“…In another experiment with Japanese quail slaughtered at 8 weeks of age, liver percentage was 2.06% in males and 3.52% in females (Aydin and Cook, 2004). Yannakopoulos et al (1990) found that liver percentage in 42-day-old Japanese quail was 3.50%. At the age of 45 days, Pharaoh quail had a lower percentage of gizzard than 35-dayold birds (Table 7).…”

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.

Ecological soil-screening levels (Eco-SSLs) were developed by the United States Environmental Protection Agency (USEPA) for the purposes of setting conservative soil screening values that can be used to eliminate the need for further ecological assessment for specific analytes at a given site. Ecological soil-screening levels for wildlife represent a simplified dietary exposure model solved in terms of soil concentrations to produce exposure equal to a no-observed-adverse-effect toxicity reference value (TRV). Sensitivity analyses were performed for 6 avian and mammalian model species, and 16 metals/metalloids for which Eco-SSLs have been developed. The relative influence of model parameters was expressed as the absolute value of the range of variation observed in the resulting soil concentration when exposure is equal to the TRV. Rank analysis of variance was used to identify parameters with greatest influence on model output. For both birds and mammals, soil ingestion displayed the broadest overall range (variability), although TRVs consistently had the greatest influence on calculated soil concentrations; bioavailability in food was consistently the least influential parameter, although an important site-specific variable. Relative importance of parameters differed by trophic group. Soil ingestion ranked 2nd for carnivores and herbivores, but was 4th for invertivores. Different patterns were exhibited, depending on which parameter, trophic group, and analyte combination was considered. The approach for TRV selection was also examined in detail, with Cu as the representative analyte. The underlying assumption that generic body-weight–normalized TRVs can be used to derive protective levels for any species is not supported by the data. Whereas the use of site-, species-, and analyte-specific exposure parameters is recommended to reduce variation in exposure estimates (soil protection level), improvement of TRVs is more problematic.
