Interpretive Summary: Physiological response of weaned piglets to two transport durations observed in a Canadian commercial setting
Multi-site pig production is a standard industry practice, though it risks stressing animals during transportation. Most data involving transportation effects was done in market hogs, and the current Canadian transport regulations weigh heavily on these studies' information.

Interpretive Summary: Smith Nutrient Restriction followed by Realimentation sheep
Nutrient restriction in pregnant females has been repeatedly shown to have adverse effects on the growth and development of their offspring. Realimentation following nutrient restriction may be a strategy to mitigate the negative growth effects that maternal nutrient restriction has on offspring.

Interpretive Summary: Repeatability of gaseous measurements across consecutive days in sheep using portable accumulation chambers
Global temperatures are expected to increase over the next thirty years; the implications of climate change will have a large impact on livestock population and production, which will affect food security. Ruminant animals have contributed to 39.8% of global agricultural greenhouse gas emissions, but will play a role in the mitigation of greenhouse gas emissions through the development of sustainable livestock production and the adoption of mitigation measures.

Interpretive Summary: Myostatin suppresses adipogenic differentiation and lipid accumulation by activating crosstalk between ERK1/2 and PKA signaling pathways in porcine subcutaneous preadipocytes
A study recently published in the Journal of Animal Science aimed to determine the effect of myostatin on lipid accumulation in porcine subcutaneous preadipocytes and to further explore the potential molecular mechanisms.

Interpretive Summary: The effect of vitamin C on long-haul transport stress in beef steer calves
Long-haul transport may occur at several points during the lifespan of feedlot cattle and is a source of undesirable stress on the wellbeing of these animals. Performance can subsequently suffer and lead to reduced health and productivity.

Interpretive Summary: Effect of bone morphogenetic protein 4, gremlin, and connective tissue growth factor on estradiol and progesterone production by bovine granulosa cells
It has been well documented that Bone morphogenic proteins (BMPs) participate in the paracrine regulation of granulosa cell function in multiple species. However, it is unknown if responses to BMPs change with follicular size or interacts with connective tissue growth factor (CTGF) or BMP antagonists (e.g., gremlin) to directly affect granulosa cell function in cattle.

Interpretive Summary: Feeding graded inclusion levels of raw and cooked garbanzo beans to cats
Garbanzo beans (Cicer arietinum) are a popular and important legume food protein crop in human nutrition but is not as well utilized or studied in companion animal nutrition. Because raw garbanzo beans contain anti-nutritional factors, it may potentially have negative impacts on digestibility, fecal characteristics, or the gut health of companion animals.

Interpretive Summary: Fonesca appeasing substance bos indicus summary
Transport and feedlot entry are among the most stressful events in the lives of feedlot cattle, and the stress from these events tend to adversely impact welfare and productivity. Therefore, there is a great interest in strategies to relieve these stresses to improve welfare and performance.

Interpretive Summary: Effects of bismuth subsalicylate and encapsulated calcium-ammonium nitrate on feedlot beef cattle production
Sulfur is an important element for the ruminant animal due to its role in bacterial growth and metabolism, but high concentrations of dietary sulfur can be related to reductions in growth performance and the incidence of polioencephalomalacia.

Interpretive Summary: Effect of divergence in residual methane emissions on feed intake and efficiency, growth and carcass performance, and indices of rumen fermentation and methane emissions in finishing beef cattle
Global food production has benefitted from the ability of ruminant livestock to convert plant matter into high-quality sources or dairy and meat protein for human consumption, but ruminant derived food products have a much greater carbon intensity. Therefore, mitigation strategies to reduce enteric methane emissions from cattle have been a key research priority for livestock scientists in recent decades.

Interpretive Summary: Effects of roughage type on particle separation, rumination, fiber mat characteristics, in situ degradation, and ruminal fermentation parameters in beef steers
Physically effective neutral detergent fiber (peNDF) is essential for maintaining the rumen epithelial lining and can be estimated based on the diet's particle size and NDF concentration. Roughages have unique physical characteristics that contribute to the density of the ruminal mat and influence ingredient digestibility, retention times, and particle degradation.

Interpretive Summary: Estimation of genetic parameters for superovulatory response traits in Japanese Black cows
Japanese Wagyu cattle are one of Japan's greatest treasures and are famous for their excellent meat quality. In Japan, embryo transfer is widely used, and the value of Japanese Black calves is much higher than that of the other beef breeds.

Interpretive Summary: Increasing dietary proportion of heat grain in finishing diets containing distillers’ grains: impact on nitrogen utilization, ruminal pH, and digestive function
The use of Dried distillers’ grains with solubles (DDGS) in ruminant diets has increased drastically over the last ten years. This alternative feed resource offers a product that is very high in crude protein (CP).

Interpretive Summary: Short term health impacts of feeding cats black soldier fly larvae meal
There is currently great potential for including black soldier fly larvae meal (BSFLM, Hermetia illucens) in companion animal feed. Although high in protein and nutrient rich, the health impacts of including BSFLM in companion animal feed are largely unknown.

Interpretive Summary: Herbage mass and allowance and animal genotype affect daily herbage intake, productivity, and efficiency of beef cows grazing native subtropical grassland
It is crucial that beef cow-calf systems in subtropical native grasslands, such as Campos, must improve their cow-calf and economic productivity without external inputs while still reducing the environmental impact. This could potentially be done through the control of herbage allowance, improving herbage production, cow herbage intake, and biological efficiency.

Interpretive Summary: Influences on the assessment of resource- and animal-based welfare indicators in unweaned dairy calves for usage by farmers
A study recently published in the Journal of Animal Science aimed to apply possible animal welfare indicators for unweaned dairy calves on conventional dairy farms with early cow-calf separation. An animal welfare assessment, using 7 resource-based and 14 animal-based indicators, was conducted at 42 typical Western German dairy farms (844 calves) in 2018 and 2019 by two observers.

Interpretive Summary: Impacts of water quality on feed and water intake of cattle
Water quality can be problematic in the livestock industry due to reduced fresh water and groundwater supplies. Most water consumed by livestock tends to be saline or brackish however the effects water quality might have on overall health, feed intake and digestibility are unknown.

Interpretive Summary: Dietary zinc concentration and lipopolysaccharide injection affect circulating trace minerals, acute phase protein response, and behavior as evaluated by an ear-tag–based accelerometer in beef steers
The National Animal Health Monitoring System estimates that bovine respiratory disease affects 21.2% of all beef cattle placed in feedlots. Bovine respiratory disease often affects cattle during the receiving period, which can involve many stressors; identifying morbid cattle early may lead to improved animal welfare through decreased morbidity and mortality and increased treatment efficacy.
