Production traits and haematological parameters of goat kids in organic system

Cilj ovoga rada bio je utvrditi proizvodne i hematološke pokazatelje jaradi na ekološkom obiteljskom poljoprivrednom gospodarstvu. Istraživanje je provedeno na obiteljskom gospodarstvu „Franjo Lehki“. Uzimanje tjelesnih mjera jaradi provedeno je uz pomoć Lydtinova štapa i mjerne vrpce, a određivanje tjelesne mase izvršeno je pomoću stočne vage. Tjelesna masa i tjelesne mjere uzete su od 20 jaradi pasmine francuska alpina u dobi od 30, 50 i 80 dana. Prije uzimanja tjelesnih mjera, istoj jaradi je izvađena krv. U punoj krvi određeni su broj eritrocita (RBC) i leukocita (WBC), sadržaj hemoglobina (HGB) i hematokrita (HCT), prosječan sadržaj hemoglobina u eritrocitima (MCH), prosječni volumen eritrocita (MCV) te prosječna koncentracija hemoglobina u eritrocitima (MCHC). Dobiveni rezultati statistički su obrađeni primjenom paketa SAS 9.4®. Jarad je u istraživanju ostvarila dnevni prirast od 172,36 g u dobi od 30 do 50 dana, odnosno 111,79 g u dobi od 50 do 80 dana, dok je ukupni prosječni dnevni prirasti jaradi od 30. do 80. dana iznosio 136,02 g. Tjelesna masa i većina tjelesnih mjera značajno su se povećali s povećanjem dobi jaradi. Utvrđeni hematološki pokazatelji većinom su bili unutar referentnih vrijednosti za jarad. Navedeno ukazuje na zadovoljavajuć rast i razvoj jaradi u ekološkom sustavu uzgoja.The aim of the present paper was to determine production traits and haematological parameters of goat kids in organic family farm. Research was carried out at "Franjo Lehki" family farm. Determination of body measurements from goat kids were done using a Lydtin's stick and measuring tape, while body weight was determined using a cattle scale. Body weight and body measurements were performed on 20 goat kids of French Alpine breed at the age of 30, 50 and 80 days. Before determination of body measurements, blood samples were collected. In whole blood number of erythrocytes (RBC) and leukocytes (WBC) were determined, as well as content of haemoglobin (HGB), hematocrit (HCT), average amount of haemoglobin in erythrocytes (MCH), average volume of erythrocyte (MCV), and concentration of hemoglobin in erythrocytes (MCHC). The results were analysed using SAS 9.4®. Average daily weight gain of goat kids was 172.36 g in the age from 30 to 50 days, and 111.79 g in the age from 50 to 80 days, while total average daily gain from 30 to 80 days of age was 136.02 g. Body weight and the most of the body measurements increased significantly with age of goat kids. Determined haematological parameters were mostly within reference values for goat kids. Abovementioned indicated adequate growth and development of goat kids in organic production system
