Early growth and survival rates of crossbred lambs (Dorper x indigenous) under semi-intensive management at Areka, Southern Ethiopia: Effects of non-genetic factors

Relationship of Body Weights with the Productive Performance of Lambs of the Awassi and Karakul Breeds and Crossbred Sheep

“…The findings presented in Table (3) indicate that the sex of lambs does not have a significant impact on their AWG during the period between birth and weaning, nor does it have any significant effect on their growth by the age of six months. These results agreed with a number of studies [44,45]. Saltani & Azzawi [62] explained that the reason for this is due to the nutritional environment of mothers before and during pregnancy and for newborns after birth, which causes no differences between the sexes to appear, while the results of the current study didn't agree with the claims made by some researchers [47] that a newborn's sex has a substantial impact on their rate of AWG during the birth, weaning, and the age of 6 months of their life.…”

Growth and growth curve analysis in Dorper × Tumele crossbred sheep under a smallholder management system

“…The BWT of Dorper × indigenous sheep found in the current study is higher than the reports of several scholars ( Belete et al, 2015 ; Abebe et al, 2016 ; Gemiyo et al, 2017 ) for Dorper crossbred sheep. Likewise, the WWT of Dorper × Tumele sheep in this study is higher than the reports of several studies ( Mekuriaw et al, 2013 ; Tilahun et al, 2016 ; Gemiyo et al, 2017 ; Amare et al, 2018 ) for indigenous and crossbred sheep.…”

The preweaning gain of Dorper × Tumele sheep observed in this study is lower than the value reported for pure Dorper (142.93 g day −1 ), but higher than the value reported for 50% Dorper × Menz sheep (106.24 g day −1 ) under semi-intensive management ( Abebe et al, 2016 ) and also higher than the result (99.8 ± 2.4 g day −1 ) reported for Dorper × Adilo sheep by Gemiyo et al (2017) .…”

This indicates that the pre-weaning growth performance of Dorper × Tumele sheep was better than other crossbred and non-improved indigenous sheep breeds.…”

Evaluating Flock Dynamics, Offtake-rate, and Farmers’ Perception on Benefits of Community Based Breeding Program in Doyogena District, Central Ethiopia

“…This higher off-take rate in the breed improvement cooperative can be attributed to the strategic culling of unproductive animals, the implementation of fattening practices tailored for festivals, disseminating improved rams, and collaboration within the group leading to improved market opportunities. In contrast, non-participants tended to sale animals at younger ages, aligning with findings from Deribe et al (2021) and Kocho et al (2011), who noted that in Alaba district, sheep and goat keepers sold their animals before reaching breeding age. The off-take rate (53.8%) in this study is higher than other research endeavors.…”
