investigated the effect of diets with different ratios of C4:C3 plant materials
on CH <sub>4 </sub>, CO <sub>2 </sub>, and N <sub>2 </sub>O emissions from manure
produced by Awassi ewes. The
trial compared the production of greenhouse gases from manures produced by
sheep fed diets with low C4:C3 ratios (Group A–0.95:1) to those fed high C4:C3
plant ratios (Groups B–1:1; C–1.5:1; D–2:1). The trial was a randomized design
with four groups and each group contained four sheep (total 16). The main
feedstuffs were alfalfa and maize based combinations with similar nutrient
contents. The body weight gain (BWG) and the feed conversion ratio (FCR) of the
sheep were affected by C4:C3 ratio. They increased in the higher C4
plant-consuming groups, despite similar feed consumption. Manure components
were not affected by the feed ratio, except for N, pH, and Neutral detergent
fiber (NDF). Total diet digestibility of N increased cubically when maize silage
was included (Groups B and D). The use of C3 plants as forage or grain sources
led to increased manure and manure gas production (P = 0.04 and linear effect:
0.03). Regardless of the C4:C3 ratio, alfalfa increased N <sub>2 </sub>O
emissions from manures because more manure was produced by groups A and C. T </span> <span lang="en-us" style="line-height:150%;font-size:10pt;" xml:lang="en-us">he temperature, humidity and mold of the manures were
