Interpretive Summary: Development of a dynamic model for prediction of energy in milk protein, lactose, fat, and enteric methane emissions in goats based on energy balance and indirect calorimetry studies
The present model using mixed diets with different by-products to obtain macronutrient balance, methane emission, and milk performance during mid lactation could be an interesting tool to help farmers, without the costs of running animal experiments.

Interpretive Summary: Modeling net energy partition patterns of growing–finishing pigs using nonlinear regression and artificial neural networks
Net energy (NE) is the most refined energy system in animal nutrition, and understanding the NE partition patterns of pigs can help us to develop suitable feeding strategies to improve the growth performance and carcass traits of pigs. However, it is time-consuming, laborious, and expensive to directly measure the NE; thus, establishing a predicted model is more efficient.

Interpretive Summary: Impact of ileal indigestible protein on fecal nitrogen excretion and fecal microbiota may be greater compared with total protein concentration of diets in growing pigs
Dietary protein concentration has been gradually reduced because reductions in protein concentration in swine diets are known to be beneficial in terms of feed costs, nitrogen excretion, and intestinal microbiota. However, ileal indigestible protein concentration may be more influential in those variables of pigs compared with total protein concentration in diets because ileal indigestible protein considers both protein concentration and digestibility of diets.

Interpretive Summary: Productive and physiological responses of feedlot cattle receiving different sources of Ca salts of fatty acids in the finishing diet
Supplemental fat has been provided to feedlot cattle to increase energy density of their diets, and may yield nutraceutical advantages if includes polyunsaturated fatty acids (FA). Alternatively, carcass quality can be improved when the fat supplement is based on saturated and monounsaturated FA.

Interpretive Summary: Evaluation of carinata meal or cottonseed meal as protein sources in silage-based diets on behavior, nutrient digestibility, and performance in backgrounding beef heifers
Increased atmospheric CO2, rising temperatures, and altered patterns of precipitation can limit the production of certain crops commonly used in agriculture, increasing risk, cost, and availability of feedstuffs. The search for alternative plants that could thrive in these changing scenarios is necessary to provide producers with a broader array of options to feed cattle.

Interpretive Summary: Changes in milk fat globule physical properties and milk fatty acid composition throughout the lactation cycle of Laoshan goat
The composition and physical properties of milk fat affect the quality and sensory properties of dairy products. However, changes in the physical properties of milk fat globules (MFGs) and profiles of milk fatty acids (FAs) of goat milk throughout the lactation period remain unclear.

Interpretive Summary: Effect of a biosynthetic bacterial 6-phytase on the digestibility of phosphorus and phytate in midlactating dairy cows
Traditionally, it has been believed that dairy cows are able to fully utilize the phosphorus (P) in feed, including that from plant-derived phytate, because of phytase activity of bacteria in the rumen. However, recent data have shown otherwise.

Interpretive Summary: Red clover supplementation modifies rumen fermentation and promotes feed efficiency in ram lambs
Red clover is rich in the bioactive isoflavone, biochanin A. The goal was to evaluate the impacts of biochanin A supplementation via red clover hay on growth performance of ram lambs as well as the rumen microbiota and fermentation.

Interpretive Summary: Identification of potential candidate genes and regulatory pathways related to reproductive capacity in hypothalamus and pituitarium of male ducks (Anas platyrhynchos) by differential transcriptome analysis
Individual reproductive capacity is crucial to poultry breeding and reproduction. The hypothalamus–pituitarium–gonad axis is an important pathway regulating animal spermatogenesis and sexual behavior. This study identified the neuroactive ligand–receptor interaction pathway as the potential biological pathway regulating the semen quality and sexual behavior by differential transcriptome analysis of the hypothalamus and pituitarium of male ducks.

Interpretive Summary: Cryoprotectant effects of natural honey on spermatozoa quality of pre-freezing and frozen-thawed boar semen
To preserve the semen of male pigs for long-term usage, especially for artificial insemination, semen samples are frozen at temperatures below zero degrees. This research study was conducted with the aim of improving the qualities of semen samples from male pigs that are usually negatively impacted by extremely low temperatures during the preservation process using liquid nitrogen.

Interpretive Summary: Apparent jejunal amino acid digestibility, gut morphology, and the expression of intestinal amino acid transporters in pigs fed protein or free amino acids
The amino acids (AA) in the diet of pigs are usually supplied as a mix of proteins and free AA. Proteins need to be digested first before their constituent AA become available to the animal. Free AA, together with small peptides, are readily available without the need for digestion.

Interpretive Summary: Serum metabolomic characterization in pigs in relation to birth weight category and neonatal nutrition
The objective of this study was to characterize developmental differences in low birth weight (LBW) and normal birth weight (NBW) piglets with or without pre-weaning nutrient restriction using serum metabolomic profile analysis. Through the serum metabolite analysis, at weaning, we saw fewer metabolites associated with fatty acid oxidation, and glycolysis in the LBW pigs compared to the NBW.

Interpretive Summary: Characterization of sow milk N-linked glycoproteome over the course of lactation
Milk is essential for healthy growth and development of neonates, with proteins in milk serving as key nutrients and regulators of these processes. Protein activity is affected by modifications made to their structure including the addition of sugar groups called glycans. Here we present the characterization of sow milk proteins modification with glycan groups on asparagine and glutamine amino acids in colostrum, transitional, and mature milk of pigs.

Chicken industry calls for action regarding egg prices
The National Chicken Council (NCC) has called for the United States Food and Drug Administration (FDA) to take measures to decrease egg prices. The chicken industry is examining a policy that forces the broiler industry to destroy safe eggs, due to the current outbreak of highly pathogenic avian influenza (HPAI) in the United States.
