Bangladesh Journal of Animal Science 2019-01-16T13:04:38+00:00 Professor Dr. Md. Ruhul Amin Open Journal Systems Official journal of the Bangladesh Animal Husbandry Association, Bangladesh Agricultural University, Mymensingh Productive and reproductive performance of Saanen goat at AZZahra farm of Sandakan in Malaysia 2019-01-16T13:04:38+00:00 MAMY Khandoker N Afini A Azwan <p>An experiment was conducted at AZ-Zahra Farm, Sandakan, Sabah, Malaysia to investigate the productive and reproductive performance of Saanen dairy goat. Body weight at different ages were collected once while birth weight was collected when does gave birth. On the other hand, milk production of each individual per day was received continuously for three months. The data on reproductive parameters such as length of estrus cycle, duration of estrus period, age at puberty, gestation length, age at first kidding, litter size, birth weight and kid mortality were noted. Descriptive statistics such as number, percentage, mean, standard deviation were performed. T-test was also conducted to know the statistical difference between the groups. Result demonstrated that body weight increases significantly (p&lt;0.01) with the advancement of the age. The highest daily milk yield was found in 2-3 years of age. Dam with multiple kids produced more milk than dam with single kid. Estrus cycle of Saanen goats was found 21 days, the average estrus period duration was 2.75 days, age at puberty was 8.33 months, first kidding age was 14.2 months and gestation period was 150 days on an average. With the increase of the age of dam litter size increased. Meanwhile average birth weight increased as age of dam increased from 2.85 kg in 1 year to 3.26 kg in 3 years. Male kids born heavier than females (3.23±0.62 vs. 2.75±0.58 kg) and single kids were heavier than twin kids (3.07±0.66 kgvs2.70±0.28 kg). Low mortality rate of kids was recorded in this study (6.4%). It can be concluded that the overall productive and reproductive performances of Saanen goat at AZ-Zahra farm were within the acceptable level and the variation recorded in different parameters is very much usual.</p> <p><em>Bang.

The data were collected through an interview schedule personally from 45 respondents in 3 villages of Bhaluka upazila who were involved in goat production. Parameters studied were check list for organic goat production likes origin, feeds and fodder, breeding, health care, living conditions and record keeping of livestock and factors related to organic goat production. In this study, about 100% goats were indigenous in origin. Among the farmers, 96% farmers used roadside grass and tree leaves whereas, only 4% farmers used cultivated fodder which was cultivated in their own land. 85% farmers used mixed feed which prepared by themselves. However, only 11% farmers used vitamin mineral supplementation.100% farmers used natural breeding method for goat breeding. About 91, 80 and 100% farmers practiced vaccination, deworming and castration method, respectively. About 84% farmers did not use hormone, antibiotic and growth promoter and 67% farmers removed sick or injured animals from healthy stock. About 100% farmers allowed access to outdoor and fallow land throughout the year. Only 31% farmers reared male and female goat separately and 60% farmers kept livestock record. In Bangladesh goat are reared in the conventional method where different inorganic substances are used by the farmers There are great potentialities for organic goat production in Bangladesh both for satisfying animal protein requirements and production of quality goat meat. For this, it is a prime importance to find out the present status and explore the potentialities of organic goat production in Bangladesh.</p> <p><em>Bang. J. Anim.

