Objective: To evaluate the productive variables and the digestibility of the nutrients of an integral diet for lambs with increasing inclusion of Samanea saman pods. Design/methodology/approach: 24 creole lambs (initial weight of 20.6 ± 0.3 kg) distributed in a completely randomized experimental design were used. The treatments were: T1, 0%, T2, 12.5%, and T3, 25% of Samanea saman pod inclusion. The productive variables and the digestibility of the nutrients were evaluated and compared with the Tukey test (? = 0.05); meanwhile, the response to the increasing content of Samanea saman was evaluated by orthogonal contrasts. The variables dry matter intake (DMI), daily weight gain (DWG) and feed conversion (FC) showed no differences (p > 0.05) between treatments. Results: Dry matter digestibility (DMD) and organic matter digestibility (OMD) increased (p <0.05) linearly, with increasing pod content. The digestibility of the neutral detergent fiber (DNDF) and acid (DADF) decreased (p < 0.05) linearly as the inclusion of Samanea saman pod increased in the diets. Limitations on study/implications: The substitution of soybean pulp by Samanea saman pod in integral diets does not affect the productive response of fattening lambs. Findings/conclusions: The use of S. saman pod is proposed as a regionally available food alternative in the feeding of ruminants in the tropics.

The aim of this study was to evaluate the performance of crossbred Holstein × Zebu steers fed on the diets containing sugarcane in natura or ensiled with two levels of concentrate (30% and 70%). A total of 32 males of 394 kg of body weight were used in a completely randomized experimental design with four treatments and seven repetitions. The animals reported a high dry matter intake (DMI) (P < 0.05) when fed on the high concentrate levels. The increase in concentrate levels resulted in an approximately 25% to 60% higher DMI as compared to the lowest level offered by silage-based diets and sugarcane in natura. The highest apparent digestibility coefficients of dry matter were observed in the diets based on sugarcane in natura (P < 0.05). The sugarcane based diets also affected (P > 0.05) the digestibility of organic matter, neutral detergent fiber, crude protein, ether extract, and non-fiber carbohydrates. There were no differences (P > 0.05) between the diets for average daily weight gain, carcass dressing, carcass gain, and feed conversion. The diets based on sugarcane in nature or ensiled with 30% and 70% concentrates do not influence the performance of crossbred Holstein × Zebu cattle.

This study aimed to evaluate the performance of feedlot lambs fed diets formulated with hay of different genotypes of Cynodon spp. and to compare the dry matter digestibility of diets using different evaluation methods (total fecal collection and chromium oxide). Suffolk crossbred neutered male lambs (n=30), with an average age of 90 days and average body weight of 21.5 kg ± 1.6. Diets were formulated using a standard concentrate and hay of the following genotypes of Cynodon dactylon: Jiggs, Vaquero, Tifton 68, Coast-Cross, Tifton 85 and Russell, in a 60:40 forage concentrate ratio, composing the treatments distributed in a randomized block design in a factorial 5 x 2 arrangement of 5 diets and 2 digestibility evaluation methods. Animals receiving Vaquero hay showed dry matter intake of 18.3; 16.9; 25.6; 20.7 and 24.2% higher than those fed hay of Jiggs, Tifton 68, Coast Cross, Tifton 85 and Russell, respectively. There was no difference between diets for digestibility using total fecal collection, chromium oxide and final weight of animals. Jiggs hay based diets allowed greater daily weight gain and better feed conversion.

The objective of this study was to evaluate nutritive values and in sacco rumen degradability of pod and leaf meals, derived from raintree (Samanea saman), in comparison with a commercial dairy feed for decision making of smallholder dairy farmers for efficient management of local feed resources. Treatments were: raintree pod meal (RPM), raintree leaf meal (RLM), and commercial dairy feed (CDF). The experiment was assigned in a completely randomized design. The results indicated that RPM, RLM, and CDF had the same amount of crude protein (CP) content (P =.17), whereas RLM was the highest in neutral detergent fiber (NDF) and acid detergent fiber (ADF) contents while CDF was the lowest in NDF and ADF (P =.001). Dry matter disappearances at various incubated times were the highest for RPM, followed by CDF, and RLM, respectively (P =.001). The rapidly soluble dry matter fraction (a) was the highest for RPM (P =.023), while the insoluble but fermentable fraction (b) was the highest for CDF (P =.001). The constant degradation rate of b (c) did not differ among treatments (P = .095). The potential degradability (PD) was the highest for CDF, compared with RPM, and RLM, respectively (P =.001). In contrast, the effective degradability (ED) parameters was the highest for RPM, followed by CDF and RLM, respectively (P =.001). Overall, this work demonstrated that RPM is more beneficial than RLM compared with CDF in nutritional values and degradability characteristics. Hence, RPM is recommended as an alternative local feed source for dairy cows raised by smallholder dairy farms in the tropics.

