The Effect of GnRH on Reproductive Performance and Progesterone Hormone Levels in Buffalo in West Sumatera

The administration of hormone GnRH will affect the reproductive organs and can improve the reproductive performance of buffalo. The decrease of the buffalo population is caused by various factors including genetic and environmental factors. The development of buffaloes is relatively slow because the reproduction rate of buffaloes is lower than that of cattle, besides that it is also difficult to detect estrus, the pregnancy period is relatively long and longer calving rate. This study aims to determine the best dose of GnRH on the swamp buffalo producing of dadih in Indonesia. The materials used were 16 swamp buffalo. A completely randomized design was used in this study. Buffalo is synchronized with the injection of 5 ml of GnRH hormone n on the first and 11th day, on the 10th to 12th day all donor buffaloes are injected with GnRH. Four different doses of GnRH (200, 225, 250 and 275 ml/buffalo) and each treatment was replicated five times. The speed of estrus and estrus length were the measured variables. The results showed that the doses of GnRH significantly (P<0.05) increase of estrus speed and estrus length. Progesterone levels have increased significantly starting from before treatment until after treatment with GnRH. It is concluded that the best GnRH doses for estrus synchronization in the swamp buffalo producing of dadih was 2. 25 ml/buffalo with estrus speed 18.2 h and estrus length 18 h.

Abstract The objective of this study was to estimate the effect of sire line on sow and piglet performance during lactation. Commercial Landrace x Large White females (n = 60) were bred to one of the following sire lines: a purebred Duroc line (Line S1), a synthetic (Line S2), or purebred Duroc (Line S3) from a different genetic source. Matings were balanced by line and parity. Females were fed a common gestation and lactation diet during these respective phases. Sow and piglet data were analyzed as a completely randomized design using the GLM procedure of SAS. Results show that, during lactation, females bred to line S3 lost significantly (P = 0.01) more BW (-16.93 ± 3.56 kg) than females bred to line S2 (-2.00 ± 3.50 kg). However, no evidence of a difference (P = 0.18) in BW loss was detected between females bred to line S3 (-16.93 ± 3.56 kg) vs. Line S1 (-7.90 ± 3.56 kg). Further, sows bred to line S3 weaned significantly (P = 0.03) more piglets (12.0 ± 0.28) than females bred to line S2 (10.9 ± 0.27), but not (P = 0.1) compared to females bred to line S1 (11.7 ± 0.27). No significant effect of line (P > 0.05) or parity (P > 0.05) on total number of piglet’s born, number born alive, number of stillborn piglets, or preweaning mortality was detected. The number of mummified fetus tended to be lower in line S2 (0.17 vs 0.66; P = 0.079) and line S3 (0.12 vs 0.66; P = 0.051) sows compared with line S1 sows, respectively. In conclusion, sire line did not have a significant effect on total number born, number born alive, number stillborn, or preweaning mortality. However, females bred to line S3 lost significantly more BW during lact but weaned significantly more piglets than females bred to line S2.

Abstract Previous research demonstrates grazing tall fescue can decrease reproductive performance and weight gain in cattle. The objective of this study was to evaluate Fescue EMTTM Mineral Defense (Cargill Animal Nutrition, Minneapolis, MN) on summer weight gain in cattle grazing tall fescue pastures in SW Missouri. Heifers (n = 120; initial BW = 236 ± 2.5 kg) were stratified by weight to replicated tall fescue pastures to either a control mineral treatment or Fescue EMT™ Mineral Defense treatment. Forage availability was estimated weekly by ultrasonic sensor. Pasture samples were collected every 21 d and analyzed for ergovaline concentrations. Heifer weights and blood prolactin were measured throughout the trial. Average daily mineral consumption was calculated by mineral offered less residual. Data were analyzed on a pen-mean basis as a completely randomized design using JMP with 6 pens/ treatment and 10 heifers/pen. Prolactin was analyzed as Repeated Measures in JMP. Initial weights between treatments were not different (P > 0.05). Endophyte infection measured 75% or greater in all pastures. No differences were detected in pasture ergovaline (149 ± 19 µg/kg) or pasture availability (2,600 ± 150 kg/ha) between treatments (P > 0.20 at each sampling). Heifer ADG consuming Fescue EMT™ Mineral Defense compared to control mineral was greater at 0.28 kg versus 0.22 kg resulting in total gains of 21.8 kg versus 16.6 kg, respectively (P < 0.05). However, blood prolactin numerically decreased over time in both treatments. Results from this trial demonstrate a 31% improvement in weight gain for cattle consuming Fescue EMTTM Mineral Defense compared with cattle consuming a control mineral while grazing toxic tall fescue.

