SYNERGISTIC EFFECT OF NEEM LEAF (Azardirachta indica) AND SWEET POTATO (Ipomoea batatas) ON BROILER PRODUCTION MD. ALAUDDIN A total of 120 day old “Cobb-500” broiler chicks were reared in the poultry farm of Sher-e-Bangla Agricultural University, Dhaka, to evaluate the growth performance of broiler fed diet containing neem leaf powder (NLP) and sweet potato powder (SPP). Chicks were divided randomly into 4 experimental group with 3 replications of each group. Each replication contains 10 chicks. One of the 4 experimental group was fed with antibiotics in basal diet and considered as control group (T 0 ); the remain three groups were fed diet with (2 g NLP + 2 g SPP)/kg feed (T 1 ), (2 g NLP + 4 g SPP)/kg feed (T 2 ), and (2 g NLP + 6 g SPP)/kg feed (T 3 ). Experiment revealed that the relative final live weight (g) of broiler chicken in T 3 (1875.4 a ±23.27) group were significantly (P<0.05) higher than other groups. Feed conversion ratio of T 1 (1.3133 b ±.008) was significantly (P<0.05) better than other groups including control T 0 (1.3367 a ±0.03). Feed conversion ratio in T 3 (1.3333 a ±0.03) was also better than control group T 0 (1.3367 a ±0.03) without any statistically significant (P<0.05) differences. The dressing percentage of broiler were 66.66 b ±0.82%, 67.30 ±2.07, 67.64 a ±1.3% and 64.68 c ±1.33% in T 1 ,T 2, T 3 and T 0 respectively. All treatment groups were significantly (P< 0.05) higher than the control group. The relative weight (g) of liver were 41.0 a ±.57, 41.0 a ±.57, 45.6 ab ±5.78 and 54.3 b ±2.02 in T 0 and T 3 respectively; the relative weight of heart were 9.817±.14, 10.167±.35, 10.100±.56 and 10.933±.31 in T 0 , T 1 ,T 2 and T 3 respectively; the relative weight of gizzard 37.167±.52, 38.033±1.92), 39.000±1.41 and 40.400±.15 in T 0 , T 1 respectively. The weight of liver, heart and gizzard in T 3 were significantly (P<0.05) higher than the other groups including control. The feed consumption; body weight gains (g); survivability rate; carcass weight; weight of intestine; immune organ (spleen) and flock uniformity of broiler chicken were no significant (P>0.05) difference among the treatment and control groups. The profit per bird were 57.7367 a ±.09, 57.9233 a ±1.33, 56.0067 a ±1.36 and 62.3933 b ±1.33 in T 0 respectively. T 3 was significantly (P< 0.05) higher than all groups including control group. The experiment recommended that neem leaf powder and sweet potato powder can be use at the concentration of (2 g NLP + 6 g SPP)/kg feed in broiler production.

COMPARISON OF GROWTH PERFORMANCE OF BLACK BENGAL GOAT IN DIFFERENT REGIONS IN BANGLADESH HOSSAIN, MD. ANWAR The Black Bengal goat is known as Poor man’s cow due to its high prolificacy, quality meat and famous skin. It is one of the prominent goat breeds in our country. Making better performance to grow higher profit from this goat is the key to strengthen local economy. Thus the present study was carried out the factors affecting growth of this goat. The data of 120 goats were collected from Dhaka, Kishoreganj and Sunamganj districts to analyze the effect of different locations on growth performances. The growth performance of goats was found the best in Dhaka followed by Kishoreganj and Sunamgonj in terms of weight at birth (0.97±0.02 vs 0.90±0.02 & 0.82±0.02); 3 months (5.51±0.05 vs 4.99±0.08 & 4.93±0.08); 6 months (8.71±0.08 vs 8.07±0.07 & 7.64±0.06) and 12 months (12.97±0.08 vs 12.34±0.11 & 11.60±0.05). The study revealed that kids have grown well in Dhaka than other two districts irrespective of sex. Average weight of male and female in Dhaka was at birth (0.96±0.03 & 0.99a±0.03); 3 months (5.66a±0.03 & 5.24a±0.09); 6 months (8.93a±0.09 & 8.29a±0.08) and 12 months (13.18a±0.08 & 12.58a±0.10). The growth performance was higher in Dhaka in different types of birth i.e. sigle, twins and triplets. Kids of Dhaka were found better in all parity of dam, Kishoreganj in middle and Sunamoganj with lower growth. The kids in Dhaka grown well and mixed trend recorded in other two districts. According to above discussion, growth performance is better in Dhaka by geography, sex, type of birth, parity of dam and season than Kishoreganj and Sunamganj.

