Three ewes were used in 3×3 Latin square design over three periods with three dietary treatments as hay diet, low ethanol APS (L-APS, ethanol 48.7 g kg<sup>-1</sup> DM) diet and high ethanol APS (H-APS, ethanol 87.2 g kg<sup>-1</sup> DM) diet. Alfalfa hay cube and APS provided half of 110% TDN requirement for APS diets. The area upper or under the curve (AUC) of plasma ethanol was greater (P&lt;0.01) in APS diets than that of hay diet and H-APS diet had grater (P&lt;0.01) AUC than that of L-APS. The AUC of plasma β-hydroxybutyrate in both APS diets were greater (P&lt;0.01) than that of hay diet. Plasma ethanol AUC was positively correlated (P&lt;0.05) with the AUCs of plasma lactate, triglyceride and glutamate oxaloacetate transaminase (GOT), and negatively correlated (P&lt;0.05) with the AUC of plasma urea nitrogen. Plasma lactate AUC was positively correlated (P&lt;0.05, P&lt;0.01, and P&lt;0.05, respectively) with the AUC of free cholesterol, triglyceride and GOT, and negatively correlated (P&lt;0.01) with that of plasma urea nitrogen. The AUC of plasma β-hydroxybutyrate was negatively correlated (P&lt;0.01) with that of glucose. Finally, blood parameters examination revealed that feeding of APS lead to increase plasma ethanol, lactate, β-hydroxybutyrate and lipid components and tended to decrease glucose levels.</p> <p><em>Bang.

Semen parameters were evaluated from 30 ejaculates from each bull and fertility rate was calculated based on 60-days non-return rate via AI using these semen samples. Genetic group of breeding bulls had significant (p&lt;0.05) effect on <em>libido</em>. Holstein Friesian cross breeding bulls showed significantly (p&lt;0.05) highest <em>libido </em>(3.77±0.15) followed by Brahman cross (3.38±0.07) and lowest in Red Chittagong (RC) breeding bulls (2.96±0.11). Semen attributes also significantly affected by the different genetic group of bulls. Holstein Friesian crossbred breeding bulls with highest <em>libido</em> provided significantly (p&lt;0.01) highest volume of semen (5.63±0.16 ml) per ejaculate, progressive motility (74.73±0.76%), live sperm (84.18±0.62%) and normal sperm (83.18±1.47%) whereas these parameters were significantly (p&lt;0.01) lowest in RC breeding bulls. Moreover, <em>libido</em> showed a strong and positive correlation with all these semen parameters. The fertility rate was also significantly highest (p&lt;0.05) in Holstein Friesian crossbred breeding bull (63.67±1.46%), followed by Brahman crossbred (58.86±1.05%) and lowest in RC breeding bulls (53.42±0.85%). These results suggested that semen quality is positively correlated with the <em>libido</em> of breeding bulls and quality is important for higher fertility. Therefore, <em>libido</em> as well as semen quality evaluation may be important criteria to discard the breeding bulls with poor fertility in an AI program.</p> <p><em>Bang. J. Anim.

Two hundred and ten birds of average weight of 167.75±3.94g were used for this study, and they were allocated randomly into seven treatment groups and replicated thrice. Group 1 served as control without inclusion of LAYPLUS<strong><em>®</em></strong>, while groups 2, 3, 4 and 5 had 250 mg/kg, 500 mg/kg, 750mg/kg and 1000mg/kg inclusion of LP and group 6 had 240mg/kg of vitamin E, respectively, and group 7 clomiphene citrate. Eggs were collected daily and egg production was calculated on a bird-day basis. The data obtained were analyzed using one-way ANOVA. There was significant increase (p&lt;0.05) in the egg production parameters namely egg weight, egg laid per hen and percentage laying rate of LP500mg/kg compared with other groups. The highest percentage egg production was by the LP500mg/kg at 57% while the lowest was by the LP250mg/kg at 41%. There was no significant difference in the egg weight and Haugh unit among the supplemented birds and the control group. There was significant difference among the treatments in the percentage hatchability of the eggs with LP500mg/kg eggs recording the highest value of 95.68%. It can be concluded from this experiment that supplementation of the feed with LP at 500mg/kg had beneficial effect on quail production through improved effect on egg production and hatchability.</p> <p><em>Bang.

During first 4 weeks, all chicks were kept together, whereas chicks of ND was brooded in the same room but separated by a partition. At 5 weeks of age chicks were randomly distributed to the selected farmers. Growth parameters were recorded to determine the comparative growth performance among four genotypes of chicken. The highest body weight (1110.76 g/bird) was achieved by HC, followed by IN (900.63 g/bird) and NN (831.13 g/bird) at 12 weeks of age. The lowest body weight (734.13 g/bird) however was found in ND chicken. During the growing period under free range rearing (5-12 weeks), HC group consumed the highest amount of feed (2697.02 g/bird) with an average FCR of 3.06 while the lowest feed consumption (2666.13 g/bird) with the highest FCR of 4.90 was observed in ND. IN consumed (2674.63 g/bird) feed with an average FCR of 3.92 and BLRI improved NN consumed (2668.13 g/bird) feed with an average FCR of 4.19. Live weight gains in all the four genotypes of indigenous chicken were changed almost in a similar pattern. Significant differences were observed in live weight, dressing percentage, breast meat, drumstick, thigh meat among the four genotypes of chicken. The HC was superior to other genotypes of indigenous chicken including ND in terms of growth performance, meat yield characteristics and net returns.</p> <p><strong><em>Bang. J. Anim.

