The aim of the present work was to study the effects of a polyherbal supplement on cross bred does, starting from the last month of pregnancy to weaning, on milk yield, kid birth weight and growth rate. Thirty does were divided into three treatments of ten each in individual pens: low level supplementation (LS), high level supplementation (HS) and non-supplemented treatment (NS) as control. Low supplemented goats were given 125 mg/kg BW/d of polyherbal combination; high supplemented goats were given 250 mg/kg BW/d. The study was carried out in 2008. Fifty-nine kids were born from all the experimental animals. There was no difference on milk yield between supplemented groups and control (p>0.05), although polyherbal supplementation had positive effect on litter birth weight and growth rate compared to control. Weaning weights were higher (p<0.001) in LS and HS compared to NS does. In both supplemented treatments compared to control, mortalities and morbidities were also lower in kids born. It is concluded that pre-partum to weaning supplementation increases kids growth rates and weaning weights, as well as reduces kid mortalities, but it doesn't have significant effect on milk production.

The present study was conducted to measure diurnal patterns in the flow of soluble non-ammonia nitrogen (SNAN) fractions in the liquid phase of digesta entering the omasum of cows fed grass-red clover silage supplemented with barley and rapeseed meal. Four ruminally cannulated cows were fed, in a 4×4 Latin square design, grass-red clover silage alone (GS) or supplemented with (on a DM basis) 6.0kg/d of barley grain, 2.1kg/d of rapeseed meal or 6.0kg/d of barley and 2.1kg/d rapeseed meal. Omasal digesta was taken using an omasal sampling system at 1.5h intervals during a 12h feeding cycle, and SNAN fractions (free AA, peptide and soluble protein) in the omasal digesta were assessed using ninhydrin assay. Dietary supplementation numerically increased the mean flow of SNAN fractions relative to GS diet despite the lack of statistical significance. Diurnal patterns in the flow of peptide entering the omasum during a 12h feeding cycle appeared to be highest immediately after feeding, declined by 10.0h post-feeding and slightly increased thereafter. In SNAN fractions, the flow of peptide was higher for supplemented diets than for GS diet throughout the feeding cycle. Based on the microbial contribution to total SNAN using 15N, diurnal patterns in the flow of dietary SNAN for dietary supplemented diets appeared to be higher compared with GS diets. Present results may conclude that peptide flow is quantitatively the most important N in SNAN fractions and that dietary supplementation can increase peptide flow entering the omasal canal.

This study was carried out to investigate the effects of Cervi Pontotrichum cornu and Carthami semen on the serum osteocalcin level, bone mineral density, bone trabecular area and cortical thickness index in ovariectomized rats. Femal Sprague-Dawley rats were divided into 5 groups. Non-ovariectomized groups were divided into commertial diet fed(normal group) and calcium free basal diet fed(sham operation group). Ovariectomized groups were divided into 3groups, calcium free basal diet fed group(control group or ovariectomized group), 10% Cervi Pontotrichum cornu supplemented diet fed group and 10% Carthami semen supplemented diet fed group. After 4 weeks diet fed, serum osteocalcin level, bone mineral density, bone trabecular areas and cortical thickness index were analyzed. The bone mineral density and bone trabeculae area were significantly increased by Cervi Pontotrichum cornu and Carthami semen supplemented diet fed groups. The osteocalcin level was significantly decreased by Cervi Pontotrichum cornu and Carthami semen supplemented diet fed groups. The trabecular area(%) in epiphysis of tibia was significantly increased by Cervi Pontotrichum cornu and Carthami semen supplemented diet fed groups. The cortical thickness index in distal diaphysis of tibia was significantly increased by Cervi Pontotrichum cornu and Carthami semen supplemented diet fed groups. the alkaline phosphatase level was significantly decreased by Cervi Pontotrichum cornu and Carthami semen supplemented diet fed groups. These results suggest that Cervi Pontotrichum cornu and Carthami semen might have inhibitory effects on osteoporosis by increasing bone mineral density and accerelating bone formation in ovariectomized rats.

