Performance and meat quality traits of slow-growing chickens stimulated in ovo with galactooligosaccharides and exposed to heat stress

Physiological effects of in ovo delivery of bioactive substances in broiler chickens

“…Further study needs to clarify this hypothesis ( 156 ). In addition, the supplementation of 3.5 mg Bi 2 tos on e12 did not reduce the negative effects of heat stress including breast muscle weight loss, increased feed conversion ratio, and reduced weight gain ( 182 , 183 ). Although in ovo supplementation has shown promise in improving various parameters during the post-hatch period, heat stress is a multifactorial problem and further research is needed to comprehensively define substances that can be used to mitigate the negative consequences of heat stress in chickens.…”

“…Management (cooling systems) and nutritional (high-fat diet, supplementation of osmolytes, vitamins, and minerals) strategies have been implemented to mitigate these negative impacts of heat stress on poultry ( 179 ). Recent studies have investigated the use of in ovo supplementation of bioactive substances to mitigate the negative impacts of heat stress in poultry, especially in broilers due to their fast-growing body and increased metabolic rate ( 156 , 180 – 183 ).…”

Effects of dietary supplementation of fermented Artemisia argyi on growth performance, slaughter performance, and meat quality in broilers

“…Although the L* value in the treatment group was higher than the control group, it was in the normal range. Meat with L* values (degree of paleness) higher than 54 is considered light and tends to be pale, soft, exudative meat ( Woelfel et al, 2002 ; Tavaniello et al, 2022 ). Diets supplementing with 1% fermented AA had no significant effect on b* value, while 3% unfermented AA group and 3% fermented AA group increased b* value within the normal range.…”

Embryonic modulation through thermal manipulation and in ovo feeding to develop heat tolerance in chickens

“…In this case, GOS supplementation during embryogenesis may act as a microbiome stimulator and protective agent to maintain intestinal integrity, decreasing the production of ROS, which is the most harmful sequel of HS. In another study, in ovo feeding of GOS on the 12th day of incubation did not affect the performance and meat quality of slow-growing broilers and showed higher resilience to enhanced temperatures ( Tavaniello et al., 2022 ). Meat quality cannot be ignored because it is a good source of animal protein used for human consumption.…”
