Abstract

The objective was to assess the behavioral indicators of cattle housed in different shade surface availabilities under dry tropical environmental conditions carried out in the summer-autumn period. During 63 days the usual social and agonist variables were recorded in 1,040 bulls housed in 16 pens (4 replicas/treatment, 65 bulls/pen). Ambient temperature (AT) and relative humidity (RH) were record-ed, and the humidity index (THI) was estimated. The shade surfaces tested were 1) conventional shade (S12%), 2) double shade (S24%), 3) shaded 100% without fans (S100), and 4) shaded 100% with fans (S100F). The average maximum value for AT, RH and THI was 38.1°C, 90.7% and 87.6 units. The shade surface influenced the proportion of animals under shade, eating, ruminating, and mounting, and decreased the proportion of animals panting. Pens S24 showed a higher proportion of animals eating and resting (quadratic component, P=0.05). Providing ventilation increased (P=0.01) 2.7 times the pro-portion of animals eating and decreased (P=0.01) 6.5 times the proportion of animals panting. At 0800h a greater proportion of animals eating and riding was observed, while from 1130h onwards the proportion of animals under shade, ruminating and resting increased. At 2:00 p.m., the highest percent-age of animals were panting. It is concluded that  a shaded surface of 12% of the pen area is enough to alleviate behavioral patterns in animals under high environmental heat load. Shade plus ventilation was shown to be a strategy in reducing panting and increasing the proportion of animals in feed bunks.

Abstract

Genetic parameters for egg production traits in the KU-Phuphan black bone chicken, a native Thai breed, were analyzed to estimate heritability, investigate genetic correlations, and provide essential genetic data for developing effective breeding strategies to improve egg production performance. The study focused on traits age at first egg (AFE) and cumulative egg production at 180, 270, 300, and 365 days. Data were collected from 541 hens across three generations raised in an open-house system. Ge-netic parameters, including heritability and genetic correlations, were estimated using the AIREMLF90 software with the average information restricted maximum likelihood method. The results revealed moderate heritability for AFE (0.41) and higher heritability estimates for cumulative egg production traits (0.30–0.50). Genetic correlations among egg production traits were high (0.93–0.99), indicating that these traits were influenced by similar genetic factors. However, the genetic correlations between AFE and egg production traits were low (0.18 to -0.02), suggesting that these traits were influenced by different genetic factors. In conclusion, the potential was highlighted for genetic selection to improve egg production traits in this breed. Therefore, in designing breeding programs, breeders should consid-er the high heritability of egg production traits and the low genetic correlations between AFE and egg production.
Bioprospecting snakehead fish protein concentrate (SFC) as a non non-serumserum-based albumin source for promoting capacitation in bovine sperm Setiawan, H.; Lertwichaikul, T.; Thongkham, M.; Chuammitri, P.; Sringarm, K.; Intanon, M.; Sathanawongs, A.

Abstract

Capacitation is a prerequisite for successful fertilization with albumin as an inevitable component among the oviductal fluid's constituents. Under in vitroenvironments, albumin's function is replaced by serum-based products, which carry the issue of unsustainability, some allergies, and potential trans-mission of transmissible spongiform encephalopathies (TSEs) to the unborn fetus. To discover an alter-native, sustainable, and innoxious promoter, snakehead fish (Channa striata) albumin was examined for its potential to promote capacitation in bovine sperm. Snakehead fish protein concentrate (SFC) with respective albumin concentrations of 3, 6, and 9 mg/mL was added to the bovine capacitation me-dium. Following the swim-up technique, bovine sperm were incubated in different treatment groups for 90 minutes to stimulate the capacitation process. The results revealed that the application of 3 mg/mL albumin from SFC in Tyrode's-based capacitation medium (T-SFC3) provided sufficient evidence in promoting capacitation, as demonstrated by higher sperm exhibiting hyperactive motility, kinematic parameters, and the percentage of sperm showing B pattern as compared to Tyrode's-based capacitation medium containing 6 mg/mL BSA (T-BSA6) (p>0.05) and other levels of T-SFCs (p<0.05). In con-trast, greater concentrations of SFC application retrieved more viable sperm with intact acrosomes and less in both viable and mortal sperm with reactive acrosomes (p<0.05).

Abstract

This study aimed to evaluate the effects of adding basil (Ocimum basilicum L.) leaf meal waste to feed on stress indicators, immune responses, and performance of growing quails (Coturnix coturnix japonica). Two hundred female quails 3-week-old were allocated in a completely randomized design with four treatments: 0% (P0), 1.5% (P1), 3% (P2), and 4.5% (P3), each with five replicates of 10 birds. The Observed variables included oxygen saturation, heterophil/lymphocyte ratio, hepatic superoxide dismutase (SOD) activity and malondialdehyde (MDA) level, leukocyte profiles, and clearance ability against Salmonella pullorum. Growth performance was measured through feed intake, body weight gain, and feed conversion ratio. Results showed that 3% basil leaf meal waste improved oxygen saturation and SOD activity, reduced H/L ratio and MDA level, and produced the highest bacterial killing ability. The best growth performance and most efficient feed conversion were also observed in P2. It can be concluded that 3% inclusion effectively reduces oxidative stress, enhances immunity, and improves quail performance.
