Effect of feeding a commercial ammonia binding product De-Odorase™ on broiler chicken performance

Abstract

Ammonia production in commercial poultry sheds poses a problem for farmers as high levels can affect animal's respiratory health, resulting in hock and foot pad lesions and thereby affecting performance. A study was conducted to evaluate the suitability of whole, chopped and dried Yucca schidigera (De-Odorase™, Alltech Inc, USA) to reduce ammonia excretion from broilers and investigate the impact on broiler performance. Nine hundred and two, one-day-old Cobb broilers were randomly assigned to one of two diets, without (control) or supplemented with 500 g/t De-Odorase™. Birds fed the treatment diet had significantly higher body weight (P < 0.05) at 42 d and improved FCR (P < 0.05). Significant reductions in ammonia from litter were reported at 37 and 42 days old (P < 0.05 and P < 0.1, respectively). No significant differences were seen in foot pad, gait score, feather score or carcass data; although the birds fed De-Odorase™ had consistent numerical improvements in these parameters. The results of this study suggest that feeding whole, chopped and dried Yucca schidigera as a functional ingredient in the diet can be part of an ammonia management programme to improve broiler welfare and zootechnical performance.

Effect of Litter on Development and Severity of Foot-Pad Dermatitis and Behavior of Broiler Chickens

“…Litter amendments are often used in poultry production to reduce litter pH to control ammonia and as an intervention method in houses with a recurring disease issue such as gangrenous dermatitis (Shepherd et al, 2010). Results of other authors showed that litter treatments with chemical or microbiological products have positive effects on litter condition by lowering pH value (Madrid et al, 2012), reducing ammonia emission (Kim & Patterson, 2003;Iwaczuk-Czernik et al, 2007;Li et al, 2008;Madrid et al, 2012), or litter moisture (Iwaczuk-Czernik et al, 2007;Lazarevic et al, 2014). Such litter treatments might have a positive (decreasing) effect on FPD occurrence (Purswell et al, 2013).…”

“…Various litter amendments such as chemicals -aluminum sulfate (Madrid et al, 2012), sodium bisulfate (Nagaraj et al, 2007;Li et al, 2012), zeolite (Li etal., 2008), microbiological preparation (IwaczukCzernik et al, 2007), or a commercial ammonia binding agent (Lazarevic et al, 2014) are used to reduce litter moisture, pH and NH 3 emission in broiler houses. Some authors documented that such litter treatments might have positive effects on the occurrence of FPD (Nagaraj et al, 2007).…”

Evaluasi Penggunaan Silica+® sebagai Feed Additive terhadap Metabolisme Mineral, Status Kesehatan dan Kualitas Ekskreta Broiler

“…Emisi amonia adalah hasil dari proses fisik dan kimia yang kompleks, dengan tingkat emisi yang terkait dengan 4 faktor yaitu konsentrasi NH4 + , suhu internal, pH, dan efektivitas transportasi dari NH3 dari dalam metabolisme (Harper et al, 2010). Komplikasi dari paparan NH3 selama pemeliharaan unggas menyebabkan beberapa masalah antara penyakit pernapasan lainnya, kerusakan mata, lesi kaki, konversi pakan tidak efisien, penurunan Berat Badan, meningkatkan terjadinya penyakit Newcastle, keratoconjuctivitis, dan peningkatan jumlah Mycoplasma gallisepticum (Olanrewaju et al, 2008;Lazarevic et al, 2013).…”

Effect of straw size and microbial amendment of litter on certain litter quality parameters, ammonia emission, and footpad dermatitis in broilers

“…Various litter amendments, such as chemicals -aluminium sulfate (Zhang et al, 2011), sodium bisulfate (Nagaraj et al, 2007;Li et al, 2012) -dietary manipulations (Ferguson et al, 1998;Eichner et al, 2007), zeolite (Li et al, 2008), microbiological preparation (Iwańczuk-Czernik et al, 2007), and a commercial ammonia binding agent (Lazarevic et al, 2014), are used to reduce litter moisture, pH, and NH 3 emission in boiler houses. Litter treatments with chemical or microbiological products have positive effects on litter condition by lowering the pH (Zhang et al, 2011), and reducing ammonia emission (Iwańczuk-Czernik et al, 2007;Li et al, 2008;Zhang et al, 2011) or litter moisture (Iwańczuk-Czernik et al, 2007;Lazarevic et al, 2014).…”
