Effect of β-mannanase, Lysolecithin and probiotic on some reproductive performance and hormone profile in female quail

Abstract

The aim of this study to evaluate the effect of β-mannanase. Lysolecithin and Probiotic on some reproductive performance and hormone profile in female quail. Six hundred one day-old quail birds were randomly divided to four treatments (60 birds/treatment) with 3 replicates for each group treatment (20 birds / replicate) and at three duration periods. The first period 1-7 weeks, second period 7-13 weeks, third period 1-13 weeks. The group of study were control was fed on a standard ration. the second, third and fourth treatments were given β-mannanase. Lysolecithin. probiotic 0.5 g /kg ration respectively. Blood samples wear taken for blood serum analysis. including estimation of follicle-stimulating hormone and luteinizing hormone. The results revealed that the treated groups showed a significant increase in relative weight of the ovary and oviduct compared with control group. β-mannanase and probiotic groups showed a significant increase in the oviduct length compared with the control and Lysolecithin groups. There was a significant increase in the numbers of growing and mature follicles and weight of large follicle in all treated groups compared with control group. The 3 rd period showed a significant increase in the relative weight of ovary. oviduct and numbers of growing follicles. while the 2 nd and 3 rd period showed a significant increase in the oviduct length. About the interaction between treatments and periods. the best result appeared in the ovarian relative weight in the 3 rd period for probiotic and β-mannanase. the 3 rd period of probiotic showed a significant increase in the oviduct relative weight and for the oviduct length at 2 ed and 3 rd period for probiotic and β-mannanase. while 3 rd period of probiotic show best interaction in the numbers of growing follicles, as 2 nd and 3 rd periods showed better increase in the mature follicle's numbers and for large follicle weight in 1 st and 2 nd period of probiotic. The result also showed a significant increase in the FSH and LH level in all treated groups compared with control group. The 2 nd and 3 rd period were better significantly in the level of FSH and LH. Probiotic at 2 nd and 3 rd period showed a significant interaction on the level of FSH. On the other hand, 2 nd and 3 rd period for the β-mannanase and probiotic showed a better significant in the LH level. In conclusion. β-mannanase. Lysolecithin and probiotic supplementation to quail ration improved the hormonal status and enhance reproduction.

Development of the wing bones in quail’s embryo; Coturnix japonica

“…Quail is not only an agricultural bird but also is one of the ideal vertebrate models used to study a variety of investigations (10). More recently, in third countries, this species has been housed as an alternative source of animal protein (11,12). There is much study regarding the prehatching skeletal development of Galliformes, and many authors did research concerning quail such as (13)(14)(15).…”

Impact of different artificial light intensities on some reproductive, productive performance aspects and blood picture of male quail

“…The initial body weight, final body weight, and total feed intake/quail and food conversion ratio (FCR) were recorded weekly, and the foam material from the cloacal glands weight was recorded (17). Foam obtained by each group of birds was collected and its weight was immediately calculated using a digital analytical balance (18).…”

Effect of dietary BHA supplementation on certain physiological values in broiler chicken

“…During previous years, different types of food additives were used in poultry rations, including probiotics, organic acids, and others, as (1) indicated that adding the probiotic and emulsifiers to quail diets at a rate of 0.5 mg/kg of feed led to an increase in the level of the FSH and LH, as indicated by (2) that adding organic acids to quail diet led to an elevated in the level of growth hormone. BHA is one of the additives used in poultry diets, but the references to study the physiological importance of BHA.…”