Day-old male broiler chicks (n=400; Cobb 500) were distributed randomly into four litter densities [T<sub>1</sub>, T<sub>2</sub>, T<sub>3</sub> and T<sub>4</sub>] treatments, each treatment had 5 replicates with 20 birds per replicate cage in a completely randomized design. Wood shaving was used as litter materials to a thickness of 5 cm, 8 cm, 11 cm and 14 cm on the floor of the pen. Birds were reared on the litter floor open-sided housing condition with <em>ad libitum </em>feed and water throughout the trail period. Data on feed intake (FI), body weight (BW), feed conversion ratio (FCR) and mortality were measured weekly. Litter sample was collected on day 42 to assess the nitrogen content (N<sub>2</sub> %), dry matter (DM%) and moisture level (%). Footpad dermatitis (FPD) and hock burn (HB) incidences were measured on day 42 to assess the leg quality of birds. Results demonstrated that litter thickness had no significant (P&gt;0.05) effect on FI, BW, FCR and mortality of broilers from d1-42 days. The N<sub>2</sub>, DM or moisture levels (%) of litter were also unaffected (P&gt;0.05) between treatment. Leg disorders such as HB and FPD were influenced (P&lt;0.01) by treatment. The incidences of HB and FPD were higher (P&lt;0.01) in T<sub>1</sub> and T<sub>2</sub> than other treatments. It can be inferred from our current study that, leg health may be deteriorated by using low density wood shaving without affecting growth and litter quality of broiler chickens.</p> <p><em>Bang. J.

The study was undertaken to investigate the variations in the chemical composition of MBM available in different feed markets of Chittagong, Bangladesh. Secondary data from one hundred ten different MBM samples were analyzed in triplicate for dry matter (DM), crude protein (CP), crude fiber (CF), ether extract (EE) and total ash (TA) in the Poultry Research and Training Centre laboratory of Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh during 21<sup>st</sup> October 2014 to 2<sup>nd</sup> December 2016. Data were collected, compiled and analyzed. Results indicated that, there were wide ranges of variations in the chemical compositions for different parameters. DM varied from 91.9 to 98.7% and CP varied from 18.5 to 74.5%. Similarly, CF varied from 1.1 to 2.9% and EE varied from 7.5 to 45.0%. TA varied from 4.8 to 33.6%. There was a strong negative relationship between CP and TA (r=-0.831; R<sub>2</sub>=0.691; P&lt;0.001). However, DM and TA were positively correlated (r=0.374; R<sub>2</sub>=0.139; P=0.003). It was concluded that, chemical composition of MBM is widely variable. Wet chemistry analysis is suggested before inclusion of MBM in the diets of dairy, poultry and pet animals.</p> <p><em>Bang. J.

The experiment was conducted at Bangladesh Livestock Research Institute (BLRI) for a period of 35 days. A total of 5 types of TMR was prepared on fed basis with different roughage and concentrate ratios as T<sub>1</sub>=70:30, T<sub>2</sub>=60:40, T<sub>3</sub>=50:50, T<sub>4</sub>=40:60, and T<sub>5</sub>=30:70. Five cannulated bulls with an average live weight ranging from 200 to 300 kg and approximately 18 months of age were selected for the experiment. The present study indicated that there was no significant difference in pH among different treatment groups. Concentration of total volatile fatty acids (TVFAs) was highest in T<sub>2</sub> group which was found to be increased up to 12 h after feeding, then gradually decreased up to 24 h. Concentration of total nitrogen (TN), ammonia nitrogen (NH<sub>3</sub>-N), non protein nitrogen (NPN) and protein nitrogen (PN) were highest in T5 group. Concentration of total nitrogen (TN), ammonia nitrogen (NH<sub>3</sub>-N) and protein nitrogen (PN) were gradually decreased up to 12 h after feeding but then gradually increased trend observed up to 24 h. Concentration of non protein nitrogen (NPN) was found to be decreased gradually from 0 h up to 24 h after feeding. The result also indicated that rumen NH<sub>3</sub>-N was positively correlated with TN intake of the animal. It can be concluded from the present study that the TMR provided better rumen environment at different hours of digestion could be used for better rumen fermentation. The best combination of roughage to concentrate ratio (30:70) was in T<sub>5</sub> group for better N utilization to achieve maximum performance through proper feeding which might reflect the gross return of cattle production.</p> <p><em>Bang.

