Aflatoxin B

1. Both male and female Cynomolgus (Macaca irus) monkeys survived for 3 years without apparent ill health when fed on diets containing groundnut meal to provide up to 0·36 μg aflatoxin B1per g diet and thus supplying a mean daily consumption of up to 2 μg aflatoxin B1per kg body-weight. No histological changes attributable to aflatoxicosis were discovered in any of the organs from the monkeys receiving these quantities of aflatoxin.2. Few monkeys survived for more than a month or two when given a diet containing 1·8 μg aflatoxin B1per g, which provided about 50 μg aflatoxin B1per kg body-weight per day.3. No depression in growth rate nor effect on health was noted in those monkeys which survived on diets containing 1·8 μg aflatoxin B1, nor in any of the other monkeys.4. Histological changes were observed in the livers of all monkeys receiving the diet containing 1·8 μg aflatoxin B1per g for more than a month or two, but no abnormalities related to aflatoxicosis could be detected in any of the other organs, except for minor changes in the kidneys of two monkeys.5. No tumours were seen in any of the monkeys, even in those surviving for 3 years on diets providing 1·8 μg aflatoxin B1/g. Thus, no conclusions can be drawn from this work as to the carcinogenicity of aflatoxin in monkeys (still less in man), because the animals were young and little is known of the duration of exposure required to demonstrate carcinogenicity in this species.

Abstract. Title of the paper: Milk ingestion and growth performance of suckler calves (cross breeds Galloway x F1 Galloway x Holstein Friesian) from a cow-calf operation. Effects of sex and of life age of calf and of the age of dam On cross breeds (Galloway x F1 Galloway x Holstein Friesian; 12 calves from first pregnancy, 13 calves from second pregnancy; 10 male and 15 female) in a cow-calf operation measurements of body weight were done repeatedly during growth after separating the calves from the dams for 150 min and than again after the calves had contacted the dams for 60 min. Measurements took place always at the same daytime. Milk ingestion of calves was assessed by way of body weight difference method. Acute body weight difference varied markedly between calves and increased with age. The fraction of positive weight difference of all measurements was between 57,1 % and 91,8 % in calves from first pregnancy and between 54,8 % and 90,5 % in calves from second pregnancy the means of which were not significantly different. Mean acute positive body weight changes developed with life age and body growth with different degree in male and female calves. Greatest acute positive body weight changes of calves could be measured at 40 to 70 days of age (70 kg to 100 kg body weight). Growth rate of calves showed greater inter- and intraindividual variation within the first 10 days of life age. Differences in growth rate between male and female calves were more profound in calves from first then in those from second pregnancy.

Abstract. Title of the paper: Milk ingestion and growth performance of suckler calves born during winter stalling from German Red and White breed and from old type German Black and White breed in a cow-calf operation On 14 calves from German Red and White breed and on 17 calves from old type German Black and White breed in a cow-calf operation measurements of body weight were done repeatedly during growth after separating the calves from the dams for 150 min and than again after the calves had contacted the dams for 60 min. Measurements took place always at the same daytime. Milk ingestion of calves was assessed by way of body weight difference method. Acute body weight difference varied markedly between calves and increased with age. The fraction of positive weight difference of all measurements was between 60 % and 86,2 % (male 60 % and 86,2 %; female 67,6 % and 80,6 %) in DRB breed and between 69,1 % and 89,3 % (male 72,9 % and 89,3 %; female 69,1 % and 82,6 %) in DSB breed. Means of all measurements showed a significant difference of acute positive body weight change and of growth rate between breeds and sexes. Mean acute positive body weight changes developed with life age and body growth with different degree in male and female calves. Growth rate of calves showed greater inter- and intraindividual variation from 1 to 10 days of life age. Differences in growth rate between male and female calves were more profound in DRB breed than in DSB breed.

