System dynamics modelling approach has been widely used in the agriculture sector to describe livestock production systems, livestock health and natural resource management. However, its application in modelling livestock breeding programs and systems is limited. Therefore, this study explores th...

About 60 Black Head Somali rams were used in 21-month experiment period (18 months for growth to maturity and 3 months for fattening) to investigate the effect of age at castration on growth to maturity, fattening capability after maturity and market value of fattened mature rams which had been c...

Mortality was studied in relation to birth weight (BWT) and postpartum age in 3083 Horro lambs born over 15 years at Bako Research Center, IAR. Pre-weaning mortality rose with declining BWT (log y = 2.20- 0.35X; r = 0.9981), but the influence after weaning was less pronounced and linear (y = 23.7...
