Abstract The current study evaluated the effects of in-feed administration of thyme, celery or their mixture (as an alternative to salinomycin ionophore) on feed utilization and growth performance of Barki lambs. Fifty-five lambs weighing 18.5 ± 1.1 kg and about 90 ± 5 days old were stratified into 5 treatment groups and fed: (1) a control diet of concentrates and corn stover (60:40, on dry matter basis), or the control diet supplemented with (2) 15 g of thyme, (3) 15 g of celery, (4) 15 g of thyme and celery mix, or (5) 1 g of salinomycin/lamb daily for 288 days. Additives increased (P < 0.05) both corn stover and total intakes, while thyme and thyme/celery mix increased nutrient digestibility (P < 0.05) compared with the control treatment. Celery, thyme/celery mix and salinomycin treatments decreased serum cholesterol. Celery increased (P < 0.05) final body weight, weight gain and average daily gain without affecting shrunk liveweight, hot carcass weight or dressing percent. Thyme/celery mix increased fat thickness (P < 0.001), while thyme, celery and thyme/celery mix treatments increased (P = 0.001) the ribeye area. Salinomycin, celery and thyme treatments increased (P < 0.05) the lean proportion and decreased the fat proportion. Thyme, celery and thyme/celery mix treatments decreased (P < 0.001) carcass protein, while thyme and thyme/celery treatments increased (P = 0.001) carcass water holding capacity. Salinomycin, thyme and celery treatments decreased (P = 0.002) meat brightness score, while celery treatment increased (P < 0.05) redness of meat, without affecting yellowness, chroma or hue of the meat. Results in the present showed that these natural additives are comparable to salinomycin but further studies are necessary to validate the results and their mechanism of action.

Background: The effects of the probiotics vary with the doses and strains used for this reason, a study was conducted over 35 days to determine the effect of live yeast supplementation in the diet of growing rabbits on growth performance and apparent nutrient digestibility.Methods: A total of 60 New Zealand and California rabbits (5 weeks old, average body weight 0.881±0.015 kg) were housed in 30 cages. They were fed with a control diet based on alfalfa and maize or barley grains and supplemented with Procreatin®7 (Saccharomyces cerevisiae CNCM I 1077) or Biosaf® SC47 (Saccharomyces cerevisiae NCYC Sc47) at three doses, namely 0, 6.4, or 12.8 ×109 CFU per kg basal diet.Result: The higher yeast concentration had a positive effect (P less than 0.01) on final body weight (BW), average daily gain (ADG) and carcass weight (CW). However, there were no significant differences in dry matter intake. As a result of this, the feed conversion ratio (FCR) decreased (P less than 0.01). Significant increases (P less than 0.05) in nutrient digestibility (DM, OM, NDF and ADF) were observed with both grains. The use of yeast in maize and barley-based diets of rabbits has positive effects on growth performance and nutrient digestibility.

Abstract An experiment was executed to determine the effects of replacing wheat straw with corn stover on growth performance, behavioural characteristics, blood metabolites and nutrient digestibility in Beetal bucks. A total of twenty four Beetal bucks were assigned randomly to one of three treatment groups, having eight animals each, for 15 weeks experimental period. The dietary treatments included conventional (25% wheat straw and 75% concentrate), corn stover 50 (Fifty percent of wheat straw (12.5%) was replaced with corn stover, and corn stover 100 (Wheat straw was completely replaced with corn stover). Dietary replacement of wheat straw with corn stover has resulted in an increased dry matter intake and average daily gain by 10 and 26%, respectively in the bucks. Rumen pH and fecal score, however, remained unaffected by dietary replacement of wheat straw with corn stover in the bucks. The replacement of wheat straw with corn stover has resulted in an increased feeding and rumination time, improved lying time and length and decreased number of bouts in the bucks. Blood glucose, urea, bilirubin and calcium levels were remained unaffected by replacing wheat straw with corn stover. The blood phosphorous level, however, was decreased in bucks fed corn stover based ration. The bucks fed corn stover based ration has resulted in an increased digestibility of nutrients including organic matter, crude protein, neutral and acid detergent fiber compared to those fed wheat straw based total mixed ration.

