ABSTRACT The study aimed to assess the impact of mixed silages of biomass sorghum and BRS Capiaçu with cactus pear on the fermentative profile and nutritional value. The silages included forage sorghum cv. Volumax, biomass sorghum cv. ‘BRS 716,’ BRS Capiaçu grass, a mix of 60% biomass sorghum ‘BRS 716’ with 40% Opuntia ficus indica Mill (‘Gigante’) cactus pear (based on fresh matter), and a mix of 60% BRS Capiaçu grass with 40% Opuntia ficus indica Mill (‘Gigante’) cactus pear (based on fresh matter). The experiment followed a randomized experimental design with five treatments and eight repetitions. The highest gas losses (P < 0.01) and lowest dry matter recovery (DMR; P < 0.01) were observed in the BRS Capiaçu grass and BRS Capiaçu grass with cactus pear silages. The lactic acid concentration in the biomass sorghum with cactus pear silage was 49.96% higher than in the Volumax sorghum silage . Volumax sorghum and ‘BRS 716’ biomass silages demonstrated higher DM contents (P < 0.01; mean 33.44%) compared to other silages. There was no significant difference (P = 0.24) among silages regarding the potentially degradable insoluble fraction of the DM, with a mean of 51.75%. The mixed silage of biomass sorghum with cactus pear exhibited lower losses and higher DMR. Highlights Incorporation of cactus pear into silage reduces dry matter losses. Adding cactus pear to sorghum silage enhances lactic acid contents. Incorporating cactus pear into sorghum silage improves digestibility.

ABSTRACT The objective of this study was to evaluate sorghum hybrids associated or not associated with Azospirillum brasilense and nitrogen fertilization (N) during planting on the yield, fermentative profile, and nutritional value of the respective silages. Five sorghum hybrids (Volumax, 201813B, 201814B, 201709B, BRS716) were evaluated with three nitrogen fertilization strategies using urea (100 kg ha−1 of N) and Azospirillum brasilense, and urea (100 kg ha−1 of N)/A. brasilense in association. A randomized block design was used in a 5 × 3 factorial scheme, with five hybrids, three fertilization strategies and three replications (blocks). The useful area of each experimental unit was 3 m x 3 m. The biomass sorghum hybrids showed a dry matter (DM) production (P = 0.01) 48.31% higher than the DM production of the Volumax forage (mean of 17.49 t ha−1 of dry matter). There was no difference between the sorghum hybrid silages in the pH values (mean of 4.11; P = 0.68), gas losses (mean of 3.74% of DM; P = 0.19). The sorghum hybrids biomass 201709B and BRS 716 showed better digestible and DM productivity. Azospirillum brasilense can be used as a nitrogen fertilization strategy in partial or total replacement of urea.

ABSTRACT This study addressed the different proportions of millet and sorghum silage biomass BRS 716 (BRS-716 silage) in the diet of crossbred heifers ¾ Holstein x ¼ Zebu on their nutrient intake, and digestibility, microbial protein synthesis, nitrogen balance, ingestive behaviour, and growth performance. Five experimental diets with 0, 25/75, 50/50, 75/25, and 100% of BRS-716 silage in compared to millet silage were evaluated. The roughage: concentrate ratio in the total dry matter (DM) of the diets was 75:25. The diets were evaluated in ten heifers with an initial body weight of 264.95 ± 19.4 kg (± SEM), following the experimental design in two 5 × 5 Latin squares, simultaneously. The total experimental period lasted 105 d, divided into five periods of 21 days, including a 17-d initial adaptation, and four for data collection, and samples. The increase of BRS-716 silage in the diet of crossbred dairy heifers did not change the dry matter intake (DMI), and indigestible neutral detergent fiber (iNDFI). For the purine derivatives, and microbial synthesis, there was no significant effect (P > 0.05). The average daily gain was 0.795 kg/d. The millet silage, and BRS-716 silage in the diet of crossbred Holstein × Zebu heifers used exclusively or combined in different proportions. Highlights The BRS-716 biomass sorghum silage has potential use in ruminant diet The replacement of millet silage with BRS-716 biomass sorghum silage did not change dry matter intake The replacement of millet silage with BRS-716 biomass sorghum silage maintains feed efficiency and daily weight gain of dairy heifers

Abstract The objective of this study was to evaluate the effects of different shading strategies on the intake and digestibility of nutrients, nutrient use efficiency, feeding behaviour, respiratory rate, and performance of feedlot-finished Nellore bulls in the semi-arid region of Brazil. Two hundred and twenty-five intact Nellore cattle with average body weight (BW) of 294 ± 19 kg and 24 months of age were allotted to a completely randomised design with three shading strategies (full sun, artificial shade, and natural shade). There was a significant effect of shading strategies on air temperature (p = .02), black globe temperature (p < .01), and radiant heat load (p < .01), which were 3.63%, 44.07%, and 4.10% higher in the full sun pen than in natural shade pen, respectively. The dry matter intake of animals kept in the natural shade pen was 14.76% higher than that of animals in the full sun pen (mean of 7.39 kg DM/day). The longest feeding time (p = .02) was observed in animals kept in the artificial shade pen. Bulls kept in the natural shade pen had the highest (p = .05) final body weight and average daily gain (p = .02). There was no effect of treatments on feed efficiency, averaging 0.184 kg/kg of DM. There was a trend (p = .09) towards higher hot carcase weight for animals kept in the natural shade pen. Natural shade is recommended for feedlot-finished Nellore cattle in the semi-arid region of Brazil. Highlights Natural shade in feedlot pens improves the thermal comfort of animals in the semi-arid region The dry matter intake was higher in bulls kept in the pen with natural shade than in animals kept in the full sun pen Animal performance was improved in shaded pens

Abstract The aim of the study was to determine the effect of different roughage associated with pseudostem hay of banana trees on nutrients intake, chemical composition of milk and cheese and the fatty acid profile of F1 Holstein x Zebu cows. Eight cows F1 Holstein x Zebu were used in a replicated 4 × 4 Latin square design, each composed of four animals, four treatments and four experimental periods. Four experimental diets were used: diet 1 – sorghum silage as exclusive dietary roughage; diet 2 – sorghum silage (70%) associated with 30% pseudostem hay of banana trees (dry matter basis; SS); diet 3 – 70% elephant grass (Pennisetum purpureum cv. Roxo) with 30% pseudostem hay of banana trees (dry matter basis; EGPS); and diet 4 – 70% sugar cane with 30% pseudostem hay of banana trees (dry matter basis; SCPS). The roughage: concentrate ratio in the four experimental diets was 75:25 in dry matter basis. For the chemical composition of milk and cheese, there was no difference between diets except for milk urea nitrogen which was higher with the EGPS diet. However, in the lipid fraction of milk, the EGPS diet favoured the increase of total monounsaturated fatty acids, besides increasing the concentration of conjugated linoleic acid, contributing to the improvement of some nutritional evaluation indexes of the milk lipid fraction. The pseudostem hay of banana trees associated with different roughages did not influence the chemical composition of milk and cheese of F1 Holstein x Zebu cows. Highlights The inclusion of pseudostem hay of banana trees in the diet of F1 Holstein x Zebu cows does not change the milk yield corrected for 3.5% fat. Pseudostem hay of banana trees diet of lactating cows increased the concentration of omega 6 in milk. Pseudostem hay in the diet of lactating crossbred cows did not change the yield, flavour and appearance of the cheese.