The G2 trangsenic Mutiara catfish (Clarias sp.) (MTG) is a Mutiara catfish that is inserted with the CgGH gene (Clarias gariepinus Growth Hormone) through the transgenesis. The effect of transgenesis stimulates gonad growth of G2 transgenic Mutiara catfish (Clarias sp.) faster than non-transgenic fish. Study aimed to analyze the maturity of the gonads and the spawning ability of female G2 transgenic Mutiara catfish (Clarias sp.) to obtain superior broodstock candidates. Experimental method with completely randomized design (pair of parents used as treatment and repeated four times) for spawning was used for this study. Three pairs of parent G2 were crossed semi-artificially as treatment A (female 1 MTG G2 crossed with male 1 MTG G2), B (female 2 MTG G2 crossed with male 2 MTG G2) and C (female 3 MTG G2 crossed with male 3 MTG G2). The results showed that the performance of female G2 transgenic Mutiara catfish (Clarias sp.) (treatment A, B and C) was higher given non-transgenic with an average relative fecundity of 82,438 eggs / kg of broodstock, an average egg diameter of 1.76 mm and an average egg weight 1.75 mg. These indications suggest that GH transgenesis increases gonadal maturity. The gonad maturity profile reached the stage of complete maturity (full ripe) compared to Sangkuriang catfish (Clarias gariepinus) (immature gonads). Therefore it is necessary to compare the reproductive performance of G2 transgenic Mutiara catfish (Clarias sp.) with non-transgenic fish (Sangkuriang) as candidates for superior broodstock of catfish.

An experiment was conducted with 24 buck and 24 doe rabbits of about 5-8 months. The animals were fed diets containing garlic flour meal to determine the effect on the hormonal profile and reproductive performance of the rabbits. The 48 rabbits were separated according to their sexes (buck and doe) and divided into four treatment groups with four rabbits consequently replicated three times in a completely randomized design. Dietary levels of 0.0, 5.0, 10.0 and 15.0% of garlic flour meal were used to formulate the diet for rabbits. At the end of this trial, different parameters on hormonal profile and reproductive performance were determined. All the parameters of hormonal profile were significantly P<0.05) different thereby maintaining similar values except luteinizing hormone which had slight value fluctuation. The highest value of testosterone and progesterone were recorded in the diet containing 15.0% garlic flour meal. Similarly, the parameters on reproductive performance exhibited significant (P<0.05) difference. Partum weight and litter weight at birth showed a higher value as garlic meal was increased. The results of this study indicated that 15.0% dietary level of garlic flour meal proved acceptable for hormonal profile and reproductive performance of rabbit.

Antibiotic Growth Promoter (AGP) synthetic as a feed additive can stimulate growth, prevent some health problems, and improve feed efficiency. However, its journey has raised concerns due to adverse effects such as residues and microbial resistance. The use of turmeric flour and betaine as feed additives is expected to substitute the use of AGP Synthetic in improving the performance of pig carcasses and the safety of consumption. This study was aimed to examine the effect of the addition of turmeric flour and different doses of betaine in the ration on the performance of finisher period pigs. The study was conducted experimentally using a completely randomized design with four treatments and five replications. The objects of the study were 20 male and female finisher Landrace pigs with a finisher period with initial body weights of 55-66 kg/head. The study rations used were R0: basal ration, R1: R0 + 0.4% turmeric flour + 0.1% betaine, R2: R0 + 0.4% turmeric flour + 0.15% betaine and R3: R0 + 0.4% turmeric flour + 0.2% betaine. The parameters measured were carcass weight, backfat thickness, and loin eye area. The addition of turmeric flour treatment did not have any significant effects on carcass weight and thickness of the back fat of the pig. The addition of 0.4% turmeric flour and 0.15% betaine in the ration was the best treatment and resulted in a different effect on the loin eye area compared to that of R0, while treatment R1 and R3 had a similar effect on it. The result of the addition of 0.4% turmeric flour and 0.15% betaine resulted in the loin eye area of the finisher pig of 53.4 cm2
