“…This result is consistent with those of other studies (O'Kelly and Spiers, 1992;Nagaraja, 1995;Sauer et al, 1998;García-González, 2008b). When methane production is inhibited, a decrease in both acetate and butyrate and a concomitant increase in propionate production are expected (Van Nevel and Demeyer, 1992).…”

“…MO also favours propionate producing bacteria (Jalc et al, 1992;Newbold et al, 1993), which results in an increase in propionate production. Many studies including both in vitro and in vivo trials (O'Kelly and Spiers, 1992;Nagaraja, 1995;Sauer et al, 1998;García-González, 2008a,b) suggested that addition of MO reduced methane production, decreased acetate content and the acetate:propionate ratio, increased propionate content, and inhibited protozoa proliferation. Our results are in concordance with those of previous studies.…”

“…Reducing ruminal methane production could improve animal performance and decrease greenhouse effect. Monensin (MO) and other ionophores have been used to effectively manipulate ruminal fermentation and mitigate ruminal methane production (Spiers, 1992;Nagaraja, 1995;Sauer et al, 1998;García-González, 2008a,b). However, nowadays the public are more concerned about the use of antibiotics which may lead to health problems.…”

This study evaluated the effects of addition of lucerne extract (LE), Artemisiae annuae extract (AAE), and mixed herbal medicine (MHM) into different goat diets on in vitro rumen fermentation and methane production. In addition to the negative control (NC), addition of monensin (MO) served as the positive control (PC). Four ruminally cannulated Nanjiang Yellow goats (45 ± 2 kg liveweight) were used as donors of ruminal fluid. The results showed: 1. compared with NC, addition of all the additives into the mixed grass diet increased propionate concentration (P<0.05). Protozoa numbers and methane production were reduced by addition of all the additives (P<0.05); 2. compared with NC, LE and AAE in the lucerne diet increased propionate concentration (P<0.05). All the additives reduced protozoa numbers (P<0.05). Methane production was decreased by addition of LE compared with NC and PC (P<0.05); 3. addition of LE into the mixed grass-concentrate diet resulted in an increase of the propionate concentration compared with NC and PC (P<0.05). Protozoa numbers were reduced by addition of LE and AAE compared with NC (P<0.05). Methane production was decreased by addition of AAE compared with NC and PC (P<0.05); 4. compared with NC, addition of AAE and MHM into the lucerne-concentrate diet resulted in an increase of propionate concentration (P<0.05). Protozoa numbers were reduced by addition of all the additives (P<0.05). Methane production was decreased by addition of AAE and MHM (P<0.05).In conclusion, addition of LE, AAE and MHM into different diets reduced methane production, increased propionate concentration and decreased protozoa numbers to a certain extent, and the inhibitory effects of the phytogenic products on methane production are more remarkable in the mixed-grass diet. The phytogenic products appear to be promising alternatives to MO in altering in vitro rumen fermentation and reducing methane production in goats. 219 DONG G.Z. ET AL.

“…Antimicrobial feed additives can stabilize ruminal fermentation by promoting changes in microbial populations and their activity in the rumen, reducing the incidence of metabolic disorders, and improving rate and efficiency of growth (Nagaraja, 1995). The isolated utilization of ionophore, like monensin or salinomycin, or non-ionophore antibiotics, such as virginiamycin, as growth promoter feed additives has been thoroughly investigated.…”

Zebu cattle fed high concentrate diets may present inconsistent performance due to the occurrence of metabolic disorders, like acidosis. The isolated use of ionophores and virginiamycin in high grain diets can improve animal performance and reduce the incidence of such disorders, but recent studies suggested that their combination may have an additive effect.Thus, 72 Nellore steers, 389 ± 15 kg initial body weight (BW), were confined and fed for 79 days to evaluate the combination of virginiamycin and salinomycin on performance and carcass traits. Animals were allocated to a randomized complete block design by BW, in a 2 × 2 factorial arrangement of treatments, with two concentrate levels (73 and 91 %) and two virginiamycin levels (0 and 15 mg kg -1 ), and salinomycin (13 mg kg

Özet: Yem katkı maddesi olarak antibiyotik, hormon ve hormon benzeri maddelerin kullanımının yasaklanmasından sonra birçok araştırmacı çalışmalarında, bu maddelere alternatif olabilecek yem katkı maddeleri üzerine yoğunlaşmıştır. Bu amaçla son yıllarda sindirim sistemini düzenleyici, metabolizmayı değiştirici, fizyolojik dengeleri koruyucu ve diğer özellikte etkilere sahip yem katkı maddelerinin ruminantlarda kullanımı ön plana çıkmaktadır. Sindirim sistemini düzenleyici katkı maddeleri sindirim kanalında mikrobiyel gelişimi sağlamakta, patojen mikroorganizmaların zararlı hale geçmesini ve üremesini önlemekte, yemlerin sindirilme derecelerini artırmaktadır. Metabolizmayı değiştirici katkı maddeleri ise metabolizmayı direk ya da dolaylı olarak etkilerken, fizyolojik dengeleri koruyucu katkı maddeleri rumen fermentasyonunda meydana gelebilecek olumsuzlukları önlemektedir. Bu derlemede bu katkı maddelerinin ruminantlarda sağlık, verim performansı üzerinde oluşturduğu etkiler üzerinde durulmaktadır.Anahtar kelimeler: Ruminant, Verim performansı, Yem katkı maddesi. Feed Additives Effective on Productive Performance in RuminantsAbstract: In the last decade, many researchers have focused on feed additives as an alternative to antibiotics, hormones and hormon-like supplements, since the usage of those feed additives have been banned in animal feeding. Recently, the usage of feed additives as a digestive system regulatory agent, metabolism modifier and physiological balance protective come into prominence in ruminants. Feed additives regulating digestive system support the microbiologic development and prevent the colonization of pathological microorganisms or increase the digestion degree of feeds. Metabolism-altering feed additives affect the metabolism directly or indirectly, while the physiological protective feed additives prevent the deleterious effects in rumen fermentation. In this study, the effect of feed additives on health and yield performance was reviewed.
