Effect of dietary sucrose on growth performance of growing pigs

1. In the growing-finishing pig diet, 1.5% sucrose was added to the test group. Compared with the non-added control group, the daily weight gain can be increased by 8.3%. (P people observed in pig production practice that pigs generally prefer to eat sweet-tasted feed. For this reason, in recent years, many domestic and foreign pig farms have The use of saccharin as a feed additive for pigs has not yet been reported as a feed additive for grow-finishing pigs.To further explore the effect of sucrose as a feed additive for finishing pigs on the weight gain of pigs, to broaden the benefits for pig farmers The source of feed additives provided the basis. From March to June 1999, the author conducted a comparative study on the growth and finishing pigs reared by specialized pig raising households in Mingshui Town of this Municipality. The effects of weight gain 1 Materials and methods 1.1 Test time The trial was a 7-day pretest period from March 10 to March 16, 1999, and a formal trial period from March 17 to June 15, 90 days. 1.2 Experimental animals and sites Trial cross-breeding finishing pigs with a length of X, a long X, and a X-day cross of about 80 days of age were selected for this experiment in a pig raising farm in Mingshui Town of this Municipality. Pigs growing and finishing pigs , Select 20 pigs with the same or similar body weight and age, and randomly divide them into two groups of 10 pigs each with two laps and 5 pigs per lap. (The ratio of males and females is the same in both groups and has been castrated. In the diet, 1.5% sucrose was added to the test group, and the control group was not added. 1.4 Feeding management The test pigsty was a brick structure. The test was conducted with two laps per group. Both groups were in the same The pigs were fed by the same piggery, and the feeds were fed with raw water, mixed with water, and then mixed with water. The amount of feed was not limited, the feed was fed 3 times a day, and food and water were freely eaten. The other management measures were the same for both groups. During the trial period, the designated person shall be responsible for doing a good job of recording test data and observation of feeding conditions, and the fasting of the test shall be started and completed. After the test is completed, the two groups shall be calculated respectively for daily weight gain, feed-to-weight ratio and economic benefits. Analysis 2.1 Feeding observation During the trial period, the experimental group that added sucrose to the diets showed that the growing-finishing pigs showed favorable food, the feed intake increased, the feed intake was fast, and the excreted manure was normal, and no abnormalities were observed. 2 weight gain speed test for the whole period of the two groups The weight gain results for growing-finishing pigs are shown in Table 2. 2.3 Daily gains As can be seen from Table 2, diets fed with sucrose in the test group had average daily gains per head of growing-finishing pigs throughout the trial. 67579g, compared with 62365g in the control group, the test group increased daily gain by 8.3% compared to the control group. The t-test showed significant difference between the two groups (P2.4 feed weight ratio can also be seen in Table 2 in the diet. In the test group fed with sucrose, the feed-to-weight ratio was 3.38:1 in the whole test period and 3.54:1 in the control group. Each kg of body weight gained was 0.16 kg less than the control group, which increased feed utilization by 4.5%. t test, the difference between the two groups was significant (P 2.5 economic benefit from the test can be seen in the experimental group added sucrose diet, during the trial period for each finishing pig averaged 149.12 yuan gross profit, while the control group was not added 134.44 Yuan, the test group increased economic efficiency by 10.9% compared with the control group, and the economic benefit was obvious. 3 Summary 3.1 This experiment confirmed that adding a certain amount of sucrose in the diet of growing-finishing pigs can not only enhance the palatability of the feed and feed intake of pigs, but also increase the daily gain of pigs. Feed use efficiency and economic benefits have some good results, which proves that sucrose is a good nutritive food attractant for growing pigs. 3.2 Since there are few groups and time is short in this experiment, the optimal additive feeding amount in the diet has not yet been screened. This subject can be further tested in the pig production in the future.
