Swainsonine is the primary toxin in locoweeds. It causes intention tremors, reproductive dysfunction, emaciation, and death. The objective of the present study was to evaluate the potential reproductive and developmental toxicities caused by swainsonine in mice. The treatment groups consisting of three generations of mice were given a range of concentrations of swainsonine by intraperitoneal injection (2.50 mg/kg body weight (BW), 1.20 mg/kg BW, 0.60 mg/kg BW, and 0 mg/kg BW). The 0 mg/kg BW group exhibited significantly fewer estrous cycles and an increased number of estrous ones compared to the 2.50 mg/kg BW, 1.20 mg/kg BW, and 0.60 mg/kg BW groups (P<0.05). All three generations of mice treated with swainsonine had significantly higher spleen, liver, and kidney indices and significantly lower body weights compared to the 0 mg/kg BW group (P<0.05). For the first and second generations of treatment group, the copulation indices and the numbers of live pups on postnatal days (PND) 0, 4, and 15 were significantly decreased compared to those of the 0 mg/kg BW group (P<0.05). The fertility and gestation indices of the treatment group of the first generation were significantly increased compared to the 2.50 mg/kg BW, 1.20 mg/kg BW, and 0.60 mg/kg BW groups of the second generation (P<0.05). Cumulatively, these results indicate that swainsonine may cause reproductive and developmental toxicities in mice in both parents and offspring.

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.

Goldthioglucose-obese mice cannot adjust their food intake to meet the increased energy requirements due to cold. At all ambient temperatures above 15°C the spontaneous running activity of these animals is less than that observed for nonobese controls. Activity of obese mice is maximal at 19°C and minimal at 15°C or lower. Body weights decrease during exposure to cold. In contrast to that of obese mice, running activity of nonobese controls is maximal at an ambient temperature of 25°C but nearly ceases at 15°C or lower. The food intake of these animals increases in the cold and remains elevated even at temperatures at which activity decreases. The body weight of nonobese controls is either maintained constant or increases during exposure to cold air.

Aim: To determine the effects of antimalaria and antheminthic drugs combination in the incidence of histopathological alteration and biochemical modulations in liver and kidney of albino rats. Place and Duration of Study: The study was undertaken at the Zoology Department University of Lagos Akoka Lagos Nigeria. Methodology: A total of twenty (25) Male adult albino rats of 13-15 weeks old were divided into 5 groups of 5 rats each and daily oral administration of human therapeutic doses of praziquantel (PZQ 50 mg/kg body weight) separate and in combination with ivermectin (IVM 0.4 mg/kg body weight), albendazole (ALB 15 mg/kg body weight) and Artemether-lumefanthrine (ACT 140 mg/kg body weight) was administered with the  group which serve as the control receiving 1ml distilled water. Toxic effects due to these treatments were investigated using histopathological, biochemical and mutagenic indices at day 8th and 15th of the study. Results: Biochemical assessment revealed significant reduction in AST, ALT, ALP and potassium in the treatment group compared to the control. Increase in the level calcium, Albumin and bicarbonate were also observed in treatment groups. Histopathological assessment of the liver showed a general incidence of focal inflammation along the portal tract area, but did not show any differential severity across treatment groups except for single PZQ treatment group which were characterized by fatty infiltration. A general occurrence of mesangial damage and glomerula injury was observed in kidney tissues. Renal lesions were more severe in single PZQ + IVM treatment groups while mild lesions characterized renal tissue from PZQ+ACT treatment groups. Mutagenic effects as indicated by the high incidence of sperm head abnormalities was recorded across combination treatments especially in PZQ+ IVR and PZQ+ ACT groups. Conclusion: Findings suggest that combination therapies are synergistic and could result in nephrotoxicity, antidiuretic effects, dehydration and mutagenicity at human therapeutic doses.

ABSTRACT Background Prebiotics selectively stimulate the growth of beneficial bacteria within the gastrointestinal tract, and have been investigated in human and animal studies for their capacity to improve intestinal health. Objective We investigated the prebiotics fructo-oligosaccharide (FOS), galacto-oligosaccharide (GOS), and mannan-oligosaccharide (MOS) for their potential to alleviate intestinal damage in rats. Methods Female Dark Agouti rats (6–8 wk old, 110–150 g) were allocated to 1 of the following treatment groups (n = 8/group): saline/water, saline/FOS, saline/GOS, saline/MOS, 5-fluorouracil (5FU)/water, 5FU/FOS, 5FU/GOS, and 5FU/MOS. Rats were pretreated with either 5% GOS, MOS, or FOS or vehicle (water) from day −12 to day 0. On day 0, rats received a single intraperitoneal injection of saline or 5FU. Metabolic data were recorded daily and all rats were killed on day 3. Histopathology was quantified in hematoxylin and eosin–stained sections. Intestinal sucrase and myeloperoxidase activity were quantified by biochemical assay. Fecal SCFAs—acetic, propionic, and butyric acid—were also measured. Statistical analysis was by repeated-measures, 2-factor ANOVA or Kruskal–Wallis and Mann–Whitney U test; P < 0.05 was considered statistically significant. Results Body weight was significantly decreased in all treatment groups after 5FU injection, with no change in body weight observed in any prebiotic treatment group. Total food intake was lower by ≥7% in the GOS treatment group pre-5FU than in all other groups (P < 0.05). Ileal villus height was 18% higher in GOS-treated rats pre-5FU than in respective water controls (P < 0.05). Jejunal and ileal villus height and crypt depth were significantly decreased in all treatment groups after 5FU injection, with no prebiotic effect observed. SCFAs were differentially increased in prebiotic treatment groups compared with water-only controls (P < 0.05). Conclusions FOS, GOS, and MOS have differential effects in modifying small intestinal pathology and SCFA profiles in rats with healthy and damaged small intestinal mucosa.

