1. Do live or inactive yeasts improve cattle ruminal environment?
ABSTRACT This research was conducted to investigate the effect of live and inactive sugarcane yeast on beef cattle voluntary intake, apparent digestibility of nutrients, ruminal pH, volatile fatty acids (VFA) concentrations, and ruminal ammonia. Five rumen-cannulated Nellore heifers were distributed in a 5×5 Latin square design, with five experimental perio

2. Mineral mixtures from solid salt residues for lambs
The objective of this study was to evaluate water, mineral, feed and nutrient voluntary intakes, in addition to dry matter and nutrient digestibility and the nitrogen balance of lambs fed three mineral supplements. The first treatment consisted of solid salt residue (SSR) from an aquaculture tank; the second contained SSR from desalination waste; and the thi

3. Models for estimating feed intake in small ruminants
This review deals with the most relevant limits and developments of the modeling of intake of sheep and goats reared intensively and extensively. Because small ruminants are normally fed ad libitum, voluntary feed intake is crucial in feeding tactics and strategies aimed at optimal animal production. The effects of genetic, neuroendocrine, hormonal, feed and

4. Nutritive value of diets containing pods of faveira (Parkia platycephala Benth.) for confined finishing sheep
Performance and apparent digestibility were evaluated in sheep fed diets containing different amounts of faveira (Parkia platycephala) pods in replace to corn. Twenty crossbred Santa Inês lambs of approximately four months of age and average 21 kg were kept in individual stalls in randomized blocks and distributed according to weight. The following characte

5. Estimativa da excreção urinária de derivados de purinas a partir do consumo de NDT e determinação da contribuição endógena em bovinos de corte / Estimation of urinary excretion of purines derivatives from TDN intake and determination of the endogenous contribution in beef cattle
Two experiments were conducted with eight Nelore heifers (BW 267 17 kg ) to assess the excretion of purine derivatives (PD) from intake of TND, the intake and digestibilities of nutrients and the endogenous fraction of PD and nitrogen losses using the technique of fasting. In Exp.I the animal were fed a diet based on corn silage and concentrate in the propor

6. Qualidade da forragem do capim Pojuca em diferentes idades de rebrotação.
RESUMO: O estudo objetivou avaliar o consumo voluntário, a digestibilidade aparente e a composição química da forragem de Paspalum atratum capim Pojuca em diferentes idades de rebrotação. O experimento foi desenvolvido na Embrapa Cerrados, Planaltina - DF. A forragem foi cortada correspondendo a idade de rebrotação entre 22 e 28, 29 e 35, 36 e 42 e 4

7. Substitute of sugar cane silage + 0,5 urea (SCS) by pineapple stalk silage (PSS) on the feed ruminants / SUBSTITUIÇÃO DA SILAGEM DE CANA-DE-AÇÚCAR PELA SILAGEM DOS RESTOS CULTURAIS DO ABACAXIZEIRO NA ALIMENTAÇÃO DE RUMINANTES
The objective of this trial was to study the substitution of sugar cane silage + 0,5% urea (SCS) by the pineapple stalk silage (PSS) on the feed ruminants. The trial was done in Goiânia-GO and lasted 95 days. Five non castrated male lambs from Santa Inês breed were utilized, with an average age of eight months and live weight of 30,2kg 4,8kg. The experimen

8. Methodologies for modelling energy and amino acid responses in poultry
The objective of this paper is to present some of the issues faced by those whose interest is to predict responses in poultry, concentrating mainly on those related to the prediction of voluntary food intake, as this should be the basis of models designed to optimise both performance and feeding programmes. The value of models designed to predict growth or r

9. Silagem de cana-de-açúcar tratada com aditivo químico ou microbiano na alimentação de cabras em início de lactação / Sugar cane silage treated with microbial or chemical additives fed to goats in early lactation
Sugar cane is an important roughage source for ruminants. Sugar cane silage is an alternative feed which may improve operation efficiency at farm level. However, high levels of ethanol found in sugar cane ensiled without additive may reduce voluntary feed intake and may affect animal performance. Two experiments were performed to evaluate the effects of usin

10. Use of flavor, edulcorant and butyric acid in ration for lactating gilt / Uso de flavorizante, edulcorante e ácido butírico na ração de fêmeas suínas em lactação
A menor capacidade de consumo voluntário de alimentos das fêmeas atuais pode ser evidenciada na fase de lactação. As fêmeas são mais exigentes nutricionalmente, pois o consumo de ração durante o período de lactação pode se tornar insuficiente para atender às exigências de mantença e máxima produção de leite das porcas. Com isso, o consumo vo

11. Sugar cane silage for sheep and goats: nutritive value, performance and ingestive behavior / Silagem de cana-de-açúcar na alimentação de ovinos e caprinos: valor nutritivo, desempenho e comportamento ingestivo
Sugar cane ensiled without controlling ethanol production results in low quality roughage and may decrease voluntary feed intake and animal performance. Sugar cane silages nutritive value and their effects on performance and ingestive behavior of lactating goats and feedlot lambs were evaluated in different trials. Thirty-nine Saanen does were used to evalua

12. Effect of additives on feed quality and nutritional value of sugarcane silage. / Qualidade da silagem de cana-de-aÃÃcar elaborada com diferentes aditivos.
The objective of this research was to evaluate the effects of the use of additives on the quality and nutritional value of the sugarcane silage. Sugarcane variety RB-72454, at 18 months of regrowth, was stored for 180 days in experimental concrete silos (500 kg capacity). Treatments were expressed by additives amounts added to sugarcane silage at ensiling (b
