This study was conducted to compare the growth performance and carcass evaluation of Jeju native cattle (JNC) and its crossbreds (CBK = 25 JNC: 50 Charolais: 25 Brahman and BCBK = 62.5 JNC: 25 Charolais: 12.5 Brahman) fed for a short fattening period. Eight male calves each of JNC (80.$40{\pm}10$), CBK ($113.50{\pm}12.3$), and BCBK ($100.3{\pm}9.5$) were weaned at 4 month of age and were fed similar diets for 18 months of their age. All animals were fed a growing ration until 12 months of age and thereafter switched to a fattening ration for a period of 6 months. Final body weight (BW) and BW gain were significantly higher in CBK and BCBK compared with JNC. The CBK and BCBK gained 27.42% and 25.99% more BW, respectively, compared with JNC. The CBK and BCBK animals consumed significantly less DM than JNC to gain a unit of BW. Body weight gain, DM intake and feed conversion efficiency were similar between CBK and BCBK. Weight of hot and cold carcass, ribs, boneless meat and Longissimus dorsi muscle area were significantly different among JNC and its crossbreds. The heaviest carcass was observed in CBK followed by BCBK and JNC. Carcass, chest and femur lengths were greater in CBK and BCBK compared with JNC. Chest width, chest depth and hip width were similar in JNC and its crossbreds. Femur width was significantly greater in CBK compared with BCBK and JNC. Femur depth and chest girth were significantly greater in CBK and BCBK compared with JNC. Weight and fat yield in different carcass cuts were greater in crossbreds compared to JNC. Percent moisture, crude ash, and crude protein of meat were similar in JNC and its crossbreds. Percent crude fat in beef was significantly greater in JNC compared with its crossbreds. Beef shear force value, percent water holding capacity, juiciness and tenderness were significantly greater for JNC compared to its crossbreds. In conclusion, CBK and BCBK have shown greater growth rates and produced heavier carcasses with good degree of fatness when compared with JNC.

Background: Preventing oxidative stress in heat stressed animals may be possible by increasing antioxidant defence via exogenous administration of antioxidant substrate and/or its precursors. The study aimed to investigate the effect of Soursop juice in mitigating oxidative stress induced by heat stress in rabbit. Methods: Sixty mixed breed rabbit bucks aged 12-18 months old with the average weight of $1826{\pm}8.35$ g/rabbit, randomly allotted to experimental treatments of four replicates each, in a completely randomized design during high-temperature humidity index in Ado Ekiti, Southwest Nigeria. Soursop juice (SSJ) was administered via oral drenched daily per kg body weight (BW), to designated treatment 1 to 5; $0.55mlkg^{-1}BW$ distilled water (control), $0.55mlkg^{-1}BW$ SSJ, $1.11mlkg^{-1}BW$ SSJ, $1.67mlkg^{-1}BW$ SSJ and $2.22mlkg^{-1}BW$ SSJ, respectively. Fastened blood samples were collected at days 28 and 56, and assay for serum protein, cholesterol, triglycerides, superoxide dismutase, catalase, reduced glutathione and lipid peroxidation using standard procedures. Result: Result revealed that SSJ demonstrated hypocholesterolemic effect in a dose-dependent manner throughout the study. Effect of chronic administration of SSJ to heat stressed rabbits proved beneficial, as SSJ reduced serum lipid peroxidation and enhanced antioxidant activity over 8 weeks. Conclusion: Administration of soursop juice to heat-stressed bucks at $2.22mlkg^{-1}BW$ offered optimum antioxidant defense against oxidative stress.

Objective: The objective of this study was to investigate the net micromineral (Cu, Fe, Mn, Zn) requirements for maintenance and growth of Dorper×Jinzhong crossbred ewe lambs at their latter fattening period. Methods: Thirty 1/2 Dorper × 1/2 Jinzhong crossed F1 ewe lambs (35±0.5 kg of body weight [BW]) were used and divided into five groups in a randomized design for a comparative slaughter trial. At the beginning of the experiment, six lambs were randomly selected and slaughtered at 35 kg BW to determine their initial body composition. When their BWs reached 43 kg, another six lambs fed ad libitum were slaughtered to serve as an intermediate slaughter group. The retained eighteen lambs were randomly distributed into three groups and offered one type of feed at 100%, 65%, and 40% of the ad libitum intake. When the lambs fed ad libitum reached a BW of 50 kg, the three groups were slaughtered. The body composition (muscle, fat, bone, blood with viscera, skin, and wool) were weighted, ground, mixed, and subsampled for mineral content analysis. Results: The net maintenance requirements of Cu, Fe, Mn, and Zn were 0.017, 0.160, 0.004, and 0.067 mg/kg BW/d, respectively, and the net growth requirements per 100 grams of average daily gain ranged from 0.48 to 0.51 mg of Cu, 2.63 to 2.17 mg of Fe, 0.12 to 0.15 mg of Mn, and 2.07 to 2.00 mg of Zn, respectively, for Dorper × Jinzhong crossed ewes from 35 to 50 kg BW. Conclusion: Our results suggest that the micromineral requirements for both maintenance and growth of Dorper × Jinzhong crossbred ewe lambs were quite different from the recommendations of NRC (2007), except for Zn.