Background: Breast cancer chemotherapy with standard drugs such as doxorubicin will induce cardiotoxicity. Therefore, this study aims to evaluate the anticancer activity of C. odorata leaves extract in DMBA induced breast cancer on rats. Methods: Seven groups of Rattus novergicus were used: Four treatment groups of C. odorata extract (500, 1000, 2000, and 4000 mg/kg BW), normal control, breast cancer control, and doxorubicin treatment group. The number, volume, and weight of the nodule and the rats’ body weight were compared among groups. Data was analyzed using paired t-test or one-way ANOVA with post hoc analysis as appropriate. Results: Significant decline of the number, volume, and weight of cancer nodules was observed in the treatment group (p &lt; 0.001). The weight of the cancer nodule at week 16th was also significantly reduced in GCo2000 compared to Gdoxo (p &lt; 0.0001). A significant increase in body weight was also dose-dependent, especially at week 11th (p &lt; 0.05 in all comparisons) and week 16th (p &lt; 0.001 in all comparisons). Conclusion: This study suggested that the ethanol extract of C. odorata leaves has anticancer and antiproliferative activity.

Two hundred and fifty-five day-old Ross White strain broiler chicks were used to evaluate the Response and economic efficiency of broiler chickens fed graded levels of baker's yeast (saccharomyces cerevisiae) supplement during the harmattan season in the northern guinea savannah zone of Nigeria. There were five treatment groups for both starter and finisher phases. The experiment lasted for eight weeks. Each treatment group had three replicates with 17 birds per replicate and fifty-five birds per group in a completely randomized design (CRD). Treatments 1, 2, 3, 4 and 5 contained 0.0, 0.5, 1.0, 1.5 and 2.0% SC respectively. Results of the starter phase showed significant (P<0.05) differences in terms of final weight gain and feed conversion ratio (FCR). Treatment groups fed the control diet (0.0%), 0.5% and 1% SC had the best final body weight and body weight gain during the starter phase. The FCR was significantly (P<0.05) higher in the treatment group fed 0.5% SC during the starter phase. Mortality was higher (11.76%) in the control group compared to other treatment groups in the starter phase. During the finisher phase, treatment group fed 1.0% SC had significantly (P<0.05) higher final body weight, body weight gain and FCR. Apparent digestibility of crude protein, crude fibre, ether extract, ash, dry matter and nitrogen free extract were better in treatment groups containing SC. The economic efficiency results of this study indicated that the birds fed 1.0% SC were more profitable compared to those fed the control diet. The net profit of the treatment group fed 1.0% SC was N 650.01 compared to the control (N554.35). This study concluded that the optimum inclusion level of Baker's yeast (Saccharomyces cerevisiae) in the diet of broilers starter was 0.5% and 1.0% for finisher diet for improved performance in terms of weight gain and feed conversion ratio (FCR). It is suggested that broiler chicken farmers should be encouraged to include Baker's yeast in the diet of broiler chickens for improved weight productivity and better feed utilization.

Multiple-trait analyses have been shown to improve the detection of quantitative trait loci (QTLs) with multiple effects. Here we applied a multiple-trait approach on obesity- and growth-related traits that were surveyed in 275 F2 mice generated from an intercross between the high body weight selected line NMRI8 and DBA/2 as lean control. The parental lines differed 2·5-fold in body weight at the age of 6 weeks. Within the F2 population, the correlations between body weight and weights of abdominal fat weight, muscle, liver and kidney at the age of 6 weeks were about 0·8. A least squares multiple-trait QTL analysis was performed on these data to understand more precisely the cause of the genetic correlation between body weight, body composition traits and weights of inner organs. Regions on Chr 1, 2, 7 and 14 for body weights at different early ages and regions on Chr 1, 2, 4, 7, 14, 17 and 19 for organ weights at 6 weeks were found to have significant multiple effects at the genome-wide level.

