The effect of CreBuilder® on the performance and carcass traits
In Chinese Simmental bulls
All plant-based diets cannot meet ruminant creatine requirements, resulting in decreased performance. Uncoated guanidinoacetic acid is quickly degraded by rumen microorganisms as non-protein nitrogen, and rumen bypass ratio is very low. 3. CreBuilder® is used microcapsule multilayer coating process, and provides more metabolizable guanidinoacetic acid. CreBuilder® is used in ruminant feed to ensure adequate supply of creatine, improve energy efficiency, promote protein deposition, improve performance, slaughter performance, and meat quality, and relieve production stress. The purpose of this experiment is to study the effect of CreBuilder® on the performance and carcass traits in Chinese Simmental bulls.
The CreBuilder® in this test was provided by Beijing Gendone Biotechnology Co., Ltd.
Experimental animals and design
A total of 10 Chinese Simmental bulls with initial body weight about 500 kg were allotted to 2 treatments with 5 cattle per pen. The control group was fed a basal diet (total mixed ration), and the test group added 1200 g CreBuilder® per kg concentrate supplement in the basal diet. The feeding trial lasted 90 days.
The experiment was conducted in a farm (Chifeng, Neimenggu Province, China). Cattles were fed twice a day in the morning and evening, with free drinking water.
Measurement indicators and methods
At the beginning of the feeding experiment, 10 bulls were weighed. On the 90th day, all bulls were transported to a nearby commercial abattoir and weighed again to calculate the average daily gain during the trial period. Bulls were electrically stunned and then killed by exsanguination. Carcasses obtained according to the normal industry standard were weighed.
The test data was compared and analyzed using EXCLE (2013) software.
Dietary supplementation CreBuilder® at 1200 g CreBuilder® per kg concentrate supplement in the basal diet increases daily gain by 160 grams and dressing percentage by 1.8% for Chinese Simmental bulls.
