Summary
Beef tallow can be effectively used in growing-finishing pig diets. Adding an emulsifier can compensate for reduced energy density, maintaining performance and economic viability.
Area of Science:
- Animal Nutrition
- Swine Production
- Feed Science
Background:
- Dietary fat sources significantly impact pig performance.
- Beef tallow offers a high energy value for animal feed.
- Optimizing energy density and ingredient utilization is crucial for cost-effective swine production.
Purpose of the Study:
- To evaluate the effects of beef tallow inclusion in growing-finishing pig diets.
- To assess the impact of an emulsifier on pig performance with reduced energy diets.
- To determine the economic viability of using beef tallow with and without emulsifiers.
Main Methods:
- Two trials were conducted involving growing-finishing barrows.
- Diets varied in beef tallow inclusion (5% and 10%) and metabolizable energy (ME) levels.
- An emulsifier was included in specific low-ME diets to evaluate its effect.
Main Results:
- Feed conversion worsened in pigs fed beef tallow diets with lower ME (3080 and 2930 kcal ME/kg) without emulsifier.
- The addition of 0.1% emulsifier in a 2930 kcal ME/kg diet improved performance.
- Pigs fed beef tallow at 3230 kcal ME/kg or a reduced energy diet (3080 kcal ME/kg) with emulsifier showed comparable economic availability to those fed soybean oil.
Conclusions:
- Beef tallow is a viable energy source for growing-finishing pigs.
- Emulsifiers can effectively compensate for reduced dietary energy density from beef tallow.
- Strategic use of beef tallow and emulsifiers can lead to cost-effective swine diets.
