After two months of ensiling, the silage was evaluated and used in the ration of lactating buffaloes. A Latin square experiment in a changeover design, with three periods of time, each with 20 days for adaptation and 10 days for recording data, was conducted in which 15 multiparous lactating buffloes were used in three similar groups, each with five animals. The prepared silage was included in the diet of lactating buffaloes where a control diet （A） was compared with treatment diets contained 25% （B） and 50% （C） silage （DM basis） respectively. Milk yield was recorded, sampled and analysed for fat, protein, solid not-fat and total solids-content. The maximum daily rough milk yield per animal was obtained on diet C while minimum on diet A （P 〈 0.05）. Similar trends were observed for 4% fat corrected milk, and 3.5% fat corrected milk that were significantly different between the treatments （P 〈 0.05）. The percentage of crude fat and daily fat yield per animal were significantly （P 〈 0.05） higher in treatment C comparing to A and B. An increasingly trend of milk and fat yield was observed when the animals received silage contained diets but statistically it was significant only for the diets contained 50% silage. In addition, the fat percentage was significantly （P 〈 0.05） increased when the buffaloes received diet containing 50% silage. The highest （P 〈 0.05） amount of protein and total solid yield obtained, when the animals received high （50%） silage diet.展开更多

For this purpose, a total of 195-day old broiler chicks （Arbor acres） were randomly allocated into five treatments groups with 39 chicks and three replicates of 13 chicks in each. Blended grains of selim was given through drinking water on treatments T2, T3, T4 and T5 at concentrations of 0.4, 0.6, 0.8 and 1,0 g/L, while chicks on treatment T1 （control） received antibiotics （Doxy-gen 20/20 WSP： Doxycycline hyclate 200 mg and Gentamicine sulfate 200 mg） at 0.3 g/L of water. All the experimental chicks were fed ad libitum with diet containing 23% crude protein and 2,851.55 kcal/kg metabolizable energy for 28 d. The results revealed that there were similarities （P 〉 0.05） in final body weight, total weight gain, daily weight gain, total feed intake, daily feed intake and feed conversion ratio among the treatments. There were significant （P 〈 0.05） differences in the microbial count of faeces before the birds received antibiotics and grains of selim, but count were similar （P 〉 0.05） after grains of selim and antibiotics were administered. Cost of total feed consumed, cost of per kg feed and cost of per kg weight were significantly （P 〈 0.05） higher in treatment T1, but cost differential and relative cost benefit were similar （P 〉 0.05）. Results indicate that grains of selim have antimicrobial and anthelminthic properties, and promote growth in broiler chickens.展开更多
