Abstract. Yendraliza, Rodiallah M, Zumarni, Elfawati, Hidayati, Kusnadi. 2021. Reproduction performance, morphometric and structure population of Kuntu buffalo (Bubalis bubalis Merr) in Kampar District, Riau, Indonesia. Biodiversitas 22: 3370-3377. Kuntu buffalo is one of the germplasm of Riau Province. This study aimed was to determine reproduction performance, potential output, population dynamics, and morphometrics of Kuntu buffalo in Kampar Kiri, Indonesia. The research was conducted in July-October 2019 with materials used in the study were 2.746 buffalo and 1.117 buffalo breeders. The research method used was a survey. The respondents from five locations were determined using a purposive sampling technique. The age at first mating of buffalo 42 ± 0.7 months, the S/C 2.6 ± 1.5 times, calving interval 15.3 ± 2.3 months and calving rate 55.59%. The reproductive efficiency of Kuntu buffalo 96.22%, a natural increase of 55.59%, the net replacements rates (male and female) were 289.60% and 446.59%, respectively and potential output of 39.24% was obtained. The population dynamics of the Kuntu buffalo from 2014 to 2019 experienced a growth of 48% with prediction of the population in 2023 is 7.277 heads. The average body size of male and female Kuntu buffalo is small. The conclusion of Kuntu buffalo reproduction is still efficient with the availability of substitute livestock exceeding the need of livestock and the natural increase of Kuntu buffalo population is very high.

<p>The purpose of this study was to determine reproductive efficiency, population dynamics, natural increase and estimated output of the Kuantan cattle in the Kuansing Regency, Province of Riau. A total of 311 Kuantan cattle and 99 Kuantan cattle farmers were used in this study through a survey study. Respondent samples were taken from seven districts. Data sampling using purposive sampling with survey methods. Data collection was carried out by interviewing farmers and observing and was analyzed descriptively. Parameters measured were reproductive efficiency, natural increase, estimated output and population dynamics of Kuantan cattle. Results showed that the reproductive efficiency of Kuantan cattle was 1.04%, natural increase 5.14%, the balance of male and female 1: 5, the value of male NRR 50% and female NRR 100.56%, total cattle out 18.69% and total incoming cattle 18.69%, output value 48.88% and estimated population dynamics 2.85%. In conclusion, Kuantan cattle reproduction has not been efficient with the natural increase of the Kuantan cattle was very low, and the replacement stock availability for male and female cattle has not been fulfilled. It is recommended not to release Kuantan cattle in the next 5 years to maintain population balance.</p>

Objective: The aim of this study was to compare the fetal biometric growth measurements (Head Circumference, Bi-Parietal Diameter, and Femur Length) between male and female fetuses on antenatal ultrasound in our population. Methodology: This was an observational study carried out in the Department of Radiology CMH Malir, Karachi and Ziauddin hospital, Karachi from July 2016 till July 2018 using non-probability sampling technique. A total of 510 pregnant women with second and third trimester were enrolled for the study. The biometric parameters of fetus i.e., Bi-Parietal Diameter, Head Circumference, and Femur Length were established through two-dimensional ultrasound. Chi-square and t tests were used to analyze differences in biometric parameters in both genders. Results: The study results showed significant differences in the Bi-Parietal Diameter and Head Circumference between male and female fetuses (p=0.006 and p=0.003, respectively). Mean Bi-Parietal Diameter in males was 71.47±13.70 and in females it was68.30±11.90cm, mean Head Circumference in males was 264.23±47.87and in females it was 252.03±44.91cm. It has also been observed that there was an insignificant difference in the femur length between male and female fetuses (p= 0.605). Mean femur length was 52.74±12.39 in males and 52.19±11.38 in females. Conclusion: This study concluded that male fetuses have considerably larger bi-parietal diameter and head circumference as compared to female fetuses however, no variation in femur length is observed in both genders. Keywords: Fetal Gender, Bi-Parietal Diameter, Head Circumference, Femur Length.

The present study was conducted to determine the early sex in turkeys by observation of the differences in body weight between male and female birds. A total of 30-day old black color unsexed poults having almost similar body weight at hatching were considered for the experimentation and housed at the Poultry Farm of Bangladesh Agricultural University, Mymensingh-2202, Bangladesh. All birds were reared up to 12 weeks of age under intensive management with supplementation of commercial broiler starter and grower feeds. Birds were reared under similar management conditions. Significantly higher (p<0.01) body weight was attained in male poults (104g/bird) than the female (90g/bird) at the end of 1st week of age. Similarly, at the end of 2nd week of age higher (p<0.01) body weight attained by male poults (198.31g/bird) than the female (162.13g/bird). At the end of 3rd weeks of age male poults attained higher (p<0.01) body weight (307.23g/bird) than the female (251.33g/bird). After 4 weeks of rearing, male turkeys attained significantly higher (p<0.01) live body weight (424.46g/bird) than the female turkeys (347.87g/bird). The weekly average body weight gains of male and female birds were 94.18g/bird and 76.5g/bird, respectively. Thus, the male and female birds were successfully identified on the basis of differences in their body weight. Weekly feed intake for both the male and female birds was also increased with their age. Up to 4 weeks of age, both the male and female poults consumed same amount of feed (753.46g/bird). The FCR of male and female poults differed non-significantly in 1st, 3rd and 4th week. On the contrary, in 2nd week of age the FCR of male poults (1.60) was significantly lower (p<0.01) than female (2.11). Survivability was 100% up to 4th week of age irrespective of sex of the poults. The birds were reared up to 12 weeks of age until to confirm their sex by observation of the phenotypic appearance. Results of the phenotypic observation of male and female birds correspondence hundred percent accuracy with the results obtained in body weight based differences between male and female birds. It is therefore concluded that farmers can identify male or female poults as early as first week of age on the basis of body weight differences. Progressive Agriculture 31 (3): 218-226, 2020

This is an attempt to investigate the teaching competencies of commerce teacher trainees. The main objectives of the study is find out whether there is any significant difference in the teaching competencies of commerce teacher trainees in respect of their gender, age, and medium studied. Sample of 200 B.Ed. trainees were selected by using purposive sampling technique. It is found that teacher trainees have low teaching competencies. It is revealed that there is significant difference in mean teaching competency scores of male and female, English and Malayalam medium teacher trainees. This study also revealed that there is no significant difference in mean teaching competency scores of trainees who are less than 22 years of age and above 22 years of the age group.

The present investigation is a comparative study in which a total of 564 tribal and non-tribal adolescent students of Jammu And Kashmir State were selected by stratified random sampling technique. The tribal and non-tribal students were compared for the relationships between academic achievement and scientific temper. Data collected by The Scientific temper scale (2008) by Showkat and Nadeem showed a significant relationship between academic achievement and scientific temper in non-tribal adolescents only. Further gender wise comparisons revealed that male and female students of non-tribal group had significant relationship between the two variables as compared to tribal group.
