Black Bengal Goat

This piece of work was conducted to investigate the genetic improvement of body weight (BW) in Black Bengal goat (BBG) in-situ through a community based breeding program under a low input production system. Data on a total of 466 individuals from three villages; Gangatia, Borochala and Pachpai at Bhaluka upazila in Mymensingh district from 2009 to 2015 with three progressive generations were taken for this work. Two breeding strategies (BS); mating among selected superior bucks and does (denoted as BS1) and mating existing does with selected superior bucks (denoted as BS2) were followed for mating plan of the community breeding program. A control or test group with mating among existing bucks and does (denoted as BS3) were also observed to compare with treatment groups. Phenotypic performance and genetic parameters for BW traits were studied. Data were analyzed by SPSS 17.0 and VCE 4.2.5. The average BW at birth, 3-month, 6-month, sexual maturity, 9-month, and 12-month were 1.42±0.03, 5.14±0.07, 8.48±0.17, 9.88±0.16, 11.75±0.16 and 15.19±0.16 kg, respectively, having significant effect for sex (p<0.05-p<0.001), generation (p<0.001) and BS (p<0.001). The heritability estimates for BW traits were medium ranging from 0.45 to 0.57. The genetic correlation (rg) and phenotypic correlation (rp) for BW traits were positive with low to high strengths (0.02 to 0.99 for rg and 0.17** to 0.99** for rp). The average realized responses due to selection in three progressive generations for BW traits varied from 0.123 to 0.480 kg per generation. It may be concluded that community based breeding program with selected superior bucks and does is very rationale under low input production system, as it improved BW in progressive generations. However, estimates of heritability and rg indicated further scope of improvement by continuous culling of inferior does and bucks in breeding program.

Black Bengal Goat

The present study was undertaken to evaluate the availability of breeding bucks as well as growth and reproductive performances of Black Bengal goat under community based breeding program. A total of 30 goat rearers in three areas of Sakhipur upazilla were selected based on the survey result. Selected goat rearers were trained on scientific rearing, management and community-based breeding of Black Bengal goat and also build up community link with them. Three Black Bengal breeding bucks have been distributed among three potential farmers in three villages under Sakhipur upazilla. The management and performance of Black Bengal goats were monitored closely and analyze the impact of community based breeding program. The analysis of the growth performance showed that male kids attained significantly (p<0.05) higher birth weight (1.28±0.04 kg) than that of female kids (1.06±0.02 kg). The body weights of male at 3, 6, 9 and 12-month were 5.41±0.28, 9.18±0.32, 12.87±0.35 and 16.91±0.46 kg whereas female reached significantly (p<0.05) lower body weight as 4.97±0.16, 8.02±0.21, 10.91±0.23 and 14.21±0.34 kg at the same ages, respectively. Average daily body weight gain up to 12 months of age was also significantly (p<0.05) higher in males (43.42±1.17 g/day) than females (36.53±2.49 g/day). On the other hand, season had a significant effect (p<0.05) on the body weights of Black Bengal goat at 0 (birth), 3, 6, 9, 12-month of age. In case of reproductive performances, it was revealed that age at sexual maturity was 199.32±2.41 days; age at first kidding 393.23±1.38 days; service per conception 1.17±0.04, and litter size was 1.76±0.08 in community based breeding program. Beside these, post-partum heat period of Black Bengal goat was found 47.50±0.87 days. Comparing with the findings of previous research works, these results suggested that community based breeding program has not only reduced the scarcity of good quality breeding bucks but also improved the growth and reproductive performances of Black Bengal goats.

The Impact

The impact of lead toxicity was assessed in this study by analyzing the effects of the extracts on some electrolytes, urea and creatinine concentration. Thirty-five male wistar rats (150+50g) were distributed into five groups with seven rats in each group. Extraction and all biochemical analysis were carried out using standard laboratory techniques. Group one served as control, group two as test and were exposed to lead acetate only. Groups three, four and five were treatment groups, administered carrot and garden egg, carrot and tomato, garden egg, carrot and tomato respectively. All groups received feed and water ad libitum. Lead Acetate solution was administered orally at 50mg/kg body weight while 200mg/kg body weight received mixed juicy extract. On day 15, food was withdrawn, fasted overnight with free access to water. They were euthanized under chloroform vapor and sacrificed. Whole blood was collected via cardiac puncture for biochemical analysis. There was significant (P<0.05) decrease in potassium and chloride ion in group 2 (test group), compared to the control and treatment groups. Concentration of urea and creatinine in the test group was significantly higher compared with the other groups. Concentration of creatinine in group 3 and 5 significantly increased compared to control group. Effect of lead acetate was significantly reversed in group 5 compared to group 2. The results of the study indicate the potency of plants extracts against toxicity caused by the lead acetate. Flavonoids, saponins, tannins and alkaloids were present in the extracts.

