죽염은 우리나라에서 전래되어온 전통적 민간 의방의 하나로서 소화기 장애의 치료제로 사용되었다. 또한 염증, 당뇨, 순환기 질환, 바이러스성 질환 및 암 등 여러 가지 병의 치료에 효과적이라고 알려져 있다. 죽염은 여러 가지 광물질을 함유하고 있어 가축의 사육과정에서 생산성 향상에 영향을 미칠 것으로 사료된다. 따라서 본 시험은 3회 구운 생활죽염을 사료에 첨가 급여할 때 육계의 생산성에 미치는 영향을 규명하기 위하여 기초사료에 죽염을 0.1%, 0.2% 및 0.3% 수준으로 첨가 급여하여 육계의 증체량, 사료섭취량, 사료요구율, 도체성분 및 혈액 성분에 미치는 영향을 분석하고자 사양시험을 실시하였으며, 본 시험에서 얻어진 결과를 요약하면 다음과 같다. 육성전기에 생활죽염 첨가에 의한 증체량의 차이가 나타났으며 0.3% 첨가구인 T3구가 대조구에 비하여 9.6% 향상된 증체성적을 보였다. 사료요구율은 대조구에 비하여 죽염 0.3% 첨가구인 T3 처리구가 유의적으로 낮게 나타나, 약 2.6% 향상된 결과를 보였다(p<0.05). 또한 음수량과 분변 중 수분함량은 0.3% 죽염을 첨가 급여할 경우, 대조구에 비해 유의적(p<0.05)으로 증가하였으나, 닭가슴살의 일반성분, 복부지방함량 비율 및 혈액 성분은 죽염 첨가에 의한 유의적인 차이를 보이지 않았다. This study investigated the effect of bamboo salt (BS) on body gain, feed intake, meat composition, and blood characteristics of broiler chicks. BS was processed by roasting salt at 1,200∼1,300℃ in a bamboo container, with the open end plugged with red clay. In total, 120 broiler chicks were assigned to four treatments. Each treatment was triplicated, with 10 chicks in each treatment group. The supplementation levels of the three BS-treated feeds were 0.1, 0.2, and 0.3%. Body weight gain slightly increased in broiler chicks fed diets supplemented with BS compared to that of the control during the overall test period. However, no significant differences were observed among treatments. Feed intake was also not significantly different among treatments. Feed efficiency was significantly (p<0.05) improved in broiler chicks fed diets supplemented with BS compared to that of the control. Body weight gain was more positively affected by the dietary BS supplement at the beginning of the experimental period than toward the end. Water intake was positively correlated with the dietary 0.3% BS level (p<0.05). Breast meat composition and cholesterol levels were also not affected by BS supplementation. The total protein, albumin, glutamic oxaloacetic transaminase (GOT), glutamic-pyruvic transaminase (GPT), and total cholesterol levels in the blood were not significantly different among treatments.

This study was carried out to determine the effect of dietary Aspergillus oryzae yeast culture(YC) which was incubated in wheat flour medium on body weight gain, feed intake and feed efficiency in broiler chicks. Forty broiler chicks were assigned to each of 6 treatments with 4 replications. The supplementation levels of YC in the experimental diets were 0, 0.1, 0.3, 0.5, 0.7 and 1.0%. The body weight gain (BWG) of chicks fed the dietary YC slightly increased compared with those of the control. The treatment with 1.0% YC produced the highest BWG. But the significant differences (P$lt; .05) among the treatments were not found statistically. Average feed intake were not significantly different among the treatments. Average feed efficiency of the chicks fed YC was significantly(P$lt;.01) improved compare to that of the control. The most efficient result was found in the chicks of 1.0% YC.

Effect of environmental temperature and defeathering (DF) on the energy metabolism of cockerels was examined and results obtained are as following. 1. Environmental temperature (ET) affected heat production (HP) during feeding condition. Under 25℃ ET, HP per ㎏ metabolic body weight (MEW) were decreased with increasing ET, which is showing 146.4, 131.5, 115.9 and 88.8 Kcal under S, 15, 25 and 35℃ ET, respectively. 2. Mean HP per ㎏ MEW were respectively 120.6, 131.2 and 188.0 Kcal for 0, 50 and 100% DF treatment which is revealing the increasing HP with increasing DF level. 3. Metabolizable energy requirement for maintenance (MEm), which were 143.3, 120.6, 111.0 and 86.7 Kcal/MBW with respective ET of 5, 15, 25 and 35℃, were decreased with increasing ET. There were increased in MEm with increasing DF level under 25oC. There were 115.4, 126.6 and 192.1 Kcal for cockerels with DF level of 0, 50 and 100, respectively. However, no such difference was observed under 35℃ ET. 4. No effect of ET on Net availability of metabolizable energy (NAME) was observed. However, in average, the marginal decrease of NAME which were 66.6, 64.5 and 57.6% was shown with increasing level of DF, which respectively were 0, 50 and 100%. Effect of DF level was not observed exceptic ally under 35℃ ET.

