1. Effects of long-term controlled internal drug release reuse on reproductive performance, hormone profiles, and economic profit of sheep
ABSTRACT Fifty-seven multiparous Awassi ewes in the breeding season were used to compare the effects of controlled internal drug release (CIDR) reuse on hormone profiles, reproductive performance, and economic production. Ewes were randomly allotted to one of three CIDR treatments: new (control), once-used, and twice-used; treatment lasted 12 days. Blood sam

2. GENETIC GAINS IN THE POPCORN POPULATION UENF-14: DEVELOPING THE NINTH GENERATION OF INTRAPOPULATION RECURRENT SELECTION
RESUMO A ocorrência da correlação negativa entre produtividade de grãos (PG) e capacidade de expansão (CE) no milho-pipoca contribui para dificultar o processo seletivo. No intento de contornar esse inconveniente, foi proposto, o caráter de importância, volume por pipoca expandida por hectare (VP). O objetivo deste estudo foi desenvolver o nono ciclo

3. Efficacy and selectivity of alternative herbicides to glyphosate on maize
ABSTRACT The aim was to evaluate the selectivity and weed control of herbicides atrazine, nicosulfuron, mesotrione and tembotrione, applied alone and associated, in post-emergence of maize. Were carried out two experiments, one in the field in a randomized complete block design with four replications and eleven treatments, the second in greenhouse in a compl

4. Corn-based or high linoleic acid flushing increases productivity of Morada Nova and Brazilian Somalis ewes
RESUMO O objetivo deste estudo foi comparar flushings à base de milho (FLU), ácido linoleico alto (FAL), e tratamento controle (não suplementado, CON);dois grupos genéticos: Morada Nova (MN) e Somalis Brasileiro (SB), sobre desempenho de ovelhas e cordeiros. Foram suplementadas 156 ovelhas não prenhes três semanas antes e após a estação de monta. Ta

5. Concentrate supplementation during pregnancy and lactation of ewes affects the growth rate of lambs from a variety of crosses
The objective of this study was to determine how concentrate supplementation during late third gestation and lactation affects ewe and offspring performance from birth to weaning. Thirty-six ewes and their offspring (n = 32) were used. Eighteen Morada Nova and 18 Santa Inês ewes were artificially inseminated with semen from Dorper ram and distributed in a c

6. Reproductive responses and productive characteristics in ewes supplemented with detoxified castor meal for a long period
The objective of the present study was to evaluate the effects of supplementation with detoxified castor meal (DCM) in the diet of ewes during pregnancy, partum, and post-partum on the weight development of their offspring and at slaughter. The study included 56 ewes with synchronized estrus that were naturally mated. At the beginning of pregnancy and in pos

7. Epistasia em testecrosses de milho / Epistasis in maize testcrosses
Epistasis has been known since the beginning of the genetics studies. However its contribution to genetic variance components and to plant breeding is not well understood. Most of the genetic models designed to study the inheritance of the quantitative traits consider the absence of epistasis although most of these analyses dont provide test for such assumpt

8. Uma proposta de classificacao dos coeficientes de variacao para a cultura do milho.
Foi proposta uma classificacao dos coeficientes de variacao para a cultura do milho dos caracteres altura da planta, altura da espiga, peso de 100 graos, numero de espigas, peso de espigas, peso de graos e prolificidade com base nos dados obtidos a partir de 66 teses na area de Genbetica e Melhoramento de Plantas. Os coeficientes de variacao (CV's) foram cla

9. Avaliação de populações segregantes de melancia visando à obtenção de linhagens prolíficas e de frutos pequenos.
o presente trabalho objetivou avaliar quatro populações F2 de melancia quanto à ocorrência de plantas prolíficas de frutos pequenos e alto teor de açúcar. O experimento foi conduzido na Estação Experimental da Embrapa Semi-Árido, em Petrolina-PE. Foram avaliadas 376 plantas F2, obtidas a partir do cruzamento dos acessos PE-14 e BA-09 com os cultiva

10. Utilização de subproduto de caju (Anacardium occidentale) no desempenho reprodutivo e produtivo de ovinos criados no Nordeste do Brasil. / Use of a byproduct of cashew (Anacardium occidentale) in reproductive and productive performance of sheep raised in Northeast Brazil.
The objectives were: 1) assess the reproductive responses of ewes fed increasing levels of dehydrated cashew apple pomace (25, 50 and 75%-BCD) during the mating period, 2) check the return to cyclicity in sheep fed postpartum period prescribed in the diet include BCD, 3) assess body development and puberty age of lambs fed 50% inclusion of BCD diet, and 4) t

11. The association of two single nucleotide polymorphisms (SNPs) in growth hormone (GH) gene with litter size and superovulation response in goat-breeds
Two active mutations (A 781 G and A 1575 G) in growth hormone (GH) gene, and their associations with litter size (LS), were investigated in both a high prolificacy (Matou, n = 182) and a low prolificacy breed (Boer, n = 352) by using the PCR-RFLP method. Superovulation experiments were designed in 57 dams, in order to evaluate the effect of different genotyp

12. Análises biométricas e mapeamento de QTLS para tolerância à seca em milho / Biometric analysis and mapping of QTLS for drought tolerance in maize
One of the major goals of crop improvement is the increase in agricultural productivity associated with the improvement for the consumption in human or animal feeding. These goals can be achieved through improvements in environmental conditions or by improving the genetic potential of populations. Recently, much has been discussed about global warming, clima
