Level of Testosterone, Libido, and Sperm Quality of Bligon, Kejobong, and Etawah Cross-Bred Bucks
Get PDFThe aim of the study was to investigate the comparison and correlation among testosterone concentrations, libido, and sperm quality of Bligon, Kejobong, and Etawah Cross-bred (PE) bucks at similar age, feed, and season. Samples used were 9 bucks (3 Bligon, 3 Kejobong, and 3 PE) of approximately 18 months of age. The testosterone was measured by enzyme-linked immunosorbent assay (ELISA) method. Libido observation was quantified at the first time of sniffing, mounting, and finally ejaculation. Sperm was collected by using artificial vagina. The reesults showed that Kejobong’s testosterone in the morning (12.00±6.56 ng/ml) was significantly different compared to PE (6.82±4.18 ng/ml), whereas Bligon’s testosterone in the morning (9.23±4.73 ng/ml) was similar compared to Kejobong and PE. The best time of Kejobong’s libido was in the morning (6.77±5.96; 11.27±8.10, and 18.45±8.27 sec.) and in the afternoon (8.89±7.97; 11.03±8.74, and 21.05±9.60 sec.). The motility and concentrations of Kejobong’s spermatozoa (75.67±6.51% and 5838.67±140.90 x106/ml) were significantly different compared to Bligon (60.67±9.61% and 4625.33±129.72 x106/ml) and PE (63.13±8.33% and 3756.00±52.76 x106/ml. It could be concluded that Bligon and PE bucks have the similar testosterone concentration, and the libido and sperm quality of Kejobong is better than Bligon and PE bucks. Animal Production 15(2):76-82, May 201
Genetic and Non-Genetic Factors Affecting Litter Size and Birth Weight of Rabbit in Minna, Niger State, Nigeria
Get PDFAbstract. Genetic and non-genetic factors influencing litter size and birth weight of rabbit was evaluated using New Zealand White and Chinchilla breeds. Parameters measured were total number of kittens born per litter, number of litter born alive, live litter birth weight and average litter birth weight. Results of the experiment revealed that dam breed had no significant affect on total number of kittens born per litter, number of litter born alive and average litter birth weight while live litter birth weight were affected. Sire breed and month of birth did not significantly influenced all the parameters measured. Heritability estimates were low to moderate for all the traits (0.27 to 0.44), while repeatability estimates were observed to be low (0.17 to 0.26). No heritability and repeatability values were estimated for average litter birth weight of kittens due to negative genetic variance. Significant correlations were found between litter size traits and birth weight. Correlation between litter size traits and average litter birth weight, as well as live litter birth weight and average litter birth weight were observed to be non-significant.Keywords: rabbit, litter size, birth weight, genetic, non-geneticAbstrak.

Relationships Among Live Body Weight and Some Body Measurements in Sudanese Kenana Bulls
Get PDFAbstract. The phenotypic relationship between live body weight (kg) and body measurements (cm) for Sudanese bulls is explored. In this research, data from one visit survey were used to estimate the relationships between live body weight and some body measurements of Sudanese Kenana bulls. General linear model analysis with multivariate ANOVA when all physical variables were response and animal live body weight groups (kg) as independent, and simple linear Pearson's correlation were formed between live body weight (Bwt), Heart girth (HG), Heart girth at hump (HTH), Body length (Bl) and Abdominal girth (ABG). The results revealed the best linear correlation between body weight and measurements was heart girth at hump (0.65, 0.66 and 0.73) respectively, for live body weight groups. The obtained linear correlation coefficients were relatively highly accurate indicators of live body weight. This suggests that live body weight could be estimated accurately by body measurements in Sudanese Kenana Bulls. Keywords: live body weight, body measurements, correlation, Kenana bulls, Sudan Abstrak.

