Precocious mammary development in an 8-month old Holstein heifer [PDF]

, 2008
— An 8-month-old, virgin Holstein heifer with precocious mammary development was presented for examination. Protein, fat, and lactose in the mammary secretion were 14.90%, 0.12%, and 0.20%, respectively; somatic cell count was 3.9 3 10 6 /mL, with no ...

Maternal gastrointestinal microbiome shapes gut microbial function and resistome of newborns in a cow-to-calf model

Microbiome
Background The maternal gut microbiome is the direct and important source of early colonization and development of the neonatal gut microbiome. However, differences in unique and shared features between mothers with different physiological phenotypes and

Nitrogen Flows, Nitrogen Use Efficiency, Nitrogen Footprint and Mitigation Strategies in a Large-Scale Dairy Farm: A High-Resolution Case Study in China

Agriculture
Large-scale dairy farms with anaerobic digestion (AD) are expanding rapidly in China, yet high-resolution assessments of N flows, N use efficiency (NUE), and N footprint remain limited.

The “costly son” hypothesis: Sons exacerbate obstetrical dilemmas in humans and other mammals

The Anatomical Record, EarlyView.
Abstract Human childbirth has often been considered uniquely difficult among mammals, yet recent evidence suggests that obstructed labor and fetopelvic disproportion are widespread across placental mammals. Here, we propose the “costly son” hypothesis: because male offspring are typically larger at birth, they impose greater obstetric risk on mothers ...

Balancing Environmental Mitigation and Marginal Economic Benefit Through Dairy–Cropland Recoupling: A Case Study of a Large-Scaled Dairy Farm

Agriculture
The decoupling of dairy production from cropland can increase environmental burdens and constrain the recycling of nutrients in manure in land-limited, purchased-feed-dependent large-scaled dairy farms. This study evaluated the environmental and marginal

Follicle Stimulating Hormone in Cattle Breeding: Fundamentals, Innovations, and Scope

Animal Research and One Health, EarlyView.
FSH is crucial in cattle reproduction, with exogenous administration enhancing breeding and embryo production. Recombinant FSH offers advantages over pituitary‐extracted variants, including fewer injections, reduced stress, and safer production. These innovations improve breeding efficiency, optimize reproductive outcomes, and contribute to sustainable

MicroRNA‐microbiota interactions: Emerging strategies for modulating intestinal homeostasis and enhancing host health

iMetaOmics
Long‐term artificial selection and environmental shifts have driven adaptive changes in both the host genome and the intestinal microbiota. The complex symbiotic relationship between these two has become essential for maintaining intestinal homeostasis ...

Effects of Dietary Forage Proportion on Feed Intake, Growth Performance, Nutrient Digestibility, and Enteric Methane Emissions of Holstein Heifers at Various Growth Stages

Animals, 2019
Enteric methane (CH4) emissions from young ruminants contribute to a substantial proportion of atmospheric CH4 accumulation. Development of emission inventory and mitigation approaches needs accurate estimation of individual emission from animals under ...

Northern bobwhites associated with native grass and shrubs have improved survival

The Journal of Wildlife Management, EarlyView.
Survival rates of adult northern bobwhites were improved by a combination of grazed native warm‐season grasses and well‐interspersed shrubs. Our study suggests that incorporating native warm‐season grass cattle forages into existing operations across the southeastern United States may be a viable working‐lands conservation strategy to create habitat ...

Disorders of acid-base balance promote rumen lipopolysaccharide biosynthesis in dairy cows by modulating the microbiome

Frontiers in Microbiology
IntroductionDisorders of acid-base balance in the rumen of dairy cows have a significant impact on their health and performance. However, the effect of transient differences in pH on susceptibility to subacute ruminal acidosis (SARA) and ...
