Research report: Effect of adding tribasic copper chloride (TBCC) to diets for weanling pigs

Copper is an essential micronutrient for animals. It is involved in cellular respiration and connective tissue development as well as being an essential component of several enzymes. High doses of copper—about 20 times the nutritional requirement—have been shown to improve growth performance in pigs. This may be because copper has an antimicrobial effect in the intestinal tract.

When supplemental copper is added to pig diets, it is usually in the form of copper sulfate. However, another form called tribasic copper chloride (TBCC) has been shown to be equally effective and may be  more bioavailable, but it is not yet known how much TBCC should be fed to optimize performance. Therefore, an experiment was conducted to determine the effects of adding 100 or 200 mg/kg TBCC to diets fed to weanling pigs.

Podcast: Requirements for digestible calcium by 100 to 130 kg pigs

Dr. Laura Merriman, a recent Ph. D. recipient from the Stein Monogastric Nutrition Lab, discusses the results of her research into the requirement for digestible calcium in 100 to 130 kg finishing pigs. Adapted from a presentation at the 2016 ASDA-ASAS-CSAS-WSASAS Joint Annual Meeting, Salt Lake City, Utah, July 19-23.

Press release: Research at Illinois studies importance of threonine:lysine ratio in pig diets

URBANA, Ill. – To optimize performance in growing pigs, it is important to feed not only enough protein, but the right balance of amino acids. Research from the University of Illinois is helping to determine the correct ratio of threonine to lysine in pig diets, and how this ratio is affected by the fiber content of the diets.

Hans H. Stein, professor of animal sciences at Illinois, explains that because producers are increasingly feeding lower-cost, high-fiber coproducts, it's important to understand how dietary fiber affects pigs' nutritional needs.

Press release: U of I co-hosts summit on benefits of precision nutrition

URBANA, Ill. – The 3rd International Phytate Summit (IPS3), held in November and hosted by the University of Illinois, the University of Arkansas and AB Vista, brought together top scientists and nutritionists from 22 countries to discuss the benefits of precision nutrition—and in particular the destruction of the anti-nutrient phytate.

Hans Stein, professor of animal science at the University of Illinois, leads a research team which has been studying the interactions between phytate, phytase, and calcium. “Currently, discussion in the swine industry is focused on calcium digestibility and formulating diets based on digestible calcium. Results of research indicate that phytase increases calcium digestibility, so this effect should be taken into consideration when it comes to diet formulation.”