Unconventional Feed

Background: Commercial broiler is a rapidly growing sector in Bangladesh. The broilers are supplied with the balanced ration prepared from a number of ingredients which are not available uniformly throughout the years. On the other hands, manufactured feeds are costly and inconvenient for the rural farmers. This study is undertaken to use unconventional feed ingredients aiming to decrease the broiler production cost. Method: A total of ninety-nine day- old broiler chicks (Hubbard) of either sex were used in this study in 3 treatment groups to assess processed unconventional feed item (shoti, blood meal, poultry dropping and molasses) on growth and profitability upon rearing for 60 days. Broilers were reared in dip litter system and were fed ad libitum on conventional and unconventional diet dividing into 3 treatment diets namely, treatment diet 1 (T1: Conventional as control), treatment diet 2 (T2: unconventional with blood meal and shoti), and treatment diet 3 (T3: unconventional with blood meal, shoti, poultry droppings and molasses) throughout the trial period. Treatment group 1 (T1) was used as control. Results: Broilers fed on control diet (conventional feed) achieved higher (P<0.01) body weight, while the broilers offered diets with the highest amount of unconventional feed had the lowest body weight. Increased (P<0.01) feed intake was observed during 21days and 49 days of age when broilers fed diets with the supplementation, but no significant differences were found among the groups in terms of feed consumption during 33 day of age. FCR differed significantly (P<.01) throughout the trial period with the broilers fed diets without supplementation of unconventional feed item had the superior FCR than the others. Mortality rate was 6.06%,9.09%, and 9.09% in treatment group I, treatment group II, and treatment group III respectively while live weights, feed conversion and feed consumption was unaffected by all the dietary groups with/without incorporation of unconventional feed item up to day 60 days of age. Statistically significant (P<0.01) decreased live weight was observed among the treatment groups in 60-day-old birds. Productivity and cost-benefit analysis were performed. Conclusion: Use of unconventional feed ingredients in broiler production greatly reduces the feed cost with little hampering the growth rate and hence, it is profitable for the farmers.

Gut Barrier Function

Abstract Background Gut is a crucial organ for the host’s defense system due to its filtering action of the intestinal membrane from hazardous foreign substances. One strategy to strengthen the gut epithelial barrier function is to upregulate beneficial microflora populations and their metabolites. Sophorolipid (SPL), which is a glycolipid bio-surfactant, could increase beneficial microflora and decrease pathogenic bacteria in the gastrointestinal tract. Therefore, herein, we conducted an experiment with broiler chickens to investigate the fortifying effects of SPL on the host’s gut defense system by modulating the microbiota population. Methods A total of 540 1-day-old chicks (Ross 308) were used, and they were immediately allotted into three treatment groups (6 replications with 30 chicks/pen) according to their initial body weight. The dietary treatments consisted of CON (basal diet), BAM (10 mg/kg bambermycin), and SPL (10 mg/kg SPL). During the experiment, birds freely accessed feed and water, and body weight and feed intake were measured at the end of each phase. On d 35, birds (one bird/pen) were sacrificed to collect jejunum and cecum samples. Results Dietary SPL and BAM supplementation significantly accelerated birds’ growth and also significantly improved feed efficiency compared to CON. Intestinal microbial community was significantly separated by dietary SPL supplementation from that of CON, and dietary SPL supplementation significantly increased Lactobacillus spp. and Akkermansia muciniphila. Moreover, birds fed with dietary SPL also showed the highest concentration of cecal butyrate among all treatment groups. Gut morphological analysis showed that dietary SPL significantly increased villus height, ratio of villus height to crypt depth, goblet cell numbers, and the gene expression levels of claudin-1 and mucin 2. Additionally, dietary SPL significantly decreased the mRNA expression level of pro-inflammatory cytokine, interleukin-6, and increased that of anti-inflammatory cytokine, interleukin-10, compared to other treatments. Conclusions Dietary SPL increases the beneficial bacterial population and butyrate concentration, which leads to a strengthened gut barrier function. In addition, the intestinal inflammation was also downregulated by dietary SPL supplementation.

