Title: NOVEL MULTINUTRIENT CATTLE BISCUIT AS AN ALTERNATIVE TO TRADITIONAL UREA SUPPLEMENTS FOR DAIRY COW
Authors: Sultan, Md. Nahid
Abstract: The study was carried out in a selected commercial dairy farm of Patiya under Chittagong
Division, Bangladesh for a period of 60 days from September to October 2014 to innovate
novel cattle biscuit as an alternative to traditional urea supplements for dairy cow. Twenty
Local × Holstein crossbred milking cows were selected according to age, live weight, BCS
and daily milk yield from the experimental farm. Animals were randomly distributed into
five dietary treatment groups designated as T0, T1, T2, T3 and T4 having four replicates per
treatment. All animals were stall fed. Ration was prepared and supplied to the animal as per
recommendation. Multi-nutrient Cattle Biscuit (MCB) was fed twice daily. All animals had
free access to clean, cool drinking water. Intake of basal diet was recorded daily. All animals
were kept in a single row stanchion barn. Body weight was measured, milk yield was
recorded, milk and blood parameters were tested in the laboratory.
The daily milk yield of the cows in the experimental groups supplemented with varied levels
of MCB significantly (p<0.05) increased for the last four weeks. The highest average milk
yield (8.3 kg/d) was recorded in T3 group and the lowest milk yield (6.3 kg/d) was recorded
in T0 group. Milk composition of the cows varied in an irregular fashion during the
experimental period. Fat percent of milk significantly (p<0.05) increased during 1st, 2nd, 3rd,
7th and 8th week in the treatment groups compared to control group. Besides fat, protein
percent of milk increased significantly in the 1st (p<0.001); 2nd, 5th, 8th (p<0.05) and 7th
(p<0.01) week. The Solids not fat (SNF) percent differed significantly in the 1st, 2nd, 5th
(p<0.01); 3rd and 7th (p<0.001) week. Unlike SNF, the total solids (TS) percent differed
significantly in the 1st, 7th (p<0.01); 3rd (p<0.001) and 5th (p<0.05) week. On average (1-8
weeks), milk fat, milk protein, SNF and TS percent were higher in the T2 (25% urea
supplemented MCB) and lower in T0 (without MCB) group respectively.
Unlike milk components, there was no significant difference (p>0.05) in serum cholesterol,
serum glutamic pyruvic transaminase (SGPT), bilirubin, urea and total protein level
throughout the whole experimental period. However, serum glutamic oxaloacetic
transaminase (SGOT) differed significantly (p<0.05) only in the 5th week. Creatinine differed
significantly in the 2nd (p<0.01) and 3rd (p<0.05) week. Glucose level differed significantly in
the 1st (p<0.01), 5th (p<0.001) and 8th (p<0.01) week. In the light of above observations, it
might be concluded that, MCB supplementation substantially improved milk yield and milk
composition and did not interfere blood parameters of the experimental cows. Therefore,
25% urea supplemented MCB in addition to basal diet may be suggested as a novel
alternative to traditional urea supplements for dairy cow.2014-12-01T00:00:00ZPREPARATION OF LEAST COST DOG BISCUIT BY USING AVAILABLE FEED INGREDIENTS

Title: PREPARATION OF LEAST COST DOG BISCUIT BY USING AVAILABLE FEED INGREDIENTS
Authors: AHMED, MD. IMRAN
Abstract: The current research work was undertaken for a period of six months to screen out the available feed resources at CMP (Chittagong Metropoliton) areas usable for dog biscuit. The two areas found suitable for this purpose viz. Jhawtola bazaar and CVASU on the basis of their availability. Four different types of samples were chicken intestine, chicken intestine with skin, fish scale and dead chicken carcass collected from the study areas. Chemical analyses of the samples were carried out in for dry matter (DM), crude protein (CP), crude fiber (CF), nitrogen free extracts (NFE), ether extracts (EE) and total ash in the animal nutrition laboratory at Chittagong Veterinary and Animal Sciences University, Chittagong, Bangladesh. Results indicated that, all samples had substantial amount of proximate components that might have been used as alternative feed resource in dog food. Among them the dead chicken meal found to be better for the preparation of dog biscuit as compared to the chicken intestine or fish scale. The another trial was conducted to test the prepared dog biscuit with the objectives of formulating a least cost palatable dog biscuit using locally available ingredients in Bangladesh, which confirm the main nutritional requirements and to determine its influence on growth rate of local breeds. A total of 18 puppies (between 08-12 weeks of age) were used in this study. Feed offered, body weight gain, metabolic profile test, serum electrolyte concentrations and hematological analysis were done on weekly basis to determine nutritional status. It was found that the body weight gain and feed intake had a significant (P<0.05) and positive relationship. It was found that the weight gain of puppies which were fed using homemade food was 1.62 ± 0.04 kg whereas 2.02 ± 0.27 kg and 2.11± 0.13 kg was the weight gain of puppies which were fed using commercial food and prepared biscuits, respectively. Result of metabolic profile test, serum electrolyte concentration, hematological analysis and digestibility revealed no significance difference between groups those were fed commercial food and prepared biscuits and cost comparison reveal prepared biscuit was too economic than the commercial food. In conclusion, both commercial food and prepared biscuits showed similar result in terms of weight gain, metabolic profile test, serum electrolyte concentration, hematological analysis and digestibility.2015-06-01T00:00:00ZEFFECT OF TWO DIFFERENT COMMERCIAL EMULSIFIERS ON GROWTH PERFORMANCE OF BROILERS

