Objective: This study aimed to assess the welfare conditions of broiler chickens in the live bird markets (LBMs) in Bangladesh. Materials and Methods: A total of fifty broiler outlets were studied in 10 LBMs of Chattogram, Bangladesh. A total of 10 chickens were observed to check the welfare issues during slaughter from each outlet (N = 500). The data were collected using a structured questionnaire method through interviews of the vendors and observation of the lairage and slaughter practice. Results: The study revealed that the stocking density was significantly higher in cage-type lairage than in floor-type (p < 0.05). The feeding and drinking areas for the chickens were significantly but negatively correlated to the stocking density. The duration between unloading of broiler chickens at LBMs and feeding or drinking could exceed 5 hours in 22% of outlets. The mortality was significantly higher in the bigger outlets than the smaller outlets (p < 0.05). During pre-slaughter han¬dling, the one-wing grasping method was practiced more in the bigger outlets (p < 0.05) whereas the feet grasping method was used more in the smaller outlets (p < 0.05). Moreover, the knives used to slaughter the chickens were not sharpened daily in 76% of outlets. Conclusion: This study indicated that the broiler chickens in the LBMs of Chattogram had to face many stress episodes at different stages at their penultimate moments—from lairage to slaugh¬ter—which led to poor welfare conditions and exacerbated the suffering of chickens.

Objective: This study assessed the impact of fermented Averrhoa bilimbi fruit filtrate (FF) on growth, gut morphology, and meat traits of high-stocked broilers. Materials and Methods: A 2 × 2 factorial trial with stocking densities (9 or 18 birds/m2) and drinking 2% FF or plain water was conducted using 378 14-day-old broiler chicks. On day 35, samples were obtained and analyzed. Results: FF improved feed efficiency and income over the feed cost of high-stocked broilers by about 7.63% and 10%, respectively, compared to high-stocked broilers receiving only water. FF decreased duodenal crypt depth and meat water-holding capacity. Meats from high-stocked broil¬ers receiving FF showed lower cholesterol than other meats. Lower cholesterol/high-density lipo¬protein (HDL) and higher HDL/low-density lipoprotein were found in meats from broilers receiving FF. Total unsaturated fatty acid (UFA) was higher in meats of high-stocked broilers receiving FF than others. The UFA/saturated fatty acid was lower in meats of high-stocked broilers receiving plain water. High-stocked broilers given FF had higher meat n-3 polyunsaturated fatty acid (PUFA). FF enhanced meat n-6 PUFA levels. The n-3/n-6 PUFA increased with high density and drinking FF. Conclusion: Drinking FF improved gut morphology and meat qualities of broilers housed in high-density pens. FF may be an excellent alternative to improve the growth and meat qualities of broilers raised in high-density houses. [J Adv Vet Anim Res 2022; 9(3.000): 536-545]

Objective: The study investigated the effect of different stocking density (SD) rates on the welfare, growth, and hemato-biochemical parameters in broiler chickens. Materials and Methods: 106 broiler chicks of 10 days old were used and assigned into four groups: A, B, C, and D. The chicks of group A were reared in floor space containing one bird per square foot area (SD1.0). The chicks of groups B, C, and D were reared at 1.5, 2.0, and 2.5 birds per square foot area (SD1.5, SD2.0, and SD2.5). Welfare, body weight, and hemato-biochemical parameters were assessed and monitored by physical observation and laboratory methods. Results: The birds reared at SD2.0, and SD2.5 rates showed increased panting breathing. Wet feces adhered below the vent. There were a significant number of birds showing dirtiness of body and feathers. Birds reared in SD2.5 were familiar with moist litters and high ammonia smell. Foot-pad dermatitis, scratches, and blister formation were detected in the leg. The study revealed that the higher SD negatively correlated to the welfare behavior indicators. Live body weight was significantly (p < 0.05) decreased in birds reared at higher SD rates. Birds housed in SD1.0 and SD1.5 are optimum for body weight and improved feed conversion ratio. The hemato-biochemical parameters of birds reared at various SD rates did not differ. The total leucocyte count increased significantly, while total serum proteins decreased gradually as SD rates increased. Conclusion: This work explores that higher SD negatively affects welfare and growth performance in broiler chickens. [J Adv Vet Anim Res 2021; 8(4.000): 642-649]
