Abstract

This study aims to determined the effect of watermelon's inner rind extract (Citrullus lanatus) towards the integrity of the plasma membrane and morphological abnormalities of male Norway rats's spermatozoa (Rattus norvegicus) after being exposed to hot temperature. The content of lycopene in the inner rind of watermelon serves an antioxidant counteracting free radicals. A total of 20 male Norway rats (Rattus norvegicus) were used in this study with an average age of 2 months. The study was divided into five treatments and four replications, consisting of: K(-) as negative control given CMC Na 0.5% as much as 0.5 ml, P0 as positive control was exposed to 40° C for 1 hour and CMC Na 0.5% of 0.5 ml. P1, P2 and P3 are exposed to 40° C for 1 hour and inner rind extracts of  watermelon with a multilevel dose of P1: 20mg/head/day, P2: 40mg/head/day, and P3: 80mg/head/day that each dose was dissolved in CMC Na 0.5% of 0.5 ml. The results showed that giving inner rind extract of  watermelon to the rats increased the integrity of the plasma membrane and decreased morphological abnormalities of male rat's spermatozoa (Rattus norvegicus). The result of increased the integrity of the plasma membrane and highest decreased morphological abnormality was shown by P3 group given a dose of 80 mg/head/day.

Abstract

Repeat breeding is a reproductive disorder that harms dairy farmers because of the unachieved target to obtain one calf per year and decreased milk production. The repeat breeding syndrome can be caused by malnutrition. This study aimed to determine the effect of feeding silage, complete feed, and growth promoters in repeat breeder cows to restore the services per conception (S/C) and daily milk production. Thirty repeat breeder Holstein Friesian cows were divided randomly into three groups. The control group (P0) was fed 30-40 kg forage and 3-4 kg concentrate/head/day. Group P1 was given 8-10 kg silage or complete feed alternately every day; whereas P2 was given the same as for the P1 group, added with 10 ml growth promoter/head/day. Milk production and S/C were measured after six months of treatment. The results showed that the P1 and P2 groups returned S/C to normal (1.40 ± 0.52 and 1.30 ± 0.48), while the S/C of P0 group was 3.20 ± 0.63 (p <0.05). Daily milk production in the P1 and P2 groups (14.20 ± 1.40 and 14.60 ± 1.43 l/d) was also higher (p <0.05) than the control group (8.30 ± 1.06 l/d). It could be concluded that feeding silage and complete feeds alternately daily, with or without the addition of growth promoter, improved the S/C to the normal range and increased milk production.
