The metabolic status and reproductive performance of four pure breeds of beef cow (small size and low milk potential, Aberdeen Angus; small size and high milk potential, Welsh Black; large size and low milk potential, Charolais; and large size and high milk potential, Simmental) were monitored during their first two parities. Heifers from each breed were allocated to one of two levels of annual energy intake relative to metabolic body weight (M075) (mean daily intakes equivalent to 705 and 820 kj/kg M0·75) in a factorial design. In the 1st year 64 heifers (eight per treatment) which had calved as a consequence of first or second service were selected for the experiment. In the 2nd year 40 of these animals (five per treatment) which held to first or second service remained on experiment. Animals were housed all year round and given diets designed to represent energy intakes while grazing during the summer and conserved feeding during the winter. Pregnancy was established in late July of each year using a combination of oestrous synchronization and artificial insemination. Blood samples were collected at monthly intervals from weaning in November until calving in May; three times weekly from calving until oestrous synchronization (11 weeks later); and fortnightly thereafter until weaning.
For the annual levels of dietary energy intake offered, two breeds (Welsh Black and Charolais) exhibited relatively high growth rates and had the longest post-partum anovulatory periods; and Charolais cows also had the poorest conception rates of all breeds. Relatively lean cows at calving (body condition score < 2·5 units) were sensitive, in terms of the duration of the anovulatory period, to live-weight loss during the early post-partum period, particularly when blood glucose levels were low, whereas relatively fat cows at calving (body condition score > 2·5 units) were not. The data suggest: (i) that mechanisms controlling the anabolic processes governing maternal growth are antagonistic towards those that control reproduction; and (ii) the catabolism of lean tissue rather than fat tissue during the early post-partum period is also antagonistic towards the mechanisms that govern reproductive function in cows.

ABSTRACT.
Raspberry (Rubus idaeus) is an economically important crop, and its cultivation has expanded recently across temperate and subtropical regions of Brazil. There is no brazilian raspberry cultivar so far. Therefore, the indirect selection can be an useful tool to help during the breeding process. We evaluated linear and canonical correlations in primocane-fruiting raspberry cultivars in 2013 and 2014, in a completely randomized experimental design, with eight replications. The genotypes ?Alemãzinha?, ?Heritage? and ?Fallgold? were evaluated during two harvesting seasons, autumn and spring. Canonical groups were established among morphological (Group 1) and yield (Group 2) traits. In Group 1, plant yield and fruit weight were evaluated; in Group 2 the productive period, plant height, stem diameter, dry mass of pruning and plant leaf area were assessed. The linear and canonical correlations among morphological, phenological, and yield traits varied according to harvesting season. The phenological and morphological traits had greater linear correlation with yield traits in autumn than in spring. Based on our findings, to obtain more productive raspberry genotypes, plant leaf area and dry mass of pruning should be prioritized in the indirect selection. © FUNPEC-RP. |
