“…Fibre degradation in the rumen gets initiated by attachment of fibrolytic microbes with the feed particles, which is an essential pre-requisite (Akin, 1979;Morris and Cole, 1987). In an earlier experiment in our laboratory and results from the other laboratories, it has been shown that fibrolytic enzymes are maximum in the particulate fraction (partially digested fibrous feed particles in the rumen) (Williams et al, 1989;Huhtanen and Khalili, 1992;Agarwal et al, 2000;Ha et al, 2002). Similarly in the present experiment too it has been observed that major portions (>80%) of the total activity of fibrolytic enzymes were present in the particulate fraction, except protease which was absent in this fraction.…”

Feeding of animals and experimental designFour rumen fistulated Murrah buffaloes of body weight ranging from 180-242 kg, were fed four diets consisting of roughage (wheat straw) and concentrate mixture in the ratios of 80:20, 70:30, 60:40 and 50:50 respectively, in a 4×4 Latin Square design. Wheat straw and concentrate mixture, consisting of wheat bran 37, crushed maize grain 30, mustard seed cake 30, mineral mixture 2 and salt 1 parts, were mixed with water (0.6 l/kg feed) manually and offered to animals as complete feed mixtures at 8:00 h and 16:00 h in two equal parts. Each feeding period lasted 30 days, and the sampling of rumen liquor and rumen contents was done after 25 days of feeding for two consecutive days. The rumen liquor was collected at 0, 2, 4, 6 and 8 h post feeding. After recording pH the samples were pooled for the day

“…Hussein et al (1995), reported a lower dietary forage level was followed by a greater TAA concentration in the mixed ruminal bacteria. However, previous studies indicated that dietary Tween 80 supplementation appeared to increase the growth of noncellulolytic bacteria, but not of cellulolytic bacteria (Ha et al 2002;Goto et al 2003;Lee et al 2003). However, contrary to LQB, the differences were quantitatively minimal.…”

In the present study, the effects of different forage-to-concentrate ratios (F:C) and an alkyl polyglycoside (APG) supplementation on parameters of rumen and blood metabolism were investigated in goats. A 2 x 2 factorial experiment was arranged within a 4 x 4 Latin square design (four 22-day periods), using four wether goats equipped with permanent ruminal cannulas. The experimental diets included two F:C levels (40:60 vs. 60:40), and two APG supplementation levels (None or 13 ml APG daily per animal). Rumen contents and blood samples were collected at the end of each period. Dietary F:C alteration affected plasma urea and influenced the proportions of leucine, histidine, arginine, glycine, proline, alanine, valine, phenylalanine, cysteine and tyrosine in rumen content, and the proportions of methionine, threonine and proline in solid-associated bacteria (SAB) significantly. Dietary APG decreased the proportions of valine and phenylalanine in rumen content, and the histidine content of liquid-associated bacteria. The interaction between dietary F:C and APG was significant for the proportions of glycine and alanine in rumen content, and the proportions of lysine and threonine in SAB. The proportion of lysine was greater, but the proportion of threonine was less in SAB for goats fed high F:C diet without APG supplementation. The proportions of plasma free amino acids and glucose concentration were not affected by experimental treatments. These results indicated that dietary APG addition affected the amino acid composition of the rumen content and ruminal bacteria, but this depended on the dietary F:C ratio. It is necessary to validate the effectiveness of dietary APG supplementation in further studies with more animals.

“…It has been speculated that increasing milk fat content by NIS supplementation might be related to the influences of NIS on rumen microflora [20] since rumen fermentation products, such as acetate (a primary milk fat precursor) and butyrate, are used by the cow for energy and by the mammary glands to produce milk fat [23]. Moreover, NIS have been shown to have an impact on rumen fermentation and the rumen microbial population [6,24,25,26,27]. On the other hand, our previous study indicated that the proportions of ruminal amino acids, such as valine, phenylalanine and lysine, were affected by the dietary APG supplementation in goats [14].…”

This study evaluated the effects of alkyl polyglycoside (APG), which is a non-ionic surfactant, on lactation performance, nutrient digestibility and blood metabolites in dairy cows. Twenty dairy cows were randomly divided into four groups and fed a basal diet that included pelleted concentrate, distillers grains, and fresh limpograss. The four treatments included 0, 5.5, 11 and 22 mL APG per kg of pelleted concentrate on a dry matter basis; treatments were defined as APG0, APG5.5, APG11, and APG22, respectively. Dry matter intake was not affected by APG supplementation. There was an increase in milk yield (from 13.96 to 16.71 kg/day) and increases in milk fat (quadratic, p = 0.04), protein (quadratic, p = 0.10), and lactose concentrations (linear, p = 0.07) with increasing APG supplementation. In addition, APG supplementation increased (p ≤ 0.03) the milk fat, protein, solid non-fat, and total solid yields, while the lactose yield increased (linear, p = 0.01) as the APG level increased. Dietary APG supplementation had no effect on nutrient digestibility and blood metabolites. It was concluded that the addition of APG at doses up to 22 mL/kg of pelleted concentrate had positive effects on the milk composition in dairy cows.
