Title : Effect of forced molting on post molt production performance of locally available commercial laying chicken Material Type: printed text Authors: S. Sapkota, Author ; R. Shah, Author ; D. K. Chhetri, Author ; S.R. Barsila, Author Publication Date: 2018 Article on page: 199-204 p. Languages : English (eng) Keywords: : Forced molting, layers, post molt, mortality, feed intake Abstract: A study was done at a commercial farm in Sorabhagh, Morang district on layers using a cage system
for 114 days during June 24, 2017 to October 15, 2017. The objective of this study was to determine
the effect of forced molting on production parameters of Lohmann layers. The cages were disinfected
before the study with Virkon-s and Hydrogen peroxide. 3072 laying birds were divided into three
treatment groups.The treatments were- without feed restriction (control=T0), 7 days feed restriction
(T1
) and 15 days feed restriction (T2) which was further replicated each for four times. There were
256 birds in each replication. The mortality rates, feed intake per bird, egg production and egg weight
were recorded. Analysis of variance showed significantly (p the treatment groups during the first 15 days. Accordingly, higher mortality (1.07%) was recorded
in T2. Result revealed a significant difference in feed intake throughout the study period. In the end,
higher feed intake (102.45 g) was recorded in T2. However, statistically similar (p>0.05) feed intake
was observed in T1
and T0. The results showed a significant difference in egg production among
the treatment groups. Higher egg production (65.9%) was observed in the T2
group at the end of the
experimental period with an increasing trend. However, lower egg production (47.7%) was recorded
in T0. Statistically similar egg weight (p>0.05) was recorded in all treatment groups throughout the
study period.The results obtained from this study revealed that forced molting can increase the egg
production and feed intake rate with the cost of slight increment in the mortality rate.Link for e-copy: https://afu.edu.np/sites/default/files/Effect_of_forced_molting_on_post_molt_pro [...]

Title : Relationship between udder and teat conformations and morphometrics with milk yield in Murrah buffaloes Material Type: printed text Authors: S. P. Poudel, Author ; D. K. Chhetri, Author ; R. Sah, Author ; M. Jamarkatel, Author Publication Date: 2022 Article on page: 209-217 p. Languages : English (eng) Keywords: Conformations, milk yield, murrah, teat, udder Abstract: Udder and teat conformations and measurements play a vital role in milk productivity and mastitis resistance
in dairy buffaloes. The study was conducted on apparently healthy 24 Murrah buffaloes running on different
parities selected from 3 different farms in the Chitwan district of Nepal to find the relation between phenotypic
characteristics of udder and milk yield. The shapes of the teat and udder were evaluated by a visual appraisal
that revealed 42.7% funnel, 26% bottle, 16.7% cylindrical, 14.6% conical-shaped teats, and 37.5% round, 33.3%
bowl, and 16.7% goaty, and 12.5% stepped shaped udders. The average length, width, and depth of the udder were
determined as 54.50±0.92 cm, 19.33±0.46 cm, and 27.50±1.10 cm, respectively, while the respective length and
diameter of the teat were 8.46±0.17 cm and 3.59±0.07 cm. Within udder quarters, teat length was significantly
different (p along the teat and udder shapes showing the highest measures at bottle-shaped teats and goaty-shaped udder. The
average milk yield/day recorded was 5.90±0.36 kg per buffalo. Higher milk yield was observed in the roundshaped udder and conical-shaped teat. The correlation of udder width (r= 0.237, p p milk yield. Hence, the selection of Murrah buffaloes for milk production traits should consider the dimensions
