“…2). The improved nutrient digestibility in this study was similar to results reported by previous studies [11,27,28]. Addition of exogenous enzymes in non-ruminant diets has been using for several benefits including, minimization of anti-nutritional effects and maximization of nutrient utilization, to improve nutrient utilization and growth performance of non-ruminants [29] because the digestive system and the secretion and activity of digestive enzymes of young non-ruminants are immature and insufficient Sangwoo Park, et al Each value is the mean of 5 replicates (5 pigs/pen).…”

This study was conducted to evaluate effects of dietary protease (PR) on growth performance, nutrient digestibility, and intestinal morphology of weaned pigs. A total of 75 weaned pigs [7.06 ± 0.18 kg of average body weight (BW); 28 day old] were randomly allotted to 3 dietary treatments in a randomized complete block design (blocks = BW and sex): a diet based on corn and soybean meal to meet the requirement of crude protein (CP) as a positive control (PC; CP = 24.49%), a low protein diet as a negative control (NC; CP = 22.51%), and NC + 0.02% PR. The PR used in this study was a commercial product containing 75,000 protease units/g derived from Nocardiopsis prasina produced in Bacillus licheniformis. Pigs were fed the dietary treatments for 6 weeks and the diets containing 0.2% chromic oxide for the last week of this study. Blood, feces, ileal digesta, and ileum samples were collected from randomly selected two pigs in each pen on respective time points. Measurements were growth performance, apparent ileal digestibility (AID) and apparent total tract digestibility (ATTD) of dry matter (DM), CP, and energy, frequency of diarrhea, packed cell volume (PCV), and ileal morphology of weaned pigs. Pigs fed PC and PR had higher (p < 0.05) final BW, average daily gain (ADG), and gain to feed ratio (G:F) during overall experimental period than those fed NC. Pigs fed PC and PR had higher (p < 0.05) AID or ATTD of DM, CP, or energy than those fed NC. Moreover, pigs fed PR had higher ratio between villus height and crypt depth (p < 0.05) and number of goblet cells (p < 0.05) than those fed NC. Addition of PR decreased (p < 0.05) frequency of diarrhea for the first two weeks after weaning compared with PC and NC. In addition, pigs fed PR had lower (p < 0.05) PCV on d 14 after weaning than those fed PC and NC. In conclusion, addition of PR in nursery diets with a low protein level significantly improved growth performance, nutrient digestibility, and intestinal morphology of weaned pigs.

“…Coated proteases in diets of weaned pigs showed improved apparent total tract digestibility of nitrogen (N) and energy. It also resulted in improved AID of some indispensable amino acids, nutrients (Pan et al, 2016), crude protein and standardized ileal digestibility (Yu et al, 2016). Other studies confirmed that weaned pigs fed protease supplemented diets improved nutrient digestibility and growth performance ( Zuo et al, 2015;Tactacan et al, 2016).…”

A study was conducted to investigate the effects of dietary protease supplementation on growth performance and carcass characteristics of growing-finishing pigs that started with a lower bodyweight than pigs in the control group. A total of 96 growing pigs (initial bodyweight (BW) 31.6 ± 2.97 kg) were allotted to two dietary treatments (48 pigs/treatment, 8 pigs/pen) with different initial BW (34.37 vs. 28.78 kg). The dietary treatments were a control diet (CON), based on maize and soybean meal (grower diets) and wheat (finisher diets), and a protease diet (PRO), which was the CON diet to which 0.02% protease was added. Pigs were fed these dietary treatments (high BW-CON, low BW-PRO) for 12 weeks, comprising six weeks growing and six weeks finishing. In the growing period, PRO had higher average daily gain (ADG) and gain to feed (G:F) ratio than CON. The significant difference in bodyweight that was observed at the beginning of the experiment between the treatment groups was still observed at the end of the growing period. In the finishing period, PRO had reduced feed intake, average daily feed intake (ADFI), and increased G:F ratio compared with CON. At the end of the experiment, there was no significant difference in BW between the treatment groups as a result of lower feed intake and ADFI and higher ADG and G:F ratio. In addition, there were no differences in carcass characteristics between the groups. Therefore, standalone protease supplementation may positively affect the growth performance of growing-finishing pigs through improved feed efficiency without negative effects on carcass characteristics. ______________________________________________________________________________________

“…Assessing the nutritional efficiency is a critical factor for animal protein production to understand the nutrient utilization and optimizing the nutrients in the ration, as well as reducing the environmental pollution through undigested nutrients [1]. In the present study, addition of CC protease had shown significantly (P < 0.1) lesser energy and protein intake than other treatment groups [7] (Table 3).…”

“…Most of the proteins in soybean are easily digested, except some, like glycinin, protease inhibitors and antigenic proteins which may predispose the intestinal damage and impair the immune function [1]. With the development of enzyme technologies, protease application helps to enhance the protein and amino acid digestibility [2], as well encourages the addition of alternate protein feed materials which helps to reduce the feed cost.…”

Protease as feed additive is being used in poultry production as a partial replacement for protein sources for cost efficiency and reducing nitrogen excretion. However, diverse proteases may yield different responses under field conditions. A pellet diet study was conducted in Cobb broilers to assess the impact of coated compound (CC) and mono-component (MC) proteases with 5% replacement of digestible amino acids and 0.9% crude protein. Birds fed positive control diet had a better growth than those fed negative control diet, regardless of enzyme supplementation. However, CC protease had shown feed conversion ratio (FCR) like control in a reformulated diet, whereas negative control and MC protease missed to gain the feed conversion. In measures of nutritional efficiency, like energy efficiency, protein efficiency and amino acids efficiency (lysine and methionine), the CC protease proved to be better than MC protease. In terms of European efficiency factor (EEF), control and CC protease elicited a closer response, whereas the other two groups showed a drop. In this study, CC protease allowed partial substitution of digestible amino acids and crude protein, while maintaining feed efficiency and animal performance. It could be concluded that incorporating CC proteases is an efficient choice to maximize the utilization feed material resources and efficiency in animal protein production.