The research purpose is to investigate the characteristics of bandicoot’s (Echymipera kalubu) carcass in the Manokwari Regency, West Papua Province. Thirty-two (32) bandicoots, with the age of ± 4-month-old, were used for this study, the subjects consisted of 16 males and 16 females. The research method used was the exploration method. The results showed that the bodyweight of males and females bandicoot was 1709.38 ± 506.31 g and 976.63 ± 296.11 g (P<0.05). Carcass weight of males and females bandicoot was 1339 ± 449.53 g and 738.22 ± 233.50 g (P<0.05) respectively. Carcass percentage of males and females bandicoot was 77.15 ± 6.24 % and 75.10 ± 4.32 % (P>0.05). The weight cut forequarter of males and females bandicoot was 614.85±221.87 g and 311.67±101.83 g (P<0,05). The weight cut of the hindquarter of males and females bandicoot was 768.76±377.66 g and 397.89±142.18 g (P<0,05). Fore carcass percentages of males and females bandicoot were 45.48±2.20 % and 42.39±3.50 % (P<0,05). Hind carcass percentage of males and females bandicoot was 56.22±12.22 % and 53.63±6.82% (P>0,05). In conclusion, there are differences in body weight, carcass weight, fore carcass weight, rear carcass weight, and the percentage of fore carcass weight between male and female Echymipera kalubu. On the other hand, there is no difference in the percentage of carcass and rear carcass percentage between male and female Echymipera kalubu.

The present experiment was carried out on farmers’ goats in their sheds in Rayale village of Kavre district for 150 days. Eighteen khari goats (both male and female), 8-12 months old and having similar body weight were randomly divided into three groups comprising of six individuals in each group. Three types of rations were formulated for the experimental goats. Feed intake by experimental goats in terms of green and dry matter was significantly different (P&lt;0.05) between the treatment groups. Growth rate of the goats fed with top dressed maize stover (treatment 2) was higher than the treatment 3 (seasonal fodder adlib + 200 g concentrate mixture) and treatment 1 (1/2 maize stover silage + seasonal fodder adlib + 200 g concentrate mixture). The lowest average daily gain (ADG) was found in treatment 3 where goats were fed conventional fodder and grasses supplemented with concentrate (18.4 g) followed by treatment 1 (24.6 g). <i> Nepal Journal of Science and Technology </i> Vol. 7 2006

Effective Strategies

Inefficient feed management strategy in aquaculture will increase the fish production cost. One of the most effective strategies to solve this problem is through a better understanding of the compensatory growth of cultured fish. O. niloticus BEST tilapia strain (total length: 7.23 ± 0.11 cm mean ± SD; Body weight: 7.04 ± 0.08 g mean ± SD) were reared in aquariums at 26.3 ± 1.4oC for 10 weeks. During the experiment, the control group was fed twice a day. The other two groups were deprived of food for one and two weeks and then fed twice a day during refeeding period. At the end of the experiment, the fish deprived for one week had a body weight, biomass and specific growth rate that were not significantly different from the control group. The body weight, biomass and specific growth rate of fish deprived for two weeks were significantly lower than the other groups. This study revealed that concentrations of ash and lower concentrations of protein and lipid on the deprived groups were higher compared to those without feed deprivation. Mortality of fish was lower than 9% and not significantly different among the treatments. Fish aggressive behavior was the main reason for injuries and death. Given the results, BEST tilapia strain was only able to reach complete growth compensation not longer than one week deprivation period. The results of the present study could be applied as basic information for further research on feeding management of BEST tilapia strain.

