Effect of Season on Performance of Broiler Chicken Under Deep Litter System of Management in Assam

Seasonal Impact on Growth Performance, Economic Feasibility, Hematological Indices, and Blood Biochemical Composition of Broiler Chickens

“…Also, the significantly higher (P < 0.05) livability percent for birds raised in the autumn, spring, and winter could be due to a more appropriate temperature for broiler chickens. By contrast, the low livability percent of broiler in summer could be due to heat stress and a lowered immune response, which can cause heatstroke, increased pathogens, and finally death (Sarma et al, 2019;El-Faham et al, 2017). However, the overall livability was above 95%, which is considered normal for broiler chickens.…”

Productivity and Profitability Estimates for <i>Sonali</i> Chicken Farms in Rajshahi, Bangladesh

“…Likewise, the costs of DOCs, rearing, breeding and medication for poultry farms in Pakistan were also higher in winter than in summer, but the price of broiler was lower in summer compared to that in winter [7]. Winter was the best season for the small-scale broiler farmers to earn profitability in terms of FCR, LW and BCR in all the selected poultry farms in Assam, India [8]. These are in good agreement with ours because seasonwise variations in DOC price, GR and BCR per bird were significant between the three farm sizes in Rajshahi.…”

“…Hence, seasonal variation adversely affects the performance and health of broiler chickens, like poor feed conversion and low-quality chicks. Traits such as body weight, sexual maturity and egg shape index [5], growth performance including body weight, feed conversion ratio (FCR) and feed intake [6], operational and medication costs and day-old chick prices [7] and body weight, FCR and livability [8] have been associated with seasons for poultry chicken rearing.…”
