The first was kept in an additive-free environment, and the second added 1 g of Bio-C plus to every liter of drinking water for the doe rabbits. The findings demonstrated that pregnant rabbits subjected to extreme heat stress during the hot summer months experienced a considerable loss in body weight and feed intake and a considerable drop in conception rate.

This research aims to analyze the genomic population structure of Santa Inês sheep managed on different properties in northeastern Brazil. A total of 390 individuals were genotyped for 52,744 SNPs. The six flocks evaluated showed population differentiation indices (pairwise Fst) ranging from 0.0342 to 0.0938. Estimates of gene flow showed high values, ranging from 0.89 to 1 (Nm) between flocks 2 and 3, which are from the same town. The average value for inbreeding (Fis) and the overall genetic differentiation index (Fst) were -0.05 and 0.06 respectively, observed in the F statistic for each of the loci analyzed in the six flocks. These results indicate that diversity is concentrated within populations. After the simulations using the Bayesian clustering method, the most probable number of genetic groups (K) detected was 5, where flock 4 and 6 form a single group. It can be concluded that the samples from the six flocks form five genetic populations with a level of diversity that has been conserved.

The use of integrated pest management approaches has since been advocated in contemporary research to sustainably control fly populations. Recent studies have found garlic (Allium Sativum) and its derivative bioactive compounds to possess insect-repellent attributes among other key health and production enhancing properties. This highlights the potential of garlic as a botanical pesticide to control flies in cattle. Moreover, the ability of cattle to naturally repel flies is influenced by animal genetic predisposition. The dietary garlic supplementation and gene interaction in disease resistance could also be an influential factor in repelling flies in cattle. Transcriptomics has emerged as a valuable tool in animal breeding and genetics which allows identification of trait-associated genes and understanding of complex interactions between dietary nutrients and animal genome expression. This paper explores the nutrigenomic effects of garlic supplementation on cattle and its contribution towards fly repellence efficacy in cattle. It was concluded that garlic supplementation in cattle diets could offer a sustainable approach to managing fly infestations in cattle farming.

Sixty-two percent (62%) of the farmers vaccinated their chickens against common poultry diseases. The average mortality rate was 7%, being caused by diseases (99%) and unknown (1%). Bio-security was achieved through cleaning, disinfection and restricted entry. The most preffered age at sale was 18-24 weeks. An informal market system was mainly used (95%) and the average selling price per bird was $8 (ranging from $6-$11).

Twenty-four Friesian male calves at 4 days of age with a similar genetic line, weighing 33.67 ± 0.6 kg, were randomly allocated to three groups (8 animals per group). The study comprised three groups: a control group (NS0) receiving no supplementation, and two experimental groups received either 1% (NS1) or 3% (NS3) NS supplementation for 84 days. All levels of NS supplementation significantly improved the final body weight and body weight gain in a linear manner (P < 0.001), while the highest total dry matter intake was observed in NS1 group (quadratic; P < 0.001). White blood cells (quadratic, P = 0.026), lymphocytes (quadratic, P = 0.012), and monocytes (linear effect; P = 0.001) significantly decreased, whereas red blood cells (linear; P = 0.004), hematocrit (linear; P = 0.002), mean corpuscular volume (MCV, linear; P = 0.003), and mean corpuscular hemoglobin concentration (MCHC, quadratic, P = 0.007), platelets (linear; P < 0.001) increased in calves fed NS. Feeding calves diets supplemented with NS led to a significant linear decrease in plasma creatinine and liver enzymes (AST and ALT) compared to the control diet (P < 0.01). Calves fed 3% of NS in their diets had lower plasma cholesterol (linear; P < 0.001) and triglyceride levels (linear; P = 0.002) compared to calves in NS0 and NS1 groups.