Three groups each of 16 mature sheep were allowed to graze on sown pasture for 26 months. One group was given reservoir water, containing approximately 0.3 p.p.m. F, to drink, but the other two groups were offered similar water to which had been added sufficient sodium fluoride to give final concentrations of 10 or 20 p.p.m. F. During the winter months the treated groups drank only 0.5 1. or less of water per day and ingested virtually no fluoride. During the summer months the daily consumption of water by the groups which received 10 and 20 p.p.m. F rose to between 3 and 4 l., and the daily intake of fluoride, expressed as fluorine, to approximately 30 and 60 mg F respectively, equivalent to 0.4 and 0.8 mg F per kg body weight. The overall mean daily intakes of fluoride for the whole experiment by the two groups were 18 and 33 mg F or 0.24 and 0.44 mg F per kg body weight respectively. The ingestion of the amounts of fluoride supplied by drinking water containing as much as 20 p.p.m. F appeared to have no adverse effect on general health, body weight, or wool production of mature sheep over a period of 26 months. A brown deposit was present on the incisor teeth of all sheep throughout the experiment but was more pronounced during periods when the pasture was green; it did not appear to be related to fluoride intake, for it was as severe among the control sheep as among the treated ones. No mottling of the incisors or molars was observed, nor was there any evidence of excessive or uneven wear on these teeth. Ingestion of fluoride brought about increases up to threefold in the fluoride content of the bones and teeth.

1. In order to determine the relation of pituitary weight to body weight in the female rabbit, data were collected from 48 female rabbits. These data appear to fall on a straight line when the logarithm of the pituitary weight is plotted against the logarithm of cleaned body weight, and a straight line was fitted using the formula y = axk. The value of the constant k was found to be 0.61. 2. From the data from 31 male rabbits a straight line was obtained by the same formula. The value of the constant k was found to be 0.57 as compared with the value 0.55 obtained by Robb for male rabbits. 3. The growth rate of the pituitary does not show any marked difference after puberty in male and female rabbits as has been recorded for the rat (Hatai). 4. Ten female rabbits were killed at varying periods after copulation and the relation of pituitary weight to body weight examined. No change in the relative size of the pituitary was detectable by the methods used, and it is concluded that any change in weight of the pituitary following copulation, if it occurs, must be slight.

The technological, nutritional, and sensorial quality of breasts and thighs with drumsticks of turkey male and female breeders was characterized by comparison with breasts and thighs with drumsticks of growing male and female turkeys from the Grademaker line (hybrid turkeys, n = 20 birds per sex and per physiological stage). The breeder turkeys were slaughtered at 397 and 410 days of age and 10.42 and 32.67 kg of body weight for the females and males, respectively. The standard turkeys were slaughtered at 75 and 103 days of age and 5.89 and 13.48 kg of body weight for the females and males, respectively. The differences observed between males and females on one hand and between standard and breeder turkeys on the other hand were mainly induced by differences in slaughter ages and sexual dimorphism on body weight. The meat of female breeders had characteristics close to those of female and male standard turkeys, whereas the meat of male breeders was clearly distinguishable, particularly by displaying lower tenderness and water holding capacity.

AbstractAge and growth of the little Indian squid Loliolus hardwickei (Gray, 1849) were studied using samples collected in the coastal waters of Arabian Sea. Statolith increment counts demonstrated that L. hardwickei has a fast growth rate (dorsal mantle length: 0.31–0.73 mm day−1 in females and 0.27–0.56 mm day−1 in males) and a short lifespan of less than 6 months. Females are the larger sex and their daily growth rates were higher than in males. The oldest male and female were 110 and 130 days old; the youngest mature female and male were 62 and 52 days old respectively. The oviducal fecundity ranged from 104–480 eggs, mean = 360 eggs (14–23 eggs g−1 body weight).

Young Growth

Removal of pouch young of Setonix can lead to the resumption of development of quiescent blastocysts. Thirty-six pouch young obtained in this way have been used in this study. As the time in days from resumption of development to parturition is known, accurate ages may be calculated without actual birth or copulation being observed. These 36 animals have been repeatedly measured during their pouch life, and body weight, pes length, and tail length over the full term of pouch occupancy are given as regressions of these measures versus age. Larger-scale regressions are given for the first 80 days of pouch life. A tabulation based on the three regressions and giving average measures at stated ages is also given. During pouch life there is no difference in growth rate between male and female pouch young. Growth proportions of field-reared and compound-reared animals of comparable nutritional status are also similar. It is therefore considered that growth rates are equal, and that the age-estimation procedure established on compound-reared animals is applicable to field animals.