Performance and Haematological Indices of Broiler Chickens Fed Diet Containing Graded Level of Moist Heat Treated Gmelina arborea Seed Meal
Get PDFAbstract. Experiment evaluating the effect of moist heat treated Gmelina arborea seed meal (MHGASM) on the growth performance and hematological indices in broiler chickens was conducted using one hundred and twenty (120) two weeks old broiler chickens which were randomly allotted to four dietary treatments consisting three replicates each with each replicate containing ten birds in a complete randomized design. The feed having 0% of MHGASM was taken as the reference diet, and the three diets to which MHGASM were included at graded level of 20, 25 and 30% as T2, T3 and T4 respectively were used for the comparison with the reference diet. Birds were fed the experimental diets and water supplied adlibitum during the feeding trial that lasted for 56 days. The results showed that final body weight, weight gain and feed conversion ratio were significantly affected by the dietary treatments while feed intake was not significantly influenced by the diets. Birds fed T4 (30% MHGASM inclusion level) diet had the highest final body weight, weight gain and best feed conversion ratio. Similarly, significant differences were recorded on all the hematological parameters investigated except hemoglobin concentration of the broilers across the treatment diets. Birds fed T4 diet recorded a higher mean values in all the hematological parameters except in WBC where T3 had the highest mean value. From the result of the study, it was therefore concluded that birds fed T4 (30% MHGASM)diet had an improved performance and the inclusion of moist heat treated Gmelina arborea seed in the diet of broilers do not have any negative effect on their physiological and immune system. Thus, moist heat treated Gmelina arborea seed meal may serve as a useful alternative for protein and fiber in compounding feed for broiler chickens. Key words: Performance, hematology, moist heat treated, Gmelina arborea, broiler chickens Abstrak. Percobaan mengevaluasi pengaruh tepung Gmelina arborea (jati) yang diuapkan (MHGASM) pada kinerja pertumbuhan dan indeks hematologis ayam broiler dilakukan menggunakan 120 ekor ayam broiler berumur 2 minggu yang secara acak dibagi ke dalam empat perlakuan pakan. Perlakuan diulang tiga kali, setiap ulangan terdiri atas 10 ayam, dan menggunakan Rancangan Acak Lengkap. Pakan dengan 0% MHGASM dijadikan pakan kontrol, dan tiga pakan mengandung MHGASM sebanyak 20, 25 dan 30% sebagai T2, T3 dan T4 digunakan sebagai pembanding pakan kontrol. Ayam mengkonsumsi pakan percobaan dan air diberikan ad libitum selama 56 hari percobaan. Hasil menunjukkan bahwa bobot akhir, penambahan bobot dan tingkat konversi pakan dipengaruhi oleh perlakuan pakan, sedangkan asupan pakan tidak dipengaruhi oleh pakan. Ayam yang diberi pakan T4 (30% MHGASM) memiliki bobot akhir dan penambahan bobot tertinggi, serta tingkat konversi pakan terbaik. Perbedaan nyata juga terdapat pada semua parameter hematologis kecuali konsentrasi hemoglobin pada broiler disetiap perlakuan pakan. Ayam yang diberi pakan T4 (30% MHGASM) memiliki nilai rataan tertinggi di semua parameter hematologi kecuali sel darah putih yang rataan tertingginya pada pakan T3 (25% MHGASM). Dari hasil penelitian disimpulkan bahwa ayam yang diberi pakan T4 menunjukkan peningkatan kinerja dan penambahan tepung jati yang diuapkan pada pakan broiler tidak menimbulkan dampak negatif terhadap fisiologi dan sistem kekebalan tubuh. Dengan demikian, tepung jati yang diuapkan dapat digunakan sebagai pengganti protein dan serat dalam pakan ayam broiler. Kata kunci: Kinerja, hematologi, penguapan, Gmelina arborea, ayam broile
Effect of Processing Method on the Quality of Palm Kernel Cake: Chemical Composition and Nutrient Utilization in Enzyme Supplemented Diets