Shoti from Bangladesh Agricultural University campus was collected and sorted on the basis of white color of the rhizome. Then they were chopped into pieces, sun dried and pulverized in a flour mill. Aliquot samples were autoclaved at 120<sup>0</sup>C under 15 lb of pressure per square inch for 30 min. Autoclaved samples were stored in tightly lid contained for future use. 3 One hundred -day-old Cobb 500 broiler chicks were reared on the floor and a total of 24 growing broilers, 4 birds in each group were weighed on d 15 Two broilers were placed in each cage. There were a total of four experimental and two control (positive and negative Non-protein control) diets. Diets were fed <em>ad libitum </em>from day 15 to 33days. Body weight, feed intake, feed refusal and fecal weights were recorded every day. Cumulative feed efficiency per bird was calculated as the ratio of weight gained to feed consumed. Dry matter of excreta was determined from the last 10 d of feeding trial by drying aliquots of every day’s droppings by drying for 6 h at 1050C. On d 19, birds were bled to death. Immediately after slaughter, the carcasses were examined systematically. The chemical composition of Shoti meal showed that it is low in protein, fat and trace minerals and therefore mainly a source of energy. The bulk of the tuber (75 percent) consists of carbohydrates, made up of 10.6% fiber, and 64.9% nitrogen free extracts (NFE). A peculiarity of <em>Curcuma </em>rhizome meal contains high level of ash (9.9%) on DM basis. The results showed that at day 33, the weight of the broiler chicken fed shoti 100g, 200g, 300 g and 200g (autoclaved shoti meal)/ Kg diet was significantly different from the weight of the chicken fed on a maize-soybean diet. The birds given shoti meal consumed less feed than those provided with a maize diet. Feed efficiency or weight gain to feed ration over 19-d period was the poorest when fed 300 g Shoti/ Kg diet. Intake picked up when the shoti meal was incorporated after having been autoclaved and there was slight improvement in body weight gain as compared to that of other Shoti fed group. However, feed efficiency and body weight gain as % of initial weight remained significantly lower than the maize-soybean control. The inclusion of Shoti meal generally had an adverse effect on the apparent dry matter digestibility compared with the control diets. The group fed autoclaved shoti meal had a similar effect and the true N digestibility was the lowest when compared to those of control fed on maize-soybean meal. Thus, physical treatment like using autoclave, caused further reduction of digestibility of its N. Lipid digestibility was reduced by ingestion of shoti meal. Since the diets were isocaloric, after correction for the apparent endogenous lipid losses, which were obtained from the results of non-protein control feeding, the net faecal losses was around 66.2% of the ingested lipid against control diet fed birds.</p> <p><em>Bang.

The ovary was grasped by inserting left hand through the rectum and the follicles were visualized by inserting a sectorial probe through the vagina. Ovarian follicles were visualized and recorded by counting on the screen of ultrasonography machine. All visible follicles (&gt;2.0mm) were counted and graded as small (&lt;3.0mm), medium (3.0 to 8.0mm) and large (&gt;8.0mm). The follicles were measured 3 times at a 3-day interval period without considering the stage of the reproductive cycle of the experimental animals. During this experiment, a total of 137 follicles (66 in Heifers and 71in cows) were observed from 10 heifers and 10 cows. The corpus luteum was observed either in the left or right ovary of 25.0% heifers and 35.0% cows. In heifer, 40.91, 45.45 and 13.64% of the observed follicles were belonged to small, medium and large groups, respectively. The percentage of small, medium and large follicles in the cow ovaries were 54.93, 39.44 and 5.63% accordingly. The number of follicles in an ovary did not vary (P&gt;0.05) between right and left ovary of a heifer or cow. The diameter of the largest follicle on the ovary was smaller (P&lt;0.05) in heifer (9.43±0.34mm) compared to cow (11.2 ± 0.73mm). This information will be helpful during aspiration of ovarian follicle from donor cows.</p> <p><em>Bang. J. Anim.
