Effects of yeast culture supplementation on lactation performance and rumen fermentation profile and microbial abundance in mid-lactation Holstein dairy cows.

open access: yesJournal of Dairy Science, 2021
The continuous trend for a narrowing margin between feed cost and milk prices across dairy farms in the United States highlights the need to improve and maintain feed efficiency. Yeast culture products are alternative supplements that have been evaluated

Fermented Bamboo Fiber Improves Productive Performance by Regulating Gut Microbiota and Inhibiting Chronic Inflammation of Sows and Piglets during Late Gestation and Lactation

open access: yesMicrobiology spectrum, 2023
Dietary fiber is widely applied in the nutrition of sows due to its potential value in improving performance and intestinal health. Fermented bamboo fiber, rich in dietary fiber, has not been fully evaluated to be used in sow diets. ABSTRACT Sows exhibit

Effects of rumen-protective γ-aminobutyric acid additive on lactation performance and serum biochemistry in heat-stressed cows

open access: yesFrontiers in Veterinary Science, 2023
In the context of global warming, heat stress has become one of the major stress factors limiting dairy cattle production. Although many methods have been explored to help cows mitigate the negative effects of heat stress during the hot summer months ...

Streptococcus dysgalactiae Isolates at Calving and Lactation Performance Within the Same Lactation [PDF]

open access: yesJournal of Dairy Science, 2007
The objective of the study was to investigate the association between early lactation Streptococcus dysgalactiae isolates and milk yield, somatic cell count (SCC), clinical mastitis, and culling in the same lactation. The 178 commercial dairy herds were randomly placed into 3 penicillin- or penicillin-dihydrostreptomycin-based dry-cow treatments and 3 ...

Intensive Nursing and Lactational Performance during Extended Lactation

open access: yesExperimental Biology and Medicine, 1968
SummaryIntensive nursing (6 pups/6 intact abdominal-inguinal mammary glands, and replacing all 16-day-old litters every 4 days with 12-day-old foster litters) failed to prevent significant declines in mammary DNA, RNA, and litter weight gains between days 20 and 36 of lactation.

Effect of active dry yeast on lactation performance, methane production, and ruminal fermentation patterns in early-lactating Holstein cows.

open access: yesJournal of Dairy Science, 2020
This study was conducted to examine the effect of active dry yeast (ADY) supplementation on lactation performance, ruminal fermentation patterns, and CH4 emissions and to determine an optimal ADY dose. Sixty Holstein dairy cows in early lactation (52 ± 1.

Production performance of Holstein cows at 4 stages of lactation fed 4 dietary crude protein concentrations.

open access: yesJournal of Dairy Science, 2022
Dairy cow responses to dietary crude protein (CP) may depend on stage of lactation. The primary objective of this study was to evaluate the effects of 4 concentrations of dietary CP on dry matter intake (DMI), production performance, net energy for ...
