The Caatinga Domain is exclusively Brazilian, covered by vegetation exhibiting a great diversity of species, which have morphological and physiological characteristics determined by environmental conditions. These attributes define quantity and quality litterfall deposition on the soil. The litterfall deposition seasonality was monitored a fragment of Caatinga vegetation, located in the semiarid region of Brazil, from 2016 to 2017. The decomposition rate, mean residence time for litterfall (50 and 95%), and the exportation of mineral nutrients via deciduous material were determined. Data from meteorological variables and litterfall were used in the elaboration of Pearson's correlation matrix, and multicollinearity, canonical and path analyzes. The Caatinga deposited on average 637 kg DM (dry mass) ha−1 year−1 litterfall, including 53% leaves, 26% twigs, 15% reproductive structures and 6% miscellanea, with deposition peaks between the months of March and July, with values above 57 kg MS ha−1. Global solar radiation, vapor pressure deficit, soil heat flux, rainfall and normalized difference vegetation index are controlling factors the litterfall deposition. The decomposition rate of the litterfall was 0.33 kg DM ha−1 year−1, while the time required for the disappearance of 50% and 95% of the litterfall was respectively 2.1 and 9.1 years, and the exportation of nutrients was 13.59 kg ha−1 year−1. Litterfall deposition was determined by the environmental conditions and physiological responses of the vegetation, which are fundamental to maintaining the Caatinga Domain.

ABSTRACT - The objective of this work was to evaluate the silage quality, fermentation profile, intake, and digestibility of six sorghum cultivars for sheep feeding. 'SF 15', 'IPA 2502', 'BRS 655', 'BR 601', 'BRS 506', and 'Sudão' were cultivated in randomized complete block designs with five replicates, harvested, and ensiled when plants reached the soft-dough grain stage. Silage quality was determined in laboratory silos. Intake and apparent digestibility were determined during 22 days, using 24 Santa Inês lambs (35.5±2.21 kg) randomly distributed in the treatments. Silage from 'IPA 2502' had the lowest contents of dry matter, neutral detergent fiber, and acid detergent fiber; the highest nonfibrous carbohydrate and total digestible nutrient contents; and the greatest dry matter degradability. Silages from 'BR 601' and 'BRS 506' showed the highest values of crude protein, whereas those of 'SF 15' and 'Sudão' had the highest levels of fibrous fractions. Lambs fed silage from 'IPA 2502' consumed more dry matter and nonfibrous carbohydrates, and their crude protein digestibility was also greater than that from the consumption of other cultivar silages. 'IPA 2502' stands out for its nutritional characteristics, which resulted in better animal performance. RESUMO - O objetivo deste trabalho foi avaliar a qualidade da silagem, o perfil de fermentação, o consumo e a digestibilidade de seis cultivares de sorgo para alimentação de ovinos. 'SF 15', 'IPA 2502', 'BRS 655', 'BR 601', 'BRS 506' e 'Sudão' foram cultivadas em delineamento de blocos ao acaso com cinco repetições, colhidos e ensilados quando as plantas atingiram o estádio pastoso da maturidade dos grãos. A qualidade da silagem foi determinada em silos de laboratório. O consumo e a digestibilidade aparente foram determinados durante 22 dias, tendo-se utilizado 24 cordeiros da raça Santa Inês (35,5±2,21 kg) distribuídos aleatoriamente entre os tratamentos. A silagem de 'IPA 2502' apresentou os menores teores de matéria seca, fibra em detergente neutro e fibra em detergente ácido; os maiores teores de carboidratos não fibrosos e nutrientes digestíveis totais; e a maior degradabilidade da matéria seca. As silagens oriundas de 'BR 601' e 'BRS 506' apresentaram os maiores valores de proteína bruta, enquanto aquelas de 'SF 15' e 'Sudão', os maiores teores das frações fibrosas. Os cordeiros alimentados com a silagem de 'IPA 2502' consumiram mais matéria seca e carboidratos não fibrosos, e a sua digestibilidade de proteína bruta também foi maior do que a oriunda do consumo da silagem de outras cultivares. 'IPA 2502' destaca-se por suas características nutricionais, as quais resultaram em melhor desempenho animal.
