One female and 19 male Weddell seals, Leptonychotes weddellii, were injected with the emetic apomorphine hydrochloride. Fourteen of these were immobilised with combinations of ketamine hydrochloride and diazepam before the emetic was injected. One seal was administered the emetic tincture of ipecac while immobilised. The mean induction dose of ketamine hydrochloride was 7.99 � 1.99 mg kg-1 (mean�SD) and that of diazepam was 0.05 � 0.01 mg kg-1. The mean induction time was 23.07 � 17.63 min and the mean duration of immobilisation was 127.00 � 20.72 min. Six of the 22 seals apomorphine hydrochloride vomited and the seal given tincture of ipecac did not vomit. The mean dose of apomorphine hydrochloride that produced vomiting in immobilised animals was 0.18 � 0.10 mg kg-1 and the mean dose of apomorphine hydrochloride that produced vomiting in non-immobilised animals was 0.22 � 0.15 mg kg-1. Three seals died after drug administration during the study. Post-mortem examinations were conducted on these animals and nothing abnormal was found. Seals were weighed on 15 occasions (weight range, 137-402 kg) and the relationship between standard length (L, in centimetres) and body weight (W, in kilograms) was found to be: W=3.66L- 489.30. Food comprising five species of fish, two cephalopods and one gastropod were identified. Nematodes and gastroliths were present in most vomit samples. Centrally acting emetics and dissociative anaesthesia were both found to have limitations for use in Weddell seals.

A total of 1183 Botia Dario (Hamilton) samples were collected from Rajshahi (Shaheb Bazar, Binodpur Bazar, Talaimari Bazar, Kazla Bazar and Godagari) during the period from January, 2002 to August, 2003 to study the fecundity, sex-ratio, relationship between fecundity and total length, standard length, body weight, ovary length as well as ovary weight. The mean fecundity was calculated as 31833.50±10313.42 with a range of 5245 to 53754 in fishes ranging in total length from 96 mm to 135 mm (mean 115.50±12.11 mm) and in body weight from 14.51 g to 43.29 g (mean 29.71±6.91 g). The relationship between the fecundity (F) and total length (TL), standard length (SL), body weight (BW), ovary length (OL) and ovary weight (OW) were found to be linear with the ‘r’ values 0.94, 0.94, 0.95, 0.92 and 0.98, respectively. The ovum diameter ranged from 0.3 to 0.72 mm and the mean diameter was calculated as 0.518±0.06 mm. The male to female ratio was 1:0.61. Key words: Botia dario, fecundity, sex-ratio. Univ. j. zool.

The relationship between thickness of fat measured at the shoulder, last rib, and loin of live pigs and market weight (86.2 to 95.2 kg) was studied in 1596 pigs from the Lacombe and Yorkshire breeds and their reciprocal crosses. No significant breed or sex differences were found in the proportion of fat at the three sites. Breed and sex differences were evident in the average depth of fat. The regression coefficients for the mean of three fat measurements on market weight were.016 ±.003,.019 ±.007, and.017 ±.004 for Lacombe males, barrows, and females respectively;.039 ±.002,.036 ±.005, and.041 ±.001 for Yorkshire males, barrows and females respectively;.027 ±.005 and.029 ±.004 for barrows and females from the Lacombe male × Yorkshire female mating; and.023 ±.007 and.021 ±.009 for barrows and females from the Yorkshire male × Lacombe female mating. Comparisons between animals measured at a relatively constant weight should be made after the fat measurement is adjusted for variations in body weight. The results of this study indicate that separate corrections should be applied for each breed. Separate corrections for sexes within breeds do not appear warranted.

The aim of the present study was to evaluate the relationship between BMI and tooth decay in a population of Iranian children. In this cross-sectional descriptive/analytical study, 1482 children were selected from kindergartens and preschool centers in Kerman, Iran. The children underwent examination of deciduous teeth (using the dmft index) after determination of height and weight for calculation of BMI. The relationship between BMI (after adjustment for age) and dmft was determined using Poisson’s regression model. The mean of dmft in children with normal BMI was 1.5-fold that in subjects with extra body weight. Age had a significant effect on dmft. In addition, dmft was higher in boys compared to girls. The results of the present study showed that caries rate in the deciduous teeth of 3–6-year-old children decreases with an increase in body weight.