당뇨병의 합병증 중 지질대사성 질환으로 유도되는 대사경로를 규명하고자 6주령의 흰쥐(Sprague-Dawley) 24마리를 3군으로 나누어 4주간 chemical pure diet로 사육하였다. 당뇨병을 유발하고자 alloxan을 20 mg/kg BW 또는 40 mg BW를 매주 1회 투여하였다. 혈당치를 측정하여 당뇨증상을 확인하였으며 혈청 및 간의 지질수준과 각 조직의 지방산 조성을 측정하여 당뇨병에 의한 지질대사의 변화를 비교 검토하였다. Alloxan 40 mg 투여군에서 심한 당뇨병 유발로 체중감소가 크게 나타났으며, 식이섭취량과 간중량/100 g BW도 다른 군에 비하여 유의적으로 높았다. 혈당의 변화는 alloxan 40 mg/kg BW 투여한 군이 다른 군에 비해 약 2배정도로 높게 나타나 당뇨병이 유발되었음을 확실하게 알 수 있었다. 혈청지질에서 cholesterol 함량은 alloxan 40 mg/kg BW 투여한 군에서 다른 군보다 다소 증가된 경향을 보였다. Triglyceride도 역시 alloxan 투여군에서 높은 경향으로 나타났다. 혈청 HDL-cholesterol은 군간의 유의적인 차이가 없었으며 HDL-/total cholesterol 비율도 군간에 유의적인 차이는 없었으나, 다른 군보다 alloxan 40 mg/kg BW을 투여한 군이 다소 높은 경향이었다. 간 지질에서 cholesterol 함량은 alloxan 40 mg/kg BW 투여군이 다른 군에 비해 유의적으로 낮았다. Triglyceride 함량은 군간에 유의적인 차이가 없었다. 각 조직의 인지질 지방산 조성을 보면 alloxan 40 mg/kg BW 투여군에서 lionleic acid는 증가하고 반면 arachidonic acid는 감소되어 그 결과 arachidonic/linoleic acid의 비율이 낮은 경향을 보였으며 특히 혈청과 비장에서는 그 경향이 뚜렷하여 유의적인 차이를 나타냈다. 이상의 결과를 종합하면, 당뇨병이 유도된 흰쥐에서 간의 중량 및 혈청의 지질이 증가되었고, 조직의 인지질에서 desaturation이 억제되었으므로 그로 인하여 지질대사에 관련된 합병증이 유도되는 것으로 판단되었다.

Objective: Feed energy required for pigs is first prioritized to meet maintenance costs. Additional energy intake in excess of the energy requirement for maintenance is retained as protein and fat in the body, leading to weight gain. The objective of this study was to estimate the metabolizable energy requirements for maintenance ($ME_m$) by regressing body weight (BW) gain against metabolizable energy intake (MEI) in growing pigs. Methods: Thirty-six growing pigs ($26.3{\pm}1.7kg$) were allotted to 1 of 6 treatments with 6 replicates per treatment in a randomized complete block design. Treatments were 6 feeding levels which were calculated as 50%, 60%, 70%, 80%, 90%, or 100% of the estimated ad libitum MEI ($2,400kJ/kg\;BW^{0.60}\;d$). All pigs were individually housed in metabolism crates for 30 d and weighed every 5 d. Moreover, each pig from each treatment was placed in the open-circuit respiration chambers to measure heat production (HP) and energy retained as protein ($RE_p$) and fat ($RE_f$) every 5 d. Serum biochemical parameters of pigs were analyzed at the end of the experiment. Results: The average daily gain (ADG) and HP as well as the $RE_p$ and $RE_f$ linearly increased with increasing feed intake (p<0.010). ${\beta}$-hydroxybutyrate concentration of serum tended to increase with increasing feed intake (p = 0.080). The regression equations of MEI on ADG were MEI, $kJ/kg\;BW^{0.60}\;d=1.88{\times}ADG$, g/d+782 ($R^2=0.86$) and $ME_m$ was estimated at $782kJ/kg\;BW^{0.60}\;d$. Protein retention of growing pigs would be positive while REf would be negative at this feeding level via regression equations of $RE_p$ and $RE_f$ on MEI. Conclusion: The $ME_m$ was estimated at $782kJ/kg\;BW^{0.60}\;d$ in current experiment. Furthermore, growing pigs will deposit protein and oxidize fat if provided feed at the estimated maintenance level.

