Effects of Feed Condiment on Feed Intake and Growth Performance of Lambs
ABSTRACT: The purpose of this experiment was to study the effects of different feed condiments on feed intake and growth performance of lambs. A single factor design was used to divide 72 newborn lambs from 36 ewes into 6 groups (3 replicates, each replicate from 4 lambs from 2 ewes). They were randomly assigned to 6 treatments (A- control, B- compound sweetener 150g/t, C- apple banana flavoring agent 500g/t, D- breast milk flavor agent 500g/t, E- pure milk flavor agent 500g/t and F- sweetener). 150 g/t + 500 g/t of pure milk flavoring agent, 8-28 days of supplementary feeding. The results showed that the feeding intake (ADFI) of each flavoring agent group increased by 49.91%, 135.46%, 69.81%, 29.72% and 81.62% in 8-28 days, respectively, compared with the control group; the feeding time and duration of 8:00-16:00 and 16:00-24:00 in group C were significantly higher than those in group A (p < 0.01), 0:00-8:00 also showed a trend higher than that in group A (p = 0.08); the body weight of lambs in group C increased by 3.5%, 1.62% in 28 days, respectively, compared with the control group. ADG increased by 7.8%, 25.9%, 13.9%, 10.6% and 15.6% respectively in 1-28 days compared with the control group. Adding 5 kinds of flavoring agents to the supplemental feed of 8-28d Duhan lambs can improve the intake and growth performance of lamb. Among them, apple banana flavor is the best, followed by compound sweetener and pig breast milk flavor agent.
The effects of apple and banana flavoring agents on feed intake and growth performance of lambs were studied. Twenty-four newborn Small-tailed Han lambs from 12 ewes (all twin lambs) were divided into four groups (three repeats each, two lambs from one ewe). The control group (G) and three apple banana flavor additives (H-250g/t, I-500g/t, J-750g/t) were treated with supplementary feeding for 8-28 days. The results showed that the ADFI of apple banana banana flavoring agent group increased by 10.4%, 64.4% and 58.6% in 8-28 days, respectively, compared with the control group. The feeding time of lambs in group I and J was significantly higher than that in group G and H (p < 0.01); the average body weight of lambs in group I and J at 21 and 28 days was not significantly different (p > 0.05), but significantly higher than that in group G and H (p < 0.01), and the ADG at 1-28 days was about the same level, which was significantly higher than that in group G (p < 0.01). Group H, group H (p < 0.01), and group H were also significantly higher than group G (p < 0.01). The addition of 250 g/t, 500 g/t and 750 g/t apple banana flavoring agent in the supplementary feed of Small-tail Han sheep for 8-28 days could improve the intake and growth performance of lambs, and 500 g/t was the appropriate amount.