Conventional feed resources for livestock are increasingly becoming more expensive, due to competition with man; hence nutritionists are searching for cheaper, locally-available alternatives. A total of forty-five (45) mixed sex weaner rabbits, aged 5 – 6 weeks, with average initial weights of between 694.42 and 761.10 g were used to investigate the effect of varying levels of cowpea milling waste (CMW) diets on their growth performance and nutrient digestibility. They were randomly allotted to five dietary treatments with nine rabbits per treatment. The control treatment (T1) contained 0 % CMW while treatments T2, T3, T4 and T5 had 10, 20, 30 and 40 % CMW dietary inclusion levels, respectively. Clean water and feed were offered ad libitum daily to the rabbits, and record of their feed intake and growth performance were taken for 12 weeks. At the end of the 11th week, a nutrient digestibility trial was carried out. Results show that there were no significant (P>0.05) differences in final body weight, body weight gain, total feed intake and mortality among the dietary treatments. Feed conversion ratio (FCR) for diets T4 (6.65) and T5 (6.66) containing 30 and 40 % CMW respectively, were as good as that of the control diet (6.11). Dry matter and crude protein digestibility showed no significant (P>0.05) difference across the treatments. Digestibility of crude fibre (72.64, 80.16, 84.04 and 80.90 % for T2, T3, T4 and T5 respectively), ether extract (95.98, 94.90, 96.04 and 94.38 % for T2, T3, T4 and T5 respectively), nitrogen free extract (94.30, 95.18, 93.58 and 94.90 % for T2, T3, T4 and T5 respectively), as well as total digestible nutrient (83.69, 76.11, 81.67 and 80.02 % for T2, T3, T4 and T5 respectively) of the test diets compared favourably with that of the control diet (72.94, 95.23, 96.04 and 80.47 % for CF, EE, NFE and TDN respectively). Hence, it can be concluded that CMW can be used safely as a protein source and included up to 40 % in weaner rabbit diets with no detrimental effect on their growth performance and nutrient digestibility.

Wheat Germ Oil

Vegetable oils are a source of natural antioxidants, including tocopherols, sterols, phenolic compounds, coenzymes, and polyunsaturated fatty acids that provide nutritional value, organoleptic properties, and significantly delay or prevent lipid oxidation. Eighty-four V-line rabbits at 5 weeks of age with an initial body weight (BW) of 535.60 ± 13.48 g were assigned randomly to four experimental groups (seven replicates in each group with three rabbits each). The first group served as a control and received 0.3 mL/kg BW of distilled water (CON), while the second and third groups received 0.3 mL/kg BW of rocket seed oil (RSO) and wheat germ oil (WGO), respectively. The fourth group received a mixture of oils consisting of 0.15 mL of RSO and 0.15 mL of WGO/kg BW (MOs). The experiment lasted 7 weeks. The study investigated the effects of RSO, WGO, and their mixture on growth performance, feed utilization, antioxidant status, and immune response of growing rabbits. The results indicated that the rabbits that were administered orally with RSO and WGO or their mixture had higher (p ≤ 0.05) final BW, weight gain, and average daily gain when compared to the control group. In addition, the feed conversion ratio improved significantly with RSO, WGO, and MOs treatments. Different oil treatments improved nutrient digestibility, nutritive value, and nitrogen balance. Moreover, the rabbits that received RSO, WGO, and their mixture had an improvement the meat fatty acid composition compared to the control rabbits. Oral administration of RSO, WGO, and their mixture significantly improved serum protein fractions, decreased blood urea nitrogen, and had a positive effect on serum total lipids, HDL-c, and LDL-c. Furthermore, the treatments of RSO, WGO, and MOs had a significant improvement in the antioxidative status and immune response.

