This experiment was conducted to investigate the effect of in ovo feeding (IOF) and dietary feeding of Silybum marianum (SM) extract on the immunity of chicken under heat stress conditions. A total of 360 fertile eggs from a commercial broiler breeder (Ross-308) farm was used for in ovo feeding of 0, 100 and 200 mg/L SM water extract at day 17.5 of incubation. After hatching, 240 chicks were tr...

Drosophila ovo/svb (dovo) is required for epidermal cuticle/denticle differentiation and is genetically downstream of the wg signaling pathway. Similarly, a mouse homolog of dovo, movo1, is required for the proper formation of hair, a mammalian epidermal appendage. Here, we provide biochemical evidence that movo1 encodes a nuclear DNA binding protein (mOvo1a) that binds to DNA sequences similar...

The aim of this experiment was to study the effect of in ovoinjection of royal jelly (RJ) on growth performance and immune response in broiler chickens challenged with Newcastle disease virus. A total of 200 hatching eggs were divided into four groups of 50 eggs each one using a completely randomized design. The eggs were injected with sterilized sodium bicarbonate buffer (pH=10.4) or RJ (88%) ...

Early development of the digestive tract is crucial for achieving maximal growth and development of chickens. This study examined the effects of in ovo (IO) feeding of 0.70 mL of dextrose (10.00% and 20.00%) or amino acids solutions into the yolk sac at day 14 of incubation on small intestine histomorphometry and histomorphology, intestinal development, hatchability, body weight, and l...

“Ninguém nasce mulher: torna-se mulher”. Com a frase, Simone de Beauvoir apresenta o lugar delas como determinação social. No trabalho, pretende-se demonstrar essa ideia é apresentada na literatura brasileira. A partir da análise dos contos “Uma Galinha” e “O ovo Galinha”, Clarice Lispector, traçamos um caminho compreensão desse e, por meio uma abordagem simbólica Psicologia Analítica, ampliamo...

This experiment aimed to evaluate the effects of probiotic administration route (PAR),dietary nutrient density (DND) and Eimeria challenge (ECH) on performance, gut morphology, and hematological variables in broiler chickens. Eggs carrying 17.5-day-old broiler embryos were injected with 0.1 mL distilled water (vehicle control) or 0.1 mL distilled water containing probiotic. A group of ...

The Support Vector Machines (SVMs) had been showing a high capability of complex hyperplane representation and great generalization power. These characteristics lead to the development of more compact and less computational complex methods than the One-versus-Rest (OvR) and One-versus-One (OvO) [1] classical methods in the application of SVMs in multiclass problems. This paper proposes a new me...

Three allelic, dominant and germline-dependent female-sterile mutations (ovo(D) mutations) can be classified according to the severity of the ovarian abnormalities that they produce. The size and frequency of +/+ germline clones, induced in ovo(D)/+ females, were compared with K10/K10 germline clones induced in K10/+ control females. The frequency of germline clones induced by irradiation of fi...
