XPRESSIONAL PATTERN OF GELATINASE MATRIX METALLOPROTEINASE (MMP) IN GOAT UTERUS Rahman, Al-Nur Md. Iftekhar Executive Summary: Homeostasis of the extracellular matrix (ECM) is maintained, in part by, the action of a specific class of proteolytic enzymes known as the matrix metalloproteinases (MMPs). The endometrium, which lines the largely muscular uterine body, is a highly specialized tissue that has evolved to support the dynamic events required to establish and maintain pregnancy. Tissue remodeling of endometrium is broadly defined as the structural reorganization or renewal of living tissue, which depends on the breakdown and reformation of the ECM. The aim of this study was to examine the impact of hormonal influence on the expression of matrix metalloproteinases (MMPs) in goat endometrial tissue. The goat uterus was collected from local abattoir in Dhaka city from July-2021 to March-2022. In the laboratory, the tissue was separated from caruncular and intercaruncular region of the goat endometrium. The endometrial tissue was used for gelatin zymography to identify MMP proteins. Zymograms of the tissue supernatant showed that MMP-9 was rarely expressed in goat endometrium and both pre and mature form of MMP-2 are differentially expressed in estrous group. Total MMP-2 protein expression was found higher in caruncular tissue in estrous cycle group. Caruncular tissues are better able to react to hormonally driven MMP production. Reproductive hormones estrogen (E2) and progesterone (P4) significantly influenced the clearance of MMP-2 since E2 and P4 is the prime hormone of the follicular and luteal stage respectively. In conclusion, E2 and P4 probably control the endometrial remodeling through MMPs in the goat endometrium.

EFFECTS OF SUPPLEMENTATION OF CINNAMON AND TURMERIC POWDER ON PERFORMANCE AND QUALITY OF QUAIL EGGS Akter, Mofassara Executive Summary The experiment was conducted to investigate the effect of mixed supplementation of turmeric and cinnamon powder on the performance and egg quality of Japanese quail. This study consisted of five treatments with four replications of 20 quails each established in a completely randomized design. The treatments consisted of T0 (control), T1 (10 g cinnamon + 10 g turmeric)/kg of feed, T2 (10 g cinnamon + 20 g turmeric)/kg of feed, T3 (20 g cinnamon + 10 g turmeric)/kg of feed, and T4 (20g cinnamon + 20g turmeric)/kg of feed. Parameters measured included feed intake, body weight, feed conversion ratio, egg production, egg weight, yolk weight, yolk color index, egg white weight, eggshell weight, and egg cholesterol level. In addition, the percentages of quails that reached maturity at 42 days of age were recorded. The obtained results indicated supplementation of the mixture of turmeric and cinnamon reduced feed intake and significantly (P0.05) different in different treatments. Dietary supplementation with the mixture of turmeric and cinnamon significantly increased egg production percentage, yolk weight and significantly (P<0.05) decreased egg yolk cholesterol level. Therefore, it is suggested that the dietary inclusion of 20g turmeric and 20g cinnamon powder per kg of feed can promote the performance and egg quality of Japanese quails.

EFFECTS OF FEEDING GARLIC ON GROWTH PERFORMANCE AND IMMUNITY OF BROILER Akter, Mofassara Executive Summary The experiment was conducted to evaluate the effects of using different levels of garlic on production performance, carcass traits, immune parameters, and cholesterol level of commercial broiler. A total of 240 "Lohman Meat (Indian River)" strain chicks were separated into 6 experimental groups, each with 4 replications of 10 chicks. The treatments were T 0 = control (basal feed), T 1 = basal feed + antibiotic, T 2 =0.5% garlic, T =1.0% garlic, T 4 =1.5% garlic and T =2.0% garlic. Throughout the trial period, body weight, feed consumption, and FCR were recorded. At the end of the experiment, cholesterol levels, immunological parameters, and carcass features were also examined. The average live weight, body weight gain and dressing % were significantly (P<0.05) increased in the different doses of garlic-treated groups than in the control and antibiotic-treated groups and the highest performance was observed with 2.0% garlic-treated groups. Birds fed different levels of garlic showed improved FCR non-significantly (P>0.05). The effects of different levels of garlic on carcass and some internal organs were measured and results show that feeding broilers with 2.0% garlic have significant effects (P<0.05) on the breast, thigh, wing, liver, neck, heart, giblet while it appeared insignificant on (P>0.05) back, drumstick, gizzard, intestine, spleen and bursa. Significant (P<0.05) difference was detected for immune parameters i.e. WBC, lymphocyte and granulocyte in garlic-treated groups than in the control and antibiotic-treated groups which indicates better immunity in garlic-treated groups. Additionally, compared to the control and antibiotic groups, supplementing with different levels of garlic significantly reduced the levels of total cholesterol, triglycerides, and LDL with a significant (P<0.05) increased amount of HDL. The best outcomes were obtained with a supplement of 2.0% garlic-treated group. Therefore, the addition of 2.0% garlic to broiler ration as a substitute for antibiotics and a cholesterol-lowering agent can be guided to prevent risks to human health.

PERFORMANCE OF CROSSBRED CATTLE AT DIFFERENT AREAS OFDHAKA DISTRICT IN BANGLADESH

PERFORMANCE OF CROSSBRED CATTLE AT DIFFERENT AREAS OFDHAKA DISTRICT IN BANGLADESH Asad, Lam Yea The study was conducted to see the performance of different crossbred cattle likely Sahiwal and local crossbred (SL×L), Holstein and Sahiwal crossbred (HF×SL), and Holstein crossbred (HF×HF). A total 120 crossbred cows were selected from different area of Dhaka district. There was a significant difference (p<0.05) of lactation length, age at puberty, age at first service, age at first calving, dry period and days open but no significant difference (p>0.05) was found in service per conception and calving interval of different crossbred cattle. It was observed that birth weight of calf SL×L, HF× SL and HF × HF was 20.92±1.83 kg, 26.55±2.43 kg, and 37.35±3.79 kg respectively. Mean milk yield per day for SL×L, HF×SL, HF×HF crossbred cattle were 4.45±0.79, 15.73±1.72, 25.6±3.16 liters respectively. Lactation yield was higher 6944.05±970.41 liters in HF×HF crossbred cattle. Age of puberty was shorter 18.12±1.18 months in HF×HF cross and longer 27.47±1,43 months in SL×L crossbred cattle. The reproductive performance of HF×SL crossbred needs minimum service per conception (1.27±0.55) and SL×L crossbred need maximum service per conception (1.37±0.74). Calving interval was higher 15.87±1.09 months in HF×HF crossbred cattle. Dry period was lower 79.5±13.24 days in HF×HF crossbred cattle. From the above perspective it could be concluded that HF×HF crossbred cows may be suitable for profitable farming in Bangladesh but herd life and life time productivity is one of the most influential factor for profitable dairy farming. However, further study with larger sample sizes covering more different management systems would be required to describe a better inference in this consideration.
