Влияние стрессовой чувствительности свиней, выращиваемых в разных условиях интенсивной технологии, на биохимические процессы созревания и качество мяса

Влияние стрессовой чувствительности свиней, выращиваемых в разных условиях интенсивной технологии, на биохимические процессы созревания и качество мяса

Abstract

Growing up of stress-sensitive piglets in separate groups allows to obtain meat with higher content of glycogen, glucose and lactic acid than in groups grown with the mature pigs. It provides more intensive autolytic processes. During 10 days of storage the content of glycogen in meat reduces on 5,2 per cent, the concentration of glucose increases on 85,2 per cent, of lactic acid on 57,9 per cent, all that provides decrease of pH index on 20,9 per cent, comparing meat of stress-sensitive piglets grown together with stress-stable ones. Due to such character of hydrolytic process meat on the 2<sup>nd</sup> and 3<sup>rd</sup> day becomes mature with good properties of freshness, total organoleptic value of boiled meat and broth is good and may be given 7 points that is 3 points higher than in meat taken from stress-sensitive pigs grown together with stress-stable ones and 2 points lower if to value the meat of stress-stable animals.

Выращивание стрессчувствительных поросят в отдельных группах позволяет получить мясо с более высоким содержанием гликогена, глюкозы и молочной кислоты, чем у стрессчувствительных, выращенных вместе со зрелыми. Это обусловливает более интенсивное течение автолитических процессов. За 10 суток хранения в нем на 5,2 больше снижается содержание гликогена, повышается концентрация глюкозы на 85,2; молочной кислоты на 57,9%, что обусловливает более низкое значение показателя рН среды на 20,9%, чем в мясе стрессчувствительных, выращенных вместе с устойчивыми. Вследствие такого характера течения гидролитических процессов мясо на 2-3-е сутки становится зрелым с хорошими свойствами свежести. Общая органолептическая оценка вареного мяса и бульона хорошая и составляет 7 баллов, что на 3 балла выше, чем в мясе, полученном от стрессчувствительных животных, выращенных вместе с устойчивыми, и на 2 балла ниже относительно оценки мяса стрессустойчивых животных.
