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...

Traditionally, milk fever prevention programs have attempted to directly alter Ca status of dairy cows at calving. Common approaches include feeding pre-fresh dairy cows diets containing anionic salts, restricting dietary Ca, feeding hyper-dietary Ca and administering Ca boluses. There is an abundance of research in regard to the mechanisms associated with dietary Ca alteration, dietary cation-anion difference as related to parathyroid hormone and vitamin D and the role they play in the...

Canada is one of the largest pork and beef exporters in the world. The volume and value of Canadian meat exports have increased to ~$9 billion/year, and the export markets have expanded significantly from the traditional buyers. However, the meat export landscape has evolved during the last years, becoming more competitive, with major players trying to access the same import markets. Quality assurance and meat differentiation based on quality attributes contribute to meeting domestic and...

Low protein diets have improved nitrogen (N) utilization, but dietary N for the endogenous synthesis of non-essential amino acids (NEAA) may be limiting. Inclusion of a non-protein nitrogen (NPN) may improve utilization of essential amino acids (EAA). A N-balance study was conducted, where 90 growing barrows were assigned to 1 of 10 dietary treatments. Diets contained no ammonium phosphate (NAP; EAA-N:TN of 0.56) or were supplemented with 1.7% ammonium phosphate (AP; EAA-N:TN of 0.50) with...

Despite environmental and public health (bacterial resistance) issues, supranutritional levels of zinc oxide (ZnO) are still commonly used to prevent diarrhea in post-weaning piglets. In Canada, these levels represent more than eight-fold the CFIA proposed maximum levels at 300 mg/kg. The limited knowledge of their consequences for the metabolism of trace minerals has hampered the replacement of this strategy without compromising piglet health. Our laboratory has performed a series of...

Canada’s broiler chicken industry has taken great steps to reduce the use of antibiotics in production. Chicken Farmers of Canada successfully implemented a plan to remove both Category I and II antibiotics for preventive use from broiler feeds. There may be benefits from similar products for birds raised for egg production. Our research team has been involved in the evaluation of feed ingredients of marine origin. Seaweeds available off the Atlantic Coast of Canada were incorporated...

I. INTRODUCTION Exogenous enzymes are susceptible to denature when exposed to low-pH conditions, normally prevailing in the gastric phase. Hence, resistance to low-pH is considered one of the key criterion for the suitability of commercial phytase enzymes for animal feed application. The pH-stability is assessed in-vitro by measuring the recovery of enzyme activity after exposing enzyme protein to low-pH buffers. To mimic gizzard conditions, pH 2.5-3.5 with added pepsin is often...

I. INTRODUCTION The continuous genetic improvements are increasing the first commercial egg size produced and extending the production life of the layer hens worldwide. These improvements are related to what happens at rearing and at the start of the production. Early studies showed that while approximately 60 to 75% of the calcium destined for the shell comes directly from intestinal absorption (Driggers and Comar, 1949), up to 36% could be traced to bones (Mueller et al., 1964)....

Enzymes have shown promising effects on performance and intestinal health in broilers (Toghyani et al., 2022). However, the dosage effect of enzymes and combination of different enzymes have not been extensively evaluated under the coccidial vaccine challenge condition. Therefore, a feeding study was conducted to examine the effect of dosage of xylanase+glucanase and the effect of its combination with a high level of phytase on growth performance, health, and welfare of broilers under a mild...

Zinc is an essential trace mineral in broiler nutrition. However, in commercial practice it is often fed above requirements to prevent any deficiencies. To prevent deficiencies, Zinc hydroxychloride (HTM) (IntelliBond®, Trouw Nutrition, Netherlands) provides versatility to optimise the producer’s trace mineral program and allow them to feed levels lower than those commercially used today in the form of sulfate trace minerals (STM). Raw data of nine studies was combined into...

Introduction: Previous studies have led to observations regarding the negative impact of non-starch polysaccharides in corn-soybean meal diets on nutrient digestibility. Therefore, steps are undertaken to positively influence nutrition in livestock by utilizing enzymes. This experiment was conducted to evaluate the effects of ethyl-enzyme liquid energy (ELE) on growth performance, nutrient digestibility, meat quality traits and carcass grades of grower-finisher...

Mike Persia (Virginia Tech) Experiments were conducted to determine the bioavailability of fine ground aragonite (FGA) using 0-14 d old broilers and to determine the use of FGA on performance, eggshell quality, and tibia ash (TA) of laying hens from 28-56 wks. In experiment 1, 450 as hatched Ross 708 broilers were fed a basal diet without either LS or FGA containing 0.35% Ca and LS and FGA additions resulting in 0.43, 0.51, 0.59, and 0.67% Ca. Body...
