“…Certainly, these differences in CP content result from improved soil conditions (soil plowing and fertilization) or are due to the part of the plant considered in the analysis (only leaves or branches with smaller diameter). Crude protein content of other native trees is known to range from 11.25%<CP<14.00% (CORDÃO et al, 2013;COSTA et al, 2010;FORMIGA et al, 2011;GONZAGA NETO et al, 2004;MENDONÇA JÚNIOR et al, 2008). This data shows the potential of M. glaziovii and other tree species growing in the Caatinga to produce protein-rich forage; it also suggests that trees should be maintained in the production systems of cattle ranching practiced in the region because this can help ensure quantity and quality of forage as well as soil protection and animal comfort, resulting from the presence of trees in the rangeland.…”

The growth and forage production of Manihot glaziovii were evaluated in plants growing in Itapetim-PE, Brazil via a complete block experimental design with four treatments (0, 33, 50, and 100% branch cutting intensity) to analyze increases in height and diameter. Furthermore, 3×2 factorial treatments (three branch cutting intensities: 33, 50, and 100% as well as two types of collected forage material: Branches with diameter < 10 mm and corresponding sprouts on the same branches 1 year after being cut) were analyzed for improvement in forage quantity and quality parameters. Height increase was affected (P < 0.05) by branch cutting intensity (0.29, 0.11, 0.43, and -0.04 m plant -1 , respectively, for 0, 33, 50, and 100% branch cutting intensities), while the increase in diameter was not affected (P > 0.05) (3.97 mm plant -1 was the overall mean increase). Cutting intensity×type of collected material, in combination, affected (P < 0.05) the quantity of the collected forage: means were considered similar (P > 0.05) in the first (branches) and second (sprouts) forage collection events for 33% (0.66 and 0.75 kg dry matter plant -1 , respectively) and 50% (1.40 and 1.73 kg dry matter plant -1 , respectively) cutting intensities; it decreased (P < 0.05) from the first to the second collection events, when 100% of branches and sprouts were harvested (3.37 and 2.06 kg dry matter plant -1 , respectively). The combined effects of aforementioned parameters were observed (P < 0.05) as interactions for some forage quality variables. Neutral detergent fiber content remained constant (P > 0.05) between 50.57 and 54.41% in forage containing branch and sprouts from 33 and 50% cutting intensities. It increased (P < 0.05) to 62.20% in sprouts from 100% cutting intensity. Acid detergent fiber content increased (P < 0.05) from around 38.4% to 46.63% in sprouts from plants subjected to 100% cutting intensity. The crude protein (between 8.72 and 10.08%) and ether extract (between 2.74 and 4.35%) contents were unaffected (P > 0.05) by these factors. Mineral matter content was higher (P < 0.05) in sprouts from all cutting intensities with 5.9% being the highest. Up to 50% of Manihot glaziovii branches with Ø < 10 mm and corresponding 1-year-old sprouts can be pruned with no negative effect on the quality and quantity (up to 1.73 kg dry matter plant -1 ) of the collected forage.

ResumoO crescimento e a produção de forragem de Manihot glaziovii foram avaliados em plantas se desenvolvendo em Itapetim-PE, Brasil, através de um experimento no delineamento em blocos casualizados com 4 tratamentos (intensidades de corte dos ramos: 0, 33, 50 e 100%) para analisar o aumento em altura e diâmetro. Adicionalmente, foram considerados3x2 tratamentos fatoriais (três intensidades de corte dos ramos: 33, 50 e 100%, e dois tipos de material forrageiro coletado: Ramos com diâmetro < 10mm e respectivas rebrotas desses 1 ano após serem cortados) para analisar parâmetros de quant...

Context Tannins are polyphenolic compounds found in legumes, trees and forage shrubs, such as Mimosa tenuiflora, and form hydrogen bonds with proteins. Aims The objective of the present study was to determine the optimal dietary concentration of natural tannins from M. tenuiflora for enhancing intake, digestibility, nitrogen (N) and tannin physiological balance, performance, carcass traits and commercial cuts of lambs. Methods Forty-eight uncastrated Santa Ines lambs were distributed between two experiments, each with four diets containing natural tannins (1.21 (control), 9.29, 17.4 and 25.4 g/kg dry matter (DM) total) from M. tenuiflora hay. Key results With increasing level of inclusion of natural tannins from M. tenuiflora hay in the diet, there were quadratic increases (P ≤ 0.05; up to 17.4 g/kg DM inclusion) in the daily nutrient intake, N faecal excretion, N urinary excretion, performance, carcass traits and rib and loin commercial cut weights of lambs. However, intake, faecal excretion, physiological balance of tannins and carcass leg circumference increased (P ≤ 0.05) linearly with an increasing inclusion of tannins from M. tenuiflora hay. Furthermore, there were linear decreases (P ≤ 0.05) in the digestibility of DM, crude protein, neutral detergent fibre corrected for ash and protein, acid detergent fibre, non-fibrous carbohydrate and total digestible nutrients and decreases in faecal excretion of total phenolic compounds and feeding efficiency in lambs with increasing dietary concentration of tannins. Conclusions It is recommended that M. tenuiflora hay replace Brachiaria decumbens hay at 250 g/kg of dietary roughage, corresponding to 17.4 g/kg DM of tannins, in the diet of Santa Ines finishing lambs because the resulting increased bioavailability of tannins improves nutrient intake, N retention, average daily gain, carcass weight and the weights of the most profitable cuts (leg, loin and rib). Implications The use of M. tenuiflora legume (which is common in the Caatinga biome) as hay roughage in the lamb diet increases tannin bioavailability and the efficiency of protein use, consequently improving performance and contributing to the economic viability of sheep production in the region.
