Effect of Dietary Betaine and Folic Acid Supplementation on Performance, Egg Folate Content and Egg Production of Japanese Quail
Authors
Abstract:
A study was conducted to investigate the effects of different betaine (BET) (0.0, 0.5 or 1.0 g/kg) and folic acid (FA) (0.0, 4.0 or 8.0 mg/kg) levels on performance, egg FA concentration and egg production of laying quails using 288 forty-two day-old Japanese quail in a 3 × 3 factorial arrangement of treatment based on randomized complete design. The results showed that none of the performance traits, except feed intake, was affected by dietary treatments. No effect of FA and BET supplementation was observed for egg specific gravity but egg shape index was affected throughout the experiment. No significant differences were observed for egg white, pH, weight and ratio, but Haugh unit (HU) was affected significantly by FA supplementation (P

Effect of dietary folic acid supplementation on egg folate content and the performance and folate status of two strains of laying hens.
Enrichment of eggs with folate is possible when dietary folic acid levels are increased. However, development of optimal strategies for the production of folate-enriched eggs requires knowledge as to differences due to strain of bird and a greater understanding of the factors limiting egg folate deposition. To this end, a study was designed to determine the response of two leghorn strains that ...

The research was conducted at Bangladesh Agricultural University Poultry Farm, Mymensingh to evaluate the effect of different levels and sources of calcium on egg production and egg shell quality of Japanese quail (Coturnix coturnix japonica) up to 23 weeks of age. For that purpose a total number of 108 Japanese quails aged 20 week were fed on diets containing different levels (2.5%, 2.75% and ...

The present study was conducted to determine egg production traits and egg quality characteristics in black and brown lines of Japanese quail. A total of 500 quails comprising 400 females and 100 males obtained from two breeding centers were raised according to the standard procedure for Japanese quail. They were grouped in according to their plumage colours. Age at first egg-laying has been re...

An experiment was conducted on laying quails to determine optimum dietary level of Ashwagandha supplementation on egg production and egg quality traits at Instructional poultry farm Nagla, GBPUA&T. Hundred quails were randomly distributed in four treatments and reared on standard managemental conditions. The root powder of Ashwagandha was added over the basal ration at 0.5% level (T2), 1% (T3),...

The study was conducted to determine the effect of varying protein levels and preservation method on external egg qualities of Japanese quails. A total of 180 birds were randomly allotted into three dietary treatments in a completely randomized design (CRD) replicated six times. A factorial arrangement of 3 × 4 × 4 which involves 3 protein levels (15, 20 and 25% crude protein), 4 storage method...

In this experiment, the influence of prebiotic and probiotic supplementation in the broiler breeder diets on body weight, mortality, feed intake, egg production, hatchability and humoral immunity response was investigated. A total number of 13140 female and 1260 male breeders (Cobb 500) with 26 wks of age were allocated to three treatments with six replicates (800 birds each replicate). Breeder...
