Advantages on involuntary culling and herd structure dynamics

Fri, 25 Aug 2023 08:56:15 GMT

The objective of this webinar is to create awareness of how different events that happen throughout the lactation cycle impact the herd’s make-up and affect the overall economics of the dairy. Estimating the long-term effects of non-contemporary events is not an easy task considering all the moving parts happening daily at any given dairy. This is why Dr. Cabrera has developed multiple tools to link events and, via detailed calculations, determine the short- and long-term consequences, from the milk production and herd make-up to ultimately estimate the economics of implementing different management practices or using different nutritional approaches.

In this webinar, Dr. Cabrera explains how some of the simulation models were created. Then we introduce a tool developed by our technical team with Dr. Cabrera to help the end user visualize the full economic impact, taking into consideration changes in dry matter intake, milk volume and composition, health and reproduction when implementing strategies to feed diets that are amino acid balanced.

Ensure a good start to the lactation cycle of the dairy cow

Mon, 24 Apr 2023 11:00:07 GMT

This webinar gives you an appreciation for the science behind the indexes (LFI, LAI, PIRI) used to gauge the liver health of cows during the transition period. The discussion includes how to use and interpret the indexes, and their importance in guiding management practices. The conversation closes with why it is important to assure that the pre-fresh diet contains enough methionine to help cows cope with postpartum challenges.
To summarize, we discuss the importance of the transition phase to the whole lactation cycle, what areas to work on to lower unwanted cullings, and the tools we have to assess the challenges cows experience during the peripartum period.

Features: Dr. Johan Osorio, Assistant Professor, One Health, Virginia Tech, USA. Dr. Erminio Trevisi, Head of Department of Animal Sciences, Food Nutrition, Università Cattolica del Sacro Cuore, Italy. Dr. Daniel Luchini, Head of Ruminant R&I, Adisseo.

History of AA balancing and solutions for improved milk and components

Wed, 29 Mar 2023 09:02:49 GMT

This webinar will give you an appreciation for the history of the science behind amino acid (AA) balancing, the amino acids of most importance, and what improvements to expect in milk yield, fat yield and protein yield when effectively achieving target levels of lysine and methionine.
Dr. Chuck Schwab’s Ph.D. work was the catalyst for the development of AA balancing as we know it today. The first milestone to the practical implementation of AA balancing was the publication of the integrated INRA AA formulation system in 1993.
Initially AA balancing was only thought to have an effect on milk protein. Today a recent summation of 25 production trials in which rations were AA balanced using Adisseo rumen protection technologies shows clearly that AA balancing affects positively milk fat synthesis as well as milk protein.
The trial results show an increase of 1.7 kg/day in energy corrected milk (ECM), +60 g/day in milk protein and +80 g/day in milk fat, corresponding to average increases of +0.13% and +0.16% in protein and fat content respectively. Trial results have been replicated in commercial dairy farms, but formulation practices will determine how successful the results of AA balancing will be.

The Contrasting Functions of Nutrition on Reproduction in Dairy Cows

Nutrition can alter reproduction in lactating dairy cows, and the varied ways in which this occurs are discussed. Six different well-studied pathways are presented that can improve fertility and reduce pregnancy loss in dairy herds with examples provided. Attaining a high fertility cycle is emphasized.

Learn:

• How deficiencies in vitamin E near the end of pregnancy can alter reproduction in the subsequent lactation.

• How high milk production can alter reproductive traits (double ovulation, twinning, expression of heats, pregnancies per AI) and how programs like Double Ovsynch can overcome these effects.

• How high body condition score loss during the early postpartum period can reduce pregnancies per AI and how herds attain the high fertility cycle.

• The interaction of feeding rumen-protected methionine with health disorders on time to pregnancy.
