Simulation of Alternative Plans for Community Based Goat Breeding Program in Arid, Semi-Arid and Mixed Production Systems in Ethiopia por Jembere, T., Rischkowsky, Barbara A., Dessie, Tadelle, Kebede, K., Okeyo Mwai, Ally, Mirkena, T., Haile, Aynalem

“…Three scenarios including selection on dam side (SN2) in addition to SN1, application of genomic selection (SN3) onto SN1 and use of sires from SN1 for mating in additional flocks (SN4) were simulated and compared with SN1 based on the predicted annual genetic gain (PAGG) and discounted profits. The breeding objective traits or selection criteria were six month weight (6mw, kg) for all breeds, average daily milk yield (ADM, kg) and survival to six month of age (SURV) for AB, litter size at birth (LSB) for CH and WG, litter size at weaning (LSW) for CH and kidding interval (KI, days) for WG. …”

Sensory Characteristics, Nutritional Composition, and Quality of Eggs from Different Chickens por Hailemariam, A., Esatu, Wondmeneh, Abegaz, Solomon, Urge, Mengistu, Assefa, Getnet, Dessie, Tadelle

“…Conclusively: the eggs of L, H, and C genotypes were best favored followed by CH and C, but the KK genotype was the least favored, and these differences were deemed due to genetic variations, and interventions. Furthermore, the eggs laid from genotypes with deep yellow yolk color might be the most nutritious. …”
