The effect of dietary supplementation of salts of organic acid on production performance of laying hens

Abstract

Aim:An experiment was conducted to evaluate the effect of supplementing different levels of salts of organic acid in the laying hen’s diet on their production performance and egg quality parameters during a period of 16-week.Materials and Methods:A total of 140 white leghorn laying hens at 24 weeks of age were randomly distributed to seven dietary treatment groups, i.e. T1 (control), T2 (0.5% sodium-butyrate), T3 (1.0% sodium-butyrate), T4 (1.5% sodium-butyrate), T5 (0.5% calcium-propionate), T6 (1.0% calcium-propionate) and T7 (1.5% calcium-propionate) consisting of 5 replications of 4 birds each in each treatment and housed in individual cages from 24 to 40 weeks of age. Feed intake, percent hen-day egg production, egg weight, egg mass production, feed conversion ratio (FCR), and economics of supplementation of salts of organic acids in layers’ ration were evaluated.Results:The dietary supplementation of salts of organic acids did not significantly affect the feed intake (g/day/hen) and body weight gain (g). Different levels of supplementation significantly (p<0.05) improved production performance (percent hen-day egg production and egg mass production) as compared to control group. FCR in terms of feed intake (kg) per dozen eggs was lowest (1.83±0.05) in T4 and feed intake (kg) per kg egg mass was lowest (2.87±0.05) in T5 as comparison to control (T1) group. Salts of organic acids supplementation resulted in significant (p<0.05) improvement in FCR. Egg weight was significantly (p<0.05) increased at 0.5% level of salts of organic acids in the diet. The cumulative mean values of feed cost per dozen egg production were Rs. 44.14, 42.40, 42.85, 43.26, 42.57, 43.29 and 43.56 in treatment groups T1, T2, T3, T4, T5, T6 and T7, respectively, and reduction in feed cost per kg egg mass production for Rs. 0.52 and 0.99 in groups T2 and T5, respectively, in comparison to T1 group.Conclusions:It can be concluded that supplementation of salts of organic acids may improve persistency of lay, egg weight, and FCR. From economical point of view, egg production was more profitable at 0.5% level of sodium butyrate and 0.5% level of calcium propionate which reduced the feed cost per dozen eggs and per kg egg mass production without affecting the egg quality.

Effect of benzoic acid on production performance, egg quality, intestinal morphology, and cecal microbial community of laying hens

“…Hassan and Raheem (2016) also observed that feeding benzoic acid to broilers had no significant effect on body weight, weight gain, feed intake, and feed conversion ratio. While it has been reported that organic acid did not influence feed intake in laying hens ( Dahiya et al., 2016 ), it has been shown that organic acid can increase egg weigh ( Grashorn et al., 2013 ). The results of this study highlight the inconsistency of the responses to acidifiers which could be because of several factors including the buffering nature of some dietary ingredients and the heterogeneity of the gastrointestinal microbiota ( Pearlin et al., 2020 ).…”

Use of liquid vinasse as a feed additive for Japanese quails

“…However, Bahnas (2009) reported an increase in the laying rate of Japanese quail supplemented with 0.05% malic acid. Dahiya et al (2016) concluded that laying hens supplemented with salts of organic acids had higher hen-d egg production. Hidalgo (2009) reported an increase of up to 16% in egg production when birds ingested LV with the feed.…”

Yumurtacı Tavuk Rasyonlarına Katılan Organik Asitlerin Performans, Yumurta Kalitesi ve Bazı Kan Parametreleri Üzerine Etkisi

“…Bu çalışmada, hayvan materyali olarak 96 adet tüm aşıları yapılmış olan 28 haftalık yaştaki Lohmann (LSL) tipi beyaz yumurtacı tavuk, her biri 6 alt gruptan oluşan biri kontrol olmak üzere toplam dört gruba ayrılarak, tavuklar, her bir kafeste 4 tane olacak şekilde tam şansa bağlı deneme desenine göre üç katlı batarya tipi kafeslere (46 * 46 * 50 cm) yerleştirilmişlerdir. (Dahiya et al 2016) yemden yararlanma oranının iyileştiği rapor edilirken, yumurtacı tavuk rasyonlarına değişik seviyelerde propiyonik asit (Oruwari, 1993) ve farklı organik asit karışımlarının ilavelerinin (Kaya et al, 2013;Kaya et al, 2014;Gül et al, 2014) (Park et al, 2009). Organik asitler içerisinde en yüksek pKa değerine propiyonik asit sahip olduğundan dolayı gastrik pH üzerine daha etkili olduğu ve böylece yumurta kabuğunun en önemli minerali olan Ca absorbsiyonu iyileştirerek yumurta kabuk kalınlığını iyileştirdiği düşünülmektedir.…”

“…Günümüzde, yaklaşık olarak 60 adet organik asit (fumarik asit, malik asit, sitrik asit formik asit vb gibi) tanımlanmış (Park et al 2009) Bu çalışmadan farklı olarak yumurtacı tavuk rasyonlarına farklı seviyelerde organik asit karışımı (propiyonik asit, formik asit ve onların tuzları) ilavesiyle yürütülen bir araştırmada (Yeşilbağ and Çolpan, 2006) yumurta veriminin kontrole göre artırdığı, yemden yararlanma oranının doza bağlı olmamakla birlikte kontrole göre düştüğü ifade edilmiştir. Yine benzer başka bir çalışmada yumurtacı tavuk rasyonlarına kalsiyum propiyonat ilavesinin (Dahiya et al 2016) yemden yararlanma oranının iyileştiği rapor edilirken, yumurtacı tavuk rasyonlarına değişik seviyelerde propiyonik asit (Oruwari, 1993) ve farklı organik asit karışımlarının ilavelerinin (Kaya et al, 2013;Kaya et al, 2014;Gül et al, 2014) (Park et al, 2009). Organik asitler içerisinde en yüksek pKa değerine propiyonik asit sahip olduğundan dolayı gastrik pH üzerine daha etkili olduğu ve böylece yumurta kabuğunun en önemli minerali olan Ca absorbsiyonu iyileştirerek yumurta kabuk kalınlığını iyileştirdiği düşünülmektedir.…”
