This investigation research was performed to compare between Barki lambs and Barki kids in feed intake, nutritive value, digestibility, body weight gain, and some rumen and blood parameters when fed three different tanniniferous shrubs. The forage concentrate ratio in all groups was 60%:40%. The forages were Acacia saligna, Prosopis juliflora and Cassava (G1, G2, and G3 respectively). The results indicated that the total DM intake (g/h/d) was decreased in G2 compared with G1 and G3. The digestibility of dry matter (DM), crude protein (CP) and crude fiber (CF) were increased by goats compared with sheep, while nitrogen utilization was nearly similar between both species and the highest value was recorded with G3 vs. G1 or G2. The highest concentration of rumen fluid NH3-N and TVFA's were recorded with goats vs. sheep. Moreover, animals fed Acacia showed the lowest value in NH3-N and TVFA's than those fed Prosopis or Cassava. Feed conversion (g CP/kg gain) tended to decrease with goats vs. sheep. The measured blood parameters show slight differences due to the source of shrubs, where all levels were within the normal ranges. So, tanniniferous shrubs could have used without any adverse effect on intake, water utilization and growth performance which improves the economic return of raising sheep and goats under semi-desert conditions of the North-Western Coast in Egypt.

Several attempts made towards utilization of such low value or unpalatable halophytic plants through proper processing methods to improve their palatability and nutritional utilization. Under semi-arid area conditions, small ruminants fed on trees and shrubs such as Cassava and Acacia to solve the attendant problems of low productivity (El Shaer 2010 andEissa et al., 2015a). However, such trees and shrubs foliage are generally rich in anti-nutritional factors, particularly tannins (Makkar, 2003). Feeding a mixture of these fodder shrubs could minimize or overcome the problems of palatability and toxic effects (

“…Ammoniation is known to increase DMD and N content of various straws including wheat (Horton, 1981; Herrera-Saldana et al, 1982; Givens et al, 1988; Kondo et al, 1992), oat (Horton, 1981; Givens et al, 1988), and barley (Horton, 1981; Hadjipanayiotou, 1982; Dryden and Kempton, 1983; Givens et al, 1988). AFEX is an advanced ammoniation technology and has been shown to increase digestibility of crop residues, compared to traditional ammoniation, by cleaving the hemicellulose-lignin ester linkages, or lignin carbohydrate complexes more efficiently (Chundawat et al, 2010).…”

Fermentation of Ammonia Fiber Expansion Treated and Untreated Barley Straw in a Rumen Simulation Technique Using Rumen Inoculum from Cattle with Slow versus Fast Rate of Fiber Disappearance

et al. 2016

The purpose of this study was to determine the effect of rumen inoculum from heifers with fast vs. slow rate of in situ fiber digestion on the fermentation of complex versus easily digested fiber sources in the forms of untreated and Ammonia Fiber Expansion (AFEX) treated barley straw, respectively, using an artificial rumen simulation technique (Rusitec). In situ fiber digestion was measured in a previous study by incubating untreated barley straw in the rumen of 16 heifers fed a diet consisting of 700 g/kg barley straw and 300 g/kg concentrate. The two heifers with fastest rate of digestion (Fast ≥ 4.18% h-1) and the two heifers with the slowest rate of digestion (Slow ≤ 3.17% h-1) were chosen as inoculum donors for this study. Two Rusitec apparatuses each equipped with eight fermenters were used in a completely randomized block design with two blocks (apparatus) and four treatments in a 2 × 2 factorial arrangement of treatments (Fast or Slow rumen inoculum and untreated or AFEX treated straw). Fast rumen inoculum and AFEX straw both increased (P < 0.05) disappearance of dry matter (DMD), organic matter, true DMD, neutral detergent fiber, acid detergent fiber, and nitrogen (N) with an interactive effect between the two (P < 0.05). Fast rumen inoculum increased (P > 0.05) methane production per gram of digested material for both untreated and AFEX straw, and reduced (interaction, P < 0.05) acetate: propionate ratio for untreated straw. Greater relative populations of Ruminococcus albus (P < 0.05) and increased microbial N production (P = 0.045) were observed in Fast rumen inoculum. AFEX straw in Fast inoculum had greater total bacterial populations than Slow, but for untreated straw this result was reversed (interaction, P = 0.013). These findings indicate that differences in microbial populations in rumen fluid contribute to differences in the capacity of rumen inoculum to digest fiber.

“…These authors obtained, however, a slightly higher improvement in DM digestibility than we did. This may be because they used wheat straw, which is more responsive to ammoniation than barley straw [6].…”

-A control and three treatments of barley straw were compared: NH 3 (3% of dry matter (DM)), 3% NH 3 after rehydration of the straw to 15% moisture with water, and 3% NH 3 after rehydration to 15% moisture with a H 2 O 2 solution (0.32% of DM). Forages were fed to fistulated ewe lambs, with a supplement, at two levels of intake (ad libitum and 75% ad libitum). At the ad libitum intake, the treatments mainly improved the intake; and digestible DM intake was 336, 455, 501, and 552 grams per head per day for untreated, NH 3 , NH 3 + H 2 O, and NH 3 + H 2 O 2 -treated straws, respectively. The first, second, and fourth values were different from each other (P < 0.01), but the third one was not different from the fourth (P = 0.09). A similar trend was observed in most other nutrient utilization parameters and fermentation characteristics. Intake restriction raised DM digestibility from 56.9% to 58.2% (P = 0.04). Anhydrous ammonia cannot provide alkalinity for the optimal action of hydrogen peroxide. straw / treatment / ammonia / hydrogen peroxide Résumé -Métabolisme alimentaire de la paille d'orge traitée à l'ammoniac anhydre et/ou à l'eau oxygénée chez les agnelles. Un témoin et trois traitements de paille d'orge : NH 3 (3 % MS), 3 % NH 3 après réhydratation de la paille à 15 % d'humidité avec de l'eau, et 3 % NH 3 après réhy-dratation à 15 % d'humidité avec une solution de H 2 O 2 (0,32 % MS) ont été comparés. Ces pailles ont été distribuées, à 8 agnelles fistulées, à deux niveaux d'ingestion (ad libitum et 75 % ad libitum), selon un dispositif en carré latin. Lorsque l'ingestion était à volonté, les traitements ont agi principalement sur l'ingestibilité, et la MS digestible a été de 336, 455, 501, et 552 grammes par tête par jour pour le témoin, les pailles traitées à NH 3 , NH 3 + H 2 O, et NH 3 + H 2 O 2 respectivement. Les première, deuxième, et quatrième valeurs ont été significativement différentes l'une de l'autre (P < 0,01) ; alors que la troisième ne l'a pas été de la quatrième (P = 0,09). Une tendance semblable a été observée pour la plupart des autres paramètres de digestion. La digestibilité de la MS est passée, en moyenne, de 56,9 % à 58,2 % avec la restriction de l'ingestion (P = 0,04). L'ammoniac ne peut pas fournir une alcalinité suffisante pour une action optimale de l'eau oxygénée.paille / traitement / ammoniac / eau oxygénée Ann.
