Effect of Yucca schidigera Spraying in Different Litter Materials on Some Litter Traits and Breast Burn of Broilers at the Fifth Week of Production

Abstract

SummaryThis study was carried out to determine the effects of different levels of Yucca schidigera spraying in different litter materials on some litter traits (moisture, pH, ammonia, total colony count, number of Enterobacteriaceae and number of yeast and mold) and breast burn of broilers at the 5 th week of production. A total of four hundred thirty two 1-d-old male broiler chicks (ROSS-308) were used. In this study 12 chicks were put in each pen having 170x94x90 cm (depth x length x height). Half of the litter was wood shavings, the other was rice hull. Yucca schidigera extract was pulverized weekly at the level of 0, 4% and 8% to each pen from the second week of the study. Litter materials and Yucca schidigera spraying at different level did not affect the examined litter traits and breast burns of broilers (P>0.05) at the 5 th week of production.

Haftasında Bazı Altlık Özellikleri ile Etçi Piliçlerin Göğüs Yanıkları Üzerine Etkisi ÖzetBu çalışma farklı altlık materyallerine değişik dozlarda ilave edilen Yucca schidigera'nın üretimin 5. haftasında bazı altlık özellikleri (nem, pH, amonyak, toplam koloni sayısı, Enterobakteri ve maya-küf düzeyleri) ile etçi piliçlerde göğüs yanıkları üzerine etkisini belirlemek amacıyla yapılmıştır. Bu çalışmada toplam 432 adet bir günlük yaşta erkek civciv (ROSS 308) kullanılmıştır. Çalışmada civcivler 170x94x90 cm (genişlik x uzunluk x yükseklik) boyutlarındaki bölmelerin her birinde 12 adet olacak şekilde yerleştirilmiştir. Altlık materyali olarak bölmelerin yarısında talaş diğer yarısında pirinç kavuzu kullanılmıştır. Her altlık grubu denemenin 2. haftasından itibaren her hafta altlığa 0, %4 ve %8 Yucca schidigera püskürtülecek şekilde 3 eşit alt gruba ayrılmıştır. Kullanılan altlık malzemelerinin ve altlığa değişik düzeylerde Yucca schidigera ilavesinin üretimin 5. haftasında incelenen altlık özellikleri ile etçi piliçlerde göğüs yanıklarını etkilemediği görülmüştür (P>0.05).

Effects of Yucca schidigera on gas mitigation in livestock production: A review

“…When YSE was applied to laying-hens, 100 ppm inclusion in diets significantly reduced ammonia emission by 44% and 28% for the first two days of manure storage 52 . However, an experiment showed that ammonia N concentrations and microorganism levels of litter materials (half was wood shavings, the other was rice hull) among examined groups did not show statistical difference when pulverized YSE was applied to different litter materials at the level of 0, 4% and 8% 53 . It was hypothesized that the efficiency of YSE could be amplified if litter was used in farming houses under bad situations 53 .…”

It was hypothesized that the efficiency of YSE could be amplified if litter was used in farming houses under bad situations 53 . As a study to evaluate the effects of YSE on poultry manure alone or together with microbial preparation, YSE showed highest potentials in reducing volatile odorous compounds concentrations after 96 h of the process 19 .…”

“…Factors such as different collection time correspond with varying degrees of manure moisture 52 , which need to be noticed to minimize the inaccuracy of experiment as well. Onbasilar et al 53 attributed the lack of effect in the experiment to exactly relatively low moisture and pH levels.…”

An assessment of the impacts of litter treatments on the litter quality and broiler performance: A systematic review and meta-analysis

“…Another unconventional treatment in the production of broilers is the use of Y. shidigera extract. Authors reported that there was no statistical difference in the values of pH, moisture and ammonia between litters treated with Y. shidigera extract and untreated litters [31].…”

“…Some litter treatments did not have more than one published article so they were excluded from the meta-analysis, namely: enzymatic biocatalyst (Rydall) and bacterial culture (Mizuho) [30]; Yucca Shidigera extract [31]; non-absorbent polymers [32] and biodegradable treatment [33]. Table 1 Shows the characteristics of the studies included in the meta-analysis.…”
