Effect of graded levels of dry pineapple peel on digestibility and growth performance of rabbit

Abstract

Objectives: A feeding trial was conducted to investigate the effect of the inclusion levels of sun dried pineapple peel (PP) in the diets, on the digestibility and growth performance of rabbits. Methodology and Results: Diets R0 (control), R20, R30 and R40 were formulated by including 0, 20, 30 and 40% of PP. Panicum maximum C1 fodder supplemented the diet of each rabbit. Twenty-four growing rabbits, of 40 to 55 days old, with initial weight 765 ± 128g were used for 70-day trial. Faecal apparent digestibility of dry matter was measured in 12 rabbits during 7 days. The intakeof the diets based on PP was similar (p>0.05) to that in the control diet. Total feed intake ranged from 66 to 72 g DM/kg. The average dry matter digestibility (67.5%) was similar (p>0.05) in rabbits fed diet containing 20% PP and control diet. Average daily weight gain (15.5 to 16.7 g) and feed conversion ratio (5.48 to 6.08) were better in rabbits fed R0, R20 and R30 diets. Conclusions and application of findings: Results from this study show that weaned rabbits are good consumers of dried PP. This study demonstrated that, the dried PP is a suitable feedstuff for rabbits. It can be included in rabbits' diets up to 20% without a significant adverse effect on feed intake, dry matter digestibility and growth performance.The PP meal is biologically efficient and environmentally sustainable. It successfully enhanced the rabbit's growth performance. To get optimum performance of rabbit, famers may not exceed 20% inclusion level in dietary. However, the present technologies do not take into account other equal practices or more important, in farm conditions. Therefore, it is important to include the economical viability aspect in the technologies during on farm research before starting its dissemination.

Impacts of pineapple peel powder on growth performance, innate immunity, disease resistance, and relative immune gene expression of Nile tilapia, Oreochromis niloticus

“…Interestingly, significantly lower growth performances were found in fish fed high dose of PAPP. Similar results were observed in rabbits fed pineapple peel [62] and pig fed pineapple by-products [63]. This may be attributable to the high fibre contents in pineapple by-products.…”

The Possible Role of DL-Methionine in the Detoxification of Gliricidia Leaf Anti-nutrients in Rabbit Nutrition

“…The incorporation of GLM in the rabbit diets reduced the digestibility of dry matter (dDM), organic matter (dOM) and crude protein (dCP). The digestibility of dry matter (68.54 to 77.71%) observed is higher than values (62 to 67%) obtained by [30], [31] in rabbits, but lower than dry matter intake (77.62 to 85.99%) recorded by [32] [33]. The decrease of organic matter and crude protein digestibility with the inclusion of GLM in diet could be due to the presence of anti-nutritional factors which interfere with the utilisation of dietary nutrients in a various ways, including the reduction of protein digestibility, binding to various nutrients or damaging the gut wall [34] and thereby depressing digestive efficiency [35].…”

Assessment of feeding value of vegetable-carried pineapple fruit wastes to Red Sokoto goats in Ogbomoso, Oyo State of Nigeria

“…The observed crude protein was comparable to the value of 5.11% (Adeyemi et al, 2010) for pineapple peels alone, but higher than the value of 3.69% reported by Omwago et al (2013) for the waste. It was however lower than 6.12% reported by Aboh et al (2013) for pineapple peels. With the crude fibre content observed in this study, Omole et al (2011) opined that PW could be a veritable source of fibre in livestock diets.…”

“…The nitrogen free extract values reflect higher concentration of energy in PW than in WO and BDG in that order. Aside from compositional differences between the wastes, Aboh et al (2013) attributed the observed chemical variations in PW to pineapple varietal differences and supply of fertilizers.…”
