Effects of Dietary Soybean Meal Concentration with Dietary Crude Protein Fixed at 12% on Growth and Carcass Performance of Finishing Pigs from 250 to 300 lb

Oats (Avena sativa L. cv. Hinoats, 14.6% crude protein, 4.66 Mcal GE/kg) were tested in digestion and feeding trials with growing–finishing pigs from 23 to 91 kg body weight. Up to 57 kg, groups of six crossbred pigs (3 male, 3 female) in a 3 × 3 factorial experiment were fed supplemented diets of Hinoats meal, Hinoats pellets or 2/3 Hinoats:1/3 wheat, each with one of three supplements: either 0.2% lysine plus 0.05% methionine, or with half levels of these amino acids plus 2% soybean meal, or 6% soybean meal. At 57 kg, the pigs were assigned from each grower ration to one of three finisher rations, these being the three grower rations supplemented only with amino acids. Feeding was allowed for three 1-h periods daily up to 57 kg body weight and for two 1-h periods thereafter. Pigs of 23–57 kg fed pellets had greater daily feed intakes than pigs fed meal or the meal ration containing wheat (1.90, 1.70, 1.77 kg, respectively) and grew faster (0.69, 0.60, 0.60 kg/day, respectively). From 57 kg body weight, performance was not affected by previous diet but pigs fed pellets ate more and grew faster than the others. Hinoats rations were efficiently utilized by the pigs. In separate digestion trials, Hinoats energy and protein were found to be 72 and 82% digestible, respectively.

The objective of this study was to evaluate the efficacy of supplementing a corn-wheat-soybean meal-based diet with a multicarbohydrase and phytase complex (MCPC) on growth performance, apparent total tract digestibility (ATTD) of nutrients, carcass traits, and meat quality in growing-finishing pigs. A total of 300 pigs (Duroc × Large White × Landrace; body weight = 25.3 ± 0.7 kg) were randomly allotted to three groups with 10 replicates of 10 pigs each. Pigs from three groups were fed positive control (PC) or negative control (NC), without or with MCPC diets, respectively. The MCPC supplied at least 1800, 1244, 6600, and 1000 units of xylanase, β-glucanase, α-arabinofuranosidase, and phytase per kilogram of diet, respectively. The NC diet was the PC diet but reduced in net energy (NE), digestible amino acids (dig. AA), digestible P (dig. P), and Ca by 74 kcal/kg, 7.0%, 0.134, and 0.119 percentage points, respectively. The diets were fed in 4 growth phases based on body weight (BW): phase 1: 25–50 kg, phase 2: 50–75 kg, phase 3: 75–100 kg, and phase 4: 100–135 kg. Compared to the PC, the NC diet decreased (p < 0.05) body weight gain, feed intake, and(or) feed to gain ratio during the growing/finishing phases 1, 2, 3, and 4. It also reduced (p < 0.05) the ATTD of crude protein, crude fat, P, and Ca of pigs. MCPC supplementation improved (p < 0.05) the body weight gain, feed intake, and(or) feed to gain ratio in phases 2, 3, and 4 and the ATTD of crude protein, crude fat, ash, P, and Ca for the NC diet. Additionally, dietary treatment had no effects on carcass traits and meat quality with the exception that the loin eye area in the NC plus MCPC diet was higher (p < 0.05) than the NC diet. In conclusion, the addition of MCPC to a corn-soybean meal-wheat-based diet reduced in energy and nutrients improved the growth performance and nutrient digestibility but had little effect on carcass traits and meat quality in growing-finishing pigs.

Protein Diets

: This review explores the premise that non-bound (synthetic and crystalline) amino acids are alternatives to soybean meal, the dominant source of protein, in diets for broiler chickens. Non-bound essential and non-essential amino acids can partially replace soybean meal so that requirements are still met but dietary crude protein levels are reduced. This review considers the production of non-bound amino acids, soybeans, and soybean meal and discusses the concept of reduced-crude protein diets. There is a focus on specific amino acids, including glycine, serine, threonine, and branched-chain amino acids, because they may be pivotal to the successful development of reduced-crude protein diets. Presently, moderate dietary crude protein reductions of approximately 30 g/kg are feasible, but more radical reductions compromise broiler performance. In theory, an ‘ideal’ amino acid profile would prevent this, but this is not necessarily the case in practice. The dependence of the chicken-meat industry on soybean meal will be halved if crude protein reductions in the order of 50 g/kg are attained without compromising the growth performance of broiler chickens. In this event, synthetic and crystalline, or non-bound, amino acids will become viable alternatives to soybean meal in chicken-meat production.

The Ideal

Due to the introduction of more stringent environmental controls through the implementation of current and impending environmental legislation, dietary crude protein (CP) levels for finishing pigs are an important area of research. Canh et al (1998) reported that nitrogen (N) excretion could be reduced through lowering CP levels and the aim of this study was to investigate the effect of decreasing CP levels of diets containing two levels of lysine (while maintaining the ideal protein balance through amino acid supplementation) on nutrient digestibility and N balance.
