Digestibility, productive performance, and egg quality of laying hens as affected by dried cassava pulp replacement with corn and enzyme supplementation

Abstract

Two experiments were conducted to investigate the potential use of dried cassava pulp (DCP) supplemented with enzymes as an alternative feed ingredient in laying hen diets. In experiment 1, 45 laying hens (Isa Brown) aged 45 weeks were placed in individual cages to measure nutrient digestibility for 10 days. Nine dietary treatments were control and DCP as a replacement for corn at 20, 25, 30, and 35% supplemented with mixed enzymes (cellulase, glucanase, and xylanase) at 0.10 and 0.15%. Results showed that the use of DCP at 20-35% added with mixed enzymes had no negative effects on dry matter digestibility, while organic matter digestibility and nitrogen retention decreased with increased DCP up to 30-35% in diets. Both enzyme levels (0.10 and 0.15%) showed similar results on nutrient digestibility and retention. In experiment 2, a total of 336 laying hens aged 32 weeks were randomly allocated to seven dietary treatments (control and DCP-substituted diets at 20, 25, and 30%) supplemented with mixed enzymes (0.10 and 0.15%). Diets incorporated with 20-30% of DCP and supplemented with mixed enzymes at both levels had no significant effects on egg production, egg weight, feed intake, egg mass, feed conversion ratio, protein efficiency ratio, or egg quality, except for egg yolk color being decreased with an increase of DCP in diets (P < 0.05). In conclusion, it is suggested that DCP supplemented with enzymes can be used as an energy source in laying hen diets up to 30% without showing negative effects on nutrient digestibility, productive performance, or egg quality.

Factors Affecting the Utilisation of Cassava Products for Poultry Feeding [Review]

“…In another study, [27] found that feeding 160 g/ kgAspergillus oryzae fermented CP had no effect on growth, carcass quality, nutrient digestibility and blood biochemistry of broilers. Khempaka et al [39]observed improved performance in laying hens fed 200 g/kg sun-dried CP diet and found a further improvement following enzyme addition [93]. During microbial fermentation, the protein content of CP increases and the fibre is broken down and this enables its utilisation by poultry.…”

A Review on Fungal Fermented Cassava Pulp as a Cheap Alternative Feedstuff in Poultry Ration

“…To elevate the dietary inclusion level of cassava pulp, supplementation of enzymes have been conducted. Khempaka et al (2018) have recently supplemented dried cassava pulp with mixed enzymes containing cellulase, glucanase and xylanase in laying hens. Such enzyme supplementation could increase the inclusion level of dried cassava pulp from 20% (Khempaka et al, 2016) to 30% (Khempaka et al, 2018) in laying hen diets.…”

The activity of enzymes in degrading the fibre fraction of cassava pulp may increase the digestibility of such feed ingredient and thus increase the feed intake of chickens (Khempaka et al, 2018).…”

“…Khempaka et al (2016) Dried cassava pulp can be included up to 20% in laying hen rations with no negative impact on productive performance, nutrient digestibility, and egg quality. Khempaka et al (2018) Dried cassava pulp supplemented with mixed enzymes (cellulase, glucanase and xylanase) may be included in laying hen feeds up to 30% with no detrimental effects on nutrient digestibility, productive performance and egg quality.…”

Bacillus coagulans TL3 Inhibits LPS-Induced Caecum Damage in Rat by Regulating the TLR4/MyD88/NF-κB and Nrf2 Signal Pathways and Modulating Intestinal Microflora

“…B. coagulans does so by promoting the secretion of digestive enzymes, thus producing a variety of metabolites by itself and by degrading polymer compounds. It also improves body's digestive function by improving the vitality of intestinal digestive enzymes [36,37]. It has also been shown that B. coagulans can degrade macromolecular substances via metabolic pathways in the body [38].…”
