Summary
Replacing soybean meal (SBM) with hazelnut kernel oil meal (HKM) in broiler diets negatively impacts growth performance and carcass yield. Even 50% substitution with HKM is not recommended for commercial broiler diets.
Area of Science:
- Animal Science
- Poultry Nutrition
- Feed Science
Background:
- Soybean meal (SBM) is a primary protein source in broiler diets.
- Hazelnut kernel oil meal (HKM) is a potential alternative protein ingredient.
Purpose of the Study:
- To evaluate the effects of substituting soybean meal (SBM) with hazelnut kernel oil meal (HKM) in broiler diets.
- To determine the optimal level of HKM inclusion for broiler growth and carcass characteristics.
Main Methods:
- A six-week feeding trial with 450 one-day-old Ross 308 broiler chicks.
- Three dietary treatments: control SBM, 50% HKM substitution, and 100% HKM substitution.
- Evaluation of body weight gain, feed intake, feed conversion ratio, carcass yield, abdominal fat, and organ weights.
Main Results:
- Broiler growth performance (weight gain, feed intake, feed conversion ratio) was negatively affected by HKM inclusion (P < 0.05).
- Carcass yield and abdominal fat pad weights were significantly reduced in broilers fed HKM diets compared to SBM (P < 0.05).
- Edible inner organ weight was highest in broilers fed HKM diets (P < 0.05).
Conclusions:
- Soybean meal (SBM) cannot be replaced by hazelnut kernel oil meal (HKM) even at a 50% level in commercial broiler diets.
- HKM inclusion negatively impacts key growth and carcass parameters in broilers.
- Further research may be needed to explore potential benefits or modifications for HKM utilization in poultry feed.

01:28Proteins: Dietary Sources and Requirements
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...
01:18Lipids: Dietary Sources and Requirements
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 meats, shellfish,...
02:35Key Elements for Plant Nutrition
Like all living organisms, plants require organic and inorganic nutrients to survive, reproduce, grow and maintain homeostasis. To identify nutrients that are essential for plant functioning, researchers have leveraged a technique called hydroponics. In hydroponic culture systems, plants are grown—without soil—in water-based solutions containing nutrients. At least 17 nutrients have been identified as essential elements required by plants. Plants acquire these elements from the atmosphere, the...
