Growth performance and feed utilization of Hubbard Classic chickens fed on boiled and sundried mango (Mangifera indica Linn.) seed kernel

Abstract

An investigation was undertaken to study the effects of feeding boiled mango seed kernel (BMSK) on the growth performance and feed utilization parameters of Hubbard broiler chicks with the objective of recommending the optimum level of mango seed kernel inclusion in broiler feed. The experiment was arranged in a completely randomized design with four treatments, each replicated three times with 13 birds each. One-hundred fifty-six-day-old chicks with uniform body weight (BW) were used and were distributed randomly to the four diets. The four treatment diets were control (T1) (100% maize + 0% BMSK), T2 (95% maize + 5% BMSK), T3 (90% maize + 10% BMSK) and T4 (85% maize + 15% BMSK). All the experimental chickens were weighted initially (initial BW) and lasted for 49 days during which growth performance traits were recorded. After 49 days, two birds from each replication were randomly selected and slaughtered to evaluate the effect of BMSK on the final body weight of the chicks. The results on average daily feed intake per bird for T1 and T2 were not significantly different, i.e., 71.4 and 70.8 g (P>0.05) but it was significantly higher than that of T3 and T4 which was 68.13 and 68.23 g. At the end of 7 weeks, the final BW of chicks fed on T1 and T2 were 2657 and 2644, not significantly different, but were significantly higher than that of T3 and T4 which were 2610 and 2603 g per bird, respectively. The Average daily BW gain (ADG) for the respective T1 and T2 was 53.4, 53.2 g and was significantly (P<0.05) higher than that of T3 and T4 which were 52.44 and 52.31 g per bird. The feed conversion ratio (g feed/g gain) for T1 and T2 was 1.36, 1.36 and was significantly higher than that of T3 and T4 which were 1.33 and 1.33 g per bird, respectively. Inclusion of mango seed kernel up to 15% in broiler nutrition has no detrimental effect, profitable and can be best alternative feed sources in broiler feed if treated well by using the best technical methods of anti-nutritional factors like boiling.

Nutrient Content, Antioxidant Capacity, and Fatty Acids Profile of Cherry Laurel (Laurocerasus officinalis Roemer) Unshelled Kernel to Be Used in Poultry Nutrition

“…Beyene et al (2019) reported that mango kernels can replace maize entirely in laying hen diets, resulting in improved economic returns without impacting egg yield or quality parameters. Moreover, Beriso et al (2022) reported that incorporating up to 15% boiled mango kernel in Hubbard broiler diets can improve production performance and feed conversion parameters without adverse effects. Our results on nutrient content indicate the potential of the CLUK blend as a feedstuff is controversial for poultry nutrition due to the high ADF and NDF percentages in the CLUK blend.…”

“…Recently, because fruit residues, including shelled or unshelled kernels, are inexpensive, readily available, and include bioactive molecules, several studies have shifted to such residues as sources of antioxidants (Ibrahim et al, 2017;Jideani et al, 2021). Indeed, stone fruit kernels such as candlenut (Rohaida, 2014), grape (Karabacak et al, 2015), apricot (Orhangazi, 2017), date (Tareen et al, 2017), sour cherry (Gungor and Erener, 2020), and mango (Beriso et al, 2022) kernels have attracted great interest due to their potential for quality, healthy, cost-effective, and ecofriendly poultry production. All these studies have suggested that fruit processing by-products are effective and less expensive natural sources of bioactive compounds that exhibit significant antioxidant and synbiotic properties (Ibrahim et al, 2017;Jideani et al, 2021).…”

The Major Potential of Non-Conventional Feed Resources in Poultry Nutrition in Ethiopia: A Review

“…Because MSK is less expensive than maize and even other feed ingredients, there may be less competition for cereals in general and maize in particular between humans and chickens. Using MSK as chicken feed would help the poultry industry cut production expenses associated with expensive conventional feed [32].…”
