- PublicationSUBCLINICAL COCCIDIOSIS IN ANGORA RABBITS, A FIELD SURVEY IN HIMACHAL PRADESH, INDIA(World Rabbit Science. ICTA. UPV, 1996) JlTHENDRAN, K.P.; BHAT, T.K.[EN] Eight species of coccidia were identified in 180 (57.3%) out of 314 faecal samples or topotypes from four commercial rabbitries in Kangra Valley of Himachal Pradesh. Mixed infections were common and 82% of thé infectad animals harbored 2-4 Eimería species. Eimeria magna, E eertorans and E media were the predominant species whtle E. i"esidua, E. stiedai and E intestina/is were less common, and E. piriformis and E. coecicola were relatively rare. E. exigua, E. flavescens and E. vejdovskyi were not recordad in lhe present study. The level of mfection basad on the oocyst output data, was found to be relatad to management practicas. The intensity of infection assessed by oocyst par gram of faeces (OPG) was higher in big prívate - farms (0.05 - 80 x 103) in comparison to small Govemment farms (0.3 - 16.5 x 103).
- PublicationRABBIT COCCIDIOSIS AND ITS CONTROL : A REVIEW(World Rabbit Science. ICTA. UPV, 1996) BHAT, T.K.; JlTHENDRAN, K.P.; KURADE, N.P.[EN] Coccidiosis causad by Eimeria species, is a majar parasitic disease of rabbits and is responsible for a high incidence of morbidity and mortalitv. The incidence of th1s disease in EuroP.ean countries in 21-60% and in India 13-64%. In commercially rearad rabbits; coccidiosis occurs .in a subclinical form witti growth retardation and alterad feed conversion. The disease occurs in two forms, hepatic and intestinal, the latter being more common than the formar. Presently, the control of rabbit coccidiosis relies almost entirely on chemical coccidiostats. However, extensiva use of such arugs in commercial rabbitries has already started creating problems of drug resistance. In view of the limitations of chemotherapy, it is imperativa to develop immunoprophylactic measures against rabbit coccidiosis. These incluae development of live-attenuated and recombinant vaccines against the parasite.
- PublicationGROWTH PERFORMANCE OF BROILER RABBITS MAINTAINED ON DIFFERENT DIETS(World Rabbit Science. ICTA. UPV, 1996) Prasad, R.; Singh, G.; Patnayak, B.C.[EN] A study on growth ferfonnance on 90 broiler rabbits of White Giant and Sovie Chinchilla, weaned a 28 days and malntained on 3 different diets for 56 days, was conducted with an objective to work out an economical feeding s~tem. First group (T1) was provided concentrate pellets and co~ea hay (Vigna sinens1s) plus green alfalfa, second ~oup (T2) ad libitum complete pelleted raed and third group 3) was provided ad libitum concentrate pellet alongwit green alfalfa fodder. Dry matter intake in T3 was (139g/d) significantly (P<0.01) higher than that of T1 (106g/d) and T2 (97 g/d), the latter two, however did not dlffer significantly from each other. The average daily gain in T2 ~30 ~R and T3 (29 g/d) were significantfy hlgher fhan In T1 24 ó/d . The highest net return per rabbit was recordad in T2 Rs ~. m followed by T3 (Rs 6.21) comparad to T1 (Rs - .88). The results tend to conclude that the economlcal weight gain of about 30a/d under tropical conditlons can be ach1evea in exotic farm 6red broiler rábbits maintained either on complete pelleted feed or concentrate pellets supplemented with good quality green alfalfa, fed ad libitum.
- PublicationEFFECT OF IVERMECTIN AGAINST EAR MANGE MITE (Psoroptes cuniculi) IN NATURALLY INFESTED RABBITS(World Rabbit Science. ICTA. UPV, 1996) KURADE, N.P.; BHAT, T.K.; JlTHENDRAN, K.P.[EN] Thirtv ona New Zealand White rabbits, naturally infestad with ear manga, were divided into mild, moderate, severely infestad ané:I infestad-control groups, basad on their mean lesion seora. Three anímafs were maintained as clean-control group. tvermectin was given subcutaneously to infested raobits of the 3 first groups, four times at weekly interval, at a dose level of 20lete recovery with two injections. One rabbit each from moderately and savarely infestad groups, showed persístence of mild infestation in the form of presence of parasitic eggs till 40th day post treatment. The untraatad mfested-confrol animals sliowad parsistance of infestatíon and clean-control animals remained normal throughout the perlad of study. lt was concluded that ivermectin can be usad safely, as repeated subcutaneous injections at weekly interval at a dose of 200μg/kg 'body weight, for effective control of ear manga in rabbits. The tmportance of repeated inlections of ivennectin to control ear manga in severely infestad rabbits has been díscussad.
- PublicationEFFECT OF FAT INCLUSION IN DIETS FOR RABBITS ON THE EFFICIENCY OF DIGESTIBLE ENERGY AND PROTEIN UTILIZATION(World Rabbit Science. ICTA. UPV, 1996) Fernández, C.; Fraga, M.J.; Ministerio de Educación y Ciencia[EN] Two hundred ten Californian x New Zealand White rabbits (117 males, 93 females) were usad to study the influence of diet, slaughter weight (2.0, 2.25, and 2.5 kg), and sex on the efflciency of dietary digestible energy (DE) and protein (DCPl utilization determineáby using the comparativa Slaughter technique. Seven diets were formulated to have the sama ADF level (24%), diete had no added fat, diets T, O, and S contained 3% of added beef tallow, oleins, and soybean oil, respectively. Diets iWS, OWS, and SWS contained the sama level and types of fat than diets T, O, and S but included also a 18% of toasted whole soybeans to increase dietary ether extract (EE) by 3%. Neither fat addition nor slaughter weight influenced DE efficiency, but when the dietary EE level and the weight at slaughter were increased, DCP efficiency increased (P<0.001) and decreased (P<0.05), respectively. Females had a greater DE and a lower DCP efficiencies (P<0.01) than mares. Diets containing soyl;>ean oíl showed a higher DE efficiency than those containing oleins.
