Weaning is considered the "critical window" in the piglet's life because it is associated with several stress factors, such as loss of contact with the mother and original litter, solid diet, environmental and structural changes, and the establishment of a new hierarchy. During this abrupt period, several events such as reduced feed intake, high morbidity, susceptibility to enteric infections and post-weaning diarrhoea are observed. The nutritional landscape of the piglet gut is modified, which can compromise the maturity of the gastrointestinal system, the stable intestinal microbiome...

This study aimed to evaluate the effects of rectal temperature (RT) as well as artificial insemination (AI) technique on pregnancy rates in Holstein cows and artificial insemination or embryo transfer (ET) techniques in Holstein heifers during summer. The experiments were conducted on five dairy farms in Hungary, where 1 631 data were examined. The RT was measured immediately before reproductive techniques using a digital thermometer. The effects of animal group and month on RT were analysed. The enhancement of RT until September can be seen in heifers,...

The study was conducted to investigate the effects of Broussonetia papyrifera (BP) on growth performance, rumen fermentation, digestion and meat quality in Huanghuai white goats. Diets were developed with increasing doses of BP to replace maize silage [0% (control), 15% (BP15), 30% (BP30) and 45% (BP45)]. The design was completely randomized with 4 groups of 10 animals each, totalizing 40 animals (aged 150 ± 10 days and body weight of 25.32 ± 0.52 kg). Final body weight, average daily gain and average daily feed intake increased (linear and quadratic, P < 0.05) as BP increased in the diet. The highest body weight...

The aim of the experiment was to determine how the content of lupin meal in the diet for commercial laying hens would affect the quality of fat in the egg yolk. A total of 210 Isa Brown laying hens was divided into three groups: the control group C (fed a mixture containing only soybean meal as a source of protein) and two experimental groups: EN 50% (fed a mixture containing 50% of soybean meal and 50% of white lupin seed meal, Zulika variety) and EN 100% (fed a mixture containing only white...
