Abstract: Community-based breeding programs (CBBPs) for small ruminants have been suggested as alternatives to centralised,government-controlled breeding schemes which have been implemented in many developing countries. An innovativemethodological framework on how to design, implement and sustain CBBPs was tested in three sites in Ethiopia: Bonga, Horroand Menz. In these CBBPs, the main selection trait identified through participatory approaches was 6-month weight in all threesites. In Horro and Bonga, where resources such as feed and water permitted larger litter sizes, twinning rate was included.Ten-year (2009 to 2018) performance data from the breeding programs were analysed using Average Information RestrictedMaximum Likelihood method (AI-REML). Additionally, the socioeconomic impact of CBBPs was assessed. Results indicated that6-month weight increased over the years in all breeds. In Bonga, the average increase was 0.21±0.018 kg/year, followed by0.18±0.007 and 0.11±0.003 kg/year in Horro and Menz, respectively. This was quite substantial in an on-farm situation. Thebirth weight of lambs did not improve over the years in Bonga and Horro sheep but significant increases occurred in Menz.Considering that there was no direct selection on birth weight in the community flock, the increased weights observed in Menzcould be due to correlated responses, but this was not the case in Bonga and Horro. The genetic trend for prolificacy over theyears in both Bonga and Horro flocks was positive and significant (P<0.01). This increase in litter size, combined with theincreased 6-month body weight, increased income by 20% and farm-level meat consumption from slaughter of one sheep peryear to three. The results show that CBBPs are technically feasible, result in measurable genetic gains in performance traits andimpact the livelihoods of farmers.

Environmental and production factors might affect grapevine physiology. Estimating these effects is essential for planning the harvest and predicting the quality of grapes. The aim of this study was to characterize the quality and antioxidant potential of ?BRS Cora? grapes with different training systems and rootstocks in production cycles of the second half of the year under tropical conditions. The experimental design was randomized blocks with sub-subdivided plots over time. Three training systems and two rootstocks were studied in production cycles referring to the second halves of 2017 and 2018. In 2017, the grapes of plants trained with lyre and vertical shoot positioning (VSP) had the highest soluble solids and sugars contents, and in 2018, this response occurred with the overhead trellis system. There was lower variation in titratable acidity between cycles of grapevines trained with VSP and lyre, as well as in those grafted onto ?IAC 572?. In 2018, lyre with ?IAC 572? promoted higher pigment accumulation. Climatic conditions in 2017 provided a higher accumulation of polyphenols and antioxidant activity in grapes of plants trained with lyre with ?IAC 766?. The efficiency of the training system within each cycle, associated with the effect of the rootstock, resulted in differentiated responses according to climatic conditions. |
