Study on the effect of feeding different levels of energy in compound Pellet on performance of growing black Bengal Goat

Three different complete compound pellets containing different levels of energy, viz. SE (standard energy, ME content 10.28MJ/kg DM as per NRC, 1981), LE (low energy, ME content 9.25MJ/kg DM) 10% less ME and HE (high energy, ME content 11.30MJ/kg DM) 10% high ME than SE respectively, were prepared and fed to three groups of growing Black Bengal goats for evaluating feeding value. Completely randomized design was followed in the experiment. The effect of different levels of energy containing pellet on performance of goat was varied. Both dietary group SE and HE showed higher (p<0.01) weight gain, total CPI, total MEI, and better (p<0.05) FCR and PCR than dietary group LE and only dietary group HE showed higher (p<0.05) total DMI, MEI 100kg-1 LW d-1 and MEI kg-1W0.75 d-1 than LE and DMI kg-1W0.75 d-1 than SE and LE. Higher (p<0.01) digestibility of DM, OM, ADF, NDF and (p<0.05) CP and CF was observed in SE and HE and digestibility of NFE in HE was higher (p<0.01) than SE and LE. On the other hand, higher (p<0.05) digestibility of EE was observed in SE and LE. Digestible crude protein, TDN and D value were higher (p<0.01) in SE and HE. Digestible EE was highest (p<0.01) in LE and lowest in HE but digestible NFE was highest (p<0.01) in HE and lowest in LE. Higher (p0.05) nitrogen retention was observed in SE and HE. Meat yield, selling price of meat, and total price was highest in HE and both SE and HE showed higher (p<0.01) value of the parameters than LE. Total rearing cost was highest (p<0.01) in HE and lowest in LE. Higher (p<0.05) net profit was obtained from SE and HE than LE. There was a positive correlation between increase of energy in dietary pellet and performance. It can be concluded that high energy containing pellet may be used for commercial Black Bengal goat production in stall feeding

Performance of growing black Bengal Goat Fed compound Pellet of different diameters

An experiment was conducted at Animal Nutrition Laboratory, Bangladesh Agricultural University, Mymensingh to observe the effect of different diameters of pellet diet on the performance of Black Bengal goat. Three diameter of a compound pellet diet such as D10, D8 and D6 (D10-10mm, D8-8mm and D6-6mm) were prepared according to NRC (1981) nutrient requirement and fed to goats of three groups. Insignificantly highest weight gain was observed in D10. Total Dry matter intake (kg), total crude protein intake (kg), metabolizable energy (MJ) intake (total, 100kg-1 LW d-1, kg-1W.75 d-1) and MEI/LWG (MJ/kg) were gradually increased with the decrease of pellet diameter but the difference of the parameters among the treatment groups were not significant (p>0.05). Both DM and CP intake (100kg-1LW d-1, kg-1W.75 d-1) were also increased with the decrease of diameter where D6 showed significantly (p0.05) CP and ADF digestibility value than D6. Digestibility of CF was highest in D8 but both D10 and D8 showed higher (p0.05) CP and D value in D10 and D8 than D6. Though nitrogen intake, outgo in feces and excretion in urine was highest in D6 and nitrogen retention was highest in D10 but the difference among the treatments was not significant (p>0.05). Dressing percentage, meat yield, price of meat, total sale price was insignificantly higher (p>0.05) in D10 and D8 and feed cost, total rearing cost, cost per kg weight gain and per kg meat yield was insignificantly higher (p>0.05) in D6. Highest profit was found in D10 and lowest in D6 and the difference was huge (Tk. 262.51) but did not differ significantly. It can be said that pellet with 10mm diameter may be used for economic goat production in stall feeding system

