  A total of 63 day-old straight run Layer chicks up to 45 weeks of age on 3 isonitrogenous and isoenergetic diets D1 (6% PC+ 0% SWP), D2 (0% PC+ 6% SWP), and D3 (0% PC+ 8% SWP) were fed to observe the effect of dietary SWP on growth and egg production performance. This study revealed that profitability, growth and egg production performance of RIR pure line were significantly (P< 0.01) higher in D2 dietary treatment groups as compared to D1 and D3 treatment. No significant difference (P< 0.05) in livability was found which could be attributed to the dietary SWP levels. Feed cost/kg was gradually declined on increasing dietary levels of SWP. The efficiency by the birds receiving SWP were better as compared to the control. The result of this study demonstrated that cheaper SWP could be an excellent substitute of costly protein concentrate in formulating diets for layers leading to increase profitability.

  The research was carried out at the Animal Breeding and Genetics Laboratory under the Department of Animal Breeding and Genetics, Bangladesh Agricultural University, Mymensingh, Bangladesh. It was conducted with a view to establish some relationship between ovarian condition in terms of the presence or absence of corpus luteum and morphological quality of the COCs as well as the relationship between follicular diameter and quality of COCs. Significantly highest (p<0.01) number of follicles was found in type III ovaries. The number of follicles measuring 2-6 mm diameter was observed to be significantly higher (p<0.01) in type III than type II and type I ovaries. Moreover, grade A and grade B COCs were significantly highest (p<0.01) in number in 2-6 mm diameter follicles. It was established that cumulus cells surrounding the oocytes favour to a less or greater extent the IVM (In vitro maturation), IVF (In vitro fertilization) of oocytes and subsequent IVC (In vitro culture) of zygotes. On the basis of the study, it is concluded that type III ovaries having no corpus luteum may be suggested for obtaining good quality Cumulus-oocyte-complexes (COCs) in experiment for IVM, IVF and subsequent IVC.

  The experiment was conducted to compare the relative efficiency of homo and heterospermic insemination in respect of fertility judged by conception and calving rate. Spermatozoa from three different breeds of bull namely Holstein Friesian (HF), Red Chittagong (RC) and Sahiwal (SL) were mixed in equal number and preserved for 3 days and inseminated at different days. In this study 168 cows were inseminated and 42 of them were inseminated with heterospermic semen containing equal numbers of spermatozoa from a HF, a RC and a SL bull. After calving the paternity of calves was established by comparing coat colour and conformation. Difference between homo and heterospermic insemination on conception and calving rate was not significant (p>0.05). The heterospermic conception and calving rates were 80.95 ±0.07 and 64.29 ± 0.08%, with the homospermic rates being 66.67 ±0.04 and 50.79 ±0.04%, respectively. The conception and calving rate from heterospermic insemination was found insignificantly (p>0.05) different from that of homospermic insemination separately at first, second and third day of preservation. Conception rates of homo and heterospermic insemination at first day were 76.19 ±0.07 and 85.71 ±0.12%, respectively. The corresponding values at third day were 59.52 ±0.07 and 78.57 ±13%. Calving rate of homo and heterospermic insemination at first day were 57.14±0.08 and 64.29 ±0.13%, respectively. The corresponding values at third day were 45.24 ±0.08 and 64.29 ±0.13%. The numbers of offspring (12:8:7) sired by the three bulls (HF: RC:SL) after using heterospermic semen did not differ significantly from an assumed 1:1:1 ratio (χ2 = 1.55: p>0.05). The sex ratios among calves from heterospermic insemination (15♂ .12♀) also did not differ significantly (χ2 = 0.34: p>0.05) from 1:1. From the above results, it was concluded that heterospermic insemination did not however, show any significant superiority in conception and calving rate in cows compared to homospermic insemination. However, heterospermic insemination offers no apparent risk to co-operating farmers, since overall conception and calving rate were either numerically higher or at least equal to that obtainable from homospermic insemination.