The use of ensiled sugarcane has been increased lately in Brazil due to the benefits that this technique represents. The objective of this study was to evaluate the effects of chemical additives on the nutritive value of sugarcane silages. The trial was carried out in a completely randomized experimental design with four replicates per treatment. The following additives were applied onto the fresh forage before ensiling: L. buchneri, lime or limestone, 1.0 and 1.5% (wet basis) each, and gypsum 1.0% (wet basis), all of them diluted into 40 L of water per ton of fresh weight of forage. The analyzed variables were: ash, crude protein, neutral detergent fiber, acid detergent fiber and organic and dry matter digestibility. The addition of lime or limestone before ensiling produced silages with higher nutritive value compared to all other treatments, due to the increase of the ash content and dry matter and organic digestibility, and also by reducing the fiber content. The crude protein content range was similar to the values observed in the fresh forage. The treatments containing L. buchneri or gypsum were ineffective in improving the nutritive value of sugarcane silages and became similar to the control silages. Treatment containing lime or limestone improved the nutritive value of the sugarcane silage.

<p>The objective of this study was to evaluate the intake, performance parameters, digestibility of dry matter, and nutrients in diets with increasing levels of metabolizable energy containing protected fat, as well as the economic analysis of the diets of ½ Boer x ½ Saanen goat kids finished in a feedlot. Twenty-eight uncastrated male goat kids with an initial weight of 19.02 ± 2.20 kg and an age of 88 ± 5.77 days were used and assigned to a completely randomized design in four diets: a control with 2.5 Mcal ME/kg DM and the others with 2.6, 2.7, and 2.8 Mcal ME/kg DM with protected fat (Lactoplus®). The animals were kept on experiment until they reached approximately 32 kg of weight. In order to estimate digestibility, we used ADFi as an internal marker. There were treatment effects on the intake of dry matter, organic matter, ether extract, and non-fiber carbohydrates. We observed a quadratic effect of diets on daily weight gain and feed conversion. The diets had no effect on the digestibility of dry matter, organic matter, neutral detergent fiber, or gross energy. The digestibility of non-fiber carbohydrates and total carbohydrates showed a linear decrease, and crude protein increased linearly. We observed a quadratic behavior in ether extract digestibility resulting from the inclusion of protected fat in the diets. The serum cholesterol level was influenced by the diets and showed a linear increase. The economic evaluation was favorable, with a larger net revenue value for the diet with 2.5 Mcal ME/kg DM. The increase of energy density of diet for ½ Boer x ½ Saanen goat kid through the inclusion of protected fat influences negatively the intake of dry matter and the digestibility of non-fiber carbohydrates and total carbohydrates without improving the growth performance of the animals.</p>

Two trials were conducted aiming to determine the chemical composition, the digestibility of nutrients and energy from dehydrated cashew apple meal, as well as to evaluate the effects generated by including increasing levels (0, 10, 20, 30, 40 and 50%) of this ingredient in growing rabbit feed, on performance, carcass characteristics and economic evaluation. In the digestibility trial, were used 24 rabbits with 55 days of age, distributed in a completely randomized design with two treatments and twelve repetitions, being one reference feed and the other test feed, composed by 70% of the reference feed and 30% DCAM. The coefficients of the dry matter digestibility, crude protein and gross energy of the DCAM were, respectively, 67.79; 30.03 and 48.61%. The digestible dry matter, digestible protein and digestible energy, based on dry matter, were, respectively, 59.55%; 4.76% and 2,119.66 kcal/kg. In the second trial, 120 mixed breed rabbits were used, with an average of 45 days of age and weight 1143 ± 153g. The animals were distributed in a completely randomized design, with six treatments and ten repetitions with two rabbits of the same sex per cage. It was observed that the inclusion of DCAM did not affect (P > 0.05) the feed intake, but reduced (P < 0.05) the feed conversion efficiency, as well as a linear reduction in carcass yield. A quadratic effect on daily weight gain and the ratio meat/bone was observed, with better inclusion level estimated at 25.31 and 24.65%, respectively. The inclusion of DCAM linearly improved economic viability to the level of 50%, however not to harm the weight gain and the ratio meat/bone, it is recommended to include up to 25%.

