Summary: The study investigated the effect of dam breed on the growth and carcass characteristics of beef-cross-dairy-breed progeny. Results showed that dam breed had a significant impact on the growth traits and carcass characteristics of the calves, with an increase in Jersey genetics resulting in slower growth, lighter carcass, and yellower fat.

Summary: The study aims to estimate breed and heterotic effects for mature weight (MWT) in crossbred cows. By analyzing weight-age data of 5,156 crossbred cows, significant direct heterosis effects on MWT and maternal heterosis effects on the growth rate k were observed. The findings suggest that incorporating MWT in cattle breed selection can impact overall profitability, with the Angus breed being heaviest at maturity.

Summary: This study aimed to estimate variance components related to imprinting for carcass traits and physiochemical characteristics in Japanese Black cattle. It found that imprinting variances were mainly due to the maternal contribution, indicating the existence of maternally expressed genomic imprinting effects on the traits in Japanese Black cattle. Therefore, maternal gametic effects should be considered in breeding programs.

Summary: This study conducted a meta-analysis to evaluate the impact of distillers' grains (DG) supplementation on the performance, carcass parameters, and meat fatty acid profile of beef cattle. The results showed that DG inclusion had a significant effect on meat fatty acid profile, especially in crossbreed animals. For Angus animals, the effect on meat fatty acid profile was minimal, but a notable reduction in omega-6/omega-3 ratio was observed. Within certain limits, the addition of DG had no adverse effects on performance, carcass parameters, and meat physicochemical characteristics. Optimal results in terms of carcass parameters and meat fatty acid profile were obtained with DG inclusion levels between 500 and 600 g/kg. Animals fed diets containing DG had increased CLA c9 t11, linolenic acid, and total PUFA concentrations, while myristic acid concentration was reduced in the meat.

Summary: The objective of this study was to evaluate the effects of different combinations of monensin and narasin on finishing cattle. The study found that the narasin group had higher feed intake during the feeding period compared to the monensin group, but these additives did not affect the digestibility of nutrients, growth performance, or carcass characteristics of the cattle.

Summary: The impact of moderate heat load on plasma hormone concentrations in cattle was studied, comparing thermally challenged (TC) feedlot steers to feed restricted thermoneutral (FRTN) steers. Differences in plasma leptin, adiponectin, and T4 between the two groups were observed during the challenge and recovery periods, as well as occasionally during the outdoor pen period. Relationships between plasma hormone concentrations, rumen temperature, and dry matter intake were also investigated.

Summary: This study developed a statistical model to predict the carcass weight (CW) of grass-fed beef cattle at different stages before slaughter using historical cattle data. The results showed that the CW of the cattle was strongly associated with the animal's body weight at each stage before slaughter. The outcomes of this study demonstrate the value of using historical data in optimizing production and improving efficiency in the supply chain.

Summary: This review discusses the physiological and biochemical connections between steroidal implants and zinc, as well as their interaction on growth in beef cattle. Zinc is essential for skeletal muscle growth, and strategic supplementation of zinc to implanted cattle may optimize beef production. The role of zinc in steroidal implant-induced growth processes and the effectiveness of zinc supplementation strategies are still areas that require further research.

Summary: This study aimed to determine how copper influences beta agonist-induced performance, energy metabolism, and inflammation in feedlot cattle. Results showed that copper supplementation increased liver copper concentrations, with varying effects on performance, lipolysis, and inflammation markers depending on beta agonist feeding. Strategic copper supplementation may help optimize growth in cattle receiving beta agonists.

Summary: This study aimed to evaluate the conservation status of the Lithuanian local Vistines goose breed and assess the carcass and meat quality characteristics in the breast and thigh based on sex. Monitoring the geese included in the breeding system helped assess the changes in population size and conservation status. The results showed that sex influenced the carcass composition but had no effect on meat quality. Muscle type affected meat and lipid quality parameters, with the thigh muscles showing more favorable characteristics for consumer health compared to the breast.

Summary: Cystic echinococcosis (CE) is a significant public health issue in Morocco, and vaccination of sheep with the EG95 vaccine has the potential to reduce the incidence of the disease. However, 4-monthly treatment of owned dogs with praziquantel alone did not have a major impact on E. granulosus transmission to sheep.

Summary: The use of alternative feed resources like olive cake and cactus cladodes did not significantly change the bacterial abundance and diversity in the rumen of goat kids. The rumen liquor of the goats seemed to adapt well to digest the alternative feed resources without negative effects on meat fatty acids. Incorporating these alternative feed resources could help diversify the diet of goats and reduce feed costs.

Summary: The aim of this study was to investigate the floristic composition, lifespan, life forms, phytogeographic relationships, palatability degree, and forage availability of forest rangelands in Northern Morocco. A total of 358 taxa were recorded, belonging to 228 genera and 66 families. The flora was dominated by Asteraceae, Fabaceae, Poaceae, and Lamiaceae families. The palatable plant group was highly represented with 32 species, and 93% of the identified taxa were evaluated as potential sources of forage. Forest rangelands have a high biodiversity and require rigorous protection to preserve their floristic composition and diversity.

Summary: This study evaluated the physicochemical and phytochemical parameters, biological activities, and nutritional value of pure date palm pollen and date palm pollen crushed with its spadix. Pure date palm pollen had higher humidity, water activity, and lightness (L*) than date palm pollen crushed with its spadix, but lower total soluble solids and ash contents. Pure date palm pollen exhibited higher antioxidant activity, while date palm pollen crushed with its spadix showed higher enzyme inhibitory and antidiabetic activities. Pure date palm pollen was a rich source of proteins, carbohydrates, minerals, and saturated fatty acids, while date palm pollen crushed with its spadix was a better source of unsaturated fatty acids, mainly linoleic acid. In conclusion, pure date palm pollen has higher nutritional value and can be a valuable supplement for various health applications.

Summary: Sulla flexuosa, a phenolic-rich legume, can be used as an alternative feed resource for goats without affecting milk production or physicochemical composition. Incorporating a higher amount of Sulla flexuosa in the diet improves antioxidant capacity and introduces healthier fatty acids in milk. Therefore, Sulla flexuosa can be used as an interesting alternative forage in goat diets.