Title: EFFECT OF TWO DIFFERENT COMMERCIAL EMULSIFIERS ON GROWTH PERFORMANCE OF BROILERS
Authors: Roy, Popi
Abstract: A study was conducted to evaluate the effect of two exogenous (commercial) emulsifiers in energy based diet on broiler performance. A total of 90 day-old chicks (Cobb-500) were randomly distributed to the three treatment groups; each with three replicates. The experimental diet To (Basal diet as control), T1 (Basal diet+ 0.06% lysolecithin in both starter & grower ration) and T2 (Basal diet+0.08% glyceryl polyethylene glycol ricinoleate in both starter & grower ration) were fed to the respective groups for 28 days. Body weight, body weight gain and feed intake were taken weekly interval. It was observed that body weight was significantly (P<0.05) increased in both lysolecithin and glyceryl polyethylene glycol ricinoleate (GPEGR) supplemented diet group comparing to the control group at 4th week of age. Highest body weight was observed in GPEGR supplemented diet group and lowest in control group. Body weight gain was not significantly (P>0.05) affected but cumulative body weight gain was increased significantly (P<0.05) in both lysolecithin and glyceryl polyethylene glycol ricinoleate (GPEGR) supplemented group. Feed intake at 1st, 2nd, 3rd weeks varied significantly (P<0.05) differed except at 4th week, where it was statistically similar in diet groups. Feed conversion was significantly (P<0.05) improved along the whole study period in broilers fed diet containing lysolecithin and GPEGR comparing to control group. In cost items, significant (P<0.05) differences were observed in total cost (Tk/broiler) and total cost (Tk/Kg live broiler). Total cost (Tk/Kg live broiler) was highest in control group and lowest in GPEGR group. In term of income, total sale price (Tk/broiler), net profit (Tk/broiler), net profit (Tk/Kg live broiler) was increased significantly (P<0.05) in GPEGR and lysolecithin supplemented diet group than control group. The study revealed that supplementation of exogenous emulsifiers in diets improves broiler performance.2014-12-01T00:00:00ZTRANSPORTATION STRESS ON CATTLE IN BANGLADESH: ITS EFFECTS ON PHYSICAL, BIOCHEMICAL AND HORMONAL CHANGES, AND IMMUNE RESPONSE

Title: TRANSPORTATION STRESS ON CATTLE IN BANGLADESH: ITS EFFECTS ON PHYSICAL, BIOCHEMICAL AND HORMONAL CHANGES, AND IMMUNE RESPONSE
Abstract: A cross-sectional study was conducted during the period of July- December, 2014 to determine the effect of transportation stress of cattle used for beef purpose in Bangladesh. A total of 100 cattle were randomly selected, those were subjected to long distance transportation (648km, 14h). A pre-structured record sheet was used to record the injury related data, physical parameters and others relevant data both before and after transportation. Blood samples were collected from 50 selected cattle for three times (before, after and 24h of post transportation) from each. Routine examinations of blood were done by standard procedure. The biochemical and cortisol hormone analysis were performed by using biochemical analyzer and ELISA based commercial kit, respectively from serum. The frequencies of injuries were increased significantly (P<0.01) after transportation (47%) than before (26%). The injuries were most common in Hariana cattle both before (5%) and after (8%) transport. Abrasion was dominated type of injury (11%) and were increased significantly (P<0.05) after transportation. The most frequent location of injuries was pin bone in both phase of the study. The frequencies of nasal discharge and degree of dehydrations were significantly (P<0.01) increased after transportation. Among the hematological parameters the hemoglobin (Hb), total erythrocyte count (TEC), total leukocyte count (TLC) and neutrophils count were increased significantly (P<0.05) after transportation while the lymphocytes count were decreased significantly (P<0.01). Among the biochemical parameters the serum total protein (TP), calcium (Ca), phosphorus (P), creatine kinage (CK) and triglyceride (TG) level were increased significantly (P<0.01) after transportation, while serum alkaline phosphatase (ALP) level was decreased. The serum cortisol hormone revealed no significant variation (P>0.05) before and after transportation. Immune responses of the transported cattle were expressed by increased (P<0.01) neutrophil count, decreased (P<0.01) lymphocyte count and increased (P<0.01) neutrophils and lymphocytes ratio after transportation (0.56±0.01) than before (0.48±0.01). Increased number of injuries, enormous changes of hemato-biochemical parameters during transportation indicates relatively higher degree of stress and suffering. Cattle trader should aware about the comfortless of animal during transportation for maximum productivity as well as to maintain animal welfare.2014-12-01T00:00:00Z
