“…Previous studies have explored incorporating gin "trash" into cow, lamb, and sheep feeds [9,10,16,17]. Although CGBs are relatively low in nutritional values compared with several other feedstock materials, studies have reported the potential of utilizing CGBs as the sole feedstock or with little supplementation [2,18].

Cotton ginning generates millions of tons of byproducts every year. If not properly managed, these materials become waste, which may constitute significant environmental, economic, and logistical issues. The objectives of this study were to characterize fresh and composted cotton gin byproducts (CGBs) for utilization as animal feed supplements and investigate the effects of composting on the forage properties. The study analyzed and compared the nutrients and energy contents of fresh and composted CGB from four commercial cotton gins in Arkansas, Mississippi, Missouri, and Tennessee states, USA. The results suggest that composting CGB may result in more than a 47% increase in fiber and crude protein and at least a 25% decrease in total digestible nutrients and net energy estimations. The differences in macro- and micro-nutrient contents and feed properties suggest that composting CGB may improve the potential for utilization as an animal feed supplement. Establishing the forage properties of CGB is crucial for determining animal feed formulations using CGB as supplements.

“…Hence, attempting to find a highly degradable fiber source in young ruminants is still required. Based on this purpose, whole cottonseed, being high in energy, protein, and fiber ( Mullenix et al, 2022 ), may promote growth and stimulate functional development of the rumen especially considering its high-digestible fiber. The results gathered herein confirmed that the inclusion of WCS in the diets of dairy calves led to greater concentrate intake and greater BW after weaning compared with the control group.…”

Whole cottonseed inclusion in starter feeds improves performance, inflammometabolic profile, and rumination behavior in Holstein dairy calves

Graphical Abstract Summary: For its fat and protein contents, whole cottonseed (WCS) may be defined as a concentrate. On the other hand, its fiber is similar to that of forages in terms of effectiveness in the rumen. Considering the high digestibility of WCS fiber, its inclusion in calf starter could improve growth and rumen development. Hence, we investigated the effect of including WCS at 8% on growth performance, inflammometabolic profile, and rumen behavior in Holstein heifer calves. Calves receiving WCS in the starter showed increased average body weight (BW), improved metabolic profile, and longer rumination time compared with the control group. These results suggest that WCS may be included as a starter ingredient with beneficial effects.

Cotton gin waste (CGW) is produced in large quantities (1–1.5 × 106 metric ton/year) in the Texas High Plains (THP), one of the largest cotton-producing regions in the USA. We examined locally supplied CGW for soil amendment as biochar (CGW-BC) with a view toward rainfed cropping systems, which will likely become increasingly necessary due to declines in groundwater availability for irrigation. Sixteen unique biochar samples were produced under varying conditions of time, temperature, and post-processing wash in a muffle furnace. We performed material characterization on the biochar. We then incubated CGW-BC samples that seemed favorable for increasing the water holding capacity increase for 10 days with local, rainfed, clay loam soil. We found that increasing the pyrolysis time and temperature decreased the biochar yield but only up to 40 min. Beyond 40 min, the yield did not decrease further. Additionally, the majority of mass loss occurred during pyrolysis and not during crush-sieving or postproduction washes. CGW-BC produced at higher temperatures and for longer times had greater thermal stability. This interesting aspect of thermal stability, which did not always follow strict time‒temperature trends, may be because cotton gin waste is a heterogeneous material. We found that the addition of acid decreases the mineral content while lowering the thermal stability of lower temperature (450 °C) biochars. Regarding the CGW-BC surface area, we found that higher temperatures generally increase the micropore surface area. Using a GAB isotherm, water vapor surface area did not correlate with the highest WHC when water was added to the soil. In fact, biochar, which was pyrolyzed in less time at a lower temperature and with the use of acid washing, better held the water in soil-biochar mixtures. The measurements suggested that CGW-BC could be a valuable soil amendment that could increase the WHC without adversely increasing the pH. Our initial investigation revealed how scaled-up production of CGW-BC for soils might be economically and sustainably pursued for use in rainfed cropping, deficit irrigation, or ranchlands.