NON-GENETIC FACTORS AFFECTING SEMEN QUALITY OF BULLS RAHMAN, MD. HAFIZUR Cattle are the main livestock species in Bangladesh having over 25 billion population. Artificial insemination is mainly used for breeding. In the present study, a total of 235 ejaculates from 26 bulls were analyzed to evaluate the non-genetic factors of semen quality of bulls in the Central Cattle Breeding and Dairy Farm (CCBDF). Among three age groups, adult bulls (72-96 months) produced the highest volume (11.65±0.37ml) and concentration (1372.4±53.94) whereas mass and forward movement was higher in mature (3.43±0.03) and adult (69.44±0.55) respectively. Bull having medium weight (500-750 kg) produced more volume of semen (10.39±0.26ml) but concentration and mass movement was higher in light (up to 500 kg) weight group (1382.1±49.37 and 3.52±0.05) while forward movement recorded higher in heavy weight group (69.72±0.55). Seasonal variation was not significant in the study. Early matured (18-24 months) bulls produced more volume (10.15±0.23ml) but late matured (24-36 months) bulls have more concentration (1402.7±43.14), mass movement (3.46±0.04) and forward movement (68.54±0.45). Thus the study showed that, adult bulls having the body weight up to 500 kg (light) from late matured bulls will produce quality semen in any season in terms of volume, concentration, mass and forward movement.

COMBINED EFFECT OF NEEM LEAVES AND APPLE CIDER VINEGAR ON GROWTH AND ANTICOCCIDIAL EFFECT IN BROILER KHUNDOKER, LIMA This study was conducted to find out the efficacy of neem leaves and apple cider vinegar on growth and anticoccidial effect in broiler. A total of 120-day old Indian River-Lohmann meat broiler chicks were divided into 4 experimental groups with 3 replicates as 10 chicks in each replication. One of the 4 experimental group fed normal diet without neem leaves and apple cider vinegar (ACV) was as control and the remaining three groups fed diet with neem leaves were T 1 (2g/Kg feed), apple cider vinegar (ACV) T 2 (5ml/L drinking water), combined neem leaves and apple cider vinegar (ACV) T 3 (2g/Kg feed & 5ml/L drinking water). During the experimental periods of 4 weeks, feed intake, body weight gain, feed conversion ratio (FCR), flock uniformity, survivability & coccidial oocyst count were calculated. Growth performance parameters & coccidial oocyst count were significantly (P˂0.05) affected by experimental diets. Birds fed combined neem leaves and apple cider vinegar (ACV), T 3 gained superior body weights (1734.00±16.37g) compared to control (1581.00±9.54g), T 1 neem (1647.33±10.48g) and other dietary treatments. The mean body weight gains (g) at the 1st, 3rd and 4th week of different treatment groups were significantly higher (P˂0.05) than control group. The groups fed diets containing combined neem leaves and apple cider vinegar feed (T 3 ) had better FCR (1.32±0.01) compared to control (1.51±0.00). Highest (100%) survivability was found in T 3 group than control (90%) group. The inclusion of different dietary treatments had significant (P˂0.05) difference on coccidial oocyst count. However, T 3 group had the better (3.00±1.15) oocyst count compared to control (22.33±1.45). It is concluded that combined neem leaves & apple cider vinegar can be included in broiler diet for better performance with better FCR & lower coccidial oocyst count.
