Conservation-based breeding program design for genetic improvement in Gumz sheep in the western lowlands of Ethiopia

Table 3 Genetic gain per year in the breeding objective and its component traits achieved from selection using four alternative Gumz sheep breeding schemes

	Village-based schemes		Central nucleus-based scheme
	Scheme-1	Scheme-2	Scheme-3	Scheme-4
Breeding objective^a	5.71	6.31	12.29	12.37
SWT (kg)	0.154	0.171	0.334	0.336
LTS	0.0017	0.0018	0.0036	0.0036
PWS	0.0015	0.0016	0.0029	0.0029

^aThe annual monetary genetic gains for the breeding objective were calculated as a sum of the products of the respective genetic gains and economic weights of the component traits (SWT: six-month weight, MWT mature weight, LTS litter size and PWS pre-weaning survival)
