Com o objetivo de estudar a inclusão de 20, 35, 50, 65 ou 80% de farelo de melancia forrageira (Citrullus lanatus cv. citroides) (FMF) em dietas à base de feno de guandu (Cajanus cajan), foi realizado um ensaio de digestibilidade utilizando-se 20 cordeiros com 6 meses de idade e peso vivo de 11,2 ± 1,2 kg. O experimento constou de 20 dias de adaptação e 5 de coleta total de sobras e de fezes. O farelo de melancia forrageira e o feno de guandu apresentaram 95,3 e 95,75% de matéria seca (MS), 18,7 e 16,8% de proteína bruta (PB) e 38,8 e 64,3% de fibra em detergente neutro (FDN). Os níveis de farelo de melancia forrageira determinaram aumento quadrático nos consumos de MS, MO, PB, FDN, FDA, hemicelulose e carboidratos totais. O consumo de extrato etéreo não foi alterado, mas o consumo de CNF teve aumento linear conforme aumentaram os níveis de farelo de melancia forrageira. Os coeficientes de digestibilidade de MS (58%), PB (69%), FDN (41%) e EE (85%) não foram influenciados pelo nível de farelo de melancia forrageira. As digestibilidades de MO (54 a 62%), FDA (36 a 49%) e carboidratos totais (47 a 58%) variaram linear e positivamente, enquanto a digestibilidade da hemicelulose teve comportamento inverso. As dietas proporcionaram consumo de matéria seca que atendeu a exigência dos animais. Os coeficientes de digestibilidade observados foram satisfatórios. O farelo de melancia forrageira pode ser indicado para compor dietas à base de feno de guandu em níveis de 35 a 66% da matéria seca.
[Levels of forage watermelon meal in diets for sheep].
Abstract: In order to study the inclusion of forage watermelon (Citrullus lanatus var. Citroides) meal (FWM) in pigeon pea hay based diets (Cajanus cajan) (PPH), a digestibility trial in sheep was carried out for testing five levels of FWM (20, 35, 50, 65 and 80%). Twenty lambs with an average age of six months and live weight of 11.2 kg (± 1.2) were used. The experimental period was twenty days for adaptation and five days for total refuses and feces collection. The chemical composition of diet ingredients was determined, being the levels of dry matter (DM) 95.3 and 95.75%, crude protein (CP) 18.7 and 16.8%, neutral detergent fiber (NDF) 38.8 and 64.3% for WFM and PPH, respectively. The water, DM, organic matter (OM), CP, ether extract (EE), NDF, acid detergent fiber (ADF), hemicellulosis (HCEL), non-fibrous carbohydrates (NFC), total carbohydrates (TCOH) intakes, as well as the DM, MO, CP, EE, NDF, ADF, HCEL and TCOH digestibilities were accurately measured. The DM, OM, CP, NDF, ADF, HCEL and TCOH intakes showed a quadratic behavior according to the FMF levels. The ether extract intake remained unchanged, while the NFC intake was linearly positive. The DM (58%), MO (69%), NDF (41%) and EE (85%) digestibility coefficients were not significantly influenced by the forage watermelon meal levels. The OM (54 to 62%), ADF (36 to 49%) and TCOH (47 to 58%) digestibility ranged linear and positively, while the HCEL digestibility showed the opposite behavior. The experimental diets provided dry matter intake enough to meet the animal requirements. The digestibility coefficients observed were satisfactory. The forage watermelon meal can be used in the guandu hay based diets in the levels from 35 to 66% of dry matter.

The Brazilian semiarid is one of the most populous regions in the world. The main income for populations in this region is agricultural production, which in turn is limited by climatic and soil conditions. This region has environmental and economic correlations with underdeveloped regions in northwestern Africa, displaying soil surface with monotonous landscapes of smooth undulating relief with large extensions of Planosols. Climatic conditions that lead to the formation of poorly developed soils and to losses of surface layers make these soils susceptible to degradation. In the Brazilian semiarid, lithology shows that felsic rocks are the main factor in pedogenesis of Planosols, conferring the main physical, chemical, and mineralogical attributes to the soil. In this study, we evaluated the pedogenesis by weathering of gneisses (felsic rocks) in two profiles of Planosols in the Cabrobó Desertification Nucleus, Pernambuco State, northeast Brazil, highlighting the role of the parent material in the soil intrinsic characteristics in the pedogenetic processes. The primary assemblage and pedological features were determined by optical microscopy in thin sections of the A, B, and C horizons from the two soil profiles. The secondary assemblage was identified by X-ray diffractometry using the technique: SEM-scanning electron microscopy. Clay formation in situ, colluvial contribution, and elutriation process contributed to the formation of the gradient textural in both Planosols, with no evidence of argilluviation. For total regolith profile, acidic metamorphic rocks present high structural variability directly influencing the evolution of saprolites, the alteration of primary minerals, and the formation routes of secondary minerals. The secondary assemblage was rather similar and comprised illite, smectite, and kaolinite in both regoliths. The saprolite inclination in P1 favors water movement in relation to P2. The regolith in P1 shows greater mineral alteration with increased pedogenic development. MenosThe Brazilian semiarid is one of the most populous regions in the world.
