Title : Comparative performance of soviet chinchilla and californian hyline in western hills of Nepal Material Type: printed text Authors: P. B. Chapagain, Author ; M.P Sharma, Author ; M. Sapkota, Author ; N Bhattarai, Author ; M.K Shah, Author Pagination: 271-282 p. Languages : English (eng) Abstract: Data recorded at the Livestock Research Farm of Regional Agricultural Research Station, Lumle from 2001 to 2009 were analyzed using the statistical package Harvey (1990) with the objective to identify the best compatible genotypes of rabbit in terms of productive and reproductive performances considering non-genetic factors. The litter size at birth, weaning and twelfth week was significantly (p<0.001) affected by the year of kindling and breed. Similarly, the litter weight at birth (LWB), weaning and twelfth week was significantly (p<0.001) affected by the year of kindling and breed. Analysis also showed that individual weight at birth was significantly (p<0.001) affected by the year of kindling and breed. Accordingly, individual weight at weaning (IWW) was found insignificant, but significantly (p<0.001) affected by the breed. Individual weight at twelfth week (IWT) was found significantly (p<0.001) affected by year of kindling, whereas, individual weight at twelfth week (IWT) was found insignificant by the breed. Gestation length (GL) was significantly affected by year and breed (p<0.001). The overall least square mean and standard error for gestation length was 30.74 ± 0.05 days.

Title : Performance Study of Native Terai and Barbari Goats at Rars, Nepalgunj Material Type: printed text Authors: N. L. Tamrakar, Author ; P. B. Chapagain, Author Pagination: 193-196 p. Languages : English (eng) Abstract: Goats are multipwpose domesticated small ruminants reared in agro-ecological zones of Nepal
and are primarily kept for meat production. Mature 20 female Barbari and 24 Terai goats
maintained at RARS. Nepalgunj were studied to evaluate the productive performances of native
Terai and Barbari goats. The results of two years data showed that the live weight of Barbari
and local adult goats were similar (Barbari: 30.0±0.05 kg and the Terai goat: 29.3±0.33 kg).
The production performance in terms of weaning weight of male and female Terai goat were
7.90±0.82 Kg and 7. 79±0. 76 kg. For Barbari the corresponding values were 6.08±0.43 kg and
6.23±0.41 kg. The pre-weaning weight of Barbari and Terai goats was .79.9±5.55 glday and
7 4. 9±6. 57 glday respectively. The average litter size in number at birth was I. 49±0.19 in
Barbari and 1.52±0.02 in Terai goats. The litter weight at weaning was 7.84±0.54 kg in Terai
goat and 6.15±0.29 kg in Bm·bari goats. The gestation period of Barbari goat and Terai goat
were 152±1.94 days and 149.9±1.3 days respectively. The birth percentage of singlet of the
Terai goat (29.8%) was slightly higher than the Barbari goats (25.3%). Twins were similar
between Barbari (65.3%) and the Terai goats (66.2%) where as birth percentage of triplets of
the Bar_bari (18. 7%) was higher than the Terai goats (8.1 0%). The kidding rate between the
Barba~z (160%) and the Terai goat (1 63%) were found to be similar. Mortality rate in Terai
goat kzds was 21.6% where as in the Barbai adult it was about 9.02%.Link for e-copy: http://elibrary.narc.gov.np/?r=404 Performance Study of Native Terai and Barbari Goats at Rars, Nepalgunj [printed text] / N. L. Tamrakar, Author ; P. B. Chapagain, Author . - [s.d.] . - 193-196 p.

Title : Productive and reproductive performance of high grade jersey cattle in RARS, Lumle Farm Material Type: printed text Authors: B,R Acharya, Author ; M.K Shah, Author ; Shrestha, Y.K., Author ; K.P Dhungana, Author ; P. B. Chapagain, Author Pagination: 233-237 p. Languages : English (eng) Abstract: The productive and reproductive performances of high grade Jersey cattle were studied in livestock farm of Regional Agriculture Research Station, Lumle. The cattle had been maintained on-station with basal diet of commercial feed, locally available grass and a supplementary grazing for 3 hours per day. A total of 57 full lactation records from 20 cows spread over 11 years were used for this study. Productive and reproductive performance records of the animals - age at first mating, age at first calving, gestation periods, calving interval, lactation length, dry period, lactation yield and peak yield were recorded as per the standard format. The age at first mating, age at first calving, calving interval, gestation period and calf birth weight were found to be 684.4±20.5 days, 989.7±25 days, 399.5±15.3 days, 278.65±0.78 days and 22.114±0.39 kg, respectively. The sex ratios of calves produced were 56% male and 44% female. The conception rate of artificial insemination (AI) was 70.18% in the first insemination. The major mating months were Asar (June-July) and Kartik (October- November) and calving months were Shrawan (July-August) and Chaitra (March-April) with 15.79, 15.79, 14.04 and 17.54% mating and calving on these months, respectively. The average lactation yield, average daily milk yield, peak milk yield, days to peak milk yield, lactation length and dry period were found to be 2386.7±91.2 lit, 6.9±0.23 lit, 12.06±0.38 lit, 38.47±5.02 days, 349.63±9.42 days and 47.26±8.21 days, respectively. The correlation between first lactation milk yield and second lactation was found to be 0.492 (P<0.074) and second and third lactation 0.677 (P<0.065).
