Abstract

This study evaluated the effects of Lactobacillus buchneri (LAB) and orange pulp (OP) supplementation on chemical composition, in vitro and in situ degradability, dry matter (DM), pH and aerobic stability of alfalfa silage. Treatments were 1) alfalfa without any additive (control), 2) alfalfa + OP (70% alfalfa mixed with 30% fresh OP, LAB0), 3) treatment 2 with 1.5 g LAB/ton (LAB1), 4) treatment 2 with 3 g LAB/ton (LAB2) and 5) treatment 2 with 4.5 g LAB/ton (LAB3). Treatments were replicated three times in laboratory mini silos for 90 d in a closed barn with a ambient temperature (15 to 18 oC). As a result of this study, the experimental treatments did not affect on DM of silage at the end of the ensiling period. Control treatment had the highest pH (4.5) among the experimental treatments ( P<0.05). Supplementation alfalfa with OP resulted in significant increase in water soluble carbohydrate (WSC) and total volatile fatty acids (VFAs) ( P<0.05). Treating alfalfa silage with OP and LAB improved aerobic stabilities of treatments significantly, as compared to LAB0. Supplementation of silage with OP and bacterial inoculant increased DM digestibility. These findings indicated that LAB can improve the aerobic stability and quality of silage in laboratory silos and also, OP and LAB might improve silage quality and cause better silage management in the farm.

Highlights

Improving rumen condition and production in livestock production farms is dependent on improving the conditions for digestion of the fiber (Jalc et al 2009; Hashemzadeh et al 2011,)

Summary

INTRODUCTION

Improving rumen condition and production in livestock production farms is dependent on improving the conditions for digestion of the fiber (Jalc et al 2009; Hashemzadeh et al 2011,). Yeasts that are able to metabolise lactic acid are the first cause of deterioration, which causes a rise in pH (Kleinschmit and Kung 2006; Jalc et al 2010), which is a stimulant for the growth of other harmful microorganisms in the silage (Sadegni et al 2012; Anonim 2016). These unwanted reduces livestock production due to food depreciation or poisoning. The results of the experiment were analyzed by oneway analysis of variance and treatment means were compared by the Duncan multible range test (SAS, 2002)
