Title : Evaluation of egg laying and egg quality parameters of local chicken sakini (Gallus gallus domesticus) of Nepal Material Type: printed text Authors: S. Sapkota, Author ; M. R. Kolakshyapati, Author ; N. R. Devkota, Author ; N. A. Gorkhali, Author ; N. Bhattarai, Author Publication Date: 2017 Article on page: 181-188 p. Languages : English (eng) Keywords: egg, native, breed, quality, value Abstract: Eggs are the important and easy sources of protein for the people of rural areas. Moreover, eggs
from local chickens are popular and fetch good value. Therefore, this study mainly aimed at
evaluating egg laying and egg quality parameters of Sakini (Gallus gallus domesticus) of Nepal to
understand the reproductive fitness of the chicken and correlation among the parameters. For this,
a total of 30 eggs (10 each) collected from the chickens of three agro-ecological zones (AEZs),
representing terai, mid-hill and high-hill and of similar age groups after one month of egg laying.
These chickens were raised in same environment and management condition at Swine and Avian
Research Program(SARP), Khumaltar. Egg laying per hen per year was calculated for the chicken
from each AEZs and was found highest for high hills (140). Egg weight (EW), Egg Length (EL),
Egg Breadth (EB), Yolk weight (YW), Shell Thickness (ST), Dry Shell weight (DSW), Albumen
weight (AW) were the parameters recorded. With this, Least square means and Standard Errors
(LSM±SE) for Egg volume (EV), Surface Area (SA), Shape Index (SI) and Breaking Strength
(BS) were calculated. In all cases, the eggs from the Sakini from high hills were better in terms of
EW(47.45g), YW(13.6g) and AW (29.28g). Similarly, EV (42.02 cm3 ), SA(73.06 cm2 ), SI(0.75)
and BS(1718.74g) were also higher for the eggs from high hill chickens. This result showed that
the Sakini from high hills can be selected and their genetic potentiality of egg laying and egg
parameters can be explored to improve the native Sakini breeds in the other regions, of Nepal.Link for e-copy: https://afu.edu.np/sites/default/files/Evaluation_of_egg_laying_and_egg_quality_ [...]

Title : Evaluation of reproductive performance and litter traits of Khari, Jamunapari and Sirohi crossbred goats in Surkhet district of Karnali province, Nepal | N. Bhattarai, J. Poudel, M. R. Kolakshyapati, M.P. Sharma, N. A. Gorkhali, A. Sigdel, S. Upadhayaya, and S. Sapkota Material Type: printed text Authors: N. Bhattarai, Author ; J. Poudel, Author ; M. R. Kolakshyapati, Author Publication Date: 2022 Article on page: 71-80 p. Languages : English (eng) Keywords: Breed, parity, production system, season, weight Abstract: Goat produces 20.36% of meat, ranking in second position after buffalo meat production in Nepal and contributes
4% in agriculture GDP. Making out the influence of non-genetic factors on the phenotypic expression of
reproductive and litter traits of goat is important to develop selection/evaluation criteria with healthier precision.
Khari, Jamunapari and Sirohi crosses were considered for the comparative study of their reproductive and litter
traits. Data obtained from the study of different reproductive and litter traits were firstly entered into the computer
via excel package programs. The data were analyzed by Mixed Model Least-square and Maximum Likelihood
Computer Program PC-2statistical package developed by Walter R. Harvey and the means were compared by
Duncan’s Multiple Range Test (DMRT). Results revealed that the pooled means for AFC, AFK, PPE, GL, and KI
were 344.31, 493.69, 173.42, 148.93, 319.58 days respectively. Similarly, pooled means for LSB, LWB, LSW,
and LWW were 1.43, 5.16 kg, 1.37 and 28 kg respectively. Production system and breed were important nongenetic factor affecting reproductive traits significantly whereas parity is the most important non genetic factor
affecting litter traits of goat. Almost all of the reproductive traits (except PPE) were observed better under the
grazing system in Khari breed. Winter kidding goat had better PPE. Likewise, all the litter traits were significantly
better in later parities with almost similar performance in all the breeds. To summarize, Khari was explored as a
high potential goat regarding its reproductive traits with a massive scope of improvement in its litter weight trait
through effective selection measures within the populationLink for e-copy: https://afu.edu.np/sites/default/files/Evaluation_of_reproductive_performance_an [...]