Get PDFAbstract. The feed value of palm kernel cake (PKC) from two expeller sites and two hydrothermal production facilities were assessed using 30 laboratory rats as a model. Following chemical analysis, the PKC were incorporated at 0% (control, CON) or 35% (w/w) into isonitrogenous maize-based diets (2.9% N, DM basis) and fed to individually caged albino rats for 28 day. All PKC diets included 0.5% (w/w) Alzyme Vegpro (Alltech Canada, Guelph, ON). PKC from expellers (E1, E2) contained more fatty acids (FA) and less crude protein (CP) than did PKC from hydrothermal production (H1, H2), averaging 15.8% vs 7.7% FA and 13.3% vs. 19.7% CP (DM basis), respectively. Lauric, oleic, myristic and palmitic acids were predominant in PKC, accounting for 84% of total FA. E1 and E2 had higher essential amino acid contents (average 67.1% of total AA) than did H1 or H2 (average 64.1%). Gain and feed efficiency (FE; feed/gain) were similar between rats fed E1 or E2 diets and those fed CON (2.1 and 2.2 g/d vs. 2.2 g/d; 4.7 and 4.3 g/d vs. 5.3, respectively), but were reduced in rats fed H1 or H2 diets (1.5 and 1.3 g/d gain; 7.1 and 7.0 FE) compared with CON. This study indicated that expeller-produced PKC could potentially be included in maize-based starter diets for pigs at up to 35% with no adverse effects on growth. Key words: Amino acid, fatty acid, expeller, hydrothermal Abstrak. Nilai pakan PKC dari dua expeller dan dua fasilitas produksi hidrotermal diukur menggunakan 30 mencit sebagai model. PKC dianalisa secara kimiawi dengan kadar 0% (kontrol, CON) atau 355 (w/w) ke dalam pakan berbahan dasar jagung isonitrogen (2.9% N, BK) dan diberikan kepada mencit albino yang dikandangkan secara individu selama 28 hari. Semua pakan PKC mencakup 0.5%(w/w) Alzyme Vegpro (Alltech Canada, Guelph, ON). PKC expeller (E1, E2) mengandung lebih banyak asam lemak (FA) dan lebih sedikit protein kasar (PK) daripada PKC dari produksi hidrotermal (H1, H2), dengan kisaran 15,8% vs 7,7% FA dan 13,3% vs 19,7% PK (berdasarkan BK). Asam laurat, oleat, miristat dan palmitat mendominasi PKC, mencakup 845 dari total asam lemak. E1 dan E2 mempunyai kandungan asam amino esensial (rata-rata 67,1 dari total asam amino) daripada H1 dan H2 (rata-rata 64,1%). Efisiensi pakan dan pertumbuhan (FE; pakan/bijian) sama antara tikus yang diberi pakan E1 atau E2 dengan yang diberi CON (2,1 dan 2,2 g/hari vs. 2,2 g/hari; 4,7 dan 4,3 g/hari vs. 5,3), namun berkurang pada tikus yang diberi pakan H1 atau H2 (1,5 and 1,3 g/hari; 7,1 dan 7,0 FE) dibandingkan dengan CON. Penelitian ini menunjukkan bahwa PKC expeller berpotensi disertakan dalam pakan berbahan dasar jagung untuk babi hingga kadar 35% tanpa berpengaruh buruk terhadap pertumbuhan. Kata kunci: Asam amino, asam lemak, expeller, hidroterma
Improvement of Lamb Preweaning Performance by Combination of Superovulation of Ewes Prior to Mating and Temulawak Extract Plus Administration During Pregnancy
Get PDFAbstract. Superovulation is one of a reproductive technology to improve livestock productivity. The research was conducted to optimize the superovulation technology by combining it with administration of temulawak extract plus during pregnancy. Sixteen ewes were injected prostaglandin hormone at a dose of 10 mg/kg body weight intramuscularly twice, with eleven days interval, to synchronize estrous cycle. On the eleventh day, superovulation was induced by injection of pregnant mare serum gonadotrophin hormone at a dose of 200 IU/ewe intramuscularly. The ewes showing the estrous signs were mated naturally. Temulawak extract plus was administered weekly during pregnancy with a dose of 1 mg/kg body weight. Parameters measured in this study were lambs birth weight and preweaning growth. Superovulation increased average litter size. The result showed that, regardless of litter size, superovulation increased lambs birth weight by 15% as compared to controls and temulawak extract plus groups. Superovulation before mating and temulawak extract plus administration during pregnancy improved lambs growth in the first month and the third month postpartum. Superovulation prior to mating increased lambs birth weight and improved lambs growth performance before weaning. Keywords: superovulation, temulawak extract plus, lambs growth performance, ewes Abstrak. Superovulasi merupakan salah satu teknologi reproduksi untuk meningkatkan produktivitas ternak.
