| 1 | Direct-fed microbes: A tool for improving the utilization of low quality roughages in ruminants显示文摘For many years, ruminant nutritionists and microbiologists have been interested in manipulating the microbial ecosystem of the rumen to improve production efficiency of different ruminant species. Removal and restriction of antibiotics subtherapeutic uses from ruminant diets has amplified interest in improving nutrient utilization and animal performance and search for more safe alternatives. Some bacterial and fungal microorganisms as a direct-fed microbial(DFM) can be the most suitable solutions. Microorganisms that are commonly used in DFM for ruminants may be classified mainly as lactic acid producing bacteria(LAB), lactic acid utilizing bacteria(LUB), or other microorganism's species like Lactobacillus, Bifidobacterium, Enterococcus, Streptococcus, Bacillus, Propionibacterium, Megasphaera elsdenii and Prevotellabryantii, in addition to some fungal species of yeast such as Saccharomyces and Aspergillus. A definitive mode of action for bacterial or fungal DFM has not been established; although a variety of mechanisms have been suggested. Bacterial DFM potentially moderate rumen conditions, and improve weight gain and feed efficiency. Fungal DFM may reduce harmful oxygen from the rumen, prevent excess lactate production, increase feed digestibility, and alter rumen fermentation patterns. DFM may also compete with and inhibit the growth of pathogens, immune system modulation, and modulate microbial balance in the gastrointestinal tract. Improved dry matter intake, milk yield, fat corrected milk yield and milk fat content were obtained with DFM administration. However, the response to DFM is not constant; depending on dosages, feeding times and frequencies, and strains of DFM. Nonetheless, recent studies have supported the positive effects of DFM on ruminant performance. | Mona M Y Elghandour Abdelfattah Z M Salem Jose S Martínez Castaeda Luis M Camacho Ahmed E Kholif Juan C Vázquez Chagoyán | 2015 | Journal of Integrative Agriculture2015，14，3： | 7 |
| 2 | Effects of exogenous enzymes, Lactobacillus acidophilus or their combination on feed performance response and carcass characteristics of rabbits fed sugarcane bagasse显示文摘The aim of this study was to evaluate the effect of Lactobacillus acidophilus(LAC), exogenous enzymes of ZAD(exogenous enzyme preparation) or their combination on feed conversion, and dressing of rabbits fed different treatments of sugarcane bagasse(SCB). Five rations were allotted randomly to five groups of New-Zealand White(NZW) rabbits(n=10) with initial live body weight of(838±42.4) g and 5 weeks of age. Rabbits were fed on diets with different sources of fiber as follows,(i) a control diet composed of 100% berseem hay and 0% SCB,(ii) 50% berseem hay and 50% untreated SCB(USCB),(iii) 50% berseem hay and 50% SCB treated with L. acidophilus(LAC),(iv) 50% berseem hay and 50% SCB treated with ZAD(ZAD), and(v) 50% berseem hay and 50% SCB treated with a combination of LAC+ZAD(LZ). Treatments of SCB with L. acidophilus, ZAD and LAC+ZAD had the highest feed conversion ratio than both USCB and control. The dressing percentage of rabbits that fed the LAC and LZ diets was higher(P<0.05) compared with that in the other groups. Performance index(PI) for LAC group was improved(P<0.05) compared to that for the other groups; however, PI for USCB group was the lowest(P<0.05). It could be concluded that treating SCB with L. acidophilus, exogenous enzymes of ZAD or their combination improved feed conversion and performance with more positive effects with L. acidophilus than the other treatments. | Nahla A Abdel-Aziz Mounir El-Adawy Maria A Mariezcurrena-Berasain Abdelfattah Z M Salem Jaime Olivares-Pérez Ahmed E Kholif Borhami E Borhami | 2015 | Journal of Integrative Agriculture2015，14，3： | 5 |
| 3 | Biological treatments as a mean to improve feed utilization in agriculture animals——An overview显示文摘As a result of agriculture practices, million tons of agriculture are produced as a secondary or by-products; however, with low nutritive values. Many methods are applied to improve the nutritive value and increase its utilization in ruminant's nutrition. The biological treatments are the most common with more safe-treated products. In most cases, the biological treatments are paralleled with decreased crude fiber and fiber fractions content with increased crude protein content. Direct-fed microbial and exogenous enzymes to animal are other ways of biological methods for improving nutritive value of feeds. Here in this review, we will try to cover the biological treatments of by-products from different sides view with different types of animals and different animal end-products. | Nahla A Abdel-Aziz Abdelfattah Z M Salem Mounir M El-Adawy Luis M Camacho Ahmed E Kholif Mona M Y Elghandour Borhami E Borhami | 2015 | Journal of Integrative Agriculture2015，14，3： | 4 |

| 12 | Oral administration of Sauce llorón extract to growing lambs to control gastrointestinal nematodes and Moniezia spp.显示文摘Objective: To explore anthelmintic effects of oral administration of aqueous extract of Sauce llorón(Salix babylonica; SB) against gastrointestinal nematodes and Moniezia spp. Methods: Sixteen Pelibuey male lambs of 3-4 months of age and(23.7±3.3) kg body weight were used in a completely randomized design to be fed a total mixed ration(Control; SB0), or Control plus SB extract using 20(SB20), 40(SB40) and 60(SB60) mL/lamb/day for 45 days. Lambs had a natural gastrointestinal nematodes and Moniezia spp. infection and had never been treated with chemical anthelmintic drugs. Individual faecal samples were collected for ova counting using Mc Master procedure after 0, 7, 14, 21, 30 and 45 days post extract administration. Results: No extract dose×day interactions for both gastrointestinal nematodes and Monieziaspp. egg count were found. Administration of SB extract had a higher effect(quadratic effect, P=0.0064) at dose of 20 mL SB/lamb/day for gastrointestinal nematode eggs during the first 21 days; however, the dose of SB40 tended(linear effect, P=0.0897) to be more effective than the others for Moniezia spp. egg during the first 7 days. Sampling day had a linear(P=0.0436) effect on Moniezia spp. egg count. Conclusions: The aqueous extract of SB could be more effective against nematodes at 20 and at 40 mL/lamb/day for Moniezia spp. The use of the SB extract could represent a promising alternative to synthetic anthelmintics for the treatment of gastrointestinal nematodes and Moniezia spp. in small ruminants from organic and conventional production systems. | Cedillo J Kholif AE Salem AZM Elghandour MMY Vázquez JF Alonso MU Barbabosa A Chagoyán JCV Reyna AG | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，7： | 0 |
