The objectives of this study were to determine the effects of 2 dietary microbial additives on productive performance and feed efficiency when supplemented to diets of Holstein cows. One hundred seventeen Holstein cows were enrolled at 61 d (31-87 d) postpartum in a randomized complete block design experiment. Cows were blocked by parity group, as nulliparous or multiparous cows and, within parity, by pretreatment ECM yield.

Our goal was to investigate the effect of diets containing baleages harvested from alfalfa-grass or red clover-grass mixture on production performance, ruminal fermentation and microbiota taxa relative abundance, milk fatty acid profile, and nutrient utilization in dairy cows. Twenty Jersey cows (18 multiparous and 2 primiparous) averaging (mean ± SD) 148 ± 45.2 days in milk and 483 ± 65.

Background: Allergic rhinitis (AR) defined as inflammation and tissue remodeling of the nasal mucosa in atopic individuals after allergen exposure. Alpha-linolenic acid [cis-9, cis-12, cis-15-octadecatrienoic acid (18:3)] (ALA) as dietary supplementation can reduce inflammation and allergic symptoms.
Objective: To evaluate the potential therapeutic effect and mechanism of ALA in AR mouse model.
Effect of postruminal supply of linseed oil in dairy cows: 2. Milk fatty acid profile and oxidative stability.

Département des Sciences Animales, Université Laval, Québec, Québec, Canada G1V 0A6.
Our objective was to study the effect of increasing postruminal supply of linseed oil (L-oil), as a source of -9, -12, -15 18:3, on milk fatty acid profile and to assess the resulting impact on the development of volatile degradation products during the storage of homogenized milk. Five Holstein dairy cows fitted with a rumen cannula were randomly distributed in a 5 × 5 Latin square design. Abomasal infusion of L-oil was performed at the rate of 0, 75, 150, 300, and 600 ml/d during periods of 14 d.

Article Synopsis
- The study explored the use of Paulownia leaves silage (PLS) in dairy cow diets to assess its effects on ruminal fermentation, microbial populations, and greenhouse gas emissions, particularly methane.
- In vitro and in vivo experiments showed that adding PLS led to changes in ruminal fluid composition, including increased pH and volatile fatty acids while decreasing methane production by up to 14%.
- PLS also affected milk composition, resulting in lower protein and lactose yields, but did not significantly alter dry matter intake; it also modified fatty acid profiles in milk, indicating potential benefits for animal nutrition and environmental impact.
