ABSTRACT Repetitive extragenic palindromic PCR fingerprinting of Escherichia coli is one microbial source tracking approach for identifying the host source origin of fecal pollution in aquatic systems. The construction of robust known-source libraries is expensive and requires an informed sampling strategy. In many types of farming systems, waste is stored for several months before being released into the environment. In this study we analyzed, by means of repetitive extragenic palindromic PCR using the enterobacterial repetitive intergenic consensus primers and comparative analysis using the Bionumerics software, collections of E. coli obtained from a dairy farm and from a swine farm, both of which stored their waste as a slurry in holding tanks. In all fecal samples, obtained from either barns or holding tanks, the diversity of the E. coli populations was underrepresented by collections of 500 isolates. In both the dairy and the swine farms, the diversity of the E. coli community was greater in the manure holding tank than in the barn, when they were sampled on the same date. In both farms, a comparison of stored manure samples collected several months apart suggested that the community composition changed substantially in terms of the detected number, absolute identity, and relative abundance of genotypes. Comparison of E. coli populations obtained from 10 different locations in either holding tank suggested that spatial variability in the E. coli community should be accounted for when sampling. Overall, the diversity in E. coli populations in manure slurry storage facilities is significant and likely is problematic with respect to library construction for microbial source tracking applications.

A comparative study on the growth performance of African catfish (Clarias gariepinus) fed shrimp based diet (SBD), chicken offal based diet (COBD) and coppens feed was carried-out for 22 weeks in concrete tanks measuring 3.5 x 1.7 x 1.5 m3. Triplicate groups of 40 juveniles with average length of 9.15 ± 0.17cm and weight of 20.00 ± 2.58g were stored in each tank. A total of 360 juveniles were used throughout the study. Fish were fed daily at 3% of their body weight through-out the duration of the experiment. The nutrient composition of the 3 nutrients differed significantly at p<0.05. Weight gain (WG) (g) was highest (17189.33 ± 506.61g) in fish fed diet A (Coppens feed), followed by 15045.33±202.42 g (diet B) (SBD) and least (14357.33 ± 108.25 g) (diet C) (COBD). The Growth rate (GR) was highest in fish fed with diet A (111.62 ± 3.29 g/day), followed by 97.69±1.31 g/day (diet B), and least (93.23±0.70 g/day) in diet C. Specific growth rate (SGR) was highest in juveniles fed diet A (2.02 ± 0.02 %/day), followed by 1.94±0.01 %/day for diet B, and least (1.91±0.01 %/day) for diet C. Mean growth rate (MGR) was highest in juveniles fed diet A (11.88 ± 0.29 mg/day), followed by 11.74±0.15 mg/day for diet B, and least (11.69±0.09 mg/day) in fish fed diet C. The WG, GR and SGR varied significantly between the juvenile fish group fed the 3 diets at p<0.05, while MGR did not vary significantly between fish group fed the 3 diets at p>0.05. Fish fed diet A had a higher feed consumption (FC) (41650.00 ± 315.34 g/kg), than that fed diet B (39034.24 ± 86.34 g/kg) and then diet C (38276.00 ± 342.97 g/kg). Juveniles fed Coppens feed did better, with a feed conversion ratio (FCR) of 2.42 ± 0.06, followed by 2.59±0.04 for diet B and 2.67 ± 0.03 for fish fed diet C. Feed conversion efficiency (FCE) was higher in fish fed diet A (41.26±0.94 %), followed by 38.54 ± 0.54 % (diet B) and least (37.52 ± 0.51 %) (diet C). The FC and FCR varied significantly between the fish fed the 3 diets at p<0.05, while FCE was not significantly different between the 3 treatment groups at p>0.05. The water parameters of the culture water varied significantly between each treatment groups (p<0.05), and were within the rage suitable for normal growth of fish. Though coppens feed yielded better growth performance and feed utilisation, the use of COBD and SBD is recommended for fish farmers in Nigeria. More researches should be carried out on using chicken offals and shrimps in fish feed formulation.

