Use of semi-leafless peas (Pisum sativum L) with enzyme addition in diets for broilers

Abstract

The aim was to study the effects of dietary pea inclusion and the addition of Avizyme 1200 -enzyme cocktail on broiler performance, intestinal viscosity and organoleptic quality of meat. The experimental design was a 4 × 2 factorial, the factors being dietary pea inclusion (0, 150, 300 and 450 g kg-1) in the diets fed from day 9 to day 38 and the addition of Avizyme 1200 enzyme cocktail including amylase, protease and xylanase during the entire experiment. The growth of birds improved (p ≤ 0.018) with pea inclusion in a cubic manner. Feed conversion ratio (FCR) of the birds fed on unsupplemented diets improved along pea inclusion, while pea inclusion impaired the FCR on the birds on enzyme cocktail supplemented diets (p ≤ 0.006). The use of the enzyme cocktail improved the body weight, body weight gain and FCR of the broilers and decreased intestinal viscosity (p < 0.001). The organoleptic quality of meat was similar among treatments (p > 0.05). In conclusion, 450 g kg-1 peas can be used in the broiler grower diets without negative effects on the bird performance. The use of enzyme cocktail improves bird performance.

Dietary fresh lemon improves the albumen quality, immune status and lipid metabolism of Jingfen laying hens during the late laying period

“…Several antibiotic alternatives, such as organic acids, probiotics, prebiotics and enzymes, have recently been reported to be beneficial for layers and broilers, as they improved weight gain (Haque et al 2010), feed conversion efficiency (Al-Sharafat et al 2009;Koivunen et al 2016), immune status (Al-Khalaifa et al 2019), carcase weight and carcase quality (Islam et al 2012).…”

Standardised Ileal Amino Acid Digestibility in Field Pea Seeds of Two Cultivars Differing in Flower Colour for Broiler Chickens: Effects of Bird Age and Microbial Protease

“…Another approach that has been considered as a means of attenuating the adverse effects of some ANF present in legumes is the dietary addition of exogenous enzymes [ 20 ]. However, several recent studies examining supplementation of diets containing raw pea seeds (30% or more) with xylanase-based carbohydrase complexes (‘cocktails’) have shown inconsistent effects on the performance and/or nutrient digestibility in broiler chickens, depending on the type of cereal grain (wheat or maize) used in feed formulation [ 7 , 21 , 22 , 23 ]. Despite direct and indirect evidence that supplementation with exogenous proteases may improve ingredient quality by reducing variability in proteinaceous feed materials and mitigating negative effects of trypsin inhibitors or lectins [ 24 , 25 ], there are only sparse data available on the effects of mono-component proteases on nutrient digestibility in broilers fed diets containing a considerable amount of peas [ 26 ].…”

“…В основном эффективность применения комбикормов с включением гороха изучена на бройлерах (9,12,15,18). Небольшая часть исследований посвящена применению этой культуры в кормлении несушек промышленного стада (6,16,17,19,20).…”
