Statistical Methods Revisited for Estimating Daily Milk Yields: How Well do They Work?

Frontiers in Genetics, 2022
Cost-effective milking plans have been adapted to supplement the standard supervised twice-daily monthly testing scheme since the 1960s. Various methods have been proposed to estimate daily milk yields (DMY), focusing on yield correction factors.

Descriptive, comparative, and functional anatomy of the facial musculature in cattle (Bos taurus)

The Anatomical Record, EarlyView.
Abstract Facial expressions can provide insight into animal emotions and pain, but no standardized system for assessing the entire facial display in cattle (Bos taurus Linnaeus) exists. The Facial Action Coding System (FACS), originally developed for humans, identifies distinct facial movements based on mimetic muscles.

Dietary Mannan‐Rich Fractions Attenuate Weaning Stress in Piglets via Modulating Gut Microbiota and TLR5/NF‐κB Signaling

Animal Research and One Health, EarlyView.
This study aimed to investigate the potential of a mannan‐rich fraction (MRF) as a dietary intervention to alleviate weaning stress in piglets. Our results revealed that MRF could alleviate weaning stress by modulating the gut microbiota and the TLR5/NF‐κB signaling pathway, offering a novel and sustainable alternative to antibiotic use in swine ...

Energy Metabolism of Dairy Cattle

Journal of Dairy Science, 1981
Energy metabolism research during the past 25 yr has resolved many uncertainties of energy use by lactating cows. Use of metabolizable energy for milk production essentially is unaffected by milk yield but is slightly influenced by its source. Estimates of efficiency of use for milk production (60 to 64%) are lower than earlier estimates (69 to 70 ...

Comparative Meta‐Analysis of Antimicrobial Peptides in Aquatic and Terrestrial Livestock Species

Animal Research and One Health, EarlyView.
A global meta‐analysis of 58 studies (926 effect sizes and 29 species across five taxa) revealed that dietary antimicrobial peptides generally improve growth performance, blood metabolites, and immune responses. The greatest benefits were observed in omnivorous livestock, such as pigs and chickens. Dose‐duration effects were evident. An optimal outcome

Physiological Responses, Growth Rate and Blood Metabolites Under Feed Restriction and Thermal Exposure in Kids [PDF]

Journal of Stress Physiology & Biochemistry, 2014
The study was carried out to study the cumulative effect of thermal stress and feed restriction in kids. Twelve kids of Alpine x Beetle cross were divided into two groups. Group 1 served as control and group 2 was put on restricted feeding and exposed at

Soil Ingestion by Dairy Cattle

Journal of Dairy Science, 1982
Sets of 5 to 10 random fecal samples were obtained from animals of various management groups of nine dairy herds. Titanium content of feces and soils to which the animals had access was determined by x-ray fluorescence spectroscopy. Titanium of feces was the indicator of soil ingestion, which was calculated for 60% digestibility of the total ration dry

Co‐Infection of Brucella canis and Brucella melitensis in a Domestic Dog With Zoonotic Transmission to Human, China

Animal Research and One Health, EarlyView.
Source attribution figure for human and dogs Brucella canis infections. ABSTRACT We report a rare occurrence of genetic material from both Brucella canis and B. melitensis detected in a domesticated dog from Jiangsu Province, China. The detection was confirmed through serological assays, quantitative PCR (qPCR), metagenomic and genomic sequencing ...

External Parasites of Dairy Cattle

Journal of Dairy Science, 1982
Insects such as stable flies, house flies, horn flies, face flies, mosquitoes, horse flies, deer flies, cattle grubs, and lice as well as ticks and mites are the major external parasites of dairy animals in the United States. These pests cause obvious discomfort to livestock and economic effects of heavy populations usually are discerned easily ...
