Item type:Publication, CORRELATION BETWEEN CERTAIN EXTERIOR AND PRODUCTION TRAITS IN INDIGENOUS BALKAN GOAT IN MACEDONIA(Macedonian Journal of Animal Science, 2017); ; The purpose of this research was to determine the average values of certain exterior measures and production traits in goats of the indigenous Balkan breed in the Republic of Macedonia as well as to study their mutual correlation dependence. It was determined that the average body weight of the goats of Balkan breed is about 44 kg, whereas the values of the other exterior measures were: height of withers 65.40 cm, height of back 63.67 cm, height of sacrum 65 cm, body length 65 cm, chest width 21.73 cm, chest depth 25.23 cm, size of chest 82.40 cm, rump width 19.92 cm, rump length 23.05 cm. The average lactation was 166 litres. Regarding the strength of the correlation, the general conclusion is that there is a relatively weak correlation (0.2 ≤ R < 0.5) between most of the exterior measures. An average strong correlation (0.5 ≤ R < 0.8) was determined between the height of the sacrum and the height of withers and the height of the back, between the length of the body and body weight, as well as between the chest size and the width and length of rump. A strong correlation (0.8 ≤ R < 1) was determined between the height of withers and height of the back, as well as between the chest size and body weight. With the analysis of the correlative dependence of the lactation with the other exterior measures, it was determined that the lactation is not in correlation with most of the exterior measures, but there is an insignificant correlation (0 < R < 0.2) with part of them (height of sacrum, chest size and length of rump). - Some of the metrics are blocked by yourconsent settings
Item type:Publication, PREDICTION OF TEST DAY MILK YIELD BY AC METHOD IN INDIGENOUS BALKAN GOATS IN MACEDONIA(Institute for Animal Husbandry, Belgrade-Zemun, 2017); ; Eftimova ElenaAccurate and precise milk recording is one of the most important moments for a successful selection of milking goats. In this context, breeders are constantly making efforts to find the most suitable and cheapest methods for conducting of tests for milk production. The goal of this research was to compare the A4 method (as referent method) with AC method (as alternative method), for determination of milk production, on the day of recording of the indigenous Balkan goat, in the period of 2014-2016 with milking of goats in the morning and evening. It was determined that the difference between the predicted daily milk yield with one milking (in the morning or evening) and the measured milk yield using the A4 method is too low and almost negligible. With the analysis of all factors (year, lactation and number of milk tests), it was determined that the prediction of total daily milk yield, based on the evening milking, provides more accurate result, in relation to the prediction during morning milking, in cases when using the AC method. - Some of the metrics are blocked by yourconsent settings
Item type:Publication, ACCURACY OF AC AND AT METHODS IN MILK RECORDING IN THE BALKAN GOATS BREED IN MACEDONIA(Bulgarian Journal of Agricultural Science, 24 (Suppl. 2) 2018, Agricultural Academy, 2018); ; CILEV GOCEThe aim of this research was to compare the AC and AT methods (as alternative methods) with A4 method (as referent method), for determination of milk production, on the day of recording of the indigenous Balkan goat, in the period of 2014-2016 with milking of goats in the morning and evening. Simultaneously, the influence of the following factors has been tested: year (year of kidding), lactation, month of kidding, milk yield level. It was determined that the largest deviation in the prediction of milk yield according to the AT method during morning milking was determined in 2016 with milk yield underestimated for -5.3 L, whereas the smallest deviation was registered in 2015 with milk yield underestimated for -1.8 L. The largest deviation in the prediction of milk yield according to the AC method during morning milking was determined in goats in first lactation, with milk yield overestimated for +3.8 L, whereas the smallest deviation was determined in goats in fourth lactation with milk yield underestimated for -0.3 L. With the analysis of all abovementioned factors, it was determined that the AT method is more suitable as al ternative and cheaper method for determination of accurate amount of milk
