Cashew reject meal in diets of laying chickens: nutritional and economic suitability

Abstract

The present study investigated the nutritional and economic suitability of cashew reject meal (full fat and defatted) as replacement for groundnut cake (GNC) in the diets of laying chickens. A total of eighty four brown shavers at 25 weeks of age were randomly allotted into seven dietary treatments each containing 6 replicates of 2 birds each. The seven diets prepared included diet 1, a control with GNC at 220gkg−1 as main protein source in the diet. Diets 2, 3 and 4 consist of gradual replacement of GNC with defatted cashew reject meal (DCRM) at 50%, 75% and 100% on weight for weight basis respectively while diets 5, 6 and 7 consist of gradual inclusion of full fat cashew reject meal (FCRM) to replace 25%, 35% and 50% of GNC protein respectively. Each group was allotted a diet in a completely randomized design in a study that lasted eight weeks during which records of the chemical constituent of the test ingredients, performance characteristics, egg quality traits and economic indicators were measured. Results showed that the crude protein were 22.10 and 35.4% for FCRM and DCRM respectively. Gross energy of DCRM was 5035 kcal/kg compared to GNC, 4752 kcal/kg. Result of aflatoxin B1 revealed moderate level between 10 and 17 μg/Kg in DCRM and GNC samples respectively. Birds on control gained 10 g, while those on DCRM and FCRM gained about 35 g and 120 g respectively. Feed intake declined (P < 0.05) with increased level of FCRM. Hen day production was highest in birds fed DCRM, followed by control and lowest value (P < 0.05) was recorded for FCRM. No significant change (P > 0.05) was observed for egg weight and shell thickness. Fat deposition and cholesterol content increased (P > 0.05) with increasing level of FCRM. The cost of feed per kilogram decreased gradually with increased inclusion level of CRM. The prediction equation showed the relative worth of DCRM compared to GNC was 92.3% whereas the actual market price of GNC triples that of DCRM. It was recommended that GNC could be completely replaced by DCRM in layer’s diets in regions where this by product is abundant. However, FCRM should be cautiously used in diets of laying chickens.

Replacement of soya bean meal with cashew nut meal as an alternative protein source in the diet of tilapia, Oreochromis mossambicus

“…The proper identification and detoxification of anti‐nutritional factors can enable the use of new plant ingredients in feed formulations. There are plenty of investigations carried out on cashew nut and its industrial by‐products in animal nutrition (Akande, Akinwumi, & Abegundi, ; Donkoh, Attoh‐Kotoku, Kwame, & Gascar, ). India is a major producer, processor, consumer and exporter of cashew in the world.…”

Growth response, cost benefit, carcass characteristics and organoleptic properties of pigs fed biscuit dough as a replacement for maize

“…In view of this, research efforts have been geared towards the search for available alternatives (Arowora and Tewe, 2003) including discarded cashew nut meal (Akande et al, 2015), Jatropha curcas seed and kernel meal (Oladunjoye et al, 2014;Ojediran et al, 2014), cassava peels, brewer's dried grain, rice husk, pineapple waste, palm kernel meal, sorghum spent grains, among others (Shittu et al, 2016). However, the attendant anti-nutritional factors, cost of processing and seasonal availability (Ojediran et al, 2017) of some of these alternatives have prompted the possibilities of using industrial wastes devoid of anti-nutrients such as biscuit dough.…”

Suitability of discarded cashewnut (Anacardium occidentale) meal as replacement of soybean meal (Glycine max) in the diet of juvenile African catfish Clarias gariepinus (Burchell, 1822)

“…Cashewnut (Anacardium occidentale) is an important crop with high export value and also a good plant protein and vitamin source (Akande et al, 2015). Cashew crop is indigenous to Brazil and was introduced to East and West Africa, India and Portuguese in the early 16 th century (Frankel, 1991).…”

“…Cashewnut is rich in protein and contains all the essential amino acids (Nambiar et al, 1990). It is available and can be accessed all year round (Akande et al, 2015).…”