The positive effects of nucleotide (NU) supplementation in milk replacer have been elucidated in infants and in dairy calves; however, NU addition to whole milk has not been evaluated previously. This study aimed to assess NU supplementation in the whole milk on calf growth and health. Thirty Holstein calves (body weight: 39.1 ± 1.0 kg; 3 d after birth) were randomly assigned to the following treatments: whole milk without any supplementation (NU0), whole milk + 0.5 g/d added a NU-containing supplement to whole milk (NUCS0.5), and whole milk + 1 g/d added a NU-containing supplement to whole milk (NUCS1). Calves were weaned at d 55 and stayed on study until d 75. Calves had free access to feed and water throughout the study. Dry matter intakes (DMI) were similar among treatments (p > 0.05) during the pre-weaning period; however, increasing NU resulted in a linear (p < 0.05) increase in DMI during the post weaning period (2158, 2432, and 2518 g/d for NU0, NUCS0.5, and NUCS1, respectively). Treatments did not affect body weight (BW) at the first and second month of study, but final BW linearly increased as NU was added (87.1, 90.6, and 95.4 kg for NU0, NUCS0.5, and NUCS1, respectively). Neither pre-weaning average daily gain nor post-weaning average daily gain was affected by treatments; accordingly, feed efficiency was similar among treatment groups. Days with loose fecal score were linearly decreased as NU was added to whole milk during the first month of life, while the fecal score did not differ among treatments until the end of the study. No difference was observed in the skeletal growth of calves in the current study. Therefore, it can be concluded that NU supplementation in the whole milk has some beneficial effects on calf performance in terms of final BW, post-weaning DMI, and less days with loose feces.

Abstract Background Ulcerative colitis (UC) is a chronic and recurrent disease without satisfactory treatment strategies. Dental pulp stem cell (DPSC) transplantation has been proposed as a potential therapy for UC. This study aimed to investigate the therapeutic effects of the rat hepatocyte growth factor (HGF) gene transduced into DPSCs for UC. Methods The therapeutic effects of HGF-DPSCs transplanted intravenously into a rat model of UC induced by 5% dextran sulphate sodium (DSS) were compared with the other treatment groups (LV-HGF group, DPSCs group and GFP-DPSCs group). Immunofluorescence and immunohistochemistry were used to observe the localization and proliferation of HGF-DPSCs at the site of colon injury. The expression levels of inflammatory factors were detected by real-time quantitative PCR (RT-PCR) and western blotting. The oxidative stress markers were detected by ELISA. DAI scores and body weight changes were used to macroscopically evaluate the treatment of rats in each group. Results Immunofluorescence and immunohistochemistry assays showed that HGF-DPSCs homed to colon injury sites and colocalized with intestinal stem cell (ISC) markers (Bmi1, Musashi1 and Sox9) and significantly promoted protein expression (Bmi1, Musashi1, Sox9 and PCNA). Anti-inflammatory cytokine (TGF-β and IL-10) expression was the highest in the HGF-DPSCs group compared with the other treatment groups, while the expression of pro-inflammatory cytokines (TNF-α and INF-γ) was the lowest. Additionally, the oxidative stress response results showed that malondialdehyde (MDA) and myeloperoxidase (MPO) expression decreased while superoxide dismutase (SOD) expression increased, especially in the HGF-DPSCs group. The DAI scores showed a downward trend with time in the five treatment groups, whereas body weight increased, and the changes were most prominent in the HGF-DPSCs group. Conclusions The study indicated that HGF-DPSCs can alleviate injuries to the intestinal mucosa by transdifferentiating into ISC-like cells, promoting ISC-like cell proliferation, suppressing inflammatory responses and reducing oxidative stress damage, which provides new ideas for the clinical treatment of UC.
