FACTORS AFFECTING ACTUAL AND ADJUSTED 90-DAY, 205-DAY AND 365-DAY WEIGHT OF CHAROLAIS CALVES

Body weights on 90 ± 45 days and 205 ± 45 days are body weights used for selection in suckler herds, likewise body weight on 365 ± 45 days are used for selection in performance test according to the Slovenian rules for recording in animal production, which is based on the International Committee for Animal Recording - ICAR. Dilemma which body weights are more suitable: the actual, or the adjusted ones at the recommended age of calves is often present. Comparison between fixed effects on actual and on adjusted 90-day, 205-day and 365-day weights of Charolais calves have been studied. Calves (320) were born from 1995 to 2005 on Educational and Research Animal Husbandry Centre Logatec (Slovenia). Fixed effects of sex, parity, year of birth and birth weight were included in a model for the actual and adjusted body weights. Birth weight was included as linear regression. It has been concluded that parameters affected the actual body weights affected adjusted body weights, too. Birth weight and year of birth influenced 90-day, 205-day and 365-day weight. Parity influenced only 90-day weight, while sex influenced 205-day and 365-day weight. Coefficients of determination for adjusted 90-day weight (0.38), 205-day weight (0.38) and 365-day weight (0.73) were higher than for actual body weights (0.20, 0.30 and 0.60, respectively)

Utjecaj tehnologije hranidbe na hematološke pokazatelje kod bikova cika i simentalske pasmine.

Cika cattle are an indigenous breed in Slovenia, while the Simmental breed is a cosmopolitan breed. The fattening trial was prepared to investigate whether Cika bulls are suitable for beef production, and the Simmental bulls were kept for comparison. The aim of this study was to investigate if different feeding technologies affect the haematological parameters of Cika and Simmental bulls. Blood samples of 17 Cika and 19 Simmental young bulls were taken in tubes with EDTA. The number of erythrocytes (RBC), leucocytes (WBC) and platelets (PLT), and the values of haemoglobin (Hb), haematocrit (PCV), the mean corpuscular haemoglobin (MCH), the mean corpuscular haemoglobin concentration (MCHC) and mean corpuscular volume (MCV) were measured with a haematological analyser ABC Vet. Differential white blood cells counts were also prepared. Data were analysed by the GLM procedure from the statistical package SAS/STAT regarding the breed, feeding technology and their interaction as fixed effects. In the blood of Cika bulls there was a significantly higher number of leucocytes as well as haemoglobin, haematocrit, MCV and MCH values than in the blood of Simmental bulls, while the number of platelets was higher in the blood of Simmental bulls. Different feeding technologies signifi cantly affected the erythrocyte count, and MCV and MCH values, where pasture reared bulls had lower erythrocyte and higher MCV and MCH values compared to stable fattened bulls. In the differential white blood cell count of Cika bulls there was a significantly higher percentage of segmented neutrophils and a lower percentage of lymphocytes compared to Simmental bulls.Cika je autohtona pasmina goveda u Sloveniji, dok je simentalska rasprostranjena diljem svijeta. Tijekom istraživanja, organiziran je pokusni tov kako bi se utvrdila prikladnost bikova pasmine cika za proizvodnju junećeg mesa. Bikovi simentalske pasmine poslužili su za usporedbu. Cilj je bio istražiti je li različite tehnologije hranidbe utječu na hematološke pokazatelje kod bikova cika i simentalske pasmine. Uzorci krvi od 17 cika i 19 simentalskih bikova prikupljeni su u epruvete uz dodatak EDTA. Uz pomoć ABC Vet. analizatora utvrđen je broj eritrocita, leukocita, trombocita, te vrijednosti hemoglobina, hematokrita (engl. PCV), prosječni sadržaj hemoglobina u eritrocitima (engl. MCH), prosječna koncentracija hemoglobina po eritrocitu (engl. MCHC) i prosječni obujam eritrocita (engl. MCV). Također su utvrđene i razlike u tipu i broju leukocita. Podatci su analizirani pomoću GLM postupka statističkog programa SAS/STAT uz uvažavanje pasmine, tehnologije hranidbe i njihove interakcije kao fiksnih učinaka. U krvi bikova pasmine cika ustanovljen je signifikantno veći broj leukocita te veće vrijednosti za hemoglobin, hematokrit, MCV i MCH u odnosu na krv bikova simentalske pasmine. Istovremeno, broj trombocita bio je veći u krvi bikova simentalske pasmine. Različite tehnologije hranidbe signifikantno su utjecale na broj eritrocita, te vrijednosti MCV i MCH, pri čemu su pašno uzgojeni bikovi u odnosu na bikove uzgojene u staji imali manji broj eritrocita i veće vrijednosti MCV odnosno MCH. Razlike u tipu i broju leukocita pokazale su da bikovi pasmine cika, u usporebi s bikovima simentalske pasmine, imaju signifikantno veći postotak segmentiranih neutrofila i manji postotak limfocita

