  • Four ruminally cannulated buffalo bulls were fed mottgrass diets using a $4{\times}4$ Latin square design. Treatments were arranged factorially and consisted of mottgrass fertilized with 0 for Kg nitrogen (N) per acre and harvested at 40 and 60 days of age. Nitrogen fertilization improved the concentrations of neutral detergent fiber (NDF), and acid detergent fiber (ADF) in early-cut mottgrass (ECM) but, the acid detergent lignin (ADL) contents were higher in the late-cut mottgrass (LCM). The crude protein (CP) contents of the mottgrass decreased with advancing maturity, but N fertilization increased CP at both maturities. The intake of dry matter (DM), organic matter (OM), CP, NDF and ADF were higher by buffalo bulls fed ECM than those fed LCM. The ruminal pH increased in first 6 hours post feeding in animals fed N fertilized mottgrass and may be due to higher concentration of ruminal ammonia. The digestibilities of DM, OM, CP, NDF and ADF were higher by buffalo bulls fed ECM than those fed LCM. However, the application of N fertilizer did not affect the digestibilities of these nutrients.

  • In situ and in vivo digestion trials were conducted to determine the degradation of dry matter (DM), crude protein (CP) and effective protein degtadability (EPD), and digestibility of nutrients of Hazelnut kernel oil meal (HKOM), and effects of HKOM on nitrogen (N) balance. In the in situ study, nylon bag were suspended in the rumen of 3 Karayaka rams to estimate protected protein. Protein sources were analyzed for pepsin soluble protein (PSP) using a Pepsin Digestion Method. In the digestion trials, 4 Karayaka rams (36 mo.) were used in a $4{\times}4$ Latin square to evaluate the digestibility of nutrients and N retention to measure effects of diets containing HKOM, soybean meal (SBM) corn gluten meal (CGM) and urea (U). The degradability of DM and CP, and PSP content of HKOM were lower (p>0.05) than that of SBM, but higher (p<0.001) than that of CGM. EPD of HKOM was higher (p<0.01) than that of SBM or CGM. The apparent digestion coefficients of organic matter and CP for HKOM were lower than for SBM, but higher than for CGM. N retention of HKOM was higher than that of SBM and lower than that of CGM (p>0.05). In conclusion, these data may indicate that the HKOM is a high digestible feed source with a value between SBM and CGM.

  • An experiment was conducted for 56 days using nine castrated male Black Bengal goats (initial live weight 9.0 kg) aged about 5 months to study the effects of feeding Sesbania leaves as a sole feed on growth performance and nutrient utilization. The animals were fed ad libitum on either road-side grass, Sesbania aculeata leaves or Sesbania rostrata leaves. Average dry matter (DM) intake was 179, 229 and 259 g/d for goats fed road-side grass, Sesbania aculeata and Sesbania rostrata, respectively. Corresponding mean values for average daily live weight change were -6.6, 9.5 and 38.1 g, respectively. These values were higher (p<0.05) for goats fed Sesbania leaves than those given road-side grass. The apparent digestibility of all the proximate components except CF and the concentrations of DCP, TDN, DOM and ME of Sesbania leaves were higher (p<0.05) than those of road-side grass. Sesbania rostrata was superior (p<0.05) to Sesbania aculeata for nutrient digestibilities (except for NFE) and also for DOM, DCP and ME concentrations. Therefore, it may be concluded that the production of Sesbania rostrata, a legume fodder, should be encouraged for feeding goats.

  • Twelve indigenous(desi) growing male calves of 9-12 months of age($95.3{\pm}12.6kg$) were divided into 4 groups having 3 animals in each group. Each group of calves received 1 kg fresh concentrate mixtures where tea waste was supplemented as 0($T_0$), 50($T_1$), 100($T_2$) and 150($T_3$) g $d^{-1}$ with the replacement of equal amount of concentrate mixtures. In addition, each calf received ad libitum chopped rice straw and 2 kg green grass a day. Dry matter intake increased by offering higher levels of tea waste except in the treatment $T_3$. Daily gain(g $d^{-1}$) was comparatively higher in $T_2$ group(314.6g) compared to other treatments. Feed efficiency(kg DM $kg^{-1}$ gain) was also higher in $T_2$ group(9.9) where feed cost $kg^{-1}$ gain was also comparatively lower(Tk. 25.7) than the other treatments. Dry matter and CP digestibility increased with the increase in supplementation of tea wastes except in the treatment $T_3$.

  • In many countries, goat milk is an excellent nutrient source and is less allergenic for children and the elderly. The casein composition of goat milk consists largely of ${\beta}$-casein and lower amounts of ${\alpha}_{s1}$-casein, which may interfere with digestion by forming solid curds in the human stomach. Goat milk contains small fat globules and large amounts of medium chain fatty acids for, better digestibility, as well as abundant minerals and vitamins with high absorption rates. Recently, the medical benefits of goat milk in different human disorders have been recognized, leading to an increased interest in developing functional foods with goat milk, particularly for individuals with malabsorption syndrome. However, the physiological and biochemical properties of goat milk are largely unknown. We review the importance of goat milk as a potential functional food by providing scientific evidence confirming its health benefits.

  • Twenty lactating crossbred cows yielding 10 to 15 litres of milk daily during mid lactation were selected and divided into four groups of five animals to assess the effect of feeding calcium soaps of palm oil fatty acids (bypass fat) on milk yield, milk composition and nutrient utilization in lactating crossbred cows. The animals in groups 1 (control), 2, 3 and 4 were fed concentrate mixture containing 0 (no bypass fat), 2, 4 and 6% bypass fat, respectively. The average daily dry matter consumption in the various groups ranged from 13.1 to 13.6 kg and showed no significant difference among treatment groups. There was no significant difference among different groups in digestibility of DM, OM, CP and CF, however, ether extract digestibility in cows of groups 2 and 4 was significantly (p<0.05) higher than the control group. The average milk yields of the cows in group 3 (4% bypass fat) showed a significantly (p<0.05) higher value than cows of groups 1 and 2. Similarly, a significant (p<0.05) increase in fat yield, 4% FCM yield and SNF yield was observed for the cows in group 3 (4% bypass fat). The milk composition in terms of total solids, fat, lactose, protein, solids-not-fat and ash percentage showed a varying response and bypass fat feeding did not have any effect on milk composition of cows in different groups. The gross and net energetic efficiency of milk production ranged from 23.6 to 27.5% and 37.1 to 44.4%, respectively, and showed no significant difference among different treatment groups. The gross and net efficiency of nitrogen utilization for milk production ranged from 24.0 to 28.7% and 37.2 to 43.5%, respectively, and no significant difference was noted among different treatment groups. The supplementation with calcium salts of palm oil fatty acid reduced the proportion of caproic, caprylic and capric acids and significantly (p<0.01) increased the concentration of palmitic, oleic, stearic, linoleic and linolenic acids in milk fat with increase in level of bypass fat supplementation. It was concluded that incorporation of calcium salts of palm oil fatty acids at a 4% level in the concentrate mixture of lactating crossbred cows improved the milk production and milk quality in terms of polyunsaturated fatty acids without affecting the digestibility of nutrients.
