To confirm it, the aim of this in vitro study was to determine the effective dosage of kemuning leaves from two extraction methods (infuse and maceration) to reduce the Trichostrongylidae and to evaluate the bioactive compounds of the leaves. The research was conducted using a randomized complete design with 11 treatments and 5 replications. The treatments consisted of control (0.0005% and 0.005% Oxfendazole), kemuning leaves infuse extract (KIE) and maceration extract (KME) each with level of 1%, 3%, 5%, and 7% (w/v). The results showed that the LT50 gradually decreased (shortening the lethal time) and the mortality of Trichostrongylidae gradually increased associated with the increased concentration of treatment (P<0.01). The infusion of 7% kemuning extract demonstrated the highest efficiency in reducing the larval development, infective larvae, and the adult Trichostrongylidae by 93.16%, 94.39%, and 90%, respectively.

Phenotypic characterization was used to identify and document the diversity within and between distinct breeds, based on their observable attributes. Phenotypic characterization and body biometric in 23 traits were measured in 191 purebred horses belonging to three breeds, i.e. Turkoman (70 horses), Kurdish (77 horses), and Caspian (44 horses). Caspian breed was sampled from the Provinces of Alborz and Gilan. Kurdish breed was sampled from the Provinces of Kurdistan, Kermanshah, and Hamadan. Turkoman breed was sampled from the Provinces of Golestan, Markazi, and Isfahan. Multivariate analysis of variance (MANOVA) was implemented. In addition, Canonical Discriminate Analysis (CDA), Principal Component Analysis (PCA), and Custer analysis were executed for assessing the relationship among the breeds. All statistical analysis was executed by SAS statistical program. The results of our investigation represented the breeds classification into 3 different classes (Caspian, Turkoman, and Kurdish) based on different morphometrical traits. Caspian breed with smaller size in most variables was detached clearly from the others with more distance than Kurdish and Turkoman breeds. The result showed that the most variably trait for classification was Hind Hoof Length. Adaptation with different environments causes difference in morphology and difference among breeds. We can identify and classify domestic population using PCA, CDA, and cluster analysis.","PeriodicalId":18346,"journal":{"name":"Media Peternakan","volume":"39 1","pages":"155-160"},"PeriodicalIF":0.0,"publicationDate":"2016-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"70659679","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The chicken stocking condition needs more attention as a part of animal welfare. This study was performed to identify the relationship between the stocking density and the stress based on Temperature Humidity Index (THI) and the effect of stocking density on meat quality, i.e., physical, microbiological, and organoleptic. Ninety DOCs of Kampong-Broiler (KB) were assigned into a completely randomized design with 3 treatments of stocking density i.e., 8, 10, and 12 birds m-2. Each treatment was replicated 3 times. The experimental chickens were housed in 9 blocks of housing each with 1 x 1 m2 size. Data on physical and microbiology of meat qualities were analyzed with analysis of variance and continued with Duncan’s multiple range test. The organoleptic data were analyzed by using Kruskal-Wallis test. The result showed that the stocking density did not significantly affect the physical and hedonic quality of KB chicken’s breast. The stocking densities significantly affected (P<0.05) the microbiological variables of breast meat. The average value of THI during maintenance reached 28.98±1.25–29.33±1.32oC. The higher the animal density the higher the THI value that correlated to the stress condition. However, high stocking density did not affect the physical and hedonic quality of breast meat, thus it can be accepted by the consumers. The higher the stocking density the higher the total plate count, Escherichia coli, and Staphylococcus aureus, without the presence of Salmonella sp.

A total of 275 Holstein heifers housed in a free barn were used for the experiment.

A group of four to 14 animals, depending on the availability, were referred to the experiment at each visit. Estrus induction rates in the two protocols were 93.9% and 94.9%, respectively. There was no difference in the conception rate between the two protocols. Conception rate after artificial insemination (AI) or embryo transfer (ET) were 46.3% and 51.4%, respectively. The risk factors affecting conception rate in heifers were daily weight gain (odds ratio [OR]= 4.673; P= 0.036) and body condition score (BCS) (OR= 3.642; P= 0.018). Furthermore, estrus synchronization protocol (OR= 1.774; P= 0.083) and the absence of corpus luteum (CL) at the initiation of treatment (OR= 0.512; P= 0.061) had a tendency to affect the conception rate, while age (OR= 0.715; P= 0.008) was a protective factor to conception rate.

The samples were subsequently evaluated for their fermentation characteristics and digestibility by using a two-stage in vitro rumen fermentation technique, maintained at 39 oC for 2 × 48 h. The in vitro incubation was performed in three consecutive runs by following a randomized complete block design in which each sample per run was represented by four fermentation tubes. Results revealed that all experimental beans contained high crude protein (CP), i.e. above 200 g/kg dry matter (DM), but only soybean and groundnut had CP contents higher than 300 g/kg DM. Redbean had the lowest crude fiber and acid detergent fiber contents among the beans. Soybean contained high proportion of rapidly degraded CP fraction, but low in slowly degraded and unavailable CP fractions. High proportion of slowly degraded CP fraction was found in redbean and bambarabean. Redbean, pigeonpea, cowpea, and mungbean were better than soybean, groundnut, and bambarabean with regard to DM degradability and DM digestibility values (P<0.05).

A total of 135 kampung chicken fertile eggs (weight 42-43 g) were used and divided into 5 treatment groups of three replications. They were placed in the semi-automatic incubator. The first group was without in-ovo feeding (negative control); the second group was in-ovo feeding of saline 0.9% (positive control); the 3, 4, and 5 groups were in-ovo feeding of 0.5, 1.0, and 1.5% L-Arginine, respectively.

The results showed that in-ovo feeding of L-Arginine increased weight and circumference of the embryo, but did not affect the length of embryo. In-ovo feeding of L-Arginine resulted in a higher body weight gain and a lower feed conversion even though feed intake was not significantly different compared to the control groups. The growth rate performance up to 6 weeks rearing increased significantly by increasing L-Arginine administration to 1.0%.

The objective of this study was, therefore, to evaluate in vitro digestibility, ruminal fermentation characteristics, total gas and methane production through the meta-analysis approach. Meta-analysis was applied to 13 experiments and 42 treatments dealing with glycerol supplementation in ruminants. Data were analyzed by general linear model procedure in which the glycerol levels and the different studies were treated as fixed effects. Results revealed that glycerol supplementation did not affect the in vitro digestibility and total VFA production, but significantly decreased molar proportion of acetate and iso-valerate (P<0.05). In contrast, molar proportion of propionate, butyrate, and valerate significantly increased, and thus the ratio of acetate to propionate declined linearly (P<0.05). Methane production decreased linearly and accompanied with an increase of total gas production with increasing levels of glycerol supplementation (P<0.05).