Effect of environmental temperature and defeathering (DF) on the fasting heat production (FHP) in white Hisex cockerels was examined at 5, 15, 25 and 35℃ of temperature and 0, 50 and 100% defeathering conditions. Series of experiment were carried out with three open-circuit respiration chamber. The results can be summarized as follows: 1. FHP had negative correlation with the environmental temperature (ET), therefore, FHP of cockerels decreased continually with increasing ET. The relationships between FHP (Y) and ET (X) expressed as a linear regression equation were: Control treatment (0% DF); Y=-1,167X + 100.41 (r=0.9779), 50% DF treatment; Y=-1.429X + 109.90 (r=0.9968), 100% DF treatment; Y=-2.887X + 165.31 (r=9717). 2. FHP of the cockerels was also increased (p$lt;.01) with increasing DF level, which were 105.5%increase in 50% DF treatment and 139.5% increase in 100% DF treatment compared to control treatment (0% DF treatment). The tendency of increasing FHP due to DF level (50 and 100% DF) was remarkable especially in low temperature treatment (15 and 25℃). However, there was no effect of the DF level of cookerels when ET increased with 35℃, which of FHP ranged 58.3-60.6 Kca1/BW^(0.75)/day.

Two experiments were conducted to investigate the effect of feeding different levels of metabolizable energy and protein diets on growth performances, body composition and gross income of broiler chicks. The results obtained were as follows ; 1. Metabolizable energy level of diet was significantly influenced on body weight and feed efficiency. As the Metabolizable energy level of diet decreased the body weight and feed efficiency decreased proportionately. 2. Male chicks have a higher progressing tendency on body weight and feed efficiency than female chicks. Also, the body weight and feed efficiency were greatly influenced especially by the nutrient level of starter diet. (0-3 weeks) 3. When chicks were fed diet containing high energy value the body fat and abdominal fat pad size of chicks increased. 4. The highest. gross income was marked in the metabolizable energy 3200㎉ treatment of male chicks and in the 3000 ㎉ treatment of female chicks, but the high energy level of diet was not always greater in gross income than low energy level of diet.

This study was carried out to evaluate and compare the effect of feeding antibiotics on growth performance and rumen characteristics of Holstein bulls. The antibiotics used in this experiment were monensin and lasalocid as ionophores and bambermycin. The results obtained were summarized as follows: 1. The average daily gain of bulls fed antibiotics was increased by 2.4∼7.9% compared with control(P$lt;.05). Dry matter intake of bulls moderatery decreased with the addition of antibiotics except in C treatment (bambermycin group). 2. The feed efficiencies of bulls fed antibiotics were increased by 6.1∼6.7% compared with the control. 3. Digestible crude protein and total digestible nutrient requirements per ㎏ body weight gain decreased 6.07.8% by the addition of antibiotics. 4. Contents of total volatile fatty acid and propionate in the rumen were higher in bulls fed antiobiotics than in control. The acetate/propionate ratio of bulls fed antibiotics decreased compared with control. 5. Numbers of E. coil colony units in feces decreased with addition of antibiotics.

This study was carried out to evaluate the effect of feeding probiotics on growth performance, rumen characteristic and blood composition of calves. [his experiment was carried out 6 weeks employing 4 month old Holstein male calves. The results obtained can be summarized as follows; 1. The average daily gain was increased 10 to 18 percent in calves fed probiotic or probiotic plus antibiotic compared with control (p$lt;.05). Dry matter intake was also increased in calves led probiotic and antibiotic (p $lt;.05). 2. Average improvement of feed efficiency was 8 percent in calves fed only probiotic or both probiotic and antibiotic compared with control. 3. Throughout the experimental period, the number of scouring days were slightly decreased with addition of probiotics. Number of E. Coli colony units were also decreased in calves fed probiotics. 4. Ruminal pH was not altered by addition of prohiotics. However, total volatile fatty acids and individual acids (acetate and propionate) production were higher in calves fed probiotic than control. Thus C/C ratio was affected by addition of prohiotics. 5. Blood components did not differ between treatments except for increased blood glucose in both calves fed probiotics and probiotic plus antibiotic.
