Quail Egg Yield and Quality of theCoturnix CoturnixResponse to the Addition Level of Agave Inulin to the Drinking Water

Abstract

To assess the effect of agave inulin addition to drinking water, one hundred (65 days old) Coturnix coturnix japonica hens were divided randomly into four groups with five birds per cage. Twenty five birds were assigned to each of the following treatments: i) control; addition of agave inulin in the drinking water at; ii) 2.0% (w/w), iii) 4.0%; and iv) 6%. The feeding trial lasted for six weeks. Inulin increased (P<0.05) weekly egg production by 13.35% and 10.73%, respectively as compared to the control. Feed consumption was reduced as the agave inulin in the water increased (P<0.05), but the water intake augmented (P<0.05). Circulating glucose averaged 193.29 mg/mL and was not statistically affected by the agave inulin the addition to the drinking water (P>0.05). The egg weight was similar among treatments (average 12.70 g) and varied slightly with the inulin level (P=0.0537). The egg shell (percentage of the egg) was not influenced by the inulin. But, the calcium concentration in the eggshell of the present trial varied with the level on the agave inulin in the drinking water (P<0.05). The yolk and albumin weight or percentage of the egg were similar among treatments (P>0.05). Then, the agav e inulin addition to the drinking water increases the egg yield of Japanese quails.

The effects of ad - libitum consumption of chitosan oligosaccharide with drinking water on laying quails

“…The fact that the quails were housed in optimum conditions in the present study may be the reason why chitosan olisaccharide did not have a statistically significant effect on the feed conversion ratio. Similar with the present study, Mora et al (2014), who gave inulin via drinking water to laying quails, reported that inulin had no effect on feed conversion ratio. However, contrary to the present study, dietary (2%) red seaweed (Sarcodiotheca gaudichaudii) (Kulshreshtha et al, 2014), 15 g / kg inulin diet (Shang et al, 2020) and different levels of mannanoligosaccharides diets (Jahanian and Ashnagar, 2015) positively effected the feed conversion ratio of laying hens.…”

“…On the other hand, another study with findings similar to the present study, showed that the effect of 200 and 400 mg / kg dietary chitosan oligosaccaride on egg weight was insignificant (Meng et al, 2010). When a series of studies on prebiotics were examined, different levels of mannan oligosaccharide (Bozkurt et al, 2012;Jahanian and Ashnagar, 2015;Ghasemian and Jahanian, 2016), yeast cell wall (Koiyama et al, 2018), inulin (Shang, 2010;Mora et al, 2014), xylo oligosaccharide (Li et al, 2017), red yeast rice (Sun et al, 2016), and seaweed polysaccharide (Guo et al, 2020) had insignificant effect on egg weight, which is in line with the present study. On the contrary, it is shown that dietary inulin obtained from different sources (Park and Park, 2012;Kulshreshtha et al, 2014;Shang et al, 2018) increases the egg weights of laying hens.…”

“…Similarly, the effect of different levels of inulin on the feed consumption of laying hens contradicts the research findings. While, some studies reported that inulin increases feed consumption (Park and Park, 2012;Shang et al, 2018), Mora et al (2014) declered that ad libitum administration of agave inulin to laying quails through drinking water did not affect their feed consumption. Besides, it has been reported that red yeast rice diet (Sun et al, 2016) and xylo -oligosaccharide diet (Li et al, 2017) as a prebiotic source have no effect on the feed consumption of laying hens.…”

“…Contrary to the research findings of the present study, just like yeast products, different levels of inulin (Shang et al, 2018) added to the diets of laying hens plus inulin oligosaccharide produced from Jerusalem artichoke (Helianthus tuberosus) (Park and Park, 2012) significantly increased egg production. It has been reported that all doses of inulin obtained from agave added to the drinking water of Japanese quails at the rate of 2, 4 and 6% increased egg production (Mora et al, 2014).…”

El 2% de inulina de agave en el alimento del conejo afecta positivamente la digestibilidad y microbiota intestinal

“…En general los azúcares del agave son usados principalmente para producir tequila y el fructo-oligosacárido inulina. Pérez de la Mora et al (2014) adicionaron ésta al agua de bebida de la codorniz japonesa, y mejoraron 10% la producción de huevo, con respecto al testigo; pero redujeron ligeramente el consumo ofrecido.…”
