“…It is likely that effects taking place at the post-transcriptional level may have acted since elevated plasma cholecystokinin concentration in response to supplemental fat was observed by Choi, Palmquist, and Allen (2000) and Lin et al (2017). The CCK mRNA abundance in duodenum increased in cows fed or infused with canola oil in the abomasum, leading to an increase in plasma CCK concentrations (Chelikani et al, 2004).…”

The study aimed to evaluate nutrient digestibility and intestine gene expression in the progeny from cows supplemented during gestation and fed diets with or without rumen‐protected fat (RPF) in the feedlot. Forty‐eight Nellore steers, averaging 340 kg, were housed in individual pens and allotted in a completely randomized design using a 2 × 2 factorial arrangement (dams nutrition × RPF). Cows' supplementation started after 124 ± 21 days of gestation. The feedlot lasted 135 days and diets had the inclusion of zero or 6% of RPF. Digestibility was evaluated by total feces collection. Steers were slaughtered using the concussion technique and samples of pancreas and small intestine were collected immediately after the slaughter to analyze α‐amylase activity, and the expression of SLC5A1, CD36, and CCK and villi morphometry. Feeding RPF increased nutrients digestibility (p < 0.01). There was no effect of maternal nutrition on digestibility and α‐amylase activity in steers (p > 0.05). Duodenal expression of SLC5A1, CD36, and CCK increased in the progeny from restricted cows. In conclusion, protein restriction during mid to late gestation of dams has long‐term effects on small‐intestine length and on expression of membrane transporters genes in the duodenum of the progeny. However, maternal nutrition does not affect digestibility in the feedlot.

“…The failure of cows to meet their glucose demands for lactation leads to an impaired immune response and an increased risk of disease that may affect milk production and profitability [41]. For cow rearing, the dietary energy can be improved through fat or concentrate supplementation to alleviate NEB, but excess fat supplementation inhibits rumen microbial growth, decreases the rumen pH value, and increases the rate of subclinical ruminal acidosis [42].…”

Calcium propionate is a safe and reliable food and feed additive. It can be metabolized and absorbed by humans and animals as a precursor for glucose synthesis. In addition, calcium propionate provides essential calcium to mammals. In the perinatal period of dairy cows, many cows cannot adjust to the tremendous metabolic, endocrine, and physiological changes, resulting in ketosis and fatty liver due to a negative energy balance (NEB) or milk fever induced by hypocalcemia. On hot weather days, cow feed (TMR or silage) is susceptible to mildew, which produces mycotoxins. These two issues are closely related to dairy health and performance. Perinatal period metabolic disease significantly reduces cow production and increases the elimination rate because it causes major glucose and calcium deficiencies. Feeding a diet contaminated with mycotoxin leads to rumen metabolic disorders, a reduced reproductive rate (increased abortion rate), an increased number of milk somatic cells, and decreased milk production, as well as an increased occurrence of mastitis and hoof disease. Propionic acid is the primary gluconeogenic precursor in dairy cows and one of the safest mold inhibitors. Therefore, calcium propionate, which can be hydrolyzed into propionic acid and Ca2+ in the rumen, may be a good feed additive for alleviating NEB and milk fever in the perinatal period of dairy cows. It can also be used to inhibit TMR or silage deterioration in hot weather and regulate rumen development in calves. This paper reviews the application of calcium propionate in dairy cows.

“…Hypocalcemia plays causal roles in reducing dry matter intake, milk production, development of reproductive disorders, fertility problems, and infectious diseases [6]. For livestock, dietary energy can be improved through fat supplementation or concentrate to reduce the negative energy balance, but excess fat supplementation inhibits rumen microbial growth, reduces rumen pH value, and increases subclinical rumen acidity [7]. Therefore, studies and research tended to find a solution to this problem, and among these solutions is the addition of nutritional supplements, including calcium propionate [8].…”

This study was conducted at the ruminant research station in Abu Ghraib / livestock research department / agricultural research department / ministry of agriculture. The experiment period from 5/10/2022 to 1/4/2023, and for the production season 2022-2023. In order to study the effect of calcium propionate for different periods to study the difference of these periods in some of the productive characteristics of the Iraqi buffaloes, 15 females of Iraqi milking buffaloes were used, divided into three treatments for each treatment 5 buffaloes aged from 6-7 years, as the first treatment was T1 treatment Control without adding of calcium propionate, the second treatment T2 added 100 g calcium propionate/buffalo, and the third treatment T3 added 150 g calcium propionate/buffalo and for the periods 7 hours before calving, 24 hours after calving and 7 days after calving, calcium propionate was added to the concentrated diet. The results of the study indicate that there is a significant difference (P≤0.05) for milk production within the seventh reading in treatments T2 and T3 g compared with control T1, and a significant difference (P≤0.05) was observed in T2 for milk production within the eighth reading compared with T3 and control T1, and there were significant differences (P≤0.05) for T2 in 1st, 2nd and 3rd months for the percentage of fat compared with treatment T3 and control T1, and the results indicated a significant differences (P≤ 0.05) for treatment T3 in 1st and 3rd months for the percentage of fat compared with T2 and control T1. We conclude that the addition of calcium propionate at a ratio of 100 and 150 gm to buffalo diets during different periods improved the milk production and fat percentage of local female buffaloes.