Three experiments were conducted with broilers to study the effects of early feed restriction. In all studies, treatments were represented by three replicated floor pens, each containing 20 birds. In Experiment 1, broilers were fed at 0.75 kcal ME/g BW/sup0.67 for 3 d, 1.5kcal m/E BW/sup0.67 for 5 d or 2.25 kcal ME/g BW/sup0.67 for 7 d, all imposed beginning at 7 d of age. Birds were smaller following feed restriction(P<0.05), although growth compensation occurred, and at 49 d all restricted birds were same(P>0.05) to full-fed control buds in body weight. Growth compensation was associated with improved feed conversion(P<0.05), although carcass composition was unchanged. In a second study, all birds were fed at 0.75 kcal ME/g BW/sup0.67 for 3 or 5 d, starting at either 4, 7, or 10 d of age. When feed restriction was applied for shorter periods of time, growth compensation occurred(P>0.05). With more severe feed restriction, birds were smaller(P<0.05) at 49 d compared to control. Feed conversion was improved following prior feed restriction(P<0.05, 4 to 49). In a third trial, broilers were fed a starter diet diluted with 50% rice hulls. Birds failed to consume enough of this diluted feed, and so were initially smaller, However 49 d weight was not affected (P>0.05). When periods of 24 h feed withdrawal were imposed in conjunction with the diluted diets, birds were under weight at 49 d. It is concluded that physical feed restriction at 0.75 to 1.5 kcal ME/g BW$\^$0.67 imposed for 3 to 5 d in the early life currently presents the best option as a means of controlling broiler growth so as to improve feed efficiency.

The objective of this study was to identify the effect of early weaning on body weight change, milk production and the return to estrus in Awassi ewes. Twenty multiparous winter-lambing Awassi ewes were randomly assigned to either suckled (S, n=10) or non-suckled (NS, n=10) groups in a completely randomized design. Lambs in the NS group were removed from their dams on day 2 postpartum (PP). Animal body weights (BW) and body condition scores (BCS) were recorded at the beginning of the study and every 3 weeks thereafter until the end of the experiment. Milk production was estimated by machine milking at weekly intervals for 4 weeks beginning on d 11 PP. Blood samples were collected from each ewe every third day for 4 weeks beginning on day 15 PP. Initial body weight was similar for both treatments. By the end of the experiment, NS ewes gained an average of 1.8${\pm}$1.0 kg while S ewes lost an average of 7.0${\pm}$1.0 kg (p<0.001). Body condition scores followed a trend similar to that observed for BW and was greater (p<0.001) in the NS ewes. Significant correlation existed (p<0.01) between BW and BCS (r=0.77). The first milk production recording for both suckled and non-suckled was similar. Later recordings, however, showed that the S group had greater milk production (p<0.01) compared with the NS group. Lambs in the NS group were heavier (p<0.05) than those in the S group on d 10 PP. By the end of the study, lamb weights in the NS group were significantly lower (p<0.001) when compared with S group. The first rise in plasma progesterone ($P_{4}$) occurred earlier (p<0.05) in the NS than S ewes (day 27.0${\pm}$2.2 vs. 34.0${\pm}$2.2 postpartum, respectively). All of the NS ewes (10/10) and 60% (6/10) of the S ewes expressed estrus following ram introduction (p<0.05). Results of the current study indicate that non-suckled ewes gained more weight and displayed ovarian activity earlier than suckled ewes. Early lamb removal can be used to obtain biannual lambing in Awassi sheep.

BACKGROUND/OBJECTIVES: The type of sweet snack incorporated into an energy-restricted diet (ERD) may produce differential effects on metabolic improvements associated with body weight (BW) loss. This study compared effects of incorporating either twice daily energy-controlled dark chocolate snacks plus once daily sugar-free cocoa beverage (DC) to non-chocolate snacks plus sugar-free non-cocoa beverage (NC) into an ERD on BW loss and metabolic outcomes. MATERIALS/METHODS: In an 18-week randomized comparative trial, 60 overweight/obese premenopausal women were assigned to DC (n = 30) or NC group (n = 30). Dietary intake was measured at baseline and week 18, and BW, anthropometrics, blood pressure (BP) and serum glucose, insulin and lipid concentrations were measured at baseline, and weeks 6, 12 and 18. Data were analyzed using repeated measures ANOVA. RESULTS: Using intention-to-treat analysis, women in DC and NC groups reduced energy intake (both P < 0.001) and lost $4.4{\pm}0.6kg$ and $5.0{\pm}0.9kg$ (both P < 0.001), respectively. Both groups lowered systolic and diastolic BP [DC = 2.7 (P < 0.05), 2.7 (P < 0.01); NC = 3.4 (P < 0.01), 4.2 (P < 0.01) mmHg, respectively]. Glucose and insulin concentrations decreased by 0.72 mmol/L (P < 0.001) and 13.20 pmol/L (P < 0.01) in DC group and by 0.83 mmol/L (P < 0.001) and 13.20 pmol/L (P < 0.01), respectively, in NC group. Total cholesterol increased in NC group (P < 0.05), with no significant lipid changes in DC group. There were no significant differences in biomarker outcomes between groups. CONCLUSIONS: Overweight/obese premenopausal women following an 18-week ERD that included either DC or NC sweet snack and sugar-free beverage lost equivalent amounts of BW and improved BP measurements and glucose and insulin concentrations.
