The cholesterol content differed (P<0.05) between breast (49.5 mg/100 g) and back (74.3 mg/100 g) fat. Differences (P<0.05) in individual fatty acids were found especially for arachidonic acid (20:4).High contents of 18:2, 18:3 and 20:4 from both depots suggest, that ostrich fat could be a source of essential fatty acids in human and animal diets. The influence of various factors and especially feeding regimen on quantity and quality of ostrich fat should further be investigated.

Danube White (DW) sows are characterized by high fertility (total no. of piglets born) reaching 10.3 and 11.5. piglets in the first and fourth litter, as well as by high no. of piglets born alive – 10.0 and 10.6, respectively. Mean daily live weight gain of DW pigs fattened over a period of 91 days amounts to 780 g, and feed conversion ratio to 3,365 kg/kg gain. The mean backfat thickness from three measurements reaches 25 mm with high coefficient of variation suggesting a need and feasibility of further intensive selection to decrease the trait value. Although DW pigs are recognized as stressresistant (sensitivity to stress appears in 12.2% individuals), periodical control of the spread of Hal+ individuals within the population is suggested, assisted with a proper selection. DW pigs are considered suitable for traditional conditions of maintenance and feeding and thus for production of “ecological” meat.

Classification of slaughter animals in EUROP system is obligatory for all EU countries. Visual assessment of beef carcasses determines the level of muscle and fat in scales from E to P and from 1 to 5. At the same time beef carcass is classified into one of five categories of cattle for slaughter from A to E. Visual assessment is not fully objective and is fraught with classifier error, which has an impact on the final assessment of the carcass. 2689 beef carcasses were classified in different categories for slaughter. Assessments were performed by three classifiers independently and in the same conditions in the slaughter line. Based on the results of evaluations of beef carcasses were performed statistical analysis. The average value for the conformation was class O, which accounted for 52.66% of all beef carcasses and at a comparable level fat class 2 and 3 – 39.54%, 32.54% respectively, which is characterized by a low content of meat and average fat content in carcase. CV (coefficient of variation) for the SE (standard deviation) in the conformation class was around 3% for the three categories slaughter A, B and E, and D was 2.16%. For the fat class regardless of the category slaughter CV for the SE was 3 times larger. The results suggest that visual assessment of beef carcasses is not objective and is fraught with error evaluator.

The purpose of this study was to compare the haematological profile and meat colour of calves slaughtered in summer and autumn. The material covered 42 calves chosen randomly i.e. 22 slaughtered in summer (June-August) and 20 in autumn (October-December). Haematological analyses included haematocrit (HCT), haemoglobin level (HGB), red blood cells (RBC), white blood cells (WBC) and platelets (PLT). The morphology of the erythrocytes and platelets, and differentiation of leucocytes were examined. The colour of meat was evaluated instrumentally by Minolta CIE L*a*b* and haematin pigment content was determined. The blood haemoglobin content in calves in the compared seasons was similar (11.3 g/L) and found within a normal range. Blood of calves from the autumn season showed higher HCT, RBC, and MCV values with concurrent lower MCH and MCHC values in comparison to the summer season. Blood of calves slaughtered in summer showed a higher content of WBC and a significantly higher percentage of lymphocytes as against blood of calves from the autumn. Meat of calves from the summer season was paler (higher L* value), and had a significantly (p ≤ 0.05) higher proportion of yellowness (b*). A brighter colour of meat from calves presented for slaughter in the summer season was noted along with a lower content of haematin pigments. Significant correlations were found between haematological variables (HGB, HCT and RBC, particularly) and haematin pigment content and meat lightness (L*) and redness (a*).

The aim of the study was to determine the effect of slaughter age of broiler chickens on macromineral levels of breast and leg muscles and their association with meat quality. Used were fast-growing Hybro chickens kept on litter and fed the uniform diet. Ten chickens weighing 2 kg each were selected for slaughter at 35, 38 and 42 day of life. Breast and leg muscles were evaluated for pH,colour (CIELAB), water-holding capacity, drip loss, cooking loss, shear force, as well as for Na,Ca, K, P and Mg content. The birds’ age had an effect on the Na and K content of breast muscles and on the K, P and Mg content of leg muscles. No significant differences were found in most physicochemical characteristics of breast meat except pH which was the lowest in the oldest birds and cooking loss which was the highest in the youngest birds. No relationship between the level of individual minerals and meat quality traits was identified in breast muscles. In leg muscles Mg level correlated positively with pH15min and drip loss, P level with pH15min, and potassium level with waterholding capacity. Breast muscles turned out to be a richer source of K, Mg and P and leg muscles contained more Na.

