Performance analysis of the Florina (Pelagonia) sheep for lamb production and growth

Lambing and lamb weaning records collected during the period 1976-1977 to 1994-1995 were used to estimate the lamb production characteristics of the Florina breed of sheep. The records w6re also analyzed using Garvey's mixed model by least squares and maximum likelihood computer programme to es...

Summary:Lambing and lamb weaning records collected during the period 1976-1977 to 1994-1995 were used to estimate the lamb production characteristics of the Florina breed of sheep. The records w6re also analyzed using Garvey's mixed model by least squares and maximum likelihood computer programme to estimate the effect of year, month of birth, dam's age and lactation number, type of lambing, sex and interaction between type of lambing and sex on birth weight, weaning weight and daily gain to weaning. Overall fertility rate was 84.4, prolificacy rates were 1.15 and 1.36, based on the number of ewes mated and number of ewes lambing, respectively, and the lamb survival rates to the age of slaughter (soon after weaning) 94.5.