Despite numerous published studies, the relationship between the amount of secreted cocaine and amphetamine regulated transcript and the daily body weight gain has still not been well explained. The aim of this study was to determine the incidence of cocaine and amphetamine regulated transcript in the outlet wall of the abomasum of bulls with different daily weight gains. The study was performed on 15 bulls, breed crosses of local black and white milk cattle and Limousin bulls. The animals were slaughtered at the mean age of 543–549 days and body weight of 441.0–491.4 kg. Fragments of the outlet wall of the abomasum were sampled for analyses during routine slaughter. Immunohistochemical assays showed that slowly growing bulls (803 g/day) had significantly (P ≤ 0.05) fewer positive structures of cocaine and amphetamine regulated transcript (by 1.65 × on average) compared to bulls with large daily weight gains (905 g/day). This tendency was also observed in the case of cocaine and amphetamine regulated transcript distribution in particular layers of the abomasum wall. The most numerous positive structures of cocaine and amphetamine regulated transcript were found in the nerve fibres of the muscularis and in the muscle plexus, whereas they were evidently less numerous in the submucous plexus. Our results suggest that the number of cocaine and amphetamine regulated transcript immunopositive structures is associated with the growth intensity of the animals, and frequent occurrence of this neuropeptide in the nerve fibres and the muscular plexus proves its role in the control of stomach emptying.

ABSTRACTVoluntary food intake and body weight were examined over 4-week intervals between 14 and 70 weeks of age in 306 females from 25 British breeds of cattle. At each age, the relationship of the natural logarithm of voluntary food intake to that of body weight was examined by linear regression both within and between breeds.Of the total variation in voluntary food intake, the proportion accounted for by body weight was extremely high between breeds (phenotypically, 0·80 or more; genetically 0·88 or more, at most ages) but phenotypically low within breeds (0·33 or less). The mean voluntary intake of a breed at any age could be predicted from its mean body weight at the same age with a coefficient of variation (CV) among breeds that declined with age from 0·08 to 0·04. Within breeds, the corresponding CV for individual intake was between 0·12 and 0·15 beyond 9 months of age, and even higher at early ages.Within breeds, the regression coefficient of log intake on log body weight was close to the value of 0·7 at all ages. Between breeds, it was over 0·8 at early ages, declining to about 0·7 beyond 1 year of age. Thus, genetically larger breeds voluntarily consumed relatively more food at early ages compared with later ages. Breed size should therefore be taken into account when recommending food intake requirements. Breed deviations for high and low appetite are discussed.

Fifteen yearling Weddell seals (Leptonychotes weddellii) were captured, measured, weighed, bled, equipped with time–depth recorders, and released to determine if diving behavior was related to physical condition. Upon recovery of the time–depth recorders, dives were classified into four types based on shape, using cluster analysis. Based on maximum depth, two groups were further subdivided, for a total of seven types. The mean and maximal dive depth, duration, and frequency were determined for each yearling for all dive types combined and for each type separately. Stepwise regression and ANOVA techniques were used to test the relationship between diving behavior and physiological and morphometric measurements. In general, half of the variation in the pooled diving behavior could be explained by body-size differences. Larger yearlings made longer and shallower dives than smaller yearlings. Dive patterns suggested that large yearlings foraged primarily on small shallow-water prey items, while small yearlings concentrated on energy-dense deep-water prey. However, the interpretation of diving behavior, foraging locations, and diet that resulted from separating individuals and dive types was very different from that based on average diving behavior. This argues against ignoring variation among individuals and using only average diving behavior when describing marine mammal dive patterns.

