Feed intake, growth performance and carcass traits of broilers fed diets with various inclusion levels of baobab seed oilcake

Abstract

The effects of increasing dietary inclusion levels of baobab seed oilcake (BSOC) on the growth performance, carcass characteristics, and yield in Ross 308 broiler chicks were assessed. Dietary treatments (T) consisted of four levels of BSOC: T1, control (0% BSOC); T2, 5% BSOC; T3, 10% BSOC; and T4, 15% BSOC. Birds on T2 and T1 had the highest bodyweight (BW) on days 14 and 28, respectively. Feed intake (FI) was highest during the periods of 1 to 7 days and 15 to 21 days in T2 birds. From 15 to 21 days, Feed conversion ratio (FCR) was highest in T3 birds. Significant differences were noted in slaughter and carcass weights among the treatments. Although no significant differences were observed in dressing percentages among treatments, birds in T1 had a higher dressing percentage, followed by those on T2. There were no statistical differences in carcass yield among the treatments. Calculations for revenue and gross margin showed that feed costs were lower in T4 and higher in T2 in the starter phase. In in the grower phase, feed costs were lower in T4 and higher in T3. The gross margin was higher in T1 and lower in T2 in the starter phase. During the grower phase it was higher in T1 and lower in T4. It was concluded that the inclusion of 5% BSOC at most could improve growth performance. Additionally, increasing levels of BSOC reduced feed costs, with a reduction in the gross margin in the grower stage of broilers. ______________________________________________________________________________________

Growth Performance and Digestibility of Starter Broiler Chicks Fed Diets Containing Different Duration of Fermented Baobab (Adansonia digitata) Seed Meal

“…This result agrees with the findings of [23], [24] who reported no significant (p>0.05) difference in IW, FI, FW and FCR of starter broiler chicks fed differently processed roselle and baobab seed meal respectively. This study is contrary to the findings of [25], [26] who reportedly observed significant (p<0.05) difference in FI, FW and FCR of broiler chicks fed diets containing Roselle seeds fermented at varying durations and Baobab seed meal cake fed beyond 10% level of inclusion respectively. However, the variations may occur due to differences in grain legumes, seed processing and levels of inclusion respectively.…”

Immune response following Newcastle disease immunization and growth performance of kuroiler, broiler and local Tanzanian chickens

“…Also, the differences may be explained by feed content variations between the studies. For example, 4 weeks old broilers that were fed with feed supplemented with baobab seed oil cake had body weight of 1266 g, which is comparable to the broilers mean body weight of 1407.39 ± 25.12 g reported in the present study (Chisoro et al, 2018). Kuroiler is dual-purpose chicken raised for egg and meat production (Dessie and Getachew, 2016).…”

Incorporation of local novel feed resources in livestock feed for sustainable food security and circular economy in Africa

“…Second, it gives farmers an alternative way to make money since they can sell the leftovers or byproducts to companies that make premium livestock feed. Finally, it supports the circular economy idea, which calls for recycling refuse from one industry to create resource efficiency and reduce environmental impact (Chisoro et al, 2018;Jalal et al, 2023).…”

“…As shown in Figure 2, there will be continued consumption of meat and livestock products, since with the growth in population and income people will be more willing to spend more on better food products, which mostly tend to be meat-related. However, with the poor infrastructure around the African livestock sector, it is to some extent challenging to meet this estimated demand (Figure 2), since most contributors to the livestock sector in Africa tend to be rural and smallholder farmers, who either keep animals at a subsistence level or for retail in local communities through their butchery outlets (LDIA, 2014;Chisoro et al, 2019). Nevertheless, research seems to have found opportunities or to some extent options or ways that these farmers can use to enhance their production and contribute more to the African economy, especially the circular economy.…”

“…These studies are being conducted globally and with special attention to Africa, since Africa has a lot to benefit from this as a vast alternative resource, such as oilseeds from fruit-bearing trees, leaf meals from local trees, crop residues, food processing plants (candy producers, biscuit makers, potato chips manufacture, etc. ), insects, and agro-industry byproducts, which can be used in livestock feed and are readily available and sourced in Africa (Belluco et al, 2013;Negi and Pant, 2017;Chisoro et al, 2018;Nyamukonda and Ndlovu, 2019;Chisoro and Nkukwana, 2020b). The use of these local novel feed resources in Africa will significantly promote the growth of the livestock sector in Africa and allow it to meet its estimated consumption of meat and livestock products and the projected growth of livestock products, as highlighted in Figure 2.…”
