AbstractLamyctes fulvicornis is spanandric and most probably thelytokous in Sweden. The variation during development in the following characters is described: body-tength, head-length, ratio head-length/body-length and head-length/head-width, number of coxal pores, ocelli, antennal articles and teeth on forcipular coxosternite, projections on tergites 9, 11 and 13, spinulation, accessory apical claws on the 15th pair of legs, genitalia and the pattern on the cephalic shield. Also correlation with size within each post-larval stadium is given. The boundary between juvenile and adult stadia and the number of post-larval stadia are discussed.

RAYSWE DUMARIS SIHOMBING, 2018: ''Reproductive Behavior and Morphology in Horses (Equus Caballus) Males in North Tapanuli District ''. Guided by HAMDAN and TRI HESTI WAHYUNI. This study aimed to see reproduction and morphological performance of the stallion in North Tapanuli Regency. This research was conducted in North Tapanuli regency, Silait-lait Village, Hutajulu Village and Siaro Village and Superior Breeding Cattle Hall and Animal Feed (BPTU-HPT) from June to August 2017. The analysis used in this research is quantitative data analysis which includes average, standard deviation and coefficient of diversity.The variable that distinguishes the horse is the part of reproduction which is divided into two, namely the exterior, which includes the diameter of the scrotum and the interior includes the quality of sperm that are tested miscroscopically and macroscopically. Macroscopic tests include volume measurement, viscosity, color, pH. Microscopic tests of motility, concentration, and abnormality. Morphology, including head length, head width, neck length, shoulder height, chest circumference, chest depth, body length, hip width, hip height.The results showed that stallion in North Tapanuli Regency had good sperm quality with gray white color, low concentration level, pH 6.67, motility 80%, concentration 13,76 x 10 ^ 7ml / ejakulat, and abnormality 16, 6% and morphological appearance have mean, standard deviation and high diversity coefficient with head length 62,30 cm, shoulder height 158,84 cm, chest circumference 174,26 cm, chest depth 78,20 cm, body length 169,86 cm , hip height 167.12 cm and hip width 40.01 cm. In conclusion of this study, the morphology and reproduction of horses in North Tapanuli Regency has good weight and posture and good sperm quality used as males in developing horse cattle.

Morphometric Characterization

Morphometric characterization of Katjang goat in Malaysia is important for conservation and for further genetic improvement. With this idea in view the present study was carried out to characterize the morphometry and to estimate the relationship among the important morphometric traits of indigenous Katjang goat. The study was conducted at the Faculty of Sustainable Agriculture (FSA), surrounding area of FSA Sandakan, Sabah and Batu Pahat, Johor in Malaysia. Characteristics of body weight (BW), body length (BL), heart girth (HG), wither height (WH), hip height (HH), fore leg length (FLL), hind leg length (HLL), head length (HeL), head width (HW), ear length(EL), ear breadth (EB), tail length (TL), scrotal length (SL) and scrotal circumference (SC) were gathered. In a single parameter as body weight of Katjang bucks at below 1 year, 1-2 year and > 2 years ages were recorded to be 7.41 ± 0.27, 14.20±0.20 and25.83 ± 0.99 kg, respectively. On the hand, body weight of Katjang does at 1-2 year and > 2 years ages were observed to be 12.41 ± 0.41 and 23.65±0.87 kg, respectively. In both sexes, head length, head width, tail length, ear length, ear breath, body weight, body length, hearth girth, wither height, leg length, hip height increases with the increment of the age of goat. On the other hand, all the parameters contemplated found comparatively higher in bucks than that of does.  Strong positive correlation was observed between scrotal length and scrotal circumference in Katjang bucks.Bang.

Acceptance Rates

This study was carried out to determine the effects of age and number of grafted larvae on acceptance rates, body weight, body length, head width and length, thorax width and length, and wing width and length of queen bees. One breeding and eleven starter hives were used for rearing queen bees. Totally, 495 one, two, and three-day-old larvae were grafted into starter hives comprising 30, 45, and 60 and 414 larvae were accepted; thus, generally, the acceptance rate was calculated as 83%. The best acceptance rate was calculated in three-day-old larvae group as 85.15%. There were found a statistically significant effect of the number of grafted larvae on body length and head width of queen. However, there were any effects on weight, head length, thorax width, thorax length, wing width, wing length, and acceptance rate of larvae. Age of grafted larvae did not have a statistically significant effect on head width, head length, wing width and acceptance rate of larvae. On the other hand, age of grafted larvae had a statistically significant effect on queen weight, body length, thorax width and length, and wing length of queen. If bee breeders wish to improve their stock, they should graft one-day-old larvae for rearing better queen bees.

Body measurements were recorded at birth, weaning, and one year of age on Shorthorn calves and on crossbred calves out of Shorthorn cows and Angus, Hereford, or Charolais bulls. A total of 254 calves was studied. There were significant breed-of-sire effects in all traits measured. In wither height, body length, and head length, Charolais-sired calves ranked first, followed by calves out of Hereford bulls. Angus-sired calves did not differ from the Shorthorn ones. In heart girth, body depth, and head width, the Shorthorn calves were consistently inferior to the others, while no uniform difference appeared among the three other breeds of sire. Crossbreeding did not modify the relative body measurements, as evidenced by the highly positive between-breed-sire correlations among the traits.
