SUMMARY This study agronomically evaluated 14 sorghum genotypes in the Brazilian semi-arid region. A randomized complete block design, with the treatments represented by sorghum genotypes and three replicates, was used. The dry matter (DM), plant height (PH), number of live leaves, fresh matter production (FMP), dry matter production (DMP), leaf blade (LB), stem, panicle (PAN), dead material, water accumulation...
SUMMARY This study evaluated the characteristics of carcass and commercial cuts of Santa Ines lambs of different biotypes (traditional and modern) slaughtered at 32 kg and 34 kg. The thirty-six Santa Ines sheep used, of which 18 traditional and 18 modern biotypes were on average 180 days old and weighed 16 kg initially. The animals were kept in individual stalls (0.80 × 1.20 m) until they reached the slaughteri...
SUMMARY This study aimed to evaluate the bio-economic performance in confinement crossbred goats from different genetic groups. Were used 30 goats, crossbred (F1) intact male, 10 goats Boer x SPRD (undefined breed), 10 x Savannah SPRD and 10 Oberhasli x SPRD, with an average weight of 15 kg and an average age of 100 days. The initial weight was evaluated, final body weight, average daily gain, total weight gain...
Objetivou-se com este estudo avaliar o resultado econômico da terminação de ovinos em confinamento, alimentados com silagens de diferentes cultivares de sorgo: 'BRS 810' e 'BRS Ponta Negra' (caráter forrageiro); 'BRS 610' (caráter duplo propósito); e 'BRS 655' e 'BRS 800' (caráter granífero). Utilizaram-se 35 cordeiros, sem padrão racial definido, com idade entre 5 e 7 meses e com peso vivo médio de 17,7±3,7kg....
This study aimed to evaluate the fermentation characteristics, losses and the chemical composition of two pearl millet genotypes silages submitted to nitrogen fertilization. The experimental design was a completely randomized blocks in a split plot scheme 2x5 (two nitrogen genotypes doses x five doses of nitrogen), with four replicates. Nitrogen doses were 0, 20, 40, 60, 80kg ha-1 and the pearl millet genotypes...
Thirty-five feedlot lambs (without defined breed, aged between 5 and 7 months, with average live weight of 17.7±3.7 kg) were used in a completely randomized design to evaluate the effect of diets containing different genotypes of sorghum on morphometric measurements and qualitative characteristics of carcass and yields of primal cuts. The animals stayed in individual indoor pens for 42 days and slaughtered at a...
Objetivou-se quantificar o rendimento forrageiro, o percentual de componentes da planta, as características morfométricas e a eficiência do uso da chuva de cinco genótipos de sorgo para silagem no semiárido paraibano. O experimento foi conduzido na Estação Experimental Pendência, no município de Soledade-PB. O delineamento experimental utilizado foi em blocos casualizados, com quatro repetições, sendo os tratam...
Objetivou-se com esta pesquisa avaliar o rendimento forrageiro, as características agronômicas e morfométricas das plantas e as perdas, perfil fermentativo e composição bromatológica de silagens de genótipos de milheto. Para avaliação das características agronômicas e morfométricas dos genótipos utilizou-se o delineamento experimental em blocos casualizados, com cinco repetições. Na fase de avaliação dos silos ...
Objetivou-se avaliar o efeito de níveis de adubação orgânica utilizando esterco caprino e duas alturas de resíduo, sobre a produção de fitomassa do capim-buffel. Utilizou-se parcelas subdivididas, no delineamento experimental de blocos completos ao acaso, com cinco repetições. As parcelas consistiram de doses de esterco caprino (0; 5; 10; 15 e 20t/ha), e as subparcelas consistiram em duas alturas de resíduo (10...
This study aims to evaluate the tissue development through real time ultrasound of lambs before slaughter in feedlot. It has been used thirty non-castrated lambs; being 10 Dorper x undefined breed, 10 Santa Inês x undefined breed and 10 undefined breed. The experimental units were about 120 days of age and 19,31kg weight of in average. The lambs have received a single and complete diet, containing 15,5% of crud...
