Research

The following university sub projects are in operation from 1.4.03 for a period of one year

Antibiogram for mastitis causing organism - This project is being implemented to identify the region specific antibiotic to successfully control mastitis in this region.
Evaluation of Performance of Mini broilers in Pennagarm block with reference to Economics - This project is implemented to estimate the cost of production, marketing and returns from mini broilers, which will suggest ways to reduce the cost of production and to explore new avenues for the small and marginal farmers.

Disease diagnosis/ Investigation

Collection and examination of biological materials on autopsy and investigation for disease diagnosis in livestock and poultry.

Extension

Advisory services on housing, feeding, watering, health coverage and marketing for profitable livestock and poultry farming
Preparation of economically feasible livestock/ poultry project proposals to enable the farmers to avail bank finance.
Participation in mass contact programmes.

Salient Findings

Panacur was found to be an effective antihelmintic against Strongyles, Amphistomes, Fasciola and tape worms
Liv-52 syrup when added in drinking water @ 30ml/333 chicks from day old to one week of age, broiler chicks gained 211.50 g at the end of 7th week
Bonnisan included at the rate of 60ml/333 chicks in drinking water from day old to one week resulted in an increased weight gain of 134 grams /broiler chick at the end of 7th week.
The average livability of Keystone White Leghorn commercial strain hybrid chicks up to 20th week of age was recorded as 88.33%.
The per cent incidence of Lymphoid Leucosis in commercial hybrid layer poultry strains of KEYSTONE GOLDEN, DEKALB and BABCOCK breeds was 6%, 4.27% and 3.98% respectively.
Brooding in layer birds were found to reduce with supplementation of Vitamin B1 and Lucerne meal.
During outbreaks of Coccidiosis, addition of B-Complex vitamins aggravated the pathogenecity of the Oocysts of Coccidia.
Abortions were more frequent when pregnant animals were fed with cholam stalks, which contained fungal spores that released toxins. Removal of cholam stalks feeding prevented recurrence of the conditions.
Usage of red coloured lights in broilers resulted in increased weight gains by 110 grams at 8th week when compared to the control groups reared in candescent light.
Codrinal was effective in controlling intestinal form of Coccidiosis in poultry.
Detailed investigation revealed that during an acute outbreak of Ranikhet disease in layer farms, the usage of RDVK vaccine to the affected flocks controlled the course of the disease and minimized mortality.
In Palacode area, out of 193 white cattle males, 13 were found positive for Nasal Schistasomiasis, while only 9 out of 93 females harboured the same. None of the 83 buffaloes examined were found positive for the same.
Through 964 autopsies taken up in 34 poultry farms around Dharmapuri, it was revealed that the ceacal form of Coccidiosis was more prevalent in 0-8 weeks of age and intestinal form of coccidiosis was more during maturity time i.e., start of lay.
Deworming of sheep (Trichy Black breed) with 1% copper sulphate at an interval of 45 days increased the survivability (3%) and increased the weight gain (3%), as compared to the control group.
From 54 mastitic milk samples collected and tested, it was found that 43.6% of the cases were due to mixed bacterial infections and high incidence was due to Staphylococcal species (70.8%).
The efficacy of 13 different antimicrobial viz:Amikacin, Amoxycillin, Cehapaexin, Chloramphenicol, Cirpfloxacin, Cloxacillin, Co-trimaxazole, Eoxycycline, Gentamicin, Norfloxacin, Penicillin, Streptomycin, and Tertracycline, were tested in vitro against 54 masititis milk samples. The pathogens were highly sensitive to Amikacin (77.8%), Gentamycin (77.8%), Gentamicin (77.8%), Ciprofloxacin (72.2%), moderately sensitive to Cephalexin (63.9%), Doxycycline (61.1%) and Chloramphenicol (58.3%), and less sensitive to Tertracycline (44.4%), Pencillin (27.18%), Amoxycillin (25.0%), Cotrimaxazole (22.2%) and Cloxacillin (11.1%).
Post mortem conducted on 513 birds during 1998-99, revealed that the higher incidence was seen in Gumboro disease (46.6%), followed by Ranikhet disease (31.6%), Colibacillosis (13.8%), and Mycoplasmosis (9.8%).
Dung samples of sheep (2584) were examined to identify different oocysts and larvae of helminthic parasites. It was found that 96.4% of cases were infected with trichostronglyes oocysts and larvae of intestinal parasites.
Qualitative water analysis done on 138 water samples revealed that 91.8% samples had chlorides, 1% of samples contained nitrites and nitrates and traces of phosphates and ammonia were present in 14.7% and 3.6% samples respectively.
Gliricidia leaf meal with 18.06% crudeprotein seemed to be a good protein source for poultry ration. The inclusion of gliricidia leaf meal at 5% in cockerel / broiler ration replacing a mixture containing sunflower oil cake (34%) de-oiled rice bran (66%) seems to beneficial.
An epidemiological study on the prevalence of various helminthic parasites of Macheri, Trichy black and Mandya sheep was carried out. Of 1112 animals examined, the overall prevalence of helminthic infection was observed to be 26.7% with strongylid nematodes predominating at 16.4%, followed by monezie sp.(3.1%), amphistomes and strongyles. Among the three breeds examined, Macheri was more susceptible to helminthic infection (28.5%).
The qualitative analyses of water samples for chemical impurities revealed that none of the samples was free from chloride impurities. Further 58%, 20%, 36%, 23% and 20% of the water samples contained ammonia, sulphate, phosphate, nitrate, nitrite respectively.
