“…This may be because ruminants have the ability to adapt to the consumption of plants with high content of secondary compounds such as S. babylonica, or EZ addition that improved ruminal microorganisms activities with increasing the time of feeding diets with EZ until 60 days (Salem et al, 2011b). Other haematological parameters such as white blood cells, segmented neutrophils, lymphocytes, basophils and eosinophils were not affected by the sampling time.…”

“…The S. babylonica extract was prepared as described by Salem et al (2011b). Briefly, fresh leaves of S. babylonica were collected randomly from several young and mature trees (minimum 5 different trees) in autumn and were chopped (1-2 cm) and immediately extracted in the proportion of 1 g leaf per 8 ml of solvent mixture.…”

“…Plant extracts rich in secondary compounds have been shown to have positive effects on daily gain, voluntary feed intake, milk production and ruminal fermentation parameters (Salem et al, 2011b), besides having a protective effect on the protein in the rumen to promote duodenal absorption, minimizes the excretion of nitrogen, modify the acetate to propionate ratio in rumen fluid and decrease parasitic load (Athanasiadou and Kyriazakis, 2004;Salem et al, 2010;Jiménez et al, 2011). Although, the use of plant extract could be limit by their secondary compound concentrations, consumption of large amounts of tannins or saponins (Athanasiadou and Kyriazakis, 2004) may have a direct haemolytic effect and may even cause death.…”

The aim of this study was to compare the use of exogenous enzyme preparations (EZ) and/or Salix babylonica extract (SB) or their combination as feed additives on some haematological parameters in growing lambs. Twenty Suffolk lambs of 6 to 8-months-old with 24±0.3 kg body weight were used in the study. Lambs were divided into 4 groups of 5 animals each in a completely randomized design and the treatments were: 1.control: fed a basal diet of concentrate (30%) and maize silage (70%); 2. EZ: fed the basal diet plus 10 g of enzyme; 3. SB: fed the basal diet plus 30 ml of S. babylonica extract, and 4. EZSB: fed the basal diet plus 10 g enzyme and 30 ml of S. babylonica extract. Lambs were housed in individual cages and the experiment was conducted for 60 days. The SB was given orally while the EZ was mixed with a small amount of the concentrate and maize silage and was offered ad libitum. Blood samples were collected from each animal on days 0, 15, 30, 45 and 60 of Animal and Feed Sciences, 21, 2012, 577-586 ENZYMES -HAEMATOLOGICAL PARAMETERS IN LAMBSexperiment and analysed for haematological parameters. The treatments of EZ, SB or EZSB did not affect any of the measured blood parameters. Day of sampling modified concentrations of red blood cells (P=0.001; linear effect), haematocrit (P=0.01; quadratic effect), haemoglobin (P=0.01; linear effect), mean corpuscular volume (P=0.01; linear effect), monocytes (P=0.004; quadratic effect) and plasma protein (P=0.0002; linear effect). It could be concluded that Salix babylonica extract, exogenous enzymes and their combination as feed additives had not a negative effects on the blood parameters measured and therefore on the health of the lambs.

Inclusion of dried citrus pulp (DCP) at different levels: 0 (control), 10% (DCP10), 20 (DCP20), and 30% (DCP30) of the total mixed ration (TMR) was evaluated by in vitro gas production (GP), and ruminal fermentation patterns, in a completely randomized design. Rumen fluid was collected before the morning meal from 8 gestating goats (Boer×Saanen, body weight 3±2.3 kg). GP was recorded at 2, 4, 6, 8, 10, 12, 24, 48, 72, and 96 h of incubation. Ruminal fermentation parameters such as 96 h partitioning factor (PF 96 ), in vitro organic matter digestibility (IVOMD), metabolizable energy (ME), short-chain fatty acids (SCFA), and metabolizable energy (ME) were also estimated. Inclusion of DCP linearly increased (P<0.01) cumulative gas production at 24, 48, and 96 h after inoculation, as well as asymptotic gas production (b). Rations at 30% and 10% DCP had the highest values of gas production, whereas control and 20% DCP presented the same values (quadratic effect P<0.01). Lag phase (L) decreased linearly (P<0.001) with DCP addition. IVDMD and IVOMD 7 Corresponding author: e-mail: asalem70@yahoo.com Journal of Animal and Feed Sciences, 21, 2012, 458-467 459 HERNÁNDEZ J. ET AL.increased linearly (P<0.01) with the inclusion of DCP in rations. The ration at 30% DCP (DCP30) had the greatest value of ME and SCFA, but no differences were observed in the PF 96 among treatments. The data suggest that the DCP30 ration had the best impact on rumen gas production and IVDMD, IVOMD, ME, and SCFA.

“…Likewise, Salem et al (2014) reported that influence of plant extracts with some active components result higher PF. From these above experiments, we may expect that the administration of plant extracts to ruminants will enrich the animal performance in favor of animal production and envirnomental impacts (average daily gain, SALEM et al, 2011;methane reduction, PATRA et al, 2006).…”

Research is never the effort of a single individual and it is a team work and many have put their effort in several ways to bring this thesis to completion. and degraded neutral detergent fiber (DNDF), especially LL, which had most influence on these parameters compared to other tannin containing plants. LL had positive response on antimethanogenic effects; its nutrient degradability was higher than that of other tannin containing plants. The second study (Expt. 2) was set to evaluate the effect of different organic extracts from the whole plant methanolic extract (MHE) of LL on in vitro gas production and to characterize the chemical constituents by using gas chromatography coupled with mass spectroscopy (GC-MS). Major abundant compounds present at the relative percentages of MHE were found to be stigmasterol trimethyl ester (TMS), neophytadiene, palmitic acid TMS, α-Linolenic acid TMS and 2, 3, 5, 6-tetra methyl anisylbenzene. The effects of additions of different extracts in terms of nutrient degradability (TDOM and DNDF) were increased by all extracts. This study explained that the methanolic hexane extract and methanolic chloroform extract was effective against methanogenic activity. The objective of the third study (Expt. 3) was to study the effect of LL plant leaves on rumen fermentation, apparent nutrient digestibility, nitrogen balance and methane production in Santa Ines sheep. The animals were divided in three groups in which they were fed with (i) 88% Tifton 85-hay (Cynodon spp.) and 12% soyabean meal (Control group, n=4); (ii) 28% Tifton 85-hay (Cynodon spp.) and 72% LL plus 20 ml solution containing 10g/day/animal of PEG (With PEG group -WPEG, n=6); (iii) 28% Tifton 85-hay (Cynodon spp.) and 72% LL plus 20 ml of distilled water (without PEG group-WOPEG, n=6). Nutrient intake (dry matter, organic matter, acid detergent fiber, lignin and crude protein) were higher in WPEG and WOPEG compared to the control group, except neutral detergent fiber intake. Apparent digestibilities and nitrogen metabolism had non-significant effects between the treatments. However, CH4 emissions were significantly lower in WPEG and WOPEG than the control. Furthermore, expressions of microbial populations of methanogens in WPEG had lower tendency than that of WOPEG and control. The most salient findings of this study were that, 72% LL plant leaves using in small ruminants diets increased animal productivity, we can get more benefits in terms of replacing the source of protein in the...
