ThesisItem Open Access PERFORMANCE OF DAIRY COWS FED WITH FEED ADDITIVES CONTAINING PROBIOTICS, ENZYMES AND ORGANIC ACIDS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, NANDINAGAR, BIDAR – 585 401, 2021) MD MASOOD KHAN DURRANI; S.B. PRASANNAThe present study was designed to evaluate the effect of feeding a combination of feed additives viz., probiotics, enzymes and organic acids on the performance of crossbred HF milking cows on milk yield, milk composition, rumen microflora changes and Body Condition Score of dairy cows. The cows were selected and divided into three treatment groups viz., T1 (control), T2 (single dose) and T3 (double dose) based on average previous month milk yield and stage of lactation. The results revealed that there was a significant (P ≤ 0.01) increase in the milk yield in group T2. Further among two experimental groups T2 and T3 there was no significant effect on the milk composition. On both the 30th and 60th day, there was an increase in the protozoan motility in groups T2 and T3 as compared to T1. Similarly, on the 30th and 60th day, there was a significant increase (P ≤ 0.01) in the bacterial count per 100 micro liters of rumen fluids in groups T2 and T3. There was no significant effect on rumen motility. The results of body condition score of all the animals in their respective groups were analyzed and it was found that there is no significant change in the body condition scores. The present study revealed that supplementing feed additives at a single dose (T2) level of 2ml /kg in concentrate feed (10ml/day) and 1 ml per kg of drinking water (30ml/day) is having the beneficial effect of 9.76% increase in milk yield or increase of 0.54 liter of milk per day per cow. Further, addition of feed additives in twice the dose (T3) had no beneficial effect on the milk yield or composition. Keywords: Feed additives, probiotics, enzymes, organic acids, feed additives, microflora, BCS.ThesisItem Open Access EFFECT OF VARIOUS HERBAL AGENTS AS POST MILKING TEAT DIPS ON BACTERIAL LOAD, SOMATIC CELL COUNT AND MILK COMPOSITION IN LACTATING DAIRY CATTLE(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-03) DEEPTHI, V.; MALATHI, VA study was conducted to evaluate the efficacy of various herbal agents as post milking teat dips on bacterial load, somatic cell count, milk yield and milk composition and teat condition score in lactating dairy cattle for 28 days period. A total of 25 lactating dairy HF crossbred cows of 6-8 years age were divided in to five groups each having five cows; T1 (Control fresh clean water), T2 (one per cent potassium iodide), T3 (Aloe vera gel), T4 (turmeric paste) and T5 (neem oil). Among the treatment groups, group dipped with Aloe vera gel and neem oil was significantly (P≤0.05) effective in reducing somatic cell counts, milk pH and teat skin condition score and increasing the per cent of milk compositional parameters viz., SNF, lactose and protein. Milk fat was significantly (P≤0.05) lower in group dipped with neem oil on day 28. Bacterial counts (log10) of Staphylococcus and E. coli (CFU/ml) were significantly (P≤0.05) higher in control group. Counts of Staphylococcus (log10) (CFU/ml) were significantly (P≤0.05) lower in group dipped with neem oil. Counts of E. coli (log10) (CFU/ml) were significantly (P≤0.05) lower in treatment groups other than control group. There was no consistency in milk yield, though there was a significant (P≤0.05) difference on day 7 and 14. On day 21 and 28, milk yield was not affected by any of the treatments applied. No significant (P>0.05) difference was observed in teat orifice condition score and counts of Streptococcus (log10) (CFU/ml). It could be concluded among the herbal agents used, groups dipped with Aloe vera gel and neem oil performed better compared to other treatment groups. Keywords: herbal agents, bacterial load, milk yield and composition, milk pH, teat condition score.ThesisItem Open Access ADOPTION OF GOAT MANAGEMENT PRACTICES IN BIDRI GOAT FARMERS IN BIDAR DISTRICT(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-03) MAHE ANJUM; PRASHANT G. WAGHMAREPresent investigation was carried out to study goat management practices followed in Bidar district. The desired information was collected through personal interview of Bidri goat keepers by visual observations and actual measurements on various desired aspects during year 2020-21. Information related to existing Bidri goat management practices in relation to improved practices, constraints in adoption of improved practices and level of adoption was recorded from total 180 goat farmers using prepared questionnaire through well structured interview schedule. Most common housing system was semi-intensive system (46.67%) followed by extensive (40.00%) and intensive (13.33%) system. Large chunk of goat farmers (70.00%) depends only on grazing for feeding their animals followed by grazing-cum-stall feeding (15.00%) and stall-feeding (zero grazing) alone (15.00%). However, in Bidar (20.00%) significantly (p<0.05) larger number of farmers depends on group stall-feeding alone. Majority of the goat farmers (38.89%) get their animals treated by local practitioners followed by veterinary assistants (35.00%) and veterinary officers (26.11%). Feeding related constraints were most predominant type of constraints for goat farmers. Goat farmers had adoption of various scientific goat rearing practices in following descending order i.e. kid rearing (66.77%), milking (54.8%), health management (44.66%), housing (40.33%), breeding (37.11%) and feeding (34.44%) management practices. Overall adoption of scientific Bidri goat rearing practices by goat farmers was 46.37%. It can be concluded that goat farmers in Bidar district have lower adoption rate of improved practices related to feeding, breeding, housing and health management and requires interventions of professionals to provide trainings and form societies.ThesisItem Open Access COMPARATIVE STUDY OF AUTOMATION AND CONVENTIONAL SYSTEM ON PRODUCTION PERFORMANCE IN POULTRY AND DAIRY FARMS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2020-08) ABHIJEET KUMAR; Dr. S.B. PRASANNA)A study was conducted to compare the effect of automation and conventional rearing system on production performance in poultry and dairy farms.

