“…The livestock sector is a significant sponsor to Gross Domestic Product (GDP) of several arid and semi-arid countries of the world, including Pakistan [11,12,21]. In fact, >33% of agriculture lands is utilized by growers for cultivation of forages and grasses of high nutritional value [22]. In several Asian and African countries, more than 30% of the available land has been dedicated for cultivation of green fodder crops which are an extensive example of a fresh water consumer [22,23].…”

In several Asian and African countries, more than 30% of the available land has been dedicated for cultivation of green fodder crops which are an extensive example of a fresh water consumer [22,23]. According to several literature reports, approximately 85 L of water has been consumed to produce 1 kg of forage crops, which is expensively higher than to produce vegetables that only require as little as 43 L of water per kg [24].…”

Exposure to toxic metals (TMs) such as cobalt (Co) can cause lifelong carcinogenic disorders and mutagenic outcomes. TMs enter ground water and rivers from human activity, anthropogenic contamination, and the ecological environment. The present study was conducted to evaluate the influence of sewage water irrigation on cobalt (Co) toxicity and bioaccumulation in a soil-plant environment and to assess the health risk of grazing livestock via forage consumption. Cobalt is a very necessary element for the growth of plants and animals; however, higher concentrations have toxic impacts. Measurement of Co in plant, soil and water samples was conducted via wet digestion method using an atomic absorption spectrophotometer. The Co pollution severity was examined in soil, forage crops (Sorghum bicolor Kuntze, Sesbania bispinosa (Jacq.) W. Wight, Cynodon dactylon (L.) Pers., Suaeda fruticosa (L.) Forssk. and Tribulus terrestris L.) in blood, hair and feces of sheep, cow and buffalo from district Toba-Tek-Singh, Punjab, Pakistan. Three sites were selected for investigation of Co level in soil and forage samples. Highest concentration of Co was 0.65 and 0.35 mg/kg occurring in S. bicolor at site I. The sheep blood, cow hair and sheep feces samples showed highest concentrations of 0.545, 0.549 and 0.548 mg/kg, respectively at site I and site II. Bioconcentration factor, pollution load index, enrichment factor and daily intake were found to be higher (0.667, 0.124, 0.12 and 0.0007 mg/kg) in soil, S. bicolor, S. fruticosa and in buffalo, respectively, at site I. It was concluded that forage species irrigated with wastewater are safe for consumption of livestock. However, though the general values were lower than the permissible maximum limit, it was observed that the bioaccumulation in the forage species was higher. Therefore, soil and food chain components should be avoided from trace metal contamination, and other means of nonconventional water resources should be employed for forages irrigation.

Climate change is characterized by an increasing in temperature, drought, and an increase in CO2. This paper aims to propose the right strategy to deal with climate change in forage crops. Plant adaptation mechanisms include increasing water content, cell membrane stability, and photosynthetic capacity by suppressing stomata conductance and C consumption through respiration. The impacts of climate change on animal feed crops include: decreased productivity and nutrient content, and reduced planting area which affects the supply of animal feed so that food availability is disrupted. Adaptation strategies are carried out by managing the cultivation of forage plants, including selecting planting and harvesting times, as well as irrigation. Besides, it is necessary to select adaptive fodder plants through breeding. Breeding methods are conducted through the exploration of genetic resources to compile new superior forage adaptive crops to climate change. Recommendations for adaptable forage include: sorghum, Brachiaria humidicola, Napier grass (Pennisetum purpureum).

“…It is widely cultivated worldwide because of its broad adaptability and tolerance to drought, waterlogging, and salinity ( Rooney et al, 2007 ). In addition, cultivation of forage sorghum has recently increased to meet the demand of growing domestic animal production industries, especially in arid and semi-arid regions with perennial water shortages ( Huang et al, 2020 ). Genetic dissection of sorghum yield traits will facilitate the development of sorghum as a high-yielding forage crop that can be used for animal production.…”

Genetic dissection of forage yield traits is critical to the development of sorghum as a forage crop. In the present study, association mapping was performed with 85,585 SNP markers on four forage yield traits, namely plant height (PH), tiller number (TN), stem diameter (SD), and fresh weight per plant (FW) among 245 sorghum accessions evaluated in four environments. A total of 338 SNPs or quantitative trait nucleotides (QTNs) were associated with the four traits, and 21 of these QTNs were detected in at least two environments, including four QTNs for PH, ten for TN, six for SD, and one for FW. To identify candidate genes, dynamic transcriptome expression profiling was performed at four stages of sorghum development. One hundred and six differentially expressed genes (DEGs) that were enriched in hormone signal transduction pathways were found in all stages. Weighted gene correlation network analysis for PH and SD indicated that eight modules were significantly correlated with PH and that three modules were significantly correlated with SD. The blue module had the highest positive correlation with PH and SD, and the turquoise module had the highest negative correlation with PH and SD. Eight candidate genes were identified through the integration of genome-wide association studies (GWAS) and RNA sequencing. Sobic.004G143900, an indole-3-glycerol phosphate synthase gene that is involved in indoleacetic acid biosynthesis, was down-regulated as sorghum plants grew in height and was identified in the blue module, and Sobic.003G375100, an SD candidate gene, encoded a DNA repair RAD52-like protein 1 that plays a critical role in DNA repair-linked cell cycle progression. These findings demonstrate that the integrative analysis of omics data is a promising approach to identify candidate genes for complex traits.
