“…Similarly, previous studies also reported that shear force, cooking loss and pH are not affected by sex (Cisneros et al, 1996;Weatherup et al, 1998;Hamilton et al, 2000). In addition, Lee et al (2005) reported color and pH of longissimus dorsi muscle were not affected by the sex. While loin eye area is higher in gilts compared with barrows (p<0.05), which similarly agrees with Leach et al (1996) and Unruh et al (1996).…”

This study was conducted to investigate the effects of different energy intake on physical and chemical composition in body fractions, growth performance and meat characteristics of finishing barrows and gilts. A total of twenty six crossbred (Landrace× Yorkshire) consisting of 16 barrows and 13 gilts were used in this study. The animals were allocated by sex to two treatments to form a 2×2 factorial arrangement. The respective factors were sex (barrow and gilt) and dietary energy intake (1.8 and 3.0 times energy for maintenance). Pigs were kept in individual pens and had ad libitum access to feed and water from the start of the experiment at 52.4±1.9 kg until they reached 109.9±4.4 kg live weight. The growth performance, physical composition and meat characteristics of finishing pigs were not greatly affected by the sex. However, higher fat tissue weight in the carcass was observed in barrows compared with gilts (p<0.05). Higher proportions of water and protein (p<0.05), and lower lipid proportion (p<0.01) in the empty body and carcass were observed in gilts compared with barrows, while protein proportion in lean tissue was not affected by the sex. In fat tissue, only protein proportion was higher in gilts compared with barrows (p<0.05). Although, growth performance, physical and chemical compositions in body fractions were greatly affected, final body or carcass weight was partly affected by the energy intake In addition, loin characteristics such as shear force and loin eye area were partly influenced by energy intake levels. Therefore, the present results showed that growth performance and meat characteristics were not influenced but chemical body composition was greatly influenced by the sex. Growth performance, physical and chemical compositions in body fractions were greatly affected, whereas meat characteristics were partly affected by the energy intake levels.

“…The lipid content was low in even 1‐year‐old deer (2.0% FM) and female deer (2.1% FM) reared for a short period, like those in beef (1.19–3.62% FM) (Bureš & Bartoň ) and pork (2.28–3.76% FM) (Lee et al . ). According to Wiklund et al .…”

“…Higher levels of body fat and the fat content of meat in older males than in younger males in pigs (Berkshire) and beef cattle (Simmental × Charolais) have been reported (Lee et al . ; Bartoň et al . ; Bureš & Bartoň ), showing a different pattern from that of the age difference in our Yeso sika deer.…”

Yeso sika deer captured in winter around Lake Akan in Hokkaido were reared for 8-10 months at Tokyo University of Agriculture in Abashiri. Six 1-year-old females and males and six 2-year-old or older (adult) females and males were slaughtered and their carcasses were processed. The chemical composition, mineral contents and fatty acid composition of the loin were measured. No marked influence of gender or age was noted in the chemical composition of loin. In the mineral contents, significant differences were noted. The potassium and sulfur contents were lower and the sodium content was higher in adult deer meat (P < 0.05, respectively) and the potassium content was higher in male deer meat (P < 0.05). Arsenic, cadmium or lead were not detected. In the unsaturated fatty acid, a significant interaction was detected (P < 0.05), and it was high in 1-year-old female deer meat and low in 1-year-old male deer meat. Significant gender or age differences were noted only in the mineral contents in the loin of deer reared for a short period after capture.

“…This combination of low muscle pH and high muscle temperature can affect the ultimate meat quality by causing excessive denaturation of the muscle protein (Offer, 1991;Choi et al, 2006). Also, the muscle pH, temperature (Homer and Matthews, 1998), and final pork quality can vary between processing plants ( Van der Wal et al, 1999;Hambrecht et al, 2003;Lee et al, 2005;Gardner et al, 2006;Park et al, 2007).…”

The objective of this study was to investigate the effects of dehairing methods and sex on various traits of pork quality, as well as on tissue levels of the boar taint compounds androstenone and skatole. At the early postmortem period, dehided pigs showed higher muscle pH levels (p<0.05), lower temperatures (p<0.05) and lower drip loss (p<0.001) than scalded pigs. Thus, the dehairing method can affect the early postmortem glycolytic rate and water-holding capacity. Moreover, the differences in meat quality traits between the genders were small, and not considered to have practical importance. The scalding method had only a limited effect on the androstenone content. On the other hand, the scalded entire males exhibited a lower content of skatole than the dehided entire males (p<0.01). These results appear to indicate that the heating treatment from the scalding process influenced the reduction of skatole content for the scalded entire males.