B. PRASANNAThe growth performance of goats under different systems of rearing was studied for 13 weeks on thirty weaned local kids of 3-4 months of age and comparable body weights. Kids were randomly distributed into three groups with 10 animals in each group. Animals of T1 (Intensive system) group were fed with concentrate mixture and weighed quantity of ground nut hay, sesbania and ragi straw (ad lib). The animals in T2 (Semi intensive system) group were allowed for grazing for 6hours and in the evening provided with concentrate and roughages at the level of 50% of the requirements of T1 group. The animals in T3 (ExThesisItem Open Access A STUDY ON GROWTH PERFORMANCE OF KIDS UNDER DIFFERENT REARING SYSTEMS(KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2019-08) SUMITRA B. MALLUR; M. C. SHIVAKUMARThe present study was conducted with the objective of assessing the growth performance of local kids of Hassan district, under the intensive and semi-intensive systems of rearing, by recording the morphometric measurements and the body weights fortnightly. Similarly, the trial also aimed to analyze the influence of rearing systems on blood biochemical parameters, to study the environmental variations using ambient temperature (ºC) and Relative humidity (RH %) to arrive at THI in the study area and to evaluate the GIT parasitic load in the experiemental kids. The obtained values were analyzed statistically. The results revealed that the mean values for body weights of the kids recorded were non-significant (P>0.05) between the groups. The overall mean of the ADG (g/d) were found to be 23.72 ± 1.92 in group I and 22.74 ± 1.58 in group II, which were statistically (P>0.05) non-significant. Morphometric measurements viz., body length, height at wither and chest girth of the experiemental animals remained statistically non-significant (P>0.05) during the study. The overall incidence of the GIT parasitic load in both the rearing groups did not vary statistically (P>0.05) between the two rearing groups. Blood picture of the animals, with respect to the parameters like RBC (106 μl), Hemoglobin (g/dl), PCV (%) were found to be non-significant (P>0.05). Correspondingly, the WBC (103 μl) values remained majoritively significant (P0.05) at majority of the experiemental duration. Over all mean value of THI recorded was 85.55 ± 0.86 and 84.77 ± 1.76 during the first half (0th - 12th week) and second half (13th - 25th week) of the experiemental period, for which the animals were exposed throughout the study. Above study concluded that, rearing systems didn’t have much effect on the growth performance of present non-descript local kids. The probable reason may be due to the genetic make-up of the animals, which differs from breed to breed and variation in the agro-climatic and geographical set up from region to region.ThesisItem Open Access A STUDY ON GROWTH PERFORMANCE OF NATIVE CHICKEN UNDER INTENSIVE AND SEMI-INTENSIVE SYSTEMS OF REARING(KARNATAKA VETERINARY, ANIMAL AND FOISHERIE'S SCIENCES UNIVERSITY, BIDAR, 2019-10) LAXMESH KATTIMANI; Dr. M. C. SHIVAKUMARThe present study was conducted on 200 native chicken were distributed among intensive and semi-intensive systems of rearing (100 birds per each system) from 9th to 20th weeks of age. To study the effect of growth performance of native chicken under intensive and semi-intensive systems of rearing was taken up in the Department of Livestock Farm Complex, Veterinary College, Hassan and Yediyuru village, Hassan. respectively. Different management systems had significant (P0.05) between the two systems of rearing. The BCR was higher in semi intensive system 1.69 compared to intensive system of rearing 1.56. The average SFRB was 11.42 g/b/d observed during 9th to 20th weeks of age. The study was concluded that native chicken can be reared under intensive and semi-intensive system of management successfully. However, semi intensive system of rearing native chicken was found to be more economical than the intensive system of rearing.
