“…In the egg, the active form of vitamin D is supplied to the embryo by the yolk, acting on bone metabolism for skeleton formation. Thus, in ovo feeding in the embryonic period can positively influence bone growth in the first weeks of bird life, since, at this stage, the metabolism of bone tissue is intense, and failure to meet nutritional needs for this function will result in poor bone formation (Gonçalves et al, 2013).…”

Non-ruminantsFull-length research article In ovo feeding with 25-hydroxycholecalciferol influences bone mineral density of chicksABSTRACT -The purpose of this study was to determine if in ovo feeding with 25(OH)D3 could influence the incubation parameters of bone mineral composition, mineral density, and bone breaking strength in post-hatch broilers. Fertile eggs from Cobb ® broiler breeders were either non-injected or injected with 0, 1.2, 2.4, or 3.6 μg of 25(OH)D3/100 μL olive oil at eight days of incubation. The data were subjected to variance analysis using the General Linear Model procedure (GLM) of SAS ® . There was a contrast-1 effect (non-injected eggs vs. injected eggs) for tibial bone mineral density and egg mass loss, with higher bone mineral density in non-injected eggs (0.836 mmAl) compared with injected eggs (0.790 mmAl) and lower egg mass loss in non-injected eggs (11.25%) compared with injected eggs (12.10%). Tibial and femur bone mineral density responded quadratically, and injections of 0.47 and 0.68 μg of 25(OH)D3 increased tibia and femur bone mineral density, respectively. Egg mass loss responded quadratically, and 25(OH)D3 injections of 2.21 μg reduced egg mass loss (11.60%). In ovo feeding of 25(OH)D3 can compromise bone mineral density of post-hatch chicken.

“…Os ácidos graxos que são incorporados na gema são essenciais para o início do desenvolvimento da progênie. Na incubação de ovos de matrizes pesadas, cuja duração leva 21 dias, o terço final é o período mais intenso do metabolismo lipídico e rápido crescimento embrionário (Gonçalves et al, 2013). Estima-se que mais de 90% da necessidade total de energia para o desenvolvimento embrionário é derivada da oxidação dos ácidos graxos dos lipídios da gema.…”

O uso de lipídios na alimentação das aves é uma estratégia nutricional muito utilizada, pois contribui com o incremento energético, fornece importantes nutrientes para um equilíbrio nutricional e é a principal fonte de ácidos graxos poliinsaturados. Os poliinsaturados compreende as famílias de ácidos graxos ômega-3 e ômega-6. Onde seus principais representantes são os ácidos linoléico, alfa-linolênico, ácidos araquidônico e docosaexaenoico. Esses ácidos vêm sendo bastante estudados devido a suas diversas funções no organismo da ave reprodutora como: melhoria da qualidade do pintinho, enriquecimento do ovo, função anti-inflamatória, diminuição da gordura entre outros. Devido a esses benefícios vem se buscando o enriquecimento dos ovos com esses ácidos através da manipulação da dieta. Para isso tem sido utilizada diversas fontes lipídicas ricas em PUFAs n-3 como a linhaça, canola e óleos de peixes. O objetivo dessa revisão é abordar o efeito de diferentes relações do ácido linoleico (18:2 n-6) e alfa linolênico (18:3 n-3) na alimentação de aves de postura. A metodologia utilizada foi um estudo descritivo, baseada em artigos científicos publicados, resultando assim em um compilado de dados para essa revisão bibliográfica.

“…Artificial incubation is essential in the development of poultry production, since it represents the beginning of the production process and a key point in avoiding problems in post-hatching chicks [1]. The embryonic period of birds is a very important phase, as it represents a large part of their life; for example, a broiler lives, on average, 42 days and goes through an egg incubation period of 21 days until the hatching, which represents about 30% of the chicken's life [2].…”

The use of artificial lighting during the incubation phase is a tool that has been studied with the aim of increasing the production rates and hatchability. Using this, this study aims to investigate the effects of the luminous incidence of white and red monochromatic light on the production and metabolism of broiler chicks subjected to low temperatures. A total of 315 eggs of Ross 708 heavy breeders were used. The eggs were distributed randomly, with 35 eggs per tray, totaling 105 eggs per incubator. The treatments were the following: incubation without the use of light; the use of white monochromatic light; and the use of red monochromatic light. The lamps used were of the LED type. The samples were distributed in the factorial completely randomized experimental design with position effect on the tray. Candling, egg weighing, calculating the probability of survival and egg weight loss were performed. Temperatures were recorded using a thermographic camera. At birth, three chicks per tray were euthanized for evaluation: weight with and without yolk residue, gastrointestinal tract biometry, and blood and liver biochemistry. Analyses were performed using the R computational program. It was observed that there was a significant effect of the treatments on the levels of calcium, phosphorus, cholesterol, amylase, glucose, urea and glutamate pyruvate transaminase on the biochemical profile of the blood and on the thermographic temperatures of the eggs; the experiment was kept at low temperatures resulting in thermal stress, with an average temperature of 34.5 °C. Therefore, the use of red and white monochromatic light in the artificial incubation process for brown-colored eggs is not recommended, because in the post-hatching phase, it promoted the metabolism dysregulation on the blood biochemical profile to control the differentiation in the wavelength of traditional incubation.