Weaning Piglets

At weaning, piglets must adapt to considerable changes in their environmental, immunological, and nutritional status. This period of adaptation is accompanied by a reduction in piglet growth rate that has been associated with the shift from sow’s milk to a solid dry diet. Consequently, feeding management strategies that result in increased feed intake may increase piglet growth rate postweaning. This study evaluated the effects of providing feed as a gruel and feeding on floor mats on piglet performance for three weeks after weaning

Abstract This study evaluated the effects of dietary net energy concentrations on feeding behavior and growth performance of growing-finishing pigs monitored using a feed intake recording equipment (FIRE). Two hundred and sixteen (48.8 ± 5.6 kg) gilts were blocked by bodyweight and assigned randomly to 1 of 3 dietary treatments, which included low (2,350 kcal/kg), medium (2,450 kcal/kg), and high (2,550 kcal/kg) dietary NE levels. Pigs were housed in 18 pens for 68 d in four phases with 12 pigs and one FIRE station per pen. Bodyweight, feed consumption, and the amount of time and visit at the station of individual pigs were monitored every day by using FIRE. Pigs fed low NE diet spent more time (min) at the station during the first two weeks and visited the station more times with fewer amounts of time (min) per visit after two weeks compared with pigs fed medium and high levels of NE diets (P &lt; 0.05). The speed (g/min) and amount (g/visit) of feed intake were lower (P &lt; 0.05) during phase 3 and the overall period in low NE diet compared with pigs fed medium NE diet. Pigs fed medium NE diet tended to have a greater (P = 0.066) average daily feed intake at phase 4 than pigs fed low NE diet. Increasing NE levels linearly improved (P &lt; 0.05) average daily gain, feed conversion ratio, and final BW during phase 3 and the overall period. However, the overall energy efficiency (Mcal NE/ kg gain) was linearly decreased with increasing NE levels. In conclusion, decreasing dietary NE to 2350 Mcal/kg resulted in more visits to feeders with slow ingestion speed compared with pigs fed diets with 2450 or 2550 Mcal/kg NE. Increasing dietary NE levels linearly improved daily gain and feed conversion ratio, but linearly decreased energy efficiency.

Gastric ulcers may be an underrecognized problem in the swine industry. An experiment was conducted to evaluate the effects of dietary melatonin supplementation and particle size on prevalence and severity of ulcers in growing pigs. Sixty-four Yorkshire barrows and gilts (29.5 ± 1.0 kg) received either a finely ground (763 ± 2.18 µm) or a coarsely ground (953 ± 2.29 µm) corn–wheat diet, either with or without added melatonin (5 mg kg−1). One half of the pigs underwent endoscopic examination to assess the severity of ulcers on days 4 and 25. Growth performance and feed consumption were monitored throughout the experiment. All pigs were slaughtered on day 28, and ulcers were assessed postmortem. Endoscopy at the beginning of the experiment found that 53% of the pigs already had some degree of ulceration. Pigs fed the fine diet had greater average daily gain and average daily feed intake than pigs fed the coarse diet (P < 0.05), but particle size did not significantly affect prevalence of stomach ulcers. Melatonin supplementation increased the apparent digestibility of crude protein (P < 0.04) and dry matter (P < 0.08) of the diets and decreased the prevalence of ulcers (P < 0.05) but did not significantly affect growth performance. Pigs that received melatonin had higher levels of melatonin (P < 0.01) in most gastrointestinal tissues, with highest concentrations found in the stomach (P < 0.001). Pigs that did not have ulcers had a higher concentration of melatonin in the plasma and stomach than pigs with ulcers (P < 0.05). Melatonin may be useful in decreasing ulcers. Initial ulcer condition may be a significant source of variation in growth experiments. Key words: Pigs, gastric ulcers, particle size, melatonin, gastrointestinal tract

An experiment was conducted to observe growth performance and survival of the larvae produced from the brood fish of Ompok pabda treated with 4 dietary levels of vitamin E for 90 days viz. 0 (served as control), 50, 100 and 150mg vitamin E/kg feed under 4 treatments i.e. treatment T1, T2, T3 and T4. After the feeding trials, the brood fish were induced to breed with equal dose of PG extract i.e. 12 and 18mg/kg body weight for male and female respectively and subsequently larvae were produced. The experiment was started with 5 days-old larvae having an average weight and length of 21.4 ± 8.6 mg and 13.8 ± 2.49 mm respectively in 16 bowls of 10l capacity divided into 4 treatments corresponding to the broods fish having 3 replications each with 100 larvae in each bowl i.e. 10 larvae per liter. After rearing for 28 days with live-food tubificid worms the highest growth rate in terms of weight (609.13 ± 15.20 mg) and length (86.70 ± 1.84 mm), gain in weight (587.78 ± 15.27 mg) and length (72.98 ± 1.81 mm), specific growth rate (30.36 ± 0.12%), health condition (16.63 ± 0.69 mg/mm) and survival (83.25 ± 2.87) were showed by the larvae produced from brood fish fed with 100 mg vitamin E/kg feed (treatment T3) while poorest was observed by the larvae produced from brood fish fed 150 mg vitamin E/kg feed. The results imply that inclusion of 100mg vitamin E/kg feed in the diet of O. pabda brood fish is best for enhancing growth and survival of larvae indicating that vitamin E has a positive impact. The results also suggest that inclusion of higher level of vitamin E in the diet exerts an antagonistic effect on the produced larvae.DOI: http://dx.doi.org/10.3329/pa.v20i1-2.16864 Progress.

