I. INTRODUCTION Poultry meat is the second-largest meat source with excellent quality of proteins and essential micronutrients for human nutrition globally (Pawar et al., 2016). However, the pursuit of increased meat yield, lean mass ratio and large breast muscle has had significant impacts on meat quality in broilers. Moreover, in modern commercial broiler rearing systems, high stocking density and various stress factors also inevitably lead to impaired growth performance and meat...

Tri-butyrin is regarded as an ideal molecule to supply both butyrate and mono-butyrin to the small intestine (SI) to maintain intestinal function, modulate the immune response and improve broiler growth performance (Moquet et al., 2016; Moquet et al., 2018). Valerins have been shown to positively affect the morphology of the SI mucosa and reduce the incidence of necrotic enteritis (Onrust et al., 2018). To date, little information is available as to the extent to which valerin and butyrin in...

I. INTRODUCTION Soybean meal (SBM) is the most important plant protein source in broiler diets. Although most of the proteins in SBM are highly digestible, some proteins including glycinin, protease inhibitors, and antigenic proteins are indigestible and can cause intestinal damage and impair immune functions resulting in sub-optimal growth performance (Pan et al., 2016). The supplementation of SBM with appropriate commercially available proteases provides a potential strategy to...

Introduction In developing countries, the poultry industry is experiencing some critical issues with animal feed prices, which are unpredictable in the current scenario, as raw ingredients, primarily corn and soybean, have been increasing in price day by day (Alagawany and Attia 2015). As a result, there is a need to consider some low-cost resources, such as agricultural by-products and other crops, which are significantly less expensive than conventional feed stuff. As a result,...

Introduction Creatine (essential for energy metabolism) and glutathione (GSH; an important non-enzymatic antioxidant) are major metabolites of glycine [the simplest amino acid (AA)] in animals (Fig. 1). Specifically, arginine:glycine amidinotransferase (AGAT) and guanidinoacetate N-methyltransferase (GAMT) convert glycine into creatine in the presence of arginine and methionine, whereas γ-glutamylcysteine synthetase and glutathione synthetase catalyze the formation of GSH...

4.1 Introduction The metabolism of most nutrients in domestic dogs and cats is similar to that in other mammals (Baker and Czarnecki-Maulden 1991). Thus, the qualitative dietary requirements of dogs and cats for most nutrients [e.g., amino acids (AAs) that are not formed de novo in animal cells] are similar to those for omnivores (e.g., humans and pigs). However, dogs and cats have a relatively short digestive tract (He et al. 2024) and have evolved to have some unique feeding...

1. Introduction Increased atmospheric emissions of greenhouse gases (GHGs), such as nitrous oxide (N 2 O), carbon dioxide (CO 2 ), and methane (CH 4 ), are the primary cause of climate change. These emissions result in unpredictable and erratic rainfall, floods, and droughts [1]. In 2020, agriculture contributed 5865.47 MtCO 2 e, representing 12.34% of its total emissions (47,513.15 MtCO 2 e), including land-use change and forestry...

Additives are part of the strategies for adding value to food, and their interest, in the current context of raw material prices, is even more evident. Nevertheless, there is a tendency to simplify their action to stick to the primary logic of their nature and easily generate an economic advantage. In doing so, we are likely to limit ourselves by failing to fully consider the scope of their work. In the case of the increasingly popular proteases, this involves a "simple" recovery of the...

Insect farming is water-efficient and reduces food waste while producing quality protein, making it a potential solution to food sustainability and food security issues. Black soldier fly larvae, as an excellent source of protein, calcium, and a bacteria-fermentable polysaccharide called chitin, is a promising poultry feed ingredient. A 20-week feeding trial was conducted to evaluate the effects of dietary inclusion of black soldier fly larvae meal (BSFM) on the gut microbiota and SCFA...

Rendering involves repurposing animal co-products that would otherwise be discarded. It converts the parts of a meat animal we choose not to eat into stable, usable materials such as fuel, pet food, and livestock feed, creating a highly sustainable alternative. Below, learn more about products made from rendered materials in detail. You can discover...

This study aimed to evaluate the effects of four dietary lipid supplements on milk composition and butter properties. Ten multiparous Holstein cows (64±21 days in milk) were used in a replicated 5×5 Latin square design. Cows received a basal diet without supplementation (CTL) or with 2% (dry matter basis) fatty acids (FA) provided as soybean oil (SO), calcium salts of palm FA (CS), hydrogenated tallow FA (HT) or palmitic acid-enriched supplement (PA). Treatment periods lasted 21...

Butyric acid is a short-chain fatty acid (SCFA) that is produced naturally by fermentation of fiber in the lower gastrointestinal tract (GI). Butyric acid has known benefits such as providing energy to colonocytes, intestinal barrier function, apoptosis regulation, control cytokine production, mucus synthesis, and intestinal cell proliferation, differentiation and maturation. Exogenous supplementation of butyric acid was initially developed by making a salt derivative, with either sodium or...

Functional foods can be defined as foods containing bioactives that provide health benefits beyond basic nutrition. Substantial research has examined phytochemical bioactives; however, there is also interest in bioactives from animals. Functional foods of animal origin are due to the bioactives present in foods such as eggs, dairy, meat and fish. This presentation will introduce and overview the concept of functional foods and outline the uniqueness of animals as a source of bioactives for...

10 years of data from 168 primary crop products and 44 primary animal products from 240 countries summarized in a Bayesian learning network highlights that ruminant meat and milk are primary drivers of agricultural greenhouse gas emissions in food production systems globally. However, these same products, along with eggs and non-ruminant meat, are also linked positively to nearly every nutrient essential for human life, such that, irrespective of agricultural system studied, targeting...
