Carcass characteristics, meat quality, sensory palatability and chemical composition of Thai native cattle grazing in lowland and Phu Phan mountain forest.

Objective: The aim of this study was to assess the effect of Thai native cattle grazing in the lowland or mountain forest on carcass characteristics, meat quality, sensory palatability, and chemical composition.

Methods: Twelve male Thai native cattle with an average weight of 110±10 kg are allowed to be grazing in the lowland or Phu Phan mountain forest during the rainy season in northeastern Thailand.

Results: The carcass characteristics, meat pH, and meat color were unaffected by treatment (p>0.

Effect of Dietary Supplementation of Hydrolyzed Yeast on Growth Performance, Digestibility, Rumen Fermentation, and Hematology in Growing Beef Cattle.

This experiment was conducted to assess the effect of hydrolyzed yeast (HY) on growth performance, nutrient digestibility, rumen fermentation, and hematology in growing crossbred Bos indicus cattle. Twenty crossbred beef cattle with an initial body weight (BW) of 142 ± 12 kg were randomly assigned to one of four treatments for 90 d in a randomized complete block design (RCBD) having five blocks based on a homogenous subpopulation of sex and BW. Cattle were fed with a total mixed ration (TMR) and supplemented with HY at 0, 1, 2, and 3 g/kg dry matter (DM), respectively.

Fermented Rubber Seed Kernel with Yeast in the Diets of Tropical Lactating Dairy Cows: Effects on Feed Intake, Hematology, Microbial Protein Synthesis, Milk Yield and Milk Composition.

The objective of the present study was to analyze the effects of yeast-fermented rubber seed kernels (YERSEK) on the feed intake, hematology, microbial protein synthesis, milk yield, and milk composition in dairy cows. Six crossbred Holstein Friesian (HF) × Thai lactating dairy cows with 110 ± 10 days in milk were randomly assigned to three different amounts of YERSEK at 0%, 10%, and 20% in a concentrate mixture using a 3 × 3 repeated Latin square design. Cows were fed with concentrate diets at a concentrate-to-milk yield ratio of 1:1.

Improving ensiling characteristics by adding lactic acid bacteria modifies in vitro digestibility and methane production of forage-sorghum mixture silage.

Improving the nutrition of livestock is an important aspect of global food production sustainability. This study verified whether lactic acid bacteria (LAB) inoculant could promote ensiling characteristics, nutritive value, and in vitro enteric methane (CH) mitigation of forage sorghum (FS) mixture silage in attacking malnutrition in Zebu beef cattle. The FS at the soft dough stage, Cavalcade hay (CH), and cassava chip (CC) were obtained.

The onset of puberty in indigenous male Thai pigs.

Knowledge of puberty plays an important role in planning livestock breeding. The objective of this study was to evaluate the age of the first sexual behavior and the first fertile sperm production, and the changes of reproductive structures in male Thai indigenous pigs, by using a completely randomized design. Male indigenous piglets were randomly divided into 9 groups; each group of 5 piglets was separately sacrificed at the age of 0 (birth), 1.

Effects of cytoplasts from Taiwan native yellow cattle on the cellular antioxidant ability of cloned Holstein cattle and their offspring.

We previously demonstrated that the cellular thermotolerance of cloned cattle produced by combination of ooplasm (o) derived from Taiwan native yellow cattle (Y) and the donor (d) nucleus derived from Holstein (H) cattle (Yo-Hd) transmits to their offspring (Yo-Hd-F1). In the present study, the responses of mitochondria in these cloned cattle and their offspring after heat shock were investigated to elucidate influence of cytoplasmic input (i.e.

Ear fibroblasts derived from Taiwan yellow cattle are more heat resistant than those from Holstein cattle.

The objective of this study was to compare the thermotolerances of ear fibroblasts derived from Holstein (H) and Taiwan yellow cattle (Y) and their apoptosis-related protein expressions with (1, 3, 6, 12, and 24h) or without heat shock treatment. The results showed that the vaginal temperatures of Y (38.4-38.

Cellular thermotolerance is inheritable from Holstein cattle cloned with ooplasts of Taiwan native yellow cattle.

We have previously demonstrated that the somatic cells from cattle cloned with Holstein (H) donor cells and Taiwan native yellow cattle (Y) ooplasm (Yo-Hd) had better thermotolerance than those from cattle cloned with both Holstein donor cells and ooplasm (Ho-Hd). The present study aimed to investigate whether the cellular thermotolerance of these cloned cattle is transmissible to their offspring (Ho-Hd-F1 and Yo-Hd-F1). Thermotolerance of ear fibroblasts derived from these cloned cattle and their offspring were analyzed.
