Effects of Functional Feed Additives on Growth Influenced Hormones and Performance of Japanese Quails (Coturnix japonica)

Abstract

The objective of this research was to determine the effects of Protexin®, Fermacto® and its compounded effects on growth performance, visceral organs weight, insulin, thyroxin and growth hormone of Japanese quails. Growth performance with respect to body weight gain and visceral organs weight were recorded and then blood sampling were taken for analysis of serum hormones using ELISA technique. The analyzing of data in completely randomized design showed that consumption of each Fermacto® and Protexin®+Fermacto® caused elevation in feed intake and body weight (p<0.05). The gizzard weight in males fed Fermacto® was decreased and in females fed all additives, especially protexin® was elevated (p<0.05). Males and Females fed Fermacto® have lighter intestines weight than other additive groups (p<0.05). The heart weight in males fed additives were reduced and in females fed Protexin® were elevated (p<0.05). In males fed additives liver weight was lighter than control group (p<0.05). In females fed Fermacto® and Protexin® + Fermacto® liver weight was reduced (p<0.05). Insulin level increased (p<0.05) by feeding of Fermacto and Protexin®+ Fermacto® in female and males respectively. The level of thyroxin in females depressed by feed additive consumption (p<0.05). Growth hormone level was elevated by consuming of feed additives in female birds (p<0.05). It was concluded that consumption of each Fermacto® and Protexin®+ Fermacto® in quail's diet can improve growth performance values by increasing the feed intake and stimulating the insulin and growth hormone release.

Effect of supplementation of encapsulated organic acid and essential oil Gallant+® on some physiological parameters of Japanese quails

“…This result agreed with a previous work where a significant increase in the growth hormone was specified (21). The similarity to the findings of our study Hossein et al (22) showed that ingestion of both Fermacto ® and Protexin ® in quail feed could stimulate growth hormone secretion. Moreover, our result did not show a significant change in glutathione level between groups; this result disagreed with Farag et al (23) who found the relationship among antioxidants property of essential oils and its chemical composition.…”

Probiotics and Poultry Gut Microflora.

“…In addition, dietary intake of Kefir as a probiotics source resulted in a decrease in chicken liver weight (Vahdatpour and Babazadeh, 2016). Diet supplemented to Protexin® probiotic alone or in combination with Fermacto® prebiotic increased growth hormone level and improved growth performance in quails (Nikpiran, 2014). The administration of probiotic supplements via drinking water significantly improved the weight gain in Kenyan indigenous chicken (Atela et al, 2015).…”