This study aimed to evaluate the effect of post-hatch fasting time on the weights of body and digestive organs of chicks. Fertile eggs from 62-week-old broiler breeders (Cobb Fast lineage) were incubated and, after hatching, female chicks were randomly divided into six treatments, which corresponded to fasting periods (0, 6, 12, 24, 48, and 72 hours), with 40 chicks per treatment. At 01, 03, 06, and 10 days after hatching, measurements of body weight; residual yolk weight; relative weights of proventriculus + gizzard, intestine + pancreas and liver; and intestine total length were made. At 6 days of age, the chicks submitted to post-hatch fasting, for up to 12 hours, demonstrated greater development, with body weights higher than the other birds. Yet, when fed, no compensatory gain was observed and, at 10 days of age, the birds submitted to 48- and 72-h fasting remained with a lower body development. Intestine growth was also compromised by post-hatch fasting, being reduced in both weight and length. A post-hatching fasting of up to 24 hours did not interfere with the weights of body and digestive organs of 10-day-old female broiler chickens. However, 48- and 72-h post-hatch fastings affected adversely the weight and growth of digestive organs in the birds.

Abstract The efficacy of flumethrin 1% pour-on (1% w/v, Flumitas) was evaluated against Haematobia exigua on cattle farms in Namakkal district, Tamil Nadu from November 2019 to February 2020. In this study, five farms, which had fly menace, selected randomly were divided as treatment (F1, F2, F3 and F4) and control (Fc) groups. Flies collected from the farms were identified as Haematobia exigua and a mean pre-treatment intensity was 195.56 ± 14.07. In the treatment groups (F1,F2,F3 and F4) flumethrin 1% pour on was applied to the back of cattle at the rate of 1 ml/10 kg body weight and fly intensity was recorded for a period of 2 months. The fly intensity reduced to zero within 30 minutes of application and the same trend continued till 28 DPT in F2 and F3, while it was effective 35 DPT in F1 and F4. A highly significant difference in the mean H. exigua fly counts between control and treatment group (P < 0.0001) was observed.

Two synchronization protocols for fixed-timed AI (FTAI) in White-tail deer were evaluated over a 2-year period. InYear 1, White-tail does (n = 38), with a mean body weight of 55 kg and mean age of 2.4 years, were stratified by weight, age, and last fawning date randomly across 2 estrous cycle synchronization treatment groups. Does received either a CIDR-G device for 14 days (CIDR 14) and underwent AI 60 h post-CIDR removal, or received a CIDR-G device for 7 days (CIDR 7) with 1 mg of estradiol benzoate (i.m.) at CIDR insertion (Day 0), 25 mg of prostaglandin F2α (PGF2α; Dinoprost) on Day 6 and 1 mg of estradiol benzoate (i.m.) on Day 7 with AI occurring 52 h post-CIDR removal. In Year 2, White-tail does (n = 36), with a mean body weight of 60 kg and mean age of 3.9 years, were stratified as described for Year 1 and allotted to 2 treatments. Does received a CIDR-G device for 14 days and were inseminated 60 h post-CIDR removal (Treatment A) or were synchronized in the same way as does inTreatment A but also received 200 IU (i.m.) of eCG (Sigma, St. Louis, MO) at CIDR removal (Treatment B). All does received 1 mg of Domosedan (i.v.) before initiating the AI procedure. In both years, electroejaculated semen was collected from a single buck and frozen for AI. In both years, clean-up bucks were introduced into the pen with does for natural cover at no less than 14 days following AI. A gestation length of 195 � 7 days was used to determine whether the fawn(s) resulted from AI or from natural mating. In Year 1, FTAI pregnancy rates were not different between the CIDR 14 (56%) and CIDR 7 (24%) treatment groups. Likewise, pregnancy rates were not different between CIDR 14 FTAI (56%) and clean-up bucks (75%). However, the FTAI pregnancy rate was lower (P < 0.001) for the CIDR 7 treatment group (24%) compared with the clean-up bucks (100%). Treatments did not affect fecundity rates; however, those females pregnant from FTAI had lower (P < 0.001) fecundity rates compared with those females pregnant from natural cover (1.2 v. 1.9 fawns/doe). In Year 2, treatment did not affect FTAI pregnancy rates across treatments (33% for Treatment A and 55% Treatment B); however, fewer (P = 0.024) does in Treatment A were pregnant following FTAI (33%) compared with those pregnant from clean-up bucks (75%). There was no difference in FTAI fecundity rates across treatment groups (1.3 v. 1.7 for Treatments A and B, respectively) or between FTAI treatments and natural cover (1.3, 1.7, and 1.5 for Treatments A, B, and clean-up bucks, respectively). These results indicate that the use of a 14-day CIDR synchronization protocol with FTAI occurring 60 h after CIDR removal yields acceptable pregnancy rates of White-tail does following transcervical AI.
