“…These factors increase intestinal absorption and renal reabsorption of phosphate as a result of an increased bone development rate (6) . Such findings are similar to those of other studies which claim that serum iP concentrations are inversely proportional to increasing age (17) . Nonetheless, other researchers disagree with this assertion and state that iP concentration is directly related to age (19) .…”

This study aimed to evaluate the effects of animal age and sex on serum concentrations of proteins, metabolites, minerals, and enzymes in Bonsmara cattle up to two years of age. Blood samples were collected from 179 animals (92 males and 87 females), aged between 15 days and 24 months. The animals were divided into four age groups: G1: 15 days ┤2 months, G2: 2 ┤6 months, G3: 6 ┤ 12 months, and G4: 12 ┤24 months of age. The samples were processed in an automatic multichannel analyzer using Labtest Diagnóstica™ kits. Animal age had a significant influence on most of the serum biochemical constituents except for magnesium (Mg) and the Ca+:iP ratio. As age increased, G3 showed the highest concentrations of total proteins (TP), globulins (Glob), urea, and cholesterol (Chol); while G4 had a gradual increase and higher values of creatinine (Crea), aspartate aminotransferase (AST), and alanine aminotransferase (ALT). Conversely, albumin:globulin (A:G) ratio, calcium (Ca+), inorganic phosphorus (iP), alkaline phosphatase (ALP), and gamma-glutamyltransferase (GGT) decreased from G1 to G4. Moreover, animal sex influenced serum values of albumin (ALB), Glob, A:G ratio, Crea, urea, triglycerides (TRI), Ca+, iP, Ca+:iP ratio and Mg. In conclusion, the factors of age group and sex significantly influenced the concentrations of serum biochemical constituents in Bonsmara cattle in the growth phase.

“…It should be considered that in addition to milk being rich in Ca + , young animals have a greater capacity to absorb and use calcium. As it is known, this mineral is highly required due to its need for bone growth (3,16) , results that corroborate those of other researchers (17) .…”

“…O menor valor apresentado pelo Pi sérico nos animais mais velhos (G4) em relação ao do G1 e G3, demonstrando comportamento inversamente proporcional ao aumento da idade, pode ser atribuído a maior disponibilidade deste mineral no leite (18) , e ao hormônio de crescimento, o qual possui alta atividade em animais jovens, promovendo a absorção intestinal e a reabsorção renal de fosfato em decorrência da alta taxa de desenvolvimento ósseo (6) . Esses resultados são similares aos de outros estudos, que observaram relação das concentrações séricas do Pi com a idade, e comportamento inversamente proporcional ao aumento da idade (17) . Entretanto, discordam de outros pesquisadores que não relataram relação dos valores séricos do mineral com a idade dos animais (19) .…”

Resumo Objetivou-se avaliar a infuência da idade e sexo nas concentrações séricas de proteínas, metabólitos, minerais e enzimas em bovinos da raça Bonsmara com até dois anos de idade. Foram colhidas amostras de sangue de 179 animais (92 machos e 87 fêmeas), de 15 dias a 24 meses de idade, distribuídos em quatro grupos etários: G1: 15 dias ┤2 meses, G2: 2 ┤6 meses, G3: 6 ┤12 meses e G4: 12 ┤24 meses de idade. As amostras foram processadas em analisador automático multicanal, utilizando kits da Labtest Diagnóstica®. A variável idade dos animais influenciou significativamente nos valores da maioria dos constituintes bioquímicos séricos avaliados, exceto no magnésio (Mg) e na relação Ca+:Pi. O aumento da idade culminou com a maior concentração das proteínas totais (PT), globulinas (Glob), ureia e colesterol (COL) no G3; aumento gradual e maior valor de creatinina (Crea), aspartato aminotransferase (AST) e alanina aminotransferase (ALT) no G4. Em contrapartida, houve diminuição da relação albumina:globulina (A:G), cálcio (Ca+), fósforo inorgânico (Pi), fosfatase alcalina (FAL) e gama glutamiltransferase (GGT) do G1 ao G4. O fator sexo influenciou nos valores séricos da albumina (ALB), Glob, relação A:G, Crea, ureia, triglicérides (TRI), Ca+, Pi, relação Ca+:Pi e Mg. Conclui-se que o fator idade e sexo influenciaram significativamente nos valores dos constituintes bioquímicos séricos analisados de bovinos da raça Bonsmara em fase de crescimento.

The primary objective of this study was to evaluate the effects of liquid (F-LAB) and commercial (C-LAB) probiotics sourced from Rye-Grass Lactic Acid Bacteria on broiler chickens experiencing heat stress (HS). The research involved 240 broiler chicks divided into six groups: control, F-LAB, C-LAB (raised at 24°C), HS, F-LAB/HS, and C-LAB/HS (exposed to 5–7 hours of 34–36°C daily). While F-LAB and HS/F-LAB groups received a natural probiotic added to their drinking water at a rate of 0.5 ml/L, C-LAB and HS/C-LAB groups were supplemented with a commercial probiotic at the same dosage. No probiotic supplementation was administered to the control and HS groups. The results revealed that without probiotic supplementation, heat stress led to a decrease in body weight gain, T3 levels, citrulline, and growth hormone levels, along with an increase in the feed conversion ratio, serum corticosterone, HSP70, ALT, AST, and leptin levels. Heat stress also adversely affected cecal microbiota, reducing lactic acid bacteria (LABC) while increasing Escherichia coli and coliform bacteria (CBC) counts. However, in the groups receiving probiotic supplementation under heat stress (F-LAB/HS and C-LAB/HS), these effects were alleviated. Particularly noteworthy was the observation that broiler chickens supplemented with natural lactic acid bacteria (F-LAB) exhibited greater resilience to heat stress compared to those receiving the commercial probiotic, as evidenced by improvements in growth, liver function, hormonal balance, intestinal health, and cecal microbiome ecology. These findings suggest that the supplementation of naturally sourced probiotics (F-LAB) may positively impact the intestinal health of broiler chickens exposed to heat stress, potentially supporting growth and health parameters.
