Arthrospira (Spirulina) Platensis Can Be Considered as a Probiotic Alternative to Reduce Heat Stress in Laying Japanese Quails
Provedor de dados: 89
Autores: Hajati,H; Zaghari,M; Oliveira,HC.
ABSTRACT This study was conducted to investigate the effects of Arthrospira platensis (Spirulina platensis, SP) on feed intake, feed conversion ratio, egg weight, hen day egg production, intestinal microflora, heat stress biomarkers, and HSP70 gene expression in laying Japanese quails (Coturnix coturnix japonica) suffering heat stress condition. A total of 250 female quails were allocated to 5 treatments, 5 replicates and 10 birds in each replicate in a completely randomized design. Experimental treatments included: 1) basal diet, 2) basal diet+ 0.03 % probiotic, 3) basal diet+ 0.1 % SP, 4) basal diet+ 0.3 % SP, 5) basal diet+ 0.5 % SP. During the last 6 days of the experiment, the quails were exposed to 8h of 34±1°C. The birds had free access to feed and...

Crude protein equivalence value of a multi-enzyme product for 28- and 42-day-old broilers
Provedor de dados: 89

In order to estimate the crude protein (CP) equivalence value of Natuzyme-p (NP) enzyme by using regression response equations, two experiments were carried out using Ross (308) broiler chicks. Graded levels of dietary CP (while amino acids levels were kept constant) and NP enzyme were used to derive the regression equation in the first experiment. Four levels of dietary CP and NP enzyme were fed to 160 feather-sexed male broiler chicks during the starter (0-28 d of age) and grower (28-42 d of age) period. Each diet was offered to four replicates of five chicks in a completely randomized design. Results obtained in experiment one failed to fit a regression equation between BW, dietary CP levels and NP enzyme. In experiment two, graded levels of CP changed...

Increased iNOS gene expression in the granulosa layer of F1 follicle of over-fed and under-fed broiler breeder hens
Provedor de dados: 89
Autores: Sheikh Ahmadi,A; Zaghari,M; Shivazad,M; Hassanpour,H; Towhidi,A.
To clarify the effects of high (20 and 40% more than normal) and low (20% less than normal) daily feed allowance on egg and body parameters, ovarian morphology and plasma glucose, cholesterol, triacylglycerol, leptin-like hormone, nitrite/nitrate and gene expression of inducible nitric oxide synthase (iNOS) in the granulosa layer of F1 follicle, broiler breeder hens (30-week-old) were fed for 30 days. Egg and body parameters significantly changed between treatments (p&lt;0.05). Effect of different level of feed intake on ovarian morphology parameters was significant (p&lt;0.05), except for white follicles. After 30 days of experiment, plasma nitrite/nitrate (as a index of plasma nitric oxide) and leptin-like hormone increased in FI+20% and FI+40% groups as...
