Feasibility study of cassava meal in broiler diets by partial replacing energy source (corn) in regard to gross response and carcass traits

Abstract

Day-old unsexed broiler chicks (Cobb 500) were used to investigate the growth responses and meat yield traits by nourishing them under four dietary treatment group in inclusion of cassava meal with partial substitution of valuable energy source (maize or corn). A total of 260 birds were assigned randomly into four dietary treatments [T1 (0%); T2 (10%); T3 (20%), and T4 (30%)]; each replicated 5 times, 13 birds/replicate in a completely randomized design. Birds were reared with ad libitum feeding, similar housing, and environmental management condition from d1-35 days. Growth responses of broilers in terms of feed intake, body weight, feed conversion ratio (FCR), livability and meat yield traits were assessed in this study. Except for first week, the feed intake of birds on cassava treated diets up to 21 and 35 days was significantly (p<0.001) higher than the non-cassava or control diet (T1). Feed intake of broilers on cassava treated diet (T4 ) had the highest (2795.8 g/b) while the birds of control (T1) diet group consumed the lowest feed (2771.9 g/b) at 35 day. Live weight decreased (p<0.001) with the inclusion of cassava meal diets up to 21 day only; and live weights up to 7 and 35 days were identical between treatment. FCR up to 21 day was improved (p<0.001) on control diet (T1) and deteriorated on cassava treated diets. FCR values up to 7 and 35 days were unaffected by all the treatment groups. Neither the livability nor the meat yield traits (thigh, breast, drumstick, shank, neck, giblet, wing and dressing yield) of broiler chickens was influenced by the dietary treatments regardless of feeding broiler chickens with cassava or non-cassava diets in this study. It may be deduced based on the present findings that, cassava tuber meal might be a potential ingredient to replace the costly maize up to 300 g kg -1 without affecting growth performance of the broiler chickens.

An Assessment of Economic Sustainability and Efficiency in Small-Scale Broiler Farms in Limpopo Province: A Review

“…The key advantage of the poultry industry is that broiler rearing is not as capital intensive, and the birds can be efficiently produced within a short period compared to other animals [21]. The general public, regardless of rank or religion, prefers poultry, which has led to a dramatic rise in poultry imports into the nation and a steady growth in the demand for broiler meat [22]. For instance, during the 10 years between 2009 and 2019, South Africa's broiler meat consumption increased by around 25%, while broiler imports increased by The general public, regardless of rank or religion, prefers poultry, which has led to a dramatic rise in poultry imports into the nation and a steady growth in the demand for broiler meat [22].…”

Production performance and carcass characteristics of broiler treated with graded level of acetic acid

“…Broiler meat can rapidly and efficiently fulfil the shortage of protein requirements as it can be produced within a short time compared to that of other animals (Mbuza et al, 2017). The demand for broiler meat has been rising daily as most people, irrespective of caste and religion, prefer chicken (Hossain et al, 2011). Therefore, the number of poultry farmers on a commercial basis is being increased in Bangladesh (Kamruzzaman et al, 2021).…”

Financial and factor demand analysis of broiler production in Bangladesh

“…Besides, broiler meat can rapidly and efficiently fulfil the shortage of protein requirements as it can be produced within a short time compared to that of other animals ( Mbuza et al., 2017 ). The demand for broiler meat has been rising daily as most people, irrespective of caste and religion, prefer chicken ( Hossain et al., 2011 ). The percentage of broiler consumption in Bangladesh accounted for 40% of the total meat consumed in 2018, and per capita broiler meat consumption is 6.3 kg per year, which is expected to reach around 7 kg in 2020 ( WPSA-BB, 2018 ).…”
