- a,bValues in the same row with이it a common supscript are significantly different (p<0.05).
제안 방법
- , 1975; Boychuk, 1997; Thacker, 1999). The objectives of the present study were to investigate the effects of replacing wheat and maize with micronized dehulled barley (MDB) on pig growth performance, plasma urea nitrogen (PUN) levels, carcass cut and organ weight.
- The hot carcass was weighed, chilled at 1 ℃ for 48 h, and carcass measurements were taken. The evaluation at market included the weights of half carcass, head, loin+belly, shoulder, picnic, butt, hock, trim, fat trimmings, spareribs, leg, riblets, back fat, liver, stomach, small intestine and large intestine.
- The model used for average daily feed intake and feed efficiency was Yijk= μ+ti+Sj+rj+tSij+eijk, where Yijk=the average daily gain per pig on the ith diet in the jth sex within the kth room, μ=the overall mean, tj=the effect of the ith treatment, Sj=the effect of the jth sex, rj=the effect of the kth room, tSij=the effect of the interaction of the ith treatment and the jth sex, eijk=random error.

Data from the digestibility trial were analysed with the ANOVA procedures of the Statistical Analysis System (SAS Institute Inc., 1989).
이론/모형
- Crude protein, gross energy, dry matter and neutral detergent fibre of the feeds were determined according to the AOAC (1986). Starch was determined by the method of Technicon (1978). Gross energy was determined by using an adiabatic oxygen bomb calorimeter.
성능/효과
- Treatment diets differed by the amount of MDB that was included as part of the overall grain portion of the diet (table 3). The maize and MDB ratio in the three diets were 100% maize; 50% maize+50% MDB; 100% MDB. Diet preparation and administration were the same as those of experiment 1.
- There were no differences (p>0.05) in growth performance, except for a significant reduction (p<0.05) in ADFI with the 100% MDB based diet.
- There were no differences (p그0.05) in growth performance, except for a significant reduction (p<0.05) in ADFI with the 100% MDB based diet.
- The PUN levels of the pigs measured at 60 kg live weight indicated that pigs fed MDB based diet had a lower PUN concentration (p<0.01) compared to those fed the wheat-based diet.
- , 1995). The PUN levels of the pigs measured at 60 kg live weight indicated that pigs fed MDB based diet had a lower PUN concentration (p<0.01) compared to those fed the wheat-based diet. There appeared to be a reciprocal relationship between the inclusion levels of MDB in the diet and the corresponding PUN concentration.
- The ADFI for castrates on average across treatments at the starter, grower and finisher phases was 621, 1335, 3359 g and for gilts only 574, There was no sex X MDB interaction, evaluation by the weights of different of organ, showed that diet treatments (p>0.05) the carcass characteristics and organ weight of the grower finisher pigs (table 8).
- 5 percent ADG improvement for pigs fed a MDB based diet from 22 to 50 kg live weight, compared with a wheat-based diet. The results of the present study suggest that the wheat or maize in the starter, grower and finisher pig diets can be replaced partly or totally by MDB without affecting performance. Importantly, the ADG was increased (p<0.
- The author explained this by the observed increase in meal viscosity. However, only one significantly reduced feed intake was observed in this study for the pigs in growing phase fed the 100% MDB based diet compared with 100% of wheat based diet, and the daily gain and feed efficiency were not affected.
