ThesisItem Open Access A STUDY ON THE MANAGEMENT PRACTICES OF MALNAD GIDDA CATTLE IN SHIVAMOGGA DISTRICT WITH SPECIAL REFERENCE TO MANAGEMENT INTERVENTIONS(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2021-02-01) LOHITH J.; Y. B. RAJESHWARIThe objectives of this study was to document the existing management practices of Malnad Gidda cattle in Shivamogga district, record the performance of Malnad Gidda cows under field conditions, evaluate the constraints faced by Malnad Gidda cattle farmers, and assess the effect of strategic nutritional interventions on the productive performance of Malnad Gidda cows. The existing management practices were recorded by means of personal interview using a structured schedule, with respondents selected using a multistage stratified sampling procedure. Most farmers rearing Malnad Gidda cattle reared negligible numbers of crossbred cattle, recognised buffalo breeds, sheep, goat or poultry; thus revealing the suitability of Malnad Gidda cattle to their production system that is low input and low output system. The most common management practices were loose housing, natural service with locally available bulls, grazing during the day time and some farmers used stall feeding at night, good care and feeding practices for calves, no concentrate purchase for cows, and adequate milking techniques. The mean lactation milk yield, peak yield, lactation length, milk fat, milk SNF, age at first calving, service period, dry period, gestation period and calving interval were found to 193.74 kg, 1.68 kg, 185 days, 4.02 per cent, 8.17 per cent, 38.70 months, 169.28 days, 168.29 days, 280.45 days and 558.01 days, respectively. The major constraint categories, analysed as per Garrett”s Ranking technique, in descending order of importance, were problems in breeding, feeding problems, general problems, marketing problems, breed characteristics and health care problems. The results of a feeding trial of 12 weeks on Malnad Gidda cows revealed that though treatment group fed with CFM, body weight gain, milk yield and milk SNF yield had significant differance than those not fed CFM group that is control group. It was concluded that Malnad Gidda cattle are highly suited as a multipurpose breed for Shivamogga district and there is vast potential for improvement in the performance of the breed by means of selective breeding techniques. Efforts must be made to educate farmers regarding improved management practices like construction of proper feed mangers, regular vaccination and deworming, adequate nutrition of heifers and milking cows, and scientific waste management.ThesisItem Open Access EFFECT OF MILK REPLACER AND REARING SYSTEM ON GROWTH AND PERFORMANCE OF SHEEP(KARNATAKA VETERINARY, ANIMAL AND FISHERIES SCIENCES UNIVERSITY, BIDAR, 2019-10-10) UMESH YADAV, M.; Y.B. RAJESHWARIThe present study was undertaken to investigate effect of feeding milk replacer and system of rearing on growth and performance of local sheep (Sira strain). Forty five lambs in Phase I was equally divided in to three different treatment groups of fifteen each. T1 (EM), T2 (EM+MR) and T3 (MR). The total DMI (g/d) was significantly higher in T3 (404.11) compared to T1 (322.95). The ME intake (MJ/d) was high in T3 (3.89) compared to T1 (2.59) groups. The ADG (g) was significantly high in T2 (131.32) followed by T3 (122.22) and T1 (112.77). The FCR was better for T1 (2.86). Thirty six lambs, twelve from each treatment group of Phase-I, was divided into 2 groups of eighteen lambs each, which was reared under intensive (Group-A) and semi-intensive (Group-B) rearing system. There was no change in the body weight gain among treatment group in both system of rearing, but ADG was significantly high in lambs of T2-A followed by T3-A and T1-A.FCR was better in T3-A (5.83). There was significant difference (P<0.0001) in final body weight and ADG between system of rearing. Early weaning of lambs in T3 group shortens the inter-lambing period of ewe’s by 28-34 days. The income return was more for T1 group in Phase-I and T2-A and T3-B in Phase-II. Zero mortality was reported in both Phase-I and II. Blood parameter was within normal range in both Phase-I and II. Based on this results it was concluded that lambs can be successfully reared with milk replacer.

Based on bedding material, rabbits were divided into coconut coir group (T1), ragi straw (T2) and wire mesh group without any bedding material (T3). There was significantly (P<0.05) higher water absorption capacity in ragi straw compared to coir but there was no significant difference in moisture content between them. No significant difference was observed in the body weight of rabbits at late pregnancy, kindling or at weaning between the groups. Litter size and litter weight at birth, 7days, 14 days, 21 days or at weaning (28 days) were not significantly (P>0.05) influenced by bedding material. The average litter size and weight at weaning were 5.72±0.28 and 1488±38.73 in T1 group, 4.94±0.26 and 1202±35.45 in T2 group and 4.50±0.27 and 991±39 in T3 group respectively. The highest litter size and weight at weaning were recorded in T1 group which was significantly different (P<0.05) from other two groups. Mortality percentage up to weaning was 8.03% in coir group, 12.74% in ragi straw group while it was 23.07% in wire mesh group indicating significant difference between groups. No significant (P>0.05) difference was observed in the serum cortisol levels between groups. Significant differences were recorded in preference towards different bedding materials where rabbits spent 34.46% time on coir, 23.07% on ragi straw while it was 42.45% on wire mesh without any bedding material. The results indicate that coir can be suitably used as a low-cost bedding material alternative to ragi straw which can be utilized as a fodder source for ruminants.
