The average number per farm was 0.76 in Lime and 0.27 in Parkote. The average of age and parity was 8.2 years old and 4.4 in Lime, and 6.6 years old and 2.8 in Parkote, respectively. The mean dry matter (DM) supply of roughage, supplemental feed and total feed was higher in the dry season than in the rainy season (11.8 kg/head/day vs. 10.3 kg/head/day, 1.2 kg/head/day vs. 0.8 kg/head/day, 13.0 kg/head/day vs. 11.1 kg/head/day, respectively, P<0.05). Although the average DM supply of roughage per body weight (BW) and total feed supply per BW had no significant differences between the seasons, the mean DM supply of supplemental feed per BW was higher in the dry season than in the rainy season (0.35% of BW vs. 0.22% of BW, P<0.01). The BW, heart girth (HG) and hip born width (HW) of Parkote were higher than those of Lime (401.7 kg vs. 368.0 kg, 185.7 cm vs. 179.8 cm, 50.4 cm vs. 48.4 cm, respectively, P<0.05). However, the body length, wither height (WH) and criss-cross height showed no significant differences between Lime and Parkote (127.4 cm and 129.8 cm, 118.7 cm and 119.5 cm, 118.0 cm and 119.4 cm, respectively). The BW estimation using body dimensions may play a significant role to know about the buffalo body condition. With the measured BW, HG, WH and HW in this survey, the formulae to estimate BW of Lime and Parkote buffaloes were established.

Thus, further development of dairy buffalo is required for efficient production. However, the changes of milk production and reproductive performance of buffaloes in the country remain obscure. Hence, the study is conducted for identifying the dairy production and reproduction of buffaloes raised in Nepal during 15 years. The records of daily milk yield (MY) from July 1997 to July 2012 were collected at Livestock Development Farm, Nepal. Lactation MY, 305 days MY, lactation length, MY per day of lactation, peak MY, days to attain peak MY, calving interval and dry period were calculated. The results were summarized every 5 years (

During the study, 162 goat farms located in Ghiring and Baradi of Tanahun districts in Nepal were surveyed, and a semi-structured questionnaire was administered to each farm. Farmers in this region prefer integrating livestock raising with crop production. The majority of the farms surveyed kept indigenous Khari goats, either in pure flocks or through crossbreeding. The types of goat farming were commercial (8.02%), semi-commercial (29.01%) and subsistence (62.96%). The nature of management practices for goat farmers was intensive (70.99%), semi-intensive (14.81%) and free range (14.20%). Farmers grazed their livestock in different locations, including their own land (48.77%), forests (22.22%), and other places (29.01%). The selection of fodder species by farmers varied depending on the availability of different species in the mid hills, reflecting differences in ...

The FGF5 gene is a regulator in the hair-growth and a SNP c.-253G>A located within 5'UTR has been reported to cause long-haired phenotype. The EPAS1 gene is a transcription factor for various genes that have hypoxia-adaptive functions and a nonsynonymous SNP (Q579L) located in exon 5 has been reported to be associated with the mean corpuscular hemoglobin concentration. Nepal has large difference in altitudes in the north-south direction and four indigenous goat breeds are bred depending on the altitude. We used a total of 130 animals in Nepal, Chyangra (n = 37), Sinhal (n = 24), Khari (n = 33), and Terai (n = 36), and genotyped these two gene polymorphisms to compare the gene frequencies among the breeds and investigate the associations between breeding altitudes and allele frequencies. The genotyping results revealed that the mutant allele frequency in both polymorphisms tended to increase, as the breeding altitude of each population increased. In addition, correlation coefficients showed a relatively strong positive correlation between the breeding altitude and the mutant allele frequencies (r = 0.87 in FGF5 and r = 0.68 in EPAS1). These results suggested that both polymorphisms would significantly contribute to the high-altitude adaptation in Nepalese goat breeds.

The study was conducted in four altitudinal gradients viz. <400m, 400-800m, 800-1200m and 1200–1600m altitude above sea level in different looping seasons: rainy, spring and winter seasons. The most important five species of fodder trees Artocarpus lakoocha, Ficus roxburghii, Thysanolaena maxima, Ficus semicordata and Bauhinia purpurea were selected based on farmers’ preferences in nutritional values. Fodder samples comprised young leaves, old leaves and young twigs that were taken in July, September and December. It was revealed that nutritive value is not very much influenced by altitude but it is strongly influenced by lopping seasons. Among Thysanolaena maxima, Artocarpus lakoocha, Ficus roxburghii and Bauhinia purpurea the cellulose contents were significantly different (p<0.001) with seasons but there was no ...

In the mid hills of Nepal, farmers generally practice integrated farming system that combines crop cultivation with livestock husbandry and agroforestry. Tree fodders are good sources of protein during the forage and green grass scarcity periods especially in dry season. Local communities possess indigenous knowledge for the selection of grasses and tree fodders at different seasons in mid hills of western Nepal. A study was conducted on the perception of farmers with respect to selection of fodder species in eight clusters in Kaski and Lumjung districts that range 900-2000 meter above sea level and receive average precipitation of 2000- 4500mm per annum. During the fodder preference ranking, farmers prepared the inventory of fodders found around the villages and nearby forests and selected top ten most important fodders in terms of their availability, palatability, fodder yield, milk yield and milk fat yield. In total...

Stall feeding of buffalo is common in Chitwan with occasional grazing. This raises questions about status of nutrients supplied to maintain productivity as feed resources varied in forest and crop land according to the season. A study was carried out in Chitwan from April 2015 to March 2016 to find out the status of nutrient supply in relation to the feeding system of buffalo. Total fifteen farms were selected from three villages, the amount of feedstuff fed to the animals was measured every month and the nutrient contents of the feed were analyzed. The mean concentrations of DM, CP, TDN, Ca and P were 641g/kg, 75.0 g/kg, 462 g/kg, 4.9 g/kg and 4.2 g/kg. A significant difference of CP contents among the villages was observed (72.0 g/kg, 70.7 g/kg and 81.2 g/kg (P<0.01), and the highest content of CP, TDN, Ca and P were found in July (P<0.05)). The study showed vari...
