Title : Changes in physiological and metabolic parameters of sheep (Ovis aries) during trans-humance at western himlayan pastures Material Type: printed text Authors: K. Bhatta, Author ; N. R. Devkota, Author ; I. C. P. T. Tiwari, Author ; S.R. Barsila, Author Publication Date: 2018 Article on page: 171-175 p. Languages : English (eng) Keywords: Baruwal sheep, transhumance, metabolism, physiology, adaptation Abstract: Transhumance is an integral part of sheep husbandry in high mountains whereas out of total sheep
population, about 60 % are reared under the transhumance system. Transhumance Baruwal sheep
flock from the northern part of Jumla grazed at two different altitudes were selected for this research.
The main objective was to access the changes in physiological and metabolic parameters of sheep
grazed at two different altitudes along transhumance route, and to suggest appropriate husbandry
practices. This study consisted of 21 apparently healthy Baruwal sheep under transhumance which
were divided into four groups; male below 1 year (8); male above one year (5); female below one
year (5), and female above one year (2). This study was done during July 2017 to December 2017.
The herd was clinically inspected for the presence of any infection. Adaptation period was set for one
month. Blood sample was taken from selected herds at both grazing altitudes i.e. from lower stopover
Chandannath (2431m.a.s.l) to higher stopover Khali (3885 m.a.s.l). Blood glucose, albumin and total
protein (TP) were significantely (p and TP level were decreased at higher altitude as compared to low. Furthermore, altitude, age and sex
had a significant (p increase in RR and HR was observed at higher altitude. Lambs as compared to adults had higher
respiration and heart rates. Similarly, there was a higher RR and HR in ewes as compared to ram. The
study result had showed elevated level of blood biochemistry and physiological values in response
to changing environment. Finding of the study suggests reduced stress during transhumance could
ensured by slow upward movement, nutritional management, and adjusting transhumance herd to
adverse weather condition that needs to consider in transhumance sheep while addressing possible
infection and health hazard, and thereby increasing production from herd.Link for e-copy: https://afu.edu.np/sites/default/files/Changes_in_physiological_and_metabolic_pa [...]

Title : Different seed rates of forage maize with a fixed stand of cowpea affects proximate composition of both species Material Type: printed text Authors: S.R. Barsila, Author Publication Date: 2020 Article on page: 255-259 np. Languages : English (eng) Keywords: Harvesting, Intercropping, Maize-Cowpea, chemical composition Abstract: Mixed cultivation of fodder maize (Zea mays) and cowpea (Vigna unguiculata) is popular due to their fast-growing, high
biomass yielding, high palatable, and mutualistic growing behavior. Evaluation of status of chemical composition of these
mixed stands grown with different seed rates of maize, but with a fixed stand of cowpea would suggest the best period of
forage harvesting and also the appropriate seed rate. Accordingly an experiment was done by following standard agronomic
practices to grow maize-cowpea at Agriculture and Forestry University (AFU) Rampur, Nepal during May to September
2016. The experiment was done by using randomized complete block design (RCBD) consisting of 4 treatments, T1
(40kg/
ha maize seed), T2
(50kg/ha maize seed), T3
(30kg/ha maize seed) and T4
(40kg/ha maize seed + weeding) along with 20
kg/ha of cowpea seed for each treatment, and 5 replications, under a similar rate of chemical fertilizer. Samples were tested
for proximate analysis at Animal Nutrition laboratory of AFU. A highly significant result was obtained among different
treatments for crude fibre, crude protein, and ash content while ether extract content was statistically similar among the
treatments in both the harvests. Maximum ash (10.94%) and crude fibre (31.24%) content were obtained in T1
on maize
stem, and higher crude protein (CP) (28.09%) content was obtained in T3
on cowpea that was similar with T2
on cowpea
for CP content at 45 days after sowing. At 75 days after sowing, higher crude fibre (CF) (35.87%) content was obtained for
treatment T4 on maize stem. Research results suggested that harvesting of maize is suitable at 45 days after sowing (DAS) if
higher ash and crude fibre requirement for balanced feed is expected to meet by using 40 kg seed rate of maize/ha whereas
harvesting of cowpea at 75 DAS would be more appropriate if highest crude protein content is expected to harvest, but it
would be possible to attain at the cost of higher crude fiber content. Nevertheless results clearly indicated that inclusion of
fodder cowpea as a legume component in a fodder stand, such as maize could be helpful for a persistent nutritive value during
later stage of harvesting.Link for e-copy: https://afu.edu.np/sites/default/files/Different%20seed%20rates%20of%20forage%20 [...]

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 : Productivity and chemical composition of oat-legumes mixtures and legume monoculture in southern subtropical plains, Nepal Material Type: printed text Authors: S. Dangi, Author ; N. R. Devkota, Author ; S.R. Barsila, Author Publication Date: 2018 Article on page: 191-198 p. Languages : English (eng) Keywords: herbage productivity, oats, vetch, pea, nutritive value Abstract: Oat (Avena sativa L.) is grown in Nepal for last hundred years; though its production potential is yet
to be explored to combat the winter forage scarcity. The oats can be grown in combination with other
fodder legumes such as berseem, lucerne, pea, and vetch. In order to increase productivity per unit
area, there is a need to test the promising forage species having high forage yield potential and quality
as well the compatibility for mix cropping. This study was designed to determine the productive
potential of oat combined with promising legumes in terms of dry matter and chemical composition.
A field experiment was done at AFU livestock farm to determine the dry matter productivity and the
chemical composition of oat (Avena sative, variety Netra) +vetch (Vicia sativa), oat and pea (Pisum
sativum), pea and vetch monoculture, respectively, and were replicated four times in field plots with
6× 6 m2
by following RCB design. Individual plots was prepared by plowing the field prior to sowing
the seeds and further, the standard agronomic practices was followed to establish the forage stands.
The forage mixture, harvesting time and their interaction were considered as major factors of analysis
for dry matter productivity and chemical constituents such as CP, CF and EE. Results showed that only
harvesting time had a significant effect (p mixture and interaction had a significant effect on legume branches. Both the harvesting time and
forage mixture had a significant effect on forage dry matter productivity (p dry matter yield was obtained from oats and pea combination (0.89t/ha), or oats and vetch (0.86t/ha).
There was a significant variation in CP, and CF content across the harvest regimes. This study results
had shown that oats-legume mixture would have the potential to increase herbage productivity and
this practice can be established in abandoned lands with minimum tillage. Oats in combination with
pea, and, or vetch could be a potential model of intercropping to attain an increased forage DM that
could be successfully extrapolated at farmers' field.Link for e-copy: https://afu.edu.np/sites/default/files/Productivity_and_chemical_composition_of_ [...]
