| Title : | LATVIAN BROWN LOCAL BREED AND OTHER BREED COWS MILK YIELD, COMPOSITION AND DRY MATTER INTAKE ANALYZE |
| Abstract : | Dry matter intake for dairy cows is very important factor for milk producing. The feeding cost decrease if dry matter intake per one kilogram of milk decrease too. This factor depends of dairy cows breed. The purpose of research was to analyze different breed milk yield and composition, dry matter intake per one kilogram of milk. Data was collected from 2012 to 2013 year. Data was collected from 9 Latvian Brown local breed (genetic resources), 10 Latvian brown breed with Holstein blood, 9 Danish Red and 10 Holstein Black and White breed. Research location was Latvia University of Agriculture Research and Study farm Vecauce. All cows, except genetic resources, were kept in loose housing farm and fed with total mixed ration. Genetic resources were kept in summer time pastures. Data was collected from milk recordings (first five recordings after calving). Milk yield of Latvian Brown local breed was significantly lower in all recordings compared with other research groups (average 17.8 kg per day). Milk yield of Holstein Black and White was significantly higher compared with local breed (average 30.9 kg per day; p<0.05). Fat content was significantly different between GR, LB and HBW, but protein content was significantly different in 3rd recording between Danish Red and local breed (3.27 vs. 2.91; p<0.05). Dry matter intake per one kilogram milk was significantly higher from local breed cows (average 0.89 kg), but lower Holstein Black and White (average 0.64 kg; p<0.05). |