An experiment to determine the relationship between egg weight, hatch weight and subsequent body weight of the Japanese quail was conducted. A total of 607 eggs collected over 6 days from an existing flock at the Animal Pavilion of the University of Ilorin were used for the experiment. Eggs were individually numbered, weighed and grouped into small (S) medium (M) and large (L) sized eggs based on the mean and standard deviation of the eggs. Mean egg weight were correlated and regressed with mean hatch weight and subsequent weight. Average egg weights were 10.23± 0.84g, 8.49± 0.72g and 6.94± 0.93g for the large, medium and small group respectively. The result showed relationship between egg weight and hatch weight were positive and highly significant (P < 0.01) with values of 0.973, 0.977 and 0.967 for small, medium and large groups, respectively. Relationship between hatch weights and weekly body weights were also positive and significant (P<0.01) for the medium and large groups only but decreased with age. Linear regression equation showed a significant coefficient of determination for weekly body weight using the values for small, medium and large egg weight values. The results of the study showed that egg weight can be reliably used for estimating body weight in Japanese quail and may be used as criteria for early selection of Japanese quail for body weight.

The exotic barb Puntius gonionotus was introduced into Bangladesh in 1987. Its faster growth rate, nice taste and compatibility with our culturable species have made it very popular food fish in Bangladesh. With a view to providing some basic information towards development of sustainable seed production of the species, a study was undertaken to determine the fecundity and ovary characteristics of the fish. The mean fecundity of 55 gravid females (of 11 length group) of Puntius gonionotus was obtained as 14321 with a range of 2254.67 to 6964.73 from fishes having a mean total length and mean body weight of 200.13±20.58 mm and 196±34.379 g respectively. The relationship between the fecundity (F) and total length (TL), total body weight (TW), ovary length (OL) and ovary weight (OW) were established. Regression analysis was made and the co-efficient of correlation (r) was calculated for each of the following F-TL, F-TW, F-OL and F-OW and the values of r were obtained to be 0.84, 0.84, 0.95 and 0.96 respectively. In all the cases linear relationships obtained were highly significant. Key words: Fecundity, Puntius gonionotus, ovarian characteristics. J. bio-sci. 14: 99-102, 2006

AbstractData on prevalence and current distribution of the cestode Nippotaenia mogurndae Yamaguti and Miyata, 1940 (Nippotaeniidea) in Slovakia, are provided. A total of 163 fish from 8 localities of different types in the Tisa River basin were infected with N. mogurndae. The mean intensity of infection was 1.8 with a maximum of 5 tapeworms. The expansion of the distribution of the cestode corresponds well with the spreading of its host, the invasive fish Amur sleeper Perccottus glenii Dybowski, 1877. The Spearmann correlation coefficient was used to test the relationship between the intensity of infection and standard length of the fish (r = 0.36; n = 163; P < 0.05), condition coefficient of the fish (r = 0.22; n = 115; P < 0.05) and season (r = −0.37; n = 355; P < 0.05). A significant correlation was confirmed for each pair of variables. There is a statistically significant difference between the prevalence of the cestode in two functional size groups (t = 3.28; n = 163; P < 0.05). The prevalence of the cestode increased with the standard length of fish. The potential risk of further expansion of N. mogurndae to other countries is discussed.

The present study was conducted the status of sea bass from Kokko and Kyuntone of The Gulf of Motttama Wetland (GoMW) area in Thanatpin Township in Bago Region Myanmar from September 2019 to August 2020. Fifty specimens were monthly collected, measured and weighed. Invoices of sea bass were collected for the depot and fish sellers by monthly. In Kokko, mean value of standard length and body weight were highest in March (32.70±1.58, 660.7±112.23). The mean value of standard length was peak in January (31.39±7.16) but peak of body weight was in March (963.24±280.86) in Kyuntone villages. The lowest mean value of standard length and body weight were found in June at both study areas. According to the invoice data revealed that monthly catch weight of sea bass is most abundance in October (829.92) kg in Kokko, (339.12) kg in Kyuntone. Based on price of relations to size group, small size C &amp;lt; 300g (41%) was mostly abundance in Kokko and in Kyuntone small size C &amp;lt; 300g (35%) was second abundance. Specimens were not landed in April and May. In June, young specimens were very rarely seen in both study sites. The important roles of wetland fishes, the economic valuation of GOMW in Myanmar and samples of fishing gear and value chain of sea bass in Myanmar was expressed in this study.
