The objective of this study was to compare methane emission by goats consuming the condensed tannin-containing forage sericea lespedeza (Les-pedeza cuneata) or a mixture crabgrass (Digitaria ischaemum) and Kentucky 31 tall fescue (Festuca arundinacea). Two groups 12 Angora does (initial average BW = 41.5 ± 2.7 kg) that previously grazed pasture crabgrass/tall for approximately 4 mo were used. After 1 wk adaptation metabolism cages, gas exchange measured 24 h in an open-circuit respiration...

Research was conducted to determine the effects of level supplementation with quebracho condensed tannins (CT) on in vitro ruminal fluid gas production, vivo protein fractions, bloat dynamics, and ADG steers grazing winter wheat. Two experiments were 1) enumerate effect from fed CT (0, 1, 2% CT/kg DMI) methane production minced fresh wheat forage; 2) quantify influence characteristics, biofilm complexes, potential, pasture. Eighteen ruminally cannulated (386 +/- 36 kg BW) randomly allocated...

Thirty-two primiparous and 31 multiparous Alpine goats were used to determine influences of diets varying in level source forage on performance early mid-lactation for 16 wk. Diets consisted 40%, 50%, 60%, 70% (designated as 40F, 50F, 60F, 70F, respectively) with 60F 70F containing coarsely ground grass hay (primarily orchardgrass) 40F 50F cottonseed hulls, alfalfa pellets, wheat hay. contained 15.9% 16.3% crude protein 37.8%, 42.1%, 53.5%, 55.4% neutral detergent fiber (NDF) 10.0%, 15.8%,...

Two methods for estimating the flow of microbial protein synthesized in rumen to duodenum were compared: one uses nucleic acids entering duodenum, and other allantoin excreted urine. Ten ewes fitted with cannulae, as well Foley catheters collection The experiment was carried out using two series treatments replications each. randomly divided into five groups, which assigned diets. (In second sheep excluded from diets received first series.) diets, differing energy content, follows: (1) low...

The aim of this study was to determine the effect winter wheat (Triticum aestivum L.) forage growth stage, allowance, time day, and commercial condensed tannins (CT) on steer bloat dynamics in vitro ruminal gas production. Twenty-six crossbreed steers (Angus x Hereford Salers; average initial BW = 194 +/- 26 kg) were used. Wheat allowances either 18 kg (high allowance) 6 (low DM/(100 BW.d). In each observation period, fresh samples hand-clipped ground level all pastures for nutrient...

Abstract Background Gastrointestinal nematode infection (GNI) is the most important disease affecting small ruminant industry in U.S. The environmental conditions southern United States are ideal for survival of pathogenic gastrointestinal nematode, Haemonchus contortus . Host genetic variation resistance to H. allows selective breeding increased animals. This selection process increases prevalence particular alleles sheep and goats creates unique patterns genome these species. aim this...

Twenty-four yearling Boer × Spanish wethers were used to assess effects of different forages, either fresh (Exp. 1) or as hay 2), on feed intake, digestibilities, heat production, and ruminal methane emission. Treatments were: Sericea lespedeza (SER; Lespedeza cuneata), a legume high in condensed tannins (CT; 20% 15% forage hay, respectively), 2) SER supplemented with polyethylene glycol (SER-PEG; 25 g/d), 3) alfalfa (Medicago sativa), low CT (ALF), 4) sorghum-sudangrass (Sorghum bicolor),...

Abstract Understanding ruminal microbiota and diet–host breed interactions under forage feeding conditions is essential for optimizing rumen fermentation improving feed efficiency in small ruminants. This study aimed to investigate the effects of different ratios condensed tannin-rich Sericea lespedeza (SL; Lespedeza cuneata) diets on changes host species (i.e., sheep goats). Katahdin (n = 12) Alpine goats at approximately 10 12 mo age were blocked by body weight (BW 30.3 25.5 kg,...