The purpose of this study was to evaluate the effects of dietary supplementation of Quillaja saponin (QS) on growth performance, nutrient digestibility, fecal microbiota, and fecal gas emission in growing pigs. A total of 50 crossbred growing pigs [(Yorkshire × Landrace) × Duroc] with an initial body weight of 23.83 ± 1.95 kg were randomly assigned to 1 of 2 treatments for a 56-day trial with 5 replicate pens per treatment and 5 pigs (2 barrows and 3 gilts) per pen. Dietary treatments including control diet and control diet supplemented with 200 mg/kg QS. The average daily gain was significantly increased during days 0-56, while the fecal ammonia emission on day 56 and fecal coliform bacteria counts on day 28 were significantly decreased in pigs fed with QS containing diet. However, dietary supplementation of QS had no significant effects on apparent total tract digestibility. In conclusion, dietary supplementation of 200 mg/kg QS had beneficial effects on growth performance, fecal microbiota, and fecal gas emission in growing pigs. Considering the carry-over effects, the adaption period should be at least 28 days when supplementing 200 mg/kg QS to the diet of growing pigs for improving the growth performance.

Purpose The purpose of this study was to investigate the effect of a dietary probiotic on the growth performance and survival rate of Litopenaeus vannamei shrimp. Furthermore, the microbial quality of shrimp was evaluated. Design/methodology/approach Shrimp were divided into treatment and control groups (each group containing 45 shrimp). They were fed for four weeks with a control diet alone or supplemented with a commercial probiotic (Protexin®). At the end of the trial, they were assessed for survival rate, weight gain, average daily gain and specific growth rate. Samples of tail meat were also provided aseptically from peeled shrimp for bacteriological analysis including the count of Staphylococcus aureus, enterococci, Clostridium perfringens, fecal coliform, Salmonella, Escherichia coli, Listeria monocytogenes and total bacterial count. Findings The growth performance of the probiotic-treated group significantly (p < 0.05) increased at the end of the experimental period. However, no significant differences were observed for the survival rate between the groups (p > 0.05). The count of C. perfringens and the total bacterial count in shrimp supplemented with the probiotic were significantly lower than those of controls (p < 0.05). The count of coliforms and S. aureus was not significantly different between the groups (p > 0.05). Originality/value It could be concluded that the probiotic bacteria have the potential to stimulate the growth performance of L. vannamei. They can also be used for biological control of food-borne pathogens and improve the microbial quality and safety of shrimp at the farm level.

Background: This study was conducted to evaluate the effects of different levels of citric acid (CA) on the growth performance, nutrient digestibility and gastrointestinal pH of weaned piglets. Methods: A total of 120 weaned piglets with an initial BW of 7.15±0.01 kg, were randomly divided into four groups including control treatment each with three replicates of 10 piglets each. Each group was supplemented with 0.5% (control group), 1%, 1.5% and 2% CA in the basal diet, respectively. Result: The results showed that the average daily feed intake (ADFI) and average daily gain (ADG) of added 1% CA group were significantly higher than that of 0.5% group (P less than 0.05). Dietary CA significantly improved the utilization rates of crude protein, calcium and phosphorus (P less than 0.05), while there was no significant difference between adding 1% and 1.5% CA (P greater than 0.05). Compared with the control group, adding CA effectively reduced the pH of the stomach, duodenum jejunum and ileum contents and adding 2% CA were significantly lower than those in other groups (P less than 0.05). Therefore, the addition of 1.0% CA in the diets of weaned piglets is suitable.

