This study was carried out to determine the effect of non-genetic factors on growth and reproductivetraits in Saanen goats. For this aim, total of 274 Saanen goats and kids were investigated for growthand reproductive traits in South Marmara Region of Turkey. Fertility parameters were evaluatedduring two reproductive years. Saanen kids were measured from birth to 6 months of life. Theaverage live weights at birth, weaning, 60th, 90th, 120th and 180th days of age were calculated anddetermined as 3.05±0.04kg, 11.80±0.27kg, 12.26±0.08kg, 14.20±0.32kg, 17.41±0.45kg,25.01±0.65kg, respectively. The effects of sex and birth type on live weights until 90th days of age;maternal age only on birth weight; month at birth on all of investigated days were found significantstatistically. The pregnancy, birth rate per pregnancy (BRP), birth rate per mating (BRM), infertility,abortion, kidding rate (single, twin or triplet), survival rate (until weaning), number of kids perparturition (NKP), number of kids per mating (NKM) were found; 92.98%, 85.07%, 91.25%, 7.02%,8.75%, 36.12%, 49.00%, 14.88%, 89.13% and 1.74±0.06, 1.42±0.07 respectively. The effects ofmaternal age on all rates (out of BRM and abortion rate); the year on birth, abortion, single kiddingrate, survival rate and NKM were found significant for reproductive traits. The advancedreproductive performance and rapid growth rates were observed in Saanen goats. Environmentalfactors such as age, year, sex, birth type and month at birth were found significant on some growthand reproductive traits in Saanen. So consideration of these factors could be useful as a selectioncriteria in dairy goat breeding.
