Este trabalho foi desenvolvido na exploração suinícola de Malaqueijo, pertencente
à empresa SuiniTejo, Lda, entre os meses de abril e maio de 2024. O principal objetivo
consistiu em avaliar o efeito da suplementação alimentar de porcas, na fase pré-parto, e
de leitões em aleitamento, sobre o desempenho produtivo dos animais até ao desmame.
Na primeira fase do estudo, 78 porcas foram distribuídas por dois grupos: um
grupo controlo, sem suplementação, e um grupo experimental, suplementado com um
alimento composto complementar (Vitonic CH®) administrado durante os quatro dias
anteriores à data prevista para o parto. Foram recolhidos dados relativos ao peso ao nascimento dos leitões, prolificidade, taxa de mortalidade em aleitamento e ganho médio
diário (GMD). Os resultados demonstraram que a suplementação não teve impacto estatisticamente significativo nos parâmetros avaliados, embora se tenham observado tendências favoráveis em alguns indicadores produtivos nas porcas suplementadas.
Na segunda fase, avaliou-se o efeito da introdução de um alimento completo inicial modular da flora intestinal (SuperFlor®) fornecido aos leitões durante a lactação,
comparando-se com a alimentação convencional da exploração. Foram pesados 956 leitões entre o 4.º e o 5.º dia de vida, e novamente ao 28.º dia, altura do desmame, totalizando
921 leitões com registos completos. A análise centrou-se na evolução do GMD e no peso
ao desmame. Tal como na fase anterior, não se verificaram diferenças estatisticamente
significativas entre os grupos.
De forma global, os resultados obtidos sugerem que, nas condições específicas
deste estudo, a suplementação com Vitonic CH® e SuperFlor® não promoveu efeitos
significativos no desempenho produtivo até ao desmame. Contudo, a tendência positiva
observada em alguns indicadores justifica a realização de estudos complementares com
maior dimensão amostral, maior controlo do consumo e maior duração da suplementação,
de forma a aprofundar o conhecimento sobre o real impacto destas estratégias nutricionais
na eficiência da produção suinícola.
This study was conducted at the pig farming facility in Malaqueijo, owned by SuiniTejo, Lda, between April and May 2024. The main objective was to evaluate the effects of dietary supplementation of sows in the pre-farrowing phase and suckling piglets on productive performance up to weaning. In the first phase of the study, 78 sows were allocated into two groups: a control group without supplementation and an experimental group supplemented with a complementary compound feed (Vitonic CH®), administered during the four days prior to the expected farrowing date. Data were collected on piglet birth weight, litter size, pre-weaning mortality rate, and average daily gain (ADG). The results showed no statistically significant differences in the parameters evaluated. However, favorable trends were observed in some performance indicators among the supplemented sows. In the second phase, the effect of introducing a complete early feed designed to modulate gut microbiota (SuperFlor®) was assessed during lactation, in comparison with the farm’s conventional feeding protocol. A total of 956 piglets were weighed between the 4th and 5th day of life, and again on day 28, at weaning, resulting in 921 piglets with complete data. The analysis focused on the evolution of ADG and weaning weight. As in the first phase, no statistically significant differences were observed between groups. Overall, the results suggest that, under the specific conditions of this study, supplementation with Vitonic CH® and SuperFlor® did not produce significant effects on piglet performance up to weaning. Nevertheless, the positive trends observed in some indicators warrant further research with larger sample sizes, tighter control over intake, and longer supplementation periods to better understand the true impact of these nutritional strategies on swine production efficiency.
