Abstract

Abstract Three studies were conducted evaluating the use of benzoic acid in swine diets. In experiment 1, 350 weanling barrows (DNA 200 × 400; initially 5.9 ± 0.04 kg) were allotted to one of the five dietary treatments with 14 pens per treatment. Diets were fed in three phases: phase 1 from weaning to day 10, phase 2 from days 10 to 18, and phase 3 from days 18 to 38. Treatment 1 contained no benzoic acid throughout all three phases (weaning to day 42). Treatment 2 included 0.50% benzoic acid throughout all three phases. Treatment 3 contained 0.50% benzoic acid in phases 1 and 2, and 0.25% benzoic acid in phase 3. Treatment 4 contained 0.50% benzoic acid in phases 1 and 2, and no benzoic acid in phase 3. Treatment 5 contained 0.50% benzoic acid in phase 1, 0.25% benzoic acid in phase 2, and no benzoic acid in phase 3. For the overall period, pigs fed 0.50% in the first two phases and 0.25% benzoic acid in the final phase had greater (P < 0.05) average daily gain (average daily gain) than pigs fed no benzoic acid through all three phases, or pigs fed 0.50% in the first two phases and no benzoic acid in the final phase, with pigs fed the other treatments intermediate. Pigs fed 0.50% in the first two phases and 0.25% benzoic acid in the final phase had improved (P < 0.05) gain-to-feed ratio (G:F) compared with pigs fed no benzoic acid throughout all three phases, pigs fed 0.50% in the first two phases and no benzoic acid in the third phase, or pigs fed 0.50%, 0.25%, and no benzoic acid, respectively. For experiment 2, a 101-d trial was conducted using two groups of 1,053 finishing pigs (2,106 total pigs; PIC 337 × 1,050; initially 33.3 ± 1.9 kg). Dietary treatments were corn–soybean meal-dried distillers grains with solubles-based with the addition of none, 0.25%, or 0.50% benzoic acid. Overall, pigs fed increasing benzoic acid had a tendency for increased average daily feed intake (linear, P = 0.083) but decreased G:F (linear, P < 0.05). In experiment 3, 2,162 finishing pigs (DNA 600 × PIC 1050; initially 31.4 ± 2.2 kg) were used in a 109-d trial. Dietary treatments were formulated with or without 0.25% benzoic acid. For the overall experimental period, pigs fed benzoic acid had increased (P < 0.05) G:F. In summary, feeding benzoic acid elicits improved growth performance when fed throughout the entire nursery period while improved G:F in growing-finishing pigs was observed in one experiment, but not in the other.

评估苯甲酸对保育猪和育成猪生长性能的影响

摘要对猪日粮中苯甲酸的使用进行了三项评估研究。在实验 1 中，350 头断奶仔猪（DNA 200 × 400；初始体重为 5.9 ± 0.04 千克）被分配到五个日粮处理之一，每个处理有 14 个猪栏。日粮分三个阶段饲喂：第 1 阶段从断奶到第 10 天，第 2 阶段从第 10 天到第 18 天，第 3 阶段从第 18 天到第 38 天。处理 1 在所有三个阶段（断奶至第 42 天）均不含苯甲酸。处理 2 在所有三个阶段中都含有 0.50%的苯甲酸。处理 3 在第 1 和第 2 阶段含有 0.50%的苯甲酸，在第 3 阶段含有 0.25%的苯甲酸。处理 4 第一和第二阶段含 0.50%苯甲酸，第三阶段不含苯甲酸。处理 5 第一阶段含 0.50%苯甲酸，第二阶段含 0.25%苯甲酸，第三阶段不含苯甲酸。在整个阶段中，前两个阶段饲喂 0.50%、最后一个阶段饲喂 0.25% 苯甲酸的猪的平均日增重（P < 0.05）高于三个阶段都不饲喂苯甲酸的猪，或前两个阶段饲喂 0.50%、最后一个阶段不饲喂苯甲酸的猪，而饲喂其他处理的猪则处于中间状态。与三个阶段都不喂苯甲酸、前两个阶段喂 0.50%、第三阶段不喂苯甲酸或分别喂 0.50%、0.25% 和不喂苯甲酸的猪相比，前两个阶段喂 0.50%、最后阶段喂 0.25%苯甲酸的猪的增重与饲料比（G:F）有所改善（P < 0.05）。在实验 2 中，对两组共 1,053 头育成猪进行了为期 101 天的试验（总计 2,106 头猪；PIC 337 × 1,050；初始体重为 33.3 ± 1.9 千克）。日粮处理以玉米-豆粕-带溶解物的干馏分谷物为基础，添加不含苯甲酸、0.25% 或 0.50% 的苯甲酸。总体而言，饲喂苯甲酸增加的猪有日平均采食量增加的趋势（线性，P = 0.083），但G:F下降（线性，P < 0.05）。在实验 3 中，2,162 头育成猪（DNA 600 × PIC 1050；初始体重为 31.4 ± 2.2 千克）参加了为期 109 天的试验。日粮中添加或不添加 0.25% 苯甲酸。在整个试验期间，饲喂苯甲酸的猪的 G:F 均有所增加（P < 0.05）。总之，在整个保育期饲喂苯甲酸可提高猪的生长性能，而在一项实验中，生长后期猪的 G:F 有所提高，但在另一项实验中则没有。

期刊介绍： Translational Animal Science (TAS) is the first open access-open review animal science journal, encompassing a broad scope of research topics in animal science. TAS focuses on translating basic science to innovation, and validation of these innovations by various segments of the allied animal industry. Readers of TAS will typically represent education, industry, and government, including research, teaching, administration, extension, management, quality assurance, product development, and technical services. Those interested in TAS typically include animal breeders, economists, embryologists, engineers, food scientists, geneticists, microbiologists, nutritionists, veterinarians, physiologists, processors, public health professionals, and others with an interest in animal production and applied aspects of animal sciences.