The study was carried out for 36 days at Avian Research Unit,&nbsp;Regional Agriculture Research Station, Parwanipur, Bara, Nepal. Concentrate mixture and lemongrass oil were procured from Shakti Feed Industry, Birgung; Herbs Processing Plant of Ministry of Forest and Soil Conservation, Jadibuti, Kathmandu, respectively. Experimental birds were provided <em>ad libitum </em>amount of starter feed from 0 to 21 days and finisher feed from 22 to 36 days. Feed intake was recorded daily and body weight gain was measured in 7 days interval. The study revealed that the cumulative feed intake per bird was found higher in T<sub>3</sub> (3443.17g) followed by T<sub>4 </sub>(3377.33g) and T<sub>2 </sub>(3354.04g), respectively, and were statistically non-significant among the diet groups. The FCR was highest in T<sub>3</sub> (1:1.44 kg) and lowest in T<sub>4</sub> (1:1.51 kg), and differed insignificantly among the diet groups. Similarly, the total weight gain of the experimental bird was found to be higher in T<sub>3</sub> (2385.13g) followed by T<sub>1 </sub>(2279.46g) and T<sub>2 </sub>(2271.86g), respectively.&nbsp; The average daily gain of experimental birds noted higher in T<sub>3</sub> (66.25g) followed by T<sub>1</sub> and T<sub>2</sub> (63.31g) and (63.1g), respectively.&nbsp;The experiment suggested that inclusion of lemongrass oil could be considered as an alternative to antibiotic growth promoter in broiler diet to enhance the production performance.</p> <p><em>Bang.

Reconstituted milk was prepared by using the instructions given on the packet of whole milk powder. The prepared reconstituted milk was divided into three parts and three different types of puddings were prepared by using 2 eggs, 3 eggs and 4 eggs with reconstituted milk. Amount of milk, sugar and corn flour level was same in all three types. The puddings were designated as A (2 eggs), B (3 eggs) and C (4 eggs) types. Prepared pudding samples were subjected to physical and chemical analysis to monitor their quality. Physical properties (smell, color, consistency and texture) showed pudding that contained 3 eggs obtained the best score (89.13±3.77) from the judges. From chemical analysis, it was observed that 4 eggs containing pudding showed the highest nutritive value as compared to control and other group but organoleptic score was highest for 3 eggs containing pudding.</p> <p><em>Bang.

A total of 12 lactating Jersey dairy cows, apparently having similar reproductive and productive performances were selected. The cows were randomly grouped into 3 treatments groups; T1 (Control): 6 kg concentrate mixture, T2: 6 kg concentrate mixture plus 1.5 kg heat-treated soybean cake, and T3: 6 kg concentrate mixture plus 1.5 kg formalin treated soybean cake. An acclimatization period of 7 days, the experimental procedure was carried for the period of 62 days. Other management; feeding - adlib amount of straw and green grass such as oat, signal and local grass once a day, natural grazing average 3 hrs/ day), watering and housing remained as routinely done by the farm. The compound feed was procured from Fine Feeds Industries Pvt. Ltd., Chitwan, Nepal. Feed intake and milk production of&nbsp;individual&nbsp;animal was recorded daily. The straw and concentrate intake of experimental cows among the treatment groups differed significantly (P&lt;0.001), whereas green grass intake among the diet groups differed insignificantly. The initial recorded milk production 5.4 L, 5.45 L and 5.62 L among the treatment groups found insignificant, whereas the final milk production 7.85 L, 6.12 L and 5.82 L among the treatment groups found highly significant (P&lt;0.001). The economic analysis (its cost benefits per L of milk production) during the period of 62 days of experimentation, it was revealed that feeding package T2 is more beneficial than T3. The net income accounted for NRs 12152.11 and NRs 7457. 55 using T2 and T3 feeding package, respectively. Therefore, it is suggested that heat-treated soybean cake supplementation to early lactating (up to 3 months) dairy cows is one of the option to increase milk production and income of farmers. Further study needed to be carried out to ascertain the optimum level and duration of additional protein supplementation to dairy cows.</p> <p><em>Bang. J. Anim.

Ground beef samples were divided into four treatment groups having bottle gourd leaf extracts as control T<sub>1</sub> (0%), T<sub>2</sub> (1%), T<sub>3 (</sub>2%), T<sub>4</sub> (3%). Proximate analysis, sensory tests (color, flavor, tenderness, juiciness, and overall acceptability), cooking loss, pH value, free fatty acids (FFA), thiobarbituric acid values (TBARS), peroxide value (POV) and microbiological examination were determined. Days of intervals of experiment were 0, 15<sup>th</sup>, 30<sup>th</sup> and 45<sup>th</sup> days. Data were analyzed using SAS Statistical software. DM content of all the treatment groups differ significantly (p&lt;0.05). In contrast, DM content increased significantly (p&lt;0.05) with the advancement of different days of intervals. The CP and EE content at different treatment levels differ significantly (p&lt;0.05). The FFA, TBARs, POV values were decreased significantly (p&lt;0.05). The color, flavor, tenderness, juiciness, overall acceptability, raw and cooked pH were increased at different treatment levels significantly (p&lt;0.05). The cooking loss (%) with the advancement of days of intervals were differ significantly (p&lt;0.05). TCC (<em>log </em>CFU/g) and TYMC (<em>log </em>CFU/g) were decreased significantly (p&lt;0.05) at different treatment levels. Parameters studied showed that, 2% bottle gourd leaf extract added meat balls were the best quality, so it may be concluded that&nbsp; 2% bottle gourd leaf extract can be used in beef meatball as a source of antioxidant and antimicrobial agent to increase shelf-life of meatballs.</p> <p><em>Bang.