Effect of non genetic factors on productive traits of Black Bengal goats

Accumulated five years data on 197 kids of 15 Black Bengal bucks in the nucleus breeding flock of Black Bengal goats were analyzed for the study of production traits. The traits considered were birth weight, weight at every 3- month interval up to 12-month, semen characteristics and milk yield. Semen parameters were evaluated from 450 ejaculates of 15 Black Bengal bucks collected twice a week by artificial vagina method and daily milk yield of Black Bengal goats were estimated from the analysis of 57 lactation records of 30 does. The significance of fixed effects sex of kid, parity, litter size, season, age, body weight and scrotal circumferance were analyzed using least-squares analyses of variance of the general linear model (GLM) procedure of the Statistical Analysis System (SAS, 1998). Least-squares means for body weights at birth, 3, 6, 9 and 12-month of age were 1.3, 4.8, 8.0, 11.1 and 14.0 kg, respectively. Body weights at 3, 6, 9 and 12-month of age except at birth were affected by the sex of kids (p<0.05). Type of birth and parity of dam had the significant affect (p<0.05) on birth weight, whereas season of birth had significant (p<0.05) effect on the body weight. The least-squares means of semen volume (ml/ejaculate), sperm concentration (109 /ml), mass motility (%), live spermatozoa (%) and normal spermatozoa (%) were 0.5, 2.4, 80.0, 86.5 and 89.3, respectively. Age of bucks had significant (p<0.01) affect on semen volume, sperm concentration. Body weight had a significant (p<0.05) effect on semen volume only. Least-squares mean of daily milk yield was 379.9 lit.. Milk yields was significantly (p<0.01) affected by litter size and season of kidding. It is suggested that nongenetic factors should be adopted as a technique for improving the productive traits

Esterase variability in different tissues of Naked Neck Fowl (Gallus gallus domesticus) of Bangladesh using polyacrylamide gel electrophoresis

Naked neck fowl (Gallus gallus domesticus) comprises one of the indigenous chicken populations in Bangladesh. The present investigation was conducted to study the polymorphic pattern of the estrase isozyme in different tissues of the fowl by polyacrylamide gel electrophoresis (PAGE) system. In this experiment, α-napthyle and β-napthyle acetate were used as substrate. Esterase variability of different samples of fore brain, mid brain, hind brain, heart brain, liver, testis, oesophagus, gizzard, bile ducts, proventiculus, small intestine, large intestine pectoral muscle, pelvic muscle, lung, eye, kidney, pancreas, body muscle and blood cells were examined. Altogether four esterase bands were observed and the bands were designated as Esterase Est-1 2.0, Est-21.0 Est-30.75 and Est-4o.15. Among the four bands Est-1 was the fastest and placed near to anode (+) electrode. Esterase showed tissue specific variation. Est-2 was found in almost all tissues, whereas Est-1 was observed only in liver. Est-3 and Est-4 were expressed exclusively in the nervous system especially in brain. Such findings may provide basic information to analyze the esterase activity in different tissues

Characterization of Black Bengal goat

Characterization of Black Bengal bucks and does was performed in this study. A total of 50 goats of different aged were studied. The experiment was performed in Black Bengal bucks and does at 1st day and at 3, 6, 9 and 12 months of age for measuring different parameters such as body length, heart girth, wither height, hip height, fore and hind leg length, head length and width, head length and width, ear length and ear breath, scrotal length and scrotal circumference. In a single parameter as body weight of Black Bengal bucks and does at 1st day and at 3, 6, 9 and 12 months of age were found to be 1.08±0.06, 5.22±0.33, 8.95±0.34, 12.05±0.47 and 14.20±0.20; and 1.01±0.23, 3.93±0.19, 7.41±0.27, 9.53±0.38 and 12.40±0.41 kg respectively. Whereas all the finding where gradually increased for all parameters according to their specific age periods. Body weight has a strong positive relationship with heart girth, body length, height at wither, scrotal length and scrotal circumference in Black Bengal goat. All the parameters studied found comparatively higher in bucks than does

A baseline survey on the availability of Black Bengal breeding bucks in different districts of Bangladesh

The present study was conducted to assess the availability of Black Bengal breeding bucks in five districts from the Northern part (Lalmonirhat and Rangpur), Central part (Tangail and Mymensingh) and Southern part (Khulna) of Bangladesh and also to explore the relationship between distance of does from these breeding bucks and type of scarcity. The data were collected using a pre-tested questionnaire from 100 goat rearers of 100 villages in five districts. In this study, the selected characteristics of the respondents and other factors on the availability of Black Bengal breeding bucks were considered as independent variable whereas type of scarcity was considered as dependent variable. The buck and doe ratios were 1:164, 1:138, 1:114, 1:127 and 1:96 in Lalmonirhat, Rangpur, Tangail, Khulna and Mymensingh district, respectively. The pooled buck and doe ratio was 1:128. More than 70% farmers faced severe shortage of breeding bucks for serving their does in the above districts which ultimately represent the overall situation of the country. Almost all farmers (100%) had to depend on natural mating to serve their does except the farmers of Mymensingh where 12% farmers depended on artificial insemination in goat. It was observed that type of scarcity had significantly positively correlated (0.933) with distance of does from breeding bucks. This also indicated that type of scarcity gradually reached to severe level which may create the inbreeding depression in goat breeding
