NETWORK PROJECT ON BUFFALO IMPROVEMENT
Salient Research Achievements
The NWP(B) was initiated in 1993 with the aim to produce progeny tested bulls for improvement in buffaloes. Seven important buffalo breeds are covered under sixteen centres and conservation of Bhadawari, Swamp and Nili-Ravi Breed is going on along with improvement.
Murrah Breed: Proven bulls - 1994 from GADVASU, Ludhiana (sire index 2487 kg) and bull no 5258 from NDRI. Karnal (sire index 2466 kg) with % superiority of 11.73 and 10.52 over contemporary daughters were used for elite mating . Semen of 14th set was used for test mating at six participating centres. Breedable buffaloes were 738 at Murrah centres. Till now 176 superior bulls were test mated in 13 sets and 12 bulls of 14th set are being used in test mating. 156487 frozen semen doses of 48 test bulls of 11th to 15th set are available at CIRB, NDRI and GADVASU. Six bulls and 68635 frozen semen doses from CIRB, 24784 frozen semen doses from GADVASU, 5 bulls and 62054 doses from NDRI were disseminated for breeding purposes. Wet average varies from 5.25 kg at SVVU, Mamnoor to 8.01 Kg at CIRB. The wet average at LUVAS centre was 9.40 Kg (n=62). The weighted Wet average was 7.73 Kg (n=404, including LUVAS buffaloes in 2013-14). Average 305 day or less day milk yield varies from 1728±158 kg (n=17) at KVASU to 2509±67 (n=55) at GADVASU. The average 305 day or less day milk yield was 2808±43 Kg at LUVAS centre, The weighted mean of average 305 day or less day milk yield was 2351 kg (n=477). There is improvement in this trait over the previous years. Weighted SP varies from 118±9 days (n=39) day at LUVAS to 322±115 days (n=6) at KVASU with the weighted mean of 155 (n=324). AFC reduced to 10 days over the previous year. The weighted mean fat was 8.00 percent in Murrah and average fat was 10.16 percent in Swamp followed by 8.65 percent in Bhadawari.
Field Units of Murrah Breed: The field progeny testing programme was initiated with the aim to produce more number of daughters per bull for evaluating sires with more accuracy. At GADVASU centre 8014 AI, 3380 PD were done, 2831 calving were recorded out of which 1303 were female. 120 daughters calved and 92 daughters’ test day milk yield recorded in the year 2013-14. At CIRB centre 3962 AI, 1933 PD were done, 1230 calving were recorded out of which 552 were female. 72 daughters calved and 50 daughters’ test day milk yield recorded in the year 2013-14. At NDRI centre 4419 AI, 1622 PD were done, 1225 calving were recorded out of which 560 were female. 354 daughters calved and 221 daughters’ test day milk yield recorded in the year 2013-14. Daughter’s records are now being used for bull evaluation.
Other breeds (Nili-Ravi, Jaffarabadi, Pandharpuri, Surti, Bhadawari and Swamp):
Nili-Ravi, Bhadawari and swamp breed centres are functioning as conservation and improvement units and Jaffarabadi, Pandharpuri and Surti breed centre are concentrating on field progeny testing along with maintaining the herd for bull production and testing. A breedable herd of 514 (Nili-Ravi-214, Jaffarabadi-138. Pandharpuri-21, Swamp-40, Surti-48 and Bhadawari-53) is being maintained at the above six breeds. Nabha centre has sold 27875 frozen semen doses to developmental agencies and farmers. It indicates increased demand of Nili Ravi semen. 305 or less day lactation milk yield was 2241 kg which is 224 kg more than the yield of 2012-13. Lactation length also improved to 285 days from 264 days in 2012-13. Annual wet average was 8.25 kg and herd average was 5.32 kg. In Jaffarabadi IInd set of bulls were used for AI at the farm and conception rate was low at 30.0%. 36177 semen doses from 10 bulls are available at the centre. During the year only 18604 doses of semen were produced and 8725 doses were used in AI in farm and field. In surti conception rate at farm was very good at 61.2 percent and 63.51 percent buffaloes were in milk. Production performance in term of lactation yield, lactation length, 305 or less day milk yield were 1527.0±49 kg, 294.0±10 days and 1481.0±38 kg, respectively. Semen from the 8 bulls were used for AI’s. 293 progenies are available in the field for recording. Recording on 33 daughters completed. The swamp breed centre is conserving the swamp buffaloes putting effort to maintain only swamp at the centre. The Bull certification laboratory is testing and screening for various diseases i.e. Tuberculosis, Johnin Disease, Brucellosis, IBRT, Leptospirosis, Campylobacteriosis and Trichomoniasis, so that disease free frozen semen doses may be provided for bull testing and dissemination.
Selection and use of Breeding Bulls for Murrah breed
From July 93 till date test mating from 14 sets of bulls have been completed and 15th set will be operational from July 2014. Brief summary of the duration, the number of bulls, their average age at the time of selection, average of the dam’s best yield and highest dam’s yield in each set is shown below.
Fifteen sets of bulls used under Network Project on Buffalo since July 1993.
* bulls from Deedwadi ** Two from Redhu Farm
List of bulls selected for 15th set (Murrah Breed)
These bulls shall be used from 1st July 2014 for test mating at Murrah centres and field units
Note : From each bull 10,000 semen doses are to be frozen. * Purchased in 2nd lactation
