“…cerevisiae with protease improved the growth performance and feed conversion ratio without affecting the DMI of lambs, but no significant differences were detected between the supplementation treatments. Our findings are in agreement with those of previous reports that probiotics supplementation and monensin were equally effective to increase the weight gain of lambs and no significant difference of DMI was detected 1 , 17 , 18 .…”

Alternatives to antibiotics for improving productivity and maintaining the health of livestock health are urgently needed. The scope of this research was conducted to investigate the effects of two alternatives (Bacillus licheniformis and Saccharomyces cerevisiae) to monensin on growth performance, antioxidant capacity, immunity, ruminal fermentation and microbial diversity of fattening lambs. One hundred and sixty Dorper × Thin-tailed Han sheep (32 ± 3.45 kg BW) were randomly assigned into 5 treatments of n = 32 lambs/group. Lambs in the control group were fed a basal diet (NC) while the other four treatments were fed basal diets supplemented with monensin (PC), Bacillus licheniformis (BL), Saccharomyces cerevisiae (SC), and the combination of Bacillus licheniformis and Saccharomyces cerevisiae with protease (BS), respectively. The experiment lasted for 66 d. Feed intake was recorded every 2 d and lambs were weighed every 20 d. Ten lambs from each group were slaughtered at the end of the trial, and samples of serum and rumen fluid were collected. The results indicated that the dietary regimen did not affect the dry matter intake (DMI). The average daily gain (ADG) of BS treatment was significantly higher than NC group (P < 0.05). Compared with the NC treatment, the other four supplementation treatments increased the concentration of growth hormone (GH), insulin-like growth factor I (IGF-I) and insulin (INS) (P < 0.05). The malondialdehyde (MDA) and total antioxidant capacity (TAOC) showed no significant difference among the 5 treatments while the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) of BS group was significantly increased (P < 0.05). The supplementation regimen decreased the concentration of ammonia Nitrogen (NH3-N) and increased the content of microbial crude proteins (MCP) (P < 0.05). The supplementation of antibiotics and probiotics reduced the concentrations of acetate and increased the concentrations of propionate (P < 0.05). The supplementation treatments increased the relative abundance of Lentisphaerae, Fibrobacteres and Tenericutes at the phylum level, whereas at the genus level, they increased the relative abundance of Fibrobacter (P < 0.05). Overall, this study confirmed the facilitating effect of B. licheniformis, S. cerevisiae and their compounds on growth performance, improve the antioxidant capacity and immune function, and beneficially manipulate ruminal fermentation and microbial diversity of fatting lambs.

“…However, probiotic or monensin supplemented diets decreased the concentration of acetate while the concentration of propionate and butyrate was increased. There are many reports of this change in the A:P ratio 17 , 30 , 31 . The VFA profile is associated with effects on end-product composition and energy balance in ruminants.…”

“…This increase in post-ruminal amino acid flow has also been reported by other researchers (Putnam et al 1997, Doreau andJouany 1998). However, Hernandez et al (2009) reported no effect of probiotic supplementation in N-retention, N-intake and faecal and urinary N in lambs fed mature orchard grass. Jouany et al (1998b) also reported no change in urinary N excretion in response to probiotic supplementation.…”

Small ruminants represent an important economic source in small farm systems and agriculture. Feed is the main component of livestock farming, which has gained special attention to improve animal performance. Many studies have been done to improve feed utilisation through addition of feed additives. For a long period, antibiotics have been widely used as growth promoters in livestock diets. Due to their ban in many countries, search for alternative feed additives has been intensified. Probiotics are one of these alternatives recognised to be safe to the animals. Use of probiotics in small ruminant nutrition has been confirmed to improve animal health, productivity and immunity. Probiotics improved growth performance through enhancing of rumen microbial ecosystem, nutrient digestibility and feed conversion rate. Moreover, probiotics have been reported to stabilise rumen pH, increase volatile fatty acids production and to stimulate lactic acid utilising protozoa, resulting in a highly efficient rumen function. Furthermore, use of probiotics has been found to increase milk production and can reduce incidence of neonatal diarrhea and mortality. However, actual mechanisms through which probiotics exert these functions are not known. Since research on application of probiotics in small ruminants is scarce, the present review attempts to discuss the potential roles of this class of feed additives on productive performance and health status of these animals.

“…Higher N balance in the present study may be due to comparatively higher DMI as well as higher N content and also increased ruminal N pool and post-ruminal amino acid flow (Thota et al, 2017). Contrary, Hernandez et al (2009) observed that Nintake, fecal-N, urinary N and N-retention were not affected in lambs fed with orchard grass hay as basal diet. The revealed NB values were nearly close to that found by Wang et al (2021) which ranged from 6.82 to 8.02 g/d for lambs fed diets based on sorghum fodder.…”

It was applied in two experiments (Agronomy and fodder evaluation experiment and animal growth experiment) to determine the response of sorghum quality and consequently the animal performance to the application of combined N and P fertilizer in newly reclaimed soil. The first experiment was for evaluating sorghum fodder (Sorghum bicolor L.) that sorted with nine treatment combinations (from T1 up to T9) comprising of three nitrogen (N) and phosphorus (P) fertilizers levels (N 80.4 , N 100.5 and N 120.6 kg/feddan vs. P 20.2 , P 30.2 and P 40.3 kg/feddan) in factorial randomized block design with three replications. The results of the agronomy experiment with considering the ISDMD, NEg and the cost of treatments, showed that two treatments (N 120 P 30 and N 100 P 40 ) could be nominated to the second experiment which was their evaluation as feeds for the growing Barki lambs as compared to control treatment (N 80 P 20 ). So, two treatments and control were sorting again in the next summer season to evaluate their nutritive values by using 15 growing Barki lambs (5 lambs/ treatment) in a completely randomized block design. Lambs were on average 22.83 ± 0.29 kg as the initial body weight and aged 5 months. All animals fed concentrate feed mixture to cover 70% of their growth requirements (Kearl, 1982). However, the experimental fodders were offered ad lib. So the experimental animal groups were allowed for three rations for 85d as follows; R1: CFM + sorghum forage of T1 (N 80 P 20 ) ad lib., (served as a control), R2: CFM + sorghum forage of T6 (N 120 P 30 ) ad lib, and R3: CFM + sorghum forage of T8 (N 100 P 40 ) ad lib. The results indicated that; Average daily gain differed significantly (P= 0.016) being values 158, 185 and 192g for lambs fed R1, R2 and R3, respectively. Animals in R2 and R3 consumed a higher (P=0.042) amount of sorghum compared with the control one. There is a significant effect (P< 0.05) of sorghum treatments on feed conversion ratio (FCR), where sheep fed R1 or R2 had better FCR as g DM/ g gain or g TDN/ g gain than those fed control sorghum ration. However, R1 revealed better FCR as g DCP/g gain as compared with the other groups. The digestibilities of DM, CP and CF were higher (P<0.05) for R2 and R3 compared to the control one. However, digestibilities of EE and NFE were not affected (P>0.05) by the experimental rations. Both R2 and R3 were the better (P<0.05) for both TDN and DCP values as compared with the control ration. Higher (P<0.05) N balance was observed with R2 than control. All lambs retained relatively similar (P>0.05) amounts of calcium. However, higher P content in sorghum of R2 and R3 revealed significantly higher P intake (P<0.05) and also P retained (P<0.05). The revealed insensible water loss (IWL) of the three groups was significantly different being values 144, 172 and 176 g/kg 0.82 for R1, R2 and R3, respectively. The rumen pH value of animal group fed control ration (R1) was significantly (P≤0.001) higher than other groups at all the sampling time. Animals who received R2...