Carcass Quality of Slaughtered Cika and Brown Cattle in Slovenia

The aim of the study was to compare carcass traits between Cika and Brown cattle of all slaughter categories. The data used were collected in Slovenian slaughterhouses from 2007 to 2010. After the slaughter carcass weight was recorded and carcass conformation and fatness were scored according to the EUROP system. Net daily gain was calculated. Data were analysed by GLM procedure of statistical package SAS/ STAT considering breed, month of the slaughter and year of the slaughter nested within the breed as fixed effects. Cika bulls (under 24 months old) were two months younger at slaughter (20.2 months) and achieved lower carcass weight (266.7 kg) compared to Brown bulls (22.4 months, 330.0 kg). Also in all other categories except in calves under eight months old, Brown cattle had higher carcass weight. Bulls under 24 months old, steers, cows and calves over eight to 12 months old of Brown cattle were older at slaughter compared to Cika breed. Net daily gain was also higher in all slaughtered categories of Brown cattle. Even if the slaughtered Brown cattle had heavier carcass weight compared to Cika cattle there was almost no significant difference in carcass conformation. Carcasses of Cika bulls under 24 months old had conformation 6.4 while Brown bulls 6.3. Likewise carcasses of Cika calves over eight to 12 months had higher conformation score (5.7) than Brown (4.8) calves. Fatness was higher in Brown bulls, steers and heifers compared to Cika cattle, while Cika cows had higher fatness than Brown cows

The Effect of Pinzgauer Introgression on the Red Pied Sided Coat Colour of Cika Cattle

The aim of this study was to evaluate the effect of the proportion of Pinzgauer cattle in the pedigree of the Cika cattle on the coat colour pattern. Both breeds share similar pied sided coat colour pattern. A total of 66 male and 237 female animals, aged from 4 days to 13.1 years were included in the study. Th e width of the white stripes on the back, on the rump, on the front and on the rear legs were measured with the tape. Th e red basic coat colour intensity was performed by Minolta CR-300 Chroma meter using CIE (L*a*b) colour system at three parts of the body (shoulder, rare ribs, round). All animals were measured in the spring after housing period. The GLM procedure (SAS/STAT) considered fixed effect of sex and the proportion of Pinzgauer cattle in the pedigree of each Cika animal as linear regression. The effect of sex significantly affected the width of white stripes on the back, rump and rear legs as well as the red colour intensity (a*). Females had significantly wider white stripes and more intensively red coat colour than males. The effect of the Pinzgauer proportion in the pedigree of Cika was found significantly related to white stripes on the back and rump as well as in all three coat colour parameters (L*a*b). White stripes on the back and rump significantly increased, while values of L* (lightness), a* (redness) and b* (yellowness) significantly decreased with increased Pinzgauer proportion in the pedigree. Introgressed Cika animals with Pinzgauer had wider white stripes on the back and rump as well as darker coat colour with less intensively red and yellow shades. Th e results comply with an eye evidence of differences in the coat colour pattern according to sex and pedigree data. However, genetic characterisation found introgression of other breeds besides Pinzgauer in some Cika animals, which could influence the coat colour as well
