Comparison of maternal breeds in reciprocal crosses in F1 heifers production used in milk production systems Dairy cattle breeds of European origin stand out for their high productive and reproductive efficiency in temperate climates, but they usually do not present this efficiency in tropical climate, in conditions such as high temperature and humidity, high incidence of endo and ectoparasites and low level of management. On the contrary, Zebu breeds in selection programs to increase milk production are naturally adapted to such conditions, that is, they produce well in less sophisticated managerial p Status: Completed Start date: Mon Oct 01 00:00:00 GMT-03:00 2007
Influence of ploymorphisms in the gene encoding the Stearoyl-CoA desaturase (SCD) enzyme on the nutritional quality of milk fat in Gyr and Guzerat cows Recent evidence from observational studies and controlled clinical trials indicates that milk fat, although predominantly saturated, has neutral or positive effects on cardiometabolic health. Such benefits have been attributed to the complex and unique chemical nature of milk fat, which contains several compounds potentially beneficial to health, such as butyric acid (C4:0), vaccenic acid ( trans-11 C18:1), rumenic acid ( cis--9, trans-11 CLA), oleic acid ( cis-9 C18 ...

Genomic selection in dairy cattle breeds in Brazil raditional breeding has generated significant genetic gain over time. However, this strategy falls short of yielding information on the biological processes involved. Additionally, there are great difficulties for the genetic improvement of characteristics which are measured solely in one gender and/or late in the life span of the animal. With the development of DNA chips it became possible maximizing genetic gain by reducing the generation interval and increasing the intensity of selection.

Aquaculture species' nutrition This project aims to study nutritional factors and establish new types of diets for tilapia ( Oreochromis niloticus), pintado ( Pseudoplatystoma corruscans), tambaqui ( Colossoma macropomum) and marine shrimp ( Litopenaeus vannamei.), species inserted into production chains still incipient in Brazil. Due to the differentiated state of each species, studies were conducted in oreder to fill the nutritional gaps in key technological areas in which each species had greate ...
