Cruzaram-se, na Fazenda Iracema, da Empresa de Pesquisa Agropecuaria do Ceara - EPACE -, em Quixada, CE, 420 cabras Sem Raça Definida (SRD) com reprodutores das raças e/ou tipos Nativos - Marota, Canindé, Moxoto, Repartida e SRD - e exoticas Anglo-Nubiana e Bhuj. Pesaram-se as crias ao nascer e a intervalos de 28 dias até 112 dias (desmama) e a cada dois meses, até 12 meses. 0 peso ao nascer, dos descendentes de raças exoticas, foi maior que o das lrças nativas. Subseqüentemente, os pesos foram idênticos em todos os grupos, refletindo efeito materno. Aos 12 meses, os descendentes de Anglo-Nubiana tenderam a ser mais pesados que os de Bhuj e SRD, e estes, que aqueles das raças nativas (22,09; 20,55 e 19 kg). Os descendentes das raças nativas foram levemente inferiores aos de SRD, mostrando que essas raças podem estar estreitamente relacionadas corn o tipo SRD. Os machos foram mais pesados que as fêmeas, ao nascer (2,28 e 1,94 kg) e no período pos-desmama. Os nascidos de partos simples foram mais pesados que os nascidos de partos gemelares, até seis meses de idade. 0 peso da mae no parto influenciou o peso das crias no nascimento. [Cross-breed effect upon the growth of goats in Ceará state]. Abstract: Four hundred and twenty SRD (nondescripted breed) does were cross-breeded at Iracerna Farm of the Empresa de Pesquisa Agropecuária do Ceará in Quixadá, Ceará, CE, Brazil, with sires of the nativo breeds Marota, Canindé, Repartida, Moxotó and SRD and exotic breeds Anglo-Nubian and Bhuj. The kids were weighed at birth and each 28 days up to weaning and each two months frorn weaning to 12 months of age. At birth, livo weight were higher for exotics cross-breeded kids as compared to native ones. Subsequently, live weights were the sarne for ali kids, showing great maternal effect on the growth of kids. By 12 rnonths old Anglo-Nubian cross-breeded kids were heavier than Bhuj and SRD, and these were heavier than the nativo ones (22.09, 20.55 and 19kg). Nativa breed progeny did not show advantage over SRD crosses. This suggests that native breeds may be closely reiated to SRD. Male kids were havier than female at birth (2.28 to 1.94 kg), and even during post-weaning growth. Kids bom single were heavier than twins from birth to Mx month old. Does weight at parturition affected the kids weight at birth.

Three field experiments were carried out in 1997/1998, 1998/1999 and 1999/2000 to investigate the relationship between severity (S) of alternaria leaf spot, caused by Alternaria helianthi, area under disease progress curve (AUDPC), healthy leaf area index at any given day (HLAI), healthy leaf area duration (HAD), radiation intercepted by healthy leaf area at any given day (HRI), total healthy leaf area absorption (HAA), and yield components of sunflower sown on four dates. AUDPC showed a relationship with yield in two years, following the negative exponential model coefficient of determination (R2 = 0·79 and 0·60). The HAD?yield relationship was linear for each of three trials (0·73 < R2 < 0·83). Among the integral variables analysed, the HAA?yield relationship was the best, fitted by the exponential model (0·77 < R2 < 0·89). Single-point models using disease severity, HLAI and HRI to estimate yield at various times during the crop season were tested. The slope of the severity?yield relationship was stable from the R1 (inflorescence visible) growth stage. The HLAI?yield relationship was stable between R1 and R6 (anthesis completed) and increased from the R7 (first phase of achene development) stage. The HRI?yield relationship was variable and not stable. The relationship between severity and yield in the R3 (second phase of inflorescence elongation) growth stage proved that plants with disease severity higher than 10% had yield lower than 500 kg ha1, regardless of the sowing date. This value can be used as a damage threshold for the disease. Disease severity can be used as an independent variable in a sunflower?-alternaria leaf spot management system and can be used to produce recommendations at the research level, such as genetic breeding for disease resistance or studies on sowing date.
