Comparison of average daily gain, apparent digestibility, rumen fermentation parameters and bacterial communities, and serum antioxidant indices in Leizhou goats fed with or without rumen-protected fat.

Introduction: Rumen-protected fat (RPF) is a vital dietary energy source for dairy cows. However, the influences of RPF on rumen volatile fatty acid (VFA) content and bacterial communities in goats are poorly documented.

Methods: In this study, 12 castrated male goats (body weight [BW]: 13.

The Changes in Fecal Bacterial Communities in Goats Offered Rumen-Protected Fat.

Leizhou goats are famous for their delicious meat but have inferior growth performance. There is little information on rumen-protected fat (RPF) from the Leizhou goat. Hence, we observed the effects of RPF on growth, fecal short-chain fatty acids, and bacteria community with respect to Leizhou goats.

Magnolol supplementation alleviates diquat-induced oxidative stress via PI3K-Akt in broiler chickens.

This experiment was conducted to investigate the effects of magnolol on the oxidative parameters and jejunum injury induced by diquat in broiler chickens. This test adopts a 2 × 2 factors design, a total of 288 one-day-old male AA broiler chicks randomly allocated to four groups, consisting of six replicates of 12 birds each, which was then denoted as CON group, diquat (DIQ) group (16 mg/kg BW diquat was injected into birds at the age of 21 days), magnolol (MAG) group (basic bird diet supplemented with 300 mg/kg magnolol), and MAG + DIQ group. At 21 days of age, broilers in the DIQ group and the MAG + DIQ group were intraperitoneally injected with 16 mg/kg BW diquat.

Magnolol as a Protective Antioxidant Alleviates Rotenone-Induced Oxidative Stress and Liver Damage through MAPK/mTOR/Nrf2 in Broilers.

This study aimed to investigate the protective effects and molecular mechanism of magnolol supplementation on rotenone-induced oxidative stress in broilers. Two hundred and eighty-eight old male AA broilers were randomly divided into four groups: the CON group: basic diet with sunflower oil injection; the ROT group: basic diet with 24 mg/kg BW rotenone; the MAG + ROT group: basic diet with 300 mg/kg magnolol and rotenone injection; and the MAG group: basic diet with 300 mg/kg magnolol and sunflower oil injection. At 21−27 days of age, the broilers in each group were intraperitoneally injected with rotenone (24 mg/kg BW) or the same volume of sunflower oil.

Improved radar chart for lighting system scheme selection.

Lighting system scheme selection is an important part of infrastructure construction. This paper proposes an improved radar chart evaluation method for lighting system performance evaluation. First, to solve the problem of other weight scale methods' inaccurate calculation, Pitman's closeness measure in exponential form is used to determine the weight of the lighting system performance evaluation index.

Multi-Omics Analysis of the Microbiome and Metabolome Reveals the Relationship Between the Gut Microbiota and Wooden Breast Myopathy in Broilers.

Wooden breast (WB) is a widely prevalent myopathy in broiler chickens. However, the role of the gut microbiota in this myopathy remains largely unknown, in particular the regulatory effect of gut microbiota in the modulation of muscle metabolism. Totally, 300 1-day-old Arbor Acres broilers were raised until 49 days and euthanized, and the breast filets were classified as normal (NORM), mild (MILD), or severe wooden breast (SEV).
