Water Holding

Broiler chickens (Gallus gallus domesticus) were collected from local chicken suppliers of Dharan (26.8065° N, 87.2846° E), Nepal, and slaughtered to prepare the cut-up parts (breast, drumstick, dorso, wings, and thigh). They were vacuum packed in polythene bags and frozen stored (-21.5 ±3.5ºC) for 45 days to study the effect of frozen storage on the water holding capacity (WHC) of meat. Cooking loss, drip loss, and pH changes were analyzed at 5 days intervals during storage and the data were analyzed using Genstat® v 12.1.The cut-up parts showed a significant change (p<0.05) in pH, cooking loss, and drip loss during 45 days of frozen storage. The pH decreased while the drip loss and the cooking loss increased gradually upon storage. The pH was found to be varied among the cut-up parts with a minimum pH scale of 5.25 for wings, followed by 5.3 for thigh, at the end. The highest drip loss of 6.11% was observed in wings after 5 days of storage which ended up to 8.97% after 45 days of frozen storage while drumstick and thigh samples showed significantly lower drip loss of 6.02%, and 5.43% respectively. The change in cooking loss showed a similar pattern as that of drip loss with a significantly higher value of 37.36% in the breast while it showed no significant difference in drumstick, dorso, and thigh meat. Thus, the study reveals that freezing of broiler chicken meats for a prolonged period adversely affects the WHC of meat

Abstract The high level of ammonia and nitrite is a toxic factor for both poultry and aquaculture animals that directly lead to lower economic benefits. Thus, reducing ammonia and nitrite levels is an essential key for successful culture and is also important to reduce the amount of ammonia and nitrite released into the environment. This study aimed to screen bacteria having a capacity to degrade either ammonia or nitrite in vitro. Five bacterial strains previously isolated from broiler chicken (Gallus gallus domesticus) intestine and pond sediment of Nile Nilapia (Oreochromis niloticus) were used in this study, namely IBP-1, IBP-2, IBP-3, IBP-4, and IBP-5 strains. The screenings were performed using either NH4Cl containing medium or NaNO2 containing medium to determine the ability of bacteria to reduce ammonia or nitrite respectively. The ammonia and nitrite levels were afterwards measured at the beginning (day 0: before bacterial inoculation), 24h (day 1), 48h (day 2), and 72h (day 3) after the addition of 1 ml of the bacterial suspension. The results showed that the five bacterial isolates were able to degrade the ammonia and nitrite content. The greatest reduction of ammonia was achieved by IBP-4 strain (0.00 mg/l), followed by IBP-5 strain (0.04 mg/l), IBP-1 strain (0.05 mg/l), IBP-3 strain (0.14 mg/l) and IBP-2 strain (0.19 mg/l). IBP-1 and IBP-2 strains showed the highest reduction of nitrite levels with values of 0.01 mg/l and 0.02 mg/l after 72h of bacterial inoculation. These results suggest that the five bacterial strains are potentially used for degrading toxic ammonia and nitrite.

Pigment Accumulation

The black-bone chicken (Gallus gallus domesticus) is a breed of chicken that is commonly found in Thailand. This breed is known for having a number of black colored organs. Consumers have been notably attracted to the black-bone chicken breed for the characteristic darkness that is observed in many of its organs. However, the degree of darkness in all organs of the black-bone chicken is still in question. Importantly, there have not yet been any published reports on the distribution of melanin pigment in the organs of the black-bone chicken. This research study aims to examine the distribution of the melanin pigment in 33 organs of the Thai black-bone chicken. Ten black-bone chickens (five male, five female) were included in this study. Thirty-two organs including the brain, spinal cord, sciatic nerve, larynx, trachea, syrinx, lungs, heart, pericardium, aorta, brachial vein, kidney, cloaca, oviduct, testis, gastrocnemius muscle, femur, tongue, esophagus, crop, proventriculus, gizzard, duodenum, jejunum, ileum, cecum, pancreas, liver, gall bladder, omentum, abdominal fat, spleen, and skin were examined in this study. Histological sections taken from tissue samples of each of these organs were studied. The findings revealed that the presence of the melanin pigment was not significantly different (p > 0.005) between male and female specimens. Notably, the liver was the only organ in which the melanin pigment had not accumulated. Consequently, there was not a uniform pattern of melanin pigment accumulation throughout the organs of the chickens. The melanin pigment was present in all of the tissue layers of most organs, while the melanin pigment was found in only specific layers of some of the organs. In conclusion, the distribution of melanin pigmentation in the organs of each of the animals in this study was found to be different. However, in some tissue samples, such as those obtained from the liver, no accumulation of the melanin pigment was observed.
