EFFECTIVENESS OF THE APPLICATION OF OPTIONS FOR PRE-START FEEDING OF PIGLETS

Abstract

The research presented in this work is aimed at testing the influence of various types of pre-start feed on the growth, development and preservation of piglets in the nursery and post-weaning periods. The main boundary factor in growing piglets is the natural biological boundary of the lactation productivity of sows, which leads to a shortage of live milk in siblings and the need for early introduction of supplementary feed. The method of work is to assess the effectiveness of various prestarter feeds in one-year-old piglets and analyze their impact on productivity indicators. Research methods included experimental assessment of growth performance of piglets, saving rate, milk production of sows and feed efficiency. The investigation was carried out by the government on the basis of a scientific-government experiment, in which 12 sows and their offspring were tested. The piglets were divided into three groups, the skin of which received different options of pre-start feed: TM Best Mix 8393, Laktofit-Porco 1 (light) and Laktofit-Porco 2 (dark). The average weight gain, live weight of piglets at 35, 60 and 100 days, as well as the rate of their saving were analyzed. The results showed that until the 21st day, no statistically significant differences between the groups were recorded. However, the piglets that received Lactofit-Porco 1 showed better indicators of life expectancy, comparable to other groups. At the same time, piglets that were fed Lactofit-Porco 2 had slightly lower average growth rates. The highest indicators of productivity were recorded in the group that fed Best Mix 8393, the fragments of this compound feed better satisfied the consumption of piglets in older piglets after a decrease in the supply of milk from the mother. Until the 60th day of age, piglets from the first group have a low live weight of 4-6% equal to that of other groups, and their average weight gain remained consistently high. The discussed results indicate that the use of high-quality compound feeds allows minimizing feed stress in piglets after weaning, which has a positive impact on their growth and savings. Piglets that have been fed the Best Mix 8393 pre-starter are less susceptible to feed stress, adapting better to changing the diet and finding more effective feed intake. Recently, a cost-effective analysis demonstrated that the use of mixed feed from local breeding was less effective, resulting in additional costs of 2.08–2.35 mental units ($) per pig after separation from the world of five years. Thus, the results of the study confirm that clear pre-starter feed is an important factor in ensuring optimal growth of piglets and increasing the economic efficiency of pig farming. The use of pre-starter feeds, divided according to current technological standards, allows for the preservation of piglets, promotes their rapid adaptation and minimizes the negative effects of technological stress. The findings may be useful for the development of effective strategies for yearling piglets in industry minds.
