A STUDY OF ENVIRONMENTAL EFFECTS ON GROWTH TRAITS OF ZANDI SHEEP

Pages

  33-37

Abstract

 A study was carry out to evaluate of the effects of environmental factors on growth traits in a Zandi flock (Khojeir Research Station- Animal Husbandry Department of Tehran province.Jahad-e- Sazandegi orgaization). Data of 1628 lambs during 1992 to 1998 on birth. Weaning, 6-month. 18-month weights, Average daily gain from birth to weaning and weaning to 6- month were analysed by GLM method to calculate Least Squar Means (LSM). SAS program was employed for ANOVA analysis. According to the results effects of sex, birth type age of dam, and birth year were significant for all traits (p<0.01), Interaction effects between sex by birth type were significant for all traits (p<0.05), except for 18-month weight. The effect of sex by age of dam were significant for all traits (p<0.05), except birth and 18- month weights, and birth type by age of dam were significant only for average daily gain traits (p<0.05). Overall Least Squar Means for the traits that mentioned above were 3.97±0.03; 19.28±0.03; 29.33±0.38.32; 44±0.57; 43.59±0.69; 0.172±0.004; 0.130±0.003 Kg Respectively.
