Feeding Systems And Fresh Lamb Color Stability, Koushik Mondal

Theses and Dissertations--Animal and Food Sciences

Consumers consider the surface color of fresh lamb as the indicator of freshness and wholesomeness, which affects their purchase decisions. The redox chemistry of myoglobin (Mb) determines the color of fresh lamb. Artificial raising on milk replacer (a pre-weaning strategy) as well as red clover supplementation are management strategies used in lamb production. This thesis focuses on the effects of artificial raising on milk replacer and red clover supplementation on the color and oxidative stability of fresh lamb.

In the first experiment, the effect of pre-weaning with milk replacer on the carcass attributes, color stability and lipid oxidation of lamb …

Study Of The Effect Of Feeding Highly Digestible Corn Based Calf Starter On The Growth Performance Of Calves, Shruti Srivastava

Electronic Theses and Dissertations

New corn hybrids have been developed by Masters Choice (MC) that vary in energy density and starch digestibility. These MC hybrids have lower starch densities due to an altered starch structure, which allows for greater ruminal and intestinal starch digestion. The altered starch structure of these new hybrids results in reduced feed manufacturing costs (i.e., grinding). Thirty (30) 1 to 3 d old (40.6 ± 1.72 kg) Holstein heifer calves were randomly assigned to 1 of 2 calf starters to measure growth performance of Holstein heifer calves through 8 weeks of age. Treatments were: 1) Hard starch (HS) corn calf …

Effects Of Milk Replacer And Multivitamin-Mineral Supplementation On Performance Of Heat Stressed Dairy Calves, Steven Joseph Blair

LSU Master's Theses

Seventy-one Holstein calves were used to evaluate the effects of milk replacer (MR) feeding management alone or in combination with a multivitamin-electrolyte supplement on growth and mitigation of heat stress. Milk replacer treatments consisted of Land O’Lakes Herdmaker Supreme (20% CP, 20% fat) and Land O’Lakes Warm Front (27% CP, 10% fat). Calves received either 0 or 20 ml Palamountains Calf Boost® in MR once daily. Calves were offered treatments beginning on day 4. Calves on 27% CP : 10% fat MR were fed 2.72kg MR twice daily for the first three weeks of life, and 3.86kg twice daily until …

Effects Of Alternative Protein Milk Replacer Versus All-Milk Protein Milk Replacer On Weight Gain And Grain Intake In Pre-Weaned Dairy Calves, Kayla Sandoval

Dairy Science

The objective of this study was to determine if there was a significant difference in weight gain and grain intake between Holstein calves fed milk replacer with an alternative protein source and an all-milk replacer. The study took place on a large commercial calf operation in the Central Valley of California. All calves on trial were Holstein bull calves and started the trial within three to ten days of birth. Calves on trial were weighed a total of four times. The 236 treatments did not start until the second weight was measured at about 30 days of age and was …

Effects Of Feeding Milk Replacer Once, Twice Or Three Times Daily On Growth And Performance In Neonatal Holstein Calves, Michael Thomas

LSU Master's Theses

Sixty-three neonatal Holstein calves (45 female; 18 male) were assigned to one of 3 treatments at d 2 of age to study effects of milk replacer feeding frequency on growth, performance, and health. Treatments consisted of 1X, with total amount of reconstituted milk replacer fed 1X/day at 6:00 a.m.; 2X, with total amount of reconstituted milk replacer divided into 2 equal amounts and fed at 6:00 a.m. and 5:00 p.m.; or 3X, with total amount of reconstituted milk replacer divided into 3 equal amounts and fed at 6:00 a.m., 12:00 noon, and 5:00 p.m. Calves were housed in individual hutches …

Effects Of Resistant Starch In Milk Replacer On Health And Performance In Neonatal Holstein Heifer Calves, Bethany Leann Fisher

LSU Master's Theses

Forty-two female Holstein calves were assigned to one of three treatments at d 2 of age to study the effects of adding resistant starch (RS) to the milk replacer on health and performance. Treatments were control (0g RS), 4g RS, or 8g RS mixed into the reconstituted milk replacer. Calves were housed in individual calf hutches and fed milk replacer once daily until d 42 of age. Water and an 18% crude protein calf starter were offered ad libitum beginning d 3 throughout the duration of the 56 d trial. Calves remained in their hutches until d 56 of age …

Effect Of Milk Replacer Composition On Growth And Rumen Development Of Neonatal Holstein Calves, Anthony Joseph Bridges

LSU Master's Theses

A study was conducted to determine effects of differing fat and protein levels in commercial milk replacers on the growth performance and rumen development of neonatal Holstein calves. Fifty-three calves (23 male; 30 female) were assigned to one of three dietary treatments which included 3 milk replacers (20/20; 25/15; 28/20) fed once per day at 10% of birth weight through weaning. Calves were offered a 20% CP calf starter and water free choice beginning on day 5. All calves were weaned on day 42. Body weights were measured at birth and weekly through weaning. Additionally, hip height, wither height, and …
