Abstract: Livestock is an integral part for the most rural livelihoods in Nepal. A very high proportion of poor and marginalized farmers depend on livestock as main or supplemental resources for their income. Cattle and buffalo contribute to more than 70% of the livestock sector. The Lime, Parkote and Gaddi are the indigenous buffalo breeds of Nepal. The productive and reproductive performances of indigenous buffalo breeds, Lime and Parkote, were studied in Regional Agricultural Research Station (RARS), Lumle in Nepal. The lactation data of the indigenous buffaloes recorded by RARS livestock farm for 14 years (from 2000 to 2014) was collected and analyzed to assess the production and reproduction traits. The productive performance was 964.0±33.0 litre/lactation in Lime and 878.5±66.3 litre/lactation in Parkote, while a daily milk yield of Lime was 3.2±0.1 litre/day and that of Parkote was 2.9±0.2 litre/day. The milk constituents of Lime were 9.0% fat, 9.2% solids not fat (SNF) and 3.8% protein. The milk contents of Parkote were 8.9% fat, 9.8% SNF and 4.0% protein. The maximum mating was found in October (30%), while the minimum mating was in June (1%) in both the breeds. The calving time of Lime and Parkote was maximum in September (36%). The Lime and Parkote buffaloes are high potential milking animals in the western hills of Nepal. Furthermore, the value chain and organic production approaches would be very useful for the conservation and utilization of these indigenous buffaloes.

Abstract: The objective of this study was to investigate the effect of the previous calving intervals (CI) on milk yield (MY) in the current lactation for the Italian buffalo breed population.

Data for 86,585 lactation records from the Italian Buffalo Breeders Association database, were analyzed. MY BLUP-estimates were obtained by including in the Animal Model the fixed effects of age-parity, previous CI, and herd-contemporary-group. The MY solutions for the months of CI were analyzed with the linear regression model where CI in months was the explanatory variable. 59.66% of the lactation records had CI between 11 and 14 months. 37.91 % of the lactation records were distributed between 15 and 24 months. The smaller percentage of records showed CI greater than 24 months. This CI distribution may be, in part, the result of herd management strategies. Dairy producers try to shorten the CI of their herd in order to get the most profit from early conceptions of the buffalo. The regression model and its parameters were statistically significant. The coefficient of determination was equal to 0.58. The intercept was equal to 72.42 kg; and the linear coefficient (b) was equal to -3.43. The negative value of b denotes a negative effect of CI on MY. This result indicates that there is a negative linear relationship between previous CI and MY in the current lactation. Therefore, shorten the CI may increase the profits of the farm through higher MY, because it has less of a negative effect on MY than longer CI.
