Pigs

Improves daily weight gains, enhances meat quality, strengthens native immunity ! Growfeed

Feeding experiment on pigs

  • Performing institution : Gyeongsangbuk-do Livestock Technology Reseach Center
  • Experiment period : May. 16, 2011 ~ Aug. 15, 2011 (90 days)
  • Experiment species : 26 heads of castrated pigs (three-way crossbreed of Landrace and Duroc) and divided into two groups with 13 heads per group
  • Experiment method : Control group (no addition of Growfeed Well Farm to feedstuff)
  • Experimental group (added 0.3% of Growfeed Well Farm to feedstuff)

Changes in the weight and weight gain and daily weight gain during the whole experiment period

  • The total weight gain per head of the experimental group was 29.5kg which was greater than the control group.
  • The daily weight gain per head of the experimental group was 1.03kg while that of the control group was 0.93kg.
  • he weight at the starting age was similar between the two groups but after one month (30 days), the experimental group showed better weights than the control group. At 90 days from the start of the experiment, the weight of the experimental group was about 6kg heavier than that of the control group.

Total and daily feed intake per head during the whole experiment period

  • The daily intake per head of the experimental group was 3.38kg which was lower than that of the control group (3.43kg) and the experimental group showed a lower feed conversion rate (3.28) compared to the control group (3.95).

Physicochemical changes in the serum

  • The experimental group showed lower total cholesterol levels in the blood than the control group.
  • The experimental group showed greater glucose and lgG contents than the control group.
  • experimental group also showed lower GOT and GPT than the control group indicating better liver functions.

Carcass performance

  • The experimental group showed a greater carcass weight than the control group and the back-fat thickness of the experimental group was significantly lower than that of the control group.
  • This demonstrates the excellent of Macsumsuk and it appears that the addition of Macsumsuk will greatly contribute to the improvement of the weight gain and meat quality of pork.

Physicochemical and sensory test results of pork

  • The experimental group showed greater heating loss and water-holding capacity than the control group. In particular, the cholesterol content of the experimental group was significantly lower than that of the control group suggesting that the addition of Macsumsuk has positive effects on the muscle and fat characteristics of pork.

Fatty acid composition of pork

  • The control group showed greater saturated fatty acid contents than the experimental group, whereas the experimental group showed greater unsaturated fatty acid contents than the control group. It was found that the excessive intake of saturated fatty acid has increased the cholesterol level.
  • Unsaturated fatty acid is effective in the prevention of adult diseases as it reduces the cholesterol in the blood.
