【摘要】 本文通过对某牛场１０ 头西门塔尔牛产奶量与其体型线性性状进行相关、回归分析。试图找出与产奶量相关性大，且具有最优回归关系的体型线性性状。结果表明：尻长、乳房深、体高、胸围、乳头长与其产奶量呈弱正相关；尻宽与产奶量接近于中等正相关；但尻长、乳房深、体高、尻宽、胸围、乳头长六个线性性状与其产奶量均没有最优回归关系更多还原

【Abstract】 In this paper analysis of correlation and regression on 20 Ximen TaR cows’ milk product and their figure linear characters were done to try to find out figure characters which were pronouncedly correlative to milk product and had the best regression relations to milk product. The results showed that buttocks length, udder depth, boddy height , thorax measurement and teat length were feebly positively correlative with milk product. The buttock width was close to medium correlation. However there were not the best regression relations between buttocks length, udder depth, body height, buttocks width, thorx measurement and teat length and milk product.更多还原
