| 1 | Effects on Growth Performance and Feed Digestibility of Hainan Black Pigs by Adding Lysine in Low Protein Diet显示文摘[Objective] The paper was to study the effects on growth performance and feed digestibility of Hainan black pigs by adding lysine in low protein diet.[Method] A total of 36 Hainan black pigs with the body weight of(46.34 ±3.06) kg were randomly divided into three groups:control group(protein level 15%,lysine level 0.83%),experimental group I(protein level 13%,0.83%),and experimental group II(protein level 13%,lysine level 1.03),each group had three replicates of four pigs.The trial lasted 35 d.[Result] The growth performance of Hainan black pig in group II had no significant difference with that in control group(P>0.05).The apparent digestibility of crude protein and phosphorus of Hainan black pigs in Group II increased significantly(P<0.05),which were increased by 10.08% and 11.85% respectively compared to the control group;the apparent digestibility of calcium was increased,but the difference was not significant(P>0.05).[Conclusion] It will not reduce the growth performance of Hainan black pig when the protein level of diet is reduced by 2% and the lysine level is increased to 1.03%.It is recommended that the diet can be used in the production of Hainan black pig. | Wei Limin Liu Quanwei Sun Ruiping Zheng Xinli Wang Feng Tan Shuyi Huang Lili Xing Manping | 2018 | Animal Husbandry and Feed Science2018，10，2： | 4 |
| 2 | Effect of Pelleted Total Mixed Ration on Production Performance and Serum Biochemical Index of Growing Hainan Black Goats显示文摘[Objective] The paper was to investigate effects of pelleted total mixed ration on production performance and serum biochemical index of growing Hainan black goats.[Method] Twenty-four growing Hainan black goats with the same genetic backgrounds and similar initial weight of(10.05±0.049) kg were randomly assigned into two treatments, and supplied with Juncao + concentrate(control group), pelleted total mixed ration(experimental group), respectively. The trial lasted 50 d.[Result] The final weight, daily gain and feed intake of experimental group were significantly higher than those of control group(P<0.05), but the feed/gain ratio of experimental group was markedly lower than that of control group(P<0.05). Compared with the control group, the gross profit of experimental group significantly increased( P <0.05).[Conclusion] Pelleted total mixed ration led to better production performance of growing Hainan black goat. | Liu Quanwei Wang Feng Wei Limin Huang Lili Sun Ruiping Xing Manping Zheng Xinli | 2019 | Animal Husbandry and Feed Science2019，11，1： | 4 |
| 3 | Effects of Dietary Crude Fiber Levels on Growth Performance and Serum Biochemical Index of Dingan Geese Aged from 35 to 70 Days显示文摘[Objective] The study was carried out to investigate the effects of dietary crude fiber on growth performance and serum biochemical in-dex of Dingan geese aged from 35 to 70 days.[Method] A total of 120 Dingan geese on day 28 with the same genetic background and similar initial weight(1 384.83.73±0.76 g) were randomly assigned into 3 groups, with 4 replicates per group and 10 geese per replicate. Geese were fed the diets containing 4.29%, 5.29% and 6.29 % crude fiber, respectively. The experiment lasted 35 d.[Result] Final weight and daily gain of 5.29 %CF group were significantly higher than those of 6.29 % CF group(P<0.05);Feed intake was markedly higher than those of 4.29% and 6.29 % CF groups(P<0.05);Feed gain ratio was significantly lower than that of 6.29 % CF group(P<0.05). Compared with 4.29% and 6.29 % CF groups, serum albumin concentrations of 5.29 % CF group increased significantly(P<0.05), while serum total protein and globin contents were higher(P>0.05), but serum uric acid level was lower(P>0.05).[Conclusion] 5.29 % crude fiber could lead to higher growth performance of Dingan geese. | Liu Quanwei Wang Feng Wei Limin Lin Dajie Xing Manping Yang Shaoxiong Sun Ruiping Ye Baoguo | 2019 | Animal Husbandry and Feed Science2019，11，1： | 3 |
