ThesisItem Open Access Evolving low cost ration for commercial broiler rabbit production(Department of Livestock Production Management, College of Veterinary and Animal Sciences, Mannuthy, 2006) Biya Ann, Joseph; KAU; Kannan, AA study was conducted to document the present rabbit farming scenario in Thrissur district and to evolve a low cost ration for rabbits utilizing concentrates and vegetable cuttings in different ratios. The documentation was conducted on thirty rabbit farmers using a well-designed questionnaire and personal interview. The socio-economic status of the rabbit farmers and management practices were studied. The composite feed samples fed to rabbits were analysed. The rabbit farmers mostly lived in a nuclear family system and were employed either in public sector or owned business. The reason for engaging in rabbit rearing was for additional income generated and for the value of keeping rabbits as pets. Most of the farmers had only 1-6 months experience and the responsibility of rearing rested with wife and children. New Zealand White was the preferred breed and the rabbits were mostly obtained from local rabbit farmers. Most farmers maintained herd strength of less than 20. A mixture of concentrate and locally available leaves and grasses was the major feeding method with a feeding frequency of twice a day and most rabbits were fed 100-125 g ration daily. The crude protein, crude fibre and ether extract of composite rabbit feed was 15.48%, 14.98% and 1.74% respectively. Pan watering was the common method of watering. Cage system was the preferred type of housing with a cage size of 2-4 sq.ft. and 4-6 sq.ft. Majority of the cages were located adjoining the house. Most rabbits were sold at 2 months of age at Rs. 100-150 per pair. Digestive disorders were the frequently occurring disease and rabbits were mostly treated by veterinary doctors. Use of nest box, manure disposal and daily cage cleaning were the commonly adopted scientific management practices. Thirty weaned New Zealand White rabbits were selected and utilized for the study. They were divided into five groups of six animals each and allotted to one of the following treatments: T1 – Rabbits fed with the ration (100 per cent concentrate) provided by the Rabbit Research Station, Mannuthy (Control). T2 – Rabbits fed with 75 per cent concentrate and 25 per cent vegetable cuttings on Dry Matter (DM) basis. T3 - Rabbits fed with 50 per cent concentrate and 50 per cent vegetable cuttings on DM basis. T4 - Rabbits fed with 25 per cent concentrate and 75 per cent vegetable cuttings on DM basis. T5 - Rabbits fed with 100 per cent vegetable cuttings on DM basis. The parameters like fortnightly body weight, fortnightly body weight gain, average daily gain, average daily feed intake on dry and fresh matter basis, feed conversion efficiency, proximate analysis of concentrate and vegetable cuttings, occurrence of disease, carcass traits and economics of production showed significant difference between the treatments. T2 had the highest body weight among all treatments whereas T1 and T3 showed no significant weight difference and T5 had the least weight. A similar trend was seen in average fortnightly weight gain and average daily gain, with T2 having the highest gain and T5 the least gain. The daily feed intake had a linear increase from first to the sixth fortnight in all the treatment groups. The feed conversion efficiency (FCE) increases with increase in the percentage inclusion of vegetable cuttings on DM basis. Vegetable cuttings had a higher percentage moisture, crude fibre and total ash (79.63, 17.08 and 9.58) than concentrate (10.75, 4.09 and 3.57) but lower crude fat (1.75) and nitrogen free extract (50.64). The percentage crude protein content was almost similar in both concentrate (21.82) and vegetable cuttings (20.97). Digestive disorder was the commonly observed disease closely followed by mange. The dressing percentage varies from 45.31 in T5 to 52.27 in T2. The cost of production of one kg of rabbit meat ranges from Rs. 47.52 in T1 to Rs. 8.72 in T5. T2 has a higher weight and feed conversion efficiency, but the cost of production of Rs. 41.56 is high compared to T3, which is on par with T1 in weight gain and lower by Rs. 13.92 in its production cost. Hence rearing rabbits on a combination of 50% concentrate and 50% vegetable cuttings can be recommended for commercial broiler rabbit production.ThesisItem Open Access Management of captive young elephants in Kerala(Department of Livestock Production Management, College of Veterinary and Animal Sciences, Mannuthy, 2006) Acty, George; KAU; Anil, K SThe present study was undertaken to suggest suitable recommendations in the management of captive young elephants of Kerala after assessing the existing management, feeding and training practices through survey method. The credibility of information collected was cross checked with physical verification. Data was collected from the owners’ house holds and offices and sites where animal was tethered by personal interviews during March to August 2006. The observations made were on routine, housing feeding, diseases and health management, behaviour and temperament and record keeping. From the study, it was evident that majority of the elephant owners, first and second mahouts belonged to middle age groups. Even though none of the owners received training, half of the owners were richly experienced in elephant management. Majority of the owners and mahouts selected elephant rearing as hereditary business or job. Injury was a major constraint in case of mahouts. The young animals were divided in to three groups based on their age as 0- 2yrs (Group I), 2-6yrs (Group II) and 6-15yrs (Group III). Group II and III received more watering, wetting and bathing. Frequency of wetting and watering was highest in summer season. Actual training starts at 6 years of age and train the elephants for various purposes. It was evident that young elephants are fed above the nutritional requirements and kept idle for most of the time in the year. Boredom was found to be a factor for behavioural anomalies. Major ailments in young ones was diarrhoea were as impaction in adults. There was record keeping only in organized elephant care facilities.
