“…Glycogen content of experimental quail was significantly increased in both skeletal muscles on d 14 and in the liver on d 42 of age. On the other hand, the biochemical indicators found in female Japanese quail of control group in the present study are in agreement with previous findings (Baumgartner 1990;Marks 1993;Yalcin et al 1995).…”

Hypodynamy is the most frequently used ground-based model to study the negative consequences of microgravity on an animal organism. The objective of the current experiment was to examine the influence of hypodynamy on the growth and development of the breast muscle, thigh muscles and liver in female Japanese quail chicks from 3 to 56 d of age. Samples of muscles and liver were obtained at 1, 14, 28, 42 and 56 d; the variables studied were: weight (g), relative weight (%), dry matter (mg/g) and content of total proteins, total lipids and glycogen (mg/g).The actual weight of breast muscle, thigh muscles and liver gradually increased with age of quail in both groups. However, the experimental birds exposed to hypodynamy showed a reduction in growth relative to age-matched control. At the end of testing, the body weight of the hypodynamy group was significantly lesser than that of control (P < 0.05). The control birds had also significantly heavier breast muscle than those of experimental group. Similarly, the dry matter and total lipid content in both muscles and liver of control group was significantly increased (P < 0.05). On the contrary, the differences in the content of total protein and glycogen in muscles and liver of both groups were not significant at the end of experiment.These results provide further evidence that, although hypodynamy affects the examined variables of selected skeletal muscles and liver, the female Japanese quail is able to develop under conditions of simulated weightlessness.

“…Sex differences for carcase traits in Japanese quail have been reported for breast yield and abdominal fat (Caron et al, 1990;Yalcin et al, 1995). A large reproductive organ in females, such as ovary and oviduct, is the main reason behind higher BW in females (Marks, 1993).…”

1. Estimates of heritability, genetic and phenotypic correlations of performance and meat quality traits were obtained in a population of Japanese quail using restricted maximum likelihood (REML) procedures. 2. The heritability estimates for body weight (BW) traits ranged from 0·15 at hatch to 0·42 at six weeks. For carcase composition traits, heritability estimates ranged from 0·12 for carcase yield to 0·26 for abdominal fat yield and for meat quality traits they ranged from 0·18 for drip loss to 0·54 for yellowness of the meat. 3. Negative genetic correlations were found between BW and carcase traits with ultimate pH and drip loss ranging from -0·01 (BW at hatch) to -0·40 (skin yield). Redness and yellowness showed negative genetic correlations with BW and carcase traits, whereas the genetic correlations with lightness were positive (from 0·04 to 0·43). 4. Shear force and cooking loss showed positive genetic correlations with carcase, breast, abdominal and skin yield. 5. In conclusion, meat quality traits have the potential to be improved through genetic selection but selection for higher BW and carcase composition may reduce the meat quality of Japanese quail through reducing redness, ultimate pH and intramuscular fat and increasing lightness, shear force and cooking loss of the meat.

“…Japanese quail are significantly more often used as experimental animals in scientific research. It was found that the weight, body conformation, and morphometry of internal organs of quail are influenced by many factors such as birds' age (Yalcin et al, 1995;Mihailov, 2006;Mihailov et al, 2008) and sex (Shata, 2001), type and composition of feed (Tarasewicz et al, 2007), type of feed additives (Aydin et al, 2004;Sarica et al, 2009;Bonos et al, 2010;Teshfam et al, 2011), rearing methods (Kul et al, 2006), stocking density (Abdel-Azeem, 2010) and ambient temperature (Özbey et al, 2004). Mihailov et al (2008) observed that the digestive tract of Japanese quail becomes morphologically and functionally mature between 7 and 14 days of age, after which the linear changes in the digestive tract are less significant.…”

“…Mihailov et al (2008) observed that the digestive tract of Japanese quail becomes morphologically and functionally mature between 7 and 14 days of age, after which the linear changes in the digestive tract are less significant. Meanwhile, Yalcin et al (1995) showed that age had no significant effect on the weight of digestive tract, gizzard, liver and heart. Other poultry species were also used to study how body weight, body conformation and the development of some organs are related to birds' age.…”

The effect of age of Pharaoh quail on body weight, body conformation and development of internal organs, including the digestive tract, was determined. At the age of 35 days, Pharaoh quail were characterized by significantly lower body weight, length of trunk with neck, and length of trunk compared to 45-day-old birds. Younger quail had slightly shorter breast bone and lower thighs, smaller chest girth, and the same length of shanks. Body conformation indices were significantly (P0.05) higher in 35-day-old birds. Pharaoh quail, evaluated at 35 and 45 days of age, did not differ significantly in the length of the oesophagus and crop, the length of intestine and its segments, and the weight and proportion of gizzard, proventriculus and heart. As birds aged, liver weight increased significantly, as did the weight and proportion of testicles in males.Keywords: Pharaoh quail, age, body weight, digestive tract Streszczenie Określono wpływ wieku przepiórek Faraon na masę i ukształtowanie ciała, rozwój narządów wewnętrznych, w tym przewodu pokarmowego. Przepiórki Faraon w wieku 35 dni cechowały się istotnie mniejszymi: masą ciała, długością tułowia z szyją i długością tułowia w stosunku do 45-dniowych ptaków. Młodsze przepiórki miały nieznaczne krótszy mostek, podudzia, mniejszy obwód klatki piersiowej i taką samą długość skoków. Indeksy ukształtowania ciała były istotnie (P0,05) większe u ptaków 35-dniowych. Oceniane przepiórki w wieku 35 i 45 dni nie różniły się statystycznie istotnie pod względem długości przełyku z wolem, długości jelita i jego segmentów oraz masy i udziału żołądka mięśniowego, żołądka gruczołowego i serca. Z wiekiem ptaków nastąpiło istotne zwiększenie masy wątroby, a u samców także masy i udziału jader.

W wieku 35 i 45 dni wybrano po 14 osobników o masie ciała zbliżonej do średniej populacji liczącej początkowo 90 sztuk. Przez cały okres badań (45 dni) ptaki przebywały w pomieszczeniu zamkniętym o regulowanych parametrach środowiska. Przepiórki żywiono ad libitum przemysłowymi mieszankami paszowymi. W 35. i 45. dniu ptaki zważono, a następnie zmierzono: długość tułowia z szyją, długość tułowia, długość grzebienia mostka, obwód klatki piersiowej, długość podudzia oraz długość skoku. Po przeprowadzonym uboju, odpierzaniu i patroszeniu wyodrębniono przewód pokarmowy i inne ważniejsze organy i narządy wewnętrzne. Przy użyciu taśmy mierniczej wykonano pomiary długości przełyku z wolem, jelita cienkiego, obu jelit ślepych, jelita końcowego, natomiast za pomocą wagi Medicat 160M określono masę wątroby, serca, żołądka mięśniowego, żołądka gruczołowego, a u samców dodatkowo jąder.
