  Twenty four indigenous autosomal dwarf hens were selected and divided equally into 3 groups. Rhode Island Red, White Leghorn and Fayoumi Cocks, 2 for each were placed to each group respectively for breeding. Sixty eggs were selected from each group and hatched in a forced draft incubator. Among those, 36 healthy day-old chicks from each group were selected and reared up to 20 weeks of age. The chicks were identified as normal and dwarf genetic groups at 8 weeks of age. The aim of this study was to observe the reproductive parameters of crosses and parameters related to the meat yield of normal and dwarf genetic group of crossbred chicken under farm condition. Fertility, hatchability on total eggs and hatchability on fertile eggs of cross B (95.57; 68.71; 72.41) were higher (p<0.01) than cross A (93.44;63.44;67.62) and cross C (90.92;60.89;67.19). Dead-in-germ and dead-in-shell were statistically higher (p<0.01) in cross C than cross A&B. Reduced adult body size, improved feed conversion and higher livability were found in all genetic groups of dwarf crossbred. Among those, White Leghorn was found as the best one also considering its different dressing yields. Advantages of adw gene in terms of a good scavenger could better be exploited by introgressing in exotic smaller breeds like White Leghorn from indigenous dwarf chicken.

  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 data of the present study were collected from Bangladesh Milk Producer`s Co-operative Union Limited (BMPCUL) at Baghabarighat, Sirajgonj to investigate the bull performance among various seasons through semen quality and 30-day non return rate. To evaluate the seasonal variation on semen quality and bull fertility the experimental period was divided into three seasons; a) Summer season (March to June), b) Rainy season (July to October) and c) Winter season (November to February). Data on 245 ejaculates and 12,750 services of almost same aged 5 Sahiwal bulls (B1, B2, B3, B4 and B5) over a period of 5 years were collected from Animal Breeding section and Cattle Feed Unit of BMPCUL. The performance of five bulls was compared in three seasons i.e. summer, rainy and winter and summer was observed to be the best for most parameters studied. Seasons had significant (p<0.05) effect on semen volume, initial and post- thawing sperm motility and pH of semen but not on sperm motility of diluted semen and fertility. The significant (p<0.01) bull x season interaction was noticed in semen volume, sperm motility at initial and post-thawing stages, pH and fertility but not on sperm motility of diluted semen.