Twenty four weaner lambs, eight each of Marwari, Patanwadi and Merino${\times}$Patanwadi breeds (9.9 to 10.8 kg) were randomly divided into two dietary treatments on body weight basis Viz. $T_1$-conventional (Maize-38%, GN Cake-25%, Rice Polish-24%, Jaggery solution-10%, Mineral mixture-3%) and $T_2$-supplemented non conventional group (GN Cake-25%, Rice Polish-14%, Mango seed kernel-25%, Babul Pods chuni-23%, Jaggery solution-10%, Mineral mixture-3%). The Jaggery solution was prepared by mixing 6.5 kg Jaggery and 3.5 kg water. The average final body weight at the end of the experiment was recorded to be $19.33{\pm}0.76$ and $19.72{\pm}0.8kg$ in conventional and non-conventional groups, respectively. The total dry matter intake (DMI) during the entire experiment period was recorded to be $89.56{\pm}5.19$ and $95.08{\pm}1.06$ (kg/head) and $532.83{\pm}9.94$ and $566.75{\pm}10.49g/d$ in conventional and nonconventional groups, respectively. The body weight gain and body measurements did not influenced by diet. The ration effect was found to be significant when the DMI was expressed in terms of g/d. The crude protein (CP) and digestible crude protein (DCP) intake/head and per kg gain observed during experiment under conventional and non-conventional treatment group did not differ from each other. However, the total digestible nutrients (TDN) intake per kg gain was significantly (p<0.05) higher in supplemented non-conventional group. The intake values of DCP and TDN were more or less in agreement with Indian Council Agricultural Research (1985) recommendations. The estimated total feed cost (Rs./animal) for experimental lambs was $274.16{\pm}8.57$ and $242.67{\pm}5.10$ in conventional and non- group, respectively. The non-conventional group had significantly (p<0.05) lower feed cost (11.6%). The return as percent of feed cost and feed cost/kg dressed weight were $92.89{\pm}5.58$ (%) and Rs. $35.40{\pm}1.11$ and $122.61{\pm}5.06$ (%) and Rs.$30.47{\pm}1.71$ in conventional and non-conventional group (p<0.05), respectively which is the reflection of significantly lower total feed cost incurred during feeding in non-conventional group. Lambs fed non-conventional based diet had similar live weights as those fed conventional diets but costed less money to achieve those weights.

The objective of this work was to evaluate the nutritional parameters of young bulls supplemented with different ratios of protein: carbohydrate on tropical pastures from 4 until 18 months old. Fifty-five non-castrated beef calves ($138.3{\pm}3.4kg$, 90 to 150 d of age) were used. The calves (young bulls) were subjected to a 430-d experimental period encompassing 4 seasons. The treatments were as follows: control, only mineral mixture; HPHC, high protein and high carbohydrate supplement; HPLC, high protein and low carbohydrate supplement; LPHC, low protein and high carbohydrate supplement; and LPLC, low protein and low carbohydrate supplement. The amount of supplement was adjusted every 28 d. Dry matter (DM) intake was higher in the dry-to-rainy transition and rainy seasons for all nutritional plans. Non-supplemented animals had lower intakes of DM and total digestible nutrients (TDN) than supplemented young bulls in all seasons. Although differences in DM intake were not observed between supplemented animals, the supplements with high carbohydrate (HPHC and LPHC) had lower forage intake during suckling (rainy-to-dry transition season) and in the rainy season. However, the HPHC treatment animals had higher intake and digestibility of neutral detergent fiber. It can be concluded that supplementation with high protein levels (supplying 50% of the crude protein requirement) provide the best nutritional parameters for grazing young bulls in most seasons, increasing intake and digestibility of diet, and these effects are more intense when associated with high carbohydrate levels level (supplying 30% TDN requirement).

Two inorganic (zinc sulfate and zinc oxide) and three organic (zinc acetate, zinc-methionine, and zinc-lysine) zinc sources were evaluated for their effects on the performance and carcass characteristics of broiler chicks. The birds were randomly assigned to one control (non-supplemented) and 15 treatment (supplemented) groups consisting of four replicates of 10 chicks each in a $5{\times}3$ factorial arrangement of treatments (five zinc sources and three supplemental zinc levels). Birds were kept in floor pens in a temperature-controlled room from 1 to 42 d of age and fed a non-supplemented basal diet (control) or the basal diet supplemented with 40, 80 or 120 mg/kg of Zn as mentioned sources. Dietary zinc source had considerable effect on feed intake in all experimental periods. Increasing Zn level from 80 to 120 mg/kg decreased the average feed intake in the growth stage (p<0.01) and also in the entire experimental period (p<0.001). Similarly, the average daily gain during the entire trial period was affected by the type of Zn source (p<0.001) and supplemental level (p<0.01). One degree of freedom contrast comparisons showed that the inclusion of organic zinc sources into the diets caused significant increases in feed intake and body gain when compared with inorganic counterparts. Except in wk 1, dietary supplementation with organic sources improved (p<0.05) feed conversion ratio; FCR values were not affected by dietary Zn source or supplementation level. Breast meat yield increased with supplemental levels of organic Zn sources; however, other carcass parameters were not affected by dietary Zn source. On the other hand, organic versus inorganic zinc supplementation caused a significant increase in liver, breast and carcass weight percentages. The present findings suggest that supplemental levels of organic Zn compounds had beneficial effects on broiler performance, and Zn requirements can be reduced using these feed supplements in poultry rations.

