    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. PRASANNA
    The 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.

    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, V
    A 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.

    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. WAGHMARE
    Present 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.

    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. Results of the experiment-I indicated significant influence on body weight, feed conversion ratio, Livability, Litter quality and working time measurement. However, there was no significant effect on age at sexual maturity, egg quality, per cent settable eggs, fertility, hatchability and chick quality of HH-260 birds. These results indicated that automation

    PERFORMANCE OF DEONI CATTLE UNDER FIELD CONDITIONS IN BIDAR DISTRICT
    (KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-01) AMBIKA; Dr. PRASHANT G. WAGHMARE
    The present study was conducted on 123 lactating Deoni cows in 13 villages of Bidar district. A baseline survey was carried out to identify Deoni animals being reared by farmers in the breeding tract of Deoni cattle in the state of Karnataka. Season of calving was recorded as summer (March to June), rainy (July to October) and winter (November to February). Cows were divided based on age group, parity and season of calving to study the effect of each on lactation performance and milk composition. A milk sample of 50 ml was collected from each animal. The sample was analysed for the milk composition and to conduct California Mastitis Test (CMT), Mastrip test, Electrical Conductivity test (EC) and Somatic Cell Count. On analysis it was found that season had significant effect on Lactation Milk Yield (LMY), Lactation Length (LL), Peak Yield (PY), fat, protein, lactose, and salt. Age group had significant effect on PY, fat, SNF, lactose, salt. Parity had significant effect on LL, PY, SNF, protein lactose, salt. The overall mean values were estimated to be LMY 966.08 ± 35.915 kg, LL 259.15 ± 4.883 days, PY 5.69 ± 0.176 kg, fat 4.492 ± 0.0233%, SNF 8.181 ± 0.0117%, protein 3.156 ± 0.0073%, lactose 4.410 ± 0.0112% and salt 0.6374 ± 0.00176%. The overall incidence of SCM was found to be 21.60 per cent. Mastrip test was found to be a rapid and efficient technique to detect SCM in Deoni cattle under field conditions
