“…The second highest ratios was found in stearic acid (C18:0), that ranged from 22.3% at bulls from 500-580 kg weight group up to 22.9% at bulls 500-580 kg. BUREŠ et al (2006) SCOLLAN et al (2006) introduce the fatty acid composition at the level comparable to our results. The ratios of monounsaturated, di-and polyunsaturated fatty acids within Charolais beef is shown in table II.…”

FILIPČÍK, R., ŠUBRT, J., DUFEK, A., DRAČKOVÁ E.: The changes of fatty acids composition in beef of charolaise bulls slaughtered at diff erent weight. Acta univ. agric. et silvic. Mendel. Brun., 2011, LIX, No. 6, pp. 135-140 The aim of this work was to evaluate a slaughter weight infl uence (500-580; 581-640; 641-700 kg) of Charolaise bulls on intramuscular fat content and fatty acid profi le in musculus longissimus thoracis (MLT). The beef samples from 144 bulls were used to be evaluated. Statistically evidential (P < 0.05) diff erences in the intramuscular fat proportions (1.14 < 1.54 < 1.76%) in MLT samples were proved at all the weight categories of bulls. The highest average proportional ratio was determined in palmitic acid (C16:0), that ranged from 23.75% in bulls at 500-580 kg weight category to 24.79 % at 641-700 kg weight group. The lowest ratio of MUFA was in eicosapentaeonic acid (C20:1), its content ranged from 0.36% in the third weight group to 0.53% in 500-580 kg weight group. The highest MUFA ratio was in oleic acid (C18:1) at amount of 39.64% with diff erence ± 2.932%. The oleic acid ratio in beef rose up linearly according to the higher slaughtering weight (P < 0.01). Positive relation was proved between a slaughter weight and C18:3 a C22:5 PUFA content. The decrease of eicosapentaeonic and eicosadienoic acid was negative due to the essentiality for human health.

“…Considering both Bos taurus and Nfor et al Bos indicus animals, Bressan et al (2011) showed an effect of diet, pasture vs grain supplementation, but not of breed on protein content of beef. However the average protein content of beef (21.8%) was similar to the values previously reported by many other authors in Bos taurus breeds (Maher et al, 2004;Bureš et al, 2006;Piasentier et al, 2009;Corazzin et al, 2012). Effect of breed on fat content of beef was not statistically significant.…”

Aim of this research is to provide a general situation of cattle slaughtered in Cameroon, as a representative example for the Central African Sub-region. The quality and safety of beef from the abattoir of Yaoundé, the largest in Cameroon, were considered. From January 2009 to March 2012, the pre-slaughter conditions and characteristics of 1953 cattle carcasses were recorded, as well as the pH of m. longissimus thoracis 24 h after slaughter. From these carcasses, 60 were selected to represent the bulls slaughtered. The quality parameters and composition of m. longissimus thoracis were carried out. The origin of most of the cattle was the Guinea High Savannah (74.6%), and transhumance was the common production system (75.5%). Gudali (45.6%), White Fulani (33.3%) and Red Mbororo (20.3%) breeds were predominant. Carcass weight was affected by rearing system and cattle category, and it markedly varied during year. Considering meat quality, the fat content was low (1.2%) and similar between breeds, moreover Gudali showed the toughest meat. Of the cows slaughtered, 27% were pregnant and the most common abnormal conditions encountered were ectoparasites, fatigue, lameness, fungal-like skin lesions, enlarged lymph nodes, respiratory distress, nodular lesions. More than 20% of the carcasses had some organs condemned, mainly for liver flukes (5.17%), and 1.0% of them were completely condemned due to tuberculosis, that also affected 3.28% of lungs. These data could aid authorities draw up programmes with the aim to strengthen cattle production, improve beef supply, control and prevent the observed diseases, and promote the regional trade.

“…The lower dry matter content of MLL samples in the CH bulls in comparison with bulls of the other beef breeds was also reported in our previous study (Bureš et al, 2006). On the contrary, no differences in dry matter and protein content between Fleckvieh and Fleckvieh × Charolais bulls and heifers were observed by Velik et al (2008).…”

ABSTRACT:The effects of breed and diet containing different types of silages on meat quality parameters and fatty acid profile of m. longissimus lumborum (MLL) were evaluated in a total of 30 Czech Fleckvieh (CF), Charolais (CH) and Charolais × Czech Fleckvieh (CH × CF) bulls. The animals were fed two mixed diets: MS (based on maize silage) and LCS (based on legume-cereal mixture silage and lucerne silages) with different concentrations of dietary energy and fatty acids. The MLL from CH bulls had the lowest content of dry matter (P < 0.01), less protein (P < 0.01) and lighter meat (P < 0.01) compared to the CF. The extensive LCS diet reduced dry matter (P < 0.01) and intramuscular fat (P < 0.01) and increased the content of hydroxyproline (P < 0.05). The CH bulls exhibited higher PUFA n-3 (P < 0.05) and lower MUFA (P < 0.05) compared to the CF, with the CH × CF being intermediate. The LCS diet enhanced the proportions of PUFA (P < 0.05) and PUFA n-3 (P < 0.001) and reduced MUFA (P < 0.001). In conclusion, both breed and diet affected the meat quality and fatty acid profile of the intramuscular fat of the bulls. The replacement of maize silage with the legume-cereal mixture and lucerne silages in the diet reduced the concentration of intramuscular fat and improved its fatty acid profile from the human nutrition perspective.