Levels of Cortisol in blood serum of 50- and 100-day-old rams of Kamieniecka sheep (K) and its crossbreds (F,) with Berrichon du Cher (KxBCH) and Blackhead (K x B) rams before pre-slaughter handling and after slaughter were determined. No relationship between the Cortisol levels and the genotype of the animals were found. However, age-dependent differences in the concentrations of the hormone (P ≤ 0.01) were disclosed. In the group of 50-day-old rams, the level of Cortisol was 48.69 nmol/1 whereas in older animals it was 61.53 nmol/1. After handling and slaughter a significant increase in the hormone levels from 39.51 to 70.72 nmol/1 was found, presumably reflecting a pronounced stress response of the animal organisms.

The mean lipid and cholesterol contents of m. gastrocnemius were 3.87 g and 75 mg/100 g tissue, respectively. The overall profile of fatty acids of the muscle was found similar to ostrich meat. From dietetic and nutritive point of view fatty acids profile of nandu meat seems more desirable than those of the traditional avian species.

The effect of the level of maize distiller’s dried grains with solubles (DDGS) in diets for ducks and duration of the fattening period on feed efficiency, body weight, carcass and meat quality was studied. One hundred and sixty commercial Pekin ducklings were divided randomly into four groups (four replicates, each). From 1 to 21 days of age all birds received the same commercial feed, then from day 22 to 56 the ducks were fed with a diet containing one of four levels of DDGS (%): 0 (control), 15, 25 or 30. All ducks were weighed individually at 1, 21, 49 and 56 days of age and feed intake and feed efficiency were calculated. At 49 and 56 days of rearing, 10 birds with body weights close to the average weight for the group were chosen from each group, slaughtered and the following parameters were evaluated: weight of eviscerated carcass with neck, neck without skin, wings with skin, breast and leg muscle, edible giblets (heart, liver, gizzard), skin with subcutaneous fat, abdominal fat, remainder of carcass, as well as the physical and chemical characteristics of breast meat. Inclusion of maize DDGS in amounts up to 25% in the diet of ducks from day 22 of rearing had no adverse effect on the variables studied, regardless of age at slaughter. Moreover, it allowed decreasing the soyabean meal and wheat contents from 18.0 and 41.6% in the control feed to 10.0 and 24.1% in the 25% DDGS feed, respectively.

Целью соответствующих исследований была определение интенсивности прироста откормочников обеих пород и оценка их туш. Откорм проводился в период 100 дней осенью и зимой 1984/1985 гг. Опытный материал составляли 80 откормочников (по 40 голов каждой породы) сoдержимых в группах по 20 голов. Животные происходили от массового разведения. Данные касались материала 35 откормочных свиней пулавской и 23 свиней польской белой вислоухой породы, которые в определений период достигли предубойного веса. Откорм начался при весе тела 40 кг. Суточные привесы определяли в два периода: I-ый через 42 дня откорма, Il-ой через 99 дней откорма. Свиней подвергали убою в двух классах веса: 95 и 105 кг. Туши 24 пулавских откормочников (по 12 голов в классе) и 18 откормочников польской белой вислоухой породы (в том числе 10 голов с весом 95 кг и 8 голов с весом 105 кг) подвергали убойной оценке по методу SKURTCh. Установлены высокие темпы роста обеих пород. Среднесуточные привесы пулавских свиней в I-ый и II-ой период откорма были очень высокими (сответственно 760 и 723 г) и разнились высокосущественно от привесов свиней польской белой вислоухой породы (соответственно 715 и 556 г). Туши свиней польской белой вислоухой породы были длиннее и меньше менее ожиренными, имели более широкий глазох корейки и больше мяса в подлинном окороке (лучшее соотношение жир-мясо).
