The objective of this study was to examine the effectiveness of a novel 3-molecule boar pheromone (BOARBETTER, BB,) to improve sow reproductive performance (breeding, conception, farrowing rates, pigs born alive, stillborn, mummies and total born). Data from 12 commercial farm sites were used to evaluate the effectiveness of BB. Each farm was used as the experimental unit in the meta-analyses. Individual sows records were collected, merged and analyzed in overall analyses. Relative to CON, BB increased the number of total born pigs per litter (13.81 ± 0.11 vs. 14.30 ± 0.11 pigs/litter, respectively; < 0.01) and the number of pigs born alive (12.76 ± 0.14 vs. 13.13 ± 0.14 pigs/litter, respectively; < 0.05). In the merged dataset analyses, the parity by treatment interaction was significant for total pigs and pigs born alive per litter ( < 0.01). In parities one through three, treatment with BB increased total pigs born by 0.88 per litter, and pigs born alive per litter by 0.73 pigs per litter ( < 0.05). However, BB had no effect on these parameters in sows from parities four through six. BOARBETTER increased reproductive success, is cost effective, safe, and can meaningfully improve sow reproductive success and performance.
本研究的目的是检验一种新型三分子公猪信息素(BOARBETTER,BB)对提高母猪繁殖性能(配种、受孕、产仔率、活产仔猪数、死产仔猪数、木乃伊胎数和总产仔数)的有效性。来自12个商业农场的数据用于评估BB的有效性。在荟萃分析中,每个农场被用作实验单位。收集个体母猪记录,合并并进行总体分析。与对照组相比,BB增加了每窝总产仔数(分别为13.81±0.11头/窝和14.30±0.11头/窝;P<0.01)以及活产仔猪数(分别为12.76±0.14头/窝和13.13±0.14头/窝;P<0.05)。在合并数据集分析中,胎次与处理的交互作用对每窝总产仔数和活产仔猪数具有显著影响(P<0.01)。在第一至三胎中,用BB处理使每窝总产仔数增加0.88头,每窝活产仔猪数增加0.73头(P<0.05)。然而,BB对第四至六胎母猪的这些参数没有影响。BOARBETTER提高了繁殖成功率,具有成本效益、安全,并且可以显著提高母猪的繁殖成功率和性能。
