The results of studies of the chemical composition and physico-chemical properties of muscle and adipose tissues of pigs, obtained by combination of sows of large white breed with terminal and purebred boars of different genotypes.\u00a0According to the research results, the pH level of all meat samples ranging from 5,67 to 5,98 pH, which corresponding to normal. The highest acidity was recorded in the combination of large white x Maxter 16 – 5,98 pH units, which is 5.5% higher compared with the control.
\nIndicator tenderness of the meat of experimental animals indicates the effort that must be made to cut up the meat sample. The more tender the meat, the less time is required for its cutting (in seconds). In the obtained data the softer meat was combinations of large white x Landrace, large white x Maxter 16 and large white x Maxter 304, where the rates ranged from to 8.71 to 8.85 sec. The largest cutting length of the muscle fibers was in the combination of large white x Landrace x Duroc x Hampshire).
\nThe highest water-holding capacity was observed in animals of a combination of large white x pietrain – 63,06%, the lowest – large white x Landrace x Duroc x Hampshire) – 56,29. High water-holding capacity were recorded as combinations of large white x Maxter 16 and large white x Maxter 304 – 61,19 and 61,05 respectively.
\nAccording to the chemical composition of the meat found that lowest intramuscular fat of animals of differed combination of large white x Maxter 304 – 1.37 and Landrace x large white – 1,46, whereas in the group of large white x Maxter 16 this figure was amounted to 3.06.\u00a0The biological value of fat pigs are primarily determined by the content of unsaturated fatty acids. The highest melting point of fat in the samples of combinations of large white x Landrace and large white x Maxter 16, which represents that the increase of mass of saturated fatty acids and suitability of lard for long-term storage.\u00a0Thus, it is established that the chemical composition and physico-chemical properties of muscle and adipose tissues of pigs were at the level of normative indicators and meet the requirements of high quality products.<\/p>\n

\nThe results of the study of the chemical composition and physico-chemical properties of muscle and adipose tissue of pigs obtained by combining sows of Large White breed of purebred and terminal boars of different genotypes are given in the article.\u00a0It is established that the chemical composition and physico-chemical properties of muscle and adipose tissue of pigs were at the level of the standard indicators and meet quality requirements. However, the muscle tissue of animals of group IV the highest fat content \u2013\u00a03.06% and therefore the highest energy value \u2013 130 g kkal\/100. In investigated samples pH ranged 5\u2026.5.98 unit\u0456s pH. In the study of fat found in high melting point II and IV group \u201336.4 and 36.7\u00b0\u0421, respectively, indicating the suitability of fat for long-term storage.","protected":false},"excerpt":{"rendered":"
