Imported milch cow amount in Shaanxi in recent years is up to be more than 3000 heads, taking above 10% in provincial milch cow in-shed. According to investigation in imported milch cows carried out by concerning department of Shaanxi, many obvious problems exist in the imported milch cows: 1. Low milk producing quantity. Produce capability of milch cows imported from Australia is not high, milk yield in the first birth milk period is around 5000kg, generally the same as that in Australia, but lower than domestic advanced level. Milk industry of Australia is in mid-level of world. According to statistic data in FAO, milch cows in shed in Australia are about 2,200,000 heads, and average yield per head is about 5167kg, while breed-cow with yield more than 8000kg has a small amount. 2. Without complete record. As is learned, only 200heads milch cows imported from Australia have genealogy, most milch cows only have simple cards and variety testify from Australia Holstein Cattle Association, and the card only records the cow's ear number and its birthday. Australian cows are mainly raised in browsing way, and the management is extensive, while manual work is expensive, only a few good-kind cows have complete record. 3. Offspring birthed by pregnancy cow imported from abroad is not with pure breed. According to the testing on 172 cows from Australia in Yangling Group, seen from appearance color and luster of new born calves, black- white cows take 42%, pure black takes 20%, red-white and yellow as well as other colors take 38%. It is obvious that the ox used in hybridization includes Holstein, Jersey, even the meat cattle such as Angus, Hereford, Simmental, Denmark red cattle, Germany yellow cattle. Withal, milk industry expert says, milch cow imported from Australia must be strictly controlled, and cow quality must be exactly controlled. Present cow-in-shed in Shaanxi is up to 350,000heads, generally satisfying provincial demand in diary products processing. Guiding antilogy in future Shaanxi milk development is to stabilize in-shed milch cow amount, improve heredity quality, improve breeding management level, improve yield of per unit area, increase profit.
