Macroalgae Compound Characterizations and Their Effect on the Ruminal Microbiome in Supplemented Lambs.

The impact of macroalgae species on rumen function remains largely unexplored. This present study aimed to identify the biocompounds of the three types of marine macroalgae described: (Brown), spp. (Lettuce), spp.

Effect of multispecies fungal extract supplementation on growth performance, nutrient digestibility, ruminal fermentation, and the rumen microbiome composition of beef cattle fed forage-based diets.

Our objective was to evaluate the effect of a multispecies fungal extract (MFE) on growth performance, apparent total tract digestibility (ATTD), fermentation characteristics, and rumen microbiome composition of beef cattle fed forage-based diets. For experiment 1, ruminally cannulated Angus × SimAngus cows (n = 4; body weight [BW] = 569 ± 21 kg) were used in a randomized crossover design with two 21-d study periods and a 23-d washout period to evaluate the effect of dietary inclusion of a MFE on in situ digestion, ruminal fermentation, and the composition of the rumen microbiome. Treatments consisted of a forage-based diet with or without the inclusion of a MFE.

The effect of processing or concentration of dried distillers grain with solubles on the growth of finishing lambs.

Dried distiller grains with solubles (DDGS) are a popular byproduct used in the livestock feed industry as it is a cost-effective feedstuff that is rich in crude protein and minerals. However, a common concern related to the use of DDGS in livestock diets is the negative impact that affects animal dry matter intake (DMI) and growth. To further investigate this challenge, the experiments aimed to evaluate the effect of feeding 1) two different diets, control versus heat processed DDGS or 2) increasing the concentration of DDGS and its effect on body weight (BW), average daily gain (ADG), DMI, and gain to feed ratio (G:F) in finishing lambs.

Effect of supplementation to offspring during early gestation and the growing phase with different sources of fatty acids on learning and memory ability of postweaning lambs.

The objective of the current experiment was to evaluate the effects of supplementation with different dietary fatty acid profiles on the dam during the first third of gestation and on the offspring during growth on the offspring's cognitive behavior. Seventy-nine postweaning lambs were blocked by body weight and sex using a 2 × 2 factorial arrangement of treatments. The first factor (maternal supplementation; ) was supplementation to the ewes in the first third of gestation with 1.

Impact of Parenteral Maternal Supplementation with Trace Minerals and Vitamins on Neonatal Calf Antioxidant System and Growth in a Dairy Herd.

Oxidative stress may affect new born calves due to high stress suffered around birth. We hypothesized that maternal supplementation with micronutrients and vitamins in late gestation enhance the neonatal calf's antioxidant system, decreasing the occurrence and duration of diarrhea, and improving growth from birth through weaning. To test this hypothesis, 80 multiparous cows were cluster-assigned to treatment groups.