A 56-day feeding trial was performed to examine the effects of using Nymphaea lotus leaf meal (NLM) on growth performance, feed utilization, body composition, and survival rate of African catfish (Heterobranchus longifilis). Five treatment groups in triplicates with an average of the initial weight of 0.26±0.07g were fed diets incorporated with graded levels of NLM (0, 10, 20, 30 and 40%). The obtained results showed that higher final body weight (FBW), daily weight gain (DWG), and specific growth rate (SGR) were observed with fish fed the control diet (CD) and NLM at the level of 20% compared to those of fish fed other diets. Protein efficiency ratios (PER) were not altered with dietary treatment. In addition, feed conversion ratio (FCR) of fish groups fed up to 30% of NLM were not varied (p>0.05), meanwhile, daily feed intake of fish fed NLM diets exhibited lower values compared to those of fish fed CD. Final whole body proximate compositions of catfish showed no significant differences (P>0.05) except for the body total fat and ash contents. Fat contents of fish fed diets incorporated with NLM were significantly lower than those of fish fed the control diet (CD) (P<0.05). Meanwhile, ash contents of fish fed diets incorporated with high levels of NLM (30, 40%) were significantly lower than those of fish fed the control diet (CD) (P<0.05). Survival rates ranged between 72 - 80% and there were no differences among all groups (P > 0.05). Therefore, the results of the present study suggest that up to 20% of NLM protein can be incorporated in the diet of African catfish with no adverse effects on growth performance, feed utilization, and survival rate.

A nutrient retention and growth performance study were conducted with broiler chicks to evaluate the effect of different duration of fermented baobab seed meal (FBSM). Fermented baobab (Adansonia digitata) seeds were ground and incorporated in the diets at 12% dietary level. Diet 1 (control diet) had no BSM. Diet 2 had unfermented BSM. Diets 3, 4 and 5 had baobab seed meal (BSM) fermented for 48 h, 72 h and 96 h, respectively. Two hundred and forty (240) Arbor Acre chicks at one-week old were weighed and distributed to these dietary treatments. The five (5) treatments were replicated four (4) times in a completely randomized design, with 12 birds per replicate (48 per treatment). The diets did not significantly (p>0.05) influenced Feed intake, final body weight, feed conversion ratio and protein intake across treatments. The body weight gain and protein efficiency ratio of the chicks fed 96 h fermented BSM were not significantly (p>0.05) different with those fed control diet but were significantly (p<0.05) higher than chicks of other treatment groups. Starter broiler chicks fed T4 had significantly (p<0.05) higher nutrient digestibility parameters across treatments, except for EE and CF that were highly digested by chicks fed T3 and T1 respectively. In conclusion the performance of broiler chicks fed 96 h FBSM competed favorably with those fed control diet, whereas, chicks placed on 72 h FBSM recorded better result of nutrient digestibility.

A total of 125 crossbred pigs with an initial body weight (BW) of 7.66 ± 1.30 kg were randomly distributed into one of five dietary treatments. Each treatment had five replicate pens with five pigs per pen. Treatments were as followed: (1) CON, control diet; (2) zinc oxide (ZO), CON + 0.3% ZO; (3) ZOM, CON + 0.3% ZO + 0.1% microencapsulated organic acids and pure botanicals (MOP); (4) microencapsulated zinc oxide (MZO), CON + 0.03% MZO; and (5) MZOM, CON + 0.03% MZO + 0.1% MOP. The MZO group had higher (P = 0.03) final BW than ZO group and also had higher (P = 0.04, 0.01) average daily gain and gain/feed ratio compared with ZO group during days 15–34 and throughout the experimental period. The MZO and MZOM had higher (P < 0.05) apparent total tract digestibility (ATTD) of dry matter (DM) and energy than ZO. Less (P < 0.05) feces Escherichia coli shedding was observed in the ZOM and MZOM diets compared with CON; the MZO had lowered (P = 0.001) zinc level in feces than ZO and CON. In conclusion, results indicated that supplementation with 0.3% MZO could improve the growth performance and ATTD of DM; inclusion of 0.1% MOP could decrease feces E. coli shedding and also decrease the zinc level in feces in weanling pigs.
