Abstract
This study was carried out to evaluate compositions of milk from Hair goat and Saanen x Hair goat crossbreed (F1) under semi-intensive conditions. The research was conducted on 20 Hair goats and 20 Saanen x Hair goat crossbreed (F1) at Farm for Research and Application of Van Yuzuncu Yil University in Turkey. All the experimental goats were 3 years old and were raised under semi-intensive conditions. In the current study, the average fat, non-fat solid, protein, lactose, total solids, lactic acid, pH values of Hair and crossbreed goat milks were 3.98%, 3.80%; 9.54%, 9.24%; 3.59%, 3.48%; 5.24%, 5.08%; 13.51%, 13.04%; 0.24%, 0.25%; 6.62, 6.64, respectively. Lactation stage had a significant influence (P<0.05; P<0.001) on milk fat, non-fat solid, protein, lactose, total solids contents and lactic acid value in Hair and crossbreed goats' milk. Also, genotype had a significant influence (P<0.001) on non-fat solid, protein, lactose and total solids contents of the milk. In conclusion, Hair goats and crossbreed goats produce milk with a variable milk fat, non-fat solid, protein, lactose, total solids contents at the different stages of lactation. The mean values of milk non-fat solid, protein, lactose and total solids in Hair goats' milk were higher than those of crossbreed goats. Also, milk fat content, lactic acid and pH values in Hair and crossbreed goats' milk were similar.

Summary
Goat breeding is an important livestock activity for underdeveloped and developing countries due to the low cost of production. Goat milk consumption supplies well and balanced nutrition for the children. The nutritional value of milk is tightly interested in its composition, which is influenced by factors such as breed, feeding, lactation stage, season, etc. One of the major factors that affect milk yield and composition is the stage of lactation. Ciappesoni et al (2004) found that milk protein of Czech White Shorthaired Goats was significantly influenced by effect of stage of lactation. Studies on milk compositions of pure and crossbreed goats, in Turkey and similar agroecological zones, are limited. Further researches are needed to evaluate milk components of pure and crossbreed goats in these zones. This research was carried out to evaluate compositions of milk from Hair goat and Saanen x Hair goat crossbreed (F1) under semi-intensive conditions
