daily gain from birth to 12 months of age. The least-squares means for body weight at birth and at 12 months of age were 2.17 ± 0.03 and 18.78 ± 0.44 kg, respectively. The preand post-weaning average daily weight gains were 72.41 ± 1.68 and 37.46 ± 1.49 g, respectively, and the associated growth efficiencies were 3.11 ± 0.08 and 1.34 ± 0.05, respectively. Significant differences associated with the year of kidding were observed in body weight, weight gain and efficiency in weight gain at different stages of growth. Growth rate of kids born between December and February was relatively slower than those born in other months and this can result from seasonal changes and suggests that it is necessary to plan the kidding season rationally by controlling the oestrus and mating time. The kids born as twin had lower birth weight and slower early growth rate than those born as single but had a higher postweaning growth rate. The heritabilities of different traits were moderate to high, except for birth weight, which was of low heritability. The phenotypic and genetic correlations among the different body weights were positive and low to high in magnitude._______________________________________________________________________________
Incidence of unusually high numbers of stillbirths was observed at a piggery unit at the Veterinary University research farm in Tamil Nadu State of India. Systematic examination of the tissue from stillborn piglets led to the identification of presence of Porcine circovirus 2 (PCV2). Detailed analysis utilizing electron microscopy, polymerase chain reaction and sequencing confirmed the presence of PCV2 in the tissue of affected piglets. Histopathology analysis of the affected piglet tissue showed lymphoid cell depletion of lymphnodes, spleen and infiltration of liver, kidney, myocardium, etc. Retrospective examination of the morbidity and mortality history in the farm revealed high mortality in young and weanling piglets suggestive of PCV2 infection-induced diseases. This is the first report of emergence of major disease incidence in farmed swine due to PCV2 infection in India.
Abstract:This review summarizesemergingand re-emergingmajor bacterial, fungal, viral and protozoan causes of abortion in cattle. The clinical presentations of disease due to reproductive pathogens are emphasized, with afocus on assisting development of complete lists of major causes that result in abortion in cattle. Clinicians areencouraged to assess clinical presentation, create complete lists of differential diagnoses, obtain appropriate diagnostic samples, maximize diagnostic laboratory support, and avoid zoonotic infections resulting from reproductive pathogens of animals. Thefoundation of an accurate diagnosis of reproductive loss due to infectious pathogens facilitates the prudent use of immunization andbiosecurity to minimize reproductive losses.
SummaryThis study was carried out on 2 309 households in 60 villages with the objective of documenting the performance of Mecheri sheep in their native environment. The study revealed that Mecheri sheep were distributed in Salem, Erode, Karur, Namakkal and parts of Dharmapuri districts of Tamil Nadu. This tract lies in the north-western agro-climatic zone of Tamil Nadu and the climate is generally hot, semi-arid and tropical in nature.The average flock size of Mecheri sheep was 24, of which, there were 1 ram, 17 ewes and 6 lambs. Mecheri sheep of medium size with a compact body and covered with short hairs, which are not shorn. They are light brown in colour. Their profile reveals a slightly Roman nose. Both males and females are polled. The pooled means for height at withers, chest girth and body length at above 24 months of age were 67±0.4, 74±0.4 and 66±0.4 cm, respectively. The body weight of the animals at birth 3, 6, 9 and 12 months of age was 2.82±0.01, 10.9±0.1, 15.6±0.1, 17.6±0.2 and 21.1±0.1, kg respectively. The dressing percentage of males and females was 54.4±0.4 and 51.8±0.5, respectively. Average ages at first oestrus, mating and lambing were 12.1±0.1, 12.4±0.1 and 17.4±0.1 months, respectively. The average lambing interval was 226±0.7 days and the average litter size was one.
Background: Foramen ovalee is an important foramen of the middle cranial fossa. Foramen ovalee is situated in the greater wing of the sphenoid bone, posterior to the foramen rotundum and lateral to the lingula and posterior end of the carotid groove. Through the foramen ovale the mandibular nerve, accessory meningeal artery and lesser petrossal nerve are passing through it. The shape of foramen ovale is ovale in shape as compare to other foramina of the skull, its shape and size is quite variable. Meterials and Methods: A total 250 skulls were used for this study. The skulls were collected with I MBBS student from different medical colleges in south India. Skulls in poor conditions or skulls with partly damaged surroundings of the foramen ovalee were not considered. Maximum length and width of foramen ovalee was measured. Variation in right and left side and sex difference in length and width were calculated, the variations in shape also recorded. Results: The mean value of length of left foramen ovale is 8.5+1.32mm and right was 8.9+1.67mm. In female it was 8.7+1.67mm and male was 8.4+1.71mm. The mean value of width of left foramen ovale is 3.7+1.03mm and right was 3.9+0.98mm. In female it was 3.8+0.92mm and male was 3.7+1.02mm.The shape of foramen ovale was ovale in 69% of skulls, almond in 29% of skulls and round was 2% of skulls. Conclusion: The present study conclude that there is significant difference between sizes of right and left side foramen ovale and found that between male and female foramen ovale sizes also not shown any significance difference. Foramen ovale has practical significance to both neurosurgical and functional cranial neuroanatomy as it provides transcutaneous approaches to the skull base especially in cases of trigeminal neuralgia, as the Gasserion ganglion can be approached through it.
