Yaks are one of the important livestock on the Qinghai-Tibet Plateau, providing abundant dairy and meat products for the local people. The formation of these dairy and meat products mainly relies on the microbiota in their gastrointestinal tract, which digests and metabolizes plant feed. The yak's gastrointestinal microbiota is closely related to the health and production performance of the host, but the molecular mechanisms of diet-induced effects in intensively farmed yaks remain to be elucidated.

Article Synopsis
  • The study explores how seasonal dietary changes affect the rumen microbiota of grazing yaks in high-altitude plateau areas, focusing on differences between cold and warm seasons.
  • It found increased levels of acetic acid and acetic/propionic acid ratios in yaks during the cold season, indicating significant variations in fermentation parameters.
  • The results emphasize the adaptability of yaks to seasonal diet shifts and suggest implications for improving yak husbandry practices.

Soybean meals (SBM) from different locations differ in their protein content, subsequently influencing their amino acid (AA) profile. In this study, standardized ileal digestibility (SID) of AA and growth or production performance were evaluated in pullets and hens fed SBM derived from soybean grown in Western Canada, primarily Manitoba (MB) labelled as A-, B- and C-SBM compared with that from Eastern Canada (Ontario, ON-SBM) and contained 38.3 ± 0.

Article Synopsis
  • - The study investigates how yaks on a plateau in northwest Yunnan, China, adapt their rumen microbial communities in response to different feeding strategies, notably intensive feeding versus natural grazing, amid low oxygen and cold conditions.
  • - Utilizing 16S rRNA and ITS sequencing methods, the research reveals significant shifts in the types and amounts of rumen bacteria between grazing and fed yaks, with intensive feeding enhancing the breakdown of dietary fiber and increasing energy extraction.
  • - Results indicate that while naturally grazing yaks show higher levels of certain beneficial bacteria, intensive feeding leads to a rise in non-fiber-degrading bacteria, resulting in elevated fatty acids and altered microbial diversity, suggesting a complex adaptation to dietary changes.

Objective: To investigate inflammatory responses to lipopolysaccharide (LPS) injection in layers.

Animals: 33 40-week-old laying hens were used.

Methods: 30 laying hens were divided into 2 groups: the first group was injected with 8 mg/kg LPS, while the second group was injected with sterile saline.

Background: There is a lack of nutrition guidelines for the feeding of omega-3 polyunsaturated fatty acids (PUFA) to laying hens. Knowledge as to whether the type and concentrations of α-linolenic acid (ALA) and/or docosahexaenoic acid (DHA) in the diet can make a difference to the birds' immune responses when subjected to a lipopolysaccharide (LPS) challenge is limited.

Objectives: The study was designed to determine the potential nutritional and health benefits to laying hens when receiving dietary omega-3 PUFA from either ALA or DHA.
