Abstract : Factors Affecting Performance of Indian Murrah Buffalo: A Review
|
|
Abstract: Murrah is one of the best buffalo breed in India. The success of Indian dairy industry is much dependent on productivity and efficient reproduction performance of Murrah buffaloes. The environmental factors are generally influenced the Murrahs' performance as well as other breeds. The performance traits reviewed were first lactation 305-days or less milk yield, first lactation length, first lactation average daily milk yield, dry period, growth, age at first calving, first service period, calving interval, age at maturity, age at calving, days to first service, number of services per conception, breeding interval, breeding efficiency, conception rate and daughter pregnancy rate of Murrah buffalo. All the productive and reproductive traits were affected by herd, year and season of calving.

Abstract : Arthrodesis of a Distal Interphalangeal Joint in a wild African Buffalo (Syncerus caffer)
|
|
Abstract: Intensification of wild ruminants has resulted in more lameness cases that are presented for medical and surgical intervention. Claw problems in these wild and often dangerous animals, although similar to those seen in domestic bovines often require quick decisions and speedy adaptations of generally accepted treatment and procedure protocols. The arthrodesis of the pedal joint in a buffalo cow is one such example. Keywords: Wild, ruminant, claw, fusion, stability.Download Full Article |
Abstract : Haematological Profiles of Lactating Nili-Ravi Buffaloes Under Heat Stress-Alleviated Conditions During Sub-tropical Summer Season
|

Abstract: The experiment was conducted using forty two Nili-Ravi lactating buffaloes of Central Institute for Research on Buffaloes, Regional Station-Bir Dosanjh, Nabha, Patiala, Punjab to investigate the effect of heat stress-alleviated conditions on haematological profile in Nili-Ravi buffaloes during hot-dry (HD) and hot-humid (HH) season. All buffaloes were uniformly divided into two groups of twenty one in each group considering their lactation number, stage of lactation, body weight, dam’s milk yield and milk yield in current lactation. Out of which ten buffaloes from each group were selected for blood sampling considering those above factors. The control (T0) group were kept in a separate shed without any extra nutrient supplementation and modification in microclimate and management. The treatment (T1) group was supplemented with niacin@6 gm/buffalo/day, yeast@10 gm/buffalo/day and mustard oil @150gms/buffalo/day. They were provided curtains and mist fans in the shed. Feeding time, frequency and type of ration were also altered. During HD period, T0 group exhibited higher (P<0.002, P<0.05) WBC (17.2 x 109 /L), and lymphocyte (12.52 x 109 /L) counts and lymphocyte per cent (69.46 %) than T1 group (12.32 x 10 9 /L, 7.32 x 10 9 /L and 59.68%, respectively). Similar results were recorded during hot humid season in T0 and T1 group. The neutrophil per cent differed significantly between T0 and T1 group under HD (P<0.001) and HH (P<0.006) season. The study indicated that heat stress during sub-tropical summer months affected the haematology of lactating buffaloes and the stress could be reduced through the change (use of fans and curtains, nutritional supplementations, and feeding alterations together in the form of one package) of microclimate.

Abstract : Prevalence of Serum Antibodies against Six Leptospira Serovars in Buffaloes in Tabriz, Northwestern Iran
|
|
Abstract: Leptospirosis is an important zoonotic infectious and its prevalence is unknown in buffalo in Iran particularly in Tabriz, northwest of the country. To survey the prevalence of Leptospira infection in buffaloes in Tabriz, blood samples were collected from 85 female buffaloes slaughtered in Tabriz industrial slaughterhouse from December 2008 to November 2009. Sera were stored at -20°C until they were examined. Sera were initially screened at serum dilution of 1:100 against six live antigens of Leptospira interrogans, Pomona, Canicola, Hardjo, Ballum, Icterohaemorrhagiae and Grippotyphosa by using the microscopic agglutination test (MAT).The samples were considered positive if 50% or more of agglutination of leptospire in a dilution tests serum of l:100 were observed. 30 serums (35.29%) at dilution 1:100 were positive against 1 or 2 of serovars. the highest prevalent serovar in buffalo was Grippotyphosa (51.3%), and fallowed whit Pomona (29.7%), canicola (10.8%) and Icterohaemorrhagiae (8.1%). All of the samples were seronegative for serovar Ballum and Hardjo. Statistical analysis of the results showed that the rates of the infection in the autumn-winter and spring–summer didn’t have significant difference (p > 0/05). The rate of the infection has been statistically increased with the aging (p<0/05) and the animals with 3 and 4 pair’s permanent teeth had the highest infection rates. The serological infection rate in buffaloes in Tabriz is relatively high and it appears that it is because of living type of buffaloes in water and swamp, thus consequently the preventive methods must be applied to control of the disease.
