Relationships between production traits and the parity of Polish Holstein-Friesian cows. The objectives of the study was to describe the relationships between milk urea, protein, fat concentrations and the age of Polish Holstein-Friesian cows. The experiment was carried out at the research dairy farm of the Warsaw University of Life Sciences (WULS). From a herd of 320 Polish Holstein Friesian cows maintained in a free–stall dairy shed 50 cows were selected. Parity had significant effect on the shaping the concentration of the production traits. The highest content of protein, 3.87%, was found in milk of cows during 3rd and subsequent lactations in the 10. collecting (above 271 day of lactation). The fat content ranged at the herd level from 3.18 to 4.89 %, the highest level has been recorded in milk of cows during 3th and subsequent lactations, in the 10. collecting (above 271 day of lactation). The urea content ranged at the herd level from 183 to 267 mg L -1. Milk production traits varies significantly with the age of cows. Hence, researchers should consider monitoring for this variable as potential cofounder when exploring the relationship between urea, protein, fat content in milk and nutritional management for meeting the production requirements of cows.

The length of gestation in Carthusian broodmares was calculated on the basis of 339 spontaneous full-term deliveries taking place in the 8-year period 1998-2005 from 158 broodmares and 29 stallions in a major farm of Spanish horses of Carthusian strain in southern Spain. Ultrasonography was used to determine follicular dehiscence, 1st day of pregnancy and to confirm conception in mares. Mean GL was 332.4 ± 12.1 days, and a normal interval of 297-358 days was established for this breed. GL records were grouped on the basis of foal sex (colts or fillies), mating month (between November and January; February and April; May and July), age of the mare (4 to 7 years; 8 to 12 years; 13 to 17 years), breeding year, stallion and parity (primiparous vs. multiparous). GLs were 12.9 days shorter in mares mated between May and July than those mated between November and January and 15.3 days in mares mated between February and April (p<0.001). Mares aged between 8-12 years had 5.3 days shorter GLs than those aged between 13-17 years (p<0.05). Pregnancy was significantly 5.7 days longer when the mare gave birth to colts than fillies (p<0.05). GL was 14.5 days longer in primiparous than in multiparous mares (p<0.001). No statistical differences in GL were found between the studied years. This study shows the influence of certain stallion on GL.

The aim of this paper was to investigate the impact of clinical lameness in Polish Holstein-Friesian dairy cows on milk yield as well as on fat, protein, and lactose yields during early lactation (120 d). The dataset includes 312 monthly test-day milk yields and milk composition records from 78 cows, which calved from October 2008 to April 2009. Twice a week, during the first 120 d postpartum, the cows were examined for lameness and they were scored fortnightly according to a 5-point locomotion scoring system. Factors affecting milk yield and milk components included calving season, parity, month of lactation, and degree of lameness. In cows, which were clinically lame for a month and which were clinically lame for more than a month (maximum per 2 months), the total mean reduction in milk yield per 120-d lactation was approximately 308 and 283 kg, respectively, as compared with cows, which were never lame in early lactation.
