| The objective of this study was to evaluate the biomarkers of the redox state of pre-weaned Jersey dairy calves that consumed milk from cows supplemented with green tea (Camellia sinensis) or oregano extracts (Origanum vulgare). A completely randomized design was used with repeated measures in time. From their birth to 60 days of life, 8, 8 and 7 calves received milk from cows fed on a basal diet without addition of plant extracts (CON), with addition of 10.0 g of oregano extract (OE) per day and with 5.0 g of green tea extract (GT) per day, respectively. On days 1, 30, and 60 after birth redox state biomarkers were evaluated. Body weight was eval-uated every two weeks, rectal temperature and fecal score were accessed every two days and concentrate intake... |

| The aim of this study was to evaluate the effects of green tea (Camellia sinensis) and oregano (Origanum vulgare) extracts on behavior, weight gain, and health indicators of dairy calves from birth to 60 days of age. Twenty-one Jersey calves were distributed into three treatments: without additives (CON); green tea extract (GT): supply of 30 mg/kg of body weight/day; and oregano extract (OR): supply of 60 mg/kg of body weight/day. Observers registered animal?s behavior at 5-minute intervals from 8:00 to 16:00, three times a week, from day 1 to day 60 of life. The behavioral variables considered were time spent in standing, lying down, ruminating, frequency of visits to feeders, frequency of eating pasture and straw, as well as body weight gain, body... |

| Bos taurus taurus and Bos taurus indicus cattle subspecies present different capabilities in coping with situations of elevated temperatures, the latter being more tolerant to heat stress. Thus, some breeding programs crossed these subspecies to produce a high producing yet heat-tolerant breed (Girolando). Nineteen Holstein (H100) and 19 Girolando cows [(½ Holstein × Gir (H50) and ¾ Holstein × Gir (H75)] with similar milk production were used in a six-day experiment to evaluate the consequences of heat stress due to shade deprivation on their physiological, blood and milk traits. Cows were exposed to a non-shaded environment between morning (06:00h; GMT -3:00) and evening milking (14:30h; GMT -3:00) with access to water ad libitum. Procedures were... |

| O objetivo desse trabalho é apresentar os principais resultados de pesquisa sobre o leite instável não ácido ou LINA. A proporção de amostras de leite com estabilidade térmica abaixo do mínimo exigido pela indústria configura em um sério problema, com uma ocorrência mais elevada durante os períodos de carência alimentar. Trata-se um problema multifatorial cujos fatores intervenientes são relacionados à execução do teste (concentração do álcool), manejo (alimentação, clima, relação homem-animal), ao animal (suscetibilidade ao estresse, potencial produtivo, estádio da lactação, sanidade, problemas digestivos e metabólicos, frações da caseína), entre outros. Existem dúvidas quanto à capacidade do teste do álcool em estimar a estabilidade térmica do leite. A... |

| The objective of this work was to evaluate the inclusion of sodium citrate and sodium bicarbonate in the diet of lactating Jersey cows, and its effects on the metabolic attributes, productivity and stability of milk. We evaluated urinary pH, levels of glucose and urea in blood, body weight, body condition score, milk yield, milk stability (ethanol test), and milk physicochemical properties of 17 cows fed diets containing sodium citrate (100 g per cow per day), sodium bicarbonate (40 g per cow per day) or no additives. Assessments were made at the 28th and 44th days. Supply of sodium citrate or bicarbonate has no influence on the metabolic attributes, productivity, body weight, and body condition score of the cows, neither on the composition and stability... |
