Effects Of Full-Fat Soybean Diet On Performance, Carcass Characteristics,And Fatty Acid Composition Of Hanwoo Steers, Sungil Kim, Jihong Lee, Sungkwon Park
Turkish Journal of Veterinary & Animal Sciences
The effect of dietary full-fat soybean on performance and carcass characteristics of Hanwoo steers was investigated. Thirty steers (653 ± 52.96 kg) were allotted to control and full-fat soybean groups with a 210-day comparative feedlot trial. Steers were fed either the basal finishing diet (control) or control plus 5% full-fat soybean, using Calan gates for individual intake measurement. There was no difference in BW, feed intake, carcass weight, backfat thickness, loin muscle area, or meat color between groups. The average daily gain was greater (P < 0.05) in the soybean group compared to the control group. Steers fed soybean showed a lower feed conversion ratio than the controls. Marbling in the soybean group was greater (P < 0.05) than that in the control group. Supplementary full-fat soybean increased (P < 0.05) crude fat but decreased (P < 0.05) crude protein content in the longissimus muscle. Full-fat soybean increased (P < 0.05) total unsaturated fatty acids, including the levels of oleic, linoleic, and linolenic acid but, consequently, decreased (P < 0.05) total saturated fatty acids. Levels of conjugated linoleic acid, and its major precursor trans-vaccenic acid, were significantly increased by soybean supplementation. Our results demonstrate that full-fat soybeans may offer a better way to produce healthier beef with increased unsaturated fatty acids.

Poor Placental Traits Reduce Kid Birth Weight In Young Saanen Dams In The First Parity, Uğur Şen, Hasan Önder
Turkish Journal of Veterinary & Animal Sciences
Placental characteristics are the most important indicators of fetal growth and development that influence kid vitality. The aim of this study was to examine the effect of maternal parity on placental characteristics and birth-related traits in Saanen goats. The experiments were conducted on 41 singleton-bearing Saanen does, ranging from 1 to 4 years of age and classified according to first, second, and third parities. Birth weight, placental weight, placental efficiency, and cotyledon density were influenced by parity (P < 0.05). First-parity does had kids with significantly (P < 0.05) lower birth and placental weights than does of other parities, while they had significantly higher (P < 0.05) placental efficiency and cotyledon density. First-parity does had fewer (P < 0.05) large and total cotyledons than third-parity does. Cotyledon dimensions varied among parities (P < 0.05), while average cotyledon surface area and cotyledon efficiency were the lowest in the first-parity does (P < 0.05). The results suggest that younger dams in the first parity may alter placental characteristics and fetal development, resulting in a reduced birth weight from singleton gestations.

Foetal growth and haemodynamic features were investigated in singleton and twin pregnancies in Karya ewes with B-mode/Doppler ultrasonography. Nineteen healthy singleton (n = 9) and twin (n = 10) pregnant Karya ewes were used. Foetal biometric and haemodynamic measurements were made at 15-day intervals on the 29 foetuses during pregnancy. Biparietal head diameter (BPD), thoracic diameter (TD), umbilical cord diameter (UCD), foetal heart rate (FHR), peak systolic velocity (PSV), end diastolic velocity (EDV), pulsatility index (PI), and resistance index (RI) were recorded. The BPD was higher in twins on days 55 and 130 of pregnancy (P < 0.05), and the TD was higher in singletons on day 115 of pregnancy (P < 0.01). UCD was higher in twins on day 55 of pregnancy (P < 0.01). On day 130 of pregnancy, PSV and EDV were higher in twin foetuses (P < 0.05). PI and RI were lower in twins on day 40 of pregnancy (P < 0.05). Foetal growth and umbilical artery blood flow show some differences depending on the numbers of foetuses and the gestational stage. Additionally, BPD, TD, and FHR were reliable for estimation of gestational age during twin pregnancies.

Twenty-one Holstein bull calves (368 ± 5.2 kg) were used in order to evaluate the effects of combining recombinant bovine growth hormone (bST) and anabolic implants on growth performance and dietary energetics. Steers were assigned (7 repetitions/treatment) to individual pens (16 m2) equipped with automatic waterers and 1.2 m fence-line feed bunks. The experiment lasted 56 days. Treatments were: 1) no bST, no implant; 2) implant; and 3) bST + implant. Compared to implanted cattle, the combination of exogenous bovine somatotropin and anabolic implants did not enhance growth performance or observed dietary energy. Compared to nonimplanted cattle, anabolic implants increased …

In this study, we aimed to investigate the efficacy of a commercial ELISA test kit for detecting pregnancy-associated glycoproteins (PAGs) in peripheral blood for early pregnancy diagnosis and compare plasma PAG levels during early pregnancy in both Holstein-Friesian heifers and lactating cows. A total of 231 plasma samples were collected from heifers and lactating cows on days 25, 28, and 32 after insemination. Pregnancies were confirmed 30 days after the collection of plasma samples. Plasma PAG levels were measured using a commercial ELISA test kit for diagnosing bovine pregnancy. The effects of examination date and animal status (heifers vs. lactating …
