Este trabalho foi realizado no Departamento de Biologia, Setor de Fisiologia Vegetal da Universidade Federal de Lavras, no periodo de fevereiro a julho de 1999. O Paspalum paniculatum esta entre as especies que melhor se adaptam as areas sujeitas a inundacao temporaria. Entretanto, sao poucos os estudos relacionados a producao de sementes e sua conservacao, visto que a principal via de reproducao desta especie ocorre via sexuada. O objetivo deste trabalho foi avaliar as possiveis alteracoes na germinacao e nos costituintes de reserva das sementes de Paspalum paniculatum ao longo de um periodo de armazenamento. para isto, foram utilizados tres tipos de embalagens: vidro, sacos plasticos e sacos de papel. Os tratamentos tecnicos foram temperatura ambiente e camara fria (10 C, U. R. 40 %). Os tempos de armazenamento foram: 0, 30, 60, e 90 dias. As analises realizadas em cada tratamento foram: grau de unidade das sementes, percentual de germinacao, proteinas, Aminoacidos, acucares redutores, acucares soluveis totais e amido. Os teores de aguaa (11%) e o percentual de germinacao (80%) mantiveram-se constantes em todos os tratamentos realizados. As poucas alteracoes nos constituintes de reverva nao foram determinantes no processo de deterioracao das sementes. Os resultados obtidos demonstram que as sementes de Paspalum paniculatum mantiveram a sua qualidade fisiologica em todo o periodo de armazenamento, independente das condicoes em que as mesma foram submetidas. |

Diarrhea and respiratory diseases pose significant challenges in the rearing of pre-weaned calves, motivating the investigation of tools to improve gastrointestinal tract development, health, and overall performance in young calves. Consequently, the primary objective of this study was to assess the effectiveness of an additive incorporated into milk replacer to promote the development and health of the animals. Forty-six dairy calves were randomly assigned into two treatments: control (CON, n = 23; with 15 females and 8 males), and sodium butyrate (SB, n = 23; with 15 females and 8 males). The calves in the SB treatment group were supplemented with 4 g/d of unprotected sodium butyrate (Adimix, Adisseo, China), added to the milk replacer from 4 to 60 days of age. Water and starter were fed ad libitum. The study evaluated several parameters, including feed intake, nutrient digestibility, ruminal pH, ammonia and volatile fatty acids, blood metabolites (glucose, insulin-like growth factor type 1, urea, β–hydroxybutyrate), hemogram, health scores, performance, and feed efficiency. Bull calves were euthanized at 60 days of age for organ comparison, while heifer calves were assessed for carryover effects up to 90 days of age. Data were analyzed independently using linear mixed models using the nlme package in R, and the Artools package for non-parametric categorical outcomes. Although the feed intake and performance variables exhibited differences within weeks, no divergence was observed between treatment groups. Notably, a positive treatment-by-week interaction was identified for starter feed intake (p = 0.02) and total dry matter intake (p = 0.04) during pre-weaning for CON animals. Ruminal parameters, blood metabolites, and hemogram values such as glucose, urea, insulin-like growth factor type 1, mean corpuscular value, lymphocytes, and neutrophils displayed differences within weeks during the pre-weaning stage, but similar results within groups. No differences between supplemented and non-supplemented calves were found across nutrient digestibility, organ development, and histology. Regarding health scores, differences were noted within weeks for fecal and respiratory scores during the pre-weaning stage, and only the respiratory score during the post-weaning stage. Consequently, butyrate supplementation did not elicit improvements or negative effects in the body development or health status of dairy calves.
