Effect of Species on Nutritive Value and Methane Production of Citrus Pulps for Ruminants

Abstract

The experiment was carried out to determine the effect of species on the nutritive value and methane production of citrus pulps. Species had a significant effects (P<0.001) on the chemical composition, gas production, methane production, metabolisable energy (ME) and organic matter digestibility (OMD) of citrus pulps. Crude protein (CP) content of Citrus paradise was significantly (P<0.001) higher than those of the other citrus species. Neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents of Citrus sinensis and Citrus reticulata were significantly (P<0.001) lower than the others. Methane production from Citrus reticulata was significantly (P<0.001) higher than those of Citrus limon and Citrus paradise. The ME of pulp from Citrus reticulata was significantly (P<0.001) higher than that of Citrus limon pulp whereas OMD of pulp from Citrus reticulata was significantly (P<0.001) higher than those of pulps from Citrus limon and Citrus paradise. As conclusion, citrus pulps from different species have a high potential as forage for ruminant animals since citrus pulps have high ME and OMD. However, the CP contents of citrus pulps should be taken into consideration and diets should be fortified with additional CP sources to compensate for the low crude protein when citrus pulps are included into ruminant diets.Keywords: Citrus pulp, nutritive value, metabolisable energy, organic matter digestibility, methane production Türün Narenciye Posalarının Besin Değerine ve Metan Üretimine Etkisi ÖzBu çalışma, türün narenciye posalarının besin değerine ve metan üretimine etkisini belirlemek için yürütülmüştür. Türün narenciye posalarının kompozisyonu, gaz üretimi, metan üretimi, metabolik enerji içeriği ve organik madde sindirim derecesi üzerinde önemli derecede etkisi vardır. Greyfurt posasının ham protein içeriği diğer narenciye posalarının ham protein içeriğinden önemli derecede yüksektir. Portakal ve mandalina posalarının NDF ve ADF içerikleri diğer posalardan daha düşük bulunmuştur. Mandalina posasının metan üretimi limon ve greyfurt posasının metan üretiminden daha yüksek bulunmuştur. Mandalina posasının metabolik enerji içeriği limon posasının metabolik enerji içeriğinden daha yüksek olasına rağmen mandalina posasının organik madde sindirim derecesi limon ve greyfurt posalarının sindirim derecelerinden daha yüksek bulunmuştur. Sonuç olarak, yüksek enerji ve organik madde sindirim derecesine sahip farklı türlerden elde edilen narenciye posaları kaba yem olarak ruminant hayvanların beslenmesinde önemli bir potansiyele sahiptir. Bununla birlikte narenciye posaları ruminant rasyonlarına katılırken ham protein içeriklerinin göz önüne alınması ve düşük protein içeriğinin telafi edilmesi için rasyonun protein kaynakları ile zenginleştirilmesi gereklidir.Anahtar Kelimeler: Narenciye posası, besin değeri, metabolik enerji, organik madde sindirim derecesi, metan üretimi

Impact of Substituting Corn Silage by Orange Pulp Silage on The Productive Performance and Economic Efficiency of Baladi Crossbred Calves

“…The observed values for DM were 29.79% and 20% for CS and OPS, respectively. These results were very close to those reported by [33] who mentioned that DM, OM and CP contents of OPS to be about 19.24, 95.04 and 7.86%, respectively. in the same trend, [34,35] who recorded OM and CP content in CS at 92,6% and 8,15 %, respectively.…”

Nutritive value and in-vitro digestibility of peels and pomaces of different citrus species

“…Furthermore, the in vitro dry matter digestibility studies carried out by Lashkari and Tagizadeh (2013) on bitter orange peels and pomace gave IVTDM values of 87% and 84.8% respectively. Also, several studies carried on the IVTDM of lemon pom- Gorinstein et al, 2001;Figuerola et al, 2005;Marín et al, 2007;Magda et al, 2008;Hon et al, 2009;Bejar et al, 2011;Atta and El shenawi, 2012;Ghanem et al, 2012;Lashkari and Tagizadeh, 2013;Palangi et al, 2013;Lashkari and Tagizadeh, 2015;M'hiri et al, 2015;El-ghfar et al, 2016;Nagarajaiah and Prakash, 2016;Özkan et al, 2017;Beyzi et al, 2018;Castrica et al, 2019) ace resulted in high digestibility values that ranged from 85.76%-91.2% (Trıpodo et al, 2004, Lashkari andTagizadeh, 2013). In addition, high IVTDM values within the range of 89.0%-90.6% were obtained for orange pomace from studies by Aregheore (2000), Tripodo et al (2004), Lashkari and Tagizadeh (2013), Alnaımy et al (2017).…”

Chemical Composition, Metabolisable Energy, Organic Matter Digestibility and Methane Production of Some Tannin Containing Forages

“…Although there are a lot of studies involved in chemical composition of forages there is a lack of information about condensed tannin and anti-methanogenic potential of forages. In vitro gas production technique is widely used to evaluate forages in terms of potential nutritive value, metabolisable energy and organic matter digestibility for ruminant animals (Kamalak et al, 2004;Kamalak et al, 2005;Ozturk et al, 2006;Kamalak et al, 2011;Ozkan et al, 2017;Atalay et al, 2018;Boga et al, 2020;Kamalak et al, 2021). It is well known that some anti-nutritive factors such as tannin and saponin decrease the enteric methane production from ruminant animals.…”
