Summary
Diet composition significantly impacts poultry odor emissions. Feeding canola seed increased methyl mercaptan, while soybean meal diets led to higher methyl mercaptan and total sulfur emissions in meat chickens.
Area of Science:
- Animal Science
- Environmental Science
- Agricultural Science
Background:
- Odour abatement is crucial in the poultry industry.
- Dietary components can influence the generation of malodorous compounds.
- Understanding these links is vital for sustainable poultry production.
Purpose of the Study:
- To investigate the relationship between diet and odour emissions in meat chickens.
- To identify specific dietary ingredients affecting the emission of volatile organic compounds.
Main Methods:
- Two experiments were conducted with Ross 308 male meat chickens.
- Diets varied in ingredients like canola seed, canola meal, and meat meal.
- Odour emissions were quantified using Fourier transform infrared (FTIR) spectroscopy.
Main Results:
- Canola seed inclusion increased methyl mercaptan and decreased diacetyl emissions.
- Soybean meal-based diets resulted in higher methyl mercaptan and total sulfur emissions.
- Specific odorous compounds identified include methyl mercaptan, diacetyl, and sulfur compounds.
Conclusions:
- Diet composition directly influences odour emissions from meat chickens.
- Ingredient selection, particularly sulfur-rich components, plays a key role in odour profiles.
- Findings provide insights for formulating poultry diets to mitigate odour pollution.

02:39Emission Spectra
76.5K
When solids, liquids, or condensed gases are heated sufficiently, they radiate some of the excess energy as light. Photons produced in this manner have a range of energies, and thereby produce a continuous spectrum in which an unbroken series of wavelengths is present.

In biological systems, most metabolic pathways are interconnected. The cellular respiration processes that convert glucose to ATP—such as glycolysis, pyruvate oxidation, and the citric acid cycle—tie into those that break down other organic compounds. As a result, various foods—from apples to cheese to guacamole—end up as ATP. In addition to carbohydrates, food also contains proteins and lipids—such as cholesterol and fats. All of these organic compounds are used...

Matter: Pure Substances and Mixtures
According to its composition, the matter can be classified into two broad categories — pure substances and mixtures.
A pure substance is a form of matter that has a constant composition throughout with uniform properties. For example, any sample of sucrose has the same composition and same physical properties, such as melting point, color, and sweetness, regardless of the source from which it is isolated.

1.8K
Consuming animal-based products offers high-quality proteins that contain optimal levels and combinations of essential amino acids, crucial for tissue repair and growth. Foods like eggs, milk, fish, and most meats are a source of complete proteins. Legumes and cereals are abundant in proteins; however, they typically lack a full range of essential amino acids. As a result, they are considered incomplete protein sources. Some plant sources like soybeans, quinoa, and amaranth do contain complete...

Carbohydrates are predominantly obtained from plant sources. With the exception of lactose found in milk and insignificant glycogen amounts in meat, most consumed carbohydrates have plant origins. Monosaccharides and disaccharides, or sugars, can be sourced from fruits, honey, milk, sugar cane, and sugar beets. Grains and vegetables are rich in the polysaccharide starch. Two types of polysaccharides provide fiber: cellulose, which is abundant in many vegetables, forms undigestible roughage or...

Lipids are an essential component of a balanced human diet. Triglycerides, which make up the majority of dietary lipids, are found in both saturated fats—commonly present in meat, dairy products, and certain tropical plants like coconut, and hydrogenated oils such as margarine and baking shortenings (trans fats)—and unsaturated fats, which are abundant in seeds, nuts, olive oil, and most vegetable oils. The main sources of cholesterol include egg yolks, various meats and organ...
