| dc.description.abstract | ABSTRACT: Two 2 X 2 f a c t o r i a l e x p e r i m e n t s were c o n d u c t e d w i t h growing and f i n i s h i n g Large White Y o r k s h i r e barrows t o d e t e r - mine optimum e n e r g y : p r o t e i n r a t i o s and t o d e v e l o p r e g r e s s i o n e q u a t i o n e t o p r e d i c t t o t a l body water and FFEE weight from TOH s p a c e and body p r o t e i n , fat o r ash from Tori Rpace and l i v e weight st 35 and 65 Kg. I n e x p e r i m e n t 1, f o r t y barrow8 were f et3 d i e ta s u p p l y - i n g 16y c r u d e p r o t e i n (on fresh b a s i s ) with 3.0 (GP-1 ) o r 3.3 (GD-2) e n d 189% c r u d e p r o t e i n wi t h 3.0 (GT-3)o r 3.3(~~-) 4 #.cal EE/K~. Energy had a s i g n i f i c a n t (Y~0.05) e f f e c t on feed conrumption. Feed e f f i c i e n c y and cost/kg gain of GC-1 and GI!-4 were s u p e r i o r t o GO-2 and GI)-3. Lcvel of encrgj (PJ 0.01 ) influenced digestibilitiea of Illv, CP, EE and NFE. Digestibillties of DM and WFE of GD-2 were hieher (F L, 0.01 ) than GI!-1 o r GI!-3. Digest ibili tie8 of DF, CP sr d NFE of GP-4 were higher (P-, 0.05 ) than GI)-3. Enera t protein ratio8 did not a f f e c t nitrogen r e t e n t i o n . Level of p r o t e i n and E X P i n t e r a c t i o n influenced r e t e n t i o n of absorbed calcium and phosphorus. Retention of absorbed calcium was lower f o r treatment 2 than 1, 3 or 4. Retention of absorbed phosphorus was higher (Pr 0.01 ) f o r pigs fed G2-4 than t h o s e f e d GI)-2 o r GT-3. The percent l o i n + hen1 was hipher (P C. 10) i n treatment 4 than 1 t o 3. Fnergy denslty and I? X 'P inter- .jction influenced percentare of body water which was high (P -0.0: ) i n pigs fed GT-3 than those fed Gr-4. :Tg and NFF v a l u e s of grower d i e t s 1 t o 3 were 0.80, 1.32; 0.79, 1.40; 0.59, 1.30 end 0.82, 1.44 r e s p e c t i v e l y . The c o r r e l a t i o n coeff lcierlte (r'p ) be tween t o t a l kody wa t e r o r FFEB weight and TYrT space were 0.93C4 (~,-_2.01) and 0.?168 (P. -0.01 ) respectlvely. The multl ple correlat i o n c o e f f i c i e n t s (~'6)b etween t o t a l body fat o r ash and TIOH epees and l i v e weight were 0.6928 (P / 0.05 ) and 0.7197 (2~0.05 ) respectively. In experiment 2, 24 barrows of experiment 1 were shif tsd to d l e t e eupplylng 14% CP with 3.0 (FC-I ) or 3.3 (FD-2 ) and 16% CP with 3.0 (FD-3 ) or 3.3 (FD-4 ) M.cal EE /~g. Energy density and E X P i n t e r a c t i o n Influenced feed coneurnptlon which was lower (PLO. 05) i n p i g s fed PC-4 than those fed FT-3. Peed efficiency and coet/Kg gain of FC-1 wee euperior t o t h e o t h e r diete. Energy level affected digestibilitiee of EM, CP and VE which were hiaher (P 0.01 ) f o r FC-2 than FC-1. The l e v e l of energy alp:ni fican tly (P. 0.05 ) influenced nitrogen reten tion. The retention of absorbed-N was lower (P - 0.10) i n treatment 3 than In 2 or 4. Energy l e v e l had a s i g n i f i c a n t (F 0.05) e f f e c t on calcium and phosphorue reten tion. Yowevcr, re tention of absorbed calcium o r phosr~horus among the treatment was cimilar. Level of protein had 8 s i g n i f i c a n t (P -. 0.05 ) e f f e c t on dressing percentage. Energy, protein and E X P intera c t i o n Inf luenc ed loin eye area (cm 2 ) which was s i g n i f i - c a n t l y greater (PL 0.05) i n treatment1 than i n 2 t o 4. The body f a t content in pigs fed FC-2 wee hi~her (f G.10) than t h o s e f e d FD-1. The eeh cont~nt of pigs fed FD-4 we8 lower (?lo. 01 ) than thoae fad FD-1 or FC-3. Level of energy (P i0.01 ) a s well as protein (P.( 0.05 ) had e s i g n i f i c a n t e f f e c t on ash content. The NEgend NEF values of the f i n i s h e r diete 1 t o 4 were 0.69, 0.88; 0.95, 1.06; O.W, 0.91 and 0.87, 0.94 respectively. The c o r r e l a t i o n c o e f f i c i e n t s (rts ) between t o t a l body water o r FPEB weight and TOH epece were 0.8697 (P L 0.01 ) and 0.6996 (PL 0.01 ) respectively. The multiple c o r r e l a t i o n coef ficiente (R ) between body p r o t e i n o r body f a t or aeh and T H apace and l i v e weight were not significent (PB0.05). The optimum energy :protein r a t i o s f o r grower and f i n i s h e r pigs were 162 to 185 and 204 to 213 Kilocaloriee percentage u n i t s respectively. Prediction of body composition fro^ the regression equctions t h a t were developed was quite precise at 35 Kg but not a t 65 Kg body weight | en_US |