In this study, we evaluated the efficacy of a commercial vaccine stress-relieving agent (Anti VS-2 injection) to reduce the adverse effects of foot-and-mouth disease (FMD) vaccination site in 120 pigs on two tested pig farms. The results showed that incidence of pig with abnormal meat, size of abnormal meat and weight of discarded abnormal meat are significantly decreased in Anti VS-2 injection-supplemented FMD vaccinated pig groups (n=60) compared to the non-supplemented FMD vaccinated pig groups (n=60) (P<0.05). And the average economic loss by discard of abnormal meat were estimated 99,382 won or 21,514 won in the non-supplemented FMD vaccinated groups or in the Anti VS-2 injection-supplemented FMD vaccinated groups, respectively, showing that the cost saving effect was 78% (77,869 won). In conclusion, it is expected to reduce the incidence and severity of abnormal meat in the FMD vaccinated pigs and to contribute not only to the reduced economic loss of pig farmers but also to the promotion of food hygiene when the Anti VS-2 injection is mixed with FMD vaccine.

An experiment was conducted to study the effect of soluble protein supplements on concentration of soluble non-ammonia nitrogen (SNAN) in the liquid phase of ruminal (RD) and omasal digesta (OD) of Korean native steers, and to investigate diurnal pattern in SNAN concentration in RD and OD. Three ruminally cannulated Korean native steers in a $3{\times}3$ Latin square design consumed a basal diet of rice straw and corn-based concentrate (control), and that supplemented (kg/d DM basis) with intact casein (0.24; IC) or acid hydrolyzed casein (0.46; AHC). Ruminal digesta was sampled using a vacuum pump, whereas OD was collected using an omasal sampling system at 2.0 h intervals after a morning feeding. The SNAN fractions (free amino acid (AA), peptide and soluble protein) in RD and OD were assessed using the ninhydrin assay. Concentrations of free AA and total SNAN in RD were significantly (p<0.05) lower than those in OD. Although free AA concentration was relatively high, mean peptide was quantitatively the most important fraction of total SNAN in both RD and OD, indicating that degradation of peptide to AA rather than hydrolysis of soluble protein to peptide or deamination may be the most limiting step in rumen proteolysis of Korean native steers. Diurnal variation in peptide concentration in OD for the soluble protein supplemented diets during the feeding cycle peaked 2 h post-feeding and decreased thereafter whereas that for the control was relatively constant during the entire feeding cycle. Diurnal variation in peptide concentration was rather similar between RD and OD.

This experiment was conducted to investigate the effect of feeding TMR with or without Yukmijihwangtang meal silage on the growth performance, meat yield and quality of Hanwoo steers. Sixteen male Hanwoo steers in the late fattening period were randomly assigned to a control diet and Yukmijihwangtang meal diet, with eight heads per treatment. The supplementation of Yukmijihwangtang meal silage did not affect the feed conversion rate, ribeye area, and meat yield index of cold carcass of Hanwoo. Fat thickness of Hanwoo s loin obtained from silage supplementation was significantly lower than that of non-supplemented. Total grade in meat yield of Hanwoo from silage supplementation were higher than that of non-supplemented control. The supplementation of Yukmijihwangtang meal silage to Hanwoo decreased the marbling score significantly, but did not affect fat color, firmness, and maturity. Total grade of meat quality of Hanwoo with Yukmijihwangtang meal supplementation was lower than that of non-supplemented control. In conclusion, Yukmijihwangtang meal could be used as partial substitution (10%) in TMR for fattening cattle. However, it is considered that Yukmijihwangtang meal can be a useful feed for the periods of growing or early fattening than that of late fattening since it improved meat yield but decreased meat quality grade of Hanwoo steers.
