| O objetivo do presente estudo foi o de avaliar o efeito da somatotrofina bovina recombinante (BSTr) sobre a taxa de ovulação após a indução, sobre o metabolismo intermediário do colesterol e da glicose em ovelhas, e no o ganho de peso de cordeiros lactentes cujas mães foram tratadas com BSTr bem como as variações do peso e escore corporal das mesmas. Utilizou-se para tanto 3mg/kg de BSTr em formulação de liberação prolongada em dose única para o primeiro experimento e, 4mg/kg para o segundo. No primeiro experimento, os resultados obtidos mostraram que a incidência de estro foi de 100% nos grupos controle e tratado, onde o número de corpos lúteos encontrados foi de 0,9 ± 0,18 no grupo controle e 1,18 ± 0,12 no grupo tratado, não sendo diferentes... |

| ABSTRACT The present study evaluated the effect of variation in the amount of total dietary fiber (TDF) in sow diets, provided from 74 to 114 days of gestation, on the digestibility of nutrients and energy during gestation, as well as productivity and metabolism during gestation and lactation. Thirty-three sows were used in a randomized experimental design. The amounts of TDF in three treatment diets were 156, 223, and 282 g kg−1. The daily intake of nutrients and energy was similar for all diets the entire period of gestation, differing only in the volume of ration consumed, which was 2.1, 2.2, and 2.4 kg day−1 (days 74 to 90) and 2.5, 2.6, and 2.8 kg day−1 (days 91 to 111) for the 156, 223, and 282 g kg−1 TDF diets, respectively. During gestation, the... |

| Los rumiantes alimentados con forrajes de elevado contenido de proteína rápidamente degradable en el rumen o suplementados con nitrógeno no proteínico, absorben cantidades sustanciales de amonio en el rumen y muy poca glucosa en el intestino, en circunstancias que requieren mantener una adecuada capacidad ureagénica y gluconeogénesis para sostener su eficiencia productiva. En esta condición se eleva la producción de amonio ruminal, el cual se absorbe y posteriormente se metaboliza por el hígado en urea. Las elevadas concentraciones de amonio en el rumen pueden sobrepasar la capacidad hepática de sintetizar urea, lo que provoca una sobrecarga en el ciclo de la urea y demanda una excesiva cantidad de α-cetoglutarato y oxalacetato para la formación de... |

| ABSTRACT: Worldwide, milk analysis is an satisfactory measurement of milk quality on dairy farms. Milk composition is the base for payment systems, so knowledge of its characteristics at different periods is essential for modern dairy producer. The aim of the study was to evaluate the effects of year, season, stage of lactation, and lactation number on variations in milk yield and composition of Holstein cows (n=148,604). Milk yield estimated by multiple regression was 25,50L/cow/day. Winter was the season with the highest milk yield and the highest protein and lactose content. Milk fat was highest in the fall, in cows in late lactation and also in primiparous cows. Lactating cows from 6 to 60 days in lactation and those in 2nd or 3rd lactation showed the... |

| ABSTRACT: This study vised to detect possible changes in chemical and cellular composition of cow’s milk at different milking sessions and to test if proportional or composite milk sampling can be used instead of separate milk analysis. Two experiments were conducted: one in cows milked thrice daily and the other one in cows milked twice daily. In both experiments, three milk samples were collected from each cow in each milking session in order to determine milk composition at each milking; to have a composite sample, i.e., a single sample from the same aliquots of milk from each milking session; and to have a proportional sample, i.e., a single sample from each milking session in a volume proportional to milk volume yielded. Fat content and fat to... |