The aim of the study was to investigate the effect of intestinal alkaline phosphatase (IAP) added to diets on growth performance, diarrhoea incidence (DI), blood metabolites, relative organ weight, and intestinal morphometry of weaned piglets challenged with enterotoxigenic Escherichia coli F4 (K88). A total of 64 crossbred entire male piglets (25-day-old and 7.16 ± 0.28 kg body weight) were allocated into four treatments: control diet (CD<sup>–</sup>), CD<sup>–</sup> + antimicrobial growth promoter (AGP), CD<sup>–</sup> + 15 mg IAP/kg of diet and CD<sup>–</sup> + 30 mg IAP/kg of diet, with eight replications. At 15 days, all piglets were orally challenged with 6 ml of a solution containing K88 (10<sup>6</sup> colony forming units/ml). Microencapsulated IAP in acid solution showed 14.43% solubility and pH values of 1.69, 1.72, 1.51, and 1.52 at the different times measured (0.5 h, 1.0 h, 17.0 h, and 24 h); differently, IAP in basic solution had 4.10% solubility and pH values increased (5.95, 6.10, 6.32 and 6.63) according to the different times, respectively. On days 25–35, piglets that received 30 mg IAP and CD<sup>–</sup> showed a better feed conversion ratio (P = 0.075) compared to those fed 15 mg IAP. Piglets that consumed 30 mg IAP or CD<sup>–</sup> had higher (P = 0.004) average daily gain on days 35–44. On days 35–44, the piglet average daily feed intake was lower (P = 0.033) with 15 mg IAP compared to AGP. In the entire period, piglets fed 15 mg IAP showed a reduction in average daily gain (P = 0.040) and average daily feed intake (P = 0.092). Piglets on 30 mg IAP showed an improvement (P ≤ 0.05) in DI in the pre-and post-challenge periods. The relative spleen weight of the piglet increased (P = 0.043) in response to 30 mg IAP. Overall, the addition of 30 mg IAP to diets improves the growth performance, attenuates DI, and promotes an increase in spleen relative weight to maintain the healthy state of piglets.

Rice whole stillage (RWS) is disposed to aerobic spoilage when stored for a prolonged period. The objectives of the present study were to evaluate the fermentation characteristics of ensiled RWS with wheat straw (WS) and wheat bran (WB) inoculated with Amylomyces rouxii, as well as to evaluate their impact on the metabolic profiles and the growth performance in Japanese black steers. Ensiled blends containing RWS, WS and WB were prepared either with A. rouxii inoculation (AS) or without (US). Fifteen silo bags were made for each blend; each bag had a width × height of 110 × 110 cm. The silos were analysed on Days 0, 7, 14, 28, 42 and 60 after ensiling. Notably, crude protein concentrations were found to be higher in the US treatment than in the AS treatment. In contrast, ash and acetic acid concentrations were elevated in the AS treatment compared with the US treatment. Lactic acid (LA) concentrations did not differ between the two treatments. Furthermore, the feeding efficacies of the prepared silages were evaluated as a feeding material for Japanese black steers. Control diets were composed of total mixed ration (TMR) and timothy hay, and the test diets were composed of TMR supplemented with either 1 kg/head.day US silage blend (USTMR) or 1 kg/head.day AS silage blend (ASTMR). Steers fed on the ASTMR diet exhibited a decrease in blood LA concentrations compared with the other groups. Moreover, growth performance revealed that daily gain and final bodyweight values were similar among treatments. Collectively, RWS can be effectively ensiled with or without A. rouxii and used as a feedstuff for maintaining an adequate growth rate of steers.
