Application strategy for sustainable livestock production with farm animal algorithms in response to climate change up to 2050: A review

Czech Journal of Animal Science, 2022
Global warming caused by climate change can increase heat stress and greenhouse gas (GHG) emissions, leading to food problems and livestock crises. Thus, pre-emptive responses are required to mitigate the food problems and livestock crises. The potential

Evaluation of in ovo feeding of low or high mixtures of cysteine and lysine on performance, intestinal morphology and physiological responses of thermal-challenged broiler embryos

Frontiers in Physiology, 2022
The objective of this study was to evaluate the effect of in ovo feeding cysteine, lysine or their combinations on the perinatal and post-hatch physiological responses of broiler embryos exposed to heat stress during incubation.

Ovum in Ovo [PDF]

The American Naturalist, 1899
AN interesting case of egg within egg recently came to hand, which was unique in this respect: that the smaller enclosed egg lay in the yolk and not in the albumen of the surrounding egg, as in all similar instances hitherto recorded.' This hen's egg had unfortunately been cooked.

In Ovo Besleme

Hayvansal Üretim, 2017
Kuluckadan cikan civcivler asilama, cinsiyet ayrimi ve yetistirme kumeslerine nakillerinden dolayi 2-3 gun yem ve su tuketemeyebilirler ve civcivler sadece yumurta sarisindaki besin maddelerini tuketebilirler. Bu kuslarin ileriki donemlerdeki performansini olumsuz etkiler ve yetistiricinin kârinin azalmasina neden olur.

Expression Patterns of Copper/Zinc Superoxide Dismutase (SOD1) in Quail Embryonic Tissues Under in Ovo and Ex Ovo Conditions

Folia Veterinaria
Temperature fluctuations can act as stressors affecting embryonic development and cellular homeostasis. This study examined the effects of preincubation at 22°C (P22) or 30°C (P30) on quail embryos under in ovo and ex ovo conditions, focusing on the ...

Principles of ex ovo competitive exclusion and in ovo administration of Lactobacillus reuteri

Poultry Science, 1997
The data that have been presented indicate that the in ovo use of competitive exclusion (CE) agents is feasible for both chickens and turkeys. However, there are many pitfalls that await the use of in ovo application of CE agents, including the use of nonspecies-specific intestinal microbes and the use of harmful proteolytic, gas-producing and toxin ...
