• Abstract

  In the Us and Brazil, consolidation of large numbers of animals into small land areas to improve the efficiency of meat and milk production may contribute to environmental problems unless animals are fed and managed properly. Any animal operation that does not have proper nutrition, feeding, management and waste-disposal program has the potential to pollute the environment. Several resear…

• Abstract

  The determination of body mass of an animal is extremely important as indicative of development; however this measurement is influenced by the gastrointestinal content. This could be avoided by the use of empty body mass. Since the empty body mass determination involves the slaughter of the animal, and many times strategic decisions are made for live animals, it is desirable to have a way…

  Relationship between body weight and empty body weight in growing goats, BP.IC

• Abstract

  In ruminants, the digestion of food and nutrients depends on several factors such as the fractional rate of fermentation (kd), the fractional rate of passage (kp), enzymatic hidrolysis of digesta and possible fermentation in the large intestine. Passage rate has great influence on particle retention in the rumen, moreover, has relation with potential dry matter intake (DMI), amount of und…

• Abstract

  The world goat herd has increased more compared to other livestock species mainly due to ease of adaptation of the goat to different environments. Thus, the nutritional requirements of these animals change according to the environment to which they are, in addition, other physiological factors can affect their nutritional requirements , such as gender, breed and reproductive stage. In th…

• Abstract

  The ability to manipulate milk fat synthesis has been of paramount importance to dairy farmers as milk fat content needs to meet the expectations of consumers and it affects profitability. Milk fat responses have been observed when dairy cows are supplemented with amino acids; however the mechanism of this phenomenon is still unclear. It has been demonstrated that amino acids play an impo…

  LINKING AMINO ACIDS TO MILK FAT SYNTHESIS REGULATION, BE.PQ

• Abstract

  Models are important tool to understand the nutrition and growth of goats enabling the manager in the decision-making. In this context, the use of system dynamic approach would help researchers to stare complex issue, such as intake regulation, with a holistic view. The voluntary dry matter intake (DMI) intake is under control of long-term signals (e.g., lypostatic theory) integrated with…

  A dynamic model to predict dry matter intake associated with fat and protein fluxes in growing goats, BE.EP.PD

• Abstract

  Gestation is an important phase in the life of an animal, as the transformations that take place affect not only the reproductive system, but also the whole organism of the pregnant animal. Inadequate nutrition of the female in this phase can impair the growth of the offspring. There is a lack of information in current feeding systems regarding the nutritional demands of pregnant goats. T…
