    The evaluation of a type’s conformation is a preliminary indicator of lactation, longevity and reproductive performance. Linear assessment belongs to the group of selection measures and consists the basis for evaluation and selection of genetically high-quality breeding heads. The cows should preferably be evaluated during the first lactation, 30 to 150 days after calving. The main objective of our research was a visual assessment of HolsteinFriesian dairy cows, 352 heads in total, on two major farms in the Republic of Macedonia, using a linear evaluation method. The cows in Farm 1 were kept in a loose system of rearing, while the cows in Farm 2 were kept in a tied system of rearing. The following linear features were evaluated: format, chest width, body depth, dairy character, rump position, rump width, rear legs – back view, rear legs – side view, foot angle, fore udder attachment, front teats’ positioning, teats’ length, udder depth, rear udder height, suspensory ligament, rear teats’ positioning and overall condition evaluation, which were then reduced to 4 aggregate features. The analysis of the data obtained, yielded the following average values of those aggregate linear features for Farm 1: format 5.79, dairy character 5.84, legs and dewclaws 5.83, udder 5.76; and for Farm 2: format 5.14, dairy character 5.42, legs and dewclaws 5.38, udder 5.36. Thereby we can draw the conclusion that the values of the aggregate linear features are within the average, being insignificantly higher in Farm 1 with the loose system of rearing. The average milk quantity in the period of 305 days was 7,374 kg per cow in Farm 1 and 6,895 kg in Farm 2

    The role of goats in world livestock is significant and there is not a country in which they are not bred. The goat production in the Republic of North Macedonia is characterized by spontaneous and continuous development, and with each day there is greater interest of farmers for breeding goats as a business that provides secure existence and profit. The aim of the research within this study was to assess productive characteristics of conventional goat farm operating in the Zletovo region. The researches lasted 3 years (2008, 2009 and 2010) at the farm where around 100–120 heads of goats of all categories of the Alpine race are bred. Almost the whole milk produced at the farm is processed into dairy products such as: white brined cheese and cashkawall. The kids born there are used as kids for market of livestock products, kids sold as breeding goats and part of them are retained for own reproduction in the herd. The percentage of fertility was the highest in 2010 (125.32%), in 2009 was 122.99% and in 2008 was 118.99%. The percentage of conception was the higest in 2009 (90.63%), in 2008 was 87.78% and in 2010 was 82.29%.The average lactation length in 2008 was 258.3 days, in 2009 was 265.4 days, and in 2010 was 261.7 days. The average daily amount of milk production in 2008 was 0.93 liters, in 2009 was 0.96 liters, and in 2010 was 1.01 liters per head. The average milk yield in 2008 was 241.23 liters, in 2009 was 251.47 liters, and in 2010 was 263.57 liters. The farm worked with profit in all three years of research.
