Genetic parameters and trends for lamb survival and birth weight in a Merino flock divergently selected for multiple rearing ability.
Data of 5,390 Merino lambs born from 1986 to 2007 (approximately 6.9 generations) were used to derive genetic parameters and trends for age-specific and overall lamb survival on the underlying scale, as well as for lamb birth weight, using Gibbs sampling. The majority of lambs were descended from lines that were divergently selected for the ability of ewes to rear multiples. The line selected i...

The objective of the present study was to estimate genetic parameters and trends for average daily gains and Kleiber ratios in Moghani sheep. The included traits were average daily gain from birth to 3 months of age (ADG1), average daily gain from birth to 6 months of age (ADG2), average daily gain from 3 months to 6 months of age (ADG3), average daily gain from 3 months to 9 months of age (ADG...
متن کاملGenetic and Phenotypic Trends of Productive and Reproductive Traits in Iranian Holstein Dairy Cattle of Isfahan Province
Productive and reproductive traits have great importance in international dairy cattle breeding objectives. Production, reproduction (days open and calving interval) and pedigree data of Iranian Holstein dairy cattles were collected between 2002 and 2012 from 47 herds in Isfahan province. The data set consisted of 30179 records from 18837 registered IranianHolstein dairy cattles. Single trait r...
