Diet matrix of stored proprietary feeds: Implications on growth response, health status and carcass yield of broiler chickens

Abstract

This study examined growth responses, health status and carcass yield of broiler chickens from 22 to 42 days of age provided with proprietary finished feeds (4 brands; P, Q, R & S) exposed to two storage conditions (lit or dark room) for four weeks. Four hundred and eighty chicks (802.7±14.3 g), at 21-day-old, were randomly allocated to eight groups of 60 chicks each (6 replicates; 10 birds each). Broiler chickens were fed one of the eight resultant diets from storage exercise for 21 d. Results revealed that performance of finishing broiler chickens were influenced by both the main and interaction effects of feed brands and storage condition. Chickens fed feeds stored in dark room gained 5.39% heavier weight with better FCR (5.07%) and higher (P<0.001) crude fat (2.97%), protein (2.36%), fibre (2.43%) and ash (3.89%) digestibilities compared to birds fed feeds stored in lit room. Chickens fed with feed R had higher (P<0.05) PCV, RBC, total protein, albumin, and uric acid. Duodenal and ileal villus height (VH) and villus to crypt ratio (VCR) were higher in broilers fed feed R stored in dark room, whereas jejunal VH and VCR were higher in birds fed feed Q stored in dark room. Salmonella and lactobacillus counts were greater in birds fed feeds R and S stored in lit room, respectively. Higher (P=0.008) dressed yield was obtained in broilers fed feed S stored in lit room. The study revealed that exposure of similar or different finished feeds to varying storage conditions would impart broiler's performance differently.

Impacts of the COVID-19 Pandemic on the Production Costs and Competitiveness of the Brazilian Chicken Meat Chain

“…In India, losses exceeded USD 3.035 million, among other dramatic impacts on specific territories (Biswal et al 2020). Similar effects of the pandemic have been reported in Nigeria (Fafiolu andAlabi 2020), Egypt (Abu Hatab et al 2021), Ghana (Obese et al 2021), and Myanmar (Fang et al 2021). The impact of the pandemic has also been reported on energy supplies in China (Wu and Ma 2021) and other G7 countries (Awan et al 2021), on macroeconomic indicators such as inflation in China (Feng et al 2021), and on the supply chain for chicken feed (Attia et al 2022).…”

How consumers’ motivations and perceptions shape consumption of domestic products in COVID-19 era: A case of poultry meat in Ghana

“…Therefore, our study on how consumers' motivations and perceptions shape the consumption of local chicken in the COVID-19 era is warranted and fills the gap between Cranfield (2020), Attia et al (2022), Shahbaz et al (2022) andBen Hassen et al (2021). A review of existing studies in Bangladesh (Rahman et al, 2020), India (Biswal et al, 2020), Indonesia (Surni et al, 2020), Nigeria (Fafiolu & Alabi, 2020), and Ghana (Obese et al, 2020) showed that COVID-19 has affected the importation of livestock products, with the associated effect of lowering consumption, especially in Ghana.…”
