An investigation was made on the performance of 144 unsexed Van Cobb broiler chicks from 21 days to 42 days of age. The chicks were fed on soybean meal (SM) based iso-nitrogenous and iso-energetic diet incorporating phytase with the levels of 0.0, 0.50, 1.00 and 1.50 g/kg diet for better utilization of the basal diet. The growth rate, feed intake, feed consumption, dressing yield and profitability increased as the level of phytase supplementation increased and the level of phytase had no effect on survivability. The addition of phytase seemed to be effective to overcome the antinutritive effect of phytate phosphorus and non-starch polysaccharides (NSP) on broiler performance. Therefore, it was concluded that 1.50 g/kg phytase may be incorporated in SM based broiler diet for profitable production. |

A factorial bioassay was made to evaluate 4 different levels of exogenous saponin (S); 0 mg (So), 25 mg (S1), 50 mg (S2) and 75 mg (S3) per kg and also a combination (SC) of 50 mg saponin plus 50 mg L-carnitine (S4) per kg maize-soybean meal based basal diet during the late autumn. In all, 5 experimental diets being iso-nutritive (as per NRC, 1994 recommendation) but for variable in presence and contents of saponin and L-carnitine were prepared. 8-day old male broiler chicks (n=150, Starboro) were distributed randomly into 15 groups of 10 chicks in each housed in separate pen of littered floor. Three such groups received each of 5 test diets ad libitum as mash up to 8 weeks of age. The plenty of water was made available to all chicks during the experimental period. It was found that S2 diet significantly improved body weight gain (BWG) during growing (8 days to 3 weeks) period when compared with S0, S1, S3 and S4. Dietary S and SC had no significant (p>0.05) effect separately and jointly on feed efficiency, protein efficiency and performance index. But S3 and S4 diets reduced abdominal fat significantly (p<0.05), while only S3 significantly (p<0.05) increased tastes weight. S and SC added all diets significantly (p<0.05) reduced liver, gizzard and thyroid size with little enlargement of spleen size compared to S0 fed group. Finally, it was concluded that 75 mg (S3) per kg exogenous saponin could be used as feed additive in broiler diet to improve growth and carcass quality. |

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 carcass characteristics
and meat yield studied using a total 20 number of cage reared spent
hens of White Leghorn (WLH), White Rock (WR), Rhode Island Red (RIR)
and Barred Plymouth Rock (BPR). There were a significant different (p< 0.05)
between breeds with live weight and dressed weight although it differ
breed to breed. In case of dressed weight it is observed higher in RIR
intermediate in BPR & WR and lower in WLH. Shank length, head weight,
liver weight and gizzard weight were statistically non-significant between
breeds. Shank length was statistically non-significant between breeds
but shank weight was highly significant between them and highest in
WR, intermediate in RIR & BPR but lowest in WLH. Viscera loss is higher
in WLH then RIR and WR, BPR are in almost similar and the similar trained
was found for feather loss and blood discharge. The result exhibits
that the RIR carcass is the best, BPR and WR are in second position
and the lowest is WLH in qualitative or quantitative measure not only
for heavy breed but the total loss (viscera, feather and blood) is the
lowest in comparison to the other three breeds. On the contrary, correlation
between dressed carcass weight and abdominal fat was estimated and highly
correlation was found in WLH followed by BPR, RIR and WR. If dressed
carcass weight increase 1 (g) then abdominal fat increase by 0.2136(g),
0.1297(g), 0.1819 (g) and 0.0591 (g) respectively for WLH, BPR, RIR
and WR. Finally it can be concluded that the RIR carcass is the best
in terms of quality and quantity. The WR & BPR are almost in similar
holding second position and the lowest is WLH. |

An experiment was conducted
with 128, 7 days old Vencobb broiler chicks to study the effect of feeding
different protein concentrates (Jasoprot, Provita, Fishpro) on the performance
of broiler. The dietary treatment was fish meal based control diet where
fish meal was replaced by different protein concentrates. The live weight
of broilers fed different protein concentrates differed significantly
(p< 0.01) at 4, 5 and 6th weeks of age. The live weight gain during 2-6
weeks in Jasoprot was higher than other treatments. Broilers fed Josoprot
diet had better feed conversion ratio than other dietary treatments.
At 6 weeks of age, the production number in Jasoprot diet was significantly
(p< 0.01) higher than other dietary treatments. Similar trend was observed
in performance index. Survivability was similar in different treatments
during the experimental period. Net profit was higher (p< 0.01) in Jasoprot
diet as compared to other treatments. It can be concluded that protein
concentrates available in the market could replace fish meal from broiler
diet with satisfactory performance. However, Jasoprot seems to be the
best as protein concentrates studied in respect of broiler performance
and financial return. |

Local chickens dominate
poultry production in Bangladesh. For this reason, an investigation
was conducted to determine the existing production system and production
performance of native chicken in the Sylhet areas of Bangladesh. Data
were collected from 180 households of 6 villages of Sylhet district
in Bangladesh. In Sylhet mainly poor families, who have arrived from
outside and are landless rear poultry. Most of the households (58.33%)
had 0-15 chicken. Most of the families (75%) reared their chicken in
combined house with duck. Materials used for housing were similar to
other parts of the country. Mainly female members were involved in poultry
rearing. About fifty percent farmers got on an average less than 70
eggs per year per bird. A few farmers (5.56%) informed that they had
collected more than 130 eggs from a bird in a year. In most of the cases
(47.22%) the length of clutch was less than 20. Interval between two
clutches was found in highest percentage(42.22%). Highest egg production
was observed in winter season (52.78%) followed by summer, spring and
late autumn. Maximum (60%) farmer had vaccinated their birds and 55%
farmers got service from Department of Livestock Services. |