| 4 | Slaughtering Performance and Meat Quality of Hainan Black Goat and Its Hybrid Offsprings with Nubian Black Goat显示文摘In order to compare the slaughter performance and meat quality of Hainan black goats and hybrid offsprings of Nubian Black Goat and Hainan Black Goat, six 7-month-old Hainan black goats and six hybrid offsprings were selected to determine slaughter performance and muscle quality. The results showed that hybridization of Nubian black goat and Hainan black goat significantly improved the production performance and slaughter performance of hybrid offsprings (P>0.05). The meat quality of F1 hybrid black goat had no significant difference with that of Hainan black goat except for the hardness and elasticity (P<0.05). Therefore, the crossbred progenies of Nubian black goat and Hainan black goat have advantages in meat yield and meat performance, and the main meat quality indexes are not significantly different, which meets the market requirements for high-yield and high-quality hybrid combinations, and can be used for cross promotion. | Wei Limin Sun Ruiping Liu Yan Liu Ruina Liu Quanwei Zheng Xinli Wang Feng Huang Lili Xing Manping | 2019 | Animal Husbandry and Feed Science2019，11，2： | 2 |

| 7 | Meat Quality Characteristics of Hainan Black Goat and Its Hybrid with Nubian Black Goat显示文摘[Objective] The paper was to understand the meat quality characteristics of Hainan black goat and its hybrid with Nubian black goat. [Method]Four 6-month-old Hainan black goats and Hainan black goat × Nubian black goat F1 were slaughtered respectively,and the contents of crude protein,total fat,moisture,amino acids,mineral elements( Se,Zn and Mn) and fatty acid were determined. [Result]There was no significant difference in total fat,crude fat and moisture content in muscle of Hainan black goat × Nubian black goat F1 and Hainan black goat( P > 0. 05). The Fe content in the muscle of Hainan black goat × Nubian black goat F1 was significantly higher than that in Hainan black goat( P < 0. 05). There was no significant difference in EAA,NEAA,TAA and FAA between Hainan black goat × Nubian black goat F1 and Hainan black goat( P > 0. 05). The C17∶ 0 methyl heptadecanoate content in the muscle of Hainan black goat × Nubian black goat F1 was extremely lower than that in Hainan black goat( P < 0. 01),but the saturated fatty acid content and total unsaturated fatty acid content in the muscle of Hainan black goat × Nubian black goat F1 was lower than that in Hainan black goat( P > 0. 05). [Conclusion]The meat quality characteristics of Hainan black goat × Nubian black goat F1 had little difference with its female parent,and the goal of breeding had been basically achieved. | Zheng Xinli Sun Ruiping Wei Limin Wang Feng Chao Zhe Liu Hailong Liu Quanwei Huang Lili Xing Manping | 2017 | Animal Husbandry and Feed Science2017，9，5： | 0 |
| 8 | Effect of Pelleted Total Mixed Ration with Different Concentrate-roughage Ratios on Production Performance and Serum Biochemical Parameters of Fattening Hainan Black Goats显示文摘[Objective] This paper was to study effects of pelleted total mixed ration with different concentrate-roughage ratios on production performance and serum biochemical parameters of fattening Hainan black goats.[Method] Thirty-six fattening Hainan black goats with the same genetic background and similar initial weight of(14.08±0.13) kg were randomly assigned into three treatments. Goats were fed with Juncao + concentrate(control group), pelleted total mixed ration I(concentrate: roughage 50 ∶50, group Ⅰ) and Ⅱ(concentrate: roughage 45∶55, group Ⅱ), respectively. The test lasted 45 d.[Result] The final weight, daily gain and feed intake of rams in experimental group Ⅰ were significantly higher than those of control group and experimental group Ⅱ(P<0.05);the final weight and daily gain of rams in experimental group Ⅰ were also markedly higher than those of experimental group Ⅱ(P<0.05);the feed/gain of rams in experimental group Ⅰ was significantly lower than those in control group and experimental group Ⅱ(P<0.05). The feed gain cost of rams in experimental group Ⅰ was markedly lower than that in experimental group Ⅱ( P<0.05), but was significantly higher than that in experimental group Ⅰ(P<0.05);the gross profit of rams in experimental group Ⅰ was significantly higher than those in control group and experimental group Ⅱ(P<0.05). Compared with control group and experimental group Ⅱ, the serum total protein and glucose lev-els in experimental group Ⅱ increased significantly(P<0.05), but the urea nitrogen content reduced(P>0.05).[Conclusion] When the concentrateroughage ratio of pelleted total mixed ration was 50∶50, the fattening effect of Hainan black goat was better, and the serum total protein and glucose levels were evidently improved. | Liu Quanwei Wang Feng Wei Limin Tan Shuyi Sun Ruiping Huang Lili Xing Manping Zheng Xinli | 2019 | Animal Husbandry and Feed Science2019，11，1： | 0 |
