1. Passive immune transfer, health, pre-weaning performance, and metabolism of dairy calves fed a colostrum supplement associated with medium-quality maternal colostrum
ABSTRACT The objective of this study was to evaluate passive immunity transfer, health, performance, and metabolism of Holstein calves fed colostrum supplement associated with medium-quality colostrum. After birth, calves were blocked according to birth weight and date and distributed into the following treatments: high-quality colostrum (> 50 mg of Ig/mL; n

2. Evaluation of mannan-oligosaccharides offered in milk replacers or calf starters and their effect on performance and rumen development of dairy calves
The objective of this study was to evaluate the route of administration of mannan-oligosaccharides in the diet of dairy calves and their effects on performance and plasma parameters indicative of rumen development. Following birth, twenty-four male Holstein calves were used in a completely randomized design and assigned to the following treatments: Control;

3. Silagem de colostro: caracterização do perfil de fermentação anaeróbia e desempenho de bezerros leiteiros / Colostrum silage: dynamics of anaerobic fermentation and dairy calves performance evaluation
The objective of this study was to characterize the fermentative dynamic of bovine colostrum, under anaerobic condition, and determine the nutritional value, as well as evaluate dairy calves´ performance receiving colostrum silage as liquid diet. In the first experiment, bovine colostrum from second and third milking was fermented at room temperature in PET

4. Effects of extensive system versus semi-intensive and intensive systems on growth and carcass quality of dairy kids
The aim of this research was to study the effects of three different management systems on growth and carcass quality of 61 Murciano-Granadina breed kids and their interaction with sex. In the extensive system, 21 kids were allocated to suckle from their dams on free-range pasture with no additional feedstuff. In the semi-intensive system, 20 kids were suckl

5. Desempenho e desenvolvimento ruminal de bezerros em sistema de desaleitamento precoce recebendo aditivos alternativos aos antibióticos / Performance and rumen development of calves under early weaning program receiving alternative additives to replace antibiotics
Two studies were conducted to evaluate alternative additives to replace antibiotics on dairy calves production under early-weaning program. On the first trial, the addition of mannanoligosaccharides (MOS) in the diet of dairy calves on performance and plasma parameters indicative of rumen development, as well as the route of administration, milk replacer or

6. Estudo da flutuação sérica de anticorpos maternos nos períodos pré e pós-parto e transferência de imunidade passiva em cabritos recém-nascidos utilizando colostro bovino e caprino / Study of maternal serum antibodies fluctuation in pre and post partum period and passive immunity transfer in newborn goat kids using bovine and caprine colostrum
The objective of this study was to evaluate the fluctuation of serum antibodies in goats pre and immediately post partum period and the passive immunity acquisition efficiency in goat kids fed caprine and bovine colostrum, contributing for an evaluation of colostrum management alternative and a better knowledge of passive immunity formation and transference

7. Desempenho e desenvolvimento dos ÃrgÃos digestivos de cordeiros santa inÃs, alimentados com dietas contendo diferentes nÃveis de fibra / Performance and development of the digestive tract of Santa InÃs lambs fed with diets containing different levels of fiber.
This study was carried out at the Ovine Production Sector of the Federal University of Lavras-MG, to evaluate the effects of different levels of forage neutral detergent fiber on the consumption, digestibility, feed conversion, weight gain and development of the digestive tract of Santa InÃs lambs in four different development phases. The suckling phase (up

8. Ontogenic development of lamb intestinal sodium-glucose co-transporter is regulated by diet.
1. The ontogenic development of the intestinal Na(+)-glucose co-transporter was measured in lambs as a function of diet. Transport activity was assayed in brush-border membrane vesicles and the expression of transport protein in the brush-border membrane determined by Western analysis. 2. Na(+)-dependent D-glucose transport increased to a maximum (300-700 pm

9. Efficacy of halofuginone lactate against Cryptosporidium parvum in calves.
The efficacy of halofuginone lactate against natural Cryptosporidium parvum infection in 150 neonatal market calves of a mixed Belgian breed was tested. The drug was administered orally in the milk replacer over a period of 3 to 14 days at doses ranging from 30 to 500 micrograms/kg of body weight. Over a period of 4 weeks, the animals were examined twice a w
