Free radicals, the result of the Respiratory process Free radicals are products from the respiratory process. They are highly reactive and can induce important oxidative damage in the organism, leading to an impairment of bio-logical functions. Antioxidants are defense molecules used by the animal to fight against these reactive species. They can be produced by …

A risk factor for sow breeding: Constipation Constipation affects between 20 and 30% of sows in intensive breeding. It is a risk factor for urinary tract infections, cystitis and pyelonephritis and can also cause dehydration and atrophy of intestinal villi, which in turn may facilitate bacterial, viral and parasitic infections (Ramonet et al., 2017). The …

The negative effects of coccidiosis on Gut Health Health in general and gut health more specifically, are important pillars of animal welfare. Gut health can be negatively affected in broiler chickens by coccidiosis. To limit the effect of this disease, coccidiostats have been used with success for decades. However, resistance is a side effect of …
Resistant and invading parasites: Red Mites Red mites are ectoparasites that live at the expense of laying hens. Their presence in laying farms has deleterious economic and health consequences. Their short life cycle and ability to survive without eating enable poultry red mites to proliferate, which makes them particularly difficult to remove from farms. Resistance …
Publication of a Peer Review Article In 2020, Doctor Sekhou Cisse (Nor-Feed, R&D Team) published a peer review article, in Transnational Animal Science journal, about the effect of the Standardized Natural Citrus Extract (SNCE; Nor-Spice AB®, Nor-Feed SAS, France) on the microbiota of the sows and on the weight gain of their piglets. Fifty sows …
Detrimental effects of heat stress in Livestocks Heat stress has detrimental effects in livestock. Excessive thermal stress around parturition can have detrimental effects on reproduction success and litter growth in swine. Antioxidants are commonly used in various species to limit oxidative stress caused by excess environmental heat. Grape polyphenols have been extensively studied for the …

What is Butyrate? Since the ban of 2006 on antimicrobial growth promotors (AGPs), the animal feed industry has been focusing on alternative strategies to improve gut health. In addition, to absorb nutrients the intestinal tract plays a key role in pathogen control and immune defenses, as long as its integrity is preserved. Butyrate is a …
