Effect of Fiber Source and Crude Protein Level on Nursery Pig Performance

Best diet of the fish is the sole of production of aquaculture. Growth performance of Clarias gariepinus on the basis of formulated feed supply was carried out from 7th March to 6th May, 2019 in the laboratory of P.G.Campus, Biratnagar in which 130 juveniles (each of 10±0.11 g.) of catfish were cultured in 13 aquaria feeding with treatment diets having crude protein level 35%, 40%, 45% and 50% for treatment and commercial diet for control. There are no significant differences between the water quality parameters and body weight gain (p>0.05) in all treatments. The highest body weight gain (7.31±0.11 g; 65.20%) and SGR (13.051±1.15 g) was observed in fish fed with T C (45% protein level). This value was lowered than value of control(C) i.e. 7.59±0 g; 69.88% and 13.55±0 g respectively. Feed conversion ratio (FCR) was best (13.28±1.89 g) in T D (50% protein level feed). Its value was larger (7.52±1.11 g) in T C than C (7.15±0 g). Mortality rate was highest in T C and C i.e. 30% and lowest in T A and T B i.e. 23.33%. Weight gain of the fish increased with increasing protein level in diet till crude protein level 45% then it was dropped at the diet with protein level 50%. The best weight gain was observed in 7th week having crude protein level 45%. The diet with protein level 45% is suggested for farmers concerning the fish (Clarias gariepinus) in the aquaculture.

Main Effects

Abstract A total of 360 pigs (DNA 200′400, initially 5.0 kg) were used in a 45-d growth trial to determine the effects of fiber source and crude protein (CP) level in diets without pharmacological levels of ZnO on nursery pig growth performance and fecal dry matter (DM). Pigs were randomly assigned to 1 of 8 treatments with 5 pigs/pen and 9 pens/treatment. Treatments were arranged in a 2×4 factorial with main effects of CP (21 or 18%) and fiber source [none, coarse wheat bran (CWB), oat hulls, or cellulose (Arbocel, J. Rettenmaier USA, Schoolcraft, MI)]. Fiber source was added to equalize the level of insoluble fiber contributed from 4% CWB, resulting in the addition of 1.85% oat hulls or 1.55% cellulose. Diets were fed in two phases (d 0 to 10 and 10 to 24) followed by a common diet (d 24 to 45). The 21% CP diets contained 1.40% SID Lys in phase 1 and 1.35% SID Lys in phase 2. Treatment diets were formulated to a maximum SID Lys:digestible CP level of 6.35%, thus SID Lys decreased in the 18% CP (1.25% SID Lys) diets. Data were analyzed using the lmer function in R. No fiber source × CP level interactions (P >0.05) were observed. Decreasing dietary CP decreased (P = 0.05) ADG, G:F, and d 24 BW. Overall, ADG and d 45 BW decreased (P < 0.05) for pigs fed 18% CP diets. No main effects of fiber source were observed for growth performance throughout the study. Fecal DM increased (P < 0.05) for pigs fed added cellulose compared to pigs fed no fiber or CWB in the experimental period. In conclusion, reducing dietary CP decreased growth performance and the inclusion of cellulose improved fecal DM of nursery pigs.

Crude Protein Level

The aim of this study was to evaluate the growth of and feed utilization by Boer x Kacang crosses goats fed on total mixed ration differing in protein and energy levels. Four total mixed rations combination were formulated to contain 16 and 18% crude protein and 2650 and 2850 Kcal ME/ kg DM (dried matter) energy density. Twenty-eight male Boer x Kacang crosses goats (14.5 ± 1.14 kg) and of age ranging from 4 to 5 months were randomly allocated to one of these four TMRs (total mixed rations) (7 animals/TMR). The effects of dietary treatment were assessed using the general linear model and significance of the diet effects was detected using Duncan’s multiple range test. Dry matter intake increased as metabolizable energy density of diet increased from 2650 to 2850 Kcal/kg DM, but it is not affected by increasing crude protein level from 16 to 18%. The average daily gains were not improved (P>0.05) as the crude protein levels and metabolizable energy density of diet increased. Crude protein levels and ME density did not affect (P>0.05) the DM, OM and energy digestibility, but NDF digestibility was affected by the ME density of diets (P<0.05). Daily N intakes were greater (P<0.0%) in goats received diets higher in the crude protein and metabolizable energy levels. At this high rate of feed intake this type of goats are able to gain optimally when offered feed with crude protein level of 16% and metabolizable energy density of 2850 Kcal/kg DM.
