Comparative analysis of microRNAs in bovine colostrum and neonatal calf blood
Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND MicroRNAs (miRNAs) are short non‐coding RNAs that participate in a wide range of biological processes. MiRNAs are present in high concentrations in colostrum, and these may be potentially transferred to newborn calves being fed colostrum.

Milk production and survival of spring-calving carryover cows in New Zealand dairy herds : a thesis presented in partial fulfilment of the requirements for the degree of Master of Science in Animal Science at Massey University, Manawatu, New Zealand [PDF]
, 2017 Non-pregnant cows are generally culled from dairy herds and replaced with two-year-old heifers. Alternatively, non-pregnant cows can be dried-off at the end of lactation, retained for one year (carried over), before being mated and returned to a milking ...

Journal of the Science of Food and Agriculture, EarlyView.Abstract BACKGROUND This study created functional fermented goat milk by adding blackberry pulp and probiotics (Lactobacillus acidophilus LA‐5 and Bifidobacterium animalis subsp. lactis Bb‐12). The preparation involved two variations of fermented goat milk with blackberry (Rubus sp.), distinguished by the absence (fermented goat milk, FGM) or inclusion

Validation of Body Condition Scores with Ultrasound Measurements of Subcutaneous Fat of Dairy Cows
Journal of Dairy Science, 1995 This research validated body condition scores with ultrasound measurements of subcutaneous fat. Fifty Holstein cows were evaluated during three sessions in 1993. Cows scored during each session were divided into three groups of 15 or 20 cows. Body condition scores were assigned by one trained individual, utilizing a five-point (1 = thin to 5 = fat ...

Evaluation of on-farm labour saving strategies for optimisation of herd size that could be managed by one operator [PDF]
, 2009 End of project reportAlternative milking frequencies Once a day (OAD) milking throughout lactation of a herd (over 2 years, incorporating 24% heifers) resulted in loss in milk solids (MS) production of 17% per cow.

Density‐dependent habitat selection in plains bison
The Journal of Wildlife Management, EarlyView.Using GPS collar data, we tested whether habitat selection of plains bison in Grasslands National Park, Canada, was density dependent. Bison selected for areas of high vegetation productivity far from human activity when population density was low and increased use of lower productivity habitat closer to disturbance as density increased.

Developing selection indexes & estimation of genetic parameters for traits of economic importance in dairy cattle under once-a-day milking : a thesis presented in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Animal Science, Institute of Veterinary, Animal Biomedical Sciences, Massey University, Palmerston North, New Zealand [PDF]
, 2016 In New Zealand, about 5% of dairy herds are milked once-a-day (OAD). The cows are inseminated using sires from the twice-a-day milking system (TAD) evaluated on breeding worth (BW) or an OAD selection index.

A simple index for assessing cumulative human impacts on mountain lakes
Limnology and Oceanography: Methods, EarlyView.Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped
