ABSTRACT The growth of the long bones and the development of the epiphyseal cartilage were studied in 50 male and 33 female Muscovy ducks from the time of hatching up to the 18th week. An average body weight was measured of 1990 ± 18 g in the females and of 2838 ± 99 g in the males after 10 weeks. No further increase in the body weight was noted in the females. The males continued to grow up to the 18th week and reached a final weight of 4101 ± 62 g. In the femur, the tibiotarsus, and the tarsusmetatarsus a sex difference occurred in the 2nd week and became significant after 4 weeks. The greatest difference was observed in the tibiotarsus which reached a length of 125.4 ± 0.7 mm in the male and 103.2 ± 1.1 mm in the female after 10 weeks. In both sexes the greatest increase of bone length was noted within the first 4 weeks. The bone growth ceased and the epiphyseal cartilage disappeared with about 8 weeks in the female and with about 10 weeks in the male. The humerus, the ulna and the radius were somewhat larger in the female than in the male after 4 weeks. Thereafter a more rapid growth was seen in the male. The greatest sex difference was observed in the humerus which measured 136.0 ± 1.6 mm in the male and 113.8 ± 0.9 mm in the female after 10 weeks. In contrast to the leg bones the greatest increase in body length occurred between the 6th and the 8th week. The bone growth ceased after 10 weeks in the female, and after 12 weeks in the male. Growing males which were treated with 35 mg stilboestrol weighed 2034 ± 90 g after 10 weeks. The long bones only grew to 85–90 % of the normal length. Birds which were allowed to survive a further 8 weeks after the treatment, attained a body weight of 3494 ± 111 g without any further increase in the length of the leg bones and only a slight increase in the length of the wing bones. The dwarfing effect of stilboestrol was not caused by a precocious disappearance of the epiphyseal cartilage. An identical treatment with stilboestrol had in Pekin ducks no effect on body weight or on the long bones.

The study aimed at describing objectively the interdependence between body weight (BWT) and morphometric traits in Khaki Campbell and Pekin ducks using multivariate path analysis technique. Measurements were taken on one hundred and ninety seven (197) randomly selected 10-week old Khaki Campbell and Pekin ducks, respectively in Plateau State, Nigeria. The birds were reared on deep litter in a semi-intensive system where they were kept in a fenced area provided with water ponds and locked up in the poultry house during the night. The body parts measured were, body length (BDL); thigh length (THL); thigh circumference (THC); breast circumference (BTC); bill length (BLL); neck length (NKL); neck circumference (NKC); shank length (SHL); shank width (SHW); total leg length (TLL) and wing length (WL). General linear model was used to study genotype and sex effects. Pekin ducks had a superior advantage (p<0.05) over their Khaki Campbell counterparts in all the body parameters estimated. Sexual dimorphism (p<0.05) was in favour of male ducks.  Pairwise phenotypic correlations between BWT and morphometric traits were positive and significant (p<0.01), ranging from 0.38-0.95 and 0.35-0.92 for Khaki Campbell and Pekin ducks, respectively. Path analysis revealed that BDL was the variable of utmost importance directly influencing BWT in male Khaki Campbell and Pekin ducks (path coefficient=0.535 and 0.508, respectively; p<0.01) while BTC and SHL were the most responsible parameters affecting BWT in female Khaki Campbell and Pekin ducks [path coefficient=0.594 (P<0.01) and 1.197 (p<0.05), respectively]. The optimum regression models for the prediction of BWT in Khaki Campbell ducks included BDL, SHL, BTC and NKC (male)  and BDL, WNL and BTC (female); while in their Pekin counterparts, BDL, BLL and BTC (male) and BDL and SHL (female) were incorporated.DOI: http://dx.doi.org/10.3329/bjas.v44i1.23112            Bang.

Abstract Local chickens in developing countries, including Indonesia, have great potential to be developed into natural superior breeds to support food security and improve farmer welfare. Meanwhile, the major endemic subspecies found in the Bengkulu province are burgo and kampung chicken, as well as ketarras which are recently bred intensively. Therefore, this study aims to analyze the disparities in the morphometrics of three subspecies of local male chickens specifically on the body weight, length, chest girth and length, as well as wing span. Based on the results, the male burgo chicken morphometrical size was significantly smaller than ketarras, while the ketarras chicken was significantly smaller than kampung (P < 0.05). Furthermore, the average body weights for the burgo, ketarras and kampung chicken were 1.0, 1.2 and 1.9 kg cock-1, respectively, while the average of body length, chest and chest length, as well as wing span were 29.9, 40.0, 47.7 cm cock-1; 26.2, 30.1, 36.3 cm cock-1; 12.6, 17.8, 20.3 cm cock-1, and 34.4, 41.9, 55.9 cm cock-1, respectively. Therefore, it was concluded that the burgo and kampung chicken have the smallest and biggest morphometric sizes respectively.

The objective: to develop a regional gestational percentiles table of body weight for newborns in Kiev and Kyiv’s oblast. Materials and methods. Data of the body weight of newborns were collected from Kyiv City Perinatal Center from January 2016 by January 2017. The total number included 5244 live births in the period of gestation 40+0–40+6 weeks of gestation. The standard deviation of the body weight, expressed as the percentage of the average body weight of all newborns, as well as the percentil calculator developed by Hadlock et al, supported by the WHO (2008), was used to generate the percentages and curves of the body weight. Materials and methods. A newborn body weight percentile table was constructed, depending on the gestational age. Differences were observed between the current average body weight of newborns for Kyiv and current WHO links. Conclusion. We found a rise in the average body weight of newborns, which we associate with excessive, unbalanced diet and the prescribing of a complex of multivitamins and biologically active substances during pregnancy. This indicates the importance of using this table for differential diagnosis of normal fetal growth from intrauterine growth restriction and small for fetal gestational age within the region of Kyiv and oblast. Key words: delayed fetal growth, percentile table of the city of Kiev, average body weight of newborns, percentile schedule.

Native breeds of ducks have been the subject of many studies in the past, yet the relevant knowledge is still incomplete and needs to be further expanded. The objective of this study was to provide information about differences in growth performance, dressing percentage, carcass composition and digestive morphometry among three lines of Pekin ducks from conservation flocks raised in Poland. The study used 180 sexed Pekin ducks—30 males and 30 females of line P33 (ducks of Polish origin), 30 males and 30 females of line P8 (ducks of Danish origin), and 30 males and 30 females of line P9 (ducks of French origin). Throughout the study (49 d), ducks were confined indoors in six pens. Birds were fed complete commercial diets ad libitum and had unrestricted access to water. The compared lines of ducks differed significantly in body weight from 1 to 49 d of age except of ducks of both sexes at 14 d. At 49 d of age, significant differences were observed between the tested ducks in all the body measurements. Duck genotype had a significant effect on preslaughter body weight, carcass weight and breast muscle, neck and remainders contents, caeca length, liver weight and gizzard percentage. The results show that the tested ducks were significantly different and unique, mainly in terms of the body biometric characteristics.

The results of reproduction were tested in females of the African catfish (Clarias gariepinus Burchell 1822) after stimulation of ovulation with carp pituitary (4 mg/kg body weight) or with Lecirelin (15 &mu;g/kg) and metoclopramide (10 mg/kg). After administering the synthetic substance eggs were obtained from all females while in the group treated with pituitary homogenate 7 out of 8 hypophysed females spawned. The applied spawning agent did not significantly influence the weight of eggs expressed in grams, but in the case of females treated with carp pituitary homogenate a significantly higher weight of eggs expressed as the percentage of body weight of fish was recorded. The applied stimulators of ovulation did not affect any trait reflecting the quality of eggs. Females used as an experimental material belonged to two categories in respect of body weight: lighter females with average body weight of 2.63 &plusmn; 0.36 kg and heavier females with average body weight of 3.91 &plusmn; 0.48 kg. It was proved that the weight of eggs expressed either in grams or as a percentage of a female&rsquo;s weight was significantly related to the body weight of a female (P &le; 0.01 and P &le; 0.05, respectively), as well as the percentage of fertilised eggs and the percentage of living embryos after 28 hours of incubation (P &le; 0.05 and P &le; 0.05, respectively). The interaction between the stimulator of ovulation and the female body weight was significant only for traits reflecting the weight of obtained eggs (P &le; 0.05 and P &le; 0.01). &nbsp;

Benzo(a)pyrene (BaP) is one of several examples of polycyclic aromatic hydrocarbons that come from incomplete combustion of organic materials.BaP compound is used in research to induce fibrosarcoma.In general, patients with cancer will experience a reduction in body weight. This study aims to determine the body weight profile, the time it takes to cause fibrosarcoma, and the mortality rate of male Sprague Dawley rats after injection with BaP. In this study, 18 rats were used with two treatments.Rats in treatment 0 (P0) were not treated, while rats in treatment I (PI) were injected with BaP 0.3% in 0.1 mL oleum olivarumten times given gradually at two-day intervals via subcutaneous. There were six and 12 rats, respectively, P0 and PI. BaP solution is prepared by dissolving in oleum olivarum, mixing, and stirring until homogeneous. The rats were weighed at the beginning of the study and then carried out routinely once a weekfor 19 weeks of research. At the beginning of the study, the average body weight of rats at P0 and PI were 121.43 ± 7.04 g and 131.49 ± 16.31 g, respectively. The mean body weight of the rats at P0 and PI from the first week to the 19th were178.53 ± 29.97 g and 159.20 ± 14.24 g, respectively. The time taken to inducefibrosarcoma was 85.5 ± 17.6 days. The mortality rate in treatment P0 was 0% and PI treatment was 8.33%.From the results of this study, it can be concluded that giving BaP significantly reduces the body weight profile of rats and has a mortality rate of 8.33%.

Average Body Weight

The body weight of calves in the earliest period of their life (age from 0 to 7 days) is under the greatest influence of the farm and the season of birth. The farm manifests its influence most often through the conditions of nutrition and housing and the organization of the technological production process, while the influence of the birth season is manifested through microclimatic and nutritional conditions, as well. The most common deficiencies related to the nutrition of newborn calves are related to: inadequate colostrum supply in terms of quality, quantity and time of colostrum intake, which is closely related to the organization of the technological production process on the farm. Dietary deficiencies affect the body weight of calves at birth and at 8 days of age. In a study conducted over a year (4 seasons), the colostrum diet of newborn calves of the HF breed on two farms (A and B) with a tied housing system was analyzed. Calves were fed colostrum on both farms at intervals, usually up to 2 hours, less often up to 4 hours after birth. The colostrum consumed came from the mother, most often, and less often from the other cow, while on one of the farms it was also used frozen. However, the amount of colostrum consumed was deficient, it was 1-2 l on farm A, and 2.5 to 3 l on farm B. The occurence of a deficient diet or other deficiencies in the diet of calves was indicated by the average body weight, measured at birth and at the age of 8 days. On farm A, a lower average body weight of calves (37.95 and 39.68 kg) was recorded than on farm B (40.00 and 41.80 kg) by age categories, respectively. The average body weight of calves was statistically significantly (p <0.01) influenced by the farm and the season of birth, as well as their mutual interaction, but the effect of the farm was more pronounced.

Abstract In Papua, especially in the Arfak Mountains, one of wild animals that commonly used as a non-animal protein source is frogs. Although it has been consumed by local people for generations, there is no representative information on the characteristics of Arfak frog meat. This study aims to determine the body weight and weight of carcass of Arfak frogs (Rana arfaki) comsumed by the Moiley communtiies in the Arfak Mountains. In addition, this study also attempts to reveal the physical quality and processing techniques of consumed Arfak forg meat. We used descriptive method with observation techniques in the field. The results show that an average body weight of Arfak frogs consumed in Mbenti is 2.53 ± 0.81gr, with an average of carcass percentage 46.77% and non-carcass percentage 53.23%.  The physical quality of the meat is, fresh and looks intact, the color of flesh and muscles is white to yellowish white, has a distinctive aroma, and elastic texture as well as strong muscles. The pH value of fresh meat is an average of 7.03. Various meat processing techniques are practiced including fried, stir-fry, grilled and smoked, and pickling/smoked is more preffered bacuse it is easy and the meat can keep longer as a source of food for household animal protein.

An experiment was carried out with young male New Zealand White (NZW) rabbits to establish live body weight changes, body measurements, body composition and sexual maturity as a function of feeding intensity. Animals in Group 1 ('AL', n = 10) were fed ad libitum, while those in Group 2 ('RS', n = 10) received restricted feeding corresponding to 70% of the ad libitum level. The starting liveweights were practically the same (0.907 ± 0.146 and 0.911 ± 0.147 kg in Group AL and Group RS, respectively). The feeding trial lasted from 6 to 22 weeks of age. The average body weight was significantly higher in Group AL from 7 to 22 weeks of age. At 22 weeks of age the body weight of RS rabbits was 85.64% of the weight of AL animals (3.22 ± 0.52 kg and 3.76 ± 0.33 kg, respectively). Average body weights of RS males at 8, 9, 11, 19 and 21 weeks of age were similar to those of ad libitum fed (AL) animals at 7, 8, 10, 15 and 16 weeks of age, respectively. The growth of bucks fed restricted tended to be allometric. The most significant difference was found at 16 and 18 weeks of age, while the lowest difference occurred at 6, 12, 15 and 19 weeks of age. It can be stated that low-intensity feeding up to slaughtering weight causes backwardness in rear cannon length and this backwardness remains also after the 15th week, which is well over the optimal slaughtering age. Based on the present data, the 70% restricted feeding cannot be recommended either for the future breeding bucks or for broiler males reared for slaughter. To determine the major chemical components of the body, rabbits were euthanised. Original dry matter and crude fat content of the body significantly (P < 0.05) decreased under restricted feeding (41.42%; 32.48% and 16.73%; 7.35%) while the percentage of protein within the dry matter increased (49.6%; 65.0%) and fat decreased (40.17%; 22.1%) significantly. Libido unambiguously decreases as a consequence of feed deprivation. The most conspicuous difference was found in the level of blood testosterone. Although a few RS bucks produced semen but only much later than the rabbits fed ad libitum. On the other hand, there was no difference in the motility of spermatozoa and ejaculate volume in comparison with AL animals. There was no relationship between the body fat content and the reproductive status of bucks in the present trial.

An experiment was conducted to evaluate the performance of buffalo calves and cow calves supplementing Urea Molasses Block (UMB) with straw based diet. Three cow calves (average 1 year & 8 months age and 111 kg body weight) and three buffalo calves (average 1 year & 10 months age and 89 kg body weight) were grouped into A and B, respectively and fed for 60 days. It was found that, the DMI (kg/h/d) was 5.66±1.18 and 6.10±0.99, respectively in group A and B (p>0.05). The DMI in 1st and 2nd fortnight of the experiment in group A and B were 5.77±0.31 and 6.17±0.33; 4.96±0.43 and 5.77±0.39, respectively (p<0.01). But, the DMI in 3rd and 4th fortnight differs nonsignificantly (p>0.05). At the end of the experiment, the final body weight for group A and group B were 132.6±11.96 and 113±8.19 kg, respectively (p>0.05). The body weight gain per day for both groups were 0.36±0.05 and 0.40±0.05 kg, respectively (p>0.05). The average heart girth gain per day in group A and group B were 0.24±0.02 and 0.30±0.03 cm, respectively (p>0.05). The average wither height gain per day was 0.075±0.005 and 0.059±0.005 cm in group A and B, respectively (p<0.05). The average body length gain per day for group A and group B were 0.31±0.03 and 0.36±0.04 cm, respectively (p>0.05). The growth performance of buffalo calves is better than cow calves by feeding UMB with straw based diet.