ABSTRACT The aim of this study was to evaluate diets substituting corn grain with passion fruit peels on the consumption, ingestive behavior, digestibility of diets and sheep performance. A total of 20 sheep were used, confined in individual pens, fed twice a day, with diets which included passion fruit peels in the proportions of 0; 25; 50; 75 and 100% replacing corn grain. The corn grain represented 70% of the dry matter of the diet and the passion fruit peels were supplied in dehydrated form. The experimental design was completely randomized with five treatments and four replicates. The data were submitted to analysis of variance and regression analysis at the significance level of 5%. There was a linear increase in dry matter consumption with an increase of 3.89 g for each inclusion level of passion fruit peel. The apparent digestibility of dry matter decreased and neutral detergent fiber increased linearly with the substitution of corn grain with passion fruit peels. The feeding, rumination, leisure and water intake times presented averages of 3.74; 2.92; 16.92 and 0.42 hours, and were not influenced by the diets (P>0.05). The average daily weight gain was similar for the animals in the different diets and consequently the final weight presented average values of 0.226 kg day-1 and 32.1 kg, respectively. The inclusion of passion fruit peels in the sheep diet is an interesting alternative because even with the reduced dry matter digestibility, it increased the consumption and promoted similar weight gains.

This trial aimed to analyze the replacement of forage sorghum silage (FS silage) with biomass sorghum silage (BRS 716 silage) in diets for heifers ¾ Holstein x ¼ Zebu on their nutrient intake and digestibility, nitrogen balance, microbial production, feeding behavior, and animal performance. Eight heifers with average age 18±4 months (mo) and average body weight (BW) 271 ± 57 kg were used. The experimental design was double-Latin square, 4×4, being four diets, four experimental periods and four animals. Four experimental diets with 0, 33, 67 and 100% substitution of forage sorghum silage with biomass sorghum silage were used. The roughage:concentrate ratio in the total dry matter (DM) of the diets was 75:25. The fraction “b” of DM was higher in the BRS 716 silage. There was no difference (p> 0.05) for dry matter intake (DMI; p = 0.45) and total digestible nutrients intake (p = 0.76). The dry matter digestibility (DMD), crude protein, ether extract and neutral detergent fiber increased linearly with the inclusion of BRS 716 silage. The feeding times, ruminating and idle have not been changed (p > 0.05). The replacement of FS silage with BRS 716 silage did not modify the average daily weight gain (ADG; p > 0.05; mean 1.30 ± 0.025 kg). Biomass sorghum silage can replace up to 100% forage sorghum silage in the diets of ¾ Holstein x ¼ Zebu heifers.

New Zealand White Rabbits

The objective of this study was to evaluate the performance and digestibility of diets containing different levels of crude propolis for growing rabbits. Forty-eight New Zealand White rabbits, 43 days old, of both genders, were used, distributed in a completely randomized design. There were four diets with different inclusion levels of crude propolis (0.0; 0.5; 1.0 and 1.5%). There was no statistical difference for performance regarding the inclusion levels of crude propolis (p = 0.85), as well as for the variables dry matter consumption, neutral detergent fiber and acid detergent fiber (p ≥ 0.07). Crude protein consumption showed a statistical difference in relation to gender (p = 0.04): males showed higher consumption. However, final weight, total weight gain, daily weight gain and feed efficiency were not influenced by the addition of crude propolis (p ≥ 0.37). Dry matter digestibility, crude protein, neutral detergent fiber and acid detergent fiber were not influenced by the inclusion levels of crude propolis in the diets (p ≥ 0.12). This study indicates that the inclusion of raw propolis up to 1.5% in the diets does not affect the performance parameters of rabbits.

This research was conducted to determine the effects of selected inoculant on the silage with different wilting times. The ryes were unwilted or wilted for 12 h. Each rye forage was ensiled for 100 d in quadruplicate with commercial inoculant (Lactobacillus plantarum sp.; LPT) or selected inoculant (Lactobacillus brevis 100D8 and Leuconostoc holzapfelii 5H4 at 1:1 ratio; MIX). In vitro dry matter digestibility and in vitro neutral detergent fiber digestibility were highest in the unwilted MIX silages (p < 0.05), and the concentration of ruminal acetate was increased in MIX silages (p < 0.001; 61.4% vs. 60.3%) by the increase of neutral detergent fiber digestibility. The concentration of ruminal ammonia-N was increased in wilted silages (p < 0.001; 34.8% vs. 21.1%). The yeast count was lower in the MIX silages than in the LPT silages (p < 0.05) due to a higher concentration of acetate in MIX silages (p < 0.05). Aerobic stability was highest in the wilted MIX silages (p < 0.05). In conclusion, the MIX inoculation increased aerobic stability and improved fiber digestibility. As a result of the wilting process, ammonia-N in silage decreased but ruminal ammonia-N increased. Notably, the wilted silage with applied mixed inoculant had the highest aerobic stability.
