摘要: A study was carried out at the Okpara breeding farm in Benin. Records on 558 lambs of Djallonke sheep breed, born from 1997 to 2000, were used determine weekly growth curve birth up 119 days age. Non-genetic factors affecting lamb weights and 30, 60, 90 120 average daily gains 0 30 days, 60 investigated. linear model comprising fixed effects season, year, parity number ewe sex for analysis variance by least squares. All significant weight with exception weight, gain days. tended cancel Lambs dry season heaviest. Single male heavier than twins females. ewes 3rd 4th heavier, higher, gains.
