“…Forage sorghum [Sorghum bicolor (L.) Moench] is a C 4 crop widely adapted to different environmental conditions, with high water use efficiency, forage yield, and a less demanding fertility than other agricultural crops (Híbrido BRS 655…, 2009;Borba et al, 2012;Cardoso et al, 2012;Qu et al, 2014;Barcelos et al, 2016;BRS 658…, 2016;Tolentino et al, 2016;Pino & Heinrichs 2017;Manarelli et al, 2019). Among the forage sorghum hybrids available in the market, 'BRS 655' and 'BRS 658' hybrids stand out for their productive stability, resistance to drought and high-quality forage, with high levels of protein and digestibility (Híbrido BRS 655…, 2009;BRS 658…, 2016).…”

The objective of this work was to define the optimal plot size and number of replicates for the evaluation of the fresh weight of sorghum (Sorghum bicolor) hybrids. Thirty-two uniformity trials were carried out with two hybrids, in two sowing dates and four evaluation periods. Each trial was divided into 48 basic experimental units (BEUs) of 0.5 m2, and fresh weight was determined for each BEU. The mean, variance, coefficient of variation, first-order spatial autocorrelation coefficient, optimal plot size, and coefficient of variation of the optimal plot size were calculated. The number of replicates was determined on the basis of the largest calculated plot size, through an iterative process, for the combinations of number of treatments and differences among means to be detected as significant by Tukey’s test, at 5% probability. The optimal plot size ranged from 1.79 to 2.58 m2, and the number of replicates from 2.6 (~3) to 49.2 (~50). The optimal plot size is 2.58 m2, and five replicates are sufficient to identify as significant the differences between treatment means of 35%.

“…Originating in Africa, sorghum is adapted to grow in arid and semi-arid environments (Hmielowski, 2017;Manarelli et al, 2019). As it is a plant with C4 metabolism, it has high photosynthetic capacity with great inherent potential for biomass production.…”

Forage sorghum is a crop that can be planted in semiarid regions, due to its greater adaptability to dry climate environments, and can replace maize in these regions, which are often unsuitable for its production. Thus, the objective of the study was to evaluate the structural, morphological and nutritional characteristics of 23 sorghum hybrids forage cultivated in rainfed conditions, planted in different climate conditions, comparing the hybrids, in order to determine what produces the best in the climatic conditions of the explored region, and also to indicate whether this crop can be planted as a replacement for maize in environments not suitable for planting it. The research was conducted in climate BSh in the Municipality of Alvorada do Gurgueia, and climate Aw in the Municipality of Bom Jesus, both in the state of Piauí from 2014 to 2015. Each trial consisted of 20 experimental forage sorghum hybrids [Sorghum bicolor (L.) Moench], and three commercial hybrids. A randomized block design was used, with three replications in a factorial scheme (2 × 23). The growth characteristics determined were hybrid × climate interaction for the variables plant height, lodging and leaf/stem ratio. For the variable number of tillers, there was a significant difference only between hybrids. There was no difference between hybrids only for the lodging variable of climate Aw. The other variables showed a difference in all hybrids evaluated. There was an interaction for production of dead matter and total dry forage mass between the different environments and hybrids evaluated. For leaf production, there was an effect only for the different environments. For the chemical characteristics, there was an interaction for all variables analyzed between the different environments and hybrids evaluated. The semi-arid region of the State of Piauí, climate BSh which presents a high climatic risk for maize cultivation, proved to be favorable for forage sorghum production. The forage sorghum also presented agronomic characteristics similar to those found in semi humid climate Aw, a favorable region for maize cultivation. In addition, the tested hybrids showed good chemical characteristics, so the BSh climate has great exploratory potential for the cultivation of forage sorghum.

“…The diet of lambs can modify their carcass conformation and meat physical-chemical and organoleptic properties, such as fatty acid profile, softness and colour (Franco, Crecente, Vá zquez, Gómez, & Lorenzo, 2013). The silage offered to animals can affect the quality of their final products, such as milk and meat (Campos et al, 2017;Milewski et al, 2014), denoting the importance of studies that investigate the diet effects (Holanda Júnior, 2006;Manarelli et al, 2019;Pereira et al, 2016). Considering that other studies (Manarelli et al, 2019;Orrico Junior et al, 2015) found variations in the effect of 'BRS506' saccharin sorghum silage on animal performance and carcass characteristics, it is important to evaluate the quality parameters of meat of sheep fed with this silage.…”

The objective of this work was to evaluate the qualitative and sensory characteristics and the fatty acid profiles of the meat of lambs fed with silages of two saccharine sorghum varieties and compare them with forage sorghum and maize silages. Twenty non-castrated male Suffolk lambs were arranged in a completely randomised block design, and the treatments consisted of the following silages: forage sorghum (FORSOR), saccharine sorghum ('BRS506'), saccharine sorghum ('BRS511') and maize (MAIZE). The animals were slaughtered after 70 days in the feedlot. The carcasses were cooled at 4 °C for 24 h. The longissimus thoracis et lumborum muscle was removed for analysis. No differences (p > 0.05) between treatments were found for chemical composition and qualitative and sensory characteristics of the evaluated meat. Lambs fed with 'BRS506' presented muscles with higher total unsaturated and monounsaturated fatty acids and with higher percentages of oleic acid. The BRS506 saccharin sorghum silage increased the meat total unsaturated and monounsaturated fatty acid contents, which are beneficial to human health; thus, this silage can replace maize silage in the feed for finishing lambs.
