Internal Temperature of Girolando (Holstein×Gir) heifers in integrated crop, livestock (ICLS) and forestry (ICLFS) systems.

The objective of this work was to evaluate the internal temperature (IT) of Girolando heifers in integrated crop, livestock (ICLS) and forestry (ICLFS) systems. Trial was carried out at experimental field of Embrapa Rondônia, Porto Velho, Rondônia, Brazil

Characterization of the daily behavior of grazing Girolando heifers in integrated livestock systems.

Tree shade in pasture system should be an alternative to reduce the impact of warm climate and heat stress on dairy cattle herd. This study aimed to access grazing behavior of Girolando heifers in integrated crop, livestock (ICLS) and forestry (ICLFS) systems throughout a 24-hour day

Inbreeding depression of 28 maize elite open pollinated varieties.

The study of inbreeding depression is important for breeding strategies such as use of inbred progenies or extraction of inbreed lines. A diallel of 28 maize open-pollinated varieties was evaluated in 10 environments in the early 1990s. At the same time, S1 populations for each of the 28 varieties were evaluated in the same 10 experiments (environments). Yield reductions of the populations from S0 to S1 (mean of the 10 environments), varied from 34.6% (CMS-01) to 59.2% (CMS-30), with an average of 49.1%. Inbreeding depression was greater in populations with a wider genetic base, which had never been exposed to inbreeding (CMS-30, BR-107, PH4, Cunha, Saracura, Nitrodent, and Nitroflint). Inbred lines with greater yield means should be obtained from the BR-105, BR-111, CMS-01, CMS-03, BR-106, CMS-14c, and CMS-28 populations. The use of parameter estimates generated by analysis of inbreeding depression, allow to make inferences about frequencies of deleterious alleles in the population. The frequencies of favorable alleles in the parents can be obtained by diallel analysis. The association of these two types of information, can provide a better interpretation of the genetic parameters and also can improve the process of selection of parents for either an intra- or an inter-populational breeding program
