Revista Brasileira de Zootecnia , 2003,
Abstract: O objetivo deste estudo foi avaliar o consumo, produ o e composi o do leite, digestibilidade dos nutrientes e eficiência alimentar de vacas mesti as de baixo potencial de produ o, alimentadas com dietas à base de cana-de-a úcar. Foram utilizadas oito vacas mesti as ]! Holandês/Gir com peso vivo médio de 425 kg, após o ter o inicial de lacta o. Os animais foram distribuídos em dois quadrados latinos (4x4), de acordo com a ordem de lacta o e alimentadas com dietas completas à base de cana-de-a úcar, sendo, cana mais uréia (CAU); cana, uréia e farelo de algod o (CFA); cana, uréia e milho (CMM); cana, uréia e farelo de trigo (CFT). Os consumos de matéria seca (MS), fibra em detergente ácido (FDA), fibra em detergente neutro (FDN) e matéria organica (MO) foram superiores para as dietas com farelo de algod o e trigo. O consumo PB foi maior para o CFA em rela o ao CAU. Os consumos de carboidratos totais (CHT), carboidratos n o-fibrosos (CNF) e NDT apresentaram o mesmo comportamento, sendo superior para CFT e CFA em rela o ao CAU. Os coeficientes de digestibilidade da MS e MO foram maiores para a suplementa o com milho, porém a digestibilidade da PB foi superior para o CFA, em rela o aos demais. Os coeficientes de digestibilidade da FDN e CHT foram maiores para o CMM em rela o ao CFA. Porém, o coeficiente de digestibilidade da FDA foi inferior para o CFA. O teor de NDT foi superior para CMM e CAU em rela o aos outros tratamentos, variando de 88,25 a 74,44%. A produ o de leite com corre o para 4,0% de gordura foi inferior para CAU comparada aos demais tratamentos. N o houve altera o nos teores de proteína e gordura do leite. No entanto, o CAU proporcionou as menores produ es de proteína e gordura do leite. O CFA apresentou a menor eficiência alimentar.

Revista Brasileira de Zootecnia , 2010, DOI: 10.1590/S1516-35982010001200027
Abstract: the aim of this study was to evaluate the effect of the manner in which diet is supplied and spineless cactus forage is processed on intake, nutrient digestibility, milk production and composition, concentration of plasma urea nitrogen (pun) in the milk urea nitrogen (mun) and production of microbial protein in holstein cows in lactation. eight cows (453 ± 75.8 kg) yielding 14 kg milk/day were allotted to a factorial design, with two manners of cactus processing (knife-chopped or forage machine) and two diet supplies (separate concentrate or total mixed ration). intakes of dry matter, organic matter, neutral detergent fiber and total digestible nutrients were lower when cactus was knife-chopped. digestibility, milk production and fat and protein yield did not change according to the manner diet was supplied neither by forage cactus processing. average milk production was 14.8 kg/day for knife-chopped cactus and 14.6 kg/day for cactus chopped in forage machine and 14.8 kg/day when cactus was given in separate concentrate and 14.5 kg/day when it was given in total mixed ration. however, fat content was lower (36 g/kg) for knife-chopped cactus fed cows. purine derivatives and concentrations of n-ureic were not influenced by the manner in which diet was supplied neither by the forage cactus processing. means observed for efficiency of microbial protein synthesis (98.9 g/kg tdn), pun concentrations (21.3 mg/dl) and mun (18.2 mg/dl) were similar for cactus processing and for the manner in which diet was supplied. forage-machine cactus processing improves dry matter intake and total mixed ration supply avoids selectivity.

Teocomunica??o , 2006,
Abstract: Na miss o da Igreja, como continuadora da obra salvífica de Cristo, está a reconcilia o sacramental misericordiosa, que, ressaltando o mistério pascal como ponto máximo da revela o e atua o da misericórdia divina, expressa toda a sua eclesialidade quando vivenciada e celebrada com a comunidade eclesial. Essa forma celebrativa ressalta a importancia e o papel da comunidade crist na reconcilia o dos crist os e a sua responsabilidade de proporcionar-lhes a experiência da rela o entre a eclesialidade e a misericórdia na segunda forma deste sacramento. In the mission of the Church, as continuing the salvation work of Christ, it is the merciful sacramental reconciliation, that, emphasizing the paschal mystery as maximum point of the revelation and performance of the divine mercy, expresses all its ecclesiality when lived deeply and celebrated with the ecclesial community. Such a celebration emphasizes the importance and the role of the Christian community in the reconciliation of the Christians and its responsibility to provide to them experience of the relation between the ecclesiality and the mercy in the second form of this sacrament.
