[0046] Test Example 1
[0047] This test is to verify the effects of the nitraria tangutorum bobr. fruit extract on the production performance and meat quality of sheep, and the details are as follows:
[0048] (1) Test design
[0049] Ninety 4- to 5-month-old male Hu sheep lambs with similar body weights and body conditions (38.76±2.52 kg) were selected and randomly divided into 3 groups, with 3 pens (3 m×6 m) in each group and 10 lambs in each pen. Three levels of nitraria tangutorum bobr. fruit extract, namely 0 g / kg (CON group), 10 g / kg (NT1 group), and 20 g / kg (NT2 group), were provided. On the 60th day of the test, 10 lambs in each group were separately placed in metabolism cages for feeding until the end of the test. Feeding was carried out at 6:00 am and 16:00 pm every day, and the test lambs had free access to food and water. The test diet was as shown in Table 1 in Example 2. To ensure that the nitraria tangutorum bobr. fruit extract could be completely consumed, the nitraria tangutorum bobr. fruit extract was mixed with the concentrate and fed in the morning every day. This test lasted for 130 days, including a 10-day adaptation period.
[0050] (2) Sample collection
[0051] The initial weight of each lamb was recorded, and then the fasting weight was measured every 30 days. From the 61st day, the remaining feed of the lambs in the metabolism cages was collected before morning feeding every day for calculating the daily weight gain, dry matter intake, and feed-to-weight ratio.
[0052] Sheep were fasted for 12 h before slaughter. After slaughter, the carcass was split in half, and then cut between the 12th and 13th ribs on the left side of the carcass. The subcutaneous backfat thickness was measured using a vernier caliper. The cross-sectional area of the longissimus dorsi muscle on the 12th and 13th rib vertebrae was traced on sulfuric acid paper. Samples of the longissimus dorsi muscle from the left half of the carcass were collected for determination of pH value, meat color, cooking loss, water loss rate, cooked meat rate, and texture properties, as well as fatty acids and conventional muscle nutrient components.
[0053] The results of growth performance and carcass traits are shown in Table 2:
