Topic Information

Dear Colleagues,

Feed and food production face issues related to animal welfare and sustainability. If, on one side, livestock-based food production is changing to maintain animal well-being, climate change is shifting dietary composition for animal production. Among the methods to improve animal welfare, a properly processed, with adequate nutrient levels, and non-contaminated diet will support gut function, decreasing locomotion problems caused by nutrient dysbalance as well as dysbiosis. Besides this, food-feed competition requires the selection of alternative nutrients, which should be produced with net-zero emissions. However, this change probably will demand feed additives to improve digestibility, e.g., enzymes, and should allow efficient growth of the livestock.

This Topic aims to provide the most up-to-date information about recent developments in livestock feeding to improve animal welfare without a negative impact on the environment. It covers a wide range of areas, highlighting the following main topics:

  • Alternative feed ingredients;
  • Feed processing;
  • Feed additives;
  • Gut health promotors;
  • Circularity;
  • Greenhouse gas emissions;
  • CO2 footprint.

N-carbamylglutamate (NCG) is postulated to improve fetal growth in nutrient-restricted gestations when supplemented from day 35 to 110 of gestation, but the effects of supplementation from 100 days of gestation to birth have not been evaluated. The aim of this study was to evaluate the effect of oral NCG supplementation from 100 days of gestation (dga) to term in naturally nutrient-restricted grazing twin-bearing ewes, on the maternal body weight (BW), body condition score (BCS), placental morphology, fetal body and organ weights and blood biochemistry and antioxidant status in the ewe and fetuses. Eighteen twin-bearing ewes maintained under grazing management were randomly allocated to either a treatment group (NCG; n = 10), orally dosed once daily with 60 mg/kg of NCG from day 100 until 140 dga, or an unsupplemented control group (CON; n = 8). At 140 dga, blood gases, redox status, maternal and fetal plasma and fetal biometrics were obtained after caesarian section. The serum concentration of NCG was increased 15-fold in the NCG ewes compared to the CON. No major effects on dam or fetal body weight nor on blood biochemistry or antioxidant parameters were observed. These results indicate that NCG supplementation in mid-to-late gestation to grazing ewes was unable to rescue the negative production effects of severe natural nutritional restriction on both the dam and fetuses.
