  The authors carried out an examination on two Saanen goat farms during four months from May to August 2008. The body condition score and milk production of the goats were measured. In data processing analysis of variance was used to compare the data of the studied farms. They tried to find the answer for the question how the body condition scores and milk production change in each month. The changes observed in each farm were examined separately then they compared the values of the two farms.. On one of the farms the nutrition was proper therefore with an ideal, intermediate body condition (average 2.73) the goats produced a good amount of milk (2.5 milk-kg/mother/day). On the other farm the nutrition was not proper, therefore the body condition of the goats was weak (average 1.88). Their milk production decreased significantly from month to month (average 2.35 milk-kg/mother/day). The authors could conclude considering both farms that the more milk the goats produced, the lower their body condition score became. The two parameters showed negative correlation.

  We carried out the examinations on a farm of 500 cows where We examined the body condition of the stock every month. We recorded the body condition data together with the milk production and calving data. We analysed the daily milk production as well as the body condition. During the examinations we sought an answer how the body condition and the production level change during the lactation period.

  The authors examined the body condition with relation to reproduction of Holstein-Friesian cows on three dairy farms in the South Plain region. During the examination they analyzed the data of 516 births of 494 Holstein-Friesian cows. They were trying to find correlation between the first service, the service period and the service rates. The examinations with regard to the correlations were different from the ones published in the professional literature. The body condition at the time of calving affected the interval from calving to the first service but not the conception
  rates or the service period. The examinations did not prove any correlations between body condition changes and reproduction.

  The authors examined the data of 2767 trial milkings andthe months Body Condition Scores of 479 Holstein dairy cows. The condition loss was significant between the 30-60th days. The improvement of BCS begins only after the 120th day. The change in the milk protein and milk fat content were close after the condition changing. In each period of the lactation the closeness of the relationship among the condition, the milk quantity and the milk composition were different. In the aspect of the milk quantity the most significant difference was between the 2.5 and 4 BCS cows (6.68 kg) in the last period of the lactation.

  In the last 20-30 years, lameness in cattle was found to be third the most influential disease next to mastitis and reproduction disorders. Studies have been established to explore reasons for lameness and prevention. The problem with more robust prevention plans is that knowledge and research evidence is not strong enough to run an effective prevention plan. The aim of the research is to look for reasons of lameness by observing number of cows on 6 farms during 2 lactations. Performance data will be put together to body condition score (BCS) and lameness scores. Other examination is focused on monitoring of 40 farms. This part of the project is more related to extension, collecting and sharing solutions for decreasing lameness. Producers are advised what kind of measures are possible to reduce occurrence of lameness. Effectiveness of those actions will be measured at the end of the study. The first preliminary results show lack in almost all preventive measures needed to be taken in minimizing lameness. Those areas are related to poor facilities, lack of straw, problems with labor and basic management.
