“…This value is relatively greater than the lignin content of Gliricidia leaves (12.19%) (Ahmed et al, 2018) and of Napier grass (13%) (Liong et al, 2013), the two forages with the greatest DM effective degradability in the present study. Like tannin, lignin limits the DM degradability of feed materials because of the cross-linking of this compound with the other cell wall polysaccharides (Niwińska, 2012;Moreira et al, 2013). Gliricidia has a relatively low tannin content (Ahmed et al, 2018) which is why it has the greatest (P < 0.001) calculated ED together with Napier grass.…”

Two experiments, namely the situ nylon bag technique and the in vitro gas production technique, were carried out to determine the correlations between the in situ ruminal degradability and the in vitro gas production of different forages, and to predict the ruminal degradability of the forages using the gas production parameters. Forage samples from Napier grass (Pennisetum purpureum), Guinea grass (Panicum maximum), Para grass (Brachiaria mutica), Leucaena (Leucaena leucocephala), Rain tree (Samanea saman), and Gliricidia (Gliricidia sepium) were incubated in the rumen of three rumen-cannulated buffaloes using the in situ nylon bag technique for 3, 6, 12, 24, 48, and 72 h. The six forage samples were also subjected to the in vitro gas production analysis following the modified methods developed by Menke & Steingass (1988), along with 30 other commonly used forages in the Philippines. Both experiments followed a randomized complete block design. Their dry matter (DM), organic matter (OM), neutral detergent fiber (NDF), and crude protein (CP) degradation kinetics and effective degradability (ED) as well as the gas production parameters were then estimated. Results revealed that the ED of each nutrient was found to be moderately to strongly correlated with some of the gas production times and estimated gas parameters. The predictor models generated using the gas production parameters for the ED of DM, OM, and NDF were sufficiently strong (R 2 = 0.740, p value= 0.0002; R 2 = 0.659, p value= 0.0009; and R 2 = 0.813, p value < 0.0001, respectively) while that of CP was only moderate (R 2 = 0.500, p value= 0.0055). It was concluded that the relationship between the two techniques is sufficiently strong and therefore the gas production parameters can be used to predict the in situ ruminal nutrient degradability of forages.

“…Ruminants digestive system is characterized by functional and anatomical adaptations that allow food energy in fibrous plant material to be extracted, mainly energy from cellulose and others stubborn carbohydrates. Ruminant animals derive about 70% of their metabolic energy from microbial fermentation (Niwińska, 2012). An extensive fiber digestion in rumen leads to a higher supply of energy for animal and increases feed efficiency.…”

Red ginger is herb that commonly used as part of traditional medicine due to its essential oil content. Some essential oil have proven as rumen fermentation modifier. Addition of red ginger in ruminant diet was studied using in vitro gas production technique to evaluate its effect on nutrient digestibility. Red ginger meal was added to meet essential oil level in fermentation medium of 0 mg/l as control, 25, 50, 75 and 100 mg/l. The diet consisted of Penisetum hybride, rice bran, wheat pollard in ratio 60:20:20 DM basis. Feed fermentation was incubated for 24 h at 39°C. At the end of incubation data of gas production volume was taken, and residual feed were collected for further nutrient analysis to calculate the digestibility of dry matter (DM), organic matter (OM), crude protein (CP) and crude fiber (CF). Variance analysis was used to analysis collected data, followed by DMRT analysis. Addition of red ginger increase total volume of gas production at level 50 mg/L and above. DM and OM digestibility did not affected by red ginger addition whereas CP digestibility were significantly decreased start at level 50 mg/l. In contrast, CF digestibility of treatment level of 50 mg/l significantly higher than control. In conclusion, addition of red ginger correspond to level essential oil of 50 to 100 mg/l improve ruminal nutrient fermentation.

Animal nutrition and feed science are the main scientific promote for today's modern breeding and feed industries. Animal nutrition is the most important factor affecting performance, reproduction and products quality. Improving productivity through better nutrition is determined by some interrelated considerations such as the availability of nutrients, type of feeding system and the level of feeding management. Poor nutrition affects growth, reproduction and immune system. Besides, feed has financially the largest share in animal production, irrespective of species and production system. Feed accounts for 65-75% of total cost of livestock production. This chapter provides the fundamental concepts of animal nutrition a general awareness on nutrition and feeding of livestock (swine, poultry, beef and dairy cattle, sheep and goat). Besides, feed is financially the single most important element of animal production in most production system.
