Abstract

Livestock is one of the agricultural sectors that plays an important role in providing animal products. Cows are one of the largest meat and dairy producers. The low reproductive efficiency of cattle is the biggest problem in terms of its development. Increasing reproductive efficiency through artificial insemination programs is one way to enhance livestock populations. Reproductive efficiency parameters can be measured through values of Service per Conception (S/C) and Conception Rate (CR). Service per conception and conception rate are related to cows parity. Parity is the number of calf that have been born to a cow. This study aimed to provide information on reproductive efficiency as seen from the value of S/C and CR of cows in different parieties and the factors that influence them. High rates of parity followed by high S/C score and low CR. Each animal has various values of S/C and CR. The normal range for S/C is 1.6-2.0 and 60% in CR. Several factors that affect reproductive efficiency are environment, nutrition, Body Condition Score (BCS), knowledge of farmers, inseminator skills and quality of semen used. The highest service per conception (S/C) value was at parity 5 with aged ± 7 years and the conception rate (CR) was at parity 3 aged ± 5 years.Keywords: should be written in no more than 5 (five) words or phrases.

Abstract

Soft cheese Suspesi is a soft cheese to which biduri leaf extract is added as a coagulant. There is no research on the color, hardness, and content of tannins contained in soft cheese suspesi. The purpose of this research was to analyze and evaluate the hardness, color *L, *a, *b, and tannin content with the addition of biduri leaf extract at levels of 3% and 5% in soft cheese suspesi. This research used a completely randomized design with two treatments with six replications. A1= Biduri leaf extract level 3% (v/v), A2= Biduri leaf extract level 5% (v/v). Data on hardness, color, and tannin content were analyzed by Independent T-Test. The results showed a significant difference (P<0.05) in the hardness, color *L, and tannin content. Color *a and color *b did not show a significant difference (P>0.05). In conclusion, the levels of added biduri leaf extract gave different levels of hardness, color *L, *a, *b, and tannin content in the soft cheese suspesi. The characteristics of the soft cheese suspesi increased in terms of hardness, color *L, *a, *b, and tannin content in line with the level of added biduri leaf extract.

Abstract

Aflatoxin M1 (AFM1) is the main secondary metabolites of aflatoxin B1 (AFB1) framed in the liver and discharged into milk when people and animals polish off AFB1-polluted food. The persist from feed to milk in dairy cows is affected by different dietary and physiological elements, including taking care of regimens, rate of ingestion, rate of absorption, animal health, hepatic biotransformation limit, and real milk production of the animals. AFM1 exposure might cause both intense and constant toxicity. In humans, AFM1 exposure is related with cancer-causing nature, genotoxicity, mutagenicity, and teratogenicity. In dairy animals, persistent openness to AFs can decrease execution, debilitate liver capability, compromise invulnerable capability, and increment sickness susceptibility. AFM1 openness represents a worry for the worldwide populace, especially for babies and youngsters who drink milk in bounteous amounts and thus, are more powerless to unfavorable impacts. The identification and quantification of AFs represents a critical test in food handling confirmation, since even a low AF concentration is hazardous for people and domesticated animals. Consistent human openness through dietary courses has prompted the burden of most extreme cut off points for AFM1 in milk and dairy products, taking into account that this is a gathering of products with exorbitant premium, particularly for babies and youngsters. Likewise, as per different examinations it is additionally very much felt that youthful animals are additionally observed to be more vulnerable to aflatoxin than grown-ups. Consequently; the defilement of cow milk and milk products by AFM1 ought to be perceived as unfortunate for youthful human and animals. Thus, the point of this paper is to review the occurrence of aflatoxin and its adverse results on animals and human health over the time.
