Abstract

ABSTRACT The objective of this study was to evaluate the economic viability of L-arginine supplementation in diets for sows during the lactation phase. A descriptive case study was carried out to identify the economic viability of the supplementation of L-arginine in the lactation ration, in relation to the control diet, on the productive performance of hyper prolific sows and their litters. The study was carried out on a commercial farm located in the state of Minas Gerais. It analyzed feasibility criteria such as the marginal physical product (MPPg) and gross margin (GM) in the scenario of technical and economic efficiency, which were compared to the GM in the control group. Technical efficiency was established at 0.71% of L-arginine in daily feed intake according to previous fieldwork by the authors, while economic efficiency obtained in this study was 0.43% supplementation. The relationship between the L-arginine price and the sale price of the piglets directly determined the economic viability, compared to the control group. Thus, initially considering the price of a piglet as R$ 9.76/kg, the cost of L-arginine should not exceed 6.61 times this value; that is, it is estimated at up to R$ 64.50. Therefore, at the final price of L-arginine of R$ 54.88, a piglet should be sold at a price of R$ 8.30/kg to make the supplementation of L-arginine in the diet of lactation-phase swine economically possible.
泌乳期母猪饲粮中添加l -精氨酸的经济可行性
摘要本研究的目的是评估在泌乳期母猪饲粮中添加l -精氨酸的经济可行性。为了确定在泌乳日粮中添加l -精氨酸相对于对照日粮对高产母猪及其窝仔生产性能的经济可行性,进行了一项描述性案例研究。这项研究是在米纳斯吉拉斯州的一个商业农场进行的。分析了技术经济效率情景下的边际实物产品(MPPg)和毛利率(GM)等可行性标准,并与对照组的GM进行了比较。根据作者以往的野外调查,确定了日采食量中添加0.71% l -精氨酸时的技术效率,而本研究中获得的经济效率为添加0.43%。与对照组相比,l -精氨酸价格与仔猪销售价格之间的关系直接决定了仔猪的经济生存能力。因此,最初考虑仔猪价格为9.76雷亚尔/公斤,l -精氨酸的成本不应超过该值的6.61倍;也就是说,估计最高可达64.50雷亚尔。因此,在l -精氨酸最终价格为54.88雷亚尔的情况下,为使l -精氨酸在哺乳期猪日粮中添加具有经济可行性,每头仔猪的销售价格应为8.30雷亚尔/kg。
